What will HMRC look at if it audits our Gift Aid?

England and Wales: This page sets out the position in full. Scotland: the same position, with no difference in principle — taxation, and HMRC’s audit powers over it, are reserved throughout the UK. Northern Ireland: the same position, with no difference in principle, for the same reason.

Does HMRC require a written Gift Aid declaration?

No. HMRC requires a valid declaration, and a valid declaration may be oral, given in person or by telephone. The same holds in a Gift Aid audit in England and Wales, Scotland and Northern Ireland. It is the first thing the treasurer or trustee preparing the file needs to get right.

The page assumes the charity is already claiming Gift Aid. An audit looks back at those claims.

This is the single most consequential correction to what most checklists say. It agrees with what Gift Aid records you have to keep: HMRC does not require a written declaration. Chapter 7 requires an appropriate declaration, and Chapter 3 expressly permits an oral one.

A charity that keeps only written declarations is enforcing a rule that does not exist. If it rejects a valid oral declaration, it may be under-claiming as a result.

An oral declaration is not effective on its own (the page on what a Gift Aid declaration has to say sets out the whole rule). It only becomes usable once the charity sends the donor a written record of it. The charity cannot reclaim tax on that donation until it has done so. The donor then has a fixed window, from being sent that record, in which to cancel — with retrospective effect.

What an audit tests, either way, is whether a valid declaration exists behind the claim. Not whether it happened to be written down at the moment it was given.

What does HMRC check in a Gift Aid audit?

A Gift Aid audit is HMRC’s check that a charity’s repayment claims are supported by its records. HMRC’s own guidance sets out two sets of records it examines together. First: records supporting a tax repayment claim — donation records, declarations, and banking and cash records. Second, and separately: the charity’s own accounting records, systems and procedures — the financial controls the money hub covers.

HMRC’s auditor also checks that each gift meets the conditions in the legislation and that donor benefits stay within the statutory limits. It checks, too, that the repayment was received and banked into the right account.

A schedule of donations that cannot be traced back into the underlying accounts is no better evidenced than one with no records at all.

The review period follows the same company/trust divide that runs through the claim time limit and the retention rules. A charitable trust is reviewed by tax year. A charitable company is reviewed by accounting period ended. Knowing which applies to your charity tells you which year HMRC’s questions will be framed around.

The three mandatory requirements behind every claim

Three requirements sit behind every line of a claim. All three are legal requirements, not good practice:

1. A valid declaration for the donor, on the terms above.
2. An audit trail linking each donation to an identifiable donor holding that declaration. HMRC is explicit: transcribing declarations into a database does not, by itself, satisfy this. The underlying record has to survive, not just a summary of it.
3. Evidence that the donor was given an adequate explanation of their own tax position. That includes their responsibility to pay any shortfall if they have not paid enough tax to cover the relief claimed. The charity must be able to demonstrate that it gave this explanation. Asserting that it did is not enough.

A charity’s enduring declarations — the ones covering donations that continue over time — have to be kept for as long as the donations continue. The retention clock only starts once they stop. That is materially longer than the fixed periods most people assume apply to everything. It is a common gap in an otherwise tidy file.

What commonly goes wrong in a Gift Aid audit

Four things are commonly repeated as HMRC’s list of typical audit failures, and three of the four are wrong as usually stated. The source verification behind this page corrected them against Chapter 7 and Chapter 3, read in full.

• “No written declaration” is corrected above. The failure is no valid declaration, not no written one.
• “HMRC requires a full name, not an initial” is deleted outright. HMRC’s own guidance says a full name is only recommended. Its own model declaration form offers “first name or initial(s)” as an option. Its guidance on what a declaration must contain positively contemplates an initial and surname. An initial is not automatically fatal to a declaration.
• Claims on non-qualifying receipts belong to a different chapter of HMRC’s guidance entirely. Event tickets, raffles, and lottery tickets are a real way a claim can fail — see which of your income can carry Gift Aid. They are not something Chapter 7 itself discusses. Attributing them to the audit chapter overstates what that chapter covers.
• Weak record-keeping is real, and HMRC states it sharply. Take a pool of cash collected without attributing it to anyone in particular. It cannot be arbitrarily allocated afterwards to whichever donors happen to have a declaration on file, and claimed on that basis.

No published HMRC list is headed “common failures”. The four-item version in wide circulation is a construction, not a quotation. The version above corrects it against the primary text, rather than repeating the construction uncorrected.

What is HMRC’s Gift Aid “yellow card”?

The yellow card is an arrangement agreed by both HMRC and the charity. Under it, HMRC recovers only the tax due for the year under review while the charity improves its record-keeping. It is real, but it is not a leniency HMRC extends at its own discretion.

HMRC agrees to recover only the tax due for the year under review. The charity agrees to take the remedial action HMRC considers necessary.

If agreement cannot be reached, HMRC recovers tax for the year under review and earlier years, based on the error rate found. If the charity does not follow through on the agreed remediation, the next examination goes back and recovers any earlier years still in date. HMRC says that follow-up is not usually more than three years after the first review, and may be sooner.

Whether a card is offered at all depends on two things in HMRC’s published table. One is the error rate after repair; the other is the amount of tax at stake.

Separately, HMRC operates a de minimis limit. It will treat a charity as not penalised for errors in its claims where two things are true. The error rate is low, calculated after the charity has had the chance to correct its own sample. And the charity claims under a modest amount of Gift Aid per year.

The precise supporting figures, beyond the headline error rate and claim-level thresholds, sit in HMRC’s own published table.

Not all of them have been independently pinned to a fact record in this project yet. Flagged for a future update, rather than typed here without a source.

What is still unknown about HMRC’s audit powers?

The legal mechanism behind an HMRC information request in a Gift Aid audit is still not established; the look-back period is now closed. Two different things sat under this heading before the 19 August verification, and only one is resolved.

Closed. HMRC will not usually recover tax for more than a fixed number of years before the year under review. That period can be extended in some circumstances. The charity’s own window to make a fresh claim for a year already reviewed runs on the same length.

Still open — and it is not an oversight in this page’s research. HMRC’s own audit-process guidance names no statutory provision anywhere. No Act, section or paragraph is given. It describes no formal enquiry procedure and no information-gathering power specific to a Gift Aid audit.

What legal mechanism underlies an HMRC information request in this context is not established from this source. This page does not guess at it.

That closes the Gift Aid part of the hub. The next step, assessing your corporation tax position, turns to trading income.

Common mistake: assuming the declarations alone will satisfy an audit

The declaration is the document everyone knows about, so it is natural to assume a complete folder of them is the whole job. It is not. Three things are required: a valid declaration, an audit trail linking each donation to an identifiable donor, and evidence the tax explanation was given. A perfect file of declarations with no audit trail and no evidence of the explanation fails on two of the three.

Worked example

Saltmarsh Trust, a charitable company, reviews its own Gift Aid file before any audit is notified. Because it is a company, HMRC would review it by accounting period, not tax year. So the self-review runs against the accounting period too.

The treasurer pulls a sample of donations and tests each one end to end. The test covers the ledger entry, the donor, the declaration behind it, and any evidence that the donor was told about their own tax position.

Where the trail runs cleanly from ledger to declaration to evidence, the sample passes. Where it does not, the gap gets fixed while it still can be — not discovered for the first time when HMRC asks. Typical gaps are a declaration that cannot be matched to a specific gift, or no record that the tax explanation was ever given.
