What is pension tax relief?

For every £100 you contribute to a pension, the government adds £25 (20% basic rate), making your contribution effectively £125 in the pension at a personal cost of only £100. Higher rate taxpayers claim the additional 20% (£25 more) via self-assessment.

What is relief at source?

Pension provider claims 20% basic rate relief from HMRC and adds it to your pension pot. You pay the net amount: £80 personal contribution becomes £100 in the pension. Higher rate taxpayers claim additional 20% via self-assessment.

What is net pay arrangement?

Employer deducts pension contributions from gross pay before calculating income tax (PAYE), meaning you contribute from pre-tax income. Tax relief is automatic for all taxpayers. Low earners below the personal allowance get no relief (a known unfairness being addressed).

Who benefits more from relief at source?

Non-taxpayers and basic rate taxpayers benefit equivalently from both methods. Higher rate taxpayers benefit equally but must actively claim via self-assessment under relief at source. Non-taxpayers only get relief under relief at source, not net pay.

How much tax relief can higher rate taxpayers claim?

Higher rate (40%) taxpayers: 40% total relief on pension contributions. For £10,000 pension contribution: £2,000 claimed by provider (relief at source) + £2,000 via self-assessment = £4,000 total government contribution. Effective cost: £6,000.
