Subcontractors

Definition

Subcontractors are third parties a main contractor engages to carry out part of its contractual obligations, while remaining itself liable to the principal for the full performance. Contracts often regulate whether subcontracting is allowed, whether prior consent is needed, and require key terms to be flowed down. In labour and tax matters Dutch chain liability rules can make the principal co-liable for wages and payroll taxes unpaid down the chain.

Example

A general contractor hires an electrical subcontractor; the construction agreement requires the same safety and insurance terms to be flowed down to that subcontractor.

Why this is a business risk

A contractor who subcontracts without the principal's required consent, or without flowing down key obligations, risks being in breach of the main contract. Dutch chain liability rules mean the principal can be held liable for unpaid wages and payroll taxes owed by a subcontractor further down the chain, even if the main contractor appeared solvent. If a subcontractor underperforms, the main contractor bears the full risk to the principal while having limited remedies against a poorly documented subcontract.

How to manage it

• Check the main contract for any consent requirement before engaging a subcontractor; seek written approval if required.
• Flow down all material obligations from the main contract to each subcontract, including safety, insurance, confidentiality and quality standards.
• Verify that each subcontractor pays wages and taxes on time to limit your chain liability exposure; consider using a g-rekening arrangement.
• Keep a register of all active subcontractors linked to the relevant main contract so you have a clear picture of the supply chain at any moment.
