CISR15120 | The Scheme: payments: contractor deductions (for example, administration, PLI)
From HM Revenue & Customs · Construction Industry Scheme Reform Manual
On occasions, contractors may make deductions from payments due to subcontractors in respect of:
public liability insurance
CITB Levy (see CISR15110)
administrative charges.
Since CIS is tax machinery applied to payments made rather than payments due under a contract, CIS only applies to the payment actually made, net of these deductions. Payments in respect of those deductions should therefore be ignored when determining the ‘gross payment’ to be included in the monthly return.
