Overpayment of Capital Acquisitions Tax (CAT)

If you overpay your Capital Acquisition Tax (CAT), you may apply for a repayment. A repayment of tax may include any:

  • interest charged
  • surcharge imposed
  • or
  • penalty incurred.

Your application must be a valid claim for repayment. This means that for the year the claim is being made:

  • you may be required to file an IT38 return or an amended IT38 return
  • and
  • you should submit all relevant information to enable Revenue to determine if a repayment is due.   

A time limit applies to repayment claims. No repayment will be made unless a valid claim is submitted within the period of four years commencing on the:

  • 31 December in the year in which the tax was due to be paid
  • valuation date, in the case of Discretionary Trust Tax (DTT)
  • or
  • date of payment, where DTT was paid within four months of the valuation date.
