Tax on Life Insurance Policy Gains

Introduction

Gains from life insurance policies can trigger a tax charge known as a chargeable event. While the insurance company often deducts basic rate tax automatically, higher and additional rate taxpayers may face further liability. This article explains when gains become taxable, how to report them, and the special considerations for offshore policies.

What Are Chargeable Events?

A chargeable event occurs when you make a gain from a life insurance policy in specific circumstances. The most common chargeable events include:

• Full surrender – when you cash in the entire policy
• Partial surrender – when you withdraw money that exceeds the cumulative 5% allowance (explained below)
• Policy maturity – when the policy reaches the end of its term
• Death of the life insured – though this rarely produces a taxable gain
• Assignment for money or money's worth – when you sell or transfer the policy for value

Not all life insurance policies can produce chargeable gains. Qualifying policies, term assurance policies, and pension policies are exempt from these rules.

The 5% Withdrawal Allowance

You can withdraw up to 5% of the premiums paid each year without triggering an immediate tax charge. This allowance is cumulative, meaning any unused allowance from previous years carries forward.

If you withdraw more than the cumulative 5% allowance, the excess creates a chargeable event gain. When you eventually surrender or mature the policy, the insurer calculates the total gain and deducts any amounts already assessed under partial surrenders.

Who Is Taxed on the Gain?

The person liable for tax depends on who held the policy rights when the chargeable event occurred:

• If you owned the policy when you surrendered it or it matured, you pay the tax
• If you assigned the policy to someone else for value, the assignee is usually liable
• For jointly held policies, each owner is taxed on their share of the gain

Special rules apply for policies held in trust. The trustees may be liable, or in some cases the settlor (the person who created the trust) is taxed on the gain.

How Gains Are Taxed

Life insurance gains are treated as savings income and taxed at your income tax rates. The gain is added to your other income for the tax year, and tax applies to the amount that falls into higher or additional rate bands.

For 2025/26, the rates are:

• Basic rate (20%): already treated as paid by the insurance company
• Higher rate (40%): you pay an additional 20%
• Additional rate (45%): you pay an additional 25%

Because basic rate tax is treated as paid, you only owe further tax if you're a higher or additional rate taxpayer. If you're a basic rate taxpayer throughout, there's no additional tax to pay.

Top Slicing Relief

Top slicing relief prevents a single large gain from pushing all your income into higher tax bands unfairly. This relief is particularly valuable for policies held for many years.

The calculation works as follows:

1. Divide the gain by the number of complete years the policy was held

2. Add this "slice" to your other income to determine what rate of tax applies

3. Multiply the tax on one slice by the number of years

4. Compare this with the tax that would apply without slicing

You pay whichever amount is lower. Your insurance company or accountant can help calculate this, as the computation can be complex. Top slicing relief is given automatically when you report the gain correctly on your Self Assessment tax return.

Deficiency Relief

If you made a loss on your policy, you cannot offset it against other income or capital gains. However, deficiency relief allows you to offset losses against gains from other life insurance policies in the same tax year or from policies that mature in future years.

To claim deficiency relief, you must keep detailed records and report the loss on your tax return.

Reporting Gains on Your Tax Return

You must report chargeable event gains on your Self Assessment tax return, even if no additional tax is due. The insurance company will send you a chargeable event certificate showing:

• The amount of the gain
• The number of years the policy was held (for top slicing relief)
• Whether any basic rate tax has been treated as paid

You enter these figures in the 'Gains from life insurance policies and life annuities' section of your return. For UK policies, this appears on the main SA100 return and the SA101 additional information pages if needed.

Special Rules for Offshore Policies

Foreign life insurance policies follow similar rules but with important differences. Offshore policies issued by insurers based outside the UK can offer investment flexibility, but they come with stricter tax treatment.

For offshore policies:

• No basic rate credit: Unlike UK policies, there's no treated as paid basic rate tax credit. You pay tax on the full gain at your marginal rates (20%, 40%, or 45%).
• Time apportionment: If you were UK resident for only part of the period you held the policy, the gain may be apportioned to reduce the taxable amount.
• Different reporting: You report offshore policy gains separately on your tax return using the foreign section.

The lack of basic rate credit makes offshore policies less tax-efficient for UK residents compared to UK-based policies, unless you were non-resident for a significant part of the policy term.

When to Seek Advice

Life insurance taxation involves complex calculations, especially when top slicing relief or offshore policies are involved. You should speak to your accountant before:

• Surrendering a long-held policy
• Making withdrawals that might exceed the 5% allowance
• Assigning a policy to someone else
• Receiving a chargeable event certificate showing a large gain

Planning the timing of surrenders across tax years or using the 5% allowance strategically can reduce your tax bill significantly.
