How pension tax relief works

The government tops up what you pay in. At the basic rate, every £80 you pay from your take-home pay becomes £100 in your pension. Higher-rate and additional-rate taxpayers can claim extra relief through their tax return. In this calculator, “your contribution” includes the basic-rate tax relief.

Frequently asked questions

What is the minimum workplace pension contribution?

Under automatic enrolment, the usual minimum is 8% of qualifying earnings in total: at least 3% from your employer, with the rest from you including tax relief. Many employers pay more, and some match extra contributions.

How much of my pension can I take tax-free?

Usually 25% of your pension can be taken tax-free, up to a lifetime maximum of £268,275 for most people. The rest is taxed as income when you take it.

Does this include the State Pension?

No. This calculator shows your private or workplace pension only. The State Pension is paid on top, based on your National Insurance record, and you can check your forecast on GOV.UK.
