Plain-English terms for using the free CalcHub.uk UK tax API.
Attribution required
Any public display of data returned by the API must include a visible, do-follow link reading “Calculated by CalcHub.uk” pointing to https://calchub.uk. Free use is conditional on this.
Fair use
The pre-generated static endpoints are free to call. Please cache responses where possible. Sustained high-volume or commercial bulk use should contact us so we can keep the service fast for everyone.
No re-sale
You may not re-sell the API or repackage it as your own data product or competing API.
Provided “as is”
Figures are estimates for the current UK tax year for guidance only and are not financial, tax or legal advice. CalcHub.uk is not liable for decisions made using API output and may change calculations as UK tax rules change.
