Without a valid declaration, you cannot reclaim tax on a donation, no matter how generous the gift. When a UK taxpayer signs, they confirm they have paid enough tax to cover the Gift Aid claimed and agree that your charity or CASC may reclaim that tax. If they have not paid enough tax, they may need to pay the difference to HMRC.
Minimum information
HMRC expects declarations to include:
- The donor's full name.
- Home address, including postcode.
- The date of the declaration.
- A clear statement that the donor is a UK taxpayer and wants Gift Aid applied.
- Identification of your charity or CASC (name and ideally charity reference).
Use HMRC's model wording where possible. Custom wording is allowed if it meets the legal tests, but model text reduces rejection risk.
One-off versus ongoing
An ongoing declaration can cover all future donations until the donor cancels. That is ideal for monthly subscriptions or standing orders. One-off declarations can cover a single gift or a specific campaign. Make sure the form matches how the person actually gives.
Paper and digital
Paper forms signed by hand remain common at AGMs and registration days. Digital declarations are valid if you can show the donor's identity and consent — for example a tick box plus name, address, and an audit trail on your website or membership portal. Store PDF scans or system exports securely. See how Vasker protects donor data if you collect declarations online.
When people join online, capture the tick box before payment completes. Store a timestamp, IP audit if available, and the exact wording shown. Screenshots of old join forms are weaker evidence than system logs.
Linking declarations to donations
Every claimed donation must be tied to a declaration in force at the time of the gift. Your records should answer: who gave, how much, when, and which declaration covers it.
When you cannot claim
- No declaration on file.
- Incomplete address or missing date.
- The payment is not a gift (goods, services, or excessive benefit).
- The donor is not a UK taxpayer or has not paid enough tax.
- Company donations — companies use different rules; individuals use Gift Aid.
Cancellations, renewals, and names
Donors can cancel at any time. Stop claiming on gifts after the cancellation date. If they move house, update the address. If they marry and change name, obtain an updated declaration or clear evidence linking old and new records.
Each year, confirm standing declarations still cover new payment amounts. If someone increases their regular gift significantly, consider whether a fresh declaration is prudent even if the old one technically still applies.
Where a parent gives on behalf of a household, the taxpayer who pays tax signs. Junior members do not sign declarations themselves. For joint gifts, HMRC expects clarity on who is the taxpayer donor.
Retention and storage
Keep declarations and donation records for at least six years from the end of the accounting period. See the record-keeping guide.
Declarations contain personal data. Store them securely, share only with those who need them for claims, and explain retention in your privacy notice. See security and compliance.
Paper belongs in a fire-resistant cabinet or scanned promptly. Digital files need access controls, not a shared USB stick. Label batches by join year. If you merge with another club, merge declaration files and deduplicate before the next claim. Duplicate claims on the same gift create compliance risk.
Collection checklist
- Ask at the point of joining, not months later.
- Train event volunteers not to put cash in the tin without offering a form for larger gifts.
- Reconcile standing orders monthly so new payers without declarations are flagged quickly.
- Run a declaration drive before your annual claim.
- Once a year, compare active payers to declaration holders. Remove duplicates, update addresses, and chase gaps.
Small anonymous cash may still qualify under the Gift Aid Small Donations Scheme (GASDS) — a top-up on small cash gifts without named declarations within limits. That does not replace declarations for named gifts.
If a rule feels unclear
Rules and thresholds change. Check current HMRC and Charity Commission guidance for your organisation before you claim or file. This is general information, not tax or legal advice.
If something is unclear, pause that claim line rather than guessing. HMRC penalties for careless claims cost more than waiting for advice. Local charity accountants, CVS treasurer networks, and national membership bodies often answer simple questions cheaply or free.
Involve another volunteer in spot checks. A second pair of eyes on a claim spreadsheet or declaration file catches errors you have stared at too long. Committees should treat that time as governance, not optional extra work.
