Frequently Asked Questions
Clear answers regarding UK pension tax relief, the £60,000 Annual Allowance, and high-earner tapering.
How do I claim higher rate (40%) and additional rate (45%) pension tax relief? ▼
If you contribute to a personal pension or SIPP under 'Relief at Source', your provider automatically claims 20% basic rate relief and adds it to your pot. To claim the remaining 20% (higher rate) or 25% (additional rate), you must declare your gross pension contributions on your HMRC Self-Assessment tax return, or call HMRC to adjust your PAYE tax code.
How does the 3-year carry forward rule work? ▼
Carry forward allows you to utilize unused Annual Allowance from the 3 previous tax years, provided you were a member of a registered pension scheme in those years. You must use your current year's £60,000 allowance first, then tap the oldest unused year (e.g. 2021/22) first. Your personal contributions remain capped at 100% of your current tax year relevant earnings.
What is Salary Sacrifice and why is it superior for pensions? ▼
Under a salary sacrifice arrangement, you contractually agree to reduce your salary in exchange for your employer making the equivalent contribution directly into your pension. Because your salary is lower, you pay less income tax AND you save on National Insurance contributions (up to 8% or 2%). Many generous employers also pass on their 13.8% employer NI savings into your pension pot!
What happened to the Lifetime Allowance (LTA)? ▼
The Lifetime Allowance was formally abolished on 6 April 2024. It was replaced by two new limits: the Lump Sum Allowance (LSA) of £268,275, which caps the maximum tax-free 25% cash lump sum you can take during your life, and the Lump Sum and Death Benefit Allowance (LSDBA) of £1,073,100, which limits tax-free lump sums on death.
