Accounting software for contractors: the CIS invoice, on the worked example
£480

Both worksheets on this site compute on the page, free, with no account and no trial clock. The free version is the whole calculation; the paid plan is about keeping it: every invoice with its deduction, every deduction statement matched to a payment, every expense with its receipt, the year's totals as they build, and an export the accountant can open.

Every figure on this page is computed from the inputs entered, by the method stated below it. The two statutory rates the worksheets name, the CIS deduction rate for your status and the UK standard rate of VAT, are read from GOV.UK on the date shown and entered by you; Subbielane publishes no other rate, no allowable-expense rule and no tax computation. The defaults are a worked example to replace with your own figures.
