What you need to know about CAT loans from Close Relatives – Mandatory Tax Filing


With effect from today, a new mandatory Capital Acquisitions Tax filing obligation is imposed on the recipients of certain loans from close relatives.



It applies to existing loans as well as new loans made since January 2024, irrespective of whether or not any tax is due.



Until 31st December 2023, there was no requirement to file a Capital Acquisitions Tax Return in respect of this type of loan, until 80% of the recipient’s group class threshold had been exceeded.



The aim of this new requirement is to provide the Revenue Commissioners with greater visibility with regard to loans between close relatives in circumstances where the loans are either interest free or are provided for below market interest rates.



The individual is deemed to have received the benefit on 31st December each year which means the relevant return must be filed on or before 31st October of the following year.  Therefore, the first mandatory filing date will be 31st October 2025.



What is a “Close Relative”?


A close relative of a person, includes persons in the CAT Group A or B thresholds, and is defined as follows:


  • a parent of the person,


  • the spouse/ civil partner of a parent of the person,


  • a lineal ancestor of the person,


  • a lineal descendant of the person,


  • a brother or sister of the person,


  • an aunt or uncle of the person, or


  • an aunt or uncle of the spouse/ civil partner of a parent of the person.




What about Loans from Private Companies?


There are certain “Look Through” provisions which must be applied to such loans.  In other words, loans made to or by private companies will be “looked through” to determine if the loan is ultimately made by a close relative.  Generally private companies are under the control of five or fewer persons.  The holding of any shares in a private company is sufficient for these provisions to apply, including where the shares in the company are held via a Trust.



If someone receives an interest free loan of say €500k from a close relative’s company, the recipient of the loan would be deemed to take the loan from their close relative. As this exceeds the €335k threshold, this loan would be reportable.



These mandatory tax filing obligations apply in the following situations:


  1. Where the loan is from a private company to a person in circumstances where the beneficial owner of the company is a close relative of the borrower.


  1. Where the loan is from a person to a private company in circumstances where the beneficial owner of the company and the lender are close relatives.


  1. Where the loan is from one private company to another private company in circumstances where the beneficial owners of both companies are close relatives.





What Loans must be Reported?


A mandatory filing obligation arises for the recipient of the loan where:


  • there is a loan between close relatives,


  • he/she is deemed to have taken an annual gift,


  • no interest has been paid on the loan within six months of the end of the calendar year and


  • the total balance on the loan and any other such loan exceeds €335,000 on at least one day during the calendar year.



Whether or not a person exceeds the €335,000 threshold would need to be considered in relation to each calendar year.



A loan is deemed to be any loan, advance or form of credit. It need not necessarily be in writing.



All specified loans must be aggregated.  Therefore, if a person has multiple loans from a number of different close relatives, the amount outstanding on each loan, in the relevant period, must be combined to determine if the threshold amount of €335,000 has been exceeded.


The first returns must be submitted by 31st October 2025 in respect of the calendar year ending 31 December 2024.





What Information must be Reported?


The CAT return must include the following information in relation to reportable loan balances:


  1. The name, address and tax reference number of the person who made the loan,


  1. The balance outstanding on the loan and


  1. All other such information as the Revenue Commissioners may reasonably require.
