Taxes in Spain: the expat basics

Spain taxes residents on worldwide income, Catalonia adds its own rates on top, and the system is enforced with more enthusiasm than Portugal's. None of it is unmanageable — but three things (the Beckham window, the autónomo quota system, and the modelo 720) punish people who learn about them late.

When you become tax-resident

More than 183 days in Spain in a calendar year — or your "centre of economic interests" being here — makes you tax-resident. Days don't need to be consecutive, and sporadic absences count toward the 183 unless you prove residency elsewhere. From that point Spain taxes your worldwide income. The tax year is the calendar year; the annual return (la renta) is filed April to June.

What you'll pay

IRPF (income tax) is progressive and split between state and region — in Catalonia the combined rates run from about 20% at the bottom to roughly 50% on income over €300k. Savings income (dividends, interest, capital gains) is taxed on its own scale, about 19–28%. Employees have withholding from payroll; the renta is mostly a reconciliation.

The Beckham regime — the window that closes

The régimen de impatriados ("Beckham law") lets qualifying new arrivals be taxed as non-residents for 6 years: a flat 24% on Spanish employment income up to €600k, with most foreign income left outside Spanish tax (foreign dividends and gains excepted from the exemption — get advice on your portfolio). Since the startup law, it covers not just transferred employees but remote workers on the digital nomad visa. The catches: you must apply within 6 months of registering with social security, you can't have been Spanish-resident in the previous 5 years, and ordinary autónomos generally don't qualify. If you might be eligible, this is worth tens of thousands of euros — and the deadline does not bend.

Autónomos: the quota system

Freelancers register with both Hacienda (the tax office) and RETA (social security). Two numbers run your life:

• The cuota — monthly social security, now income-based: roughly €200–590/month depending on your real earnings bracket. New autónomos get the tarifa plana: ~€80/month for the first 12 months (extendable a second year on low income).
• IVA and retenciones — 21% VAT charged from your first invoice (Spain has no small-trader exemption threshold like Portugal's), filed quarterly (modelo 303), plus quarterly income-tax prepayments (modelo 130) unless your clients withhold for you.

A gestor (€60–150/month) handles registration, the quarterly carousel, and the renta. In Spain this isn't a luxury; the quarterly system is genuinely hostile to DIY newcomers.

The modelo 720 — read this twice

Tax residents must declare foreign assets over €50,000 per category (accounts, investments, property) on the modelo 720 each spring. It's informational — no tax due — but late or missed filings carry fines that remain nasty even after the EU forced Spain to soften them. If you keep accounts or a flat back home, this form is not optional and your gestor needs to know about it in year one.

Catalonia extras

Catalonia levies a wealth tax on net assets above €500k (with a €300k main-home allowance) — relevant if you're arriving with property or a portfolio. There's also a modest regional inheritance/gift tax regime. None of this should scare you off; all of it belongs in the "ask an advisor before becoming resident" pile, because some planning only works before the 183 days.

What to actually do

1. Before residency: check Beckham eligibility and whether your investments need restructuring — both are use-it-or-lose-it.
2. On arrival: if employed, confirm your employer files the Beckham application in time; if freelancing, register properly and take the tarifa plana.
3. Year one: hire a gestor, calendar the quarterlies, and flag every foreign account for the 720.
4. Every spring: file the renta April–June. The draft (borrador) the system pre-fills is a starting point, not the answer — especially with foreign income in the mix.
