What is the difference between 'net pay' and 'relief at source' pension contributions?

Full answer

The method your workplace pension scheme uses to give you tax relief -- net pay or relief at source -- can affect both how much relief you receive automatically and, for some low earners, whether you get any tax relief at all. **How net pay arrangements work** Under a net pay arrangement, your pension contribution is deducted from your gross salary BEFORE Income Tax is calculated on your pay. This means you automatically receive tax relief at your full marginal rate (20%, 40%, or 45% depending on your income) with no separate claim needed, since the contribution simply reduces the taxable pay your Income Tax is calculated on in the first place. **How relief at source works** Under relief at source, your pension contribution is deducted from your NET (after-tax) pay, and the pension provider then claims basic-rate tax relief (20%) from HMRC and adds it to your pension pot automatically -- so a £80 contribution from your net pay becomes £100 in your pension after the provider claims the relief. If you are a higher or additional-rate taxpayer, you do not automatically receive the extra relief above basic rate; you must claim this yourself, usually through your Self Assessment tax return or by contacting HMRC directly, and it is normally paid to you as extra relief rather than added directly to your pension pot. **Why this matters for low earners specifically** A well-known quirk affects low earners who pay no Income Tax at all (earning below the £12,570 Personal Allowance) but are enrolled in a net pay scheme -- because net pay arrangements only provide relief by reducing taxable income, someone with no tax liability in the first place gets no tax relief benefit from a net pay scheme, and effectively pays the full, un-relieved contribution. Under relief at source, by contrast, even a non-taxpayer still receives the 20% basic-rate top-up added to their pension automatically, because the provider claims it directly from HMRC regardless of the member's own tax position. **Government action on the low-earner anomaly** This discrepancy has been recognised as unfair to low earners (who are disproportionately women and part-time workers) in net pay schemes, and the government has introduced arrangements for eligible low earners in net pay schemes to receive a top-up payment after the end of the relevant tax year to compensate for the relief they would otherwise miss out on -- check whether you may be eligible if your earnings are below the Personal Allowance and your employer uses a net pay scheme. **Worked example** A higher-rate taxpayer contributes £4,000 a year to a relief-at-source workplace pension. The provider claims 20% basic-rate relief, adding £1,000 to make the total contribution £5,000 in the pension. Because they pay tax at 40%, they are entitled to a further £1,000 of higher-rate relief, which they must claim through Self Assessment or by contacting HMRC -- if they never make this claim, they simply lose out on that extra relief, even though they were entitled to it. **Practical tip** Check which method your workplace pension scheme uses (your payslip or scheme documentation should confirm this), and if you are a higher or additional-rate taxpayer in a relief-at-source scheme, make sure you actively claim the extra relief you are due each year -- it is not paid automatically.
