Practical guidance on Spanish tax residency, the US–Spain double tax treaty, Modelo 720 asset reporting, and the Beckham Law — tailored for Americans who have moved from Miami to Costa Brava.
Why Costa Brava
The Costa Brava, Cataluña's rugged northern coast, combines dramatic cliffs, medieval villages, excellent local cuisine, and relative proximity to Barcelona and France, appealing to Americans who want sophistication without the urban intensity.
Americans from Miami — many of them real estate, finance, and Latin-connected professionals — are increasingly discovering Costa Brava as an ideal base in Europe. The reasons are partly lifestyle and partly financial: existing cultural ties to Spain, EU market access, and favourable tax treaties.
As part of Cataluña, the Costa Brava falls under Cataluña's regional tax rates, which are higher than regions like Madrid or Andalucía. However, the Beckham Law regime can substantially mitigate this for qualifying residents.
From a tax perspective, the move from Miami to Costa Brava requires careful advance planning. As a US citizen you remain subject to US worldwide taxation regardless of where you live — but a well-structured Spanish residency can use the US–Spain Double Tax Treaty to dramatically reduce double taxation on your investment income, employment income, and pension distributions.
Towns like Cadaqués, Begur, and Llafranc attract discerning buyers; property is highly sought after and supply is constrained by coastal protection laws. US buyers should be aware of the Impuesto de Transmisiones Patrimoniales (ITP — transfer tax) of between 6% and 11% depending on the autonomous community, in addition to any notary and registration costs.
Spain's top marginal income tax rate sits at around 47% for very high earners. However, the Beckham Law flat rate of 24% on Spanish-source income and the Digital Nomad Visa's special regime can dramatically improve this for qualifying US professionals. When combined with the US–Spain treaty's provisions, the effective tax rate on many income streams can be brought well below what real estate developers, private bankers, and entrepreneurs with Latin business ties typically pay in Miami.
Tax Residency
Spain's domestic tax law (Article 9 of the LIRPF) establishes three independent tests for tax residency. You become a Spanish tax resident if you meet any one of the following criteria during a calendar year:
For Americans from Miami, the 183-day rule is the most common trigger. The counting begins from your first day of physical presence in Spain — there is no minimum continuous stay requirement. Part days count as full days.
The year of arrival: In the year you move to Costa Brava, you may be a tax resident in both the US (for the period before you left) and Spain (from the date you established residency). The US–Spain treaty contains a tiebreaker provision that determines which country has primary taxing rights, but you will still need to file tax returns in both countries for the transition year.
Florida has no state income tax, but federal obligations remain fully in force upon Spanish residency. This state-level dimension is entirely separate from Spanish residency — you must manage both simultaneously.
Once you are a Spanish tax resident, you can apply to the Spanish Tax Agency (Agencia Tributaria) for a certificate of fiscal residency in Spain. This certificate is essential to claim treaty benefits in the US — for example, to argue that certain income should not be taxed at source in the US, or to claim the foreign tax credit on your US Form 1040.
The NIE (Número de Identificación de Extranjero) is your Spanish identification number and is required for virtually every financial transaction in Spain, including opening bank accounts, buying property, and registering with the Agencia Tributaria. You should obtain this before or very shortly after arriving in Costa Brava.
Double Tax Treaty
The US–Spain Convention for the Avoidance of Double Taxation was signed in 1990 and has been amended several times since. It is the primary legal instrument that prevents you from being taxed twice on the same income by both the United States and Spain.
Article 1 — Personal scope: The treaty applies to residents of one or both countries. As a US citizen living in Costa Brava, you are a Spanish resident, and the treaty applies to your income. However, the US "saving clause" (Article 17) means the US reserves the right to tax its citizens as if the treaty did not exist — with specific exceptions.
Article 10 — Dividends: US-source dividends paid to you as a Spanish resident are generally subject to 15% US withholding tax (5% if you hold 10%+ of voting stock). Without a treaty, the rate would be 30%. Spain then taxes you on the same dividends, but allows a credit for the US tax paid.
Article 11 — Interest: Interest on US bank accounts and bonds is generally exempt from US withholding tax under the treaty. Spain will tax the interest, and you report it on your US return but typically owe no additional US tax if you have sufficient foreign tax credits.
Article 14 — Independent personal services: If you are a self-employed consultant or freelancer originally from Miami now working remotely from Costa Brava for US clients, your income is generally taxable only in Spain (your country of residence), provided you do not have a fixed base in the US. This can represent a significant saving versus being taxed by both jurisdictions.
Article 19 — Government service: Pensions and compensation paid by the US government to former government employees (including military) are generally taxable only in the US, not Spain — an important exemption for US government retirees moving to Costa Brava.
Article 20 — Pensions and annuities: Private pensions and annuities from the US are generally taxable only in Spain as your country of residence. This means your 401(k) and IRA distributions will be subject to Spanish income tax rather than US income tax — potentially advantageous if your effective Spanish rate is lower than your US marginal rate.
As a US citizen filing Form 1040, you can claim a foreign tax credit (Form 1116) for Spanish taxes paid on income that is also taxable in the US. Properly calculating and allocating this credit across income baskets (passive, general, etc.) is one of the most technically demanding aspects of cross-border tax filing for Americans in Costa Brava.
Professionals with the income profile typical of Miami real estate, finance, and Latin-connected professionals — including South Florida real estate, foreign brokerage accounts, trust structures — often have multiple income streams that fall into different treaty categories. A single error in treaty characterisation can result in thousands of dollars of unnecessary double taxation or, conversely, an under-reporting position that triggers an IRS or Agencia Tributaria inquiry.
Modelo 720
Modelo 720 is Spain's annual informational declaration of overseas assets. All Spanish tax residents who hold foreign assets exceeding €50,000 in any of three categories must file it by 31 March each year covering the previous calendar year.
Category 1 — Bank accounts abroad: Any bank or financial account held outside Spain where the balance at 31 December, or the average balance in the last quarter, exceeds €50,000. For Americans from Miami, this includes US checking accounts, savings accounts, money market accounts, and foreign-currency accounts.
Category 2 — Securities, rights, insurance, and income: Shares, bonds, funds, pension plans, life insurance policies, annuities, and similar assets held outside Spain exceeding €50,000. This category captures South Florida real estate, foreign brokerage accounts, trust structures that many Miami residents hold.
Category 3 — Real estate and rights over real estate: Any real estate owned outside Spain with a value exceeding €50,000. If you have retained your home or investment property in Miami after moving to Costa Brava, it must be declared here.
US retirement accounts — 401(k), traditional IRA, Roth IRA, 403(b) — are a grey area. Spain has historically required their declaration under Category 2, treating them as pension/insurance contracts. The correct position depends on the specific type of account and how Spanish law characterises it. Jacob Salama advises on the correct treatment of US retirement accounts in the Modelo 720 context.
FBAR (FinCEN 114) and FATCA Form 8938 are the US equivalents — you file these with the US Treasury and IRS to report the same foreign accounts and assets from a US perspective. Americans in Costa Brava who hold Spanish bank accounts and property must file these US forms as well. The thresholds and form mechanics differ from Modelo 720.
Historically, Spain's penalties for late or incorrect Modelo 720 filing were among the most severe in the EU. Following a 2022 Court of Justice of the European Union ruling, the disproportionate penalty regime was struck down. However, Modelo 720 remains mandatory and penalties for non-filing or substantial errors continue to apply. For Americans from Miami with complex asset portfolios, professional preparation of this form is strongly recommended.
Special Tax Regimes
Spain offers two principal special tax regimes that can dramatically reduce the Spanish tax burden for qualifying American expats moving to Costa Brava: the Beckham Law (régimen especial de impatriados) and the Digital Nomad Visa (visado para teletrabajo de carácter internacional).
The Beckham Law allows qualifying individuals who become Spanish tax residents to be taxed at a flat 24% rate on Spanish-source income (up to €600,000 per year) rather than at Spain's progressive rates that reach 47%. The regime lasts for up to six calendar years (the year of arrival plus five subsequent years).
Who qualifies: The regime is available to individuals who have not been Spanish tax residents in the previous five years and who either (a) take up employment with a Spanish employer or are transferred to Spain by a foreign employer, or (b) become directors of a Spanish company in which they do not hold a 25%+ interest, or (c) conduct an economic activity classified as entrepreneurial or as a highly qualified professional under Spanish law.
For real estate developers, private bankers, and entrepreneurs with Latin business ties relocating from Miami to Costa Brava, the key question is whether your employment or business structure qualifies. If you are being transferred to Spain by your employer, or taking up a new position with a Spanish entity, the Beckham Law is often straightforwardly available. If you are self-employed or a remote worker, the qualification analysis is more complex but feasible under the entrepreneurial and highly qualified professional routes.
What the Beckham Law does NOT do: It does not exempt you from US taxation — you remain a US citizen subject to worldwide US taxation. The regime applies only to your Spanish tax position. The interaction between Beckham Law treatment and the US–Spain treaty requires careful analysis, particularly for the saving clause implications.
Introduced by Spain's Startup Law (Ley de Startups) in 2023, the Digital Nomad Visa is available to non-EU nationals — including Americans — who work remotely for companies or clients based outside Spain. It allows you to live legally in Spain and access the special Beckham Law tax regime.
Key requirements include: proof of remote work for a non-Spanish employer or clients (you may earn up to 20% of your income from Spanish sources without losing eligibility), a clean criminal record, health insurance coverage in Spain, and demonstrated income above approximately 200% of Spain's minimum wage (around €2,600 per month as a guide). The visa is initially granted for one year, renewable for two-year periods, and can lead to long-term residency.
For Americans from Miami working remotely for US-based employers or clients, the Digital Nomad Visa combined with the Beckham Law flat rate creates one of Europe's most attractive packages for tech workers, consultants, and remote professionals.
Not everyone qualifies for the Beckham Law or benefits from it equally. High earners with significant foreign-source passive income may actually prefer general Spanish residency with aggressive treaty credit planning. The decision depends on your specific income composition — employment versus passive income, Spanish-source versus foreign-source — and your long-term residency plans in Costa Brava.
