How to Legally Reduce Your Company's Tax Burden
Learn legal methods to reduce your company's tax burden in 2026. Vivian Sampaio shows proven paths with no tax risk.
With 26 years of practice in accounting and tax law, I can say with confidence: most Brazilian small and medium-sized companies overpay tax — not out of bad faith, but for lack of strategy. The Brazilian tax system is complex, full of regimes, rates and exceptions, and those who don’t know the rules always end up paying the maximum. In this article, I’ll show you how to legally reduce your company’s tax burden, with proven methods and no tax risk whatsoever.
Why most SMEs overpay tax
The root of the problem is structural. Brazil has one of the most complex tax systems in the world — more than 90 different taxes, monthly, annual and occasional ancillary obligations, and legislation that changes frequently. In this scenario, the business owner without specialized tax advisory tends to take the simplest path: keep the same old tax regime, pay whatever the accountant calculates, and hope not to be audited.
The result? Companies that could pay an effective tax burden of 8% pay 18%. Companies that could take advantage of legal deductions of R$ 30,000 per year don’t use them because no one mapped those opportunities. Companies that have grown beyond the break-even point of Simples Nacional (simplified tax regime) stay in the regime out of inertia, paying far more than they should.
There’s also a cultural factor: the fear of “showing up on the tax authority’s radar.” Many business owners believe that any action to reduce taxes will trigger an audit. This belief is unfounded. Tax planning within the law is not only permitted — it is expected of any responsible business management.
What it means to reduce the tax burden legally
Reducing the tax burden legally — also called tax avoidance (elisão fiscal) — means using the very instruments the legislation offers to pay less tax. This includes:
- Choosing the tax regime best suited to the company’s revenue and margin profile
- Taking advantage of deductions and tax credits provided for by law
- Structuring operations to minimize taxable events
- Using available sector and regional tax incentives
- Planning the timing of revenues and expenses to optimize the tax base
What is not a legal reduction: omitting revenue, recording fictitious expenses, issuing fake invoices, using front men, or any mechanism involving falsehood or concealment. These paths constitute tax fraud and the penalties are severe — fines of up to 150% of the tax owed, plus criminal liability.
The distinction is clear: legality is using the rules of the game in your favor. Illegality is breaking the rules. VMAHUB works exclusively within the realm of legality, and it is within that realm that enormous opportunities exist for most SMEs.
Proven methods to legally reduce business taxes, according to the applicable tax regime
Here are the main paths we use in practice with our clients.
Choosing the right tax regime
The first and most impactful method of legally reducing the tax burden is choosing the right regime. In Brazil, there are three main regimes: Simples Nacional (simplified tax regime), Lucro Presumido (presumed-profit regime) and Lucro Real (actual-profit regime). Each has a different taxation logic, and the advantage of each depends on the company’s profile.
An IT services company with annual revenue of R$ 1.5 million and a 40% profit margin can pay, depending on the regime:
- Simples Nacional (Annex III): around 13.5% on revenue = R$ 202,500
- Lucro Presumido: presumption of 32% profit, IRPJ + CSLL of 15% + 9% on that base, plus PIS/Cofins of 3.65% = effective burden close to 14.5% on revenue = R$ 217,500
- Lucro Real: if actual expenses are high, the real tax base may be only 25%, reducing IRPJ + CSLL to a calculation on R$ 375,000, with non-cumulative PIS/Cofins = effective burden may drop to 11%–12%
The difference between the best and worst scenario here is R$ 50,000 to R$ 60,000 per year — in the same company, with the same revenue, simply by changing the regime. This is legally reducing the tax burden, according to the applicable tax regime.
Full use of permitted deductions
Each tax regime allows specific deductions that many companies simply don’t take advantage of. Under Lucro Real, for example, you can deduct from the IRPJ and CSLL tax base:
- Documented operating expenses (rent, electricity, internet, supplies)
- Payroll and social charges
- Depreciation of assets
- R&D investments (with additional benefits under the Lei do Bem)
- Technical provisions for certain sectors
A company that doesn’t properly document its expenses fails to deduct amounts the law allows. I’ve seen cases where simply reorganizing the file of invoices and contracts generated tax savings of R$ 15,000 to R$ 25,000 per year in taxes.
Planning investments with tax benefits
Certain investments generate direct tax benefits. The purchase of productive equipment can generate PIS/Cofins credits under the non-cumulative regime. Investments in incentivized regions (such as the Manaus Free Trade Zone or municipalities with reduced ICMS) can generate significant reductions. Donations to children and adolescent funds, the elderly fund, and cultural projects (Lei Rouanet) allow a direct deduction from the IRPJ owed.
The central point is: these benefits are only enjoyed by those who plan. Those who act reactively lose all these opportunities.
Simples Nacional vs Lucro Presumido vs Lucro Real — when each one pays off
Choosing the tax regime is one of the most important — and most neglected — decisions in managing an SME. Here’s a practical summary:
Simples Nacional pays off when:
- Annual revenue is up to R$ 4.8 million
- The activity falls under annexes with lower rates (commerce in Annex I, industry in Annex II, specific services in Annex III)
- The company has a high payroll relative to revenue (favorable “fator R”)
- The owner values operational simplicity
Lucro Presumido pays off when:
- The company’s actual profit margin is higher than the regime’s presumption (32% for services, 8% for commerce)
- Actual expenses are low and don’t justify the controls of Lucro Real
- Revenue is between R$ 4.8 million and R$ 78 million per year
Lucro Real pays off when:
- The company’s actual profit margin is lower than the Lucro Presumido presumption
- There are significant PIS/Cofins credits to recover
- There are tax losses from prior years to offset
- The company invests heavily in R&D and wants to take advantage of the Lei do Bem

Common mistakes that make a company pay more tax
Over more than two decades advising companies, I’ve identified the most frequent mistakes that result in overpaying taxes:
1. Keeping the tax regime out of inertia: Many companies have never reviewed their regime since opening. Revenue growth, changes in the service mix and legislative changes can make the current regime disadvantageous.
2. Not documenting expenses: Real expenses the law allows you to deduct require proper tax documentation. Invoice, contract, proof of payment — without these, the deduction cannot be taken.
3. Confusing planning with tax evasion: The fear of “showing up on the tax authority’s radar” leads many owners not to use legitimate tax benefits. The result: they pay more than they should.
4. Ignoring sector incentives: Depending on the company’s sector and location, there are specific tax incentives — reduced ISS rates by municipality, ICMS exemptions for certain operations, benefits for exporting companies. These incentives are legal and were created precisely to be used.
5. Doing tax planning without integrating it with financial planning: Reducing tax without considering the impact on cash flow can create problems. For example, opting for Lucro Real may reduce annual IRPJ but increase the complexity and cost of accounting bookkeeping.
FAQ — Reducing the Tax Burden
1. Is it possible to reduce taxes without changing tax regimes? Yes. Even within the current regime, many companies have room to legally reduce the tax burden according to the applicable tax regime by taking advantage of deductions, sector tax benefits and reorganizing the way they record revenues and expenses. Reviewing tax compliance often reveals opportunities that don’t require changing regimes.
2. How long does it take to see results from tax planning? It depends on the actions implemented. Changing the tax regime produces an immediate effect in the following year. Taking advantage of tax credits can produce an effect as early as the next tax payment. More complex corporate restructurings can take 3 to 12 months to be fully implemented.
3. Does tax planning work for companies with tax debts? Yes, but with a prior step: regularizing the current tax situation. Negotiating installment plans, joining refinancing programs (when available) and cleaning up the tax liabilities are the first steps. After that, forward-looking planning can be implemented.
4. Can tax planning be done at any time of year? It can — and should — be done at any time. However, some decisions have specific windows: opting into Simples Nacional must be done in January, and the choice between Lucro Presumido and Lucro Real is exercised in the year’s first tax payment. To take advantage of these windows, the planning must be ready by the end of the previous year.
