How to invoice under CIS as a subcontractor

Under the Construction Industry Scheme the contractor takes tax off your labour before they pay you. Get the invoice right and the numbers match their statement.

What gets deducted

Your statusDeduction from labour
Registered with CIS20%
Not registered30%
Gross payment statusNone - paid in full

The deduction comes off the labour part only, not off materials you bought for the job. It counts as tax you have already paid, and you claim it back against your tax bill on your return.

What to show on the invoice

  • Your name and UTR, and the contractor's name
  • Invoice number, date and the job address
  • Labour and materials as two separate amounts - this matters, because only labour is deducted
  • VAT, if you are VAT registered (see below)
  • The total before the deduction and the amount you expect to receive after it

VAT and the reverse charge

If you are VAT registered and supply most construction work to another VAT-registered contractor, the domestic reverse charge usually applies: you do not charge VAT, the contractor accounts for it. The invoice then says so. The rules have exceptions, so check with your accountant or HMRC before your first one.

Keep the contractor's statements

Each month the contractor should give you a payment and deduction statement. Keep every one and match it against your invoices. If a deduction is missing from the statement, ask for it to be corrected - HMRC will only credit what the contractor reported.

Questions

Do I put the CIS deduction on my invoice?

Show labour and materials separately and the total. Many subcontractors also add the expected deduction so the net amount is clear. The contractor makes the actual deduction when they pay you.

Is the deduction taken from VAT too?

No. It is taken from the labour amount excluding VAT.

Can I get the deducted tax back?

Yes. It is set against your income tax and National Insurance on your self assessment, and any excess is repaid.
