Clients
How do we help clients sleep easy in the face of IR35 compliance risk and complexity?
- We help you to keep acquiring and retaining top talent from the WHOLE TALENT pool.
- Our IR35 Status Assessment Tool page explains how we help you meet and even exceed regulatory, compliance and reasonable care obligations laid down by HMRC.
- We enable your hiring managers or compliance team to quickly and efficiently generate, issue, store and periodically review robust IR35 Status Determination Statements (SDS).
- Clients can play a fully active role or can ask agent or contractor to complete the assessment and simply send it to you for review, approval and SDS generation.
- We furnish contractors with a robust substitution capability in the event you both determine it’s warranted in the absence of your usual resource.
- We enable you to optionally help cement a legal right of substitution you may already have in contracts, with a Right of Substitution Declaration.
- Our Substitution page explains at the outset why the often misunderstood Right of Substitution is actually a benefit for clients.
- These FAQs also explain what you are and more importantly, are NOT signing up to.
- We can turn 'paper tiger' contract clauses into a fanged and clawed right of substitution and deter any dispute from HMRC.
