It will see the earnings level at which you become liable to pay income tax and national insurance (£12,570 a year) increase in line with inflation.
The freeze on higher and additional rate income tax bands will also end.
This adjustment means that individuals earning between £15,000 and £35,000 annually will save £71 per year in income tax and National Insurance, assuming a 2% increase to the thresholds.
For those with incomes exceeding £60,000 per year, the savings could amount to up to £211 a year starting in 2028.
Shaun Moore, personal tax expert at Quilter: “Despite widespread speculation that Labour would break its pledge not to raise taxes for working people by extending the income tax threshold freeze beyond 2028, the Chancellor has confirmed that the freeze will thaw as originally intended.
“This decision brings relief to many taxpayers who were concerned about the potential for prolonged fiscal drag.”
You currently pay no income tax on the first £12,570 of your earnings.
This is known as the personal allowance.
You then pay tax at 20% on income over this and up to £50,271.
Then, on earnings over that and up to £150,000, pay 40%.
The threshold at which employees begin paying National Insurance contributions (NICs) is also set at £12,570 per year.
Most people pay 8% NICs on earnings between £242 and £967 a week.
Plus, you have to pay 2% on anything you earn over £967 a week – or £4,189 per month.
Like the personal allowance, the NICs threshold has been frozen since 2021.
