If you are a higher rate or additional rate taxpayer, you are eligible to claim relief on the difference between the basic rate and your highest rate of tax. The charity you donate to can reclaim the basic rate of tax from donations made by taxpayers.

For example:

If you donated £5,000 to charity, the total value of the donation to the charity is £6,250. You can claim additional tax back of:

• £1,250 if you pay tax at the higher rate of 40% (£6,250 × 20%),
• £1,562.50 if you pay tax at the additional rate of 45% (£6,250 × 20%) plus (£6,250 × 5%).

If you are a higher rate or additional rate taxpayer you have the option to carry back your charitable donations to the previous tax year. A request to carry back the donation must be made before or at the same time as your previous year’s Self-Assessment return is completed.

This means that if you made a gift to charity in the current 2021-22 tax year that ends on 5 April 2022, you can accelerate repayment of any tax associated with your charitable giving. This can be a useful strategy to maximise tax relief if you will not pay higher rate tax in the current tax year but did in the previous tax year.

You can only claim if your donations qualify for gift aid. This means that your donations from both tax years together must not be more than 4 times what you paid in tax in the previous year. If you do not complete a tax return you need to use a P810 form to make a claim.
