Understanding IR35 and Off-Payroll Working for Contractors

The IR35, or off-payroll working rules, were introduced by HMRC to tackle “disguised employment.” These rules apply when contractors work in a way that resembles an employment relationship, even if they’re technically contracted. If a contractor is “inside IR35,” they are taxed similarly to an employee, whereas contractors “outside IR35” retain the self-employed tax treatment. Here, we’ll outline HMRC’s criteria for self-employment, explain “inside” and “outside” IR35, and discuss common scenarios so you can navigate these regulations effectively.

What Defines Self-Employment According to HMRC?

HMRC defines self-employment based on several factors. If “most of the following are true,” HMRC considers a contractor self-employed:

• Bidding and Quoting: They actively put in bids or provide quotes to secure work.
• Autonomy in Work: They perform tasks without direct supervision, demonstrating independence.
• Invoicing: They submit invoices for completed work, unlike employees who receive standard paychecks.
• Tax and NI Responsibilities: Self-employed individuals handle their own National Insurance and tax obligations.
• No Employee Benefits: They do not receive holiday pay, sick pay, or other employee benefits.
• Contractual Terms: Their contract may use terms like “self-employed,” “consultant,” or “independent contractor,” reflecting a non-employee relationship.

Meeting most of these criteria typically classifies a contractor as “outside IR35,” granting them the benefits of self-employed tax treatment.

Inside IR35 vs. Outside IR35: What Do They Mean?

• Inside IR35: When a contractor falls “inside IR35,” they do not meet HMRC’s self-employment criteria and are treated like an employee for tax purposes. This classification means they must pay PAYE income tax and National Insurance Contributions (NICs) similar to an employee. Contractors inside IR35 should be on a payroll, either through the company they contract with or via an umbrella company.
• Outside IR35: If a contractor meets HMRC’s criteria for self-employment, they are considered “outside IR35.” This classification allows them to operate as a sole trader or through their own limited company, benefitting from the tax advantages associated with self-employment. They can receive payments directly through their company, which are treated as business profits and taxed at the corporate rate, often leading to greater tax efficiency.

Common Scenarios and How IR35 Applies

In many cases, the client or employer will clarify if a contract falls inside or outside IR35 when the contract is issued. Here are some common scenarios that illustrate the impact of IR35:

• Client Classification: When an agreement is reached, many employers will disclose the IR35 status. The aim of IR35 is to ensure that tax liabilities are correctly assessed, so the tax difference should not be substantial in most cases. However, “outside IR35” status can be preferable due to tax efficiency.
• Limited Company Payments: For contractors outside IR35, payments are typically made directly to their limited company. This income is treated as company profit, which may offer a favorable tax position compared to inside IR35. Inside IR35 status requires the contractor’s income to go through payroll, meaning it’s subject to higher individual tax rates.
• National Insurance Responsibilities: Contractors inside IR35 must cover both employee and employer National Insurance Contributions, increasing their tax liability compared to those outside IR35, who only need to meet standard self-employed NIC obligations.

Why IR35 Status Matters

IR35 status affects both tax liabilities and the financial structure of payments. Being outside IR35 is often advantageous, as it allows contractors to manage their taxes efficiently, retain control over invoicing and other business aspects, and avoid paying additional NICs that would be required inside IR35. Conversely, contractors inside IR35 are essentially treated as employees for tax purposes, diminishing the flexibility and financial benefits of self-employment.
