This change will come into effect from April 2023 so from the next tax year.
The current level is set at £150,000 and that was due to be frozen until 2026 this budget changed the level and froze it until 2028.
Other tax allowance levels, i.e. the level for 20% tax and 40% tax have been frozen until 2028 (previously this was also planned to be 2026).
Therefore, many more people will be pulled into the 45% tax bracket with effect from next year, to claw back some income to plug the fiscal gap which has been created recently.
The figure of £125,140 is significant as it is the level at which you no longer get any personal allowance, due to the tapering off of this after earnings reach £100,000.
The rates of income tax remain the same, with the lower rate being 20% and the higher rate being 40%. The top rate of 45% was initially going to be scrapped in Liz Truss’s fateful budget but that was scrapped and reinstated.
