CBS calendar remains set for January 1, 2027
After weeks of pressure from business entities for a postponement, the federal government made its final decision: the federal government decided to keep January 1, 2027 as the start date for the consumption tax reform. The confirmation came amid meetings between the Finance Minister and congressional representatives and productive sectors, and the Federal Revenue Service reinforced the commitment this week, announcing that the Contribution on Goods and Services, the CBS, will begin in January 2027.
On Tuesday (11/10), during a meeting with congressional representatives, Minister Dario Durigan was categorical in maintaining the established timeline for the gradual replacement of current taxes by the CBS and the IBS, despite calls for a postponement to 2028.
What's new: transition rule with estimated assessment
The most relevant development this week for those who operate tax systems is the announcement made by the Special Secretary of the Federal Revenue Service, Robinson Barreirinhas, this Wednesday (11/11), during a press conference on the Tax Reform Compliance Program, at the Ministry of Finance. The government will submit a proposal to the National Congress to create an optional transition rule for CBS collection, allowing companies to make an estimated calculation of the tax during the first months the system is in effect and make adjustments later, reducing difficulties in adapting to the new rules.
In practice, according to the system presented, companies will begin issuing tax documents under the new rules starting in January 2027, but the first CBS assessment, scheduled for February 2027, may be based on an estimate of the credits the company is entitled to, with the difference adjusted in the following month's assessment.
According to the secretary, the mechanism aims to provide taxpayers with greater certainty during the migration to the payment-linked credit model and to split payment, functioning as an alternative while this system is not yet fully implemented in business-to-business operations.
Compliance Program: no penalty for good-faith errors
Alongside the transition rule, Minister Dario Durigan has repeatedly reaffirmed, on different occasions, the commitment to a tax compliance program that allows for the correction of good-faith errors without the application of penalties, in addition to acknowledging the possibility of extending deadlines for applying penalties and for fulfilling ancillary obligations, such as filing returns, if necessary. The guarantee, however, does not cover deliberate noncompliance — the government's stated intent is to correct operational errors without punishing those who attempted to follow the rules.
Immediate credit for investments in capital goods
Another point highlighted by Barreirinhas in the same presentation: under the new rules, taxes paid on the purchase of machinery, equipment, real estate, and other capital goods will generate immediate credits, unlike the current model, in which these credits are often recovered gradually over several years.
Regulation gets second version in the coming days
The first version of the reform's regulation received nearly 5,000 suggestions for improvement, reviewed by the Federal Revenue Service and the other agencies involved in implementation, and a new consolidated version is expected to be published in the coming days, with work continuing after the publication of the supplementary rules still planned for this year.
Watching the rate: TCU's 11.3% under pressure
The backdrop to all of this is the debate over the CBS reference rate. The TCU (Federal Court of Accounts) recommended 11.3% for 2027, a figure the Senate has until December 15 to confirm or change by resolution. The Federal Revenue Service itself already acknowledges that, without the benefits and special regimes incorporated during regulation, the percentage could drop to around 8.5%, keeping the topic sensitive for companies' tax planning in the coming months.
DeRE also received an update this week
On the more operational side, the Federal Revenue Service and the CGIBS implemented, on November 11, starting at 7 a.m., a new version of the Beta Production environment for the Declaration of Specific Regimes (DeRE), part of the technical adjustments related to the reform and relevant for those who integrate systems with this platform. The update was carried out without the need to interrupt services, but it requires attention from IT teams that maintain active integrations with the environment.
What this means in practice for tax, accounting, and IT teams
For those who manage the ERP and the company's tax routines, this week's message is twofold: the January 2027 timeline is not expected to change, so preparation for split payment, new tax document fields, and CBS assessment must continue at the current pace; at the same time, the estimated transition rule and the compliance program signal that the government is aware the adaptation curve will be challenging and will try to ease the first few months. It's worth closely following the publication of the new version of the regulation and the supplementary rules announced for December, which should detail how the estimated assessment will work in practice within the XML and issuance APIs.
