IRS 2024 archive: returns filed in 2025
The Modelo 3 return for 2024 income had to be filed between 1 April and 30 June 2025. Residence for 2024 followed from more than 183 days in Portugal in any 12-month period beginning or ending in 2024, or from a home there suggesting an intention to keep it as a habitual residence. Residents had to declare worldwide income, with foreign income in Anexo J.
How expats file the 2024 Portugal IRS return (Modelo 3)
This is a practical guide to filing your 2024 Portuguese IRS return (Modelo 3) as an expat. It covers deadlines, residency rules, income categories, key regimes, deductions, and the most common filing mistakes in cross-border cases.
This archive records that campaign; it is not a current filing calendar.

Key dates for 2024 IRS filing
The normal filing window for 2024 income ran from 1 April to 30 June 2025. Household updates and invoice validation had the deadlines published by AT for that filing campaign.
Missing e-Fatura validation did not make every deduction irrecoverable: qualifying health, education, housing and care-home expenses could be substituted in Anexo H with supporting records. General household expenses and the VAT benefit had a separate complaint route. These were 2025 campaign procedures; an available correction or challenge for a 2024 return or assessment now depends on its status and the applicable deadline.
Who needs to file
Your filing obligation depends on your tax residency status for 2024:
- For 2024, test more than 183 days in any 12-month period beginning or ending in that year, or the statutory habitual-home condition. Count presence days that include an overnight stay.
- Non-residents: File only to declare Portugal-sourced income (salary from a Portuguese employer, rental income from Portuguese property) unless it was fully covered by final withholding tax.
The most common residency mistake is failing to recognise that you became a Portuguese tax resident mid-year.
Income categories: A through H
Portugal classifies income into categories that determine how each type is taxed:
- Category A: Employment income.
- Category B: Self-employment, freelance, and business income.
- Category E: Capital income (dividends, interest).
- Category F: Rental income.
- Category G: Capital gains (property, shares, crypto).
- Category H: Pensions.
Most resident income is aggregated (englobamento) and taxed at progressive rates, though specific flat-rate options exist for certain Category E and G income.
Key regimes affecting your 2024 return
NHR transition
The 2024 State Budget law revoked the NHR regime from 1 January 2024, subject to transitional rules. Existing holders continue through their 10-year term. People resident on 31 December 2023 could still register for 2023 by 31 March 2024.
People who became resident in 2024 could register for 2024 by 31 March 2025 if they held one of the listed elements dated by 10 October 2023 or 31 December 2023. A later request, if approved, applies from the request year until 2033.
For details, see our NHR overview guide.
IRS Jovem (youth IRS)
For 2024 income, IRS Jovem covered the first five years of Category A and B income after completion of a level 4 or higher course, subject to the other requirements. Entry was between ages 18 and 26, extended to 30 for a doctorate; the age-35 limit concerned continuation of an existing benefit. The broader rules for 2025 income do not apply retrospectively to 2024.
Programa Regressar (ex-resident regime)
Offers a 50% income exclusion on Category A and B income for qualifying returning Portuguese residents.
Simplified regime (category B)
Under the self-employed simplified-regime rules, the simplified regime applies, unless organised accounts are elected, where gross Category B income in the immediately preceding tax year did not exceed EUR 200,000. A 0.75 coefficient applies to listed professional activities, subject to expense-substantiation rules; other activities can use different coefficients.
Crypto asset taxation
For 2024, qualifying crypto gains on assets held under 365 days are generally taxed at 28%, with optional aggregation in ordinary cases. Where statutory conditions are met, qualifying crypto gains on assets held at least 365 days may be excluded under the crypto-asset capital-gains rules. Securities, electronic money, certain exchanges, source rules, and listed-jurisdiction conditions can prevent the exclusion. Income from staking or mining may fall under Category B or E.
Portuguese tax deductions for 2024
Deductions reduce your final tax liability (the coleta). The main categories:
- Dependants and ascendants: Fixed amounts per qualifying family member.
- General family expenses: Broad expenses validated via e-Fatura, capped per taxpayer.
- Health costs: Eligible medical expenses with specific VAT rates or doctor's prescription.
- Education and training: Tuition, books, and qualifying student rent.
- Housing costs: Eligible rent (from registered contracts) or pre-2012 mortgage interest.
- Care home costs: Expenses for eligible nursing or elderly care facilities.
- VAT deduction (e-Fatura): Partial VAT refund on invoices from specific sectors (restaurants, hairdressers, auto repair, transport, gyms, veterinary).
- Fiscal benefits (EBF): Qualifying donations, PPR (pension savings plan) contributions, and similar items under the Tax Benefits Code.
Most deductions depend on invoices being associated with your NIF and validated on e-Fatura. An overall income-based cap limits the total deduction amount.
Common filing mistakes
These are the most common errors in expat IRS filings:
- Residency misclassification. Filing as non-resident when residency criteria are met, or vice versa. This changes your entire income scope.
- Omitting worldwide income. Forgetting to declare foreign income (dividends, pensions, rental income from abroad) when filing as a resident. This requires Anexo J.
- e-Fatura neglect. Missing validation deadlines or failing to request NIF on invoices throughout the year.
- Wrong freelance activity codes. Incorrect CAE codes or misapplied Simplified Regime coefficients.
- Rental income omission. Particularly income from platforms like Airbnb, which is reportable.
- Crypto reporting gaps. Inaccurate reporting of short-term gains or failure to report taxable transactions.
- NHR treatment applied incorrectly. Claiming NHR benefits without confirming current-year eligibility or regime status.
- Treaty benefit errors. Incorrectly applying double taxation treaty provisions without supporting documentation or procedural compliance.
- Incorrect dependant claims. Claiming deductions for dependants or ascendants without meeting the strict legal criteria for cohabitation and income thresholds.
Modelo 3 filing: step by step
The practical filing sequence for cross-border cases:
- Confirm residency status. Determine whether you are filing as resident or non-resident for 2024.
- Inventory all income sources. Map every income source by Portuguese category (A through H) and by jurisdiction.
- Review e-Fatura and household data. These had pre-filing deadlines in the 2025 campaign.
- Determine regime treatment.
- Prepare supporting documents. Foreign income certificates, withholding statements, prior-year filings.
- Complete the appropriate annexes. Anexo A (employment), Anexo B (self-employment), Anexo J (foreign income), Anexo L (special regimes), and others as applicable.
Reviewing a 2024 return

Frequently asked questions
When is the IRS filing deadline for 2024 income?
The normal Modelo 3 filing window for 2024 income ran from 1 April to 30 June 2025.
Do I need to file if I only have Portuguese employment income?
If your profile is straightforward, you may qualify for IRS automático (automatic filing). Check the Portal das Finanças to see if a pre-filled return is available. If you have any additional income sources or deductions beyond the automatic calculation, manual filing is required.
What happens if I file late?
Late filing can lead to a fine, subject to the rules on waiver or reduction. Interest is separate: compensatory interest can apply when a delay attributable to you holds up the assessment of tax due, and late-payment interest applies if tax is not paid by its deadline.
Can I file jointly with my spouse?
Yes, if both spouses are tax residents.
Do I need to report crypto holdings or just transactions?
For the 2024 income return filed in 2025, report the relevant crypto disposals even where no tax is due. Qualifying non-security crypto disposals held for at least 365 days belong in Anexo G1; taxable disposals use the applicable gains annex.
What is Anexo J and who needs to file it?
Anexo J is the annex used to declare foreign income. Portuguese tax residents who have income from outside Portugal (dividends, pensions, rental income from abroad) must file it.
