Work out how much CIS a contractor will deduct from a subcontractor payment, and what you'll actually receive.
CIS deduction (20%)
£200.00
Net payment received
£1,000.00
CIS is deducted only from the labour element of a payment, not materials. Contractors deduct 20% for subcontractors registered with HMRC under CIS, or 30% for those who aren't registered. The deduction counts as an advance payment towards your Income Tax and National Insurance.
