The deadline for validating invoices on the Nota Fiscal Paulista Portal ended on March 2nd, an essential step for Income Tax deduction purposes. But the fiscal calendar is far from finished. Before filing the return, there are other relevant dates that taxpayers should take into consideration, as well as changes to the withholding tables that come into effect this year.
According to the Tax and Customs Authority (AT), after the validation of invoices has been completed, a new set of deadlines follows before the delivery of the income declaration.
Next dates to mark on your calendar
According to information provided by the Federal Revenue, until the end of March, taxpayers can communicate the entity to which they wish to consign 0.5% of the IRS or the benefit corresponding to the VAT input. This option can be made on the Finance Portal.
Between March 16th and 31st, there is a period to consult the expenses for deducting the collection determined by the AT. In this interval, each taxpayer must check whether the amounts calculated correspond to the expenses actually incurred.
If you detect omissions or inaccuracies, you may file a complaint regarding general family expenses or other invoices considered incorrectly.
The submission of the income tax declaration itself begins on April 1st and runs until the end of June. During this period, taxpayers can confirm automatic Income Tax, when applicable, or submit model 3 declaration.
By August 31st, the Federal Revenue Service must pay refunds or collect the tax due, as long as the declaration has been submitted within the legal deadline.
Notícias ao Minuto reminds you that compliance with these dates is crucial to avoid fines or delays in reimbursement.
New retention tables already published
In parallel with the IRS calendar, the new withholding tax tables applicable to salaries and pensions from 2026 were published. According to the Finance Portal, these tables reflect the reduction in the IRS and guarantee a monthly exemption from withholding up to 920 euros gross.
According to the order of the Secretary of State for Fiscal Affairs, Cláudia Reis Duarte, the new rates take effect from January 1, 2026 and apply to employers, including companies, public services, local authorities and private social solidarity institutions.
The new tables reflect three main changes: the reduction in rates between the second and fifth brackets, the update of the limits of the nine income brackets by 3.51% and the increase in the so-called minimum existence to 12,880 euros per year.
This mechanism ensures that taxpayers with lower incomes benefit from full or partial IRS exemption. Thus, workers and pensioners with a gross monthly income of up to 920 euros are subject to a 0% withholding rate.
According to , this update aims to align withholding tax with the changes approved in the State Budget, avoiding situations of excessive withholding throughout the year.
What changes for taxpayers
Although the deadline for validating invoices has already passed, the Income Tax process continues on several fronts. Checking deductions, making a claim and submitting the declaration are steps that require attention.
Furthermore, the new retention tables may change the monthly net amount received by workers and pensioners, especially in the intermediate brackets.
The fiscal calendar now enters a decisive phase. Meeting deadlines and following updates published by tax authorities is essential to avoid surprises when it comes time for final tax assessment.
