Capital Acquisition Tax

Capital Acquisitions Tax (CAT) is a tax on gifts or inheritances. Transfers between spouses and civil partners are exempt from CAT.

If you get a gift or inheritance from a relative, it is tax free up to a certain amount depending on the relationship.

If you get a gift or inheritance from your cohabitant, it is taxed in the same way as if it was from someone who is not related to you. The lowest tax-free threshold applies.

If your cohabiting partner dies when you are still in a relationship together, you may be able to apply to court for a portion of their estate. A gift or inheritance is exempt from CAT if it is made by court order in this way under the redress scheme for cohabiting couples.

Tax reliefs for former cohabitants

If your cohabiting relationship ends, you may be entitled to tax relief if a court orders:

  • You to make maintenance payments to your former partner
  • A transfer of assets between you

To be a qualifying cohabitant for these reliefs you must have been cohabiting for at least:

  • 5 years or
  • 2 years if you are the parents of a dependent child

Maintenance payments

If you make legally enforceable maintenance payments to benefit your former partner, you can deduct them from your income to reduce the tax you pay.

Property transfers
