Pensions / withdrawal planning

Pension drawdown tax calculator

Use this when the real question is not "can I take money out?" but "how much of this withdrawal is tax-free, how much lands in my taxable income, and what is the likely net amount after HMRC takes its slice?"

Scope: this is a first-pass 2026/27 planning tool for UK private pension withdrawals using rest-of-UK income tax bands. It assumes authorised withdrawals and does not model provider emergency PAYE month-one codes, Scottish rates, Marriage Allowance, or protected tax-free cash.

What this means

This tool separates tax-free cash from the taxable element, then stacks the taxable slice on top of your other income for the year.

Professional read

Key assumption

The tool uses rest-of-UK 2026/27 income tax rates and assumes the withdrawal is authorised and taxed in the year you take it.

Common mistake

Comparing the gross pension withdrawal with your bank receipt and forgetting that only the tax-free slice is untouched by income tax.

Best next action

If the taxable slice tips you into higher-rate tax, test smaller staged withdrawals or compare the year-end result with other income already expected.

When it breaks down

Scottish taxpayers, protected tax-free cash, emergency PAYE month-one codes, and DB/annuity cases need a more tailored review than this first-pass tool.

Methodology and source basis

Built around HMRC 2026/27 PAYE thresholds and GOV.UK pension-withdrawal guidance. It uses the standard Personal Allowance, the 25% tax-free cash rule where available, and the 20% / 40% / 45% rest-of-UK income tax bands.
