Subcontractors verified, deduction rates applied correctly, materials handled separately and monthly CIS returns kept to the 19th.
CIS is the Construction Industry Scheme. Under it, a contractor deducts money from a subcontractor's payments and passes it to HMRC as an advance payment towards that subcontractor's tax and National Insurance. We verify subcontractors, apply the correct rate, pay the net amount, and file the monthly return.
The rate is not a guess. HMRC verification tells you whether to pay gross, deduct at the standard registered rate or deduct at the higher unregistered rate. CIS deductions apply to the labour element, not qualifying materials directly paid for by the subcontractor, which is why the invoice split, evidence and records matter. CIS is also not an employment-status fix: it applies where the subcontractor is self-employed for the work in question and the payment falls within the scheme.

Construction contractors, developers, and recruitment agencies supplying construction labour where CIS may apply.
Businesses paying subcontractors for construction operations and needing verification, deductions, statements and returns handled properly.
Property and construction groups with multiple trades, sites and subcontractor payment patterns.
Agencies supplying construction labour where CIS may apply and agency-worker or status issues still need separate review.
CIS gets messy when site changes outrun the paperwork. A subcontractor changes status, materials are not evidenced, a labour-only payment is treated like a mixed invoice, or the return misses a tax month.
RPS keeps the process tight: verify, classify, calculate, statement, return, record. From groundworks to fit-out, brickwork to roofing, we run CIS across the full mix of trades on your books, so the people on your sites are paid the correct net amount and the figures behind every payment hold up.

CIS is the Construction Industry Scheme. Under it, a contractor deducts money from a subcontractor's payments and passes it to HMRC as an advance payment towards that subcontractor's tax and National Insurance. We support verification, apply the correct rate, pay the net amount, and support the monthly return.
The current safe rates are 20% for registered subcontractors, 30% for unregistered subcontractors and 0% where HMRC confirms gross payment status. HMRC verification determines the treatment to apply. Rates are current at time of writing and confirmed against HMRC at the point of running your scheme.
No. CIS deductions are calculated on the amount left after taking away qualifying materials and certain other allowable direct costs. The materials element needs evidence and should not be overstated, so subcontractors are not over-deducted.
The return for a tax month must reach HMRC within 14 days of the end of that tax month. In practice, payments made between the 6th of one month and the 5th of the next need to be reported by the 19th. We support the monthly return and produce a clean deduction statement for every subcontractor each month.
