What is a CIS Invoice?
The Construction Industry Scheme (CIS) is a UK tax framework that requires contractors to deduct tax from payments to subcontractors and submit those deductions to HMRC. A CIS-compliant invoice must include specific information to ensure proper tax treatment.
Our CIS invoice generator ensures your invoices meet all HMRC requirements, including separation of labour and materials, correct deduction rates (20% or 30%), and VAT handling.
