Enduring Certificate CHY3 Form

By Completing the CHY3 Form, you are allowing The Charity claim tax relief on this and any future donations to The Charity for a five year period. It is more effective if you complete an Enduring Certificate (CHY3 Form) because it could make your donations over a five-year period tax-effective without the need for any further paperwork.

Annual Certificate CHY4 Form

If you prefer to provide a certificate on an annual basis then you can complete the CHY4 form.

The CHY4 form allows The Charity claim tax relief on donations to The Charity within a financial year. .

FAQ‘s

An extra 45% approx. on donations over €250. Use our calculator above to calculate the exact figure for your donation amount.

No – If you made multiple donations to the same charity over the course of 1 year, which in total are great than €250, then these are eligible for a Tax Rebate.
There is no limit to the number of eligible charities that can claim tax relief when you give each of them over €250. However, what charities are paid by Revenue cannot exceed the total tax you actually paid. If the tax you paid is less than the total being claimed by charities, Revenue will pay them on a first-come, first-served basis.
Any donations which you made yourself (not on behalf of or refunded by another party) from which you and people connected with you obtained no tangible benefit (e.g. if you bought raffle tickets, raised sponsorship yourself or sponsored someone to go on an overseas trek, they would not qualify).
You are NOT required to provide any details of your income or tax paid. All that’s required is your signature and PPS number, which you can find on most tax/social welfare documents addressed to you. The charity will retain this number securely and only for the purposes of obtaining tax rebates on your donations.
If you have a pension, investments or any other income on which you pay either income tax or capital gains tax, that’s eligible for tax relief.
CHY3 enduring certificate simply enables the charity to claim tax relief if you donate €250+ in any of the five years covered by the form. It simplifies the tax relief process for both you the donor and the charity. It’s the most effective method for charities to claim the tax rebate. Note it does NOT commit you to making donations to the charity.

CHY4 Annual Certificate only allows the charity to claim tax relief for the year in which you made the donation. If you donate to the charity in any following year, you will need to complete the CHY4 form again.

Yes, and you will be able to do so without further paperwork. The charity may contact you by phone or email. It would be helpful if you supplied your phone number and/or email on the CHY3 form.
Yes – send an email to the charity directly, asking them to cancel the enduring certificate.
Only charities authorised by Revenue can apply for Tax Rebates. A list can be found here on the Revenue website. For more details from the Revenue website click here
After the end of any financial year in which your donations total €250+, the charity will send you the relevant Forms (CHY3/4) to complete unless you already completed one for that period. The charity will then claim the rebate. When Revenue are satisfied you paid at least that amount in tax, they will pay the charity. Please send the completed form to the charity, not Revenue.
Donations over €250 and under €1,000,000 qualify.
We forward your form to the beneficiary charity within 2 months. The charity will then submit the form to the revenue. iDonate Ltd. will not copy or keep any record or data on your completed form.
