This calculator is designed to assist UK-based contractors operating limited businesses in optimising their take-home profit through tax efficiency. Please note that the calculator currently accommodates a single employee and utilises a fixed NIC rate for the entire year. Be aware that this may not provide pinpoint accuracy if there are changes to NIC rates throughout the year.

Disclaimer: I am not a certified accountant; the calculator relies on information from the gov.uk website. Please reach out if you identify any issues.
