How it works

IRS in 3 steps — from start to submission receipt.

No installs, no files to download. Everything happens in your browser.

  1. Get your data into FIZ 01

    Your Portuguese tax data and deductions.

    Your Portuguese tax data and every deduction (medical, education, gym, household maintenance, restaurants, etc.) — straight into FIZ. Pick how:

    • Connect to the AT. Use your NIF and Portal das Finanças password to grant FIZ access — transmitted over an encrypted channel (TLS) and stored at rest with AES-256-GCM, never in plain text. Everything imported in seconds.
    • or Enter your data yourself. Same wizard, slower.
    Same wizard, same simulation — either way.
  2. Prefill + wizard 02

    We prefill from the AT and fill in what the AT doesn’t know

    The wizard uses what the AT already has and walks you through what’s missing — in English or Portuguese, no jargon.

    • From the AT. Income, withholdings, deductions, issued recibos verdes and household — imported directly.
    • What’s missing. Foreign income with credit for tax paid abroad, self-employed expense categorization, joint filing. For NHR / IFICI / IRS Jovem you confirm eligibility and we apply the reduced rates.
    Every field explained
  3. See the result — then choose 03

    The calculation is free. €49.99 only when you submit.

    Refund or amount owed — calculated to the cent and validated by the AT, before you pay anything. Pick how to submit:

    • File directly through FIZ. We submit Modelo 3 to the AT and email you the receipt.
    • or Download the XML. Upload it to Portal das Finanças and submit there.
    Don’t like the number? No payment, no commitment.

What you can declare

Every type of income — earned in Portugal or abroad.

If you made money in 2025, it falls into one of these — same filing, same price.

  • Salary

    Whether you worked for a Portuguese company or a foreign one — both go in the same filing.

  • Self-employed income

    If you invoice clients yourself — Portuguese clients, foreign clients, or both. We import your invoices, apply the right tax treatment based on what you do, and let you classify business expenses one by one.

  • Renting out property

    A flat in Lisbon, a house in Spain, both — we declare the income and compute both tax options (aggregated with your other income, or flat rate) so you pay the lower one.

  • Dividends and interest

    From a Portuguese bank, a Portuguese broker, a foreign broker (Interactive Brokers, Degiro, eToro), or a foreign bank account — each declared with the right tax treatment and foreign credit.

  • Other foreign income

    Royalties, alimony received from abroad, occasional foreign earnings — covered.

Plus, if it applies to you:

Special regimes that reduce your tax — applied automatically.

  • Joint filing

    Joint and separate computed — you keep the better outcome.

  • NHR

    Non-Habitual Resident — reduced rates applied automatically on eligible income.

  • IFICI NEW

    The new framework for skilled professionals — same automatic treatment.

  • IRS Jovem

    Exemptions for young workers in the first years of activity.

Tax-speak: FIZ covers Anexos A, B, E, F, J and L — mapped to your situation automatically.

Included

Everything included for €49.99

One-off payment, no subscription. One price per filing — regardless of which income types you have.

  • From the AT

    Official prefill

    We import income, withholdings, issued recibos verdes and deductions already reported to the AT (Autoridade Tributária — Portugal’s tax authority).

  • All income types

    Salary, self-employed, rental, foreign, dividends and interest

    Employment, self-employed, rental, dividends, interest, NHR / IFICI and foreign income. You can combine several situations in the same filing.

  • Anexo B

    Right coefficient in regime simplificado

    You enter your CIRS code and we apply the right coefficient (0.75 / 0.35 / 0.10) when computing taxable income. End of the “what percentage counts as income” doubt.

  • Before submitting

    Tax simulation

    We simulate the settlement before filing — you see exactly what you’ll pay or get back.

  • Official filing

    Secure submission to the AT

    We file Modelo 3 directly on the Portal das Finanças. Submission number and XML copy emailed in seconds.

  • Before, during, after

    Email support

    Real humans reply — in English or Portuguese — in under 24 hours.

Security

Your AT password is in safe hands.

We know trusting your Portal das Finanças password to an online service makes you think. That’s why we encrypt it with AES-256-GCM — the same standard European banks use — and only decrypt it for an instant, at the exact moment we log in to the AT on your behalf.

  • AES-256-GCM encryption at rest

    Your password is never stored in plain text.

  • Used only to log in to the AT on your behalf

    Decrypted only at the moment of login. Never shared with third parties.

  • Revoke and delete at any time

    From your account settings. GDPR applies.

Pricing

Simple pricing. No subscription.

Pay once, when you’re ready to submit. We don’t charge to try.

And after

When you need more, Fiz already has it.

Today you came to file IRS — great. If you’re self-employed, IRS is only one of your obligations. When you need the others, they’re all in the same Fiz: same account, same AT session, same support team. No tool-switching.

  • Issue recibos verdes

    Fatura-recibos in seconds, with the right date, client, currency and IVA category. Automatically imported into next year’s IRS.

  • IVA periódica and recapitulativa

    We generate your periódica (monthly or quarterly) and recapitulativa from the recibos you issue — including the zero recapitulativa.

  • Quarterly Segurança Social declaration

    We calculate your contribution based on your relevância and file on time. We remind you when it’s due.

Each service is priced separately from IRS. Start with one, add the others when you need them.

FAQ

Frequently asked questions

  • I’m self-employed (recibos verdes). Does Fiz IRS support Anexo B?

    Yes — fully. We import the recibos you’ve issued, pick the right regime-simplificado coefficient (0.75 / 0.35 / 0.10) based on your CIRS and explain the choice. If you have category B expenses (part of a rent, equipment, software), we classify each one. All in the same €49.99 price.

  • Does Fiz only do IRS, or also recibos verdes and IVA?

    It does everything, but the services are separate — you pay only for what you use. Today you can sign up for IRS at €49.99. If you later need to issue recibos, file IVA periódica/recapitulativa or the quarterly Segurança Social declaration, those services live in the same Fiz account, each with its own price.

  • I have foreign income. What does Fiz IRS cover?

    We cover Anexo J — foreign-sourced income only: foreign salary, foreign pension, interest and dividends from foreign sources, freelance work with foreign clients, rental from property abroad and capital gains earned abroad. For each item you pick the country, the type and the tax already paid abroad; the system computes the foreign-tax credit and shows it in the simulation before submission. (Portuguese-source capital gains and pensions are not covered at this time.)

  • I have NHR / IFICI. Does Fiz IRS support it?

    Yes. We automatically apply the reduced rates and frameworks for eligible income. If you’re unsure whether a specific income qualifies, leave a note in the wizard — our team reviews before submission.

  • Can I file jointly with my spouse?

    Yes. We support joint filing — during the wizard you pick joint or separate and the tax is computed accordingly. The AT submission includes the spouse on the same filing.

  • I have several income sources (salary + recibos + a foreign client). Does it all fit in one filing?

    It does. IRS is one filing with multiple anexos. If you have employment, recibos and foreign clients, you’ll have Anexo A + Anexo B + Anexo J — all produced in the same wizard, at the same price.

  • I already use Portal das Finanças myself. How is this different?

    Technically the result is the same — we file your Modelo 3 with the AT. We change the path: each field explained in plain English, real-time validation, simulation before filing and a stored receipt. Fewer clicks, zero confusing screens.

  • When can I file IRS 2025?

    From April 1 to June 30, 2026. We recommend not waiting until the last week — submitting earlier also means getting your refund earlier, if applicable.

  • What happens to my Portal das Finanças password?

    It is encrypted with AES-256-GCM as soon as we receive it. It is only decrypted for an instant, on the server, when we log in to the AT to file your declaration. We share it with no one and you can request its deletion at any time.

  • What if I usually log in with Cartão de Cidadão or Chave Móvel Digital?

    FIZ connects to the AT using your NIF and Portal das Finanças password. If you usually log in with Cartão de Cidadão or Chave Móvel Digital and don’t remember your password, you can set or reset it on the Portal das Finanças — takes a minute. Or skip the connection and fill the wizard manually.

  • What if the AT rejects my filing?

    We validate the data before submission and simulate the settlement. If it’s still rejected for reasons attributable to the service, we refund the €49.99 paid.

  • Which Modelo 3 anexos are supported?

    Anexos A (employment), B (self-employed / recibos verdes), E (capital — dividends and interest), F (rental), J (foreign) and L (non-habitual resident / IFICI). The face of the declaration is fully covered. You can have several anexos in the same filing — all at the same price.

IRS closes on June 30. Be 5 minutes from a submission receipt.

File early, get your refund earlier. No installs, no subscription.
