Reeves Extends Threshold Freeze to 2031
Chancellor Rachel Reeves has officially extended the freeze on income tax thresholds until 2031, a move that will significantly increase tax liabilities for millions of employees as wages rise. The decision, presented in the Spring Statement, builds upon the initial Conservative freeze set to expire in 2028-29, effectively locking thresholds at current nominal levels for nearly a decade.
While the government maintains the additional revenue is essential for funding public services, economists and opposition figures characterize the policy as a "stealth tax." By preventing thresholds from adjusting for inflation and wage growth, the policy drags more earners into higher tax bands and increases the tax burden on existing brackets without a legislative change to tax rates.
Calculating the Hidden Burden
A dedicated analytical tool, utilizing Office for Budget Responsibility (OBR) forecasts from the March 2026 Spring Statement, quantifies the impact of this policy. The calculator isolates the financial consequences of the extension, comparing current payments against a hypothetical scenario where thresholds rise in line with inflation from 2026-27.
The tool projects the extra tax and National Insurance contributions (NICs) payable in the 2030-31 fiscal year. It assumes salary growth aligns with OBR forecasts for average weekly earnings, though it notes that individual wage trajectories may fluctuate due to job changes or irregular pay patterns. The calculator specifically targets employees in England, Wales, and Northern Ireland, excluding Scottish workers due to distinct tax bands and self-employed individuals who face different taxation rules.
Technical Mechanics and Limitations
The estimation engine applies precise rounding rules to ensure accuracy: the personal allowance (PA) is rounded up to the nearest £10, while the basic rate limit is rounded up to the nearest £100. The additional rate threshold is calculated to rise in line with the PA, maintaining the mechanism where the PA reduces by £1 for every £2 earned over £100,000.
Users should note several exclusions in the model. The tool does not account for exemptions for those over state pension age regarding NICs, tax relief on pension contributions, or various other allowances and tax credits. Furthermore, the calculator does not store user results, and it relies on OBR Consumer Prices Index (CPI) inflation figures for threshold calculations rather than actual future inflation data.
The extension marks a decisive shift in fiscal strategy, prioritizing revenue stability over nominal tax relief. As the government moves forward, the interplay between rising nominal wages and frozen thresholds will continue to drive up effective tax rates across the workforce, a dynamic that will be closely monitored in upcoming fiscal reviews.
