BIK1. What the service provides
BIK Tax Calculator supplies general UK company car tax information and estimates based on values you enter. It does not provide an HMRC filing service, manage payroll, broker a vehicle agreement or create a tax-adviser relationship.
Use the tool to compare scenarios and understand the method. For a filing, employment arrangement or financial commitment, check the underlying information with HMRC, your payroll team or an appropriately qualified adviser.
2. Your inputs and interpretation
You are responsible for using the correct tax year, P11D value, certified vehicle details and relevant options. A wrong input can produce a plausible-looking but unsuitable result. Read the assumptions next to the calculator rather than relying on the monthly total alone.
The disclaimer explains excluded cases. Tax rules, published guidance and your personal circumstances can change. An earlier result is not a guarantee of a later tax bill.
3. Fair use
You may use the calculator and print results for personal or internal business planning. Do not use the website to attempt unauthorised access, interfere with its operation, introduce malicious code or deliberately overload its hosting.
If you quote an explanation, identify the source and preserve the surrounding assumptions. Do not present this website as an official HMRC service or misrepresent an estimate as professional approval.
4. Content and external material
Third-party names and trade marks belong to their respective owners. Their mention does not imply endorsement. Linked government material remains subject to the terms stated by its publisher. Original site content is not offered with a blanket licence to republish the entire website.
External links are provided to help you verify information. The operator does not control another website’s content, availability or privacy practices.
5. Availability and liability
Access is provided without a promise of uninterrupted availability or error-free results. Features and content may be corrected, changed or withdrawn. Keep your own copy of any result you need; saved comparisons are temporary.
Nothing in these terms excludes or limits liability where doing so would be unlawful, including liability for fraud or fraudulent misrepresentation, or death or personal injury caused by negligence. Nothing removes mandatory consumer protections. The legal effect of any limitation depends on the applicable law and circumstances.
6. Updates and questions
Changes apply to the version published on this page. The Contact page explains the current contact status. No particular court jurisdiction is specified while the operator’s location and legal identity remain unconfirmed.
