Financial Planning for Americans in Spain

Americans in Spain should review their financial planning across both the US and Spanish systems.

A proper review should usually include:

• US tax filing
• Spanish tax residence
• worldwide income
• foreign tax credits
• treaty issues
• FBAR reporting
• FATCA reporting
• Modelo 720
• Wealth Tax
• Solidarity Tax on Large Fortunes
• US brokerage access
• Spanish bank accounts
• Spanish pension arrangements
• Spanish and European investment funds
• PFIC exposure
• 401(k) planning
• IRA and Roth IRA planning
• US Social Security
• Spanish pension rights
• retirement income
• estate planning
• inheritance planning
• property
• insurance
• currency
• future residence

The central issue is that a US citizen may remain within the US tax system while becoming fully taxable in Spain.

A US brokerage account may still be relevant to Spanish income tax.

A US pension may need treaty analysis.

Foreign financial accounts and assets may create Spanish reporting requirements.

Larger balance sheets may also need Spanish Wealth Tax and, where relevant, the Solidarity Tax on Large Fortunes reviewed.

The planning point is simple.

A financial decision should not be made under US rules alone when the person is resident in Spain.

The main challenge for Americans in Spain is coordination.

Spain can be an attractive place to work or retire, but it has several planning features that make it materially different from simply living abroad while retaining US accounts.

Foreign asset reporting and wealth taxation are especially important.

1. US tax generally continues when you move to Spain

A US citizen does not normally leave the US tax system by becoming resident in Spain.

US citizens and resident aliens abroad are generally subject to US tax on worldwide income.

Your US filing may therefore still need to consider:

• Spanish salary
• self-employment income
• dividends
• interest
• investment gains
• pension income
• rental income
• Spanish financial accounts
• foreign investment funds
• Spanish pensions
• property
• business interests
• trusts
• other overseas assets and income

This creates an overlap once Spain also treats the person as tax resident.

Foreign tax credits and the US-Spain treaty may help manage double taxation, but they do not remove the need to review both systems.

2. Spanish tax residence can bring worldwide income into scope

Spanish tax residents are generally taxed on worldwide income.

For an American living in Spain, that can mean Spanish tax needs to be considered on:

• US employment income
• US dividends
• interest
• brokerage gains
• rental income
• retirement-account withdrawals
• pensions
• other foreign income

This means keeping the account in the US does not necessarily preserve its purely American tax treatment.

The residence position should therefore be established before restructuring investments or taking major pension withdrawals.

3. The US-Spain tax treaty should be part of the analysis

The United States and Spain have an income tax treaty dating from 1990, subsequently amended by a protocol signed in 2013.

The IRS maintains the treaty, technical explanation, protocol and updated technical material. (irs.gov)

The treaty addresses areas including:

• residence
• employment income
• business income
• dividends
• interest
• capital gains
• pensions
• Social Security
• government service
• relief from double taxation

For Americans, the treaty should be read alongside US domestic law and the treaty's provisions preserving certain US taxing rights over citizens.

Do not assume a treaty provision automatically overrides US taxation.

4. US retirement accounts need Spain-aware planning

Many Americans moving to Spain retain substantial US retirement assets.

These may include:

• 401(k)
• traditional IRA
• Roth IRA
• 403(b)
• 457(b)
• TSP
• inherited IRA
• employer pensions
• annuities

Review:

• whether the custodian supports a Spanish address
• whether investment restrictions apply
• whether ongoing advice remains available
• US taxation of distributions
• Spanish taxation of distributions
• treaty treatment
• Required Minimum Distributions
• Roth IRA treatment
• beneficiaries
• investment strategy
• USD versus EUR exposure
• future retirement location

The key point is that the US wrapper does not automatically determine the Spanish tax result.

5. Roth IRAs need particular care

Roth IRAs can be especially problematic conceptually because the US position is easy to understand.

Qualified withdrawals can be tax-free for US federal purposes.

That does not mean Spain must automatically recognise the same tax treatment.

Before making:

• Roth conversions
• large withdrawals
• new contributions
• beneficiary decisions

the Spanish position should be confirmed by a suitably qualified US-Spain tax adviser.

The correct strategy may depend on where the person expects to be resident when withdrawals are ultimately taken.

6. Spanish pensions should be coordinated with US retirement assets

An American working in Spain may build Spanish state pension rights while retaining significant US retirement assets.

The eventual retirement plan may include:

• US Social Security
• 401(k)
• traditional IRA
• Roth IRA
• Spanish state pension
• employer retirement benefits
• investments
• cash
• property

These sources may differ in:

• access age
• tax treatment
• inflation protection
• beneficiary rules
• currency
• reporting
• portability

The correct objective is not to optimise each account separately.

It is to build one retirement-income strategy across all available assets.

7. The US-Spain Social Security agreement can help mobile workers

The US-Spain Social Security Agreement was signed on 30 September 1986 and entered into force on 1 April 1988.

The agreement coordinates the two Social Security systems.

It can help:

• avoid dual coverage in qualifying circumstances
• establish which country's system applies
• allow US and Spanish contribution periods to be combined for certain benefit-entitlement purposes

For US benefits, Spanish credits can potentially help someone qualify where they do not have enough US credits, provided the relevant minimum US coverage conditions are met.

For Spanish benefits, US periods may also be taken into account where needed.

Each country still calculates and pays its own benefit.

8. Spanish and European funds can create PFIC exposure

An American in Spain may be offered:

• Spanish mutual funds
• UCITS funds
• European ETFs
• Luxembourg funds
• Irish funds
• bank-managed portfolios
• insurance-linked investment funds

These may be mainstream products in Spain.

For a US taxpayer, however, many non-US pooled investment companies can potentially fall within the Passive Foreign Investment Company regime.

PFIC exposure can create:

• Form 8621 reporting
• complex annual calculations
• potentially unfavourable US taxation
• additional accounting costs
• administrative difficulties

The US classification should therefore be checked before buying local or European funds.

9. Spanish tax-efficient investments are not automatically US-efficient

This is a recurring cross-border problem.

A Spanish bank or adviser may recommend a structure because it is efficient under Spanish rules.

But the United States may classify the underlying investment differently.

That means the planning process should ask two questions:

How is the investment treated in Spain?

and:

How is it treated in the United States?

A portfolio is not truly tax-efficient if it solves one jurisdiction while creating a larger problem in the other.

10. Modelo 720 can be relevant to foreign assets

Spain operates an information-reporting regime for certain assets and rights held abroad through Modelo 720.

The Spanish Tax Agency describes Modelo 720 as the information return covering three foreign-asset reporting obligations.

For an American living in Spain, potentially relevant assets can include categories such as:

• foreign financial accounts
• securities and investments
• certain rights and insurance arrangements
• foreign property

The precise thresholds and filing requirements should be confirmed with a Spanish tax adviser.

The key planning point is that a US brokerage account or bank account can create a Spanish reporting obligation even though it remains entirely in America.

11. Spain's Wealth Tax can change portfolio planning

Spain also has a separate Impuesto sobre el Patrimonio, or Wealth Tax.

The Spanish Tax Agency continues to administer Wealth Tax and publishes annual filing guidance.

The tax position can depend on:

• residence
• total wealth
• asset type
• exemptions
• debt
• regional rules
• ownership structure

For a high-net-worth American, substantial holdings in:

• US brokerage accounts
• shares
• property
• business interests
• cash
• other assets

may need to be considered.

The analysis should be done alongside investment planning because asset ownership and portfolio structure can affect the Spanish wealth-tax position.

12. Regional rules make Spanish Wealth Tax more complicated

Spain's autonomous communities can materially affect the final Wealth Tax outcome.

That means living in Madrid, Catalonia, Andalusia, Valencia or another region can produce a different position.

This is particularly relevant for internationally mobile families deciding:

• where in Spain to settle
• when to become resident
• whether to retain significant foreign assets
• how property and investment ownership should be structured

Regional tax advice should therefore be taken before assuming one national calculation applies everywhere.

13. Large portfolios may also need the Solidarity Tax on Large Fortunes reviewed

Spain also operates the Impuesto Temporal de Solidaridad de las Grandes Fortunas, commonly referred to as the Solidarity Tax on Large Fortunes.

The Spanish Tax Agency states that the tax applies to individual net wealth exceeding €3 million, subject to the detailed statutory rules and interaction with Wealth Tax.

The filing mechanics were updated again in June 2026 for the return relating to the 2025 tax year.

For HNW Americans in Spain, this can make seemingly ordinary US assets relevant to an additional Spanish tax layer.

This should be modelled with specialist Spanish tax advice rather than treated as an investment issue alone.

14. US brokerage accounts still need ongoing review

Keeping investments in America can help avoid some local-fund and PFIC problems.

But the account still needs to work operationally.

Review:

• whether the provider accepts Spanish residents
• whether investment purchases become restricted
• whether advice can continue
• whether US mutual funds remain available
• Spanish taxation of income and gains
• Modelo 720 reporting
• Wealth Tax treatment
• currency exposure

The best investment structure needs to be both technically appropriate and practically usable.

15. FBAR and FATCA operate in the other direction

Spain may require information about foreign US assets.

The United States may require information about Spanish financial accounts.

Americans in Spain may hold:

• Spanish current accounts
• savings accounts
• investment accounts
• pension accounts
• business accounts
• insurance arrangements
• joint accounts
• accounts over which they have signing authority

These may create US FBAR or FATCA reporting obligations.

This creates a two-way reporting framework.

The financial plan should capture:

• what Spain needs to know about US assets
• what the US needs to know about Spanish assets
• whether underlying investments create separate PFIC reporting

16. Property can materially change the balance sheet

Many Americans moving to Spain eventually purchase property.

That can alter:

• EUR exposure
• liquidity
• wealth-tax calculations
• estate planning
• local taxation
• concentration risk
• retirement cash flow

A €1 million property is not simply a housing decision if most other assets remain in USD retirement accounts.

The balance sheet should be considered as a whole.

17. Estate planning is highly regional in Spain

Spain has an inheritance and gift tax regime, and autonomous-community rules can materially affect the final position.

The Spanish Tax Agency confirms that inheritance and gift taxation can involve either state or regional rules depending on the relevant connecting factors, and that regional legislation can be available even in certain cross-border cases.

For an American family, estate planning may therefore need to consider:

• US wills
• Spanish wills
• spouse rights
• children's rights
• beneficiary nominations
• retirement accounts
• life insurance
• Spanish property
• US property
• trusts
• US estate tax
• Spanish inheritance tax
• regional exemptions and allowances
• estate liquidity

Generic “Spanish inheritance tax” figures should not be relied upon without establishing which regional rules apply.

18. Cross-border inheritances require additional care

Spain's tax authority specifically addresses situations involving:

• non-resident heirs
• Spanish assets
• foreign assets inherited by Spanish residents
• life insurance
• gifts
• applicable regional legislation.

This matters for Americans because family members may live in several countries.

The person who dies, the beneficiary, the asset location and the Spanish region can all affect the result.

Cross-border estate planning should therefore be coordinated with qualified US and Spanish legal and tax advisers.

19. Currency planning matters as spending shifts to euros

An American in Spain may hold most financial wealth in USD while living expenses are predominantly in EUR.

Typical holdings may include:

• 401(k) in USD
• IRA in USD
• Roth IRA in USD
• US brokerage accounts in USD
• Social Security in USD
• Spanish pension rights in EUR
• Spanish property in EUR
• living expenses in EUR

Currency planning should consider:

• emergency cash
• near-term spending
• property costs
• tax bills
• retirement withdrawals
• healthcare
• investment horizon
• future residence

The aim is not to predict whether the dollar or euro will strengthen.

It is to make sure future liabilities are not entirely dependent on one exchange rate at one point in time.

20. Future residence should influence today's financial plan

Spain may be your permanent home.

It may also be one stage of an international career or retirement.

You may eventually:

• remain in Spain
• return to the United States
• move to the UK
• relocate to Portugal
• move elsewhere in Europe
• retain Spanish pension rights
• keep US retirement accounts
• retain Spanish property
• leave assets to beneficiaries in several countries

That can change:

• retirement-account taxation
• investment suitability
• wealth taxation
• estate planning
• provider access
• reporting
• currency exposure

The financial plan should therefore preserve flexibility wherever possible.

Financial planning for Americans in Spain, US tax, Spanish tax, tax residence, treaty treatment, foreign tax credits, US retirement accounts, Spanish pensions, Social Security, Spanish social security, FBAR, FATCA, PFICs, Modelo 720, Wealth Tax, Solidarity Tax on Large Fortunes, Spanish and European funds, brokerage access, estate planning, inheritance tax, property, regional tax rules, currency and future residence depend on personal circumstances and may change.

US tax advice should be taken from a suitably qualified US tax adviser or CPA.

Spanish tax and legal advice should be taken from suitably qualified Spanish advisers where relevant.

Financial planning should be coordinated with tax, legal, pension, investment, retirement and estate-planning advice where appropriate.

Do not invest, withdraw, transfer, restructure, contribute, roll over, surrender, relocate or materially alter ownership of assets without reviewing US and Spanish tax, investment, pension, estate, reporting, wealth, property, currency and retirement-planning implications.

Investing involves risk. Investment, pension and retirement-account values can fall as well as rise, and you may get back less than you invest.

Currency movements can affect investments, pensions, retirement accounts, property, tax liabilities, income and future spending.

Tax rules, regional rules, treaty interpretation and the treatment of particular retirement and investment structures can change. The appropriate position should be confirmed using the rules applying when advice is taken.
