Ask in any Portuguese freelancing group whether you have to charge IVA, and you will get two numbers back with equal confidence. Some people say €15,000. Others insist it is €25,000, and that the first group is working from out-of-date information.

At Remote Work Europe we are very used to every social media contributor being an accountant and tax lawyer in their spare time, and it’s interesting sometimes to track how these misconceptions come about and then get propagated. In this case the misunderstanding is easy to identify.

Both numbers are real. Both are current. They govern completely different things, and the people quoting them are usually answering different questions without realising it.

Here is what each one actually does.

In short: €15,000 is the VAT exemption threshold under Article 53 of the CIVA, and it applies if you have ongoing freelance activity. €25,000 is a completely separate figure — the value above which a one-off job, an ato isolado, must be registered before you carry it out. Neither replaces the other, and an ato isolado never qualifies for the Article 53 exemption at any value.

The short answer

FigureWhat it actually governsWhere it comes from
€15,000The turnover ceiling for the VAT exemption regime, if you have ongoing freelance activityArticle 53 of the CIVA
€25,000The value above which a one-off job (ato isolado) must be registered before you do itArticle 29 of the CIVA
€18,750Cross this mid-year and you leave the exemption immediately, not next JanuaryArticle 58 of the CIVA

If you have an already opened activity and invoice clients regularly, your number is €15,000. The €25,000 figure has nothing to do with you.

What is the €15,000 VAT threshold in Portugal?

Article 53 exempts you from charging IVA if you are established in Portugal, you do not carry out exports or related activities, and your national turnover in the previous calendar year did not exceed €15,000.

Two things people routinely get wrong about it.

It looks backwards, not at today. The test is what you invoiced last calendar year. Someone who billed €14,000 in 2025 is exempt through 2026 even if this year turns out much better – subject to the €18,750 rule below.

It is a threshold you cross, not an allowance you spend. The exemption is not “your first €15,000 is VAT-free”. Once you are out of the regime, IVA applies to your invoices from the relevant date onwards, not just to the amount above the line.

What if I have just opened activity?

There is no previous year to look at, so you estimate your turnover for the current calendar year yourself and put that figure on your start-of-activity declaration.

⚠️ If you start partway through the year, you estimate only what you expect to earn between your start date and 31 December. You do not scale it up to a full year.

This changed, and it is the single most common piece of out-of-date advice still circulating. Under the old rules a part-year figure was converted into an annual equivalent, so starting in July expecting €10,000 would have counted as €20,000 and put you outside the exemption. That annualisation was removed. The tax authority’s own worked example is explicit: start in July expecting €10,000 by year end, and you are inside the exemption for that year.

If you then actually earn €12,000, you stay in it the following year. If you actually earn €16,000, you leave it — file a declaração de alterações within 15 working days of year end, and the normal regime applies from 1 January.

⚠️ A second thing changed at the same time. Under the older wording your estimate had to be confirmed by the tax authority. Under the current text it is simply the amount estimated by the taxable person. If a page tells you AT must approve your figure first, or shows you a formula for annualising it, that page is describing rules that no longer apply.

One useful detail: if you did an ato isolado earlier in the same year, its value does not count towards that start-of-activity estimate.

What is the €25,000 ato isolado limit?

An ato isolado is a genuinely one-off piece of work – a single taxable transaction in a calendar year, not the start of a regular activity. You issue a one-off invoice for it without opening activity at all.

€25,000 is the point at which that stops being informal. Below it, you can do the job and issue the invoice without filing a start-of-activity declaration. Above it, you must file that declaration before carrying out the work, flagged as an ato isolado – after which the activity is closed again immediately, with no separate cessation form needed.

So €25,000 is a registration threshold. It says nothing about whether IVA applies.

Does an ato isolado get the VAT exemption?

This is the part that turns a wrong number into a real bill.

An ato isolado does not qualify for the Article 53 exemption at all – regardless of the amount. The tax authority states this explicitly, and Article 53 itself excludes anyone carrying out a single taxable operation.

The consequence is counter-intuitive enough that it is worth spelling out:

  • Bill €14,000 across the year as an ongoing freelancer under Article 53 → no IVA charged
  • Do one job for €500 as an ato isoladoIVA is charged, at whatever rate the activity attracts

The small one-off is taxed and the much larger ongoing income is not. Someone who has heard “the threshold is €25,000” and assumes their €800 one-off is comfortably under it will not charge IVA, will not remit it, and will be wrong.

(Objective exemptions under Article 9 – certain medical activities, for instance – can still apply on their own terms. That is a different exemption from Article 53.)

One further wrinkle worth knowing: the value of an ato isolado does not count towards your Article 53 turnover for the year in which you do it – but it does count towards the turnover figure that decides your position for the following year.

What happens if I cross €15,000 mid-year? The €18,750 rule

Most explanations stop at €15,000 and leave you thinking you are safe until January. You are not.

If your turnover during the current calendar year exceeds the threshold by more than 25% – that is €18,750 – you leave the exemption from that moment, not at year end. You have 15 working days from crossing it to file a declaração de alterações.

The two exits work differently, and the difference matters:

What happenedWhen you start charging IVADeadline to declare
Exceeded €15,000 in the previous calendar year1 January of the following year15 working days from year end
Exceeded €18,750 during the current yearImmediately, from that moment15 working days from crossing

If you are having a good year, €18,750 is the number to watch, not €15,000.

What changed in 2025?

Decreto-Lei n.º 35/2025 of 24 March rewrote this part of the code to implement the EU small business scheme, and it made the regime wider, not narrower.

More people can now use it. Previously the exemption was closed to anyone with organised accounting, anyone doing imports, and anyone dealing in the goods and services listed in Annex E. All three groups can now qualify, provided they meet the turnover condition.

There is now a cross-border version. If you are established in another member state you can use Portugal’s exemption, provided your EU-wide turnover stays under €100,000, you notify your home member state first, and you obtain an identification number with the EX suffix. The same works in reverse for Portuguese-established freelancers operating elsewhere in the EU.

⚠️ The old regime closed to non-established taxable persons on 1 July 2025. If you were relying on it from outside Portugal, that route no longer exists and the cross-border scheme above is the replacement.

So which number is yours?

  • Ongoing freelance activity, invoicing regularly → €15,000, and watch €18,750
  • One genuine one-off job, no ongoing activity → €25,000 decides whether you must register first, and IVA applies either way
  • Established elsewhere in the EU, working into Portugal → the cross-border scheme and its €100,000 EU-wide ceiling

The €15,000-versus-€25,000 argument is not a disagreement about the facts. It is two correct answers to two different questions, colliding in the same comment thread.
