Portuguese Tax Return Filing – 2023

The Portuguese tax filing season for both Corporate Income Tax and Personal Income Tax is underway.


Resident companies and other entities liable to Corporate Income Tax must file a tax return (Modelo 22) until May 31, and the IES/DA must be filed until July 15.


Resident individuals must file a tax return during April, May, and June.

An individual is considered to be a tax resident of Portugal if one of the following conditions is met: the individual stays in Portugal for more than 183 days (continuously or not) during the calendar year or twelve months, or the individual has a residential accommodation available in Portugal on any day of the fiscal year, suggesting it is his habitual residence.

Please note that if an individual also qualifies as a resident for tax purposes in other countries, the tax residency status in each country must be determined according to the provisions of the applicable Double Tax treaties.

Individuals that qualify as residents for tax purposes in Portugal are liable to Portuguese personal income tax on worldwide income.

Nonresident individuals are only liable to income tax on the income obtained in Portugal, i.e., income paid or borne by Portuguese entities or due to work performed in Portugal. When a tax withholding is not final, a yearly tax return is required.

Tax filing is required if a nonresident individual receives rental income from a Portuguese property or sells a Portuguese property.

Tax year

The tax year matches the calendar year (January 1st to December 31st). However, under certain conditions, companies may adopt a different tax year.

Please note that penalties and compensatory interest will be due if the tax return is filed after the applicable deadline. Defaulting on filing obligations can soon escalate into an inspection and a tax dispute with the Portuguese Tax Authorities. Please note that penalties apply, in addition to interest, if a tax return is filed after the deadline has elapsed.
