Who Needs to File Income Tax in 2026?

Who Needs to File Income Tax in 2026? 

Every year, millions of Brazilians face the same question: do I need to file an income tax return? The answer is not always obvious, and making the wrong decision can be costly — both for those who file unnecessarily and, especially, for those who should file but don’t, risking falling into the Federal Revenue’s fine mesh.

The Individual Income Tax (IRPF) declaration is mandatory for those who meet certain criteria established by the Federal Revenue. These criteria are periodically reviewed, and the rules valid for the calendar year 2025 — whose declarations are submitted in 2026 — need to be verified directly on the official Federal Revenue website (gov.br/receitafederal), as reference values, such as income brackets, may be updated by law or normative instruction.

This article will help you understand who is required to declare, the main criteria, what happens if you fail to meet this obligation, and how to organize yourself to avoid missing the deadline. The goal is educational: to help you understand the rules so you can make informed decisions — or seek professional guidance when necessary.

What is the Individual Income Tax and Why Does It Exist

The Individual Income Tax (IRPF) is a federal tax levied on individuals’ income. It operates progressively: the higher the income, the higher the rate applied. The money collected finances public services such as health, education, and infrastructure.

The annual declaration allows the Federal Revenue to “settle accounts” with the taxpayer. Throughout the year, many taxes are withheld at the source — by employers, banks, or other institutions. In the declaration, you report all your income and deductions, and the system calculates whether you overpaid taxes (and are due a refund) or underpaid (and need to pay the difference).

Understanding whether you are required to declare is the first step to avoiding issues with the tax authorities.

Who is Required to Declare in 2026

The Federal Revenue announces the mandatory rules for each year of declaration submission. For IRPF 2026 (referring to the calendar year 2025), it is crucial to consult the specific Normative Instruction published by the Federal Revenue, as exact values may be adjusted. Generally, the historical criteria for obligation include the following situations:

Taxable Income Above the Limit

Those who received taxable income — such as salaries, pensions, rents, among others — above the limit established by the Federal Revenue for the calendar year 2025 are required to declare. This limit is defined annually by the Federal Revenue and should be checked on the official website. Don’t rely on a number a friend told you: the legislation may have changed.

Exempt, Non-Taxable, or Exclusively Taxed at Source Income

Those who received exempt income (such as indemnities, scholarships in certain cases, part of the pension for those over 65) or income exclusively taxed at source above the limit defined by the Federal Revenue may also be required. Check the updated values on the official portal.

Rural Activity

Those who had gross revenue from rural activity above the established limit, or who want to offset losses from previous years with positive results from rural activity, need to declare.

Capital Gains and Stock Market Operations

• Those who obtained capital gains from the sale of assets or rights, subject to tax payment, are required to declare.
• Those who conducted stock market operations (such as B3), commodities, futures, or similar, are required — regardless of the value of the operations.
• Those who sold shares and were exempt under the rule of sales up to R$ 20,000 in the month (for shares in the cash market) must also declare if they meet another criterion.
  

  High-Value Assets and Rights

  Those who came to possess or own assets and rights — such as real estate, vehicles, and investments — above the limit defined by the Federal Revenue on December 31 of the calendar year must also declare. Check the current limit on the Revenue’s website.

  Residence in Brazil

  Those who became a resident in Brazil in any month of the calendar year and were in this condition on December 31 are also required.

  Who is Exempt from Declaring

  Not everyone who received some income needs to declare. Some situations allow for exemption:

  • Those who received only taxable income below the established minimum limit
  • Those who had only low-value assets (below the official limit) and do not meet any other criteria
  • Workers whose tax was fully withheld at source and who have no other income or significant deductions to declare

    Attention: even if not required, it may be advantageous to declare in some cases — for example, to reclaim tax withheld at source on income below the exemption limit.

    Consequences of Not Declaring When Required

    Ignoring the obligation to declare does not make the problem disappear. The consequences can be serious:

    • Minimum fine of R$ 165.74 (historical reference value — check the current value at the Federal Revenue), which can reach 20% of the tax due
    • CPF restrictions, which can be classified as “pending regularization” or “suspended,” making it difficult to access credit, issue a passport, and other services
    • Fine mesh, with the possibility of assessment and tax collection with interest and fines
    • In severe cases, with intentional omission of large values, there may be a classification as a crime against the tax order

      The best strategy is always to regularize the situation within the deadline. If you missed the submission deadline, the Federal Revenue allows submission with a reduced fine before any formal notification.

      How to Organize for Declaration

      If you identified that you are required to declare, see the basic steps to prepare:

      1. Gather your documents — income report from the employer, pension plan statements, bank income reports, medical and dental receipts, school payment proof, among others.
      2. Download the program or access the system — the Federal Revenue provides the IRPF program for computers and the “My Income Tax” app for mobile phones, as well as the online service in e-CAC.
      3. Check your pre-filled data — since 2021, the Federal Revenue provides the pre-filled declaration for taxpayers with a silver or gold account on Gov.br. It brings information already cross-checked from employers, banks, and medical agreements.
      4. Fill in carefully — review each field. Common errors include omitting income from a second source or forgetting dependents.
      5. Pay attention to the deadline — the submission deadline is usually from March to April, but check the exact dates on the Federal Revenue’s website for 2026, as they may vary.
      6. Keep the receipt — after submission, save the delivery receipt. It is your proof that the obligation was fulfilled.
         

         Simplified or Complete Declaration: Which to Choose

         When filling out the declaration, the taxpayer can choose between two models:

         • Simplified declaration: applies a standard discount of 20% on taxable income (with a maximum limit defined by the Revenue). It is easier to fill out, but may not be the best option for those with many deductible expenses.
         • Complete declaration: allows deducting actual expenses with health, education, dependents, private pension (PGBL), among others. It requires more documentation but can result in a higher refund or lower tax to pay.

           The Federal Revenue’s program automatically compares the two forms and indicates which is more advantageous for you. Take advantage of this function before transmitting.

           Keep an Eye on Official Sources

           A very common mistake is making decisions based on previous years’ information or outdated content on the internet — including articles that seem recent but use old data. For IRPF 2026, the reliable sources are:

           • Federal Revenue of Brazil: gov.br/receitafederal — rules, deadlines, limits, programs, and official manuals
           • Official Gazette of the Union: publication of the normative instructions that define the rules for each year
           • e-CAC (Virtual Service Center): to monitor your tax situation, check pending issues, and access the pre-filled declaration

             If you have doubts about your specific situation — especially if you have varied income, stock market operations, rural activity, assets abroad, or more complex situations — consider hiring an accountant or accounting professional registered with the CRC (Regional Accounting Council).
