What is Gift Aid Carry-Back?
An election allowing a Gift Aid donation made after the end of a tax year, but before the Self Assessment filing deadline, to be treated as if made in the previous tax year, typically to obtain higher-rate tax relief sooner or use up available relief.
Full Definition
Gift Aid carry-back is an election available to individual taxpayers who complete a Self Assessment return, allowing a donation made in the current tax year to be treated, for tax relief purposes, as if it had been made in the previous tax year instead. The election must be made before or at the same time as filing the Self Assessment return for the earlier year, and only donations made between the end of that earlier tax year and the date the return is actually filed (or, at the latest, the 31 January filing deadline) can be carried back -- a donation cannot be carried back once the return for the earlier year has already been submitted without the election. The main reason higher and additional-rate taxpayers use carry-back is to bring forward the additional tax relief they are entitled to claim personally. When a UK taxpayer gives to charity under Gift Aid, the charity reclaims basic-rate tax (effectively grossing up the donation by 25%), and higher-rate (40%) or additional-rate (45%) taxpayers can then claim the difference between their marginal rate and the basic rate through their Self Assessment return, either as a refund or a reduction in their tax bill. Carrying a donation back to the previous year means this additional relief is calculated using the previous year's income and tax rates, which can be advantageous if the taxpayer had significantly higher income, or was pushed into a higher tax bracket, in the earlier year rather than the current one. Carry-back can also be useful for someone whose income in the current year has dropped below a threshold where they would otherwise get less benefit from the relief -- for example, someone who has retired partway through the year and had substantially higher income in the previous year. The election is made by ticking the relevant box on the Self Assessment return (or via a formal election in a letter to HMRC) and specifying the amount to be carried back; it cannot be partially reversed once the earlier year's return has been finalised, so taxpayers should check their numbers carefully, ideally with a tax adviser, before submitting the election.
