Common Questions

The Finance Act 2024 introduces new anti-fraud measures from April 2026 that allow HMRC to immediately remove Gross Payment Status (GPS) from businesses connected to fraudulent tax evasion—even if you weren't directly involved. If you engage subcontractors who are later found to be part of fraud networks, your GPS could be at risk. Our CIS Compliance Suite helps you identify potential risks in your subcontractor chain before this legislation takes effect.
Most accounting software focuses on bookkeeping and compliance filing—they're "detective" tools that record what's happened. Tax Radar is "preventative"—we identify risks before they become problems. Our software is built specifically to tackle HMRC compliance challenges, with risk models informed by real experience defending tax enquiries and investigating fraud.
Yes. Our bespoke development track is designed for organisations with specific compliance challenges that off-the-shelf software doesn't address. We've built custom employment status questionnaires, sector-specific risk analysis tools, and integrated solutions that work with existing systems. Contact us to discuss your requirements.
Our founding team includes former HMRC investigators and practising tax advisers who maintain active connections to the tax profession. We continuously monitor HMRC guidance, parliamentary committee reports, and regulatory announcements. When relevant changes occur, we update our risk models and notify affected clients.
Our current focus is on the construction sector, given the significant CIS compliance challenges and upcoming April 2026 legislation. We also serve professional services firms, recruitment agencies, and any organisation with complex contractor arrangements. Our bespoke development capability means we can adapt our solutions to virtually any sector.
