IR35 (Off Payroll Working Regulations)

From April 2020 the Off Payroll Working Regulations will come in to force for private companies, where previously the regulation only applied to public bodies.

The Off Payroll Working Regulations, commonly referred to as IR35, relates to workers operating though a Personal Service Company (PSC). A personal service company is broadly a company where the worker provides personal services to an end user through that company. The definition is quite wide and can include businesses which are more than a ‘one-man band’ operation.

The introduction of these regulations transfers the responsibility of the determination of ‘inside’ or ‘outside’ of IR35 to whomever pays the PSC, previously the PSC was legally required to determine that if it was ‘inside’ or ‘outside’ of IR35, although in many cases the PSC would ignore the requirement to make this ‘self-assessment’

If the worker is ‘inside’ IR35 the tax and NIC must be deducted from payments before they are made to the PSC, the tax and NIC is paid over to HMRC and then the PSC claims credit for the payments against its tax liabilities.

So who is the payer?

In broad terms anyone who pays for services or receives services from a PSC are categorised as within the scope of the scheme for IR35 purposes, in the following example all of the people in the chain would need to take some action with regard to IR35:

What do I need to do if I pay or I am in the payment chain for a PSC?

There are slightly differing requirements depending on whether you are an end user or an intermediary, common factors are:

  • You must have a system in place to identify and monitor PSC you pay either directly or via an intermediary
  • There must be an assessment process to decide if the PSC is inside or outside of IR35
  • Once the assessment is completed then it is a requirement that a Status Decision Statement (SDS) is issued to the PSC and any intermediary setting out the decision
  • If the PSC is inside IR35 then Tax and NIC must be deducted at the rates specified in the regulations and the Tax & NIC paid over to HMRC
  • The PSC may appeal against the process and then you have 45 days to deal with the appeal and provide reasons for upholding or altering your decision
  • Further monitoring must take place to check if there have been any changes in terms or conditions that move PSC either inside or outside of IR35

It follows that there needs to be more than a one-off exercise, but new starters need to be checked and a process of checking existing workers needs to take place on a regular or risk assessed basis.
