Gift Aid Declarations Made Simple

Last updated: 2026-02-19

The missing piece of the puzzle

A Gift Aid declaration is a donor’s confirmation that they’re a UK taxpayer and want the charity to claim Gift Aid on their donations. Without it, HMRC won’t process the claim — no matter how complete the rest of your records are.

An estimated 40% of eligible donations lack a valid declaration. That’s not because donors would refuse if asked — it’s because nobody asked. The declaration form wasn’t available at the point of donation, or the online checkbox was buried below the fold, or the volunteer collecting cash at the door wasn’t trained to mention it.

The result is millions of pounds left on the table because of a missing piece of paper. Gift Aid Boost fixes that.

How our declaration emails work

When our system identifies donors with missing declarations, we send a branded email on your charity’s behalf. The process is straightforward:

  • Our system reviews your donor records and identifies those with eligible donations but no valid declaration on file
  • For each of these donors, we send a clear, professionally designed email from your charity
  • The email contains the full declaration wording and a single button to confirm
  • One click, and the declaration is recorded with a complete audit trail

You authorise the outreach before any emails are sent. We never contact your donors without your explicit approval.

What the donor sees

The email is designed to be clear, trustworthy, and quick to act on:

  • Your charity’s name is prominent throughout — this is your email, not ours
  • A brief explanation of what Gift Aid is and why it matters, in plain English
  • The full declaration wording, clearly visible and not hidden behind a link
  • One prominent button to confirm the declaration
  • An alternative link for donors who don’t pay enough UK income tax to cover the Gift Aid amount

The entire experience takes seconds, not minutes. There are no forms to fill in, nothing to print, nothing to sign, and nothing to post back. The donor reads, clicks, and it’s done.

Legally valid under UK law

You might wonder whether a single click can constitute a legally valid Gift Aid declaration. It can, and here’s why:

  • Electronic Communications Act 2000: UK law explicitly recognises electronic communications as valid for legal purposes, including tax declarations
  • HMRC guidance: HMRC expressly accepts electronic Gift Aid declarations, including those made via email confirmation
  • Charity Tax Group confirmation: The UK’s leading authority on charity taxation confirms that no physical signature is required for a Gift Aid declaration
  • Established contract law: One-click acceptance has been enforceable under English law since L’Estrange v Graucob [1934] — a party is bound by terms they had the opportunity to read, whether or not they actually read them

Our declaration emails are designed with this legal framework in mind. The full declaration wording is displayed prominently before the confirmation button, ensuring the donor has every opportunity to read it.

Full audit trail

Every declaration is logged with a complete record of when it was sent, when it was confirmed, and the exact wording that was displayed. This audit trail is your proof of a valid declaration if HMRC ever queries a claim.

We store declaration records for 6 years, matching HMRC’s audit window, so the evidence is there whenever you need it.

Gentle reminders, never spam

If a donor doesn’t respond, we send a small number of gentle reminders at sensible intervals before the request quietly expires. The tone is always respectful and low-pressure.

Your donor relationships matter more than any individual declaration, and our process reflects that. We’ll never bombard your supporters with emails.

What about donors who can’t declare?

Some donors don’t pay enough UK income tax to cover the Gift Aid amount on their donations. If a charity claims Gift Aid on their behalf, the donor could be liable to HMRC for the difference — which is obviously not the outcome anyone wants.

Our emails include a clear, dignified option for these donors to let us know. They click an alternative link, and they won’t be asked again for that tax year. No awkward conversations, no guilt — just a simple acknowledgement that not every donor can declare, and that’s perfectly fine.
