Hi Gordon
I find the Revenue website confusing. I thought it was quite a limited exemption?
Qualifying conditions on, or after, 25 December 2016
You will be exempt from Capital Acquisitions Tax (CAT) on the inheritance of a dwelling house if, at the date of the inheritance:
the house was the only or main home of the person who died (this condition does not apply if you are a dependent relative)
you lived in the house as your only or main home for the three years immediately before the date of the inheritance
you do not own, or have an interest in, any other house
If a man has lived with his father for three years and inherits the family home, he is exempt from CAT.
But if he has lived in a house he didn't own, and inherited the family home, he would not be exempt.
If he owns his own home, he is not exempt - but that is fine, he can sell his own home and pay the CAT.
If his own home was let out and he had a big mortgage, he might not be able to pay the CAT.
In that case, Revenue charges 8% a year.
