Most UK donors get tax relief on donations through Gift Aid. You sign a gift aid declaration, and the charity claims 25p for every £1 you give. Higher-rate and additional-rate taxpayers then claim the extra relief through self-assessment or a tax code change.
If by “renew tax relief on donations” you mean keeping your charity tax relief claims correct and up to date, the main UK route is still gift aid. There is no annual renewal process for donors. Instead, you claim relief by using the right method, keeping records, and following HMRC’s time limits. Since 6 April 2024, relief on donations to non-UK charities has ended, so eligibility now depends much more clearly on the charity meeting the UK tax definition.
Apex Accountants takes a simple view. This area is often treated like a small admin point, but it can affect your tax return, your adjusted net income, your High Income Child Benefit Charge position, and, in some cases, your inheritance tax planning. HMRC’s own guidance shows that the rules on tax relief on charitable donations in the UK are simple once you separate them into the correct relief route.
For most individuals, tax relief on donations is claimed through one of these routes:
Gift Aid lets a charity or community amateur sports club reclaim 25p for every £1 you donate. So a £100 donation is treated as £125 gross for tax purposes. This gift aid tax relief does not cost the donor anything extra at the point of giving.
To use Gift Aid, you must give the charity a Gift Aid declaration. That declaration can cover:
That point matters. Many people think they need to “renew” Gift Aid every year. Usually, they do not. What matters is that the declaration remains valid and that you still pay enough qualifying UK tax.
You must have paid enough income tax or capital gains tax in the tax year to cover the amount the charity reclaims. HMRC says your Gift Aid donations must not be more than 4 times the tax you paid in that year. If the charity reclaims more than you paid, HMRC may ask you to pay the difference.
This is one of the most important compliance points. A donor can complete a declaration in good faith, then later stop paying enough tax. HMRC says you must tell the charities you support if that happens.
Yes. If you pay tax at 40% or 45%, you may claim the difference between the basic-rate relief already given to the charity and your higher rate of tax. HMRC explains that this relief is given by increasing your basic rate band and higher rate band by the grossed-up amount of your gifts.
The following example shows the mechanics clearly:
This extra gift aid tax relief is the part higher-rate donors most often leave unclaimed.
If you complete a self-assessment return, enter your qualifying charitable giving on the return using HMRC’s charitable giving guidance and help sheet HS342. If you do not normally file a return, you can contact them and ask for your tax code to be adjusted. You can claim £5,000 or less by phone, and anything above £5,000 must be claimed in writing.
If you are claiming tax relief on donations of £10,000 or more without sending a tax return, HMRC says you need to tell them the following:
Yes, but the route depends on timing.
A declaration can cover donations made in the last 4 years. That helps the charity reclaim Gift Aid on qualifying donations if the declaration is valid.
HMRC allows certain Gift Aid donations made after the tax year ends to be treated as if they were made in the previous tax year, but only if you make that claim on the original return and submit it by the filing deadline. HMRC is clear that it cannot accept a first claim or a higher claim in an amended return for that carry-back treatment.
If the issue is not carry-back but overpaid tax more generally, HMRC’s overpayment relief rules may be relevant. That is a separate claims process and not a way to reopen the specific carry-back rule after the deadline.
This is the key policy change.
From April 2024, non-UK charities and CASCs are no longer eligible for UK charity tax relief. Only charities falling within the relevant UK court jurisdictions now qualify under the UK tax definition. HMRC also states in HS342 that you no longer get relief on gifts to non-UK charities after 5 April 2024.
So if you previously gave to an EU or EEA body and expected UK tax relief, you now need to re-check eligibility carefully. That is one of the main reasons people search for how to renew tax relief on donations or want to revisit their claims.
Payroll giving works differently from gift aid. The donation is taken from wages or pension before income tax is deducted. HMRC says that to donate £1, a basic-rate taxpayer pays 80p, a higher-rate taxpayer 60p, and an additional-rate taxpayer 55p.
This donation tax relief route can be simpler for regular donors because the relief is built in through payroll. You do not then claim the same higher-rate difference separately in the way you do with Gift Aid.
HMRC says you can claim relief by deducting the value of the gift from your total taxable income for the tax year in which you made the gift or sale to charity.
If the charity asks you to sell the asset on its behalf, you can still claim relief, but HMRC says you must keep the records of the gift and the charity’s request. Our guide on gifts to spouses or charity explains the Capital Gains Tax side of these gifts.
A gift to charity in your will is deducted from your estate before inheritance tax is worked out. If you leave 10% or more of the net value of the estate to charity, HMRC says the inheritance tax rate on some assets may reduce to 36%.
Yes. When working out adjusted net income, you deduct the grossed-up value of Gift Aid donations. For every £1 donated under Gift Aid, you take off £1.25 from net income.
That can matter where income-linked thresholds apply. Adjusted net income is used for rules such as the Personal Allowance taper and the High Income Child Benefit Charge.
Good records are essential if you want your charitable donations tax relief to stand up to an HMRC check. You need to keep records of donations if you want to take them off your taxable income. For land, buildings and shares, you should keep the legal transfer papers and any document showing the charity asked you to sell on its behalf. Individual taxpayers normally need to keep records for at least 22 months from the end of the tax year.
For charities, Gift Aid declarations must be kept for 6 years after the most recent donation is claimed.
Apex Accountants helps clients review their charitable donations tax relief from a tax and compliance perspective and not just a paperwork angle. That includes:
We also help clients avoid simple errors that can create HMRC problems later, especially where there are large donations, changing income levels, overseas charities, or missed filing deadlines. This review sits alongside our wider tax planning services for individuals and business owners.
The main point is this: tax relief on donations in the UK does not usually need “renewing”, but it does need checking. The right claim depends on the donation method, the tax year, the charity’s eligibility, and your own tax position. Since the April 2024 restriction to UK charities, it is even more important to confirm that a donation still qualifies before you rely on relief.
If you are unsure how your charitable donations affect your tax position, contact Apex Accountants today. Our team can review your donations, confirm eligibility under HMRC rules, and help you claim the correct tax relief on your self-assessment return.
No. One valid Gift Aid declaration covers current and future donations plus gifts from the last 4 years as long as you still pay enough UK tax.
Yes. Higher rate taxpayers who do not file a return can ask HMRC to change their tax code instead.
No. A carryback claim must be made on the original return for that year and filed by the deadline.
Usually not. From 6 April 2024, only UK charities and CASCs qualify for UK charitable tax reliefs.
Yes. Gift Aid donations reduce your adjusted net income by the grossed-up amount, which can restore part of your Personal Allowance.
No. Payroll giving comes out of your pay before tax, so the relief is automatic, and there is nothing to claim back on your return.
Keep the charity’s receipt for every donation and your Gift Aid declaration. HMRC may ask for the amount and date of each gift if it checks your return.
