Taxes Consolidation Act 1997 section 959AQ

Date for payment of capital gains tax

Section 959AQ sets out the due dates for payment of capital gains tax, splitting the tax year into an initial period and a later period with separate deadlines for each.

• CGT on gains arising in the initial period (1 January to 30 November) is due on or before 15 December in the same tax year.
• CGT on gains arising in the later period (1 December to 31 December) is due on or before 31 January in the following tax year.
• Where a subsequent assessment issues, the tax shown on that assessment is deemed to have been due and payable on the same dates as applied to the initial and later periods.
• These payment obligations apply regardless of whether a formal assessment has been made at the time the tax falls due.
