How to Call Finanças (Portuguese Tax Office) in English

Numbers checked against official sources: July 2026.

The Autoridade Tributária (everyone calls it Finanças) handles NIFs, tax returns, property taxes and the letters that arrive in blue envelopes. Its phone line exists, but is famously busy — this guide covers when to call, what to say, and the alternatives.

English? The line is Portuguese-first and English is not guaranteed. For non-urgent questions, the written e-balcão channel on the portal is often easier for non-speakers.

Frequently asked questions

Does the Portuguese tax office have English-speaking staff?
Not officially. Some call-centre agents manage English, but it is not guaranteed. For anything non-urgent, writing via e-balcão on the Portal das Finanças (you can write in English, though Portuguese gets faster answers) is often the smoother route.
What number do I call for Finanças?
The tax authority call centre (CAT) is 217 206 707, weekdays during business hours. Around filing deadlines expect long holds.
What should I have ready before calling Finanças?
Your NIF, your portal password in case they verify identity, and the reference number of the letter or assessment you are calling about. Prepare one specific question.
Can someone call Finanças for me in Portuguese?
Yes. CallBehalf phones Finanças on your behalf, waits on hold, asks your question in Portuguese — for example what a notice means or what the deadline is — and reports back with a transcript. The first demo call is free.
