Brazil's IBS and CBS tax reform explained for companies

IBS and CBS are the two consumption taxes replacing PIS, Cofins, ICMS and ISS in Brazil between 2026 and 2033, and they are settled by the Brazilian taxpayer. A company that sells to Brazil, hires suppliers there or runs a local subsidiary needs a clear map of what changes, when and for whom. The reform replaces a system of five consumption taxes with one of two, but it does so over eight years, with overlapping phases and regulation still being written.

At Soulbit Academy we lay out that transition for a finance lead who must decide what to review now and what to wait for. This article focuses on the tax itself: what IBS and CBS are, what they replace, the timeline, ancillary obligations and company preparation. The cash mechanics of split payment are covered in a sibling treasury article published the same day, so here it appears only in summary. Data is current as of October 2026.

IBS and CBS: what they are and which taxes they replace

IBS and CBS are the two taxes of Brazil's dual VAT: CBS (Contribuição sobre Bens e Serviços) is federal and IBS (Imposto sobre Bens e Serviços) belongs to states and municipalities, both created by Constitutional Amendment 132/2023 and detailed in Complementary Law 214/2025.

CBS replaces the federal contributions PIS and Cofins. IBS replaces the state tax ICMS and the municipal tax ISS. The federal IPI loses most of its reach, with exceptions for products that compete with Manaus Free Trade Zone goods, and a Selective Tax (Imposto Seletivo) is added on goods and services harmful to health or the environment. That selective tax is outside the scope of this article.

The underlying logic changes. Today each tax has its own base, its own credit rules and, for ICMS, its own rate in each state. The new model is non-cumulative with broad credit: a buyer who pays IBS and CBS on purchases recovers that tax as a credit, and the burden falls on final consumption. It also follows the destination principle, meaning IBS accrues to the jurisdiction where the good or service is consumed, not where it originates.

Aspect	Current system	New system (IBS and CBS)
Consumption taxes	PIS, Cofins, IPI, ICMS and ISS	CBS (federal) and IBS (states and municipalities), plus the Selective Tax on specific goods
Administered by	Receita Federal, 27 state tax authorities and thousands of municipalities	Receita Federal for CBS and the IBS Steering Committee for IBS
Credit for tax paid on purchases	Different rules by tax and by activity	Non-cumulative, with broad credit on purchases
Where tax accrues	Mostly at origin for ICMS and ISS	At destination, where the good or service is consumed
Transition	Not applicable	Test in 2026, CBS in 2027, gradual IBS until 2033

Does a foreign company pay IBS and CBS?

The Brazilian taxpayer carrying out the transaction pays them, not the foreign counterparty. A US or Colombian company selling services to a Brazilian client does not become an IBS or CBS taxpayer for that reason alone. What can happen is that the tax affects price, credit or the treatment of an import or export of services, and for those cases the rule should be validated with a Brazilian accountant.

The reform timeline: 2026 to 2033

The timeline has four milestones: a test period in 2026, real CBS collection in 2027, gradual reduction of ICMS and ISS between 2029 and 2032, and the full model in 2033.

In 2026 the test rates are 0.9% for CBS and 0.1% for IBS. They are informational and offsettable against PIS and Cofins. The Receita Federal and the IBS Steering Committee issued a joint notice on December 2, 2025 setting out the duties from January 1, 2026. According to the reform secretary, there is no effective CBS or IBS collection this year, only ancillary obligations.

In 2027 real CBS collection begins and PIS and Cofins are extinguished. From then on IBS grows in stages while ICMS and ISS shrink, from 2029 to 2032. In 2033 the new system is complete and ICMS and ISS disappear. Specialist sources differ on details, such as exactly when IPI is reduced to zero, so each date in the table should be checked against the statute and against the schedule the Receita Federal publishes.

Year	What happens	What it means for the company
2026	Test year: CBS 0.9% and IBS 0.1%, offsettable against PIS and Cofins, no effective collection	Fill the new NF-e fields and test accounting systems
2027	Real CBS collection; PIS and Cofins extinguished; gradual split payment rollout as regulated	Recalculate prices, credits and cash flow with CBS
2029 to 2032	ICMS and ISS reduced gradually while IBS rises	Two systems coexisting on the same invoice
2033	Full model with IBS and CBS; end of ICMS and ISS	A single set of credit and remittance rules

Do the final rates change in each phase?

Yes. Reference rates for IBS and CBS depend on later resolutions and on each level of government, so no final figure is definitive as of October 2026. For that reason this article cites no percentages from 2027 onward. For price planning, use the scenario set by your tax adviser and revisit it when the regulation is published.

What changes for companies: credit, pricing and invoicing

The most relevant change for a company is that tax credit becomes broad: under the new model, IBS and CBS paid on purchases of goods and services are deducted from the tax due on sales, apart from exclusions set by law.

That reshapes the cost structure in three ways. First, the price before tax and the price with tax separate more clearly, because the tax is shown explicitly. Second, suppliers that generate full credit become more attractive than those that do not. Third, long-term fixed-price contracts need clauses for the change in tax burden between 2027 and 2033.

For a small or mid-sized business selling into Brazil from another country, the effect is indirect but real. A Brazilian buyer compares offers by the credit it recovers. If your service is invoiced without the elements that support that credit, the offer may look more expensive than it is on a net basis. Talk to the client and to a local accountant before renewing contracts that run past 2027.

The relationship with authorities also changes. IBS is administered by a new Steering Committee with representatives of states and municipalities, and CBS by the Receita Federal. A company operating in Brazil will have to deal with both bodies during the transition, along with any ICMS and ISS systems still in force.

Ancillary obligations in 2026: what is already required

In 2026 the concrete duty for a Brazilian company issuing tax documents is to report IBS and CBS on the electronic invoice even though the tax is not paid, according to the joint notice from the Receita Federal and the IBS Steering Committee.

Electronic tax documents, including the NF-e, gained new fields to show both taxes. Companies that comply are exempt from remitting CBS and IBS in 2026, according to the same notice. Validation rules were relaxed during the year, and Simples Nacional filers and micro-entrepreneurs follow their own adaptation schedule, which specialist sources say applies later, from 2027.

For the finance team this means three concrete tasks in 2026. First, confirm that the ERP and the invoice issuer fill the new fields without rejections. Second, reconcile the informational CBS and IBS amounts with the books, even without payment. Third, use the year to measure the reform's effect on margins with real data rather than theoretical estimates.

Does a foreign company with no presence in Brazil need to issue an NF-e?

Not necessarily. The duty to issue electronic tax documents falls on Brazilian taxpayers and depends on the activity. A company with no establishment in Brazil that bills a Brazilian client for an exported service follows other rules, and the Brazilian counterparty is the one that must document the transaction. Confirm the treatment with a local accountant.

Split payment: the collection mechanism in brief

Split payment is the mechanism by which IBS and CBS are separated at the moment of financial settlement, so the supplier receives the net amount and the tax goes straight to the tax authority. LC 214/2025 provides for it from article 31, with models operated through payment service providers.

Specialist press, including Thomson Reuters and Radar da Reforma Tributária, placed its start of operation in 2027. The law sets no single date and delegates the gradual rollout to the Receita Federal and the IBS Steering Committee; as of October 2026, specialist press reports an optional, business-to-business-only start in 2027 and mandatory use in 2028, which we could not confirm in an official act. Until then, cash budgets should not be built on a specific scope.

What can be said with care is that split payment changes the moment a company has the money at its disposal: part of the payment never reaches its account. That cash and treasury angle is developed in the sibling article on split payment in Brazil, published the same day on Soulbit Academy.

What to prepare before 2027

A company operating in Brazil should complete five tasks before real CBS collection starts in 2027: map current taxes, review contracts, test systems, estimate cash and assign owners.

The first is to map which taxes it pays today by line of business and how much is recoverable credit. The second is to review contracts with fixed-price or tax pass-through clauses to anticipate the new burden. The third is to test the ERP and invoice issuer with the IBS and CBS fields during 2026, while nothing is collected. The fourth is to estimate split payment's effect on working capital using scenarios, not a single figure. The fifth is to name an internal owner and an outside adviser to follow the regulation.

A company paying or collecting across borders should also weigh the other costs of the operation. The IOF on foreign exchange, for example, is a separate tax applied when the exchange is settled, and we cover it in Brazil's IOF tax on foreign exchange for companies. The exchange framework for international payments is in BCB Resolution 561, and changes accumulating in the last quarter of the year are summarized in changes to Brazil's international payments in October 2026.

An illustrative exercise helps size the credit effect. Assume, as an unsourced hypothesis with no link to any Soulbit price, a Brazilian company that buys services for R$100,000 with R$20,000 of creditable tax and sells for R$150,000 with R$30,000 of tax. With broad credit it would remit R$10,000 to the tax authority, not R$30,000. The amounts are only an assumption to illustrate the mechanism; real rates depend on regulation.

What Soulbit V1 does and does not do about IBS and CBS

Soulbit V1 does not calculate, withhold or remit IBS or CBS, and it does not integrate Brazil's split payment: Soulbit is not a bank or a tax adviser, and those duties belong to each company and its advisers in Brazil.

What V1 offers is balances in stablecoins, USDC and USDT, and in fiat, dollar, euro and pound, after KYB verification, with institutional custody, payment links, collection QR codes, recurring and batch payroll, and conversion by OTC quote on request. The local bank rail exists only in Colombia. There is no local rail in Brazil inside the platform, so any conversion into reais within the Brazilian financial system goes through an authorized institution outside Soulbit, with its own tax and exchange treatment. For a comparison of the bank route and the stablecoin route at the international leg, see the Brazil-United States corridor.

The platform also offers no yield, cards, own token or native app today. Holding a stablecoin balance does not replace any Brazilian tax obligation or change the IBS and CBS burden of a transaction. The reform is, in essence, a compliance and local accounting matter, and decisions on how to structure operations with Brazil should be made with the company's tax team.
