Commonly Asked Question: what is Construction Industry Scheme (CIS)?
How to apply and who should apply for CIS
Under the Construction Industry Scheme (CIS), contractors deduct money from a subcontractor’s payments and pass it to HM Revenue and Customs (HMRC).
The deductions count as advance payments towards the subcontractor’s tax and National Insurance.
Contractors must register for the scheme. Subcontractors do not have to register, but deductions are taken from their payments at a higher rate if they’re not registered.
Who counts as a contractor or subcontractor
Register as a contractor if either:
you pay subcontractors for construction work
your business does not do construction work but you have spent more than £3 million on construction in the 12 months since you made your first payment
Register as a subcontractor if you do construction work for a contractor.
To register as a contractor you need to follow the process for setting up as a new employer at : Register as an employer - GOV.UK (www.gov.uk)
To register as a subcontractor you need to follow steps provided on GOV website at : What you must do as a Construction Industry Scheme (CIS) subcontractor: How to register - GOV.UK (www.gov.uk)
