Terms of Service

Please read these terms carefully before using our tools and content.

Last Updated: March 2026

Crucial Disclaimer

This website is for informational and educational purposes only. We are not qualified financial advisors, tax accountants, or regulated professionals. The figures, charts, and analysis provided are estimates based on publicly available UK tax legislation and HMRC guidance. You should always verify figures with HMRC or a qualified professional before making financial decisions.

1. Acceptance of Terms

By accessing and using Tax Trap Calculator ("the Site"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Site. We reserve the right to modify these terms at any time, and your continued use of the Site constitutes acceptance of any changes. We encourage you to review this page periodically.

2. Nature of Service

Tax Trap Calculator provides free, interactive tax calculation tools and educational content about the UK tax system. Our services include:

  • An interactive salary and tax calculator supporting multiple UK tax years
  • Marginal tax rate analysis and tax trap detection
  • Pension salary sacrifice modelling
  • Bonus tax analysis
  • Scenario comparison tools
  • Educational guides and news articles about UK tax policy

All tools are provided free of charge and require no registration. The Site is supported by non-intrusive advertising via Google AdSense.

3. Accuracy of Information

While we strive to keep all tax bands, thresholds, and rates up to date with the latest UK Budget announcements and HMRC publications, we cannot guarantee 100% accuracy due to the inherent complexity of individual tax affairs. Factors that may cause our estimates to differ from your actual tax position include, but are not limited to:

  • Non-standard tax codes or HMRC adjustments
  • Benefits in kind, company car assessments, or other employment benefits
  • Self-employment income, rental income, or capital gains
  • Complex pension schemes or carry-forward allowances
  • Tax relief claims, charitable giving, or other deductions not modelled by our calculator

Our calculations are based on publicly available HMRC rates and thresholds as published on gov.uk. We update our engine promptly when new tax year data is confirmed by HMRC.

4. Not Financial Advice

Nothing on this Site constitutes financial, tax, legal, or investment advice. The information and tools provided are for educational and illustrative purposes only. You should not rely on any output from our calculator as the sole basis for financial decisions.

Before making decisions about pension contributions, salary sacrifice arrangements, or tax planning strategies, we strongly recommend consulting a qualified tax professional — for example, a Chartered Accountant registered with the ICAEW or a Chartered Tax Adviser registered with the CIOT.

5. Limitation of Liability

To the fullest extent permitted by law, Tax Trap Calculator and its creators accept no liability for any direct, indirect, incidental, consequential, or special damages arising from:

  • Use of, or inability to use, the Site or its tools
  • Any errors or omissions in the calculations, guides, or articles
  • Any decisions made based on information provided by the Site
  • Any interruption or cessation of the Site's availability
