Extension of the off-payroll (IR35) rules into the Private Sector 2021

Important Changes to Legislation Effective 6th April 2021


What is Happening and When?

 What: The Government is extending the off-payroll rules, which have applied in the public sector since April 2017, into the private sector. The new rules will apply to work done by contractors working through intermediaries such as personal service companies ( PSC) . Importantly, the tests for IR35 status are not changing but the responsibilities for making the IR35 status decision and related deductions are.

When: The new rules will apply to all payments made to personal service companies for services provided on or after 6 April 2021.

What’s the difference? From 6 April 2021, the client, and not the contractor, will be responsible for assessing IR35 status of the contractor. For inside IR35 assignments, the fee-payer will have to make tax and national insurance deductions before paying the personal service company.

The off-payroll rules (IR35) which currently apply in the public sector will be extended into the private sector from 6 April 2021, albeit with some changes. This means that a client will need to know how a contractor is engaged e.g. whether on a PAYE basis by an agency, or whether paid via an intermediary such as a personal services company or an umbrella company (the rules will apply even where clients engage contractors directly rather than through an agency). The key issue is that where the off-payroll rules apply, the client will be responsible for assessing the contractor’s status for tax purposes. So which clients will the off-payroll rules apply to and what will the client need to do? ... please click here to view our factsheet, produced by the REC,  with more details.
