Tax Efficient Giving
Did you know you can allow the Irish Cancer Society to claim 44.9% in tax back on your personal donations over €250, at no cost to you, our donor. That’s an additional €112.25 on top of your €250 personal donation. All you need to do is sign and return a CHY3 tax-back form so we can claim the tax back from the Revenue Commissioners.
By completing a CHY3 form, you can unlock much needed income which could fund life-saving, cancer research or the delivery of a range of services that will improve the lives of people living with cancer.

Frequently Asked Questions
After the end of any year in which your personal donations total €250 or more, we will send you a CHY3 form to complete (unless you already completed one for that period). If you are a tax payer simply complete the form and return it to the Irish Cancer Society. We will then send a claim to Revenue. When they are satisfied that you paid at least that amount in tax, they will send us the money. Please send your completed CHY3 form directly to the Irish Cancer Society, not Revenue.
Your donation will be worth an additional 44.93%. So if you donate €250 from your own personal funds, we can claim €112.33 tax back from revenue – meaning your original donation is worth €362.33 to the Irish Cancer Society.
That depends. We can only claim tax back on donations made to the Irish Cancer Society which come from you personally which do not come from a group fundraised activity and you have received no tangible benefit from (e.g. If you bought raffle tickets, raised sponsorship yourself or sponsored someone to go on an overseas trek, they would not qualify). If in doubt do get in touch and we can let you know if your donation qualifies.
Absolutely. Your details will remain completely confidential to the Irish Cancer Society and the Revenue Commissioners. The information will not be used for anything other than the tax claim. And you don’t need to tell us how much tax you pay or whether you are PAYE or self-assessed. All we need is your signature and PPS number. We will retain this number securely and only for the purposes of obtaining the tax back on your donation.
Not at all. It won’t cost you a penny in tax or affect your tax status in any way.
Yes. If you are jointly assessed as a couple either party can sign the form using either person’s PPS number.
If you have a pension, investments or any other means on which you pay either income or capital gains tax, we can claim on this amount. I’m self-employed/self-assessed – don’t I get the tax relief myself? Since 1 Jan 2013, self-assessed and PAYE taxpayers are treated the same – all tax relief goes to the charity, not the taxpayer. So, while you don’t get the relief yourself, your personal donations to the Irish Cancer Society can be worth 44.9% more, at no extra cost to you.
It doesn’t matter if you have given to other charities as well. You can send in the tax form to each charity. We only reclaim tax on the personal donations you made to the Irish Cancer Society (assuming you donated €250 or more to us from your own personal funds within a year). All charities can claim separately for donations you’ve made.
