Understanding IR35
Definition
IR35 is a set of tax legislation introduced by the UK government in the Finance Act 2000. This rule is designed to identify individuals who are utilizing intermediaries, such as personal service companies, to provide services to clients that would otherwise be considered employment. Under IR35, these individuals are taxed as employees to ensure appropriate taxation.
Purpose and Impact
IR35 aims to ensure that those working in a manner similar to employees pay broadly the same tax as employees. The legislation affects various areas:
- Pay-As-You-Earn (PAYE) Taxation: Under IR35, earnings must be taxed at source as PAYE income.
- National Insurance Contributions (NICs): Class 1 NICs, typically applicable to employees, are imposed rather than the lower rates applicable to dividend income.
- Expense Deduction Limits: There are stricter rules around what expenses can be deducted when calculating taxable income under IR35, often resulting in less favorable outcomes than if considered self-employed.
Examples
-
IT Contractor Using a Personal Service Company: An IT developer conducts work for a major corporation through their own limited company. Under IR35, if the work arrangement is deemed similar to that of an employee, PAYE rules apply, and they must pay Class 1 NICs.
-
Freelance Graphic Designer: A graphic designer freelances through their service company. If their working conditions are similar to that of a company employee (e.g., set working hours, significant control from the client), IR35 would require them to be taxed as an employee.
Frequently Asked Questions
What Are the Main Criteria for IR35?
The main criteria include the level of control the client has over you, the mutuality of obligation (MOO) to provide and accept work, and whether a substitute could perform the work instead of you.
How Can I Determine If IR35 Applies to Me?
HMRC provides an online tool called the Check Employment Status for Tax (CEST). It helps individuals assess whether their work falls inside or outside IR35.
What Happens If I’m Found Inside IR35?
If inside IR35, you’ll need to calculate and pay PAYE tax and NICs on your payments. This may reduce your take-home pay as compared to treating your compensation as dividends.
Can HMRC Investigate Past Contracts?
Yes, HMRC can investigate past contracts. Typically, they can review records going back up to six years.
Is There Any Legal Recourse for Disputing an IR35 Decision?
Yes, if you disagree with an IR35 determination, you can appeal against the decision through HMRC’s dispute resolution process or eventually through the tax tribunal system.
