The government has announced that the threshold for paying income tax at the additional (45%) rate will be reduced from 6 April 2023. The following is an extract from the HM Treasury document CP751, entitled Autumn Statement 2022 (para. 5.20), with paragraph spacing added for greater clarity:
“The income tax additional rate threshold (ART) will be lowered from £150,000 to £125,140 from 6 April 2023.
The ART for non-savings and non-dividend income will apply to taxpayers in England, Wales, and Northern Ireland.
The ART for savings and dividend income will apply UK-wide.
The government will legislate in Autumn Finance Bill 2022.”
