Keep the actual eligible donation and any grossed-up figure separate. A £100 Gift Aid donation is generally £125 gross, and further relief depends on your tax position. Payroll Giving and other donation routes must not be claimed again as ordinary Gift Aid.
Start with the donation actually made
Under Gift Aid, the charity can reclaim basic-rate tax on an eligible donation. A £100 qualifying donation is generally treated as £125 gross. People entitled to higher or additional-rate relief may claim the further difference through the appropriate route.
Give your accountant the actual amount paid and explain whether a statement already shows a grossed-up figure. Entering an amount already grossed up as if it were the cash donation can overstate the claim.
Check that enough tax has been paid
You must have paid enough UK Income Tax or Capital Gains Tax to cover the Gift Aid reclaimed on your donations for the year. If not, you can be responsible for the difference. A signed declaration does not remove that condition.
This can matter where income falls, allowances eliminate tax or someone makes a large donation in a year with little taxable income. Review the position rather than assuming every charity payment qualifies automatically.
Separate other giving arrangements
Payroll Giving already receives relief through payroll and should not be claimed again as an ordinary Gift Aid donation. Memberships, purchases and donations with benefits can have conditions. Shares or land given to charity involve different relief rules from cash Gift Aid.
For example, a fundraising statement showing a payment total should be checked against the charity's eligible Gift Aid amount, especially where tickets or goods were supplied.
Check timing before submitting
There are specific rules for treating certain current-year donations as made in the previous year. Any such claim needs checking before the original return is submitted; it should not be assumed available through a later amendment.
Supply TaxSimba with donation dates, amounts, charity statements and details of any other giving route. The accountant can review the claim alongside your other income and reliefs, so the same donation is neither omitted nor counted twice.
Further relief is not a second charity payment
In a straightforward example, £100 paid under Gift Aid is £125 gross. If the whole donation qualifies for relief at a 40% rate, the additional relief is £25: the 20 percentage-point difference applied to £125. This assumes the necessary tax and donation conditions; different rates and circumstances change the result. Give the accountant the cash donation rather than multiplying it twice.
Check the home nation used for your tax calculation
Tell the accountant whether you live in England, Scotland, Wales or Northern Ireland, and about any moves during the tax year. Scottish rates differ for wages, pensions and most other taxable income; savings and dividends use UK rules. Welsh rates are set separately. Use the rules for the relevant year and your actual taxpayer status.
See Scottish Income Tax and Welsh Income Tax. These differences do not make a London address or an England-only earnings example appropriate for everyone.
Separate the donation paid from its gross figure
Illustrative preparation example.
For a £100 eligible Gift Aid donation, record the £100 paid separately from the generally £125 gross amount. Keep payroll giving outside that ordinary Gift Aid total. Entering both as separate donations would overstate what was given.
Check: Which payments qualify, and what evidence supports the figure used?
| Check | Practical action |
|---|---|
| Cash amount or already grossed-up figure? | Keep the statement labels clear to avoid grossing up twice. |
| Was enough qualifying UK tax paid? | Check the condition across the year's eligible donations. |
| Is another giving method or carry-back involved? | Separate Payroll Giving and check the specific timing and claim rules. |
Can Payroll Giving be claimed again as ordinary Gift Aid?
No. It has a different relief route. Provide the payroll evidence and avoid a duplicate claim.
Does signing a declaration remove the tax-paid requirement?
No. The donor can be responsible for a shortfall if insufficient qualifying UK tax was paid.
