Spain taxes for American retirees start on a specific day: the 184th day you spend in Spain in a calendar year. From then on you’re a Spanish tax resident, Spain taxes your worldwide income, and you file two returns every year, one in each country, for as long as you live there.
None of this is a reason not to come. For a typical retiree income the Spanish bill is real money, not confiscation. But it’s the part of the move that costs people the most when it’s ignored, and it’s worth one paid hour with a cross-border adviser before you book a flight.
Here’s how it works, checked against Spain’s tax agency in September 2026.
How residency arrives
You’re a Spanish tax resident if any of these is true:
- you spend more than 183 days in Spain in a calendar year (the days don’t have to be consecutive),
- Spain is the center of your economic interests,
- your spouse and minor children habitually live in Spain.
There’s no split year. If you’re resident, the whole calendar year is Spanish, including the months before you arrived. So the cheapest tax planning you’ll ever do is the date on your one-way ticket. From 1 July to 31 December is 184 days, one too many. Arrive on 2 July or later and you can stay under the day count for that year; arrive in May and the whole year may be Spanish.
And note the collision with the visa. Spain’s retirement visa now requires more than 183 days a year in Spain to renew. You can’t hold the residency and avoid the tax residency. Anyone selling a structure that promises both is selling audit risk.
What Spain taxes, and how
Spain splits income into two piles and taxes them differently.
The general pile: pensions, Social Security, IRA and 401(k) withdrawals, rental income, wages. It’s taxed on a progressive scale, half national and half regional, so your region changes the rate.
The savings pile: interest, dividends and capital gains. It’s taxed on its own national scale, the same in every region:
| Savings income | Rate |
|---|---|
| Up to €6,000 | 19% |
| €6,000 to €50,000 | 21% |
| €50,000 to €200,000 | 23% |
| €200,000 to €300,000 | 27% |
| Above €300,000 | 30% |
For a retiree with around €35,000 of pension income, the effective rate on the general pile lands around 15–19%, and lower from 65 and 75, when age allowances rise. The headline top rates only bite on very large incomes: above €300,000 the combined rate is 45% in Madrid, 47% in Andalusia, 50% in Catalonia and 54% in Valencia, the highest in Spain. Most retirees never get close.
Social Security, pensions and IRAs
This is the question I get most, and it’s where the internet disagrees with itself. Spain’s tax agency answers it directly:
- US Social Security and private pensions are taxed in Spain under Article 20 of the US–Spain treaty. If the US also taxes the benefit, Spain gives a deduction for the double taxation, unless the US tax is based only on your citizenship.
- US government pensions (federal civil service, military, state and local government) are generally taxed only in the US. Spain exempts them but counts them when it sets the rate on your other income.
- IRA and 401(k) withdrawals follow the private-pension rule and are generally taxed in Spain as a resident. Lump sums and Roth accounts are where the two systems disagree most, so get advice before you take one.
On the US side nothing stops. You file Form 1040 every year, as every American abroad does. The foreign earned income exclusion only covers wages and self-employment income, not pensions or Social Security, so retirees rely on the treaty and foreign tax credits. You’ll want a US preparer who does expat returns and a Spanish gestor, and you’ll want them to talk to each other.
Modelo 720: the form about your American money
If Spain is your tax residence and you hold more than €50,000 abroad in any one category — bank accounts, securities and insurance, or real estate, each tested separately — you file Modelo 720 between January 1 and March 31. It’s informational. It usually costs nothing. It’s mandatory.
Read that against an ordinary American retiree’s balance sheet: a brokerage account, an IRA, a house not yet sold. Nearly every American resident in Spain crosses one of those lines in year one. The old penalties were so severe that the EU’s highest court struck them down in 2022; the current ones are milder, but still real. Nobody official will remind you to file. The gestor who does your Spanish return should ask; if they don’t, ask them.
It mirrors in the other direction. The US wants an FBAR when your foreign accounts total more than $10,000 at any point in the year, and Form 8938 above higher thresholds: for someone living abroad, $200,000 at year end or $300,000 at any point if single, double that if married filing jointly. Three reports, three thresholds, none replaces another.
Wealth tax: where the region matters most
Spain has an annual tax on net worth, and here the regions don’t just adjust the rate, they decide whether it exists.
| Region | Wealth tax in 2026 |
|---|---|
| National rule | Applies above €700,000 per person, plus up to €300,000 for your main home |
| Madrid | 100% rebate: effectively zero |
| Andalusia | 100% rebate: effectively zero |
| Valencia | Personal exemption raised to €1,000,000 |
| Catalonia | Applies from €500,000 |
Above roughly €3.7 million of net worth, a national solidarity tax applies even in the rebate regions. Below that line, a couple who sold an American house into a portfolio can owe thousands a year in Barcelona and nothing in Málaga. Choose the region with this table open, not after you’ve signed a lease.
The Beckham Law is not for retirees
Someone will mention it at dinner. The special regime taxes new arrivals at a flat 24% on up to €600,000 of work income, for the year you arrive and five more. It’s for people who come to work: employees, remote workers for foreign employers, certain entrepreneurs. You have to choose it within six months of registering with Spanish social security. If you’re retired, it doesn’t apply to you.
Two things that cost more than the tax
Spanish investment funds. To the IRS, most non-US funds are PFICs, and the reporting and tax treatment are punitive. The friendly bank manager’s recommendation can cost more than the branch. Keep US-domiciled holdings until someone qualified says otherwise.
Leaving without telling anyone. If you move away, tell the tax agency on form 030 within three months, or it can keep treating you as resident.
Every spring, in one list
- Spanish income tax return, through a gestor (roughly €100–400 a year).
- Modelo 720 by March 31, if any category abroad is over €50,000.
- US Form 1040, through a preparer who handles expat returns.
- FBAR, and Form 8938 if you cross its threshold.
Handled like this, Spanish taxes are a known, moderate, annual bill. Ignored, they end Spanish chapters in an office nobody knew existed. I’m not a tax adviser, and nothing here replaces one: it’s the map that makes your hour with one productive.
