Moving to Spain? Tax strategies to protect your UK wealth

Spain continues to attract large numbers of British expats, particularly in Alicante, Málaga, and across Andalucía, thanks to its climate, lifestyle, and lower cost of living. However, while the move is often lifestyle-led, the financial implications are far more complex.

Relocating to Spain introduces a new tax framework, additional reporting obligations, and cross-border considerations that do not exist in the UK, making cross-border wealth planning and advisory services a key part of any well-structured relocation strategy.

Once you become a Spanish tax resident, the Agencia Tributaria applies a global approach to your finances. This means your worldwide income and assets fall within the Spanish tax system, which can significantly change how your UK savings, pensions, property, and investments are treated.

Without proper planning, the benefits of relocating can quickly be eroded by unexpected tax exposure, reporting requirements, and ongoing administrative complexity.

These five essential considerations outline the key areas UK expats need to understand before moving to Spain.

1. Tax residency: When Spain considers you resident

Tax residency is not only based on where you spend your time, but where your life is effectively based. In Spain, you are generally treated as a tax resident if you meet either of the following conditions:

• You spend more than 183 days in Spain during a calendar year
• Your centre of vital interests is in Spain, meaning your spouse, dependent children, or main business activities are based there

Once you meet either test, Spain can tax you on your worldwide income, including UK rental income, dividends, and pension income.

2. ISAs in Spain: Why UK tax-free savings lose their protection

The Individual Savings Account (ISA) is a cornerstone of UK tax planning, offering tax-free growth and dividends. However, Spain does not recognise ISA tax benefits.

Once you become a Spanish tax resident, any income or capital gains generated within an ISA are fully taxable.

In addition, if your total overseas assets exceed €50,000, they must be declared on the Modelo 720 information return, Spain’s foreign asset reporting requirement.

3. UK pensions in Spain: How taxation changes on withdrawal income

Under the UK–Spain Double Taxation Agreement, most private and occupational pensions are taxed only in the country where you are a tax resident.

• The 25% lump sum: While this is typically tax-free in the UK, Spain treats it as regular income. Depending on your total income and the region where you live, this may be taxed at progressive rates of 45% or higher
• SIPPs: Withdrawals from Self-Invested Personal Pensions are generally taxed at Spain’s progressive income tax rates. This makes the timing and structure of your drawdowns an important part of your relocation and income planning strategy.

4. Selling your UK property after moving to Spain

A common pitfall arises when selling a UK property after relocating to Spain. In the UK, Principal Private Residence (PPR) relief often eliminates Capital Gains Tax (CGT) on your main home. However, if you are already a Spanish tax resident when the sale completes, Spain may tax the gain under its own capital gains rules.

Pro tip: Where possible, complete the sale of major UK assets before becoming a Spanish tax resident to help reduce potential cross-border capital gains tax exposure.

5. Spanish Capital Gains Tax rates for expats

Spain applies a tiered tax system to savings and capital gains. For 2026, the national rates are structured as follows:

• 19% on the first €6,000
• 21% on €6,001 to €50,000
• 23% on €50,001 to €200,000
• 27% on gains above €200,000

These rates apply to investment gains and savings income for Spanish tax residents, meaning larger portfolios can quickly move into higher tax bands depending on the size and timing of disposals.
