The charity uplift and tax-cover screen use eligible individual cash donations. A valid declaration is required, and your annual Income Tax and Capital Gains Tax must cover the tax reclaimed across all Gift Aid donations.
For declaration, claim and record-keeping rules, read the Gift Aid and Charitable Donations guide for 2026/27.
It applies the selected marginal Income Tax rate only to the donation amount assigned to that band. It does not calculate your full tax return, Personal Allowance taper, High Income Child Benefit Charge, other reliefs or donation eligibility.
Payroll Giving, company gifts, non-cash gifts and donations with benefits are outside this estimate.
The charity uplift, donor tax-cover condition and additional-relief route follow HMRC and GOV.UK guidance. Confirm your own total tax and donation eligibility before making a declaration.
