HMRC-compliant declarations, one-click export, zero manual entry.
When a UK taxpayer donates to a charity and signs a Gift Aid declaration, the charity can claim 25p for every £1 from HMRC. This is because the donor has already paid 20% income tax on the money — the charity is simply reclaiming that tax. A £100 donation becomes £125 for the charity at no extra cost to the donor.
If you pay tax at 40% or 45%, you can claim the difference between your rate and the basic rate (20%) through your Self Assessment tax return. On a £100 donation: the charity claims £25 Gift Aid, and you claim back £25 (at 40%) or £31.25 (at 45%) on your tax return.
HMRC requires a specific declaration from the donor confirming they are a UK taxpayer. The charity must keep records of: the donor's full name, home address, the declaration date, and the amount(s) donated. Generate a compliant Gift Aid declaration →
Most charities lose Gift Aid because they don't capture declarations properly. PledgeNow captures Gift Aid on every pledge automatically — HMRC model wording, timestamped consent, and one-click HMRC export. No manual data entry, no missing fields.
Gift Aid is a UK tax relief scheme that allows charities to reclaim 25p for every £1 donated by a UK taxpayer. The donor must have paid at least as much income or capital gains tax as the charity will reclaim. It costs the donor nothing extra — the charity simply claims the tax back from HMRC.
Any UK taxpayer who has paid income tax or capital gains tax at least equal to the Gift Aid claimed on their donations in that tax year. If you pay the basic rate of 20%, your £10 donation lets the charity claim £2.50 from HMRC. Non-taxpayers should not sign a Gift Aid declaration.
Yes. If you pay 40% tax, you can claim back 20% of your gross donation (the donation + Gift Aid) through your Self Assessment tax return. On a £100 donation, the charity gets £125 (via Gift Aid), and you can claim back £25 on your tax return — making the true cost to you just £75.
Yes, Gift Aid applies to every donation — one-off, monthly, weekly, or annual. The charity needs one Gift Aid declaration from you, and it covers all past donations (up to 4 years) and future donations until you cancel it.
If the Gift Aid claimed on your donations exceeds the tax you've paid, you'll owe HMRC the difference. For example, if you donate £1,000 and the charity claims £250 Gift Aid, but you've only paid £200 in tax, you'd owe HMRC £50. Always check your tax liability before signing a Gift Aid declaration.
PledgeNow captures Gift Aid declarations automatically when donors pledge. Every pledge includes HMRC-compliant model wording with timestamped consent. Charities can export a one-click CSV ready for HMRC submission — every field, every time.
