What is the Construction Industry Scheme

What is the Construction Industry Scheme (CIS)?

The Construction Industry Scheme (CIS) is an HMRC tax scheme that applies to businesses in the construction sector. It requires contractors to deduct tax from subcontractors’ payments and send it to HMRC. This acts as an advance payment towards the subcontractor’s tax and National Insurance.

R

If a subcontractor is registered for Gross Payment Status, they receive full payments with no deductions, but must still pay tax at the end of the financial year.

R

If not registered, contractors must deduct 20% (or 30% for unregistered subcontractors) from payments.

Under HMRC’s CIS rules, contractors must submit monthly CIS returns to avoid penalties.
