The UK’s National Crime Agency magazine (SARS in Action Issue 31) published in April 2025, highlighted a growing financial crime about which accountants need to be aware.

Umbrella Company (MUC) Fraud is a type of organised labour fraud where a large, temporary workforce is disaggregated into multiple, small, limited companies (MUCs) by organised crime groups (OCGs).

We bring this to our reader’s attention, especially to the Money Laundering Reporting Officers (MLRO) out there, as criminals know no borders and such MUC fraud may be happening in Ireland right now.

It costs the UK Exchequer alone hundreds of millions of pounds every year. HMRC is aware that OCGs regularly target the temporary labour sector and have several ongoing investigations using a full range of civil and criminal powers, in parallel, to provide the most effective and immediate response.

The fraud is operated by an OCG that breaks down one temporary labour provider, low in the supply chain, into hundreds of MUCs allowing each to build up debts to the government and/or take advantage of Government incentives aimed at small businesses. Each MUC then dissolves.

The OCG often uses stolen or fraudulently purchased identities for the MUCs directorships, to avoid personal association, including foreign nationals. There is no standard model for MUC fraud. It is constantly evolving, as OCGs try to hide their fraudulent activities.

However, MUCs often only employ a few (mostly unaware) workers and there is always a promoter/umbrella-style business further upstream in the supply chain that organises the structure of the MUCs, which is sometimes known as an ‘outsourcing business’, with other linked, administration style businesses to support the operation.

Signs to watch for:

Some tell-tale signs to watch out for that may indicate the presence of a MUC:

  1. Large volumes of companies registered at the same address, often residential/non- business addresses.
  2. Periods of dormancy after bank account inception.
  3. Companies that hold the bank accounts lack an online presence.
  4. Few or no payments to HMRC.
  5. Receipts of large payments from recruitment agencies from the opening of the account, far in excess of the anticipated turnover or not consistent with the declared business type.
  6. Profits from the fraud are often extracted internationally by the OCGs, disguised as fees, admin expenses and other purchases, often through companies and bank accounts also based abroad.
  7. Links to/use of nonbank Payment Service Providers (NBPSPs) that use FinTech/Blockchain technology and Alternative Payment Systems (APS) to provide financial services without a traditional banking license.
