About PensionTaxReliefCalculator.co.uk

What this site is for

Use the calculators to get a fast, private estimate of your relief and net contribution cost. The suite includes the main pension tax relief calculator, the higher-rate relief calculator, the relief at source calculator, the salary sacrifice calculator, the net pay arrangement calculator, the annual allowance checker and the SIPP tax relief calculator. See the full list of calculators.

The guides answer specific questions quickly, for example "how much tax relief do I get on a £10,000 pension contribution as a higher-rate taxpayer?" or "how much of a £1,000 gross contribution comes out of my own pocket?". The site is designed for anyone paying into a workplace or personal pension who wants to understand their relief before they contribute or before they file a Self Assessment claim. For a decision on your own circumstances, always check GOV.UK and HMRC, or speak to a regulated financial adviser.

What we cover

• How pension tax relief works — why a £1,000 gross contribution costs a basic-rate taxpayer £800, and how relief is added to your pot or reduces your tax bill depending on your scheme.
• Relief at source vs net pay vs salary sacrifice — the three ways contributions are handled, who gets relief automatically, and why the same contribution can have a different net cost under each method.
• Claiming higher and additional rate relief — how 40% and 45% taxpayers claim the extra 20% or 25% through Self Assessment or a change to their PAYE tax code, with worked examples.
• The annual allowance — the £60,000 limit on tax-relieved contributions, how employer and employee contributions both count, and what happens if you exceed it.
• Tapered and money purchase annual allowance — how the allowance tapers for high earners above the adjusted income threshold, and the £10,000 MPAA that applies once you flexibly access a pension.
• Carry forward — how unused allowance from the previous three tax years can let you contribute more than £60,000 in a single year while keeping relief.
• Scottish taxpayers — how Scottish income tax rates change the extra relief you can claim, even though providers still reclaim relief at the 20% basic rate.

Editorial approach

Every calculator and guide is written in plain British English and reviewed against current HMRC and GOV.UK pension guidance for the active tax year. We prioritise factual accuracy, transparent assumptions and pages that genuinely help a reader take the next step, not pages that restate definitions without helping anyone act.

We show our workings. Where a calculation is simplified or an assumption is made, it is stated on the page and explained in full on the methodology page. Our editorial standards cover how we write, review and update content, and the official sources we check against.

The site is free to use and funded by advertising. That never affects the figures our calculators produce or the guidance we give. This site provides general information and estimates only. It is not regulated financial advice, tax advice or a personal recommendation.

How the site is maintained

• Relief rates, income tax bands and the annual allowance are updated when HMRC confirms the figures for each new tax year.
• Guides and calculators are reviewed at each Budget and Autumn Statement, and whenever HMRC changes its pension tax relief guidance.
• Pages are updated when readers report confusing assumptions, unclear wording or outdated figures.
• We do not publish pages without practical value for a UK pension saver audience.
