Does InvoiceAdept file CIS300 to HMRC?

No. InvoiceAdept creates CIS invoices and exportable records. You still file CIS300 in HMRC’s own service.

Is the CIS invoice generator free?

CIS invoicing is on Pro+ at £12.99 a month. Free is 5 invoices a month with no CIS.

CIS invoice template UK

A Construction Industry Scheme invoice has to split labour and materials, show the deduction, and leave the contractor in no doubt what to pay. Create one in InvoiceAdept on Pro+ (£12.99/month). This is a digital record and export — InvoiceAdept does not file CIS300 to HMRC.

What a CIS invoice must show

Your name, address, and Unique Taxpayer Reference (UTR)
The contractor’s name and address
Invoice date and a unique invoice number
Labour amount (CIS applies) and materials amount (CIS does not)
CIS deduction rate — 20% verified, 30% unverified, or 0% gross status
Gross, deduction, and net payable, shown clearly
VAT treatment, including domestic reverse charge where it applies

How the generator works

1. Add the job. Labour on one line, materials on another. CIS applies to labour only.
2. Set the rate. 20% verified, 30% unverified, or 0% gross payment status. Store the UTR and verification number on the customer.
3. Send or export. PDF, email, or WhatsApp on Pro. Keep the monthly summary for the CIS300 you file yourself.

Domestic reverse charge

On many specified construction supplies between VAT-registered businesses, VAT is accounted for by the customer under the domestic reverse charge — you do not add VAT for the contractor to pay you. The invoice should still show the VAT rate that would have applied and state that the reverse charge applies. InvoiceAdept can mark a line as reverse charge so the PDF is clear. This is not a separate product URL; it is part of the same CIS invoice.

Reverse charge does not replace CIS. You can still deduct CIS on labour while the VAT is reverse-charged. If you are unsure whether a job is reverse charge, check HMRC's guidance or ask your accountant — InvoiceAdept does not decide your VAT status for you.
