What official pages say about the threshold
GOV.UK’s Winter Fuel Payment income page says that if your total income is over £35,000, HMRC will take your Winter Fuel Payment back. Your partner’s income does not count towards your total. The same individual-income rule is restated on mygov.scot for Pension Age Winter Heating Payment. The official charge guidance, published on 26 November 2025, describes a new charge equal to the full value of a Winter Fuel Payment or Pension Age Winter Heating Payment received by pensioners with total income over £35,000. It also says the measure of income is the individual’s total income, as defined in section 23 of the Income Tax Act 2007, and that HMRC provides a dedicated checker.
That is why this calculator has no taper slider. A figure of £35,000 is not over the threshold on the wording GOV.UK uses (“over £35,000”). A figure of £35,000.01 is treated as over, and the estimated charge equals the payment you entered. If later official guidance publishes a different edge case or a taper, the official page wins and this tool should be updated. Enter the total amount of income you expect to receive in the tax year before any deductions, which is the instruction on the official income page, then confirm with the HMRC checker rather than treating this sketch as a tax bill.
How HMRC collects the charge, and who is exempt
GOV.UK says HMRC will usually collect the amount through your tax code, and will contact you by email or post if the code changes. If you complete a Self Assessment tax return, you pay the charge through your tax bill instead and must include the winter payment on the return each year you get it. Online returns are usually pre-populated with a “Winter Fuel Payment charge” line. People who use Making Tax Digital for Income Tax are told they cannot pay the charge inside that software submission and should wait for HMRC to write with how and when to pay. The charge guidance also says people who received Income Support, income-based Jobseeker’s Allowance, Pension Credit, income-related Employment and Support Allowance or Universal Credit in the qualifying week will not be liable to the charge, regardless of their income. Tick that box if it applies; the estimate then shows no clawback.
The official Winter Fuel Payment opt-out page, checked on 13 November 2026, says you can no longer opt out for 2026 to 2027. You will be able to opt out for 2027 to 2028 from 21 December 2026. If you already opted out and want to opt in again for this winter, contact the Winter Fuel Payment Centre before 31 March 2027. Social Security Scotland still describes an opt-out and an award-cancellation route for Pension Age Winter Heating Payment; if you opt out after a decision, you still get this winter’s payment unless you cancel the award and return it. For how the underlying payment is figured, use the Winter Fuel Payment calculator or the income-over-£35,000 guide. If you file Self Assessment, AssessTally is a sister site with educational UK tax estimators — it does not compute this winter-payment charge.
