A hidden tax liability may already be building in your contractor workforce.

Joint & Several Liability (JSL) for incorrect or unpaid PAYE and National Insurance deductions by Umbrella companies comes into force on 6th April 2026.

This means that if your organisation utilises Contractors who are paid by Umbrella companies, from 6th April 2026, you could be liable for outstanding payments if the Umbrella companies fail to deduct or pay the correct amounts owed. Find out more about this here.

Whilst it doesn’t come into force until 6th April, you could bear the risk for any time worked in previous months but paid on or after that date.

That is why early assessment and remediation are essential to avoid last-minute disruption and ensure contractors are paid correctly and compliantly.

To enable you to get a head start on your due diligence and risk mitigation, we are now offering a free Umbrella PAYE contractor supply chain risk assessment.

This is a short, structured review to help organisations to understand whether contractors engaged via umbrella companies could expose the business to PAYE and National Insurance risk.
