# How to make the most of your charitable giving in your self-assessment: CAF shares advice - Link: https://fundraising.co.uk/2023/01/26/how-to-make-the-most-of-your-charitable-giving-in-your-self-assessment-caf-shares-advice/ - Published: 2023-01-26T12:22:47+00:00 - Author: Melanie May **With the self-assessment deadline looming (31 January), Charities Aid Foundation is encouraging people to declare their donations in their tax return to help charities.** New research from [CAF](https://www.cafonline.org/) shows that just over half (54%) of donors said they claimed Gift Aid when they gave money to charity last year. Although the number of donors using Gift Aid has risen slightly over the past few years, it is still underused by many who pay income tax, and charities currently miss out on £500 million in Gift Aid which is unclaimed every year.  #### Gift Aid With more than 12 million people who are self-employed or earn over £100,000 due to complete a Self Assessment tax return before the deadline on 31 January, CAF is encouraging them to claim Gift Aid relief on their donations. ## Advertisement #### Personal tax relief Higher rate taxpayers who complete a Self Assessment can also claim back the difference between higher rate and basic rate tax on the value of their donations in personal tax relief.  For a 40% rate taxpayer this means that for every £10 donated, an extra £2.50 will go to the charity in Gift Aid, and they can claim back another £2.50 provided they made a Gift Aid declaration to the charity.  Just over half (54%) of those with an income over £50,000 a year are aware they can claim tax relief on donations to charity, while a third (35%) are unaware. Individuals can also claim for relief for four years’ worth of previous donations through tax‘ overpayment relief’ with HMRC. Mark Greer, Managing Director for Philanthropy Services, Charities Aid Foundation, said: > “Charities miss out on millions every year from generous donors who forget to > tick the Gift Aid box. > “With the cost-of-living causing many to cut-back, there are some relatively simple > ways to make sure the charities you care about are getting the most from your > donation. If you haven’t already, make a Gift Aid declaration to the charity. > If you complete a Self Assessment and are a higher rate taxpayer, you may also > be entitled to personal tax relief and you can also check whether you can claim > for donations in previous years.” #### CAF advice CAF has issued this advice to help more people make the most of their charitable giving in their Self Assessment: 1. **Declare your donation to claim Gift Aid** Anyone paying income tax who donates money to a charity can enhance their donation by signing a Gift Aid declaration. The charity can then reclaim the basic rate tax already paid on that donation. Higher or additional rate taxpayers who fill in a Self Assessment form can also claim back the difference between the higher rate and basic rate on the value of their donations as personal tax relief or to increase their donation. 2. **Claim tax relief for previous years** If you forget to claim tax relief, or were unaware you could, then you have four years to submit a claim for tax ‘overpayment relief’ to HMRC. That’s four years after the end of the tax year your claim relates to. 3. **Declare if you gave shares to charity** This is a relatively little-known way to give to charity but it is also very tax effective. You can give shares directly to charity as long as they are listed on a recognised stock exchange. Donors will get full tax relief on any capital gains tax. You can also claim income tax relief on the fair market value of shares. 4. **Claim Gift Aid sooner** Self Assessment tax returns normally only include items from the previous tax year. But for Gift Aid, you can also claim tax relief on donations made in the current tax year (up to the date the return is sent) to either get the tax relief sooner, or if you will not be paying higher rate tax in the current year but have paid it in the previous year. 5. **Let charities know if your circumstances change** The amount of tax you pay needs to be at least equal to the value of Gift Aid the charity will claim on your donations. If circumstances change and you no longer pay enough tax, it’s important to tell all the charities you support. If you don’t tell them and they continue claiming Gift Aid, you may need to pay any difference back to HMRC. * **[Charities launch campaign to revive payroll giving in companies](https://fundraising.co.uk/2025/02/04/charities-launch-campaign-to-revive-payroll-giving-in-companies/)**( 4 February 2025) * **[HMRC reports 240 crypto millionaires in new tax data](https://fundraising.co.uk/2026/09/02/hmrc-reports-240-crypto-millionaires-in-new-tax-data/)**( 2 September 2026) * **[DSC to run regional tax-effective giving training courses](https://fundraising.co.uk/2004/04/21/dsc-run-regional-taxeffective-giving-training-courses/)**( 21 April 2004)
