- Taxable income above R$ 35,584 in 2025 requires filing. The previous threshold was R$ 33,888.[1]
- Other criteria also require filing, including exempt or exclusively taxed income above R$ 200,000, assets above R$ 800 million, and taxable capital gains.[1]
- The 2026 refund was paid in four lots: May 29, June 30, July 31 and August 31.[1]
- The exemption for monthly incomes up to R$ 5,000 and the reduction up to R$ 7,350 only show up in the 2027 return, which covers 2026 income.[2][1]
Why it matters
For most Brazilians, the return decides whether they owe tax or get money back. Mistakes can bring fines, delayed refunds or later charges. People who understand each year's rules can plan deductions and paperwork better.[1][2]
Who must file
The obligation depends on criteria, not total income alone. Under the rules for the 2026 return, which cover 2025 income, anyone with taxable income above R$ 35,584 must file. So must anyone with other income, such as exempt or exclusively taxed income, above R$ 200,000.[1]
Other cases require filing even at lower income. These include taxable capital gains, stock sales above R$ 40 million, rural revenue above R$ 177,920, assets above R$ 800 million, and becoming a Brazilian resident during the year. Anyone who wants to offset losses from earlier years must also file.[1]
Deadlines and refunds
In 2026, filing opened at 8 a.m. on March 23 and closed at 11:59 p.m. on May 29. Anyone who missed the deadline had to file late and could face a fine. According to the published rules, the minimum fine is R$ 165.74 and can reach 20% of the tax due.[1]
Refunds were split into four lots, with priority for taxpayers aged 80 or older. The lots were paid on May 29, June 30, July 31 and August 31. About four million taxpayers who were not required to file for 2025 but were owed money received a separate payment, provided they had a regular CPF and a Pix key registered under their CPF.[1]
How the tax is calculated
The tax follows a progressive table, in which each income band is taxed at its own rate. For the 2026 return, based on 2025 income, the exempt band runs up to R$ 28,467.20. Above that, the rates are 7.5%, 15%, 22.5% and 27.5%, each with a fixed deduction.[2]
The rate shown in the table is not the effective rate. Someone earning R$ 5,500 a month in 2025, for example, paid tax normally in that cycle, with no new exemption. The calculation also includes legal deductions, such as dependents and education expenses, each with its own limit.[2]
What changes in 2027
The main change is a new exemption for incomes up to R$ 5,000 a month, with a gradual reduction for incomes up to R$ 7,350. It was created by Law 15,270 of 2025 and took effect on January 1, 2026. However, it appears only in the 2027 annual adjustment, because it covers 2026 income.[2][1]
The exact formula for the reduction between R$ 5,000 and R$ 7,350 was not found in the sources reviewed. Check the law or the Receita Federal's official site before planning around that number.[2]
New features in the form
The pre-filled return now includes data from eSocial, variable income, DARF payments and dependents. That reduces errors, but each field still needs checking.[2]
Three new fields were added: betting income, which is taxed at 15% and requires the bets proof; an optional race and colour field; and a social name field. Anyone with betting winnings must report them accurately.[2]
What you can do
- Check whether you must file, using the income, asset and capital-gain criteria.[1]
- Keep your CPF regular and register a Pix key under your CPF before the deadline.[1]
- Keep receipts for health, education and dependents throughout the year.[1]
What we don't know yet
- The exact formula for the reduction between R$ 5,000 and R$ 7,350, which the sources reviewed did not confirm.
- The final 2027 tables and deductions, which depend on official publication by the Receita Federal.
- Whether the 2027 refund will follow the same four-lot calendar.
