How long is a Gift Aid declaration valid?

Charities can claim Gift Aid on a single donation, donations made in the future and any donations made in the past four years. It’s valid until the donor is no longer a UK taxpayer. You must make sure that the donor’s information is accurate at the time your charity makes a Gift Aid claim, eg it’s useful to check if your donors have a new address.

It’s good practice to send new Gift Aid forms to your supporters to update your database and maximise your Gift Aid claim.
