When is CGT due?

For CGT purposes, the tax year is divided into two parts.

• Part 1('initial period') - 1 January to 30 November
• Part 2 ('later period') - 1 December to 31 December

For disposals in the initial period CGT payments are due by 15 December in the same tax year. CGT for disposals in the later period are due by 31 January in the following tax year.

For example, if George disposes of his shares in June 2023, he must pay the CGT due to Revenue by 15 December 2023. Had George held on to his shares and dispose of them in December 2023, his CGT would have been due on 31 January 2024.

If you do not pay the CGT liability by the due date or if the tax payment is less than the required amount, interest may be charged on the outstanding amount.
