Misclassification cases rarely start with a regulator. They start with a person: a contractor who is let go and files for unemployment, or who asks why they never received leave. The agency then examines the relationship, and the label on the contract is not what it examines.
Here is what actually gets tested, and how to check your own engagements against it.
The contract is not the test
Every major jurisdiction applies a substance-over-form principle. What matters is how the relationship works in practice, not what the paperwork calls it.
This surprises people who have a well-drafted agreement. The agreement matters, but as corroboration. If it says the contractor sets their own hours and the messages show you assigning a 9am start, the messages win.
The three factors that do most of the work
Tests differ by country, but they interrogate the same three things.
Control. Who decides how the work gets done? Not what the outcome is, but the method, the sequence, the hours and the location. A client who specifies a deliverable is buying a service. A client who supervises the process is directing an employee.
Financial risk. Who can lose money? A genuine contractor invests in their own tools, can make a loss on a fixed-price job, and profits from working efficiently. Someone paid a fixed monthly amount, reimbursed for expenses and using your laptop carries no risk at all.
Permanence and exclusivity. Is this an ongoing, open-ended, full-time relationship with one client, or a defined engagement alongside other clients? The more it resembles a job, the more likely it is one.
The US has two different standards
This trips up companies that check one and assume they are covered.
The IRS common-law test looks at behavioural control, financial control and the type of relationship. It is a weighing exercise: no single factor is decisive, and the assessor forms an overall view. See /glossary/irs-20-factor-test and /glossary/common-law-employee.
The ABC test, applied in California and several other states for various purposes, is much harder. The worker is an employee unless you prove all three prongs. Prong B, that the work is outside the usual course of your business, is the one most companies fail: if you are a software company and you hire developers, that work is your usual course of business.
The practical consequence is that the same person can be a legitimate contractor federally and an employee under state law. Check the standard that applies to the specific obligation you are worried about.
There is also a partial shelter in the US: Section 530 safe harbor can protect a business that had a reasonable basis for treating workers as contractors and was consistent about it. It has strict conditions and it is a defence, not a licence.
Elsewhere, briefly
United Kingdom. IR35 asks whether the person would be an employee if you removed the intermediary company. Control, personal service and mutuality of obligation are the core factors, and for medium and large clients the assessment duty sits with the client.
India. No single statutory test. Courts examine control and integration into the organisation. The bigger practical exposure is often statutory: an incorrectly classified worker means unpaid Provident Fund and ESI contributions, with interest and damages. See /glossary/worker-misclassification-india.
Australia. A multi-factor test, with sham contracting provisions that penalise presenting employment as a contracting arrangement.
Germany. Scheinselbstständigkeit, or false self-employment. Working predominantly for one client is a significant indicator, and back social security contributions are the main exposure.
Run the check
The pattern that fails almost everywhere is consistent, and you can screen for it quickly. For each contractor, ask:
- Do you set their working hours?
- Do they use your equipment and internal systems?
- Do they report to a manager in your team structure?
- Have they worked only for you for more than a year?
- Do they do the same work as people you employ?
- Would you have to give notice to end the arrangement?
Several yes answers is not a verdict, but it is the profile assessors look for, and it is worth a proper review rather than a reassurance.
The free misclassification risk check walks through the same factors in a few minutes and gives you a structured result per engagement. It takes no signup.
What to do about a bad result
There are only two honest responses.
Change the facts. Give real autonomy over method and scheduling, stop supplying equipment and internal accounts, define deliverables rather than hours, and allow other clients. This only works if you actually want that relationship. Rewriting the contract while managing the person the same way makes the position worse, because now there is a document contradicted by the evidence.
Convert to employment. If the role is core, full-time and directed, employment is the accurate description. The usual objection is that setting up an entity to employ one person is disproportionate, which is what an Employer of Record solves: the EOR is the legal employer and handles payroll and statutory filings, while you direct the work.
For India, Omnivoo EOR covers all 28 states with Provident Fund, ESI, TDS, Professional Tax and Form 16 handled, from $109 per employee per month at volume, with no entity required and no setup fee.
The bottom line
Misclassification is not a paperwork failure, it is a mismatch between what the paperwork says and what everybody does. Fixing the paperwork alone does not close it.
Run your longest-standing, most full-time contractor through the check first. That is where the exposure concentrates, and it is the engagement most likely to end in the conversation that starts a case.
