That’s because the Chancellor has opted to freeze the tax thresholds – the point at which you start paying tax, and the point at which you signal paying a higher rate of tax – for the next three years.
This is often called a secret tax because, unlike increasing the main rates, it is not apparent on your pay slip.
This will affect you most if your income is close to one of the tax thresholds, but anyone who gets a pay rise will be affected, as long as you earn enough to pay the tax.
about one million people Those who don’t currently earn enough to pay income tax will have to pay tax as soon as their earnings reach the £12,570 threshold.
This will include people living on the state pension, which is currently less than £12,000 a year but will get very close to the limit next year. According to the Institute for Fiscal Studies (IFS) think tank, part-time minimum wage earners, who work only 18 hours a week, will also have to pay income tax.
The personal allowance cap is set for the whole of the UK, so people in Scotland will also be affected, although other tax bands are different there.
People will also pay more into National Insurance Contributions (NICs) as the threshold for starting payments is also being stabilised.
How does this work?
Salaries usually increase from year to year to cover the rising cost of living. The tax cap will also generally be removed in line with rising prices.
However, because the limits are fixed, as your salary increases, a large portion of it will go over the limit and thus be taxed.
For example, if you work full-time and are paid the minimum wage, by 2030 you will pay £137 more in tax per year than those within those limits after 2028, according to the IFS.

Will I pay a higher rate?
As incomes rise, keeping the thresholds frozen also means that more people will be pulled into the higher, 40%, tax bracket.
For example, if you currently earn £49,000 and your salary increases with inflation, by 2031 you could earn £54,000, meaning some of your income will be taxed at the higher rate that applies to earnings over £50,271.

Nearly one in four taxpayers will pay some of their tax at a higher rate by 2031, according to calculations by the government’s independent forecaster.
The same principle applies to the additional, 45%, rate imposed on a person’s income above £125,140, which £600,000 more people are now expected to pay.
Will borders ever grow back?
Taxpayers are already paying hundreds of pounds more than they would have if they had been allowed to increase prices from 2021 onwards, when the previous government banned them.
Inflation has been high in recent years, making the impact of the fixed ceiling larger.
After a decade of frozen tax caps, in 2031, the policy would have raised £56bn in total, up £12bn from the three-year extension just announced. That’s money that helps pay for the NHS, schools and support for the sick, disabled and elderly.
As per the current situation, the limits are expected to increase again in 2031.
However, no matter the basic principle at stake, there is no size that is the “right” size for a tax free personal allowance. Before the financial crisis, the personal allowance before tax began to be paid was around £5,000, which is much lower than today, even allowing for inflation, and was allowed to rise until the pandemic arrived.
