SIPP Tax Relief & Regional Tax Savings Calculator (2026/27)
Calculate pension tax relief for UK taxpayers, including Scottish income tax bands (Starter, Basic, Intermediate, Higher, Advanced, Top).
📊 SIPP Tax Relief Breakdown
Under the UK tax system, pension contributions trigger valuable tax relief that reduces the effective out-of-pocket cost of saving for retirement. While basic rate relief of 20% is claimed at source by the pension provider for all UK taxpayers, taxpayers in higher income tax brackets are eligible to reclaim additional tax relief directly from HMRC.
Because income tax rates are devolved in Scotland, Scottish taxpayers paying the Intermediate (21%), Higher (42%), Advanced (45%), or Top (48%) rates receive enhanced tax relief compared to taxpayers in England, Wales, or Northern Ireland.

📑 Common Pitfalls
- Assuming Provider Claims Full Higher Rate Relief: SIPP platforms only claim 20%. You must contact HMRC or complete a Self Assessment tax return to receive your 22% (Scotland) or 20% (rUK) higher rate tax refund.
- Forgetting Salary Sacrifices: If contributing via employer salary sacrifice, tax relief is given automatically via payroll (saving NI as well), so manual SIPP tax reclaims are unnecessary.
- Tapered Personal Allowance Trap: Earnings between £100,000 and £125,140 face an effective 60% (rUK) or 67.5% (Scotland) marginal tax rate due to losing £1 of Personal Allowance for every £2 earned above £100k; SIPP contributions effectively restore the Personal Allowance!
❓ Frequently Asked Questions (FAQ)
Scottish taxpayers who pay the Intermediate (21%), Higher (42%), Advanced (45%), or Top (48%) rates receive 20% automatically in their SIPP pot from the pension provider. They can claim the remaining 1%, 22%, 25%, or 28% relief by completing an annual Self Assessment tax return or by contacting HMRC to update their PAYE tax code.
Income between £100,000 and £125,140 loses the £12,570 Personal Allowance at a rate of £1 for every £2 of income. Making a gross SIPP contribution reduces your Adjusted Net Income. Bringing your adjusted income back down to £100,000 restores your full Personal Allowance, resulting in an effective tax relief rate of up to 60% (rUK) or 67.5% (Scotland).
Under Relief at Source rules, HMRC allows SIPP providers to add a full 20% basic rate tax relief to pension contributions made by Scottish starter rate (19%) taxpayers, without HMRC reclaiming the 1% difference. This gives starter rate taxpayers an advantageous relief boost.
Direct personal SIPP contributions reduce Income Tax but do not reduce National Insurance (NI) contributions. However, if your employer operates a Salary Sacrifice pension arrangement, both Income Tax and employee/employer National Insurance contributions are saved automatically through payroll.
