What is the IRS?

Portugal’s Personal Income Tax (IRS) derives from the constitutional principle of tax progressivity. Individuals’ income is subject to taxation by the Portuguese Personal Income Tax Code on the annual value of income in the following categories:

  • Category A – Income from employment;
  • Category B – Business and professional income;
  • Category E – Capital income;
  • Category F – Property income;
  • Category G – Increases in assets;
  • Category H – Pensions.

The progressive nature of the IRS, which means that the tax rate increases as the taxable amount increases, helps to decrease social inequality, as enshrined in Article 104 of the Constitution of the Republic. The IRS affects all income of individuals residing in Portuguese territory.
If you do not reside in Portugal, the IRS is only levied on income obtained in national territory.

Who is responsible for submitting the IRS?

Individual taxpayers, with or without a professional activity, are responsible for submitting their personal income tax return. Parents or legal guardians are responsible for the tax return of dependents. Alternatively, you can get an accountant to do it for you. At Pearls of Portugal, we forward you directly to our trusted tax advisor partners.

How do tax returns work in Portugal?

As previously said, the IRS works by applying progressive tax rates to declared income. Income is divided into categories, each with its tax table. The final tax payable is calculated based on the sum of the taxes in each category.

The IRS is calculated individually, but couples or unmarried partners can choose to file the IRS jointly. In this case, the tax is levied on the sum of the incomes of the people who make up the household. This also includes children (expenses from education, for example, play a big part) and adults up to 25 years old – after 18, you can either submit your application individually or choose to stay in your parents’ declaration. It all depends on what’s more beneficial for you.

The tax return in Portugal is free and must be done and submitted through the AT (Autoridade Tributária e Aduaneira). To log in, you need your Tax Identification Number (NIF) and password.

What are IRS Brackets?

The IRS brackets are taxable income ranges, each with two different rates: standard and average (see table below). These rates are progressive, i.e., they increase as you move up the tax bracket. These brackets determine the gross tax (IRS payable before applicable deductions and withholdings) according to taxable income.

What has changed in 2024?

This is the new IRS bracket table (and a comparison with the current one) proposed by the government for 2024:

Types of IRS Regimes in Portugal

In Portugal, different tax regimes can be applied to residents. Here is the context for each main tax regime for nationals:

Residents (General)

They are taxed on all income earned (in Portugal and abroad).

IRS Jovem

The IRS Jovem (18 to 26 (28 for those studying for a PhD)) is a tax measure aimed at increasing the disposable income of young people at the start of their working lives. Grants partial exemption (total in the first year of the benefit, from 2024) on income from dependent work (category A) and/or self-employment (category B) for five years, consecutive or interspersed.

How the IRS works for foreigners

The IRS works differently for foreigners, depending on their situation. For example:


Mainly, non-residents only pay the IRS on income earned in Portugal. To qualify as a tax resident in Portugal, one must satisfy at least one of the following conditions:

  • Reside in Portugal for at least 183 days (consecutive or not) of the tax year
  • Have permanent residency status

For tax purposes, non-residents are foreign nationals who have resided in Portugal for less than 183 days without obtaining permanent residence status.

How to do the IRS

The tax return in Portugal is a free process that must be submitted through the AT web portal. Here is a quick summary of this process:

  1. Access the AT Portal, using your NIF and password
  2. Select “Submit Declaration” in the main menu
  3. Choose the type of declaration (Modelo 3 is the normal declaration used by most people)
  4. Filling in the declaration: You can opt for the traditional declaration (manual) or the automatic IRS, making the process less time-consuming and tedious since the declaration is already filled in and you just need to confirm the data. Usually, this is not the most beneficial option, though.
  5. Enter income and expenses: If you opt for the traditional declaration, include all your income from the previous year, such as salaries, pensions, capital income (interest, dividends), business income, etc. Add the deductible expenses you wish to declare, respecting the established limits (ceilings).
  6. Validate and submit the declaration. Only after validation can you submit the final declaration.
  7. Save the proof of electronic submission, after submitting the declaration.
Experimenting with IRS simulations (“simulações”)

Before validating and submitting your IRS, you should definitely do some simulations to see what’s more beneficial for you. For example, sometimes it’s not optimal for couples to submit their declaration together due to different expenses and income under their NIF. This also applies, for example, to children up to 25 years old, still living with their parents. The family should check if it’s better for the children to stay in the household IRS or to submit their tax returns individually, under the “IRS Jovem”. Throughout the year, you should coordinate with family what makes more sense to count as an expense for each person. We’ll look at expenses and deductions next.

A tax advisor is recommended in these cases. When you work with Pearls of Portugal, we take you directly to our trusted tax and accounting partners.

IRS Tax Return (modelo 3): where to find it and what to take into account

The IRS declaration form (Modelo 3) is available online at the Portal das Finanças. The form is filled in automatically with some data, but checking and correcting any wrong information is important. Some fields to pay special attention to are:

  • Income from employment and pensions;
  • Business and professional income;
    • Especially if you do freelance work, you must pay close attention to your invoices (‘recibos verdes’ in Portuguese)
  • Capital income;
  • Health expenses;
  • Education expenses.

You can check the declaration status (Modelo 3) using the “Consult Declaration” option as soon as you receive an email from the AT informing you that the declaration has been validated. If you want to correct the declaration, use the “Correct” option if it contains central errors. The deadline for correcting these errors is 30 days. The declaration will be considered void if you don’t correct it within the deadline.

IRS Payment: When is it paid? When do you receive it?

Every year, after submitting your tax return, the payment, or the IRS refund is eagerly awaited.

In case you need to pay

If your IRS declaration states that you must pay the state, it must be submitted by August 31 of the year you filed your tax return if the amount to be paid or received, i.e., the assessment, was made by July 31. Or by December 31 if it was made by November 30.

How to pay

There are several options for making the payment:

  • Direct debit: you can authorize a direct debit from your bank account to make the payment.
  • Multibanco: you can use the entity and reference provided in the payment instructions to pay via Multibanco.
  • Bank transfer: you can make a bank transfer to the Finanças account, using the details provided.
  • Payment at the Tax Office: you can pay in person at the Tax Office.
If you’re getting refunded

By law, the AT has until August 31 to return the over-withheld IRS. However, this is only when the tax return is submitted on time, i.e., by June 30, and validated without any discrepancies. However, the refund is usually paid earlier. Recently, the deadline has been two weeks for the automatic IRS and three weeks for the normal IRS declaration.
