How Pension Contributions Work in the UK

Complete guide to understanding pension contributions, tax relief, and how they affect your take-home pay in the UK for the 2025/26 tax year.

What Are Pension Contributions?

Your pension pot is built from three sources: your own contributions, employer contributions, and government tax relief.

How Tax Relief Works

• Basic rate (20%): £80 contribution costs you £80 — HMRC adds £20 tax relief, putting £100 in your pension.
• Higher rate (40%): You can claim back an additional 20% through self-assessment.
• Additional rate (45%): You can claim back an additional 25% through self-assessment.

Employer Contributions

Under auto-enrolment, your employer must contribute at least 3% of qualifying earnings. Many employers offer matching schemes where they increase their contribution when you increase yours.

Types of Pension Contributions

• Standard (Relief at Source): Contributions come from your net pay. Your pension provider claims 20% basic rate relief automatically.
• Salary Sacrifice: Your salary is reduced before tax, so you save income tax and National Insurance on the sacrificed amount.

Annual Allowance

The maximum you can contribute with tax relief is £60,000 per year (or 100% of your earnings, whichever is lower). High earners with adjusted income above £260,000 face a tapered allowance as low as £10,000.
