Frequently asked questions
When is the Portuguese IRS filing window?
The Modelo 3 return for the prior year is filed between 1 April and 30 June. We prepare your return within that window once we have your documents.
Do I need to be resident to file?
No. We file for both residents and non-residents. Non-residents typically declare their Portuguese-source income; residents declare their worldwide income.
Can you handle my foreign income?
Yes. Foreign income is declared as part of the return, taking into account Portugal’s double-taxation rules. Send us the relevant documents and we include it.
Will I get a refund?
It depends on your withholding, deductions and income for the year. We explain your assessment in plain language once the return is prepared, so you know whether a refund is due or tax is payable.
