How is a £500,000 pension pot taxed if I take income drawdown?

From a £500,000 pension pot, you can normally take £125,000 (25%) as a tax-free lump sum, leaving £375,000 to draw down as taxable income. Withdrawals from the taxable portion are added to your other income for the tax year and taxed at your marginal rate.

Full answer

A £500,000 defined contribution pension pot accessed through flexi-access drawdown from normal minimum pension age (currently 55, rising to 57 from April 2028) allows a Pension Commencement Lump Sum of up to 25% tax-free -- £125,000 -- leaving £375,000 in the taxable portion. Every withdrawal from that £375,000 is added to any other income you have in the tax year it is taken and taxed at your marginal Income Tax rate. With a pot this size, careful sequencing matters a great deal: spreading withdrawals over twenty-five or more years of retirement, using the Personal Allowance and basic-rate band each year alongside the State Pension, can keep a substantial share of the £375,000 taxed at 0% to 20%, while any single tax year drawing much more than around £37,700 to £50,270 of taxable pension income (combined with other income) will see the excess taxed at 40%, and combined income above £100,000 in a given year will also start tapering the Personal Allowance. Many people with a pot this size use a mix of drawdown and a small annuity, or phase retirement over several years, to manage the tax impact. Pension providers usually apply an emergency tax code to the first withdrawal in a tax year, correctable via HMRC or automatic year-end reconciliation.
