The quarterly returns for the 2023 tax charge year are due as follows:
- 1st quarter return due 31 March 2023 (or 5 March 2023 if submitted manually and 90 days after registration if registered after the due dates, 31 March and 5 March).
- 2nd quarter return due on 30 June 2023.
- 3rd quarter return due on 30 September 2023.
- 4th quarter return due on 31 December 2023
The personal income tax return needs to be submitted by 21 June following the end of the tax year. For example, the personal income tax return for the 2022 tax charge year must be submitted by 21 June 2023.
The same deadline applies for paying the balance of income tax that remains outstanding.
