How it works
What this calculadora actually does
The Brazilian IRPF Income Tax Calculator works out your brazilian income tax calculator in seconds, using the 2026 figures most UK households actually check against.
Brazilian IRPF Income Tax Calculator is built to give you a clean, explainable answer without the usual wall of ads — type the numbers, read the result, keep moving.
Run the net number, not the headline rate: that is where surprises hide. Put the real cash figures in, even if they are rough — then run the sums and the rest of this page explains what the answer means.
Brazilian personal income tax uses progressive brackets with deductions (dependants, schooling, medical, INSS). Declaration due by 31 May each year.
On this page you will see br-tax, Personal Finance and Receita Federal treated as first-class terms — each one is linked to the calculators and references that use it, so you can follow the thread without retyping queries into a search bar.
The formula we run is IRPF progressivo: 0%, 7.5%, 15%, 22.5%, 27.5%. You'll see each term laid out in the worked example below.
If it helps, jump straight to the Finance hub or compare with the UK Income Tax Calculator and the Simples Nacional Tax Calculator — those two calcs are the ones readers usually open right after this page.
A sample run with everything shown
The quickest way to sanity-check any formula is to try it on figures you recognise. Try these:
A monthly taxable base of R$3,500 (after INSS and dependants) falls in the 15% bracket with a R$394.16 deduction lump: IR = 3,500 × 0.15 − 394.16 = R$130.84. Withheld directly from payroll by the employer.
A self-employed worker with R$100,000/year taxable income, R$12,000 of dependants and R$10,000 of health-plan expense has a taxable base of R$78,000. The full-deduction model yields about R$12,000 of IRPF; the simplified 20% cap (max R$16,754) would be R$13,400. Full wins.
Every run comes back to IRPF progressivo: 0%, 7.5%, 15%, 22.5%, 27.5% — change the inputs, the structure of the answer stays.
When to use this calculadora

When to reach for something else
Every tool has an edge where it stops being the right answer. Brazilian IRPF Income Tax Calculator is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Mistakes we see over and over
Every time you run the sums for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Choosing between simplified and full declarations without simulating both. The Receita app compares automatically — never guess.
- Forgetting to sum income from all sources across the year. A R$5,000 freelance gig that goes undeclared triggers the malha fina and an auto-penalty.
- Claiming medical expenses without a formal receipt. The Receita cross-checks against the professional's CPF — missing proof drops the deduction into the audit queue.
- Not declaring paid-off assets (debt-free property, registered vehicles) assuming only income matters. The Bens e Direitos section is mandatory when total wealth exceeds R$800,000.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- Receita Federal
