For many British expats living in Spain, retirement planning quickly becomes more complex than simply drawing a pension. Different tax systems, changing residency status, currency exposure and evolving pension rules can all materially affect how retirement income is taxed and accessed.

One area that regularly raises questions is the use of a UK Self-Invested Personal Pension (SIPP) while living in Spain. Since direct transfers into many Spanish pension arrangements are often not practical or suitable for UK pension holders, SIPPs remain a common option for expats seeking flexibility and continued access to UK-regulated pension structures.

However, while a SIPP can offer advantages for internationally mobile retirees, there are also important cross-border considerations that should not be overlooked. The tax treatment in Spain may differ significantly from the UK, and decisions around withdrawals, transfers and contributions can have long-term implications for retirement income.

SIPPs Considerations for British Expats in Spain

A SIPP is a UK-regulated defined contribution pension that offers greater investment flexibility than many traditional workplace pensions. For expats, they can provide a practical way to retain pension arrangements within the UK regulatory framework while continuing to manage investments from overseas.

Many international SIPPs are specifically structured to support non-UK residents, often offering:

• Multi-currency capabilities
• Access to international investment options
• Cross-border administration support
• Consolidation of multiple UK pensions
• Flexible drawdown arrangements

For retirees receiving income in euros but holding pension assets in sterling, currency flexibility can also play an important role in long-term retirement planning.

That said, not all SIPP providers accept Spanish residents, and some may restrict services once a client leaves the UK. Before making any decisions, expats should carefully review provider terms, tax treatment and ongoing suitability.

The Spanish Tax Position Matters More Than Many Expect

One of the most common misunderstandings among British expats is assuming that UK pension tax treatment automatically applies in Spain.

This is not always the case.

While UK rules may allow elements of pension withdrawals to be taken tax-free, Spain can assess the same withdrawals very differently. Once you become tax resident in Spain, UK pension income is generally assessed under Spanish income tax rules (IRPF), with rates depending on total taxable income and the autonomous community in which you live.

This means that:

• A UK tax-free lump sum may still be taxable in Spain
• Large withdrawals could push you into higher tax bands
• Withdrawal timing may materially affect your net income
• UK PAYE withholding can create temporary cash-flow issues

As a result, pension planning for expats in Spain often becomes less about the pension itself and more about coordinating withdrawals efficiently across two tax systems.

Timing Your Move to Spain Can Affect Pension Taxation

The year in which you relocate to Spain can be particularly important.

Spain assesses tax residence on a calendar-year basis, while the UK tax year runs from April to April. If you move to Spain part-way through a year and subsequently become Spanish tax resident, pension withdrawals made during that same period may need to be considered under both UK and Spanish tax rules.

This can create unexpected outcomes if withdrawals are taken without considering:

• When Spanish tax residence officially begins
• Whether UK split-year treatment applies
• How Spain views pension income received during the transition year
• Whether UK tax has already been withheld

For many expats, careful sequencing of withdrawals before or after relocation can materially influence the overall tax position.

Understanding the Different Ways to Access a SIPP

UK pension rules currently allow access from age 55, rising to 57 from April 2028 unless protected pension ages apply.

The main options include:

Pension Commencement Lump Sum (PCLS)

Under UK rules, up to 25% of pension benefits may usually be withdrawn tax-free, subject to current lump sum allowance limits.

However, Spanish tax treatment can differ significantly. A withdrawal considered tax-free in the UK may still be treated as taxable pension income in Spain. This is one of the most important areas where expats often require specialist cross-border planning.

UFPLS Withdrawals

Uncrystallised Funds Pension Lump Sums (UFPLS) allow ad hoc withdrawals directly from uncrystallised pension funds.

Under UK rules:

• 25% is generally tax-free
• 75% is taxed as income

However, Spain may assess the entire payment as taxable income, potentially creating a very different outcome to what many retirees initially expect.

Flexi-Access Drawdown

Drawdown remains one of the most flexible retirement income options available to expats.

It allows retirees to:

• Keep pension assets invested
• Withdraw income gradually
• Potentially manage annual taxable income more efficiently
• Retain investment flexibility

For some expats in Spain, phased drawdown can offer greater control than taking large lump sums in a single tax year. The suitability of phased drawdown will depend on individual circumstances, objectives and the applicable tax treatment.

UK PAYE Withholding Can Still Apply

Even where the UK-Spain double tax treaty gives Spain primary taxing rights over private pension income, UK pension providers may still initially deduct PAYE tax.

This can occur because:

• The provider applies an emergency tax code
• HMRC has not processed treaty-relief requests
• The pension is being accessed for the first time
• Irregular withdrawals trigger standard PAYE treatment

In practice, this can temporarily reduce the net amount received until refunds or revised coding arrangements are processed.

For retirees relying on pension income for day-to-day living costs in Spain, this cash-flow issue can become significant if not anticipated in advance.

Should You Transfer Existing UK Pensions Into an International SIPP?

For some expats, consolidating pensions into an international SIPP may improve administration and retirement planning efficiency.

Potential benefits can include:

• Easier management of multiple pensions
• International investment flexibility
• Currency management options
• Simplified drawdown planning
• Continued UK regulatory oversight

However, transfers are not suitable for everyone.

Defined benefit pensions and safeguarded schemes may contain valuable guarantees, including:

• Inflation-linked income
• Guaranteed annuity rates
• Protected pension ages
• Enhanced death benefits
• Scheme-specific tax-free cash entitlements

Giving up these features can materially change retirement security and should never be treated lightly.

Common Pension Planning Mistakes Expats Make in Spain

Over the years, several recurring issues continue to affect British retirees moving to Spain.

These often include:

• Assuming UK tax-free cash remains tax-free in Spain
• Taking large withdrawals without modelling Spanish tax exposure
• Failing to review UK PAYE implications
• Continuing pension contributions without confirming UK eligibility
• Ignoring currency risk when income is needed in euros
• Transferring safeguarded pensions without fully understanding the guarantees being lost
• Failing to review pension strategy during the year of relocation

Cross-border pension planning is rarely just about investment performance. The structure, timing and taxation of withdrawals can often have a greater impact on long-term retirement outcomes than investment returns alone.

The Importance of Cross-Border Financial Planning

Retiring internationally can offer lifestyle benefits, but it also introduces financial complexity that many retirees underestimate.

The interaction between UK pension legislation, Spanish tax rules, residency laws and currency exposure means pension decisions should ideally be reviewed within a broader cross-border financial planning framework.

At Blacktower Financial Management, we have spent over 40 years supporting internationally mobile individuals navigate the practical and financial realities of life abroad. For British expats in Spain, understanding how pensions are taxed, accessed and structured across borders can play a critical role in supporting long-term retirement objectives.

As with all financial planning, suitability depends on individual circumstances, residency status and long-term goals.
