Pension Contributions & Tax Relief: UK Guide 2025

Understanding pension tax relief is essential for retirement planning. This guide explains how pension contributions work and how to maximize your tax benefits.

How Pension Tax Relief Works

When you contribute to a pension, the government adds tax relief to your contribution. The amount depends on your income tax rate.

Tax Relief Rates

Income Tax Rate	Tax Relief Rate	Example Contribution
Basic Rate (20%)	20%	£100 contribution = £125 in pension
Higher Rate (40%)	40%	£100 contribution = £166.67 in pension
Additional Rate (45%)	45%	£100 contribution = £181.82 in pension

Annual Allowance

The maximum you can contribute to pensions each year with tax relief:

Standard Annual Allowance: £60,000 (2025/26)
Tapered Annual Allowance: Reduces for high earners (£260,000+)
Minimum Tapered Allowance: £10,000

High Earners Taper

If your adjusted income exceeds £260,000:

Allowance reduces by £1 for every £2 over £260,000
Minimum allowance: £10,000
At £360,000+, your allowance is £10,000

Lifetime Allowance

Note: The Lifetime Allowance was abolished in April 2024. There's no longer a limit on pension savings, but there are limits on tax-free lump sums.

Salary Sacrifice Explained

Salary sacrifice reduces both income tax AND National Insurance:

Example: £50,000 Salary, 5% Pension Contribution

Without Salary Sacrifice:

Pension contribution: £2,500
Income tax saved: £500 (20%)
NI saved: £0
Total tax saving: £500

With Salary Sacrifice:

Pension contribution: £2,500
Income tax saved: £500 (20%)
NI saved: £200 (8%)
Total tax saving: £700
