The Irish CAT Rate
The €3,000 small gift exemption
You can give someone €3,000 every calendar year, per giver, completely CAT-free - and it doesn’t use up any of their lifetime Group A/B/C threshold. So two parents can give a child €6,000 per year tax-free (and more if each parent also gifts the child’s partner).
You generally must pay CAT and file the IT38 by October 31st in the same year if the valuation date is January 1st to August 31st. If the valuation date is September 1st to Deccember 31st, CAT is payable by October 31st of the following year.
If the total taxable value of gifts/inheritances you’ve taken in a group exceeds 80% of the relevant group threshold, you must file an IT38 - even if you don’t have a CAT liability.
To apply the 80% test and to compute CAT, you must aggregate taxable benefits received within the same group since 5 December 1991.
Keep contracts, purchase/sale documents, costs, valuations and calculations for at least 6 years, in case Revenue queries the figures.

CAT is Ireland’s tax on gifts and inheritances. The beneficiary (the person receiving the gift/inheritance) is the person who may need to file an IT38 and pay CAT, depending on thresholds and exemptions.
CAT is charged at a flat 33% on the taxable amount of a gift or inheritance above the relevant group threshold.
CAT uses three lifetime tax-free thresholds based on your relationship to the disponer. Current thresholds (for benefits on/after 2 Oct 2024) are: Group A €400,000, Group B €40,000, Group C €20,000.
To work out if you’ve used up your threshold, you must aggregate the taxable value of all prior gifts/inheritances you’ve received in the same group since 5 December 1991.
You must file an IT38 if the total taxable value of benefits you’ve received in the group exceeds 80% of the relevant group threshold — even if no CAT is payable.
The valuation date is the date the value of the benefit is established, and it drives the deadline:
Yes — a gift or inheritance from your spouse or civil partner is exempt from CAT.
The Small Gift Exemption allows annual gifts of up to €3,000 per donor per recipient per calendar year to be CAT-free. An IT38 return isn’t required just to claim this exemption (unless other filing conditions apply).
CAT can apply where (a) the disponer is resident/ordinarily resident, (b) the beneficiary is resident/ordinarily resident, or (c) the property is situated in Ireland. If neither party is resident/ordinarily resident, CAT generally applies to Irish-situated assets only.
Common reliefs/exemptions that can significantly reduce CAT (subject to conditions) include:
