Formal Neutral
What it really means
The name of UK tax rules about contractors who work through their own company. You will hear "inside IR35" (taxed like an employee) and "outside IR35" in contract job adverts. The rules are complex — read the official guidance on GOV.UK before signing anything.
Chinese explanation
英国一套关于通过自有公司接活的合同工的税务规则的名称。合同岗广告里常见"inside IR35"（按雇员方式纳税）和"outside IR35"。规则复杂——签约前请先阅读GOV.UK的官方指引。
Example conversation
A: This contract role says inside IR35.
B: That means you're taxed like an employee — check what that does to the day rate.
A：这个合同岗写着inside IR35。
B：那就是按雇员方式扣税——算算日薪实际到手还剩多少。
