You should register for the Construction Industry Scheme (CIS) if you work for a contractor and you’re one of the following:
- a sole trader
- the owner of a limited company
- a partner in a partnership or trust
Under CIS, a contractor must deduct 20% from your payments and pass it to HM Revenue and Customs (HMRC).
These deductions count as advance payments towards your tax and National Insurance bill.
If you do not register for the scheme, contractors must deduct 30% from your payments instead.
If you do not want deductions made
If you do not want deductions to be made in advance by contractors, you can apply for ‘gross payment status’. You can do this when you register for the Construction Industry Scheme (CIS).
You do not need to register for CIS if you’re an employee. Check your employment status if you’re not sure.
