The annual income tax (Imposto sobre o Rendimento das Pessoas Singulares or IRS) filing campaign is underway, and authorities are reminding self-employed workers to verify their requirements. Economically dependent freelancers may be required to submit an additional social security annex (Anexo da Segurança Social) alongside their standard Model 3 declaration. Taxpayers are encouraged to review their specific filing obligations to ensure compliance.

Context & Explainers

The IRS withholding tables are government-published schedules used by employers, pension payers and other payers to calculate how much personal income tax (personal income tax (Imposto sobre o Rendimento das Pessoas Singulares) — IRS) must be deducted from each pay period. They take into account gross pay, pay frequency, marital status and dependents; updates (usually published annually or when the budget changes) affect your monthly take-home pay and are reconciled with your annual tax return (Modelo 3).
