How does 40% tax relief work on a SIPP?

When you contribute to a SIPP, the provider claims 20% basic rate tax relief automatically (adding £25 for every £80 you put in, so your £80 becomes £100 in the pension). As a higher rate taxpayer, you claim the extra 20% back through your Self Assessment tax return — effectively getting £40 of relief for every £60 you contribute net (£100 gross).

What is the annual allowance for a SIPP in 2026/27?

The annual allowance is £60,000 for 2026/27, or 100% of your UK earnings — whichever is lower. If you haven't fully used your allowance in the last 3 tax years, you may be able to 'carry forward' unused allowance and contribute more than £60,000 in a single year.

Should a higher rate taxpayer use a SIPP or ISA?

Both serve different purposes. A SIPP gives 40% tax relief now but tax is due on withdrawals in retirement (at your then-marginal rate). An ISA gives no upfront relief but withdrawals are tax-free. For most higher rate taxpayers, a SIPP is more efficient because they get 40% relief now and will likely pay only 20% tax on withdrawals (as a basic rate pensioner). Consider both.

Can I contribute to a SIPP and still have a workplace pension?

Yes. You can contribute to both a SIPP and a workplace pension simultaneously. The total contributions across all pensions in a year must not exceed the £60,000 annual allowance (or your earnings, if lower). Employer contributions also count toward this limit.

Best SIPP for Higher-Rate Taxpayers UK 2026/27 — Claim 40% Tax Relief

    The higher-rate SIPP advantage in one number: 40p for every £60 you invest
    A higher rate taxpayer who contributes £60 net to a SIPP gets £80 in the pension (basic 20% relief added automatically), then claims another £20 back through Self Assessment — a net cost of £60 for £100 in the pension. That's a 66.7% instant return before any investment growth.
  

If you pay 40% income tax, a SIPP is one of the most efficient ways to build wealth available in the UK. This guide covers how the tax relief works, how to claim the extra 20%, and which SIPP platform best suits a higher earner's needs.

How 40% tax relief works — step by step

Step	What happens	Basic rate (20%)	Higher rate (40%)
You pay in	Net contribution from your bank	£800	£800
Provider claims	20% basic rate relief added automatically	+£200	+£200
In the pension	Gross contribution	£1,000	£1,000
You claim via SA	Extra 20% relief through Self Assessment	—	+£200 refund
Net cost to you	Actual money out of pocket	£800	£600
Effective relief	—	20%	40%

Claiming the extra 20%: The additional 20% relief is NOT automatic. You must claim it through your Self Assessment tax return. HMRC will either refund you directly or adjust your tax code. If you don't file Self Assessment, call HMRC or ask your accountant to claim on your behalf.

Annual allowance & carry forward

The annual pension allowance for 2026/27 is £60,000 (or 100% of UK earnings, whichever is lower). All contributions from you and your employer count toward this limit.

Carry forward: If you haven't used your full annual allowance in the last 3 tax years, you can carry forward unused allowance and contribute more than £60,000 in a single year. Higher earners who have recently entered the 40% band often have unused carry-forward from earlier lower-income years — making large one-off contributions extremely efficient.

Frequently asked questions

When you contribute to a SIPP, the provider claims 20% basic rate tax relief automatically — so your £800 contribution becomes £1,000 in the pension. As a higher rate taxpayer, you claim the additional 20% back through your Self Assessment tax return, getting a £200 refund. Your net cost for £1,000 in the pension is £600 — 40% effective relief.

The annual allowance is £60,000 for 2026/27, or 100% of your UK earnings — whichever is lower. This covers contributions from you and your employer combined. If you haven't used your full allowance in the last 3 tax years, you can carry forward unused allowance to contribute more in a single year.

Both serve different purposes. A SIPP gives 40% tax relief now but withdrawals in retirement are taxable (at your then-marginal rate, typically 20% for a basic rate pensioner). An ISA gives no upfront relief but withdrawals are always tax-free. For most higher rate taxpayers, maximising SIPP first then using an ISA for flexibility is the optimal approach.

Yes. You can have both a SIPP and a workplace pension simultaneously. Total contributions to all pensions in a year must not exceed the £60,000 annual allowance (including employer contributions). A SIPP is especially useful if your workplace pension has limited fund choice or high charges.
