GPS revocation risk under April 2026 rules
From 6 April 2026, HMRC can revoke GPS immediately and without advance notice if a contractor is found to have connections with fraud in the supply chain, on a 'knew or should have known' standard. Paying a connected party you knew, or had reason to know, was deliberately breaking CIS rules now carries a penalty of 20% of the payment under Finance Act 2026. Demolition contractors working with multiple subcontractors carry real exposure here.
