File Income Tax Return 2026: Step-by-Step Guide
Every year, millions of Brazilians face the same challenge: understanding whether they need to file an Income Tax return and, when they do, how to do it without errors. In 2026, the process continues within the Federal Revenue system, with specific deadlines and rules that every taxpayer should know to avoid falling into the “malha fina” — a situation where the return is held for analysis due to inconsistencies or omissions.
The good news is that filing Income Tax doesn’t need to be overly complicated. With organization, correct documentation, and attention to each step, it’s possible to fulfill the obligation with peace of mind — and even receive a refund if you paid more tax than owed during the year. The secret lies in understanding what the Federal Revenue requires, gathering the data in advance, and filling out the program or application without rushing.
In this guide, you’ll learn who is required to file in 2026, how the step-by-step filing process works, what the most common errors are, and what to do after submitting your return. Let’s get started.
Who Is Required to File in 2026
The obligation to file an Individual Income Tax Return (IRPF) is defined by the Federal Revenue based on income criteria, assets, and activities conducted in the previous calendar year — for 2026, the base year is 2025.
Attention: the exact mandatory filing limits (such as the cap on taxable income, tax-exempt income, and asset ownership) are updated annually by the Federal Revenue. Before concluding that you don’t need to file, check the current limits directly on the Federal Revenue’s official website at receita.fazenda.gov.br, in the section dedicated to IRPF 2026.
As a general rule, those typically required to file include those who:
- Received taxable income (salary, retirement, rental income, etc.) above the established limit for the year
- Received tax-exempt, non-taxable, or exclusively source-taxed income above the defined limit
- Realized capital gains on the sale of assets or rights
- Conducted operations on stock exchanges, futures markets, or similar
- Had possession of assets and rights with total value above the stipulated limit on December 31, 2025
- Became a resident of Brazil during 2025 and remained here
- Chose to declare spouse’s or dependent’s assets

Documents You’ll Need to Gather
Pre-organizing documents is the most important step — and often overlooked. Before opening the program, separate:
Income:
- Employer’s income statement (DIRF) — usually delivered by the last business day of February
- Income statements from banks and brokerages
- Proof of rent received and paid
- INSS benefits statement (available in the Meu INSS app)
- Receipts for self-employment work (RPA) or issued invoices
Deductions:
- Health plan receipts (medical, dental, hospital)
- Education expense statements (school, university, recognized technical courses)
- Private pension contribution receipts under PGBL (deductible up to 12% of taxable gross income)
- CPF number of dependents (children, spouse, etc.)
- Proof of payment of judicial alimony
Assets and Liabilities:
- Property documents (deed, purchase and sale contract)
- Vehicle documents (registration, invoice)
- Investment statements (savings, CDB, Direct Treasury, stocks, funds)
- Financing and loan contracts still outstanding
Step-by-Step: How to Complete Your Return
1. Download the Program or Use the App
The Federal Revenue provides the Declaration Generator Program (PGD) for desktop and the Meu Imposto de Renda app for mobile. Both are available free on the Federal Revenue’s official website. Download only through this channel to avoid fraud.
2. Choose the Type of Return
If you filed in previous years, you can import data from your last return, which speeds up filling in assets and registration information. Otherwise, start a new return.
3. Provide Your Personal Information
Fill in name, CPF, date of birth, voter registration, address, and banking information for receiving refunds or paying any balance owed.
4. Declare All Income
This is the most critical step. Report all income received in 2025, separating them by the correct sections:
- Taxable income received from legal entities: salaries, partner distributions, rent paid by companies
- Taxable income received from individuals: rent paid by individuals, alimony received
- Tax-exempt and non-taxable income: work-related compensation, dividends received, savings income, FGTS
- Income subject to exclusive/definitive taxation: 13th month bonus, gains on financial applications with regressive rates
5. Declare Your Assets and Rights
List all assets you owned on 12/31/2025: real estate, vehicles, investments, business stakes, credits, and more. Use the acquisition value, not the current market value — except when legislation requires specific updating.
6. Declare Liabilities and Real Encumbrances
Property mortgages, vehicle financing, and loans with outstanding balances above the limit established by the Federal Revenue must be reported in this section.
7. Choose Between Standard Deduction and Legal Deductions
Here lies an important decision:
- Standard deduction: the Federal Revenue applies a fixed percentage deduction from taxable income without requiring proof of expenses. The current percentage should be checked on the Federal Revenue’s official table, as it may be revised annually.
- Legal deductions: you report all deductible expenses (health, education, dependents, pension contributions) and subtract from the tax base. This option may be more advantageous if you have many deductible expenses.
The program itself calculates which of the two options results in lower tax — use this feature to compare before deciding.
8. Review, Calculate, and Submit
Before transmitting, use the program’s review function to identify inconsistencies. Check whether the result is tax to pay (balance due) or tax to refund (you paid more than owed during 2025).
Deadlines and Refunds in 2026
The Federal Revenue typically opens the filing period in March and closes at the end of May, but confirm the exact dates on the Federal Revenue website for 2026, as adjustments may occur. Returns filed after the deadline are subject to minimum penalties and proportional increases on the tax owed.
Refunds are distributed in batches from June to December, following a priority order:
- Seniors aged 80 and older
- Seniors aged 60 and older
- Taxpayers with physical disabilities or serious illness
- Teachers with main income from teaching
- Other taxpayers, in order of submission
Filing early increases your chances of receiving a refund in the first batches — which is relevant because how to save money every month without overcomplicating things begins precisely with planning your cash flow in advance.
Common Errors That Lead to Return Holds
Watch out for these situations that frequently block returns:
- Omitting income: the Federal Revenue cross-checks information with employers, banks, and brokerages. Any unreported income can result in audit findings
- Reporting medical expenses without proof: all receipts must include the service provider’s CPF and be available for presentation if requested
- Declaring a dependent on more than one return: each person can be a dependent on only one return
- Not declaring capital gains: selling real estate, cars, or stocks with a profit generates specific tax obligations — often requiring monthly payments via DARF, independent of the annual return
- Incorrect banking information for refunds: causes delays or prevents refund receipt
What to Do After Submitting Your Return
After transmitting, keep the delivery receipt (protocol number) and track your return’s processing on the Federal Revenue website or app. If your return is held for review, you’ll receive a notification and can submit an amended return correcting the information before any formal audit.
Keep all documents used for at least five years — that’s the timeframe the Federal Revenue has to question reported information.
Practical Conclusion
Filing your Income Tax return in 2026 requires attention, but it’s not impossible for those who organize in advance. The key is gathering documents calmly, understanding which taxation method is most advantageous for your profile, and reviewing everything before submitting. Always remember: when in doubt, an accountant or specialized professional can prevent costly mistakes. For broader personal finance questions — like understanding the impact of inflation on your purchasing power — continuous financial education makes all the difference in your decisions throughout the year.
