Letters from the tax authority
If the tax authority has written to you about your residence, a return or a payment, we read the letter and its deadline and prepare the reply or the corrections by that date.

Most letters that reach us concern a return that does not match the tax authority's data, a year never filed, or a change of residence the tax authority disputes. Each letter sets its own deadline.
Each service here has a defined scope, in English or Portuguese, and we quote it from your request. The advice is checked, decided and signed by our advisers.
Our services
If you have Annual Tax Support, your letters are included.
A letter from the tax authorityWe read the letter and confirm the fee before you pay, then prepare the reply by its deadline.
Putting past years rightWe set out what to correct in one or two past years and the consequences, then file each year's late or substitute return.
Tax inspection supportWe support you through a tax inspection, from the documents and explanations the inspectors ask for to the reply to the draft report, quoted once the scope is agreed.
What decides your case

What does the letter ask, and by when? The letter states what the tax authority asks for and the response deadline, counted from the notification date. This is the first point we check.
Is it a matter of fact or a point of law? A factual or divergence reply can be filed on your authorisation. Where a reply argues a point of law, we prepare it and you sign and file it in your own name. Court cases go to a lawyer and are outside this service.
Does your return have to change? A divergence notice asks you to explain or correct a mismatch with the tax authority's data. A substitute return is needed only if the return has to be corrected, and is quoted separately. A first return filed after the filing window is late.
What clients say
4.7 on Google from 43 reviewsTelmo and his team were wonderful. Reassuring, thorough and efficient.
We came to Telmo and his team when we had been miss evaluated at the end of a tax year, and after a deadline. He was able to understand our situation very quickly - give great advice and able to ensure we didnt get any other fines due additional late applications
He and his team saved us A LOT of money .
What a wonderful service. Using here on in..
I've been working with Telmo's team at Taxbordr — International Tax Advisors, Lda — for two years, and Carol has handled our filings throughout.
What I value most is that nothing is left half-finished. Our 2024 returns turned into a complicated case: while the matter was still being regularised, the Tax Authority created instalment plans on its own initiative, and the portal kept showing amounts with no real basis behind them. …
