If you’re a contractor, freelancer, or business hiring contractors in the UK, you’ve probably heard of IR35. But what exactly is it, and why does it matter?
In this guide, we’ll break down IR35 in plain English, explain how it affects you, and share practical steps to stay compliant and avoid unexpected tax bills.
What Is IR35?
IR35 is a set of tax rules introduced by HMRC to prevent individuals from avoiding taxes by working through an intermediary, like a Personal Service Company (PSC), while effectively operating as employees.
If you’re deemed to be “inside IR35,” it means you’re considered an employee for tax purposes, and you must pay Income Tax and National Insurance Contributions (NICs) similar to a regular employee. If you’re “outside IR35,” you’re considered self-employed and can operate under different tax rules.
Why IR35 Matters
Being inside or outside IR35 affects:
- Your take-home pay: Inside IR35, you’ll pay more in taxes and NICs.
- Your responsibilities: Inside IR35, the party paying you (client or agency) must deduct taxes before paying you.
- Your business model: It influences how you structure contracts and work with clients.
Who Determines IR35 Status?
The responsibility for determining your IR35 status depends on the size of your client:
- Public sector clients: The client determines your status.
- Medium or large private sector clients: The client determines your status.
- Small private sector clients: You, as the contractor, determine your status.
A company is considered “small” if it meets at least two of the following criteria:
- Annual turnover of £10.2 million or less.
- Balance sheet total of £5.1 million or less.
- 50 employees or fewer.
Key Factors in Determining IR35 Status
HMRC considers several factors to assess whether you’re inside or outside IR35:
1. Control
- Inside IR35: The client controls how, when, and where you work.
- Outside IR35: You have autonomy over your work schedule and methods.
2. Substitution
- Inside IR35: You’re required to do the work personally.
- Outside IR35: You can send someone else to do the work, and the client accepts this.
3. Mutuality of Obligation (MOO)
- Inside IR35: The client expects you to accept work, and you expect them to provide it.
- Outside IR35: There’s no obligation for ongoing work beyond the current contract.
4. Financial Risk
- Inside IR35: You have little to no financial risk; the client covers mistakes.
- Outside IR35: You bear the cost of rectifying errors and may invest in your own equipment.
5. Integration
- Inside IR35: You’re integrated into the client’s organization, attending staff meetings and using their equipment.
- Outside IR35: You operate independently, using your own tools and not being part of the client’s internal structure.
Status Determination Statement (SDS)
When a client assesses your IR35 status, they must provide a Status Determination Statement (SDS), explaining their decision. If you disagree with the SDS, you can challenge it, and the client must respond within 45 days.
Consequences of Being Inside IR35
If you’re inside IR35:
- The fee-payer (client or agency) must deduct Income Tax and NICs before paying you.
- You may receive less take-home pay.
- You won’t receive employee benefits like sick pay or holiday entitlement.
How to Stay Compliant
For Contractors:
- Review contracts: Ensure they reflect a genuine business-to-business relationship.
- Maintain independence: Use your own equipment, have multiple clients, and avoid integration into the client’s organization.
- Document everything: Keep records of contracts, communications, and invoices.
- Seek professional advice: Consult with accountants or legal experts familiar with IR35.
For Clients:
- Assess each engagement: Determine IR35 status for every contractor.
- Provide SDS: Issue a Status Determination Statement for each contractor.
- Handle disputes: Have a process in place to manage disagreements over status determinations.
Tools and Resources
- HMRC’s CEST Tool: Use the Check Employment Status for Tax (CEST) tool to assess IR35 status. Note that while HMRC will stand by the results if accurate information is provided, the tool has faced criticism for reliability.
