Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how much revenue has accrued to the public purse from IR35 in each year since it was implemented.

The off-payroll working rules (IR35) have been in place for nearly 20 years. They are designed to ensure that individuals working like employees but through their own company pay broadly the same tax and National Insurance contributions (NICs) as other employees who are directly employed.

HMRC do not have an annual breakdown of revenue received from the application of the off-payroll working rules. The Government estimates that only one in ten personal services companies (PSCs) who should be operating the rules are doing so. This non-compliance is projected to increase from £700 million per year in 2017/18 to £1.3 billion per year in 2023/24.

HMRC have measured the impact of reforming the off-payroll rules in the public sector and estimate that the reform has already raised an additional £550 million in income tax and NICs in the first 12 months since it was introduced.
