On new-build and larger refurb work, plumbing and heating is routinely subcontracted for first fix pipework and boiler or cylinder installs, with subcontractors often gas-registered specialists paid per plot rather than by the hour. A busy heating contractor can have a dozen such subcontractors on the books, some registered gross, some net, some still unverified while their Gas Safe paperwork catches up. Each needs the right rate and the right statement, on time, every month.
Runs in your browser · your subcontractors’ data never reaches us
A gross-registered heating engineer and a newly onboarded, unverified one in the same upload each get the correct rate automatically from the status you set.
Where a subcontractor supplies the boiler, cylinder or pipework materials themselves, that cost is excluded from the taxable figure before the deduction is applied.
The same upload produces every subcontractor's statement and the totals for your monthly return, so the two always match.
No. We generate the CIS Payment and Deduction Statements and the CIS300 totals you need. You still send the statements to your subcontractors and file your return yourself, or hand the totals to your accountant.
Within 14 days of the end of the tax month the payment falls in. The CIS tax month runs 6th to 5th, not the calendar month, so a payment on 3 May belongs to the 6 April to 5 May tax month.
0% if the subcontractor is registered for gross payment, 20% if they're registered for net payment, 30% if they're not verified with HMRC. You tell us the status per subcontractor and we apply the right rate.
