Gift Aid for Higher Rate Taxpayers: Claim Extra Relief

The Accounted Tax Team·5 February 2026·7 min read

Gift Aid is one of the most well-known tax reliefs in the UK, but many higher rate taxpayers do not realise they are entitled to claim additional relief beyond what the charity receives. If you pay tax at 40% or 45%, you are leaving money on the table if you do not claim this relief on your Self Assessment return.

This guide explains exactly how Gift Aid works for higher and additional rate taxpayers, with worked examples at both 40% and 45%, plus the common mistakes to avoid.

How Gift Aid Works: The Basics

When you make a donation to a UK-registered charity and tick the Gift Aid box, the charity can reclaim basic rate tax from HMRC. This is worth 25p for every £1 you donate.

This happens because your donation is treated as having been made after basic rate tax (20%) has been deducted. The charity claims back the tax that was "already paid" on your donation.

So if you donate £100, the charity reclaims £25 from HMRC, making your donation worth £125 to the charity. That £125 figure is the gross donation — the amount before basic rate tax was deducted.

The maths works like this:

You donate £100 (the net amount)
Gross donation = £100 / 0.80 = £125
Basic rate tax reclaimed by charity = £125 x 20% = £25
Total received by charity = £100 + £25 = £125

This basic rate relief applies to all taxpayers who have paid enough UK tax to cover it. But for higher and additional rate taxpayers, there is more relief to claim.

Extra Relief for Higher Rate Taxpayers (40%)

If your income exceeds £50,270 in the 2025/26 tax year, you pay tax at 40% on income above that threshold. When you make Gift Aid donations, you can claim the difference between the higher rate (40%) and the basic rate (20%) through your Self Assessment return.

How the Relief Works

The gross donation amount extends your basic rate band. This means income that would have been taxed at 40% is instead taxed at 20%, giving you relief at the difference of 20%.

Worked Example: 40% Taxpayer

Sarah is a self-employed consultant with taxable income of £70,000 in 2025/26. She donates £1,000 to charity with Gift Aid during the tax year.

Step 1: Charity reclaims basic rate tax

Net donation: £1,000
Gross donation: £1,000 / 0.80 = £1,250
Charity reclaims from HMRC: £1,250 x 20% = £250
Charity receives total: £1,250

Step 2: Sarah's basic rate band is extended

Normal basic rate band: £12,571 to £50,270 (£37,700)
Extended basic rate band: £12,571 to £51,520 (£37,700 + £1,250 = £38,950)
This means £1,250 of Sarah's income that would have been taxed at 40% is now taxed at 20%

Step 3: Sarah's tax saving

Tax saving: £1,250 x (40% - 20%) = £1,250 x 20% = £250

Summary for Sarah:

| Item | Amount | |------|--------| | Sarah pays | £1,000 | | Charity receives (with Gift Aid) | £1,250 | | HMRC pays to charity | £250 | | Sarah claims back via Self Assessment | £250 | | Actual cost to Sarah | £750 |

The charity gets £1,250, and it costs Sarah only £750 after claiming her higher rate relief.

Extra Relief for Additional Rate Taxpayers (45%)

If your income exceeds £125,140 in 2025/26, you pay tax at 45% on income above that threshold. The relief for additional rate taxpayers is even more generous.

Worked Example: 45% Taxpayer

James is a self-employed IT contractor with taxable income of £160,000 in 2025/26. He donates £2,000 to charity with Gift Aid during the tax year.

Step 1: Charity reclaims basic rate tax

Net donation: £2,000
Gross donation: £2,000 / 0.80 = £2,500
Charity reclaims from HMRC: £2,500 x 20% = £500
Charity receives total: £2,500

Step 2: James claims relief through Self Assessment

James's income above £125,140 is taxed at 45%
The gross donation of £2,500 extends his basic rate band
But since his income is well above the additional rate threshold, the relief is calculated on the difference between 45% and 20%

Step 3: James's tax saving

Tax saving: £2,500 x (45% - 20%) = £2,500 x 25% = £625

Summary for James:

| Item | Amount | |------|--------| | James pays | £2,000 | | Charity receives (with Gift Aid) | £2,500 | | HMRC pays to charity | £500 | | James claims back via Self Assessment | £625 | | Actual cost to James | £1,375 |

The charity receives £2,500, and it costs James just £1,375.

A Note on Mixed Rate Taxpayers

If your income spans multiple tax bands, the relief you receive depends on which band the gross donation falls into. If £1,000 of the gross donation falls within the higher rate band and £1,500 within the additional rate band, your relief is calculated proportionally across both rates.

How to Claim on Your Self Assessment Return

Claiming higher and additional rate Gift Aid relief is done through your Self Assessment tax return. On the SA100, you will find a section specifically for charitable giving.

What to Enter

Enter the total amount you actually donated (the net amount, not the gross) during the tax year. HMRC's system grosses up the amount and calculates the additional relief automatically.

For the 2025/26 tax year, enter donations made between 6 April 2025 and 5 April 2026.

Carrying Back Donations

You can also elect to carry back donations. If you make a Gift Aid donation between 6 April 2026 and 31 January 2027 (the filing deadline for 2025/26), you can elect to treat it as if it was made in 2025/26. This is useful if:

You had higher income in the previous tax year
You want the tax relief sooner
It helps manage your personal allowance (see below)

The election is made on your tax return by entering the amount in the "Gift Aid payments carried back" box.

Gift Aid and the Personal Allowance

For taxpayers with income between £100,000 and £125,140, Gift Aid donations can help preserve your personal allowance. The personal allowance (£12,570 in 2025/26) is reduced by £1 for every £2 of income above £100,000, disappearing entirely at £125,140.

Because Gift Aid extends your basic rate band, it effectively reduces your adjusted net income for personal allowance purposes. This creates a marginal tax benefit that can be as high as 60% in this income range.

Example

If your income is £105,000, you have lost £2,500 of your personal allowance. Making gross Gift Aid donations of £5,000 would restore your full personal allowance, saving you an additional £1,000 in tax (£2,500 x 40%) on top of the standard higher rate relief.

Common Mistakes to Avoid

Not Claiming at All

The most common mistake is simply not claiming. The charity receives its 25% top-up automatically, but your additional relief only comes if you claim it through Self Assessment. HMRC does not apply it for you.

Insufficient Tax Paid

If you declare Gift Aid but have not paid enough UK income tax or Capital Gains Tax to cover the basic rate tax reclaimed by the charity, you will have to repay the shortfall. This is a particular risk for:

People with low income years
People who receive most of their income as dividends (which are taxed at different rates)
Retired individuals with income below the personal allowance

Always check that your total UK income tax and CGT liability for the year exceeds the basic rate tax that charities will reclaim on your donations.

Forgetting to Keep Records

Keep a record of every Gift Aid donation: the charity name, the date, the amount, and confirmation that you made a Gift Aid declaration. HMRC can enquire into your claim, and you need evidence to support it.

Donations to Non-Qualifying Bodies

Gift Aid only applies to donations to UK-registered charities, Community Amateur Sports Clubs (CASCs), and certain EU/EEA charities. Donations to individuals, crowdfunding campaigns, or organisations without charity registration do not qualify.
