A REVERSAL OF LOGIC · IBS · CBS · Full non-cumulativity

Financial credit.
It reverses 30 years of tax logic.

Under the current regime, an ICMS/IPI credit arises from the physical entry of the good (physical credit). With IBS/CBS, the credit arises from the PAYMENT of the tax on the previous operation — regardless of effective taxation. A change that requires a complete review of accounting/tax processes.

One of the most profound changes of the Tax Reform is the transition from physical credit (current ICMS/IPI) to financial credit (IBS/CBS). Under the current regime, the tax credit is tied to the physical entry of the good or service into the establishment. Under the new regime, the credit arises from the payment of the tax by the previous link in the chain — regardless of whether the operation was actually taxed at the moment of sale. It reverses 30 years of logic that Brazilian lawyers and accountants have used.

01

Physical credit vs financial credit

Physical credit (current ICMS/IPI)

The taxpayer is entitled to the credit when the good or service physically enters the establishment — provided it is intended for the economic activity and subject to the non-cumulative regime. Important restrictions:

  • Freight between establishments of the same company: contested credit
  • Use-and-consumption goods: limited credit
  • Fixed assets: credit over 48 monthly installments
  • Inputs not directly integrated into the product: case by case (STJ Theme 779)

Financial credit (new IBS/CBS)

The taxpayer is entitled to the credit when it pays IBS/CBS on the previous operation — it does not matter whether the good was consumed, physically entered, or whether the previous operation was actually taxed. Paid tax? You have a credit.

Result: virtually all of the company’s purchases generate an IBS/CBS credit, without the restrictions of the current regime. This includes freight, energy, telecom, software, PPE, training — any expense where IBS/CBS was paid.

02

Full non-cumulativity

The aggregate effect of the financial credit is full non-cumulativity — every IBS/CBS paid at any point in the chain is fully used by the next link. There is no residual cumulativity.

Under the current system, even in the non-cumulative PIS/COFINS regime, there is residual cumulativity:

  • Presumed-Profit companies pay cumulative PIS/COFINS of 3.65% with no right to a credit
  • Several operation scenarios generate tax with no credit (special regimes, single-phase)
  • ICMS-ST generates ST without full crediting through the chain

All of this disappears with IBS/CBS — every link pays on what it sells, with a full credit for what it bought.

03

Practical impacts

Winning sectors

  • Industries with long chains — full capture of credits that are lost today
  • Companies with high fixed assets — immediate credit (not over 48 installments)
  • E-commerce/distributors — end of cumulative ICMS-ST in the chain

Losing sectors

  • Professional services — payroll (the largest cost) generates no credit. A substantial increase in burden.
  • Companies currently in cumulative Presumed Profit — moving from 3.65% to 8.8% effective, with a proportional credit

Pre-Reform opportunities

Before the current PIS/COFINS regime ends (Jan 2027) and ICMS ends (by 2033), there is a specific window to:

1. Recover unused physical credits

Companies with retroactive PIS/COFINS credits (Theme 779), ICMS on fixed assets (in installments), and overpaid ICMS-ST (Theme 201) can recover over the last 5 years. After the transition, recovery is still legally possible but operationally complex.

2. Model the conversion of physical credits into financial ones

There is specific regulation from the IBS/CBS Steering Committee on how accumulated PIS/COFINS credits as of 12/31/2026 are converted into a CBS balance in 2027. Companies with a high volume of accumulated credits need specific modeling.

3. Reorganize the structure to capture credit

Corporate reorganizations (spin-offs, mergers) that improve financial-credit capture from 2027 onward. Decisions must be made in 2026 with operational effect in 2027.

Frequently asked questions

What is the difference between physical credit and financial credit?
Physical credit (current system) is tied to the entry of the good/service into the establishment — with several restrictions (freight between establishments, use and consumption, fixed assets in installments). Financial credit (new IBS/CBS) is tied to the payment of the tax by the previous link — every tax paid becomes a credit, with no restrictions.
Does payroll generate an IBS/CBS credit?
No. Payroll and social charges are not part of the IBS/CBS base — so they generate no credit. It is the biggest limitation of the financial credit. Companies with a high payroll (professional services, call centers, labor-intensive industry) do not capture a credit on the largest cost of the operation. That is why these sectors are the most negatively impacted by the Reform.
What happens to my PIS/COFINS credit balance at the end of 2026?
There is specific regulation from the IBS/CBS Steering Committee (under development) on the conversion of balances. The expectation is that credits accumulated as of 12/31/2026 will be converted into a CBS balance for 2027. ICMS balances will have a specific conversion into IBS when the phase-in begins in 2029. It is important to keep rigorous documentation of accumulated credits.
Does a cumulative Presumed-Profit company gain or lose with financial credit?
It depends. Today it pays cumulative PIS/COFINS of 3.65% with no right to a credit. After CBS it pays 8.8% but with a full credit on everything it buys (energy, freight, software, etc.). Companies with a high volume of creditable inputs (commerce with heavy freight, industry with high energy) gain. Companies with few inputs (pure services) lose.
