Moving to Spain: Tax Checklist

Relocating to Spain is an exciting personal decision, but it can also be an important tax event.

For U.S. citizens, green card holders, entrepreneurs, investors and families with assets in more than one country, the move may affect income taxation, foreign asset reporting, investments, retirement accounts, business structures, wealth tax exposure and ongoing compliance in both Spain and the United States.

The best time to address these issues is before Spanish tax residency begins.

Once residency has started, many planning opportunities may become more limited. A pre-relocation review allows you to identify the main risks, organize the right information and make informed decisions before your personal and financial life becomes connected to the Spanish tax system.

Below is a practical checklist of questions to consider before moving to Spain.

1. When could Spanish tax residency begin?

The first question is not simply when you arrive in Spain. It is when Spain may consider you tax resident.

Under Spanish domestic rules, an individual may be treated as tax resident in Spain if they spend more than 183 days in Spain during the calendar year, if the main center or base of their activities or economic interests is located in Spain, or, subject to rebuttal, if their spouse and dependent minor children habitually reside in Spain. Spain also generally treats tax residency as applying for the entire calendar year; a change of residence does not split the Spanish tax year into resident and non-resident periods.

This makes timing important.

Before relocating, consider:

What date do you expect to enter Spain?
How many days will you spend in Spain during the first calendar year?
Will your spouse or minor children move before or after you?
Where will your main professional, business or investment activity be located?
Will you remain tax resident in another country during the transition year?

For U.S. individuals, this analysis is especially important because the United States may continue to impose tax and reporting obligations even after the move. U.S. citizens and resident aliens living abroad generally remain subject to U.S. tax on worldwide income, although exclusions, foreign tax credits and treaty considerations may apply.

2. What income will you have after the move?

Spanish tax residency can change how income is reported and taxed.

Spanish tax residents are generally subject to Personal Income Tax on worldwide income, meaning income must be declared in Spain regardless of where it is earned or where the payer is located, subject to any applicable double tax treaty.

Before moving, identify each category of income you expect to receive:

Salary or remote work compensation
Self-employment or consulting income
Business distributions
Dividends and interest
Capital gains
Rental income
Stock options or equity compensation
Pension or retirement distributions
Social Security or other government benefits
Trust, estate or partnership income

Each type of income may be treated differently under Spanish tax law, U.S. tax law and the U.S.–Spain income tax treaty. The correct answer often depends on the source of the income, timing of payment, legal form of the asset, and whether the income is earned before or after Spanish tax residency begins.

A pre-relocation income review can help determine whether certain income should be accelerated, deferred, restructured or simply documented more clearly before the move.

3. What foreign accounts and assets will need to be reported?

Many internationally mobile clients focus on income tax, but reporting obligations can be equally important.

Spanish tax residents may have informational reporting obligations for assets and rights located outside Spain. Form 720 is Spain’s informational return for certain foreign assets and rights. The Spanish Tax Agency describes it as an informative tax return on goods and rights located abroad, with a recent filing period running from January 1 to March 31 for the relevant campaign.

Form 720 is not the same as paying tax. It is a disclosure form. However, it can apply to assets that many new residents continue to hold abroad, including foreign bank accounts, securities, insurance products and real estate, depending on the facts and thresholds. The Spanish Tax Agency’s guidance refers to a €50,000 threshold in determining whether certain assets must be declared.

U.S. reporting may also continue. For example, a U.S. person with foreign financial accounts may need to file an FBAR if the aggregate value of foreign financial accounts exceeds $10,000 at any time during the calendar year.

Before moving, prepare an inventory of:

Bank accounts
Brokerage accounts
Retirement accounts
Life insurance or annuity contracts
Foreign companies or partnerships
Real estate
Digital assets and custodial arrangements
Accounts where you have signature authority but no ownership

This inventory should include the owner, location, account number, year-end value, maximum value, currency and whether the account is held individually, jointly, through a company or through a trust.

4. Should investment accounts be reviewed before residency?

Investment portfolios often require careful pre-relocation planning.

An investment structure that works well for a U.S.-based taxpayer may create complications after moving to Spain. This is particularly true for brokerage accounts, investment funds, exchange-traded funds, private funds, insurance wrappers, concentrated positions and assets with significant built-in gains.

Before becoming Spanish tax resident, consider:

Do you hold assets with large unrealized gains?
Would selling before residency produce a different tax result than selling after residency?
Are any funds, entities or investment products treated differently in Spain than in the United States?
Will your U.S. brokerage allow you to maintain the account after moving abroad?
Will dividend, interest or capital gain reporting be available in a format useful for Spanish compliance?
Are foreign exchange gains or losses relevant?
Do you have complete cost basis records?

This review is not only about tax rates. It is also about documentation. Spanish tax compliance often requires information that U.S. financial institutions do not automatically present in the same way. Gathering statements, cost basis history and transaction records before the move can save time and reduce uncertainty later.

5. Are retirement accounts and pensions properly mapped?

Retirement assets are often among the most important cross-border planning items.

U.S. retirement accounts, employer plans, IRAs, Roth IRAs, pensions and Social Security benefits may raise questions under Spanish tax law and the U.S.–Spain tax treaty. The tax treatment may depend on the type of plan, whether contributions were pre-tax or after-tax, the timing of distributions, and whether the account is considered pension, investment, insurance or another type of asset for Spanish purposes.

Before relocating, identify:

Traditional IRAs
Roth IRAs
401(k), 403(b) or similar employer plans
Pension plans
Deferred compensation plans
Social Security benefits
State, local or government retirement benefits
Non-U.S. retirement or pension arrangements

A key pre-relocation question is whether distributions are expected soon after the move. If so, the timing and classification of those distributions should be reviewed before residency begins.

6. Do you own a business or professional activity?

Business owners, founders, consultants and remote professionals often face additional tax questions.

A move to Spain can affect not only personal income tax, but also corporate tax, self-employment status, payroll, permanent establishment risk, VAT, social security and the classification of foreign entities.

Before moving, consider:

Do you own shares in a U.S. corporation, LLC, partnership or S corporation?
Will you manage the business from Spain?
Will directors, employees or contractors be located in Spain?
Where will contracts be negotiated and signed?
Where will clients be located?
Will you invoice personally or through an entity?
Will the company create a taxable presence in Spain?
Are there retained earnings or planned distributions?
Are there stock options, restricted stock units or founder shares?

For many entrepreneurs, the most important planning step is to understand the structure before the move. Entity classification can differ between countries, and a structure that is efficient in one jurisdiction may be inefficient or administratively burdensome in another.

7. Could the special inbound worker regime apply?

Spain’s special tax regime for inbound workers, often referred to as the Beckham Law regime, may be relevant for some individuals moving to Spain.

The Spanish Tax Agency explains that the special regime under Article 93 of the Personal Income Tax Law was modified from January 1, 2023 to include additional categories such as remote workers, entrepreneurs and certain qualified professionals, and to extend possible application to certain family members. Under the regime, qualifying individuals who become Spanish tax resident because of their move may elect to be taxed under Non-Resident Income Tax rules, with certain special features, while remaining Personal Income Tax taxpayers.

This regime can be highly relevant, but it is not automatic and does not fit every case.

Before moving, review:

Whether you meet the eligibility requirements
Whether your reason for moving fits within the qualifying categories
Whether your spouse or children may also qualify
How the regime would affect Spanish taxation of income and assets
How it interacts with U.S. tax obligations
Whether the application deadline can be met

The regime may also affect reporting obligations. Spanish Tax Agency guidance states that an individual resident in Spain who is registered under the Article 93 special regime is not required to submit Form 720, although other family members may still have obligations depending on their own tax status.

Because the election can significantly change the Spanish tax outcome, it should be reviewed before relocation rather than after arrival.

8. Will Spanish wealth taxes be relevant?

Spain has wealth-based taxes that may be relevant for individuals with significant assets.

Spanish Wealth Tax and the Temporary Solidarity Tax on Large Fortunes are separate from income tax. The Spanish Tax Agency identifies Wealth Tax as a distinct tax and provides a specific Form 714 procedure for filing. The Spanish Tax Agency also maintains a separate section for the Temporary Solidarity Tax on Large Fortunes, with Form 718 procedures and information on taxable assets, filing obligations and deadlines.

Whether these taxes apply depends on factors such as residency status, asset values, exemptions, liabilities, location of assets and the autonomous community involved.

Before moving, prepare a balance sheet showing:

Real estate
Bank and brokerage accounts
Business interests
Retirement accounts
Insurance products
Loans and liabilities
Art, collectibles or other valuable assets
Ownership percentages
Spouse or family ownership
Asset location and valuation date

High-net-worth individuals should review wealth tax exposure before becoming Spanish tax resident, especially if they own significant investment portfolios, real estate or private business interests.

9. Are real estate decisions timed correctly?

Real estate can create tax issues before, during and after relocation.

If you own a U.S. home, Spanish property or other foreign real estate, consider how each property will be used after the move. A home may become a rental property, a former principal residence, a vacation property or an investment asset. Each use can affect income tax, capital gains tax, reporting and deductions.

Key questions include:

Will you sell your U.S. home before or after becoming Spanish tax resident?
Will you rent it out?
Will you buy Spanish property before or after residency begins?
Will the property be owned individually, jointly or through an entity?
Are there mortgages or loans attached to the property?
Could imputed income, rental income or wealth tax issues arise?
Are records of purchase price, improvements and expenses complete?

For many clients, real estate timing is one of the most important pre-relocation planning areas because transactions are often large, visible and difficult to unwind.

10. What documentation should be collected before the move?

Good tax planning depends on good records.

Before relocating, gather and organize:

Passport travel history
Visa and immigration documents
Prior tax returns
Pay slips and employment agreements
Business ownership documents
Brokerage and bank statements
Retirement account statements
Cost basis reports
Real estate purchase documents
Mortgage statements
Trust, estate or partnership documents
Insurance contracts
Stock option or equity compensation documents
Records of gifts or inheritances
Prior foreign asset filings

It is also helpful to create a clear timeline showing expected arrival date, family move dates, property transactions, income events, business changes and planned distributions.

This timeline often becomes the foundation for the residency and tax analysis.

11. Which advisors need to coordinate?

A move from the United States to Spain may involve more than one professional.

Depending on the situation, coordination may be needed between Spanish tax counsel, U.S. tax preparers, immigration counsel, financial advisors, payroll providers, corporate accountants, estate planning attorneys and real estate professionals.

The goal is not to create unnecessary complexity. The goal is to prevent fragmented advice.

A U.S. advisor may understand U.S. reporting but not Spanish wealth tax. A Spanish advisor may understand Spanish residency but not U.S. citizenship-based taxation. A financial institution may provide investment advice without considering cross-border reporting. Pre-relocation coordination helps ensure that decisions are reviewed from both sides.

Final thoughts

Moving to Spain is more than a change of address. For internationally mobile individuals, it can be a change in tax residency, reporting obligations, asset exposure and long-term planning.

The most important step is to review the position before Spanish tax residency begins.

A practical pre-relocation tax checklist should answer four basic questions:

When could Spain consider you tax resident?
What income, assets and structures will move with you?
What Spanish and U.S. reporting obligations may apply?
What planning should be completed before the move?

Every relocation is different. A tailored review can help identify the tax issues that matter most, avoid unnecessary surprises and create a clearer path before moving to Spain.
