Britain’s overall tax burden is expected to climb to a new record as a consequence of frozen personal tax thresholds, according to projections from the Office for Budget Responsibility (OBR). The analysis suggests the measure will draw millions more individuals into higher tax bands or into paying tax for the first time.
This shift is projected to generate substantial additional revenue for the Treasury while raising questions about the broader impacts on economic growth and household incomes.
The new data emerges as policymakers grapple with the implications of rising unemployment, global instability, and energy price volatility.
Tax Revenue Forecasts Point to Significant Increase
Forecasts from the OBR indicate that the UK’s annual tax revenues will reach £1.4 trillion by the start of the next decade, up from £1.2 trillion at present. This sums to 38.5 percent of gross domestic product (GDP), a notable rise from 36.3 percent in the current financial year.
The OBR numbers exceed previous estimates made at the time of the Autumn Statement, reflecting the amplified impact of policy decisions to hold thresholds steady. The record tax-take is driven in part by stagnant allowances.
The OBR stated, “Rising income tax revenues account for nearly half of the rise in receipts as a share of GDP, reflecting the freezing of personal tax thresholds until the end of 2030-31.”
Historical Context and Current Comparisons
Britain’s projected tax burden will surpass the previous post-war record of 37.2 percent set in 1948-49, a period marked by efforts to reduce debt accumulated during the Second World War.
The OBR’s current forecast places the tax-to-GDP ratio not only above this historical peak but also above more recent expectations, raising questions about the sustainability of the fiscal stance and its economic impact.
Income Tax Threshold Freeze Expands Taxpayer Base
The decision to extend the freeze on personal income tax thresholds, confirmed in the Autumn Statement, means that more individuals will enter the tax system as their nominal incomes rise. The OBR estimates the policy will increase the number of income tax payers to 44.6 million by 2030-31, about 6.1 million more than if thresholds had grown in line with inflation. Additionally, the OBR forecasts that the freeze will bring in £67 billion annually by the end of the decade. The tax base expansion will be felt most among employees experiencing pay increases that do not keep pace with actual inflation, effectively reducing the purchasing power of their earnings.
Pensioners and New Tax Liabilities
The changes will also affect retirees. As the full new state pension is expected to exceed the £12,570 personal allowance in the coming financial year, an estimated one million additional pensioners could become liable for income tax, according to the OBR. This figure includes those with no private income, subjecting even pension-only recipients to taxation. While the Chancellor has stated that individuals whose sole income is the state pension will not be subject to income tax, the OBR reported that it has not been provided with detailed implementation plans for such exemptions. As a result, it has been unable to quantify the precise impact of potential reliefs for pensioners.
Implications for Higher-Rate Taxpayers
The threshold freeze will also increase the number of individuals paying higher and additional tax rates. By 2030-31, an estimated 4.8 million more people will fall into the 40 percent rate band, while a further 600,000 are projected to pay the 45 percent rate. This will expand the cohort of individuals subject to the additional rate, a tax initially intended for the highest earners. Cumulatively, income tax and National Insurance receipts are forecast to reach £677 billion annually by the end of the decade, up from £535 billion this year. This marked increase will play a major role in Treasury finances, though the OBR has warned of possible economic consequences.
Final Summary
Britain’s tax burden is forecast to rise to historically high levels, driven in large part by the continued freeze on personal tax thresholds. The OBR projects this will expand the taxpayer base while raising significant additional revenue for the Treasury, but warns of potential consequences for economic growth and disposable incomes. Key uncertainties remain regarding the impact on pensioners and other vulnerable groups, while wider risks from unemployment and geopolitical tensions compound concerns about economic resilience.
