Changes to the off-payroll working rules came into effect from 6 April 2021. Find out how the new rules apply to clients.

What has changed

From 6 April 2021 the:

  • rules for engaging individuals through personal service companies or other intermediaries changed
  • responsibility for working out if the off-payroll working rules (IR35) apply moved to the organisation receiving an individual’s services

You should make sure you understand:

  • the impact of the changes on your organisation
  • actions you might need to take

Understanding the new rules

You should check what HMRC support is available to help you understand the rules. Finance, HR and recruiting managers will also need to understand the changes. Find more technical guidance in the Employment Status Manual.

Steps you may need to take

1. Look at your current workforce

This includes those engaged through employment agencies.

  1. Identify individuals who are supplying their services through their own limited company (sometimes known as a personal service company) or other intermediary.

  2. Put in place processes to identify future individuals who work in this way.

2. Talk to individuals and agencies you engage with

  1. You may need information from them on some engagements.

  2. Share the contractor factsheet to help your contractors understand how the changes may affect them.

3. Determine if the off-payroll working rules apply

  1. Check if the rules apply for any contracts that will extend beyond, or start on or after 6 April 2021.

  2. Decide who in your organisation should make an employment determination.

  3. You can use HMRC’s Check Employment Status for Tax (CEST) service to make determinations.

  4. Look at escalations for difficult cases.

  5. Make a status determination.

4. After you’ve determined if the rules apply

  1. You’ll need to tell the contractor (and any agency you engage with) the outcome.

  2. Use a Status Determination Statement (SDS) to tell them.

5. Who will operate PAYE

  1. Consider if you or an agency will have to operate PAYE.

  2. If you’ll need to operate PAYE, put in place processes to make sure the correct Income Tax and employee National Insurance contributions are deducted for engagements inside the rules from 6 April 2021. You will also be responsible for paying employer National Insurance contributions and Apprenticeship Levy, if applicable.

6. Dealing with disagreements

You’ll need to set up a process to deal with any disagreements about the employment status determination. This is a legal requirement.

7. Keep records

You’ll need to make sure you maintain a robust audit trail. It is a legal requirement to keep records.

8. Test your processes

You’ll need to test your processes, systems and controls to make sure they work.

9. Changing working practices and contracts

You should follow the processes you’ve set up to revisit status decisions and make new ones if you:

  • change working practices
  • change contractual arrangements
  • renew contracts
  • create new contracts
