Q: How do you handle foreign income?

Foreign income is the core of what we do. We ask about each source — salary, pension, dividends, interest, capital gains — and prepare the right annex (typically Anexo J) with the right categories. Portuguese salary and other AT-provided values stay as the portal has them.

Answer up to 15 guided questions about your year — foreign income, NHR or IFICI, foreign accounts. Simples figures out the right annexes, prefills your declaration, and walks you through submitting in Portal das Finanças.

Testimonials

What expats say about Simples.

Quick honest takes from early users — what worked, what didn't, what surprised them.

"Honestly the first time I understood what my Anexo J actually said. Two minutes and I knew which forms applied — without typing a single euro figure."

Marta K.

Remote developer · Lisbon

"Paid €520 last year for what felt like an hour of work. The free check told me my case was supported. The €49 vs €500 math wrote itself."

James D.

NHR · Cascais

"I've been dreading IRS for three years. This was the first tool that didn't make me feel stupid for not speaking Portuguese."

Priya R.

Designer · Porto

"The fact that Simples won't even let me pay if my case is too complex — that's what made me trust it."

Aleksandr S.

Investor · Almada

"I ran the check, saw which annexes I needed, and then went into the portal already knowing what to look for. Game changer."

Lucía M.

Pension · Lagos

"The English explanations for the Portuguese codes were the killer feature. I finally understood why my accountant was charging €600."

Tomás B.

Freelancer · Lisbon

"Refreshing to use a tax tool that doesn't try to upsell me on insurance, crypto, or whatever else. Just taxes."

Eva V.

IFICI · Aveiro

"Two minutes of questions, then a clear next step. That's all I needed. I came back the next morning to actually file."

Rafa H.

Brokerage · Setúbal

"I was about to pay €399 to AnchorLess. Found Simples, did the check, did the filing myself. Saved €350 and learned how my taxes actually work."

Chen H.

NHR · Lisbon

"Loved that the assessment told me upfront 'we don't handle US filing'. Saved me from finding out after I'd already paid."

Jenny W.

US citizen · Lisbon

"Refreshingly honest. No 'AI tax magic'. Just clear questions, clear answers, and a file I could actually verify before I submitted it."

Niels K.

Investments · Funchal

"The 'review every value in English' step is what got me. I've filed three times before and never knew what half of those numbers were."

Sofia F.

Remote · Braga

FAQ

Honest answers to recurring questions.

Does Simples submit my declaration for me?

No. Simples prepares the file and the English review guide. You log into Portal das Finanças, review every value, and click the final submit button yourself.

Is Simples a replacement for an accountant?

No. Simples is a filing-preparation tool, not an accountant. For most expats with foreign income, investments, NHR or IFICI, it's everything you need. For cases we don't cover — joint filing, dependents, rental income, self-employment — the free check tells you upfront and connects you to a certified accountant.

How do you handle foreign income?

Foreign income is the core of what we do. We ask you about each source — salary, pension, dividends, interest, capital gains — and prepare the right annex (typically Anexo J) with the right categories. Portuguese salary and other AT-provided values stay as the portal already has them.

Do you support self-employment or recibos verdes?

Not yet. Self-employed income (recibos verdes, simplified regime, business income) is a different return path with its own annexes. The free check flags it and connects you with a qualified accountant who specialises in freelancer filings.

How does Simples handle my Portuguese salary?

It doesn't ask you to retype it. Portuguese salary, withholding, Social Security and most rent-deduction values come from the tax authority's pre-filled declaration. Simples focuses on the parts that aren't already there — foreign income, NHR/IFICI, foreign accounts.

Does Simples handle NHR or IFICI?

Yes — both regimes, including the foreign-income tax method choices that come with them. Regime-specific values and high-value-activity classifications are flagged for your review in the portal.

Do you store my tax-portal password?

No. We never ask for it. You log into Portal das Finanças yourself, in your own browser, and stay there for review and submission.

What if my situation isn't covered?

The free check tells you so before payment. If we don't cover your case, we either put you on a profile-specific waitlist or connect you with a qualified accountant who handles your case type.
