A clear, practical guide to U.S. tax obligations for Americans living in Spain. The United States taxes its citizens on worldwide income wherever they live, and moving to Spain does not change that. This section explains what Americans in Spain may still have to file each year: the federal return, the FBAR for foreign accounts above the threshold, Form 8938 under FATCA, and Form 2555 or Form 1116 depending on whether the foreign earned income exclusion or the foreign tax credit works better in your case. We explain how the U.S.-Spain tax treaty reduces double taxation without eliminating it, and where the totalization agreement on Social Security fits.
We also cover the Spanish side that interacts with your U.S. filings: becoming a Spanish tax resident once you spend more than 183 days in Spain in a calendar year, the Modelo 720 declaration of foreign assets, wealth tax and the regional differences, the Beckham regime for new arrivals, U.S. retirement accounts seen from Spain, selling a U.S. home after the move, and breaking state tax residency before you leave.
Who files a first Spanish income tax return, the 15,876 euro limit for U.S. pay, Renta WEB access, rates, joint filing, dollar conversion, the double taxation deduction and where U.S. income goes.
The U.S. side of life in Spain: Form 1040 deadlines abroad, the FBAR and Form 8938, the exclusion or the credit, Spanish funds, the treaty and a nonresident spouse, beside the Spanish dates.
The Streamlined Foreign Offshore Procedures let Americans in Spain file three years of returns and six years of FBARs without penalties. Eligibility turns on 330 days abroad, and the window moves.
Payments continue for U.S. citizens in Spain and can land in a Spanish euro account. Spain taxes the benefit and deducts the U.S. tax, and the 1986 agreement still governs totalization.
Once you are a Spanish tax resident, the treaty hands your 401(k) and IRA withdrawals to Spain. The United States taxes you anyway and credits the Spanish tax; a personal IRA's Spanish class is open.
Who files Modelo 720, the three 50,000 euro blocks, the March 31 deadline, how U.S. accounts, IRAs, a 401(k), a house, an LLC or a trust land on it, the fines since 2022, and Modelo 721 for crypto.
Federal tax follows your citizenship to Spain. State tax follows your domicile, and California and New York keep former residents on the books unless the move is documented. What each state tests.
Sell in a year when you are not a Spanish tax resident and only the IRS looks at the gain. Sell in a year when you are, and Spain taxes it too, with a U.S. tax credit. The dates decide the bill.
The renunciation declared at the Spanish oath, why U.S. law presumes you keep your citizenship, the passport rule that meets Spain's three-year clause, and formal renunciation.
A wire funded from your U.S. bank account is outside the 1 percent remittance tax. The exchange-rate margin is the cost that matters, and Spain declares cash, not wires, from 10,000 euros.
Who qualifies after 5 years of non-residence, what the 24 percent rate covers, the 6-month Modelo 149 deadline, your spouse and children, and what the regime changes for an American's filings.
Your broker's policy decides what you can still buy, the PFIC rules make a European fund an expensive fix, and Spain reports the account on Modelo 720 and counts it for the wealth tax.
The costly mistakes after a move to Spain come from rules that apply on a date. Eight of them, from tax residency to the padrón, with the official rule and the fix.
Name certificate, NIEs, deed and registry with their deadlines and fee caps, the 2026 corporate tax rates, RETA for directors, permits, and the IRS forms an American owner files.
Living in Spain does not change your answer on a Spanish bank's FATCA form. What the self-certification asks, what the bank reports, and how the police certificate of non-residence works.
Which permits allow it, when U.S. clients pay Spanish VAT, the invoice and Modelo 303 boxes, Modelo 130 without withholding, the certificate that ends U.S. self-employment tax, and the U.S. forms.
The 183-day and economic-interest tests, the Agencia Tributaria certificate and its Basque and Navarra equivalents, Form 6166, and why a Spanish certificate never ends U.S. tax for a citizen.
