Tax Guidance


What is CIS (Construction Industry Scheme)?

CIS is short for Construction Industry Scheme. It's HMRC's way of collecting income tax from people who operate within the construction industry e.g. builders and electricians.

It is a tax deduction scheme designed to deduct tax at source for work undertaken in the construction industry – an industry which has not been seen as compliant with tax rules. The contractor (see definitions ​below) is responsible for deducting a flat rate of tax from their subcontractors and passing this to HMRC. The subcontractor will then need to account for the deduction on their self assessment.
