How to register
To register for the Construction Industry Scheme (CIS) you’ll need:
- your legal business name - you can also give a trading name if it’s different to your business name
- your National Insurance Number
- the unique taxpayer reference number (UTR) for your business
- your VAT registration number (if you’re VAT registered)
If you’re a subcontractor and a contractor (you pay subcontractors to do construction work), you’ll need to register for CIS as both.
Register as a sole trader
If you’re a sole trader and you already have a UTR you can register for CIS online by logging in with your Government Gateway ID.
You can apply for gross payment status at the same time.
If you don’t have a UTR, register as a new business for Self Assessment and choose ‘working as a subcontractor’ when prompted. You’ll be registered for Self Assessment and CIS at the same time.
You can also call the CIS helpline to register.
Register as another type of business
HMRC will register the partnership separately to your sole trader registration. They’ll need the partnership UTR and trading name.
You’re based abroad
You should still register for CIS if you’re a subcontractor based abroad but do construction work in the UK.
