The Stealth Invaler on employees from the middle class has pushed the number of higher taxpayers more than five million for the first time.
According to official figures, an additional 680,000 people in the tax bracket of 40 percent were towed compared to a year earlier.
The monument comes in the midst of the fear that Rachel Reeves will expand an 'absurd' profit threshold this month in its mini budget this month, despite the promising of no further tax increases.
Economists said that such a movement would increase the financial burden for millions, struggling families and discourages hard work.
The latest statistics for 2022/23 are just the 'top of the iceberg', they warned. The total number of taxpayers at a higher speed is on their way to touch nine million by 2028 and some have speculated that it could reach ten million by the end of the decade.
Income tax brackets were put on ice in 2021 by Rishi Sunak when he was a chancellor to help connect the gaps in the finances of the country after the COVID-19 Pandemie.
The policy should run until 2026, but was later expanded by Jeremy Hunt until 2028.
Tax thresholds usually go up in accordance with inflation. If they don't, more people are drawn in higher ties as their salaries rise in a process known as tax resistance.

The total number of taxpayers with a higher rate is on their way to hit 9 million by 2028 and some economists have estimated that it could reach 10 million by the end of the decade
In October the Chancellor promised to end the freezing, and said that an extension would “harm working people.”
But experts said that Mrs. Reeves can be forced to trace on March 26, when she is also expected to make enormous cuts.
This is because the budget watchdog has been set to confirm that her £ 10 billion in tax headroom has been wiped out since the budget.
Darwin Friend, of the alliance of the taxpayers, said: 'The idea of ​​a higher tax level is always absurd, given the number of taxpayers that are forced to pay it.
'Frozen thresholds and high inflation means that even many struggling households are now being hit.
“Rachel Reeves urgently needs to increase the 40P threshold to give taxpayers a break and to stop this absurd discouragement to hard work.”
An income tax rate of 40 percent – or 40p for each pound – applies to a profit of more than £ 50.271. Figures published by HM Revenue & Customs showed that 5.1 million people paid the higher rate in 2022/23 – an increase of 15 percent on the previous year.
They formed 15 percent of all taxpayers and accounted for 35 percent of the total amount that was collected from income tax during the year.

Economist Julian Jessop said: 'The leap in the number of higher taxpayers is just the tip of the iceberg.
'The continuous freezing of personal tax allowances can drag four million people to the net by 2028. Moreover, there is already a speculation that Rachel Reeves will extend the freezing of two years in an emergency budget later this month.
“This can bring the total number of higher taxpayers to ten million.”
Tom Clougherty, executive director of the Institute for Economic Affairs, said: 'Since 1990, the percentage of the adult population that pays the higher or extra income tax has tripled.
'More employees who pay higher tax rates is a problem for the economy because it reduces the incentive for people to increase their income – or even to build their future earning potential. The result is less dynamics and less growth.

Experts said the Chancellor can be forced to return on March 26, if she is also expected to make enormous expenditure cuts
“The government is currently confronted with a very difficult tax situation, but there must be a long -term plan that would bring us back to lower, flatter, simpler taxes.”
The HMRC figures also showed the number of people who paid the extra tax rate of 45 percent on the profit above £ 125.140 HIT 600,000 in 2022/23 – an increase of 9.5 percent.
And a freezing of the threshold for personal allowance – which means that income up to £ 12,570 is not taxed at all – resulted in 1.5 million more people who paid income tax.
