The scheme, handled where the payroll happens
Verifying a subcontractor, working out what is liable to deduction, filing by the 19th and getting statements out are one job, not four. They belong in one place.
Verified with HMRC before you pay them
Send a verification and get back the treatment that applies: gross, net at 20 per cent, or unmatched at 30 per cent when HMRC cannot find the subcontractor. The rate follows through to the payment automatically, so nobody is deducted at the wrong rate on a guess.
Materials come off before the deduction
The deduction applies to labour, not to the materials a subcontractor supplies. Record the cost of materials against the payment and the amount liable is worked out on what remains, which is the rule most often got wrong by hand.
CIS300 filed, statements sent
The monthly return is built from the payments you have already made, filed before the 19th, and each subcontractor gets the deduction statement they are entitled to, as a PDF or straight to their inbox.
Subcontractors are not employees, and are not treated as such
CIS subcontractors sit outside auto-enrolment, hold no benefits in kind, and their payments never reach an FPS. Employed staff run in the same payrun, taxed and reported the way employees must be.
The whole scheme, and the payroll around it
From one director paying themselves to a site with forty subcontractors on it.
Subcontractor verification
Verify or match against HMRC, singly or in a batch, and follow each submission from pending to matched. The tax treatment that comes back drives the deduction from then on.
CIS300 monthly returns
The return is assembled from the month’s payments, editable until it is filed, and locked once HMRC has accepted it.
Deduction statements
The statement each subcontractor is owed: gross, materials, amount liable, amount deducted. Downloadable as a PDF or emailed to them directly.
CIS suffered, reclaimed
A limited company that has had CIS deducted from it carries that on the EPS and the P30, so what you owe HMRC each month is what you actually owe.
PAYE staff and directors
Employed staff, workers inside IR35 and director salaries with the annual earnings period, all in the same payrun as the subcontractors.
API for volume users
Verifications, returns and statements are all available over the REST API, for firms running this at scale inside their own systems.
CIS and contractor payroll, answered
Yes. The return is built from the payments recorded in the month, submitted to HMRC before the 19th, and tracked through to acceptance. It can be corrected right up until it is filed, and is locked once HMRC has accepted it.
