Learn About IR35 and Umbrella Companies: A Guide for Contractors
Introduction
What is IR35?
IR35, or the off‑payroll working rules, is UK tax legislation designed to distinguish between genuine self‑employment and working like an employee through a limited company. If your contract is “inside IR35,” you’re considered an employee for tax purposes, and your income must be taxed via PAYE. Contracts “outside IR35” allow more flexibility and potential tax efficiencies, but require careful management.
How Umbrella Companies Work
An umbrella company acts as an employer for contractors. When you join one, your pay is processed through PAYE: tax and National Insurance are deducted before you receive your salary. The umbrella company charges a small fee for this service, but in return, it handles all payroll administration, statutory payments, and employment compliance.
Working through an umbrella company simplifies IR35 considerations because you are treated as an employee of the umbrella. This means IR35 does not apply to your pay—you are taxed through PAYE regardless of your contract’s status.
Benefits of Using an Umbrella Company
-
Compliance made simple: PAYE deductions are handled correctly, removing IR35 risk.
-
Employee rights: Contractors receive statutory sick pay, holiday pay, and pension contributions.
-
Flexibility: You can move between contracts without needing to reset a limited company structure.
-
Reduced administration: Payroll, tax submissions, and other paperwork are managed for you.
Things to Be Aware Of
While umbrella companies make contracting easier, there are important considerations:
-
Company transparency: Make sure the umbrella is fully compliant and accredited by recognised bodies like FCSA.
-
Fees and deductions: Understand the umbrella company’s margin and what it covers.
-
Documentation: You should receive a clear employment contract and payslips showing tax deductions.
-
Regulatory changes: From April 2026, legislation may shift some PAYE compliance responsibilities to recruitment agencies or end clients.
Inside vs Outside IR35: Which Route is Right?
-
Inside IR35: Using an umbrella company is often the easiest, fully compliant route. You are treated as an employee for tax purposes, with no additional IR35 risk.
-
Outside IR35: Operating through a limited company can offer tax advantages but comes with additional administrative responsibilities and IR35 assessment risk.
Choosing the Right Umbrella Company
When selecting an umbrella company, look for:
-
Full PAYE compliance and clear tax handling
-
Accreditation from recognised bodies, such as the FCSA
-
Transparent fees and deductions
-
Proper employment documentation and payslips
-
Support for pensions, insurance, and statutory benefits
Summary
IR35 determines your tax status as a contractor. Using an umbrella company allows you to work with peace of mind, knowing your PAYE is correctly applied and IR35 does not affect your pay. While there are costs and considerations, the benefits—compliance, simplicity, and employee rights—make umbrella companies a popular choice for UK contractors.
