The general information about IR35 and the changes coming with this legislation can be found in much more detail. I will focus on how it will affect ECAA Turkish Businessperson Visa Holders. In simple terms, IR35 means IT contractors who do not work on strictly project-based roles need to pay PAYE which is basically employee-income-tax. The problem starts here because Turkish Businessperson Visa holders cannot pay employee-income-tax (PAYE) as their visa would be on danger if they pay such a tax. This unintended outcome of the legislation does not just bring more tax burden to ECAA Visa holders, but simply rules out any chance to work in such positions.
