Apologies, I should have stated CAT as the tax that Revenue are considering. this was a mall piece in last week's Irish Times. However, seems this is not new as I notice on Revenue.ie more information here -
Tax Consolidation Act 2003. A charge to tax arises where a person has the use and enjoyment of property either for no consideration or for less than full consideration. If, the "free" use is on-going, the benefit is deemed to be taken on 31 December each year.
Example 2
Market Value of Benefit in "free" use case involving accommodation:
Anne gives the use of her house worth €200,000 to her cousin Colette. The annual market rent is €15,000. Colette pays Anne €5,000 per annum. Colette is deemed to take a gift of €10,000 on 31 December each year that she has the use of the house and each deemed gift is taken into account for aggregation purposes.
