What is worker classification?
Definition
Worker classification is the process of determining whether a person performing services should be treated as an employee or an independent contractor. The classification affects taxes, benefits, and compliance with labor laws.
Why worker classification matters
Misclassification can lead to penalties, back taxes, and legal risk. Classifying a worker correctly ensures compliance with employment law, payroll tax obligations, and insurance requirements. It also determines whether a worker is entitled to benefits like paid leave, minimum wage, and protections against unfair dismissal.
How worker classification works
Countries use different tests to determine status, including:
The degree of control over how, when, and where the work is done
Whether the worker provides their own tools and equipment
The level of financial risk and opportunity for profit
Whether the worker can accept multiple clients
In the U.S., the IRS uses a three-part test (behavioral, financial, and relationship control), while the UK uses employment status tests based on contract terms, supervision, and mutuality of obligation.
Example
A company hires a writer who submits weekly articles and invoices monthly. The writer uses their own equipment and chooses topics independently. They are likely a contractor. If instead the company requires them to work specific hours and follow daily instructions, the worker may be misclassified.
