Accounting for contractors under CIS: the invoice worked, the year kept, the accountant handed figures
Accounting for contractors is mostly one deduction and one year: the CIS deduction the main contractor takes off every invoice, and the twelve months of income, expenses and deduction statements the accountant needs in April.

Worksheets
The worksheets, free and open
Subbielane works both on the page from your own figures: the invoice from labour, materials, your deduction rate and the VAT you charge, so the invoice, the deduction and the amount that lands in the bank agree; and the year from a day rate, days worked, expenses and the CIS already withheld, so profit before tax and what is still to set aside are numbers rather than a worry.
Free, no account. Pro keeps every invoice, statement, payment and expense against the client and the tax year. Nothing here files a return or gives tax advice.

The CIS deduction worked before the invoice goes out
£2,400 of labour and £600 of materials at a 20% deduction rate is a £480 deduction, a £3,000 invoice and £2,520 into the bank, worked on the page so the invoice, the deduction statement and the payment agree before anyone rings to ask.

Profit before tax and the set-aside, as the year builds
£250 a day for 220 days is £55,000, £11,000 of it withheld under CIS before it reaches you; less £6,000 of expenses it is £49,000 of profit, and a 25% set-aside is £12,250, of which the contractors already hold £11,000. The set-aside is yours; the arithmetic is the worksheet's.
-
Every invoice, statement and expense filed to the tax year
Invoices with their deductions, deduction statements matched to payments, and expenses with receipts file themselves against the client and the tax year, so April is an export rather than a shoebox. Everything exports.
