The Power of UK Pension Tax Relief
Pensions are one of the most tax-efficient wealth vehicles available to UK residents. Contributions receive income tax relief at your highest marginal rate: 20% basic rate relief is added automatically into your pot, while 40% higher rate and 45% additional rate taxpayers can claim an extra 20% or 25% refund through HMRC Self Assessment.
Under the standard Annual Allowance, you can contribute up to £60,000 per tax year (or 100% of relevant earnings) into pensions with full tax relief.
Accessing Your Pension: The 25% Tax-Free Lump Sum
Under UK pension freedoms, once you reach minimum retirement age (age 55, rising to 57 in April 2028), you can withdraw up to 25% of your total accumulated pension pot completely free from income tax, subject to the statutory Lump Sum Allowance limit of £268,275.
The remaining 75% can be left invested for flexible drawdown or used to purchase a guaranteed lifetime annuity.
