Why Ignoring Income Tax Can Be Very Costly
Every year, millions of Brazilians wonder: do I really need to file my income tax return? For many, the answer seems obvious — “my salary is low, I owe nothing to the IRS.” But this logic contains a dangerous trap. The obligation to declare does not depend solely on how much tax you owe but on a series of criteria that, if ignored, can put your CPF under scrutiny and lead to serious financial consequences.
The Annual Adjustment Declaration of the IRPF is not just a bureaucratic ritual. It is the mechanism by which the Federal Revenue Service cross-references information from banks, employers, brokers, notaries, and health plans to verify if your declared financial situation matches reality. In an increasingly digital world, this data cross-checking is automated and often surprises taxpayers who believed they were “off the radar.”
In this article, we will explain who is required to declare in 2026, what the penalties are for those who do not submit the declaration on time (or simply do not submit it), and what to do if you have already missed the obligation in previous years. The goal is simple: to help you make informed decisions and avoid unnecessary losses.
Who Is Required to File the IRPF
The Federal Revenue Service annually defines the rules for mandatory declaration through normative instruction. For the calendar year 2025 (declaration submitted in 2026), the criteria usually follow a structure similar to previous years, but the threshold values are periodically updated. Therefore, it is essential to check the exact criteria on the official website of the Federal Revenue Service (receita.economia.gov.br) before concluding that you are exempt.
In general, you are required to declare if you fit at least one of the following situations:
- Received taxable income above the annual limit set (such as salaries, retirement, rents)
- Received exempt, non-taxable, or exclusively taxed income at source above the fixed limit (such as FGTS, indemnities, dividends)
- Obtained capital gain from the sale of assets or rights, subject to taxation
- Conducted operations on the stock exchange, futures market, or similar — in any amount
- Had possession or ownership of assets and rights above the established limit on December 31 of the calendar year
- Became a resident in Brazil in any month of the year
- Opted for the IR exemption on capital gain from the sale of residential property, followed by the purchase of another property within 180 days
Special attention for investors: those who operated on B3 — even at a loss, even if only buying stocks and not selling — may be required to declare depending on the value of the assets. If you have Treasury Direct, investment funds, CDBs, or any other financial asset, check your status.

The Consequences of Not Declaring
Failing to submit the declaration when required results in consequences that go far beyond a simple scare. Here are the main ones:
Penalty for Delay or Omission
The minimum fine for late submission is R$ 165.74, an amount that may seem small, but it doesn’t stop there. If there is tax to pay, the fine can reach 20% of the tax due, with interest calculated by the Selic rate for the period — which, in high-interest scenarios, represents a significant correction. To check the current Selic rate, visit the official website of the Central Bank of Brazil (bcb.gov.br).
The fine is applied even if the taxpayer owes no tax. Simply failing to submit the declaration on time is enough for the penalty.
CPF Under Scrutiny
When the IRS detects inconsistencies or the absence of an expected declaration, the taxpayer falls into the so-called scrutiny. This does not necessarily mean immediate action — but the CPF is “flagged” for review, which can delay or block:
- The issuance of debt clearance certificates
- Participation in public tenders and competitions
- Financing and credit operations in banks
- Inheritance and asset division processes
Tax Assessment
If the Federal Revenue identifies that you should have declared and did not — especially if there is tax to pay — you may be notified to present justifications. If you do not regularize the situation, a tax assessment notice may be issued, with fines ranging from 75% to 150% of the tax due, depending on whether fraud is characterized.
Representation for Tax Evasion
In severe cases, where the omission is intentional and involves significant amounts, the Federal Revenue may forward representation to the Public Prosecutor’s Office. Law No. 8.137/1990 provides for tax evasion crimes with imprisonment from 2 to 5 years for those who omit information to the tax authority. This scenario is rare for the common individual taxpayer but is not impossible in cases of systematic omission and significant amounts.
The IRS Data Cross-Checking: There Is No “Staying Off the Radar”
Many people still believe that if they do not declare, the IRS simply will not know. This thinking is mistaken — and increasingly dangerous.
The Federal Revenue automatically receives information from:
- Banks and financial institutions (via DIMOF and e-Financeira): transactions above certain amounts are reported
- Employers (via eSocial and DIRF): all income paid to employees is reported
- Brokers and stock exchange (via Trade Note and DARF): operations on B3 are recorded
- Notaries: transfers of real estate and other assets
- Health plans: amounts paid and reimbursed
- Pension Revenue: contributions to the INSS
When this data reaches the IRS and does not find a corresponding taxpayer declaration, the system generates an automatic alert. In 2026, with the advanced digitization of the Brazilian tax system, this comparison occurs more precisely and quickly.
Declared Late: What to Do
If you realize you were required to declare and missed the deadline, or discovered that you should have declared in previous years, there is still a way to regularize the situation — but the sooner, the better.
- Identify the open years: Check which calendar years need a declaration. The IRS accepts late declarations for the last 5 years, according to the tax decadence period.
- Gather the documents: Income report from the employer, bank statements, brokerage notes, proof of assets and expenses.
- Download the IRS program: Each year has a specific version of the IRPF program available on the Federal Revenue website.
- Fill and submit the declaration: After the official deadline, the declaration can still be transmitted normally through the program — it will automatically be identified as “late.”
- Issue and pay the fine DARF: The system itself calculates the minimum fine (or percentage, if there is tax to pay). Pay through the Receita Fácil app or at partner banks.
- Keep the receipts: Keep the delivery receipt number and the fine payment proof for at least 5 years.
When You Are Not Required to Declare
There is an important distinction: not being required to declare is different from benefiting from declaring anyway. Some people below the mandatory limits opt for voluntary declaration because:
- They have tax withheld at source to be refunded
- They want to keep their asset and income history updated with the IRS
- They need a debt clearance certificate for financial or administrative operations
If you do not fit any mandatory criteria, there is no penalty for not declaring. But evaluate whether voluntary declaration may be advantageous for your case.
Spontaneous Regularization: Still Worth It
An important principle of Brazilian tax law is that spontaneous denunciation — when the taxpayer presents themselves to the IRS before being notified — eliminates the official fine (the heavier one, from 75% to 150%). In these cases, only the late fee and Selic interest on the tax due, if any, are paid.
This means that if you have open years and have not yet been notified, rushing to regularize the situation is always the best strategy. The cost of spontaneous regularization is significantly lower than that of a tax assessment.
Conclusion: Fiscal Transparency Protects You
Keeping your fiscal life in order is not just a legal obligation — it is a way to protect your assets, your credit, and your financial reputation. The consequences of not declaring range from automatic fines to blocks that directly impact your daily finances and long-term plans.
If you have doubts about your obligation, the safest path is to consult an accountant or tax specialist registered with the CRC (Regional Accounting Council). And if you are also thinking about better organizing your investments and income, it might be a good time to understand how to structure your financial independence sustainably — as we explore in the article Living off income: how much do you really need to save.
Take care of your financial life consistently. A correctly submitted declaration is worth much more than the fine avoided by omission.
