What is the 2 year rule for contractors?

The "2-year contractor rule" isn't a single law but refers to different concepts, primarily the UK's HMRC 24-month rule limiting tax relief on travel/subsistence for contractors at a single temporary workplace, and broader U.S. discussions about independent contractor classification, where long-term relationships (often nearing two years) signal employee status under Department of Labor (DOL) rules. In the UK, exceeding 24 months at one site (or 40% of time there) makes it a permanent workplace, ending expense claims. In the U.S., ongoing 2-year engagements raise red flags for misclassification, pushing the DOL to use various tests (like the current "economic reality" test) to determine if a worker is truly independent or an employee.
