When does IR35 generally apply?
It would apply if the contractor uses an intermediary to provide their services or labour and they would be deemed to be an employee or office holder for tax purposes if they were hired directly by the end user client rather than via the intermediary PSC. This would of course require an assessment of employment status for tax purposes.
Contractors who are not taxed in the UK and supply their services exclusively from outside of the UK are unaffected.
If IR35 applies, tax and NIC’s should be deducted under PAYE by the PSC. In reality this has not been happening so a major reform of the regime was due to be implemented in April 2020. The changes were postponed by one year and are due to take effect from 6 April 2021.
“Within IR35” means a contractor arrangement is caught by IR35 and the individual should be taxed as an employee.
“Outside IR35” means a contractor arrangement is not caught by IR35 and the contractor status is fine.
