Root Cause

IR35 (Intermediaries Legislation) applies when a contractor would be an employee if directly hired; using a Personal Service Company (PSC) does not exempt the contractor from deemed employment tax and NI; HMRC determines status based on working practices, not corporate structure.

IR35（中介机构立法）适用于如果直接雇佣则承包商将成为雇员的情况；使用个人服务公司（PSC）并不能免除承包商的视同雇佣税和国民保险；HMRC根据工作实践而非公司结构确定身份。

Workarounds

  1. 85% success Conduct an IR35 status determination using HMRC's Check Employment Status for Tax (CEST) tool: https://www.gov.uk/guidance/check-employment-status-for-tax. If inside IR35, operate payroll via the agency or umbrella company.

  2. 75% success Restructure the contract to include genuine substitution clause, no mutuality of obligation, and no control over how/when work is done. Example: 'The Contractor may provide a substitute at their own expense, subject to reasonable client approval.'

Dead Ends

Common approaches that don't work:

  1. Using a generic contract template from an online source without an IR35-specific review 80% fail

    HMRC looks at actual working conditions (control, substitution, mutuality of obligation), not just contract wording; a standard template often fails the status determination test.

  2. Setting up a limited company but still working exclusively for one client with office hours and line management 90% fail

    This creates an employment-like relationship; HMRC will deem the contract inside IR35 regardless of corporate structure.
