Personal Income Tax
IRS
Last updated:
The English name for IRS (Imposto sobre o Rendimento das Pessoas Singulares): the annual tax on individual income in Portugal, including freelance and self-employment earnings.
If you're coming to Portugal from another country and someone mentions "IRS," they're not talking about the American tax agency. In Portugal, IRS is the personal income tax, Imposto sobre o Rendimento das Pessoas Singulares. Every individual who earns income in Portugal is subject to it.
What expats need to know
The mechanics of personal income tax in Portugal will feel familiar if you've filed taxes elsewhere, but the details differ in ways that matter.
Progressive brackets work the same way as in most European countries. Rates start at 14.5% and climb to 48%. Each band applies only to the income within its range. Crossing into a higher bracket doesn't increase the rate on everything below.
The simplified regime changes the math. Most solo entrepreneurs in Portugal operate under the regime simplificado. Instead of deducting individual expenses, the tax authority applies a flat coefficient: only 75% of your services income and 15% of your goods income counts as taxable. This means your effective tax rate is significantly lower than the bracket percentages suggest.
For example, if you earn 40,000 euros from consulting services, your taxable income is 30,000 euros (75%). The tax is calculated on that reduced amount, not the full 40,000.
Cash-basis: when income counts
On the simplified regime, personal income tax follows cash-basis accounting. Income is taxed in the year you receive payment, not when you send the invoice. This is different from many countries where the invoice date determines the tax year.
If a client pays you on December 31st, that's this year's income. If they pay on January 2nd, it's next year's. The timing of your Recibo Verde or receipt is what matters.
Withholding: prepaying your tax bill
When Portuguese businesses pay you, they withhold a percentage of the payment and send it to the tax authority. Since 2025, the standard rate is 23% (reduced from 25% by OE2025). This is an advance on your personal income tax, credited against your annual liability. If you work mainly with foreign clients, no withholding happens, you pay the full amount when you file.
