IR35
IR35 (also known as the off-payroll working rules) affects whether contractors are treated as employees for tax purposes. If it applies, PAYE and National Insurance must be deducted. Getting it wrong can mean tax penalties, reputational damage, and employment disputes. We help you stay on the right side of the rules.
Status Determination Statements (SDSs)
We prepare defensible SDSs tailored to each contractor, using HMRC’s CEST tool, current case law and sector-specific guidance. We clearly document the reasoning and employment risks.
Consultancy agreements and statements of work
We draft and refine consultancy agreements, SoWs and schedules to reflect genuine self-employment, workable substitution, clear deliverables, compliant payment terms, and proportionate indemnities.
Contractor reviews and risk assessments
The audit of current arrangements, substitution and mutuality factors, highlights any IR35 exposure and provides practical next steps to reduce risk.
Off‑payroll policies
We advise on off‑payroll policies, workflows, clarifying roles, sign‑offs, evidence retention, monitoring, and escalation routes.
Challenges, tribunals, and contract disputes
We respond to SDS challenges, defend or pursue employment status claims, and manage related breach‑of‑contract disputes and settlement discussions.
Questions we’re often asked

A written status determination statement explaining the IR35 decision and supporting reasons.
No. It helps, but robust evidence, contracts and governance remain essential.
The fee-payer could owe tax, NICs, interest and penalties. There may also be reputational or legal fallout.
Yes. If they do, you must review the challenge and respond with your reasons.
