Pension tax relief explained (2026/27)

Pension contributions are one of the most tax-efficient uses of money available to UK taxpayers. Every pound you contribute to a registered pension scheme is topped up by the government through tax relief. The amount of relief — and how you receive it — depends on how your pension is set up and which income tax rate you pay.

1. How pension tax relief works

When you save into a pension, the government adds money on top of your contribution. The basic principle: you contribute from after-tax income and the government returns the income tax you paid on that amount.

Basic-rate taxpayer example (England, 20%):

• You want £100 in your pension
• You contribute £80 net
• Your provider claims £20 from HMRC (the 20% basic-rate relief)
• Your pension pot receives the full £100

Higher-rate taxpayer (40%):

• You contribute £80 net via Relief at Source
• Provider claims £20 → pot = £100
• You claim an additional £20 via Self Assessment → total relief = £40
• Net cost to you: £60 for £100 in the pot

Additional-rate taxpayer (45%):

• Net cost: £55 for £100 in the pot (20% via provider, 25% via Self Assessment)

2. Three methods of delivering relief

| Method | How it works | Who gets NI savings? | Relief delivery | |---|---|---|---| | Relief at Source (RAS) | You pay 80%; provider claims 20% from HMRC | No (NI already paid) | Basic rate automatic; higher/additional via SA | | Net Pay | Full gross deducted before tax calculation | No | Automatic at your marginal rate | | Salary Sacrifice | Gross salary reduced by the contribution | Yes — employer and employee | Automatic; most tax-efficient |

Relief at Source

Used by most personal pensions, SIPPs, and many workplace pensions. Your contribution is deducted from net pay (after tax). The pension provider automatically claims the basic-rate (20%) top-up from HMRC, regardless of your actual tax rate.

• If you are a basic-rate taxpayer: you get the full relief automatically.
• If you pay higher or additional rate tax: you need to claim the extra relief via Self Assessment or by contacting HMRC. You will receive this as either a tax refund or an adjustment to your PAYE tax code.

Net Pay Arrangement

Your pension contribution is deducted from your gross salary before income tax is calculated. You automatically receive relief at your marginal rate — no Self Assessment needed for higher-rate relief. NI is still calculated on gross salary (no NI saving).

Salary Sacrifice

The most tax-efficient method. You agree to reduce your gross salary by the pension contribution amount. Your employer pays the full gross contribution to your pension. Benefits:

• You save income tax at your marginal rate
• You and your employer save National Insurance on the sacrificed amount
• For a basic-rate taxpayer, the net cost of a £100 pension contribution is approximately £69 (versus £80 under RAS)

3. The annual allowance for 2026/27

The annual allowance is the maximum gross contribution across all your pension schemes (personal and workplace combined) that qualifies for tax relief:

| Allowance | 2026/27 amount | |---|---| | Annual Allowance (AA) | £60,000 | | Money Purchase Annual Allowance (MPAA) | £10,000 | | Tapered Annual Allowance (floor) | £10,000 |

The MPAA of £10,000 applies if you have flexibly accessed your defined contribution pension savings (e.g. taken a flexible drawdown income).

The Tapered Annual Allowance reduces the AA for very high earners. It applies if your threshold income (gross income minus personal pension contributions) exceeds £200,000 and your adjusted income (adding back employer contributions) exceeds £260,000. The taper reduces the AA by £1 for every £2 of adjusted income above £260,000, down to a minimum of £10,000.

4. Carry-forward of unused annual allowance

If you did not use your full annual allowance in recent years, you can carry forward the unused amounts to make a larger contribution this year:

| Tax year | Annual allowance | Carry-forward available if unused | |---|---|---| | 2023/24 | £60,000 | Yes | | 2024/25 | £60,000 | Yes | | 2025/26 | £60,000 | Yes | | 2026/27 (current) | £60,000 | — |

You must use the current year's allowance first, then draw on carried-forward amounts from the earliest year onwards. You must have been a member of a registered pension scheme in each year you wish to carry forward from.

5. Scottish pension tax relief — the nuances

Scotland sets its own income tax rates (SRIT), but pension providers operate under UK-wide HMRC rules for Relief at Source:

• Providers always claim 20% basic-rate relief from HMRC, regardless of the Scottish taxpayer's actual marginal rate
• Scottish starter-rate taxpayers (19%) therefore receive 1% over-relief — they get 20% but only paid 19% tax. HMRC does not reclaim this 1%
• Scottish intermediate (21%), higher (42%), advanced (45%), and top (48%) rate taxpayers can claim the difference above 20% via Self Assessment

| Scottish band | Rate | Relief via provider | Extra via SA | Net cost of £100 contribution | |---|---|---|---|---| | Starter | 19% | 20% | −1% (over-relief) | £81 | | Basic | 20% | 20% | 0% | £80 | | Intermediate | 21% | 20% | +1% | £79 | | Higher | 42% | 20% | +22% | £58 | | Advanced | 45% | 20% | +25% | £55 | | Top | 48% | 20% | +28% | £52 |

This makes pension contributions even more valuable for Scottish higher and advanced rate taxpayers than for their counterparts in England.

6. The Lifetime Allowance has been abolished

From 6 April 2024, the Lifetime Allowance (LTA) was removed. It has been replaced by:

• Lump Sum Allowance (LSA): £268,275 — maximum pension commencement lump sum you can take tax-free
• Lump Sum and Death Benefit Allowance (LSDBA): £1,073,100 — covers tax-free lump sums on death

These are limits on tax-free lump sums, not on the total value of your pension pot. There is no longer a ceiling on how much your pension pot can be worth.
