How it works

The Government-approved tax back scheme allows charities like the Irish Cancer Society to claim 44.9% in tax back on donations over €250, at no cost to you, our donor. 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. You can also complete the CHY3 tax-back-form online here.

The form is valid for 5 years (unless you chose to cancel it), which helps lower our admin costs – allowing for greater impact in the work we do to improve the lives of those affected by cancer.

With this scheme we have the potential to 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. But we cannot do anything unless you sign and return your tax-back form today.

Do you qualify?

In order for us to claim tax back on your donations you must have donated €250 or more to the Irish Cancer Society within one year, in the last four years (2013-2016)

You can make your donation as a once-off donation or by instalments. For example, a monthly gift of €21 over 12 months totals €252, and qualifies for the tax back scheme. This only applies to personal gifts, and not to funds raised through sponsorship.

It doesn’t matter if you’re PAYE or self-assessed. Since 2013, self-assessed tax payers can no longer claim tax back on charitable donations – only the charity can make this claim from Revenue.

How your tax helps

We can claim 44.9% in tax back on donations over €250, at no cost to you. That’s an additional €112.25 on top of your €250 donation.

And it all adds up. An extra €100 can help provide comprehensive manuals and family information booklets for every Night Nurse across the country. Just sign the form. It really is that simple!
