By completing the CHY3 form, you are allowing ICRR to claim tax relief on your donation and any future donations to us for a five year period. For regular donations, no matter what the frequency, that total over €250 each year, this is an option that ensures less paperwork for you over the five-year period.
If you’d rather provide a certificate for the tax refund scheme on an annual basis, use the CHY 4 form.
