IRS in Portugal is the annual personal income tax return. If you are a foreigner living, working, studying, freelancing, renting property, receiving foreign income, or using foreign bank/investment accounts while resident in Portugal, IRS can become confusing quickly.
Many foreigners only ask “Do I need to file IRS?” But the better question is:
“Am I a Portuguese tax resident, what income did I receive, which country did it come from, and what does Portal das Finanças already know about me?”
This guide explains IRS Portugal for foreigners in simple English: who usually needs to file, the main deadlines, tax residency, foreign income, Anexo J, e-Fatura, englobamento, and the common mistakes that cause problems.
Last verified: April 26, 2026. Portuguese tax rules, forms, tax brackets, deductions, and filing screens can change. Always check Portal das Finanças or speak with a qualified Portuguese accountant before filing.
Quick Answer
- IRS means: Imposto sobre o Rendimento das Pessoas Singulares.
- In English: Personal income tax.
- Where do you file it? Online through Portal das Finanças.
- Normal filing period: 1 April to 30 June for income from the previous year.
- Refund or payment deadline: Usually up to 31 August for returns submitted within the normal deadline.
- Tax residents: Usually declare worldwide income, including income from Portugal and abroad.
- Non-residents: Usually declare Portuguese-source income that has not already been taxed at final withholding rates.
- Foreign income: Usually goes in Anexo J if you are tax resident in Portugal.
- Foreign bank or investment accounts: If you are resident and have foreign deposit/security accounts, Anexo J may be relevant even if the account produced little or no income.
- Can foreigners use IRS Automático? Sometimes, but many foreigners with foreign income, self-employment, special regimes, or complex situations should be careful and may need Modelo 3 instead.
- Should you hire an accountant? If you have foreign income, self-employment, NHR/IFICI, crypto/investments, rental income, capital gains, or tax residency questions, it is usually safer to get professional help.

What Is IRS in Portugal?
IRS is Portugal’s personal income tax.
Gov.pt explains that IRS applies to income of people resident in Portugal and to non-residents who earn income in Portugal. The amount depends on the income earned, applicable tax rates, and deductions allowed by law.
In practice, IRS is the annual moment when you tell the Portuguese Tax Authority what income you had and whether you owe tax or are due a refund.
IRS Timeline for Foreigners
The IRS year usually works like this:
| Period | What happens |
|---|---|
| During the tax year | You receive income, ask for invoices with NIF, and collect documents |
| Early following year | You check e-Fatura, household details, and deduction information |
| 1 April to 30 June | You submit IRS through Portal das Finanças |
| After submission | AT processes the declaration and issues a settlement |
| Up to 31 August | Refund or tax payment deadline for returns submitted within the normal period |
The most important filing window is 1 April to 30 June.
Do not wait until the last week if you have foreign income, missing invoices, or an accountant who needs documents.
First Question: Are You Tax Resident in Portugal?
Your tax residency is the starting point.
Portal das Finanças says you are considered tax resident in Portugal when you meet one of these conditions:
- You stayed in Portugal for more than 183 days, consecutive or interrupted, in any 12-month period beginning or ending in the tax year.
- You had a home in Portugal that clearly shows your intention to keep and occupy it as your habitual residence, even if you stayed for fewer than 183 days.
Your tax residency matters because it affects what income Portugal expects you to declare.
Tax resident vs non-resident
| Status | General IRS effect |
|---|---|
| Tax resident in Portugal | Usually declare worldwide income |
| Non-resident | Usually declare only Portuguese-source income that must be reported |
A common foreigner mistake is thinking immigration residence and tax residence are exactly the same. They are related, but not identical.
You can have an AIMA residence process and still need to separately check your tax address and tax residency status with Finanças.
Second Question: Did You Update Your Tax Address?
Before filing IRS, check your tax address in Portal das Finanças.
Gov.pt says people should make sure their current situation is correctly registered with the Portuguese Tax Authority before filing, especially their tax address.
This matters because your tax address can affect:
- Whether AT treats you as resident or non-resident
- Which income Portugal expects you to declare
- Whether you receive official notifications
- Possible fines or penalties
- Eligibility for some tax advantages
If you moved to Portugal but did not update your tax address, or if you left Portugal but did not update it abroad, your IRS situation can become messy.
Do Foreigners Need to File IRS in Portugal?
The answer depends on residency and income.
You usually need to file if you are resident in Portugal and received income
Residents in Portugal who receive income from employment, self-employment, business/professional work, pensions, capital, property, or assets may need to submit an IRS return.
Residents should normally include income from the household, including income from outside Portugal.
You may need to file if you are non-resident but earned income in Portugal
Gov.pt says non-residents may need to file if they obtained income in Portugal, such as property income or capital gains, and the income was not already taxed through final withholding.
You may be exempt in simple low-income cases
Some people are exempt from submitting an IRS return. Portal das Finanças lists examples, including people who only received certain withholding-taxed income and do not want to include it in IRS, or employment/pension income up to a stated threshold under specific conditions.
Do not assume exemption applies to you. Foreigners with foreign income, self-employment, rental income, capital gains, or foreign accounts should be extra careful.
Foreign Income: The Big Issue for Foreigners
If you are tax resident in Portugal, foreign income is one of the biggest IRS risk areas.
Portal das Finanças says residents in Portugal must declare all income, whether obtained in Portugal or abroad. Foreign income is normally declared in Anexo J of the Modelo 3 IRS return.
Foreign income can include:
- Foreign salary
- Foreign freelance income
- Foreign pension
- Foreign bank interest
- Foreign dividends
- Foreign investment income
- Foreign rental income
- Foreign capital gains
- Income from accounts or assets outside Portugal
- Some income paid abroad even if you live in Portugal
The key point is this:
If you are tax resident in Portugal, do not assume foreign income is irrelevant just because it was paid into a foreign bank account.
What Is Anexo J?
Anexo J is the IRS annex used for income obtained outside Portugal.
Portal das Finanças says residents in Portugal who have foreign income should include Anexo J in the Modelo 3 declaration, in addition to the annexes for Portuguese income.
Anexo J may also be relevant for foreign bank or securities accounts. Portal das Finanças says Quadro 11 identifies foreign deposit or securities accounts, even if they did not generate income, when the taxpayer is the holder, beneficiary, or authorized to move those accounts.
This is one of the most common surprises for foreigners.
Examples where Anexo J may matter
| Situation | Why it may matter |
|---|---|
| Salary from a foreign employer | Foreign employment income |
| Pension paid from another country | Foreign pension income |
| Bank interest from Revolut, Wise, Trade Republic, or foreign bank | Foreign capital income or account reporting |
| Dividends from a foreign broker | Foreign investment income |
| Foreign rental income | Foreign property income |
| Foreign tax paid on the same income | Possible double-taxation credit |
| Foreign investment account with no income | Account identification may still be relevant |
This is also where many people make mistakes because investment platforms, foreign banks, and tax forms use different terminology.
Do You Need to Declare Foreign Bank Interest?
If you are tax resident in Portugal, foreign bank interest can be reportable.
Portal das Finanças states that residents with tax domicile in Portugal must declare income obtained in Portugal and abroad, including financial income such as interest or dividends deposited in foreign accounts.
So if you received interest from a foreign bank or investment platform, do not ignore it.
Examples foreigners often ask about:
- Revolut interest
- Wise interest
- Trade Republic interest
- Foreign savings account interest
- Dividends from a broker
- Interest from emergency funds outside Portugal
The amount may be small, but AT may receive information from other tax authorities through international information exchange.
What Is Englobamento?
Englobamento means including certain income in your overall taxable income instead of leaving it taxed separately at a flat/final rate.
Foreigners often see this option in Portal das Finanças and do not know whether to choose yes or no.
It can affect income such as:
- Some interest
- Some dividends
- Some rental income
- Some capital income
- Other income depending on the annex and category
Is englobamento good or bad?
It depends.
Englobamento may help some people and hurt others. It depends on your total income, deductions, tax bracket, income type, withholding already made, and whether the option forces similar income categories to be included together.
Do not choose englobamento only because someone online said it gives a refund.
Use the simulation in Portal das Finanças and compare scenarios where possible. If you have foreign income or several income types, ask an accountant.
IRS Automático: Should Foreigners Use It?
IRS Automático can be useful for simple cases, but foreigners should be careful.
Portal das Finanças says automatic IRS can become definitive if confirmed within the filing period, and for eligible taxpayers the provisional declaration may become definitive at the end of the deadline if no Modelo 3 is submitted.
The risk is that your automatic declaration may not include everything relevant to your situation.
Be careful with IRS Automático if you have:
- Foreign income
- Foreign bank or investment accounts
- Self-employment
- Rental income
- Capital gains
- NHR or another special tax status
- Changed residency during the year
- Married/partner filing questions
- Dependents with foreign income
- AIMA/tax address complications
If the automatic declaration does not match your real tax situation, you may need to submit Modelo 3 manually.
What Are the Main IRS Annexes Foreigners Hear About?
You do not need to memorize every annex, but these are common ones foreigners encounter.
| Annex | Common use |
|---|---|
| Anexo A | Employment income and pensions from Portugal |
| Anexo B | Self-employment/business income under simplified regime or isolated acts |
| Anexo F | Rental income |
| Anexo G | Capital gains and some asset sales |
| Anexo H | Deductions and tax benefits |
| Anexo J | Foreign income and foreign accounts |
| Anexo L | Non-habitual resident or similar special regime information, where applicable |
| Anexo SS | Social Security-related information for some self-employed workers |
Your exact annexes depend on your situation. Do not add an annex only because a blog mentions it; add it because you have the type of income or situation it covers.
e-Fatura: Why Your NIF Matters
When you buy things in Portugal, shops may ask:
“Contribuinte?”
They are asking whether you want your NIF on the invoice.
Invoices with your NIF can feed into e-Fatura, which is used for some IRS deductions.
For foreigners, common mistakes include:
- Not asking for invoices with NIF
- Using the wrong NIF
- Not checking pending invoices
- Not classifying invoices when needed
- Assuming every invoice automatically becomes a deduction
- Forgetting that some deadlines happen before the IRS filing window
e-Fatura does not replace the IRS return. It supports deductions and invoice validation.
Do You Need a Portuguese Bank Account for IRS Refunds?
A Portuguese IBAN can make life easier, but check what Portal das Finanças allows in your situation.
If you expect a refund, make sure your IBAN is correctly registered in Portal das Finanças before submitting. If you owe tax, check payment instructions carefully and pay by the deadline.
Common Mistakes Foreigners Make With IRS
1. Thinking “I already paid tax abroad, so Portugal does not need to know”
If you are tax resident in Portugal, foreign income may still need to be declared. Foreign tax paid may be considered for double-taxation relief, but you normally still declare the income.
2. Forgetting Anexo J for foreign accounts
Even if the account produced little income, Anexo J may still be relevant for foreign deposit or securities accounts.
3. Using IRS Automático without checking foreign income
Automatic IRS may be incomplete for many foreigners.
4. Choosing englobamento without simulation
Englobamento can change the final tax result. Compare carefully.
5. Not updating tax address
If your tax address is wrong, AT may treat your situation incorrectly.
6. Missing the 1 April to 30 June filing window
Late filing can create penalties and stress.
7. Assuming NHR or a special regime means “no IRS return”
Special regimes may change how some income is taxed, but they do not automatically remove the filing obligation.
8. Not keeping documents
Keep salary statements, pension documents, bank interest statements, dividends, tax paid abroad, rental statements, and proof of expenses.
9. Mixing gross and net amounts
Portal das Finanças guidance on foreign income refers to declaring gross income, social security contributions where applicable, and tax paid abroad. Do not randomly use net bank deposits without checking.
10. Trusting informal answers as final tax advice
Informal discussions can help you discover what to ask, but they are not a reliable basis for deciding your tax return.
Practical IRS Checklist for Foreigners
Before filing, collect:
- NIF and Portal das Finanças login
- Current tax address confirmation
- Portuguese salary statements, if employed
- Recibos verdes or self-employment records, if self-employed
- Foreign salary, pension, interest, dividend, rental, or investment statements
- Foreign tax paid documents
- Portuguese rental/property income documents, if relevant
- e-Fatura information
- Health, education, rent, and other deduction evidence
- IBAN for refund/payment setup
- NHR/IFICI or special regime documents, if applicable
- NISS and Social Security information, if self-employed
- Accountant questions list
When Should You Use an Accountant?
Use an accountant if any of these apply:
- You became tax resident during the year
- You moved out of Portugal but your tax address may still be Portuguese
- You have income from another country
- You have foreign bank/broker accounts
- You received dividends, interest, capital gains, crypto, or stock options
- You are self-employed
- You have NHR/IFICI or another special tax status
- You own or rent property in Portugal or abroad
- You are married/partnered and unsure whether to file jointly
- You received an AT warning or mismatch message
- You do not understand which annex applies
A simple Portuguese salary-only return may be manageable. A cross-border return can become risky quickly.
Questions Foreigners Commonly Ask
I moved to Portugal in the middle of the year. Do I file IRS?
Maybe. You need to check whether you became tax resident and what income you received during the relevant period. If you became resident, foreign income after becoming resident may matter. Ask an accountant if the year was split between countries.
I only worked in Portugal for a few months. Do I still need to file?
Possibly. If you earned Portuguese income, you may need to file or may benefit from filing. Check Portal das Finanças and your withholding situation.
I am a student. Do I need to file IRS?
It depends on whether you had income, your residency status, dependents, scholarships, work income, or foreign income. Do not assume student status automatically means no filing.
I received only Portuguese salary. Is IRS Automático enough?
Maybe, if your situation is simple and all data is correct. Still check your household, address, deductions, IBAN, and withholding.
I have Revolut, Wise, Trade Republic, or a foreign broker. Does it matter?
If you are tax resident in Portugal, foreign bank/broker accounts and income can matter, especially for Anexo J. Check your statements and ask an accountant if unsure.
I paid tax in another country. Will Portugal tax me again?
Foreign tax paid may be considered for a double-taxation credit depending on the income, country, and treaty situation. You generally need to declare the income and the foreign tax paid correctly.
Should I choose englobamento?
There is no universal answer. Simulate both options where possible and ask an accountant if foreign income or multiple income types are involved.
What happens if I do not file?
If you are required to file and do not, AT may notify you, assess tax based on available information, and apply penalties or interest. It is better to correct problems voluntarily as early as possible.
Summary
IRS in Portugal is not only for Portuguese citizens. Foreigners may need to file if they are tax resident in Portugal or if they earn Portuguese-source income as non-residents.
The most important first steps are to check your tax residency, confirm your tax address, collect income documents, and understand whether foreign income or Anexo J applies. If your case is simple, Portal das Finanças may be manageable. If you have foreign income, foreign accounts, self-employment, investments, NHR/IFICI, or cross-border tax questions, professional help is usually worth it.
