Most contractors prefer to work on contracts that are found to be outside of IR35, because it’s more tax efficient and therefore gives them a higher take-home pay. Until April 2021, the contractor is in charge of assessing their own IR35 status, based on a number of HMRC rules. However, from 1st April, that responsibility becomes the end hirer’s.
The rules are not changing, so in theory, if you are legitimately contracting off payroll through a Limited Company now, then you should be able to continue to do so post-April. However, our experience of the changes being implemented in the Public Sector suggest that some end hirers may take a more risk averse stance, deeming a larger proportion of contractors as inside IR35 as a result.
