Navigating the UK Construction Industry Scheme (CIS)

The Construction Industry Scheme (CIS) is a set of tax and National Insurance rules specifically crafted for individuals and businesses operating in the UK construction industry. Whether you’re a ‘contractor’ or a ‘subcontractor’, understanding CIS can ensure you manage your tax obligations effectively.

What is the Construction Industry Scheme (CIS)?

The CIS is a tax initiative by the UK government that mandates contractors to deduct a portion of payments made to subcontractors and transfer this amount directly to Her Majesty’s Revenue and Customs (HMRC). These deductions are essentially advance payments towards the subcontractor’s tax and National Insurance liabilities.

Who Does the Construction Industry Scheme Apply to?

The CIS applies to contractors who pay subcontractors for construction work or businesses that have spent more than £3 million on construction in the 12 months since their first payment. While subcontractors are not obligated to register for the CIS, they will see a 30% deduction from their payments if they remain unregistered. However, if a subcontractor registers under the CIS, this deduction is reduced to 20%. Alternatively, subcontractors can apply for gross payment status.

What are the Reporting Obligations under C.I.S.?

Under the CIS, contractors are required to submit monthly returns online, which detail payments made to subcontractors for each tax month (from the 6th of one month to the 5th of the next). The deadline for submission is 14 days after the end of the tax month. If a contractor doesn’t make any payments to subcontractors in a particular month, they must submit a ‘CIS nil return’ or notify HMRC that no return is due.

Changes in VAT Rules under the c.i.s.

As of 1 March 2021, the VAT rules for building contractors and subcontractors have changed. For certain specified supplies, subcontractors no longer add VAT to their services for most building customers. Instead, contractors are required to pay the output VAT on behalf of their registered subcontractor suppliers – a mechanism known as the Domestic Reverse Charge. Contractors can then reclaim the output tax paid as input VAT, as per the standard rules.
