Brazil's Tax Reform and Short-Term Rentals in Rio for Foreign Owners

What Brazil's tax reform changes for short-term rentals

If you are buying an apartment in Rio to rent by the night or the week, Brazil's tax reform is the rule change most likely to come up in conversations with brokers, managers and other owners over the next year. The Brazil tax reform for short-term rentals is real and it is enacted, but it is narrower than the headlines suggested in early 2026, and for most foreign owners of one, two or three apartments it adds no new tax at all. This guide explains what Congress actually passed, when each part starts, who it reaches and what a foreign buyer should do before January 1, 2027, when the new federal tax replaces the old ones.

The reform swaps five older consumption taxes for two new ones. The rules that matter for rentals sit in Complementary Law 214, signed on January 16, 2025, which created the new taxes and wrote a special chapter for real estate. Complementary Law 227, signed on January 13, 2026, adjusted that chapter, including the part on short stays. The federal government then published a regulation for the new federal tax in April 2026 and amended it on July 21, 2026, setting January 1, 2027 as the date when individual taxpayers must register and issue electronic invoices.

Three questions decide whether any of this touches you. How many properties you rent out, how much rent you collected in the previous calendar year, and whether you own the apartment in your own name or through a company. A fourth question, whether your building lets you rent short-term at all, is not about tax, but a Brazilian court process that started in 2026 makes it just as important, so it has its own chapter below.

Nothing here replaces a Brazilian accountant (a contador) or lawyer. The regulations are still being written, the 2027 rate has not been published, and some points are open to interpretation. What this guide can do is tell you which questions to ask, show the numbers that already exist in the law, and help you decide whether a reform-driven change belongs in your buying plan.

CBS and IBS in plain English

Brazil used to tax consumption through a stack of separate levies: two federal contributions called PIS and Cofins, a federal tax on manufactured goods (IPI), a state tax on goods and some services (ICMS) and a municipal tax on services (ISS). Each had its own base, rates and exceptions, which is why Brazilian tax compliance has a reputation for eating so many hours. The reform replaces most of that with a dual value-added tax, the kind of sales tax used in Europe, Canada and Australia.

The two halves are the CBS, a federal contribution run by the Receita Federal, and the IBS, a tax shared by states and municipalities and run by a new joint committee. They follow the same rules, the same base and the same list of exemptions and reduced rates, and they work on a credit system: a business pays tax on its sales and subtracts the tax it already paid on its inputs. A third piece, the selective tax (IS), is an excise on items such as tobacco and alcohol and has nothing to do with renting apartments.

For property, the law created a specific regime with its own rules for sales, leases, construction and brokerage. Under that regime, ordinary leases of real estate get a 70% cut in the rates, sales get a 50% cut, and residential leases also get a monthly deduction of R$600 per property before tax is calculated. Short stays of up to 90 days are pulled out of the lease rules and taxed like hotel services, which carry a 40% cut instead. The details of each follow in later chapters.

What the reform does not do matters just as much for a buyer. It does not replace IPTU, the annual municipal property tax, or ITBI, the transfer tax you pay when you buy, although Complementary Law 227 did rewrite the national rules on how ITBI is valued. It does not touch condominium fees. And it does not change income tax: rental income is still taxed as income, under the same rules as before, whether or not you also become a CBS and IBS taxpayer. Our guide to ITBI and IPTU in Rio covers the two municipal taxes in detail.

The transition calendar from 2026 to 2033

The switch does not happen in one night. The law spreads it over eight years so that businesses, states and cities can adjust, and the dates are written into Complementary Law 214 itself. The year that matters most for rental owners is 2027, because that is when the federal half goes live at its full rate and the old federal contributions disappear.

Two features of this calendar are easy to miss. The first is that 2026 was designed as a dry run. Businesses print the new taxes on their invoices so the system can be tested, but the law waives payment for anyone who files the required returns, and anything collected is credited against PIS and Cofins. That is why the Receita Federal said in January 2026 that it was false to claim every short-term landlord would pay a new tax immediately that year.

The second is that 2027 is the real start for the federal half. From January 1, the CBS is charged at a reference rate that the Senate fixes by resolution, and PIS and Cofins stop existing. The state and municipal half stays symbolic at 0.1% in total for 2027 and 2028, then climbs from 2029 as ISS and ICMS shrink. For a rental owner who becomes a taxpayer, the bill in 2027 and 2028 is therefore mostly the federal CBS, and the full combined weight arrives only in 2033.

Rates for each year after 2026 are set the year before. A buyer looking at a ten-year hold should expect the effective tax on taxable rental activity to rise in steps between 2029 and 2033, and should not plan on today's figures holding through that period.

When an individual landlord becomes a taxpayer

The most important rule for a private owner is in Article 251 of Complementary Law 214. It says that a person, as opposed to a company, becomes a taxpayer of the regular CBS and IBS regime for leasing real estate only when two things were both true in the previous calendar year. Total revenue from leasing property passed R$240,000, and the leases covered more than three distinct properties. Both conditions must be met. One expensive penthouse earning R$300,000 a year does not qualify, and neither do five small studios earning R$150,000 between them.

To put the threshold in other currencies: at the Central Bank's PTAX selling rate of R$5.342 per dollar on October 28, 2026, R$240,000 is about US$44,900. The figure is not frozen. The law indexes it to the IPCA, Brazil's official consumer price index, so it rises with inflation, and your contador should check the current indexed number rather than the one printed in the 2025 text.

There is also a same-year trigger. Article 251 says an individual becomes a taxpayer within the current year, without waiting for January, if lease revenue runs more than 20% above the annual limit, which is R$288,000 before indexing. How that trigger interacts with the property count is one of the points to settle with your adviser, because commentators have read the drafting in different ways.

The law leaves the definition of a distinct property to the regulation, which matters for owners with a parking space sold separately, a storage unit or two units knocked into one. Joint ownership with a spouse, an inheritance and apartments held in a company are other cases where the count is not obvious. If you are near the line, get a written answer before the year closes, because the count is taken on the year that has just ended.

What Complementary Law 227 changed for short stays

The original 2025 text created some alarm among hosts. Article 253 said that leases of residential property for up to 90 uninterrupted days, made by a regular-regime taxpayer, would be taxed under the hotel rules. Read quickly, and repeated online, that became a claim that every Airbnb host in Brazil would pay hotel taxes. In January 2026 the Receita Federal published a note calling that claim false and explaining that the hotel treatment applies only to people who are already taxpayers under the new system.

Complementary Law 227 then wrote that limit into the law. It added two paragraphs to Article 253. The first says that, for short stays, the individuals treated as regular-regime taxpayers are those who meet the tests in Article 251, the same prior-year revenue and property-count tests and the same-year trigger described above. The second says that short-stay revenue counts toward those limits. In other words, there is no separate, lower threshold for hosts, and Airbnb income cannot be left out of the count either.

The same law also clarified that the R$600 deduction for residential leases is applied per property per month, and the Receita's note says the R$240,000 limit is updated by inflation every year. The note was published on January 29, 2026, and the Receita updated it again on October 28, 2026, which tells you the question is still live in the agency's inbox.

For most foreign buyers, the reform changes the paperwork of a large portfolio, not the tax on a single holiday apartment.

What Law 227 did not do is exempt short stays for people who are over the thresholds. An individual with, say, six apartments on Airbnb and R$400,000 of revenue in 2026 is a taxpayer for 2027, and the short stays in that portfolio are taxed under the hotel rules. The rest of this guide splits owners into those two groups, because the advice for each is very different.

Owners with one to three apartments

This is where most foreign buyers sit. You buy one apartment in Copacabana, Ipanema or Santa Teresa, perhaps a second one later, and rent it out through a platform or a local manager when you are not using it. Under Article 251, as the Receita reads it, as long as you rent three properties or fewer, you do not become a CBS and IBS taxpayer for rentals, no matter how much revenue they produce. The Receita's note puts it plainly: an individual with few properties pays no CBS or IBS on rent even with high rents, and remains under income tax only.

In practice that means three things for a small owner. You do not register for a CNPJ because of the reform, you do not issue electronic invoices for each stay, and you do not add CBS or IBS to the nightly price. Your rental income is taxed exactly as it was in 2025: through monthly income tax if you live in Brazil, or through withholding if you live abroad, as covered in our guide to taxes for foreign landlords in Brazil.

There is a quiet advantage in this. Hotels and companies that run short-stay apartments will be charging CBS from 2027 and the IBS on top from 2029. An individual below the thresholds charges neither. If competing operators pass some of the new tax into their prices, a small private host may find that its nightly rate looks better by comparison, although market prices depend on far more than tax and nobody can promise how that plays out in Rio.

A small owner still has reasons to pay attention. Revenue from all your Brazilian rentals counts toward the limit, including long leases, so a buyer who owns three apartments and adds a fourth is crossing a line that has real consequences the following year. Couples and families should ask how properties held jointly are counted. And anyone who plans to grow beyond three units should plan the structure first, because moving property between people or into a company later costs ITBI, notary and registry fees.

Owners with four or more apartments

The reform is aimed at people who rent property as a business, and the law draws that line at more than three properties and more than R$240,000 a year. If both were true for you in 2026, you are a regular-regime taxpayer for 2027. That status brings a set of obligations that look much more like running a small hotel company than owning a few flats: registration, invoices for each stay, monthly calculations, and taxes paid at the rates that apply to hotel services.

Take a hypothetical owner with five furnished studios in Copacabana and Leme, each earning R$62,000 in 2026 through a platform, for R$310,000 in total. Five properties is more than three, and R$310,000 is above R$240,000, so the owner enters the regime on January 1, 2027. Revenue also ran above the R$288,000 same-year trigger, which a contador may say brought the status forward into 2026. In 2026, though, the test-year waiver means nothing extra was payable by anyone who filed correctly.

From 2027 that owner charges CBS on each short stay under the hotel rules, with the rate cut by 40%, and can deduct the CBS already paid on business inputs. Inputs that may carry credits include cleaning and laundry services bought from companies, furniture and appliances, maintenance work, and platform service fees, provided the supplier charged the tax and the expense relates to the rental activity. Keeping those invoices is what turns the credit system from a theory into money.

Owners in this group have real choices to make, and most of them have a cost. Selling one unit to drop to three properties, switching some units to long leases, moving the portfolio into a company, or simply accepting the new tax and pricing it in are all options. Each has income tax, transfer tax and practical consequences that differ by person, so this is the group for whom a meeting with a contador before December is not optional. Our guide to owning property through a company or in your own name covers the structural side.

How short stays are taxed under the hotel rules

When a regular-regime taxpayer rents a residential property for up to 90 uninterrupted days, Article 253 sends the operation to the hotel chapter of the law instead of the real estate chapter. The hotel chapter is explicit that a furnished residential property counts: it defines a hotel service as supplying temporary lodging, plus any services included in the price, either in units for the exclusive use of guests or in a furnished residential property, even if not used exclusively by guests. That wording describes a typical Rio short-stay apartment.

Three consequences follow. The tax base is the value of the stay, which in practice means what the guest pays for the accommodation and any services bundled into it, such as cleaning. The rates of both CBS and IBS are cut by 40%. And the operator may claim credits on purchases, while guests, including business guests, may not claim credits on what they pay.

The difference between the two columns is large. An ordinary long lease keeps 30% of the standard rate and excludes the first R$600 a month of rent per property from the base. A short stay keeps 60% of the standard rate and has no such deduction. The Receita's January note says only that the benefit for hotel-style short stays is smaller than for residential leases, and that the combined burden does not reach the 44% figure that had circulated online.

None of this applies to an owner below the thresholds. It also helps to know what is not in the law: there is no special Airbnb tax, no nightly tourist levy created by the reform, and no rule that a platform booking changes the tax treatment by itself. The trigger is the owner's status and the length of the stay, nothing else.

What the rates could look like in 2027 and 2033

The 2027 rate has not been published yet. The law says the Senate fixes the CBS reference rate by resolution, using calculations from the Federal Court of Accounts (TCU). On September 14, 2026 the Receita Federal sent the TCU its calculation model without an estimate of the rate, and press reports expect the Senate to vote by mid-December. A projection reported in the press put the CBS near 9.2%, but it is not official, and the final figure may differ.

There is one official anchor. The Receita's January note says that once the reform is complete, an ordinary residential lease will carry an effective CBS and IBS rate of about 8%, after the 70% reduction. Working backward, that implies a combined standard rate in the region of 26 to 27%. Using 26.5% as an illustration, and the unofficial 9.2% for the CBS, you can sketch what a short stay taxed under the hotel rules might carry before any credits are deducted.

Two cautions apply to that table. First, the rates are assumptions chosen to show the scale, and the real ones will be published by the Senate for the CBS and by the joint committee and Senate for the IBS. Second, the figures are gross. A taxpayer deducts the CBS and IBS paid on business purchases, so an owner who buys cleaning, laundry, maintenance and furniture from suppliers that charge the tax will owe less than the table shows. How much less depends on how much of the cost base carries tax, and an owner who does the cleaning personally or pays informal workers will have fewer credits.

Compare an ordinary lease on the same 26.5% assumption. A long-term tenant paying R$5,000 a month in rent would be taxed on R$4,400 after the R$600 deduction, at about 7.95%, or roughly R$350 a month at full implementation. The gap between the hotel treatment and the lease treatment is one reason some larger owners are already asking whether a mix of long and short lets suits them better after 2027. For an owner below the thresholds, all of these figures are zero.

Why your 2026 bookings decide your 2027 status

Because the main test looks at the previous calendar year, the year that decides whether an individual is a taxpayer in 2027 is 2026, and it ends in about nine weeks. For owners near the lines, that makes this November and December unusually important. What you already earned in 2026 is fixed, but the number of properties you have under lease and the revenue still to come before December 31 can matter.

Some situations to check now with your adviser. If you own four or more rental properties and your 2026 lease revenue is close to R$240,000 after indexing, the bookings and contracts you sign for the rest of the year may decide your status for all of 2027. If you are buying a fourth apartment, closing in January rather than December will not change the 2026 property count if the unit is not leased in 2026, but leasing it out for New Year's week would. And if you sold or stopped renting a unit during 2026, ask whether it still counts as one of the properties rented during the year.

None of this is a reason to turn away paying guests at the busiest time of the Rio calendar. Crossing the threshold is not a penalty; it means joining a regime with credits and reduced rates that companies already deal with. The point is to know which side of the line you are on before January, so that registration, invoicing and pricing are ready on day one rather than discovered after the fact.

Keep in mind that the property count is about leases of more than three distinct properties, not about owning them. An apartment you keep empty for your own use does not add revenue, and the way the regulation counts an idle unit is one of the details to confirm. Owners who hold apartments in more than one Brazilian city should also remember that the limit is national: a flat in São Paulo and two in Rio add up to three, and a fourth anywhere in the country is the one that counts.

CNPJ registration and invoices from January 2027

Individuals who become taxpayers face a practical change that is easy to underestimate. Decree 13,075 of July 21, 2026, which amended the CBS regulation, sets January 1, 2027 as the date from which an individual who is a CBS taxpayer, or who is legally responsible for the tax, must register with the CNPJ, Brazil's business tax registry, and must issue electronic tax documents for their operations. The same date applies to some rural producers who are not relevant here.

For a short-stay owner inside the regime, that means each stay generates an electronic invoice, the monthly figures feed a tax calculation, and payments are made under the new system, which includes split payment, a mechanism where part of a card or bank payment can be sent directly to the tax authorities when the payment is processed. Registration does not turn you into a company, but it does give you a business-style identity in the tax system alongside your CPF.

The practical setup is a job for a Brazilian contador, and it is worth booking that work in November rather than in the first week of January, when every accountant in the country will be busy with the switch to the CBS. A foreign owner who lives abroad also needs someone in Brazil who can receive notices and sign returns, which is usually the same accountant or a person holding a power of attorney.

If you already have a property manager, ask now whether their contract covers invoicing and tax filings for owners who are inside the regime, and what it costs. Managers in Rio vary widely in how they handle tax, and the reform is a good moment to put the arrangement in writing. Our guide to property management for overseas owners lists what a full-service contract should cover.

How Airbnb and other platforms fit in

The law gives digital platforms a defined role. Article 22 of Complementary Law 214 treats as a platform any intermediary that connects suppliers and buyers online and controls at least one of billing, payment, the terms and conditions, or delivery. Short-stay booking sites fit that description. Platforms are responsible for the tax on bookings made through them in certain cases, and they must report the operations they handle to the Receita and the IBS committee, identifying the supplier, even when the supplier is not a taxpayer.

That reporting rule is the part every owner should absorb. Whether or not you are inside the new regime, assume that the tax authorities will see how many nights you rented and what you were paid. If your income tax filings do not match the platform data, that mismatch is easier to spot than it used to be. For most owners the answer is simply to declare rental income correctly, which you were already required to do.

For taxpayers resident in Brazil, Complementary Law 227 rewrote the platform's liability: the platform shares responsibility with the owner if it fails to report the operations, or if the owner is a taxpayer who does not issue an electronic invoice for the booking. Where split payment is available and the platform supplies the required information, it is not liable for differences in what the owner pays. The practical effect is that platforms have strong reasons to collect your tax details and to push hosts who are taxpayers toward proper invoicing.

For suppliers who live abroad, Article 22 makes the platform responsible for the tax in place of the foreign supplier on operations made through it. How that interacts with a non-resident individual who owns one Rio apartment and is below the property thresholds has not been spelled out in anything we have read, and it is a fair question to put to a tax adviser and to the platform itself. Until the guidance is clear, do not assume that a platform will or will not add tax to your bookings; check your host dashboard and statements from January.

If you live outside Brazil

Most buyinrio readers own, or plan to own, a Rio apartment while living in the United States, Canada or Europe. For income tax, that usually makes you a non-resident, and rental income from a Brazilian property is taxed in Brazil through withholding on the gross rent, commonly around 15%, with a different rate for residents of jurisdictions Brazil classes as low-tax. Brazil also expects a non-resident with Brazilian income to have a representative in the country. None of that changed with the consumption tax reform.

The CBS and IBS rules are written for persons in general, and the four-property, R$240,000 test does not say it applies only to residents. A non-resident owner of one to three apartments is therefore in the same position as a resident owner of one to three: outside the regime for rentals. A non-resident with a larger portfolio should assume the thresholds apply and should get advice on how registration, invoicing and the platform rules work for someone who lives abroad, since the platform article treats suppliers resident abroad differently.

Two pieces of the money side deserve attention in the same conversation. If you bring purchase funds into Brazil through a bank or authorized currency firm and register the investment with the Central Bank, you keep a clean path to sending rent and sale proceeds home later. And a tax treaty or foreign tax credit at home may let you offset the Brazilian tax you pay, which is a question for an adviser in your own country. Our guide on how to transfer money to Brazil to buy property covers the registration step.

Currency matters for the thresholds too. The R$240,000 limit is in reais, so a foreign owner thinking in dollars will see it move with the exchange rate. After the dollar jumped against the real at the end of October 2026, as described in our report on the election and the exchange rate, the limit is worth fewer dollars than it was a few weeks earlier, but what counts for the test is the revenue in reais, not its value in your home currency.

Owning the apartment through a Brazilian company

A company that rents out property does so as a business, so it falls under the general definition of a CBS and IBS taxpayer without any revenue or property threshold. Today such companies pay PIS and Cofins on rental revenue, and the Receita's note frames the reform as replacing that with the CBS from 2027, with the reductions and credits described above. For a company with significant costs and inputs that carry tax, the credit system may make the new burden lighter than the old one; for a company with few taxed inputs, it may not.

Companies that opt for Simples Nacional, the simplified regime for small businesses, follow their own rules, and the reform lets them choose in some cases between staying in the simplified regime and paying CBS and IBS under the regular one. That choice depends on who the customers are and how much tax the inputs carry, which is a calculation for a contador rather than a rule of thumb.

A separate 2025 law also changed the math for foreign owners who hold property through a Brazilian company. Law 15,270 of November 2025 amended the income tax rules so that profits and dividends paid or remitted abroad are subject to income tax withheld at 10%. Before that, dividends from a Brazilian company were generally exempt. For a non-resident who planned to own a rental portfolio through a company and send profits home, that withholding is now part of the comparison, along with corporate income taxes and the cost of running the company.

The same law cut income tax for residents earning up to R$5,000 a month and added a minimum tax for residents whose total income passes R$600,000 a year, both from 2026. Those changes matter to buyers who plan to move to Rio and become tax residents, and they are another reason to run any structure decision past an adviser with the numbers for your own case. Our comparison of personal and company ownership sets out the other factors, such as inheritance and the cost of moving property later.

Short stays or long leases under the new rules

For an owner below the thresholds, the reform does not change the short-versus-long decision at all, because neither option carries CBS or IBS. The usual factors still decide it: building rules, how much you want to use the apartment yourself, how much management you are willing to pay for, and how the neighborhood performs in each market. Our guides to short-term rental rules and yields in Rio and long-term rental yields work through those numbers.

The long-lease side has moved sharply in 2026. The FipeZAP residential rent index for September 2026 shows asking rents in Rio up 14.80% over twelve months and 11.86% since January, with the average advertised rent at R$61.86 per square meter per month. The same report estimates the average gross rental yield in Rio at 6.30% a year. Over the same twelve months, the FipeZAP sale index shows Rio asking prices up 5.57%, to an average of R$11,302 per square meter. Rents rising faster than prices is what pushes the long-lease yield up.

For an owner above the thresholds, the reform adds a tax argument. A long lease keeps 70% off the standard rate and excludes R$600 a month per property from the base; a short stay keeps only 40% off and has no deduction. With rents rising fast, some portfolio owners may decide that converting part of their units to long leases improves the after-tax result, especially from 2029 as the IBS grows. Others will keep short stays because nightly revenue in the busiest neighborhoods can be much higher than a monthly lease, even after tax.

Neighborhood data helps here. Our price per square meter page shows sale and rent levels by neighborhood from Secovi Rio, which lets you compare, for example, a long lease in Botafogo with a short-stay unit in Copacabana before you decide what kind of apartment to buy.

Building rules and the pending court ruling

For a short-stay buyer, the building's own rules can matter more than any tax. In Brazil an apartment building is a condominium governed by its convenção, the founding bylaws, and by decisions of the owners' assembly. Brazil's Superior Court of Justice (STJ) has dealt with short-term rentals in condominiums several times, and 2026 brought two developments that every buyer planning to rent by the night should know about.

In May 2026, according to press coverage of the decision, the STJ's Second Section held that repeated, professional short-stay use can depart from the residential purpose of a building, so that it needs the approval of the owners, with a qualified majority of two-thirds when the building's designated use has to change. Commentators stressed that this was not a general ban on short stays, and Airbnb said the decision concerned a specific case. Then in September 2026 the court took the question up under its repetitive appeals procedure, which produces a ruling lower courts must follow, and suspended related cases across the country while it decides.

The question the STJ will answer is whether a convenção that says the building is exclusively residential is enough by itself to bar short-term rentals, or whether the bylaws must prohibit them expressly. That answer could change the status of many Rio buildings whose bylaws use the standard residential wording and say nothing specific about platforms. Until the ruling, a buyer has to treat any building without clear written permission as a risk for a short-stay plan.

These checks belong in the same due diligence that covers the title and debts, described in our due diligence checklist. Building rules also affect running costs: some condominiums charge for extra cleaning of common areas or require guests to register with the doorman, and the monthly fee itself varies widely, as our guide to condominium fees in Rio explains. A building that welcomes short stays today can still change its rules by assembly vote, so ask how often the topic has come up.

Rio's city council has also debated bills to regulate short-stay platforms in recent years. We have not found one that has become law, and any new municipal rule would sit alongside the federal tax reform rather than replace it. If you are buying in 2027, check the status again before you close.

What the reform changes when you buy

Most foreign buyers in Rio buy resale apartments from private owners, and for them the purchase taxes look much as they did. The seller in a typical resale is an individual who is not a CBS and IBS taxpayer for property sales, because Article 251 only brings in individuals who sold more than three properties held for less than five years, or more than one property they built, in the previous year. So a resale from a private owner carries no CBS or IBS. You still pay ITBI, notary and registry fees, which our guide to closing costs in Rio breaks down.

New builds are different. A developer selling units is a taxpayer, so from 2027 the sale of a new apartment carries CBS, with rates cut by 50% for property sales and an adjustment that removes much of the land and earlier costs from the base. How much of that ends up in the price depends on the developer and the market. Buyers of off-plan units should ask how the contract handles tax changes between signing and delivery.

Complementary Law 227 also rewrote the national rules for ITBI, the municipal transfer tax. The amended National Tax Code says the ITBI base is the market value of the property in a normal cash sale, estimated with technical criteria such as market prices, information from notaries, registries and lenders, and the property's location and features. Cities must publish the criteria they use, and a taxpayer can contest the value with an independent appraisal under the city's own procedure. Notaries and registries must share property transaction data with the cities.

For a buyer, that means two practical things. Expect the city's ITBI valuation to track market prices closely, and keep the documents that support your price, such as the appraisal, listing history and comparable sales. If the city's value looks high, the law now gives you a route to challenge it, though how Rio implements the procedure is a matter for its own rules. Our guide to ITBI and IPTU in Rio covers the rate and when it is paid.

Buying before Carnival 2027

Carnival is the date many short-stay buyers have in mind, and in 2027 it falls early. The main Special Group parades at the Sambódromo are scheduled for Sunday, February 7, Monday, February 8 and Tuesday, February 9, 2027, according to the parade order announced in April 2026. That is a little more than fourteen weeks from today, and the CBS starts five weeks before the parades.

Fourteen weeks is a short runway for a foreign buyer. Before you can sign, you need a CPF, a Brazilian bank or currency arrangement, a negotiated price, due diligence on the property and the seller, and a deed at a notary, followed by registration at the property registry. Then the apartment needs furniture, linens, internet, photos, a listing and a manager. Each step is manageable, but together they can easily fill the whole period, and Brazil's year-end holidays slow notaries, registries and banks. Our guide to getting a CPF as a foreigner is the first step if you do not have one.

A more realistic way to think about it: Carnival 2027 is a good date to view apartments and test neighborhoods in person, and the following months are a good time to close. A buyer who closes in the first half of 2027 has time to furnish and list before the second half of the year and the next summer season, and also has time to see how the first months of the CBS work in practice. Our buyer's calendar for Rio goes through the seasons.

For an owner below the thresholds, the reform does not change Carnival pricing, because no CBS or IBS is added to the booking. For a portfolio owner inside the regime, Carnival 2027 bookings will be among the first stays invoiced under the CBS, so the registration and invoicing setup described above needs to be working by early February, and nightly prices quoted months ahead should allow for the tax. Guests who booked in 2026 for a 2027 stay are a point to raise with your contador, since the timing rules for when tax falls due are technical.

Records to keep from now on

Whatever side of the thresholds you are on, the reform rewards owners who keep clean records. The authorities will have platform data, notary data and bank data, and the simplest protection is to hold the same information yourself, organized by property and by month. A small owner needs it to prove they are below the limits; a larger owner needs it to calculate tax and claim credits.

• A list of every property you own in Brazil, with its registry number (matrícula), and for each calendar year whether it was leased, for how many days and under what kind of contract.
• Gross rental revenue by property and by month, taken from platform payout reports and lease contracts, kept separate from cleaning fees and other charges if your platform shows them separately.
• Invoices for cleaning, laundry, maintenance, furniture, appliances, utilities and management fees, with the supplier's tax number, which become credit evidence if you enter the regime.
• Your income tax filings in Brazil, including withholding receipts if you are a non-resident.
• The Central Bank registration of the money you brought in to buy, and records of every remittance abroad.
• The building's convenção, internal rules and assembly minutes on short stays, updated each year.
• IPTU bills and receipts, and the building's statement that your condominium fees are paid.

Keep digital copies somewhere you can reach from abroad, and give your contador access. If you later sell, the same records support the capital gains calculation, because improvements and acquisition costs need proof. Owners who already keep this file will find the 2027 changes much less disruptive than owners who reconstruct a year of bookings from platform emails in January.

Questions to ask a contador before January

This is the point where a professional earns their fee. A Brazilian contador who works with property owners can answer these questions for your specific case in an hour or two, and the cost is small compared with getting registration or pricing wrong for a year. If you own through a company, or own in more than one country, add a lawyer or an international tax adviser to the conversation.

• Based on my 2026 revenue and the properties I leased, am I a CBS and IBS taxpayer from January 1, 2027, and what is the indexed revenue limit for 2026?
• How does the regulation count my properties: jointly owned units, parking spaces and storage with separate registry numbers, and units I did not lease?
• Does the same-year trigger apply to me in 2026 or 2027, and what happens if I cross it mid-year?
• If I am a taxpayer, what is my registration and invoicing setup, who issues invoices for platform bookings, and how does split payment work with my platform?
• Which of my costs carry credits, and what records do you need each month to claim them?
• As a non-resident, how do the platform rules for suppliers abroad affect me, and who is my representative in Brazil?
• Should I keep the properties in my own name, move some to long leases, or use a company, once income tax, the 10% dividend withholding and transfer costs are included?
• How do bookings paid in 2026 for stays in 2027 fit the new rules?

If you are still choosing an apartment, ask the same adviser to look at the deal before you sign rather than after. Questions about whether a building allows short stays, whether a fourth unit pushes you over the line, and how to structure the purchase are cheaper to answer early.

The rules described here come from the laws and official statements published up to October 29, 2026. The CBS rate for 2027, the IBS rates from 2029, the court ruling on condominiums and further regulations are still to come, and any of them can change the numbers. This article is general information, not legal or tax advice; confirm your own situation with a Brazilian contador and lawyer before you act.

Frequently asked questions

Will I pay CBS or IBS on my Airbnb income in Rio?

Only if you are inside the new regime. An individual becomes a taxpayer for rentals after a calendar year in which lease revenue passed R$240,000, indexed to inflation, and the leases covered more than three distinct properties. Owners of one to three apartments pay no CBS or IBS on rent, however much it earns, and stay under income tax alone. Companies that rent property are taxpayers without those thresholds.

When does the new tax actually start?

2026 is a test year: CBS at 0.9% and IBS at 0.1%, with payment waived for taxpayers who file the required returns. On January 1, 2027 the CBS is charged at its full reference rate and PIS and Cofins end. The IBS stays at 0.1% in 2027 and 2028, then rises from 2029 while ISS and ICMS are phased out, and the new system is complete in 2033.

How many apartments can I rent before the new tax applies?

Up to three. The test needs more than three distinct properties leased and more than R$240,000 of lease revenue in the previous year, both at once. A single apartment with very high revenue does not qualify, and neither do several units earning less than the limit. The regulation defines what counts as a distinct property, so owners of parking spaces or jointly held units should check with a contador.

Does the reform change income tax on my rental income?

No. CBS and IBS are consumption taxes and sit on top of, not instead of, income tax. Rental income is still taxed as income: residents declare it monthly, and non-residents are generally taxed by withholding on the gross rent. A separate 2025 law did change some income tax rules from 2026, including a 10% withholding on dividends sent abroad by Brazilian companies.

What rate will short-term rentals pay under the new system?

For owners inside the regime, short stays are taxed like hotel services with the standard rate cut by 40%, and the owner can deduct tax paid on business purchases. The 2027 CBS rate has not been published. Using the Receita's own figures as a guide, a short stay might carry roughly 5.5% of revenue in 2027 and 2028 and about 16% from 2033, before credits. These are illustrations, not official rates.

Do I need a CNPJ to rent my apartment on Airbnb in 2027?

Only if you are a CBS taxpayer. A July 2026 decree requires individuals who are taxpayers or responsible for the tax to register with the CNPJ and issue electronic invoices from January 1, 2027. An owner renting one to three properties, or earning below the indexed limit, is not a taxpayer for rentals and has no reform-driven reason to register.

Can my building ban short-term rentals?

Possibly. In May 2026 the STJ's Second Section held that repeated short-stay use can require owner approval, and in September 2026 it took up, as a binding repetitive case, whether a bylaw saying the building is exclusively residential is enough to bar short stays. Until it rules, read the convenção, internal rules and assembly minutes before buying, and have a lawyer review them.

Does the tax reform change the taxes I pay when I buy?

For a resale from a private owner, there is no CBS or IBS, and you still pay ITBI plus notary and registry fees. New apartments sold by developers carry CBS from 2027, with a 50% rate cut and an adjustment for land and earlier costs. Complementary Law 227 also says ITBI is based on market value and lets buyers contest the city's valuation with an appraisal.
