About CIS Deductions

Under the Construction Industry Scheme, contractors must deduct tax from payments to subcontractors and pass it to HMRC. Registered subcontractors have 20% deducted, while unregistered subcontractors have 30% deducted. The deductions count towards the subcontractor's tax and National Insurance.
