Penalty Watch Digest

Each month HMRC names the businesses and individuals it has penalised for deliberate tax defaults. The Digest turns that list into clear lessons for directors – how defaults happen, how HMRC finds them, what the penalty rate tells you and how to stay off the list.

This month at a glance

  1. The five largest cases account for £24,338,898 of tax, 45% of the list.
  2. Payroll, staffing and business-support companies make up only 7 cases but £20,684,169 of tax (38%), the largest share of any sector. Large payroll and umbrella-type defaults like these are a known HMRC risk area for labour supply chains.
  3. Takeaways, restaurants and pubs are the most common sector, with 30 cases (£4,061,190 of tax). Most are mid-sized cases spanning several years, the pattern usually seen with suppressed sales.
  4. 42 cases (nearly all individuals) default over whole tax years, pointing to Income Tax. Trades include builders, landlords, carpenters, drivers and a doctor.
  5. 49 cases (36%) are listed as "formerly of" their address, so the business has moved or stopped trading.
  6. 31 cases were charged above 70% of the tax, which means deliberate and concealed behaviour. 6 were charged the full 100% with no reduction, and 1 above 100%.

Every case, with a full case card and penalty analysis, is in the PDF. Names are not shown on this page. The PDF report lists each case by name, exactly as HMRC published it; HMRC removes names one year after publication.

A director's checklist

  • Record every sale – cash, card and online – and never delete or alter till or EPOS records.
  • Reconcile card, platform, marketplace and bank income with your records and VAT returns every quarter.
  • Register for VAT, PAYE and Self Assessment on time, and file every return even when you cannot pay.
  • Pay over the PAYE, National Insurance and VAT you collect – it is not working capital.
  • Check suppliers and labour providers before you use them, and keep checking.
  • Keep evidence for every expense and any relief or repayment you claim.
  • If something has been missed, take advice and tell HMRC before it asks – an unprompted disclosure brings far lower penalties.
  • Directors can be made personally liable for their company's deliberate errors.

About the list

Who is named

HMRC publishes names under section 94 of the Finance Act 2009 where penalties have been charged for deliberate inaccuracies or failures and the tax is over the publication threshold, unless the maximum reduction for disclosure was given. Each name stays on the list for one year.
