What is IR35?
IR35 is a legislation introduced in 2000 that prevents individuals from setting up as a company to avoid tax and National Insurance contributions. IR35 is designed to ensure that the contractors working via limited company are working the same as employees and hence must pay the same tax. Earlier, the employment status was determined by the contractors and not the hiring party.
The new reform says that the private sector will be responsible for determining the employment status of the Personal Service Company workers they engage with, from 6th April 2020. With the clock ticking for April 2020, it is essential that the private-sector firms realize that the IR35 reform can be managed and they should start preparing for it immediately.
The workers who fall within the IR35 legislation will require to let the PAYE and National Insurance Contributions be deducted from their Income at source. The agency or the end client will be responsible for deducting the relevant tax and NIC on behalf of the worker, prior to paying the PSC’s fees. The rules are similar to that of ‘off-payroll workers in the public sector’ which came into force from 2017.
The changes mean that the party (client or recruiter) is responsible for paying the contractor and he is liable if HMRC decides the contractor’s IR35 status has been wrongly determined. So it is important to make the IR35 status decisions accurately.

The reform was introduced in the Autumn Statement 2018 budget. The hiring party has to provide ‘status determination certificate’ to the contractor as well as the agency. The certificate must include the employment status decision and the reason behind this decision. The off-payroll working rules require cooperation between the agency and the end user in determining and applying the employment status of the worker.
