Choosing the Right Corporate Tax Regime for your Brazilian Company

A company sets up its Brazilian subsidiary, signs its first contracts, and spends year one doing what year one looks like everywhere: hiring, importing, building a pipeline, losing money. Then the tax bill arrives, and it is charging tax on a profit the company never made.

Nothing went wrong administratively. The accountant did exactly what was asked. The problem is that nobody told you or even asked about which of Brazil’s two corporate tax regimes that you wanted to be part of. No one ran the numbers because you didnt know and now your locked into a system for the next 12 months. 

This is one of the most common and most expensive errors foreign investors make when they enter Brazil. It is also completely avoidable.

Why this is a decision at all

Every company in Brazil pays corporate tax under one of two systems: Lucro Presumido or Lucro Real. You choose. There is no default, and the two can produce materially different tax bills on identical revenue. For this reason alone, its critical that companies have it on their radar.

• The choice is annual, and it locks. You commit when you make your first corporate tax payment of the year, for most companies on Lucro Presumido, that is the end of April, and you stay in that regime until 31 December. If the year turns out differently than forecasted, there is no switching mid-stream.
• The simpler option is not the safer option. New subsidiaries default to Lucro Presumido because it is easier to administer. In a first or second year, when margins are thin and setup costs are heavy, that is often the more expensive choice by a wide margin.

A note on Simples Nacional: there is a third, simplified regime designed for small Brazilian businesses. It is generally unavailable to companies with foreign shareholders, so foreign-owned entities can set it aside.

Lucro Presumido: tax on a margin the government assumes you made

How the Lucro Presumido system works is that the tax authority assumes a profit margin for your industry and taxes that figure, regardless of what you actually earned. For trade and industry the assumed margin is 8% for IRPJ and 12% for CSLL. For most services it is 32%. Tax is calculated quarterly. Some regulated activities use different assumed margins so every company needs to review.

Think of it as a flat rate applied to a hypothetical version of your business. If your real business outperforms that hypothetical, you win. If it underperforms, you pay tax on profit that does not exist.

The advantages are real: the tax calculations is simple, the bill is forecastable, and bookkeeping requirements are moderate. If your actual margin comfortably beats the assumed one, this is the cheaper regime.

The risk is the one that catches new entrants. The company remains liable for tax even when the real margin is lower, including in a loss-making year.

Generally best for: companies under R$78M in annual revenue with a healthy, stable margin relative to the assumed rate for their sector.

Lucro Real: tax on what you actually earned

Tax is calculated on real, audited profit after costs. It requires proper ongoing accounting, but it is the only regime that allows recovery of tax credits on purchases, and the only one that makes sense if you are not yet turning a solid profit.

No profit, no income tax. That single feature is why it suits companies in their early years.

Credits are recoverable on inputs, imports and purchased services. For a business importing equipment or technology into Brazil, or buying significant third-party services locally, this is not a rounding error — it is often the largest single difference between the two regimes.

The cost is full, ongoing professional accounting. There is no way around it.

Best for: companies above R$78M (where it is mandatory), and any company with thin margins, heavy input costs, or early-stage losses, which probably describes most subsidiaries in their first years.

Three things in motion during 2026

• Assumed margins have gone up, on two different schedules. Lei Complementar 224/2025 added a 10% surcharge to the assumed profit margins used in Lucro Presumido, for companies billing over R$ 5M a year. It applies to IRPJ from 1 January 2026 but only reaches CSLL from 1 April 2026 — so the two taxes step up at different points in the year. The change is being challenged, with constitutional actions pending before Brazil’s Supreme Court and injunctions already granted to some taxpayers.
• The wider tax reform is phasing in. New taxes, CBS and IBS, will gradually replace PIS, COFINS, ICMS and ISS through 2033. One side effect worth watching: because CBS will be charged outside the invoice price rather than embedded in revenue, it will not count toward gross revenue the way PIS/COFINS does today — which should widen the effective ceiling of the R$ 78M Lucro Presumido cap in real terms as this phases in from 2027.
• Mandatory carve-outs still catch people. Banks, insurers, factoring companies and a few others must use Lucro Real regardless of revenue. This is not new, but it is easy for a first-time entrant to miss.

Conclusion

Companies entering Brazil tend to treat the tax regime as an accounting formality, a box the local accountant ticks somewhere between incorporation and the first invoice. It is not. It is a commercial decision that locks companies in for twelve-months, and the worst part is that often foreign managers have no idea about it.

For mining technology and equipment suppliers, year one is a pilot installation at one site, imported hardware sitting on the balance sheet as a loan from the parent company, engineers flying in for commissioning, and a sales cycle measured against mine budget rounds rather than quarters. Revenue lags cost by eighteen months, sometimes longer. Meanwhile the two largest line items, imported equipment and locally purchased technical services, are precisely the costs that generate recoverable credits.

Every one of those facts points to Lucro Real. And yet the default, chosen for simplicity at incorporation in brazil, is the regime that taxes an assumed margin the company has not earned, on services at a presumed 32%, while the credits sitting inside its import costs go unrecovered.

The consequence is not just a tax bill. It is a landed cost you cannot bring down, quoted into a market where your competitor’s Brazilian entity is recovering the same credits you are writing off. In a sector where equipment deals are won on total cost of ownership, that difference shows up in the pricing, and the client sees it.
