How to Pay Less Tax Legally
Paying taxes is an obligation for all citizens, but paying more than necessary doesn’t have to be. There’s an important difference between tax evasion — which is a crime and can result in heavy fines and even imprisonment — and tax planning, which consists of using, in a legal and ethical way, the mechanisms that the law itself offers to reduce the tax burden. And that’s exactly what we’re going to talk about here.
The good news is that the Brazilian Federal Revenue Service (Receita Federal) makes available, through Income Tax legislation for individuals (IRPF), a series of deductions, exemptions, and strategies that many people simply don’t know about. The result? Brazilians fail to recover billions of reais every year due to lack of information. This article will show you, clearly and educationally, how the tax system works on income and investments, and what legal paths exist to pay less — or even get a bigger refund.
It’s important to emphasize from the start: tax rules change frequently. Some of the information described here follows the legislation in force in Brazil in 2026, but it’s always essential to consult the official Federal Revenue Service website (receita.economia.gov.br) to confirm rates, percentages, and updated deadlines before making any decision.
Understand How Individual Income Tax Works
Before planning, you need to understand what’s being taxed. IRPF applies to different types of income: salaries, rental income, investment returns, capital gains (such as selling real estate or stocks), among others.
The IR table is progressive: the higher the income, the higher the rate applied. The brackets and percentages are updated periodically by the federal government. To check the table in effect in 2026, access the Federal Revenue Service website directly — it’s the official and reliable source for these numbers.
There are two declaration models:
- Simplified declaration: applies a fixed standard discount (20% discount on the calculation base, with a limit set by law). It’s practical, but not always the most advantageous.
- Complete declaration: allows you to deduct actual expenses — with health, education, dependents, pension contributions, among others. It can result in a larger refund or lower tax to pay.
The Revenue Service software itself automatically calculates which model is most advantageous for you. Use this feature — it’s free and available in the IRPF program or in the e-CAC portal.
Legal Deductions That Many People Forget
This is one of the points where most Brazilians leave money on the table. The deductions below are provided by law and reduce the tax calculation base. Keep all receipts and invoices throughout the year.
Healthcare
Medical and dental expenses are deductible without a value limit in the complete declaration. This includes consultations, exams, hospitalizations, health plans (for both the taxpayer and dependents). It’s essential to keep all receipts.
Education
Education expenses have a deduction with an annual limit set by law (check the updated amount on the Federal Revenue website). They apply to the taxpayer and dependents, including kindergarten, elementary, middle, higher education, and postgraduate studies — but do not include free courses, language classes, or school supplies.
Dependents
Each dependent registered in the declaration generates a fixed deduction per person (amount defined annually by the Federal Revenue). Children, spouses without income, parents who depend financially on you — all can be included, as long as they meet the legal criteria.
Private Pension (PGBL)
Contributions to PGBL (Plano Gerador de Benefício Livre) can be deducted up to 12% of annual gross taxable income. Attention: this advantage only applies to those who file a complete declaration and contribute to the INSS or their own pension system. We’ll talk more about this later.
Child Support
Amounts paid by court order are fully deductible.
Tax Planning in Investments
Income tax doesn’t only appear in the annual declaration. In investments, IR can apply in very different ways depending on the product chosen. Knowing these rules allows you to make more informed decisions.
Tax-Exempt Investments for Individuals
Brazilian law provides tax exemption for returns on some products:
- LCI and LCA (Real Estate and Agribusiness Credit Letters): exempt from IR for individuals.
- CRI and CRA (Real Estate and Agribusiness Receivable Certificates): also exempt for individuals.
- Incentivized debentures: exempt from IR for individual investors, provided they are issued to finance infrastructure projects.
- Real Estate Investment Funds (FIIs): the returns (dividends) distributed are exempt from IR for individuals, provided the FII has at least 50 shareholders and the shares are traded exclusively on the stock exchange or organized over-the-counter market.
- Savings accounts: exempt from IR on returns (but note: it’s important to evaluate real returns compared to other options).
Important: exemption doesn’t mean absence of risk. These products have different risk profiles and liquidity. To better understand how to start investing, see our guide Best investments for beginners in 2026.
Decreasing IR Rate on Fixed Income
For products like CDBs, Direct Treasury, and conventional fixed income funds, IR follows a decreasing rate table: the longer the money stays invested, the lower the rate. The brackets follow this format (confirm the exact percentages on the Federal Revenue website):
| Investment period | IR rate |
|---|---|
| Up to 180 days | Higher rate |
| From 181 to 360 days | Intermediate rate |
| From 361 to 720 days | Reduced rate |
| Over 720 days | Lower rate |
The practical lesson: withdrawing investments prematurely can increase the tax paid. Planning the investment period is a simple and legal way to pay less IR.
Stock Sales: The R$ 20,000 Exemption
If you operate on the stock exchange, there’s a very important exemption rule: sales of stocks in the spot market of up to R$ 20,000 per month are exempt from IR for individuals, as long as the profit is realized within this monthly limit. Amounts above that are taxed (the rate should be verified in current legislation).
This allows investors with smaller portfolios to rebalance with greater tax efficiency. Want to understand better how the stock exchange works? Check out our article Stock exchange for beginners: where to start.
Private Pension as a Tax Planning Tool
Private pensions are, perhaps, one of the most underutilized tools for tax planning. It’s important to understand the difference between the two types:
- PGBL: allows deducting up to 12% of gross annual taxable income in IR. IR is charged on withdrawal over the total amount (contributions + returns). Recommended for those who file a complete declaration and contribute to INSS or their own pension system.
- VGBL: does not offer IR deduction. Tax applies only to returns at the time of withdrawal. More suitable for those who use simplified declaration or have already reached the PGBL deduction limit.
Both offer the option of progressive taxation (standard IR rate) or decreasing (rate decreases over time, reaching lower levels for longer periods). For those thinking long-term — like retirement — the decreasing table tends to be advantageous.
Attention: private pensions are products with their own characteristics, costs (such as administration fees and loading fees), and timelines. It’s not automatically the best option for everyone. Analyze costs carefully.
Other Little-Known Legal Paths
Asset Declaration and Updating Real Estate Acquisition Cost
The acquisition cost of a real estate property declared in IR impacts the capital gain when it’s sold. Keeping this value correctly updated (with improvements and renovations documented) reduces the taxable capital gain. Keep invoices from renovations.
IR Exemption on Residential Property Sale
If you sell your only residential property for a value of up to R$ 440,000 (confirm the current limit on the Federal Revenue website) and haven’t sold another property in the last five years, the capital gain is exempt from IR.
There’s also an exemption if the sale value is reinvested in purchasing another residential property in Brazil within 180 days.
Offsetting Losses on the Stock Exchange
Losses in stock exchange operations can be offset against future profits to reduce the IR calculation base. This control needs to be done month by month by the investor and declared correctly. Many people don’t know about this possibility and pay more tax than they should.
Important Cautions: What Not to Do
Planning taxes legally is everyone’s right. But there are traps that can turn an apparently smart strategy into a serious problem:
- Omitting income from the declaration is tax evasion, a crime.
- Declaring fictitious expenses or inflating deductions without proof is also illegal and can result in audits, fines, and interest charges.
- Using someone else’s tax ID to artificially split income may constitute tax crime.
- Shell companies created just to reduce individual IR are increasingly on the Federal Revenue’s radar, which has been cross-checking data with banks, notaries, and other agencies.
The line between tax planning and evasion is clear: everything that is legal is provided by law and can be proven with documentation.
Conclusion: Planning Throughout the Year Makes a Difference
Paying less tax legally is not a magic trick — it’s the result of information, organization, and continuous planning. Keeping receipts from health and education, understanding investment timelines, knowing the exemptions available, and choosing the right declaration model are simple actions that, combined, can make a significant difference in your finances.
The most important thing is not to leave tax planning just for the declaration period. The best decisions — like the timeline of an investment or the inclusion of a dependent — need to be made throughout the year. The Federal Revenue Service provides the IRPF program, guides, and guidance for free on its official website. Use these resources.
