Terms of use
Last updated 30 September 2026.
About these terms
These terms cover your use of IR35.org, including the take-home pay calculator and the contract jobs board. By using the site, you agree to them.
Estimates, not advice
The calculator provides estimates only. It should not be relied on for tax returns, contract decisions or any other financial decision. Tax rates, allowances and rules can change, and individual circumstances vary.
Speak to a qualified accountant or tax adviser for advice about your own situation. We accept no responsibility for decisions made based on these calculations.
Contract jobs
Job listings come from job boards, agencies and employers. IR35 status is taken from the advert and may be missing, out of date or wrong. A listing is not an offer of work from IR35.org.
Apply links leave this site. Check the role, the rate and the IR35 status with the hirer before you apply or accept work.
Using the site
The site is free to use. Do not misuse it, try to disrupt it, or scrape it in a way that puts an unreasonable load on it. We can change, suspend or remove the calculator, the jobs board or these terms.
Liability
The site is provided as it is. We are not responsible for loss caused by using the calculator, the jobs board, or sites we link to. Nothing in these terms limits liability that the law does not allow us to limit.
Law
These terms are governed by the laws of England and Wales.
