Capital Acquisitions Tax Ireland | CAT Advice and Compliance

What Is Capital Acquisitions Tax (CAT) in Ireland

Capital Acquisitions Tax (CAT) is a tax that applies when an individual receives a gift or inheritance. It is charged on the value of the benefit received, rather than on the estate of the person giving the gift or inheritance. CAT commonly arises following the transfer of property, cash, shares, land or business assets between family members or other parties.

CAT is a self-assessed tax. This means the beneficiary is responsible for calculating the tax, determining whether reliefs apply, filing the appropriate return and paying any tax due within Revenue deadlines.

Assets Commonly Subject to CAT

Capital Acquisitions Tax can apply to a wide range of assets, including residential and commercial property, farmland, cash gifts, shares, business interests and other valuable assets. CAT may also apply to indirect benefits or rights received.

The value of the gift or inheritance is assessed at market value on the valuation date, regardless of whether the asset is sold immediately.

CAT Thresholds and Relationship Groups

CAT operates on a lifetime threshold system. Each beneficiary has a tax-free threshold based on their relationship to the disponer. These thresholds apply cumulatively across all gifts and inheritances received within the same group over a lifetime.

Once the relevant threshold is exceeded, CAT is charged on the excess at the standard rate. Tracking lifetime benefits accurately is essential to ensure correct reporting and avoid underpayment.

Capital Acquisitions Tax Reliefs and Exemptions

Several reliefs may significantly reduce CAT exposure where conditions are met. Agricultural Relief and Business Relief can reduce the taxable value of qualifying assets, while the Dwelling House Exemption may apply in limited circumstances.

Relief eligibility is strictly defined, and incorrect assumptions can lead to unexpected tax liabilities. Professional advice helps ensure reliefs are applied correctly and supported by appropriate documentation.

Filing Deadlines and Compliance Obligations

CAT must be reported and paid by specific Revenue deadlines following the valuation date. Late filing or late payment can result in interest and penalties. In some cases, a CAT return may still be required even where no tax is payable, in order to track lifetime thresholds.

Maintaining accurate records of prior gifts and inheritances is critical for ongoing compliance.

Why Capital Acquisitions Tax Planning Matters

CAT planning can help families transfer wealth efficiently while minimising tax exposure. Early advice allows beneficiaries and families to understand threshold usage, relief eligibility and potential future liabilities.

Without planning, beneficiaries may face unexpected tax bills or miss opportunities to apply valuable reliefs.
