OPEN CIS CALCULATORWhat CIS rates are used?
HMRC uses 20% for registered subcontractors who can be verified, 30% where the subcontractor cannot be verified, and 0% for gross payment status. The contractor verifies the subcontractor and applies the rate HMRC gives them.
Materials and the CIS deduction
CIS is not simply a percentage of the invoice total. VAT and qualifying direct material costs are removed before the deduction is calculated. Only material costs the subcontractor directly paid for qualify.
CIS is an advance payment
A CIS deduction is an advance payment towards tax and National Insurance, not the final tax bill. Contractors must provide payment and deduction statements when deductions are made.
