Diligens

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.

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.

A 2-Layer Defence

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.

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.
