HMRC is escalating its fight against avoidance in July 2025. The pressure falls squarely on tax avoidance in the construction management sector. Draft rules target promoters, with universal stop notices and tougher sanctions. AI tools and larger compliance teams raise the chance of checks. CIS, IR35, and VAT processes face closer review. This article outlines the changes, highlights risk hotspots, and sets out practical steps to stay compliant. Apex Accountants provides clear guidance tailored to construction managers.
HM Revenue & Customs (HMRC) is tightening its grip on tax avoidance. On 21 July 2025—the UK’s “Legislation Day”—the government released draft legislation targeting promoters of marketed tax‑avoidance schemes. The proposals would criminalise failing to notify HMRC about such arrangements and introduce universal stop notices and promoter action notices to prevent marketing of these schemes. HMRC’s Transformation Roadmap emphasises closing the tax gap with technology and artificial intelligence (AI), and the authority has already confirmed it uses AI to monitor data and detect unusual patterns.
HMRC is increasing capacity with £1.6 billion. This will fund 5,000 extra compliance officers and 1,800 debt-management officers. The staffing increase represents a 10% uplift. AI and data analytics will help flag suspicious patterns. Whistleblower incentives will encourage reporting of avoidance schemes. For construction management companies, these changes signal a tougher compliance environment.
Construction projects often involve multiple subcontractors, temporary workers, and complex supply chains. This complexity makes the sector attractive to promoters of aggressive tax schemes—such as misclassified off‑payroll arrangements or artificial employer structures. HMRC’s expansion of compliance teams means more scrutiny. Universal stop notices could ban entire categories of schemes, while promotion action notices may require banks, agencies, and advertisers to stop servicing promoters. Phoenix schemes that relaunch under new names will no longer escape attention. Therefore, construction managers must ensure their tax planning is robust, transparent, and defensible.
The July 2025 announcements comprise several measures designed to dismantle tax‑avoidance schemes and empower HMRC:
HMRC maintains and regularly updates a tax avoidance list. This public list names schemes and promoters that the tax authority believes to be non-compliant. Being associated with anything on this list can damage a company’s reputation and invite detailed enquiries.
For construction management companies, it is important to check the HMRC tax avoidance list before engaging with advisers or intermediaries. Working with a supplier, umbrella company, or payroll agency associated with schemes on the list could expose your business to penalties. Using the list as a reference point when conducting due diligence helps construction managers steer clear of high-risk arrangements and maintain transparency in their tax affairs.
A common question is: are tax avoidance schemes legal? Technically, many marketed schemes operate within the letter of the law. However, HMRC challenges such arrangements if they exploit loopholes or lack genuine commercial substance. While tax avoidance is different from tax evasion—which is outright illegal—the line is thin, and the risks are significant.
Construction managers who participate in schemes later deemed abusive may face backdated tax bills, penalties and interest. HMRC’s July 2025 crackdown demonstrates that legality is not a safeguard; even if a scheme appears lawful, it can still be investigated and shut down. The safest approach is to rely on genuine tax planning strategies, supported by professional advice, rather than schemes designed to artificially reduce liabilities.
