UK Faces 'Stealth Tax' as Inflation Pushes Workers into Higher Tax Brackets

Brits are facing a significant "stealth tax" increase as surging inflation, partly attributed to the Middle East crisis, is projected to push more workers into higher tax brackets. The Institute for Fiscal Studies (IFS) estimates this effect could generate approximately £9 billion annually for the Treasury by 2029-30, with potential for even greater sums from value-added tax (VAT) and property taxes.

The current freeze on income tax thresholds, initially implemented in 2022 by the Conservative government and subsequently extended by Labour, means that as wages increase to keep pace with inflation, individuals will pay a larger proportion of their income in taxes. Even if wages do not fully match inflation, the frozen thresholds will still result in increased tax contributions.

This projected revenue windfall is seen as a crucial buffer against a significant hit to the government's financial "headroom." The margin for the government's key fiscal rule, which requires a surplus in the current budget by 2029-30, stood at £24 billion in March. However, soaring interest costs on national debt and increased spending commitments could have otherwise eroded this margin substantially.

Despite the potential for increased revenue, the IFS cautions that it would be "not credible" for Chancellor John Healey to simply retain this extra money. The report highlights that inflation will also place considerable strain on departmental spending. To avoid real-terms cuts to public services, an estimated £24 billion would be needed, while increasing defense spending to 3% of GDP by 2030 would require an additional £11 billion.

IFS director Helen Miller stated that if Mr. Healey were to fund these increases through taxation, it would necessitate a 3% rise in income tax or VAT rates. The uprating of benefits due to inflation is also expected to add approximately £10 billion to government costs. Miller emphasized that a "steady-as-she-goes" budget is not a viable option, as maintaining current tax and spending plans would effectively mean accepting significant cuts to the quantity or quality of public services, especially if defense spending is increased without additional funding.

The freeze on tax thresholds was originally set to end in April 2026 but was extended to 2028 by Jeremy Hunt, and then further extended by Rachel Reeves until April 2031. This policy is already projected to increase taxes by over £50 billion annually by the end of the decade.

Opposition parties have criticized Labour's approach. Shadow Chancellor Andrew Griffith stated that Labour has already raised taxes significantly and that families cannot afford further increases, urging them to reduce welfare spending instead of imposing more taxes on working individuals.

Reports also indicate that Mr. Healey has abandoned plans for a "warehouse tax" raid, which had been proposed by Prime Minister Andy Burnham to fund tax cuts for the hospitality sector. Plans to lower the threshold for the "mansion tax" from £2 million to £1.5 million are also reportedly shelved.
