Portugal's Tax Deadline is Approaching. Here's What You Need to Know.

Portugal's annual personal income tax filing window opens on the 1st of April and closes on the 30th of June. If you've been living in Portugal during 2025, now is the time to start getting your documents in order. 

Do you need to file?

You're required to file a Portuguese tax declaration if:

• You're a Portuguese tax resident: meaning you spent more than 183 days in Portugal in 2025, or maintained a permanent residency here at any point during the year.
• You're not a Portuguese tax resident, but earned income sourced in Portugal.

If either of the above applies to you, you have a legal obligation to file before the 30th of June deadline.

What does filing actually involve?

With Touchdown, the process runs in four simple steps:

1. Purchase the service and book your slot.
2. We’ll request your documents, which you can submit securely to Touchdown.
3. Should you wish, you’ll be able to book an onboarding consultation with a bar-certified Portuguese tax lawyer, who will walk through your income, flag any dual-tax implications, and confirm what's needed.
4. We file your declaration. Standard turnaround is five working days.

We handle dual filings for both US/PT and UK/PT tax situations, accounting for treaty considerations on both sides.

Where people go wrong

Income classification, missed deductions, and dual-tax treaty errors are the most common issues we see, and the most costly to fix after the fact. Getting it right the first time is far cheaper than correcting it later.

How Touchdown Helps

Touchdown specialises in relocation, tax strategy, and business setup for entrepreneurs, business owners, retirees and expats landing in Portugal.

Your declaration is filed by a bar-certified Portuguese tax lawyer, not a generalist accountant. We’ve filed hundreds of returns for expats with multiple sources of income from different jurisdictions.

The full tax return is €499. To reserve your slot now, you can purchase the Portugal Income Tax Return directly on our website. We’ll reach out to you with the required documents and next steps promptly.
