Why Simples

The portal is in Portuguese. Your tax life isn't.

Three things keep most English-speaking expats stuck in the same loop every spring.

01

The tax portal is in Portuguese. Your tax life isn't.

Dense legal language, codes without context, fields you can't tell apart. You close the tab.

02

€400–€600 feels wrong for a typical year.

Most accountants don't price-split an ordinary expat year from a genuinely complex case.

03

You want to see every value before you submit.

Filing is high-trust. You don't want a black box — you want to understand what's going in.

How it works

First, keep the Portal data. Then fill only what's missing.

The launch flow starts from the official pre-filled declaration, so salary, rent deductions, and other AT data stay intact.

01

Answer annex-routing questions in English.

Only the classifiers: income categories, residency, household, foreign accounts, NHR/IFICI. No NIF, bank details, or salary amounts.

Between the calculator and the €500 accountant.

Trust

What Simples does, and doesn't.

High-trust products earn that trust by being clear about their limits. Here are ours, in writing.

Simples does this

  • Asks plain-English questions to understand your situation
  • Shows your likely Modelo 3 annexes from classification questions
  • Starts the paid flow from the Portal pre-filled declaration
  • Preserves salary, rent deductions, and other AT-provided values
  • Explains what to review before you submit
  • Flags anything that warrants a second pair of eyes

Simples doesn't this

  • Submit your declaration — you click the final button, in the portal
  • Store your tax portal credentials
  • Give professional tax, legal, financial, or accounting advice
  • Replace a certified accountant for complex situations
  • Guarantee tax savings, acceptance, or correctness
  • Process cases outside its supported scope
FAQ

Honest answers to recurring questions.

Does Simples submit my declaration for me?
No. Simples prepares the file and guide. You stay in control — you review the Portal result and click the final submit button yourself.
Is Simples a replacement for an accountant?
No. Simples is a tax-filing tool, not an accountant. For most expats with foreign income, investments, NHR, and Portuguese salary, it's everything you need. If your year includes things like joint filing, dependents, rental income, or self-employment, Simples tells you upfront and points you to one.
What does "ready to file" actually mean?
For launch, it means you start from the Portal pre-filled declaration, Simples fills the missing supported annexes, and you re-upload the updated file. The portal is always the final source of truth.
How does Simples handle my Portuguese salary?
It doesn't ask you to retype it. Portuguese salary, withholding, Social Security, rent deductions, and many other values should come from the tax authority's pre-filled data. Simples focuses on the parts that are missing or need routing.
What about NHR or the new IFICI regime?
Simples handles both, including the foreign-income tax method choices that come with them. Regime-specific values and high-value-activity classifications are flagged for your review — those are the fields worth double-checking in the portal.
Do you store my tax portal password?
No. We never ask for it. Simples runs the intake and produces your declaration; you log into the portal yourself, in your own browser, and stay logged in there for review and submission.
What if my situation isn't covered?
The free intake tells you so before payment. Most expats fit — if you don't, we'll either put you on a profile-specific waitlist or point you to a qualified accountant who handles your case type.
