The Chancellor, Rachel Reeves, recently delivered her Spring Statement, offering insights into the economy and updated forecasts for inflation and wage growth over the next five years. While wages are projected to increase, you may find yourself facing higher tax bills due to frozen thresholds—those critical points at which your income tax and National Insurance contributions rise.

Originally, the Conservative government froze these thresholds until 2028-29, but Labour has since extended them until 2031. This decision raises additional revenue for public services but is frequently termed a stealth tax by economists, as it boosts tax income without altering the official tax rates.

How to Use Our Tax Calculator

To understand the potential impact on your take-home pay, utilize our tax calculator below. This tool is specifically designed for employees in England, Wales, and Northern Ireland. Please note that tax bands differ in Scotland, and self-employed individuals have different tax considerations.

How the Calculator Works

Estimation of Additional Tax and NICs: This calculator evaluates how much extra income tax and National Insurance contributions (NICs) you will incur by the 2030-31 tax year due to the frozen thresholds. Leveraging official forecasts from the Office for Budget Responsibility (OBR) for the March 2026 Spring Statement, it compares your potential tax burden against a scenario where thresholds were allowed to increase from 2026-27.

No Data Storage: Your results will not be stored by this calculator, ensuring your privacy.

Limitations of the Calculator

While this calculator provides a snapshot of the impact of frozen tax thresholds on your finances, several other variables can influence your overall tax bill. Consider the following:

Eligibility for NIC Exemption: If you are over the state pension age, you may be exempt from paying NICs.
Pension Contributions: You could receive tax relief on pension contributions.
Other Taxes and Credits: The calculator does not include other taxes you may owe or potential tax credits and allowances you might claim. It applies solely to employees in England, Wales, and Northern Ireland, while Scotland’s tax bands are different.

How Earnings and Tax Thresholds are Calculated

Projected Earnings Growth: The calculator assumes your salary will increase in line with the OBR’s financial year forecasts for average weekly earnings growth. This projection represents the OBR’s best estimate for future wage trends, and actual wage growth may vary. The calculator also assumes stability in your salary; changes in employment or income fluctuations could alter these estimates.

Tax Threshold Estimates: The calculation of future tax thresholds is based on the same Consumer Prices Index (CPI) inflation figures used by the OBR. Keep in mind that actual inflation rates could differ. The personal allowance (PA) is rounded to the nearest £10, while the basic rate limit is rounded to the nearest £100. Additionally, the additional rate threshold rises in accordance with the PA, which means that your PA decreases by £1 for every £2 earned over £100,000.

Conclusion

Understanding the impact of the Spring Statement on your finances is crucial, especially in light of the frozen tax thresholds. Use our tax calculator to gauge how these changes might affect your tax obligations as your salary increases. It’s a vital resource to help you plan your personal finances effectively in the coming years.
