Calculation disclaimer
Understand the scope of the tools and when to seek further advice.
Use the breakdown, check the assumptions
LedgerKit provides estimates based on the information entered and configured rates. Results do not constitute accounting, tax or legal advice. Check current official guidance or consult a qualified professional before acting.
What the tools do not determine
LedgerKit does not determine tax status, VAT treatment, CIS verification, travel eligibility, entitlement to relief or legal entitlement to interest. It calculates the method you select; your circumstances may require a different approach.
Rates and rounding
Changeable rates are maintained centrally and shown with a tax year or checked date. Money is calculated with decimal arithmetic and displayed to the nearest penny. Rate changes and rounding rules for particular accounting processes may affect real-world treatment.
No government endorsement
LedgerKit is an independent UK business calculator website. It is not affiliated with or endorsed by HMRC or GOV.UK, and makes no claim of professional accreditation or regulatory authorisation.
