Overview

IRS is Portugal’s personal income tax. Every year you declare the prior year’s income on the Modelo 3 return, and the filing window runs from 1 April to 30 June. We prepare and submit your return for residents and non-residents alike, including foreign income, so it is filed correctly and on time.

  • Residents who need their annual Modelo 3 prepared and submitted
  • Non-residents with Portuguese-source income (rent, employment, business)
  • People with foreign income who need it declared correctly in Portugal
  • Anyone who wants a plain-language explanation of their refund or tax due

What's Included

  • Review of your Portuguese and foreign income for the year
  • Preparation and submission of the Modelo 3 return
  • The official Finanças submission confirmation
  • A plain-language explanation of your refund or tax due
