The 10 Most Expensive Pension Mistakes Expats Make

Pension decisions are among the most consequential financial choices of a lifetime — and many of the most important ones are irreversible. UK expats face a specific set of pitfalls that combine the complexity of cross-border pension rules with the vulnerability of being geographically distant from UK institutions and regulated advisers.

This guide identifies the 10 most expensive mistakes UK expats make with their pensions — and what to do instead.

This guide is for information purposes only and does not constitute financial, tax or legal advice.

Mistake 1: Transferring a DB Pension Without Regulated Advice

The most costly and irreversible mistake. A defined benefit pension — from the NHS, teachers' pension, civil service, or a previous private sector employer — provides guaranteed, index-linked income for life. The actuarial value of this guarantee almost always exceeds the Cash Equivalent Transfer Value that the scheme offers.

What typically goes wrong: An expat is approached (often by someone in their new country) with a compelling pitch about "freedom", "control", or "unlocking" their pension. They transfer without understanding what they are giving up. Years later, in retirement, the loss becomes painfully clear.

What to do instead: Leave DB pensions deferred unless you have received explicit regulated advice from an FCA-authorised pension transfer specialist who has produced a full Transfer Value Analysis. The default answer is to keep it. See our pension transfer advice guide.

Mistake 2: Not Tracing Lost Pensions

The average UK worker changes employers several times. Each move may leave a deferred pension pot with a previous employer's scheme. Many expats have pensions from the 1990s or 2000s sitting in old workplace schemes — generating statements to addresses that no longer exist.

What typically goes wrong: A pension that could be worth £30,000–£200,000 is simply forgotten. The member reaches retirement and the pension has never been claimed or traced.

What to do instead: Use the government's Pension Tracing Service, check old payslips and P60s, and contact all previous employers. Update your address with every scheme you find.

Mistake 3: Paying the Overseas Transfer Charge Unexpectedly

The OTC is a 25% charge on transfers to QROPS. It applies unless the residency match exemption (or another limited exemption) is available. Expats who don't confirm the OTC position before transfer can face a 25% deduction from their transfer value.

What typically goes wrong: An expat in one country transfers to a QROPS registered in a different country (perhaps following advice that was accurate before October 2024 but became incorrect after the EEA exemption was removed). The OTC is deducted, and the member has only 75% of their transfer value in the QROPS.

What to do instead: Confirm the OTC position with an adviser before initiating any QROPS transfer. Verify the ROPS list status of the receiving scheme immediately before transfer. See our pension transfer tax implications guide.

Mistake 4: Not Updating Your Address with Pension Providers

This seems small but causes serious problems. Pension statements, discharge forms, transfer confirmations, and scheme communications go to the address on record. An old UK address means you lose contact with your pension entirely.

What typically goes wrong: Years after moving abroad, an expat tries to access or transfer a pension and discovers the provider holds a years-old address. The account may have been put into a restricted state. Discharge forms for transfers were sent to the wrong address and expired. Recovery takes months.

What to do instead: Update your address with every pension provider, and your employer if they administer your pension, within the first month of moving abroad. Use an email address you actively monitor.

Mistake 5: Triggering the MPAA Before Contributions Are Complete

The Money Purchase Annual Allowance (MPAA) reduces the contribution limit from £60,000 to £10,000 per year once you take any flexible drawdown from a pension. Many expats trigger the MPAA prematurely — taking a small drawdown payment without realising the consequence.

What typically goes wrong: An expat needs cash and takes a small income from their SIPP. This triggers the MPAA. They later return to UK employment or receive a large UK bonus and want to make significant SIPP contributions — but are now limited to £10,000 per year.

What to do instead: If you might need to contribute significantly to a SIPP in future years, do not take any drawdown income until that contribution phase is complete. Take PCLS (tax-free cash) if needed — this does not trigger the MPAA. See our SIPP annual allowance guide.

Mistake 6: Choosing a SIPP Platform That Won't Accept You

Not all SIPP platforms accept members in all countries. US persons face FATCA restrictions. Some platforms have restricted their country acceptance lists. An expat who transfers to a platform that later restricts access for their country of residence finds their pension frozen or inaccessible.

What typically goes wrong: A SIPP platform changes its terms and stops accepting residents of a specific country. The member cannot manage their account, execute investment instructions, or transfer out without significant difficulty.

What to do instead: Before transferring, confirm explicitly that the platform accepts members resident in your country — get the confirmation in writing. Understand the platform's policy on country of residence changes.

Mistake 7: Missing the 5-Year Carry Forward Window

Expats with unused annual allowance from years as a non-resident can often make large, tax-relieved contributions using carry forward when they return to UK employment or receive large UK income. This window is limited to three previous tax years.

What typically goes wrong: An expat with three years of unused £60,000 allowances returns to UK employment and misses the opportunity to contribute £240,000 in a single year — potentially saving £80,000+ in income tax at the higher rates.

What to do instead: When your employment situation changes and you have UK earnings, review your carry forward position before the tax year ends and consider whether a large SIPP contribution makes sense. See our annual allowance guide.

Mistake 8: Falling Victim to a Pension Scam

Pension scams have cost UK savers billions. Expats are disproportionately targeted — they are geographically distant from UK institutions, exposed to overseas-based promoters, and may be unfamiliar with what legitimate pension advice looks like.

What typically goes wrong: An expat is approached (via social media, an expat forum, or a social connection) with an investment opportunity or pension review that leads to a transfer to a fraudulent scheme. The money is lost.

What to do instead: Never act on unsolicited approaches about your pension. Verify any firm on the FCA register before engaging. Seek regulated, fee-based independent advice. Our pension scams guide covers the warning signs in full.

Mistake 9: Not Claiming the DTA Exemption from UK Withholding Tax

Private pension income paid to a non-UK resident is subject to UK withholding tax at source unless you have claimed the DTA exemption using HMRC form DT-Individual. Many expats receive net-of-tax pension payments without realising they could receive the income gross (paying only their country's tax).

What typically goes wrong: An expat receives SIPP drawdown payments with 20% UK income tax deducted at source. They then pay local tax on the gross equivalent as well. Although double tax relief is available, the administrative burden means overpayment often persists for years.

What to do instead: Submit DT-Individual to HMRC as soon as you have established non-UK residency and are drawing pension income. Reclaim any excess UK withholding tax through a self-assessment return.

Mistake 10: Not Planning State Pension Contributions

The UK State Pension requires 35 qualifying years of National Insurance contributions for the full amount (£11,502/year in 2026). Many expats have gaps in their NI record that could be filled through voluntary Class 2 or Class 3 contributions — potentially at low cost.

What typically goes wrong: An expat reaches State Pension age and receives significantly less than the full amount due to gaps in their NI record. Class 3 voluntary contributions, which could have filled the gaps at £824/year (2026), were not made. The cost of the missed contributions over a 20-year retirement is substantial.

What to do instead: Check your NI record via the HMRC personal tax account. Calculate how many qualifying years you have and how many gaps can be filled affordably. The deadline for filling gaps from 2006 onwards was extended to April 2025 — check current deadlines for any remaining voluntary contribution opportunities.
