How does Gift Aid work and what tax reclaim can charities and donors get in 2026?

Full answer

Gift Aid is the UK's system for charities to recover the income tax that donors have already paid on the money they give. It allows the government's income tax to flow to the charity rather than to the Treasury, without any additional cost to the donor. How Gift Aid works for the charity When a UK taxpayer signs a Gift Aid declaration and makes a donation, they are confirming they have paid (or will pay) enough UK income or capital gains tax to cover the basic-rate tax on the gross gift. The charity then claims 25p from HMRC for every GBP 1 donated. Gross up: a GBP 100 cash donation is treated as GBP 125 gross (GBP 100 is 80% net of 20% basic rate tax). The charity reclaims GBP 25, making the total charity receipt GBP 125. The donor's cost remains GBP 100. Higher-rate taxpayer relief Higher-rate taxpayers (40%) receive additional personal relief equal to the difference between their marginal rate and the basic rate (20%): 20% of the gross gift. This is claimed via Self Assessment. Example: GBP 1,000 cash donation -- Gross gift: GBP 1,250 -- Charity receives: GBP 1,250 (after reclaiming GBP 250 from HMRC) -- Basic-rate taxpayer: total personal cost GBP 1,000 -- Higher-rate taxpayer: reclaims 20% x GBP 1,250 = GBP 250; net personal cost GBP 750 -- Additional-rate taxpayer (45%): reclaims 25% x GBP 1,250 = GBP 312.50; net personal cost GBP 687.50 Backdating A Gift Aid declaration for a donation in the current or immediately prior tax year can be backdated -- useful for self-assessment taxpayers who make a large donation early in the new tax year but want relief in the prior year. ANI reduction Gift Aid donations also reduce Adjusted Net Income (ANI), which can restore the personal allowance if ANI is near GBP 100,000, reduce HICBC, and help avoid the 60% effective rate trap. Conditions -- Donor must be a UK taxpayer -- Tax covered must equal the basic-rate tax reclaimed by the charity: if donations exceed 4x the taxpayer's total income and CGT tax liability, the shortfall must be paid to HMRC -- Gift Aid cannot be claimed on donations where the donor receives a "benefit" exceeding the lower of GBP 250 or 25% of the donation (small tokens excluded)
