IR35 Services Agreement Template for England and Wales
IR35 (the off-payroll working rules) applies across England and Wales under Chapter 8 and Chapter 10 ITEPA 2003. Since April 2021, medium and large private-sector engagers must issue a Status Determination Statement (SDS) before engagement begins. A professionally drafted services agreement is the contractor's primary evidence of independence.
England and Wales-specific legal consideration
Chapter 10 ITEPA 2003 places the IR35 determination on the engager (not the PSC) for medium and large companies. The engager must issue a Status Determination Statement (SDS) and use reasonable care — failure to do so transfers the tax liability back to the engager.

Frequently asked questions
Is an AI-generated ir35 agreement valid and enforceable in England and Wales?
An AI-generated ir35 agreement is valid in England and Wales provided it satisfies the requirements of Law of England and Wales: offer, acceptance, consideration, and certainty of terms. Courts assess enforceability based on the substance of the agreement, not how it was drafted. Review any AI-generated contract before signing; for high-value or complex engagements, a qualified solicitor or lawyer in England and Wales can verify it reflects your specific situation.
What is the key legal consideration for a ir35 agreement in England and Wales?
Chapter 10 ITEPA 2003 places the IR35 determination on the engager (not the PSC) for medium and large companies. The engager must issue a Status Determination Statement (SDS) and use reasonable care — failure to do so transfers the tax liability back to the engager.
What are the three HMRC tests for IR35 determination?
HMRC applies three primary tests: (1) Substitution — does the contractor have a genuine, exercisable right to send a qualified substitute without the engager's veto? (2) Control — does the engager direct how, when, and where work is performed? (3) Mutuality of Obligation — must the engager offer work and the contractor accept it? Failing any test increases inside IR35 risk. A services agreement must address all three tests explicitly.
Can a services agreement guarantee an outside IR35 result in England and Wales?
No contract wording can guarantee an outside IR35 determination — HMRC looks at the substance of the working relationship, not just the contract terms. A services agreement supports an outside result when it accurately reflects genuine independence: real substitution rights, deliverables-based work, and no standing obligation to accept or offer assignments. If the contract asserts "outside IR35" but the contractor functions as an employee, HMRC can disregard the contract wording entirely.
