Donating through Gift Aid means charities can claim an extra 25p for every £1 you give. It will not cost you any extra.
You need to make a Gift Aid declaration for the charity to claim. You usually do this by filling in a form. Your donations will qualify as long as they’re not more than 4 times what you have paid in tax in that tax year (6 April to 5 April).
If you pay 40% tax you can claim the difference between your tax rate and gift aid. Say you donate £100 to us - we claim Gift Aid to make your donation £125. You pay 40% tax so you can personally claim back £25.00 (£125 x 20%).
