Tackling fraud in the Construction Industry Scheme (CIS) was one of the measures addressed in the recent Budget. The changes are intended to allow faster intervention where fraud is suspected, while also simplifying certain administrative aspects of the CIS.

From 6 April 2026, HMRC will be able to act immediately where a business makes or receives a payment that it knew, or ought to have known, was connected to fraud. In these cases, HMRC will have the authority to withdraw Gross Payment Status (GPS) straight away, assess the business for any related tax loss and impose penalties of up to 30%. Penalties may apply to the business itself or, in some circumstances, to its officers. Where GPS status is removed due to fraud or serious non-compliance, the business will also be prevented from reapplying for five years, a significant increase from the current one-year restriction.

The government also announced plans to simplify the operation of the CIS. Planned changes include exempting payments made to local authorities and certain public bodies from the scheme and reinstating the requirement for contractors to submit nil returns. These measures are expected to take effect from 6 April 2026, following a period of technical consultation.

The CIS applies special tax and National Insurance rules to construction businesses, with contractors generally required to deduct tax from payments made to subcontractors. Deduction rates depend on whether the subcontractor is registered and whether they hold GPS, which allows payment without deductions.
