What to Review Financially Before Moving from the US to Spain

October 23, 2026

Someone who has built up significant investment gains while living in the US can move to Spain, sell a few months later, and find that Spain taxes the whole gain. Almost all of that growth happened before they lived in Spain. The problem is simply that the sale took place after they became Spanish tax resident, rather than before.

That pattern sits behind many of the issues I see when advising Americans on a move to Spain. Decisions that would have been straightforward a few months earlier become harder, or more expensive, once Spanish tax residence begins.

The short answer: before you move, review when you will become Spanish tax resident, any large sales or withdrawals you are planning around that date, how your retirement accounts will be taxed, whether your US providers can keep working with you, and whether your will still does what you want.

Introduction

If you have been keeping your UK pension to leave to your children, April 2027 is a reason to check that plan. Living in Spain does not, by itself, put a UK-established pension outside UK inheritance tax.

From 6 April 2027, most unused pension funds and pension death benefits will count towards your estate for UK inheritance tax. In many cases, inherited pension payments can also face income tax. One tax does not replace the other, but not every family will pay both.

The question worth asking is simple: after the taxes that apply, how much could your family keep?

What You Will Learn

Why your arrival date dictates your whole year’s tax bill.
How Spain taxes US retirement accounts.
How to avoid the US/EU investment trap.
Which non-negotiable deadlines apply to your visa and assets.

What changes when you become Spanish tax resident?

You keep your US filing obligations, and Spain starts taxing your worldwide income too, unless you qualify for the Beckham Law (covered below). Spain generally treats you as resident if you spend more than 183 days there in a calendar year, if your main economic interests are there, or, by presumption, if your spouse and dependent children live there.

Three points tend to surprise people:

No split year. Spain treats you as resident or non-resident for the whole calendar year, so the timing of your move, and of any big transactions that year, matters.
Currency counts. For a Spanish resident, converting dollars into euros can itself create a taxable gain or loss.
Where you settle matters. Spanish wealth tax and inheritance tax vary by region, so choosing where to live is partly a financial decision. A separate national tax on very large fortunes applies in every region.

Could Spain tax investment gains you made before moving there?

It can be. HMRC says relevant benefits in UK-established pension schemes are within the new rules even if the member is no longer a long-term UK resident. Whether tax is actually due depends on the benefits, the available allowances and who inherits.

Imagine you have lived in Spain for 12 years, have a £400,000 pension in a UK-established scheme and want to leave it to your children. Those 12 years abroad do not, by themselves, exempt that pension. Your wider estate still needs checking before anyone can calculate a bill.

I've lived outside the UK for 10 years. Do the rules still affect me?

Often, yes.

Spain generally measures a gain from what you originally paid, not from the value on the day you arrived. Growth built up while you lived in the US can therefore be taxed in Spain if you sell after becoming resident.

Example. Imagine a couple who bought shares in a US brokerage account years ago, and the shares have grown by $200,000. They move to Spain in March and plan to sell in the autumn to buy a home. Because they will spend more than 183 days in Spain that year, Spain treats them as resident for the whole year. It will generally tax the full gain, measured from what they originally paid and reported in euros, even though almost all of it built up while they lived in the US. The US will also tax the gain, and while credits usually reduce the overlap, they do not always remove it entirely. Had they reviewed this before the move, they could have compared selling in the year before becoming resident with selling afterwards. (Figures are illustrative.)

Selling before the move is not automatically better. It depends on the asset, your US federal and state tax position and the Spanish rates that would apply. The same question applies to a US home, a rental property or shares in a business.

They move to Spain in March and plan to sell in the autumn to buy a home. Because they will spend more than 183 days in Spain that year, Spain treats them as resident for the whole year.

It will generally tax the full gain, measured from what they originally paid and reported in euros, even though almost all of it built up while they lived in the US. The US will also tax the gain, and while credits usually reduce the overlap, they do not always remove it entirely.

Had they reviewed this before the move, they could have compared selling in the year before becoming resident with selling afterwards.

(Figures are illustrative.)

It can also catch sales made before you arrive.

Because Spain looks at the whole calendar year, a sale in the early months can fall into your first Spanish tax year.

Take someone who sells their US home in February and moves to Spain in May. If they spend more than 183 days in Spain that year, Spain’s starting position is that it can tax the gain, even though they still lived in the US when they sold.

Had they moved in September instead, spending fewer than 183 days in Spain that year and with no other strong ties to Spain, that year would generally stay outside Spanish tax.

Unlike the UK, which has split-year treatment in certain cases, Spain has no split-year rule. Its stated position is that tax treaties do not split the year either, although this can be contested. The US home-sale exclusion does not reduce the Spanish tax, but Spain has its own relief: reinvesting the full proceeds in a new main home within two years.

A recent Spanish tax authority ruling accepted this for a US home (DGT V1860-25), subject to conditions. (Illustrative.)

What happens to my 401(k) or IRA if I move to Spain?

The accounts can usually stay where they are. What changes is how withdrawals are taxed, and the answer is not the same for everyone:

Traditional 401(k)s and IRAs. Withdrawals generally remain taxable in the US and become taxable in Spain too. Foreign tax credits reduce the overlap, but not always completely. US state income tax is not covered by the US-Spain tax treaty, and some states can keep treating you as resident after you leave.
US government pensions. Pensions from federal, state or local government service are generally taxable only in the US under the treaty, unless you are also a Spanish national.
Roth IRAs. Qualified withdrawals are tax-free under US law, but Spain does not follow that. In a binding ruling, Spain’s tax authority treated a Roth IRA as not being a pension plan: a lump-sum withdrawal was taxed as savings income on the growth (the amount received minus contributions), and the account had to be reported on Modelo 720 (DGT V1291-22). Rulings apply to their own facts, so check how it fits yours.
Beckham Law. If you qualify for Spain’s special regime for people moving there to work, generally only Spanish-source income is taxed, for the year you arrive and the next five. Employment income counts as Spanish-source. The regime is aimed at people moving for work or to run a business, so most retirees on a Non-Lucrative Visa will not qualify.

Many people assume a Roth stays tax-free wherever they live. Spain’s tax authority does not see it that way, which is why it is worth planning before you move.

At a Glance: How Spain Taxes US Retirement and Investment Accounts (2026)

US Account Type	US Tax Treatment	Spanish Tax Treatment (Standard Resident)	Modelo 720 Reporting (>€50,000)	Pre-Move Planning Window
Traditional 401(k) & Traditional IRA	Taxed as ordinary income upon withdrawal (10% penalty before age 59½).	Taxed as general income (renta general) at progressive regional rates up to 47%–50%.	Generally exempt until withdrawal rights are exercised, depending on plan structure.	Evaluate partial drawdowns or Roth conversions in a tax year prior to becoming Spanish resident.
Roth IRA & Roth 401(k)	Qualified withdrawals of both contributions and growth are 100% tax-free.	Taxable in Spain. Treated as a non-pension financial asset (DGT V1291-22). Growth is taxed as savings income at 19% to 30%.	Required if combined values in the securities/annuities category exceed €50,000.	Take lump-sum distributions or restructure before 1 January of your first Spanish tax year.
US Brokerage Account (Stocks & ETFs)	Long-term capital gains taxed at 0%, 15%, or 20% (plus 3.8% NIIT where applicable).	Worldwide gains taxed on the savings scale (19% up to €6k; 21% up to €50k; 23% up to €200k; 27% up to €300k; 30% over €300k), plus currency gain/loss calculations in euros.	Required if total foreign securities exceed €50,000 at year-end or Q4 average.	Realise built-up gains to rebase your cost basis in the calendar year before Spanish residency begins.
US Government Service Pensions	Taxed at standard US federal (and applicable state) income tax rates.	Exempt from direct tax in Spain under Article 21 of the US–Spain Tax Treaty (unless you hold Spanish nationality), though counted when calculating your marginal rate on other income.	Exempt from Modelo 720 reporting.	Confirm whether your pension qualifies as public civil service vs. a private/public hybrid plan before relocating.

Tia’s Adviser Note: Why the Roth IRA Is the Biggest Blind Spot for Americans

“At PCC Wealth, the single hardest conversation I have is with Americans who completed a large Roth conversion five months before moving to Madrid or the Costa del Sol, assuming they had locked in tax-free retirement income for life. Under US rules, they did the textbook thing. Under Spanish rules, they just created a problem.

Because Spain’s Directorate-General for Taxation (DGT V1291-22) does not recognise a Roth IRA as a qualifying pension plan, Spain looks through the wrapper. Worse still, if you convert a Traditional IRA to a Roth in February and move to Spain in June of the same calendar year, you risk triggering US income tax on the conversion and bringing that same tax year inside the Spanish tax net.

Through our Americans Moving to Spain partnership, we model the numbers across both tax systems twelve months ahead of your visa application so you never pay tax twice on the same retirement dollar.”

Can I keep my US investments and my US financial adviser?

Sometimes, but do not assume it. Some US brokerages restrict trading or new purchases once you have a foreign address, and whether a US adviser can keep advising you depends on their firm’s regulatory permissions for clients abroad.

Ask each provider in writing what happens once you live in Spain.

Switching to local investments is not straightforward either. Most European funds and ETFs are likely to be PFICs for US tax purposes, which can be taxed harshly and generally need a separate Form 8621 each.

Meanwhile, EU PRIIPs rules mean most US-listed ETFs cannot be bought on EU platforms as a retail investor.

This does not force you to sell US ETFs you already hold, but deciding how your portfolio will be held before you move avoids being stuck with whatever is left.

Tia’s Adviser Note: Solving the Cross-Border "Catch-22" Before Your Account Is Frozen

“Many US expats only discover the cross-border investment trap after they update their residential address to Spain and receive a 60-day account-closure notice from their US brokerage.

You cannot simply walk into a Spanish bank and buy local mutual funds without triggering punitive US PFIC (Passive Foreign Investment Company) taxes and costly Form 8621 accounting fees. At the same time, EU PRIIPs rules block European retail platforms from letting you buy standard US-domiciled ETFs because they lack a European Key Information Document (KID).

At Private Client Consultancy Wealth, we resolve this before you board the plane. By transitioning portfolios to specialist cross-border custodial platforms that accept both US citizens and Spanish residents, or by constructing compliant portfolios using individual equities and institutional reporting structures, you stay fully compliant with both the IRS and the Spanish Agencia Tributaria without sacrificing investment performance.”

Do I need to review my US will before moving to Spain?

Usually, yes.

Under the EU Succession Regulation, your estate is governed by the law of the country where you are habitually resident when you die. Once Spain is home, that can mean Spanish forced heirship rules, which vary by region, unless your will clearly chooses the law of your nationality.

For Americans that choice is less simple than it sounds, because inheritance law in the US is set state by state.

Tax is a separate question. Spanish inheritance tax is paid by the person inheriting and varies by region, and Spain is not on the IRS list of estate and gift tax treaty countries. This needs lawyers qualified in both systems.

Why plan your finances alongside the visa?

The two are linked, and the deadlines are tight.

The Non-Lucrative Visa needs proof of financial means and does not allow you to work.

The Beckham Law must be applied for within six months of the start date on your Spanish Social Security registration, or on your certificate of coverage if you stay in another country’s system, (Real Decreto 439/2007, art. 116).

The first Modelo 720, where it applies, is due between 1 January and 31 March of the year after your first year of residence (Orden HAP/72/2013, art. 7). Running the financial review alongside the visa process gives you time to act on what it finds.

Chronological Checklist: Coordinating Your US Financial Review with Your Spanish Visa

Relocation Stage	Key Financial & Tax Actions	Visa & Administrative Milestones	Governing Spanish / US Rule
6–12 Months Before Moving (Prior Calendar Year)	Audit unrealized capital gains on US shares and real estate; execute any planned sales, capital-gain harvesting, or Roth IRA withdrawals before 31 December. Ask US brokerages in writing for their policy on Spanish residents.	Select your visa route (e.g. Non-Lucrative Visa vs. Digital Nomad Visa) and compare regional tax rules (such as Andalucía’s 0% standard Wealth Tax up to the €3m Solidarity Tax threshold vs. Cataluña or Valencia).	Spanish full calendar-year tax residency rule (no split-year treatment); 2026 Spanish savings tax scale (19%–30%).
1–3 Months Before Moving	Restructure brokerage holdings into PFIC-compliant and PRIIPs-compliant wrappers. Draft or update cross-border wills specifying US state nationality law.	Gather apostilled financial statements proving passive income or bank balances for your US consulate visa appointment.	EU Succession Regulation (Brussels IV); IRS Form 8621 (PFIC rules).
First 6 Months in Spain	Register for the Beckham Law (if moving for qualifying employment or directorship) to keep non-Spanish worldwide investment income outside the Spanish tax net.	Obtain your TIE card, register on the local padrón, and complete Spanish Social Security registration (or US Certificate of Coverage).	Real Decreto 439/2007, art. 116 (strict 6-month deadline from Social Security registration).
1 January – 31 March of Year 2	File your first Modelo 720 informative declaration if your foreign bank accounts, investment securities, or overseas property exceed €50,000 in any single category. Prepare for your first Spanish Declaración de la Renta (filed May–June).	Prepare documentation for Year 1 visa renewal where applicable.	Orden HAP/72/2013, art. 7 (Modelo 720 window); main-home reinvestment relief window of 2 years (DGT V1860-25).

Which financial decisions do Americans most often leave too late?

In my work with Americans moving to Spain, these come up again and again:

Selling property or investments. A US home or portfolio sale is often timed around practical things, like the closing date or when the furniture ships, without checking which tax year it falls into. A few months either way can change which country taxes the gain.
The Roth IRA. This is the question I hear most. Whether to keep a Roth, draw it down, or convert a traditional IRA into one is far easier to decide while only US rules apply. Any plan to draw on it early also needs checking against the US rules, because withdrawing earnings before age 59½ can mean US tax plus a 10% additional tax (IRS Publication 590-B).
US brokerage accounts. Some US firms restrict trading, block new fund purchases or close accounts once a client lives abroad. If an account is closed and the holdings have to be sold, that sale can be taxable in the US and, once you are resident, in Spain too. It is worth checking each provider’s policy before you move.
The Beckham Law. The six-month window runs from Social Security registration, and some people only hear about the regime once it has closed.

The reason is usually the same. The visa process has fixed deadlines and the financial review does not, so it gets pushed back. By the time people ask “Should I have done my Roth conversion before I arrived?” or “If I sell my US shares this year, will Spain tax the whole gain?”, the simpler options have often passed.

When should I start financial planning for a move to Spain?

Ideally as soon as the move is a serious possibility, and well before your first year of Spanish residence begins.

Not every American needs to restructure before moving, and for some people very little changes. But the earlier you review your arrangements, the more room you have to deal with issues before your circumstances change.

This article focuses on the financial decisions that are easiest to get right before you move. For the wider relocation picture, including visas, healthcare, Social Security and the practical steps of the move, see our guide:

Frequently Asked Questions

How is US Social Security taxed when living in Spain?

For Spanish tax residents, US Social Security retirement benefits are taxed in both countries under the US–Spain Income Tax Treaty.

In Spain, Social Security counts as general pension income (rendimientos del trabajo) and is taxed at progressive income tax rates.

You can claim a Foreign Tax Credit to offset double taxation, though the higher of the two countries’ tax rates applies.

What is the €50,000 rule for Modelo 720 in Spain?

Spanish tax residents must file Modelo 720 between 1 January and 31 March if their non-Spanish assets exceed €50,000 in any of three separate categories: foreign bank accounts, foreign investment securities/annuities/Roth IRAs, or foreign real estate.

The €50,000 threshold is calculated per category rather than across your combined global assets.

Can I use the Spanish main-home reinvestment relief when selling a US house?

Yes, provided specific conditions are met.

While the US Section 121 home-sale exclusion ($250,000 single / $500,000 married) does not apply in Spain, a binding Spanish tax authority ruling (DGT V1860-25) confirmed that expats whose US primary residence sale falls into a Spanish tax year can claim Spanish main-home capital gains relief if they reinvest the proceeds into a new primary home within two years.

How does living in Andalucía affect Spanish wealth tax for US expats?

Andalucía applies a 100% regional bonification on standard Spanish Wealth Tax, effectively reducing regional wealth tax to 0% for residents on the Costa del Sol and the rest of the region.

However, Spain’s national Solidarity Tax on Large Fortunes (Impuesto Temporal de Solidaridad de las Grandes Fortunas) still applies across all regions at rates of 1.7% to 3.5% once individual net worldwide wealth exceeds €3 million (or roughly €4 million after standard and main-home allowances).

What happens if I keep a US LLC or S-Corp after becoming a Spanish tax resident?

Spain does not automatically mirror the US “pass-through” tax treatment of an S-Corp or single-member LLC.

Depending on its operating documents and whether it is considered managed and controlled from Spain, the Spanish tax authority may classify a US LLC either as a transparent entity or as a foreign corporation subject to both entity-level tax and dividend tax, requiring pre-move restructuring.

Bringing Your US-to-Spain Financial Plan Together

Relocating from the United States to Spain requires managing two tax systems that measure income, investment growth, and calendar years differently.

Because Spain does not split the tax year, the date your visa begins, and the month you cross the 183-day threshold, determines whether decades of built-up US capital gains, property proceeds, and Roth IRA distributions are taxed solely in America or taxed again under Spanish savings rates of up to 30%.

Reviewing your portfolio, retirement wrappers, and estate plan in the calendar year before you establish Spanish tax residence gives you the flexibility to act while simpler, lower-tax options are still available.
