I want to Gift Aid my donation and any donations I make in the future or have made since February 15th 2020 to A Call to Action. I am a UK tax payer and understand that if I pay less income tax and/or capital gains tax than the amount of Gift Aid claimed on all my donations in that tax year it is my responsibility to pay any difference.
(Note that if you pay Income Tax at the higher or additional rate and want to receive the additional tax relief due to you, you must include all your gift aid donations on your Self-Assessment tax return or ask HM Revenue and Customs to adjust your tax code.)
