Protect your agency
From 6 April 2026, strict liability means you inherit the tax debt of every fraudulent entity in your supply chain, even if you didn't know they existed.
Tax software checks the payslip maths. Diligens checks the DNA of the company receiving your money. Catch burner entities and ghost workers before the money leaves your bank.
The 2026 Regulations Opened the Door. Organised Crime Walked Through It.
Your supply chain is being infiltrated by Trojan Horse shell companies — and your tax software can't see them.
Organised crime rings use Mini-Umbrella Company (MUC) schemes to fragment your workforce across hundreds of disposable shell entities. Each one is designed to steal funds and vanish before paying tax — leaving you with the bill under strict liability.
Your Potential Annual Liability Exposure
50 workers
£400K → £1.9M
500 workers
£4M → £19M
3,000 workers
£24M → £112M
Estimated annual PAYE + NIC exposure based on £16.50-£50/hour rates. Even 1% non-compliance represents significant risk.
Legitimate Umbrella
One verified entity, proper PAYE compliance, transparent tax payments
Hundreds of Shell Companies
Burner entities, ghost workers, identity hijacking, organised fraud
The April 2026 ticking clock
Due diligence alone no longer protects you. Under the new strict liability rules, if the entity receiving your money doesn't pay their tax, you inherit the entire debt. No excuses. No defences. The regulations make supply chain visibility legally mandatory.
You need to verify the identity of every entity before you pay them — not just check the paperwork after.
Tax Software Checks the Maths. Diligens Checks the Identity.
A fraudster can generate a perfect payslip to pass a tax audit — while using a 2-week-old shell company to steal the actual funds. Tax compliance platforms verify the maths. Diligens verifies the identity of the company receiving your money. Under strict liability, you need both.
Identity & Fraud Verification
Who is the company receiving your money? Is it a Trojan Horse PSC, a shell entity, or a ghost worker operation? We verify the DNA of the company before you pay.
Tax Verification & Certification
Are taxes calculated correctly? Disclosed via RTI? Actually paid to HMRC?
Complete Protection
Each layer catches what the other misses. Neither alone is enough under strict liability, but together, every gap is covered.
The Corporate DNA Checks That Catch Fraud Before You Pay
We don't analyse paperwork. We analyse the corporate anatomy of every entity in your payment run — the patterns that organised crime rings can't hide.
Director Velocity
Is the same person running hundreds of 'separate' umbrellas?
We flag individuals appointed to an impossible number of unrelated companies in short timeframes. If your umbrella's director also runs 200 other 'umbrellas', they're likely a 'mule' in a MUC network.
Clone Clusters
Are dozens of companies registered at the same residential address?
We detect mass registrations of unrelated entities sharing single office suites, P.O. boxes, or even garden sheds. Real example: 487 'umbrellas' registered to one flat. These 'industrial farms' are designed to fragment liability.
Phoenix Companies
Has this director run companies that folded owing tax before?
We trace directors' histories for patterns of companies being 'struck off' with unpaid debts, then the same person starting new ones. Average phoenix cycle: 18 months. They trade, accumulate tax debt, dissolve, repeat.
Offshore Control
Is a UK payroll company being run from overseas?
We detect UK-registered companies controlled by directors with no UK footprint — often in high-risk offshore hubs. Under JSL rules, if the offshore entity 'disappears', you're the nearest solvent UK entity HMRC can pursue.
Name Patterns
Does this company name look algorithmically generated?
Fraudsters use algorithms to mass-generate company names. We detect these patterns like random word combinations, typo-squatting of legitimate brands, and suspiciously similar naming across hundreds of registrations.
Address Anomalies
Is a payroll operation registered to a residential home?
Our geospatial engine flags industrial-scale payroll operations registered to semi-detached homes, flats, or farmhouses. Legitimate payroll providers don't run from spare bedrooms.
Shelf Companies
Is this a dormant company suddenly 'woken up' with new directors?
Old, dormant companies are purchased and 'reactivated' with fresh directors to feign maturity and stability. A company registered in 2015 that suddenly has new directors and starts processing payments in 2025 is a red flag.
Zombie Status
Is this company even legally allowed to trade?
You cannot legally pay a dissolved company, but it happens. We flag entities that are 'Dissolved', in 'Liquidation', or have zero active directors. If you're sending money to a zombie company, that's a serious compliance failure.
SIC Code Mismatch
Is a 'management consultancy' actually supplying labour?
Labour suppliers often hide behind vague SIC codes like '70229 - Management Consultancy' to avoid HMRC's targeted scrutiny. We cross-reference what they claim to do vs what they actually do.
Impossible Scale
Is a 14-day-old company invoicing for 40 active workers?
Ghost Worker detection: we flag mathematical anomalies that reveal burner entities on their first payroll run. A company incorporated two weeks ago cannot legitimately employ dozens of workers. When your weekly payroll file hits our Dropzone, we catch these instantly.
Clean the Slate. Then Keep It Clean Every Tuesday.
From forensic onboarding to weekly pre-payment screening — a two-step defence against supply chain fraud.
Identify Your Blind Spots
Does your screening detect 'Nominee Velocity', where officers hold high volumes of appointments across unrelated sectors?
