What is a stealth tax? UK examples explained

A stealth tax is a tax increase that raises your bill without raising the headline tax rate, often by freezing thresholds or cutting tax-free allowances.

“Stealth tax” is a political label, rather than a separate legal category of tax.

How can tax rise without a higher rate?

The rate is only part of the calculation. A threshold sets where tax starts or a higher rate applies. An allowance sets how much income or gain can escape a charge. Keeping these amounts fixed while prices and cash incomes rise can increase the share of income paid in tax.

That process is called fiscal drag. The IFS explained on 14 November 2025 that someone whose earnings only keep pace with inflation can still pay a larger share in tax when thresholds stay frozen. Their buying power before tax has not improved.

Use the fiscal drag calculator for an estimate based on your salary. This page explains the broader label and the main examples.

Which Income Tax and NI thresholds are frozen?

HMRC’s policy paper of 26 November 2025 keeps the personal allowance at £12,570 and the main higher-rate threshold at £50,270 until 5 April 2031. The allowance is the usual amount of income you can receive before Income Tax starts.

The personal allowance applies across the UK. The £50,270 earnings threshold applies in England, Wales and Northern Ireland. Scotland sets its own bands for earnings and pension income.

The same HMRC paper keeps the main employee National Insurance (NI) starting threshold aligned with £12,570 and its upper earnings limit aligned with £50,270 until April 2031. Equivalent limits apply to self-employed Class 4 NI. Future NI limits are set through annual regulations.

The Treasury’s Budget 2025 document also holds the employer NI starting threshold at £5,000 until April 2031. Employer NI is a separate charge from the employee deduction shown on a payslip.

How much extra revenue does the OBR expect?

In Box 3.3 of its 26 November 2025 forecast, the Office for Budget Responsibility (OBR) estimated £66.6 billion of extra annual receipts in 2030-31 from the combined threshold measures. Of that, £12.7 billion came from the extensions announced at that Budget.

These are forecasts against inflation-linked thresholds, not a running total of money already collected. The combined figure includes earlier threshold changes as well as freezes, including the earlier NI starting-threshold increase and additional-rate threshold cut.

The same November forecast estimated that, by 2030-31, the freezes would bring 5.2 million extra people into Income Tax, move 4.8 million more into the higher rate and 600,000 more into the additional rate. Do not add these groups to make a single taxpayer total.

The OBR’s 3 March 2026 forecast then raised its estimate of people brought into tax by 1 million in 2030-31 after improving its pensioner modelling. The November figures therefore need that later qualification. Revenue and taxpayer forecasts change as incomes, inflation and methods change.

The Departures board keeps other official series separate from reported individual moves.

Why is the £100,000 allowance taper an example?

The starting point for withdrawing the personal allowance has stayed at £100,000 since 2010-11. HMRC’s PAYE11110 manual, updated 2 October 2026, records its introduction at that level. HMRC’s current allowance table, updated 6 April 2026, still uses the same limit.

Above it, the allowance falls by £1 for every £2 of adjusted net income, broadly income after certain reliefs. As pay rises over time, more people can reach a limit that has not risen with prices. The £100k tax trap guide and calculator explains the calculation and pension treatment.

What has happened to Inheritance Tax allowances?

HMRC’s threshold table, updated 6 April 2026, shows the main nil-rate band at £325,000 from 6 April 2009 to 5 April 2031. The nil-rate band is the amount of an estate that can be taxed at zero before other reliefs are considered.

HMRC’s 26 November 2025 policy paper also freezes the separate residence nil-rate band at £175,000 through 2030-31. That extra allowance has conditions, including a qualifying home passing to direct descendants. It is not available to every estate.

Rising asset values can expose more of an estate to tax while these allowances stay fixed. A frozen band alone does not tell you whether a particular estate owes tax.

How were dividend and capital gains allowances cut?

HMRC announced on 21 November 2022 that the dividend allowance would fall from £2,000 to £1,000 in April 2023 and then to £500 in April 2024. Its PAYE130030 manual, updated 2 October 2026, confirms that sequence and the continuing £500 allowance. Dividends on shares held in an ISA remain tax-free.

HMRC’s Capital Gains Tax table, updated 13 April 2026, shows the annual exempt amount for individuals falling from £12,300 in 2022-23 to £6,000 in 2023-24 and £3,000 from 2024-25, including 2026-27. It applies to gains, rather than the whole sale price. Trust allowances differ.

These cuts widen the amount exposed to tax. They were published policy changes: calling them stealth taxes is a judgement about how visible the increase feels, not evidence that the rules were secret.

What should readers check after the Budget?

The Budget tracker records the 28 October 2026 announcements. Earlier figures in this article retain their original sources and dates.

What else do readers ask?

What does stealth tax mean?

It means a tax increase delivered through less visible changes, such as frozen thresholds or smaller allowances, rather than a higher headline rate. It is a political label.

Is a stealth tax the same as fiscal drag?

Fiscal drag is one mechanism: rising cash incomes cross frozen thresholds. The broader political label can also cover cuts to tax-free allowances.

Are UK Income Tax thresholds frozen until 2031?

HMRC announced on 26 November 2025 that the personal allowance and main higher-rate threshold would stay fixed until 5 April 2031. Scotland sets its own bands for earnings.

Does a frozen threshold mean everyone pays more tax?

No. It depends on income, allowances and other tax changes. A freeze can increase tax compared with thresholds rising with prices, even when earnings only keep pace with inflation.
