An Expat’s Guide to Tax-Efficient Retirement Withdrawal Strategies

Implementing effective tax-planning methods may significantly reduce the tax burden on your retirement withdrawals and preserve more of your wealth. This guide will explore the best tax-efficient retirement withdrawal strategies and illustrate how to apply them to maximise your retirement income.

Types of Retirement Income Sources Available to UK Expats

The most tax-efficient retirement withdrawal strategies for your specific circumstances will depend on the type of retirement account you hold. UK expats typically receive their retirement income from the following sources:

1. State pensions
2. Workplace pensions
3. Personal pensions
4. Investment and savings accounts

State Pensions

The UK government provides the state pension once you reach age 66 – the current standard state pension age. However, this is scheduled to gradually rise to 67 between 2026 and 2028, depending on your date of birth. Further increases to age 68 are under review. You accrue these pension benefits by contributing to the National Insurance, and the income you receive in retirement depends on the amount you contribute.

There are two types of state pensions in the UK:

A qualifying year for National Insurance purposes is one in which at least one of the following criteria is met:

• You worked and made National Insurance contributions.
• You paid voluntary National Insurance contributions.
• You received National Insurance credits due to specific circumstances such as unemployment or illness.

If you’ve lived or worked overseas but resumed voluntary National Insurance contributions, you may still qualify for a state pension upon repatriation.

In case you have less than 10 qualifying years, you may be eligible for the UK state pension if you contributed to a state pension in the European Economic Area (EEA), or another country with a social security agreement with the UK, like the US, New Zealand, and the Isle of Man.

Workplace Pensions

Your employer in the UK must establish a workplace pension to provide you with retirement benefits. They can contribute to two types of workplace pensions:

1. Defined benefit (DB): Known as a final salary, this pension provides stable income during retirement, and the amount depends on your salary and years of employment.
2. Defined contribution (DC): This pension allows both you and your employer to make contributions, which are then invested in various assets, like stocks and bonds, to grow your retirement savings. The pension benefit you’ll receive in retirement is based on the contribution amount and investment performance.

Since the accrual of retirement savings in DC schemes depends on investment performance, the income is not guaranteed.

Meanwhile, DB schemes provide guaranteed retirement income, but the amount may be lower than what you could accrue in a DC scheme if your assets performed well.

Personal Pensions

A personal pension is typically a DC scheme you set up independently to save funds for retirement while benefiting from flexible contributions and wide investment options.

They’re managed by banks, investment firms, and insurance companies, and they provide pension income based on your contributions and investment performance.

Self-invested personal pensions (SIPPs) are a common type of personal pensions among UK expats as they offer greater investment flexibility and various tax advantages.

Additionally, you may utilise SIPPs as pension consolidation vehicles to centralise your retirement savings and manage them more efficiently, regardless of where you reside.

Investment and Savings Accounts

Apart from various types of pensions, UK citizens and expats may leverage other sources to increase retirement savings, including the ones outlined below:

While ISAs are only available to UK tax residents, offshore bonds and GIAs (depending on the provider) are suitable for UK expats and foreign residents in the UK. Therefore, the taxation of the latter two options will depend on your tax residency.

If you open an ISA as a UK resident and become a non-resident afterwards, you can still retain the account. However, you can’t contribute to it until you reclaim your UK tax residency.

Financial advisers at Titan Wealth International can assist you with choosing a retirement savings account that meets your financial goals, taking your residency and personal circumstances into consideration.

Taxation of Retirement Accounts in the UK

Depending on the source of your retirement savings, withdrawals may be subject to the following UK taxes:

1. Income tax
2. Inheritance tax
3. Capital gains tax

Income Tax

Tax residents are liable for income tax on pension withdrawals in the UK if their total annual taxable income exceeds the tax-free personal allowance threshold of £12,570. Taxable income includes:

• State pension
• Workplace and personal pensions
• Income from investment and savings accounts

You’re allowed to withdraw up to 25% of your retirement savings as a tax-free lump sum from any pension, without affecting your personal allowance. The maximum tax-free withdrawal amount across all pensions combined is £268,275. These rules are applicable upon reaching the standard retirement age in the UK, which is currently 55, but will rise to 57 in 2028.

Any pension funds exceeding the applicable allowances upon withdrawal are taxed at your marginal income tax rate, ranging from 20% to 45%.

If you’re accumulating retirement savings in a GIA or an offshore bond, the accrued interest is subject to income tax if it exceeds the personal savings allowance (PSA), which equals:

1. £1,000 for basic 20% rate taxpayers
2. £500 for those in the higher 40% tax rate band

The additional-rate taxpayers—those with income exceeding £125,140—don’t qualify for PSA.

If you hold any retirement savings in an ISA, withdrawals are generally free from UK income tax. Nevertheless, certain types of ISAs, such as Lifetime ISAs, include a 25% charge if you withdraw or transfer funds before the age of 60.

Your tax obligations will differ if you’re a UK non-resident. For instance, non-residents aren’t taxed on most types of UK-sourced investment income (including income from GIAs), but may be liable for tax in their country of residence.

Similarly, your offshore bond gains are taxed upon withdrawal in the jurisdiction where you are a resident, meaning you may be exposed to lower tax rates if you live in a country with a more favourable tax regime. Still, withholding tax on dividends and interest may apply.

Assignment of an offshore bond to your spouse can retain time-apportionment relief based on the original policyholder’s UK residence history – allowing for continued tax efficiency after transfer.

Additionally, non-recoverable withholding tax may apply on offshore bond income for UK non-residents, depending on the jurisdiction.

Inheritance Tax

UK pensions aren’t subject to inheritance tax (IHT) as they are not considered a part of your estate. However, from 6 April 2027, DB and DC pensions will become liable for IHT of 40% as pension death benefits will be incorporated into the estate. Since transferring up to £325,000 of the estate to your beneficiaries doesn’t incur tax liability, only the amount exceeding the threshold will be taxed at 40%.

Retirement income sources like GIA and offshore bonds form a part of your estate upon death, making them liable for IHT. However, you can place the bond or the GIA in a bare trust to protect it from IHT.

In these trusts, assets are held in the trustee’s name and directly transferred to the beneficiary. The trust is exempt from IHT provided you survive for seven years after transferring the GIA or an offshore bond.

ISAs are also considered a part of your estate and are subject to IHT. However, if the beneficiary is your spouse or civil partner, they’re exempt from IHT.

Capital Gains Tax

UK pensions, ISAs, and offshore bonds are free from capital gains tax (CGT). Still, if you’re accruing retirement benefits in a GIA, you will be liable for CGT upon selling stocks, bonds, funds, and other underlying assets.

Each tax year, you receive an Annual Exempt Amount allowance free of CGT. For the tax year 2025/26, the limit is £3,000. Any chargeable gains exceeding the threshold are subject to CGT at the following rates:

• 18% for basic rate taxpayers
• 24% for higher and additional rate taxpayers

GIAs that pay out cash dividends are also subject to dividend tax in the UK if they exceed the £500 tax-free allowance and if your annual taxable income is higher than £12,570. The dividend amounts exceeding the allowance are taxed at the following rates:

1. Basic rate taxpayers: 8.75%
2. Higher rate taxpayers: 33.75%
3. Additional rate taxpayers: 39.35%

Tax-Efficient Withdrawal Strategies for Optimising Tax Liability

While you may not be able to avoid taxation of your retirement income withdrawals altogether, implementing tax-efficient strategies can ensure you optimise your tax liability and maximise the value of your savings.

The most tax-efficient retirement withdrawal strategies include the following:

1. Maximising the tax-free lump sum
2. Utilising the four-box principle
3. Leveraging reliefs and allowances
4. Opting for a flexible drawdown

Maximising the Tax-Free Lump Sum

The primary tax reduction strategy for pension withdrawals is to utilise your tax-free lump sum. The table below outlines the amount you can withdraw free of tax depending on the value of your pensions:

While the usual tax-free lump sum allowance is 25% of your pension savings, the percentage in the last example is 13.4% due to the Lump Sum Allowance (LSA) limit, which equals £268,275.

The previous Lifetime Allowance (LTA) threshold of £1,073,100 allowed for tax-efficient withdrawals of larger pension amounts. This was abolished in April 2024 and replaced by the Lump Sum Allowance (LSA), currently set at £268,275.

If your pension exceeds the limit under the new LSA, you should consider redirecting your additional savings to tax-efficient vehicles like offshore bonds and ISAs.

Utilising the Four-Box Principle

The four-box principle refers to minimising the taxation of your retirement income by accruing funds in several accounts with diverse tax treatments.

These include your pension, an ISA, a GIA, and an offshore bond. If you combine income from these sources when withdrawing your retirement savings, you may reduce or even legally avoid taxes.

For instance, a couple with £2 million invested across multiple accounts can withdraw around £85,000 per year free of tax in retirement, assuming they leverage all the available allowances. Refer to the table below for more details:

While pensions, including SIPPs, are taxed as income on withdrawal if they exceed the 25% lump sum allowance, each individual has a personal allowance of £12,570, meaning the couple could access £25,140 free of tax.

Offshore bonds allow you to withdraw 5% of the initial investment annually without immediate tax, resulting in a tax-deferred sum of £12,500. Note that these withdrawals will be taxed upon bond surrender.

Meanwhile, ISAs are free from income and capital gains tax upon withdrawal. Assuming the couple plans to take £85,000 in retirement income annually, they’d withdraw a total of £27,360 per year.

In case of GIAs, a couple can leverage their combined CGT allowance of £6,000 to withdraw up to £150,000 without tax implications. At an assumed return rate of 4%, their portfolio would earn £20,000 in a year, of which 30 (£6,000) can be crystallised tax-free using the allowance.

Crystallisation entails realising gains through the sale of assets, but the sale must represent a proportional amount of the entire portfolio—it’s not possible to crystallise just the gain.

Therefore, they must sell 30% of the total portfolio (£150,000), £6,000 of which is the gain and £144,00 the return of capital.

Since the return of capital isn’t subject to taxes, this transaction wouldn’t trigger CGT. However, for sustainability reasons, they may choose not to maximise the allowance and access only £20,000 per year.

Leveraging Reliefs and Allowances

Using all the available reliefs and allowances ensures you preserve as much of your retirement income as possible. Besides the tax-free lump sum, some of the allowances you can leverage include:

• The Personal Savings Allowance: This is a sum of up to £1,000 or £500, applicable to chargeable gains from offshore bonds and GIAs.
• The dividend allowance: Refers to a relief amount of £500, relevant to cash dividends from GIAs.
• Top slicing relief: Available for offshore bonds, it allows you to split the taxation of the gains based on the number of policy years you held the bond to avoid crossing into a higher tax bracket upon surrender.
• Time apportionment relief: It allows expatriates and repatriates holding offshore investments to reduce UK taxation of chargeable gains accrued while they were UK non-residents.

Opting for a Flexible Drawdown

Besides using lump sum allowances and splitting withdrawals between various sources, you can opt for a phased approach when withdrawing your retirement benefits to minimise tax exposure.

This strategy consists of regularly withdrawing smaller amounts to remain in the lowest income tax bracket. To maximise investment growth, you can also reinvest the withdrawn funds into tax-efficient instruments like offshore bonds.

Another strategy is to withdraw your pension as a flexible drawdown. This approach allows you to access your retirement savings when needed, while retaining the remaining funds in chosen investments.

With this strategy, you will maintain the growth of your funds while preserving the ability to access them or convert them into guaranteed income by purchasing an annuity.
