Indiana Independent Contractor Misclassification: How the ABC Test Works and What It Costs

Why Indiana's classification standard is stricter than the IRS test

The IRS Common Law Test uses a 20-factor behavioral and financial control analysis. Indiana's Department of Workforce Development uses the ABC test — and the burden of proof is reversed. Under the ABC test, a worker is presumed to be an employee for unemployment insurance (UI) purposes unless the employer can affirmatively prove each of three conditions.

This matters because a worker can pass the federal IRS test — meaning the IRS would classify them as a contractor — while still failing the Indiana ABC test and being reclassified as an employee for UI purposes. An employer can face state UI tax liability even if their federal 1099 treatment is correct.

Indiana's ABC test: what each part requires

To properly classify a worker as an independent contractor for Indiana UI purposes, you must satisfy all three parts:

• Part A — Free from direction and control. The worker must be free from direction and control in the performance of their work — both under the contract terms and in actual practice. It is not enough for a contract to say the worker is independent if you are directing when, where, and how the work is done in practice. Courts and auditors look at behavioral evidence: Do you set their hours? Do you supervise their methods? Do you require them to work at your location?
• Part B — Outside the usual course of business. The worker must perform services either outside the usual course of your business, or outside all places where your business is conducted. This is often the most difficult part to satisfy. A construction company paying a subcontractor to frame walls — the same work the company's direct employees perform — will struggle with Part B. A construction company paying a bookkeeper who works remotely satisfies Part B more easily because bookkeeping is outside the company's usual course of business.
• Part C — Independently established business. The worker must be customarily engaged in an independently established trade, occupation, profession, or business of the same nature as the services they provide. Evidence of this includes: a business entity (LLC, sole proprietorship), a business license, an EIN, a Certificate of Insurance, a website, and evidence of working for other clients. A worker who works exclusively for you with no independent business identity will fail Part C regardless of their contract language.

All three parts must be satisfied simultaneously. Failing any one part is sufficient for the DWD to find the relationship an employment relationship for UI purposes.

What a misclassification finding costs

When the Indiana DWD finds that a worker was misclassified, the consequences are calculated based on the wages paid during the audit period — typically two to three years. The employer owes:

• Back UI taxes on the reclassified wages (state unemployment insurance contributions)
• Interest on unpaid contributions from the date they were due
• Penalties, which can be significant for repeated or willful misclassification

The dollar exposure depends on the number of workers reclassified, the wages paid, the employer's UI tax rate, and the length of the audit period. For employers with multiple contractors performing core business functions — construction crews, staffing agencies, logistics operations — the assessment can be substantial.

Beyond the financial penalty, a misclassification finding creates an administrative record. Subsequent audits will look at whether corrections were made. Willful misclassification — where the employer was previously notified and continued the practice — carries higher penalties.

Industries with the highest Indiana misclassification audit rates

Indiana DWD audit activity is not distributed evenly. Industries with historically high contractor density — where the ABC test is most frequently applied — include:

• Construction and trades: Subcontractor relationships are the most common source of misclassification findings in Indiana. General contractors paying subs who perform the same work as direct employees face significant Part B risk.
• Staffing and temporary labor: Arrangements that look like employee leasing rather than independent business engagements.
• Transportation and logistics: Owner-operator and delivery driver arrangements, particularly where the employer controls routes, hours, and methods.
• Healthcare support: Personal care aides, home health workers, and support staff often fail the independence test when supervision is close.
• Creative and marketing services: Agencies that rely heavily on long-term contractor relationships where the contractor works exclusively for one client.

How to document contractor relationships to satisfy the ABC test

Documentation doesn't change the underlying relationship — but it does preserve your ability to demonstrate the relationship's true character. For each contractor, you should have evidence that addresses all three parts of the test:

• For Part A: A written contract that specifies deliverables, not hours or methods. No supervisor relationship. Evidence that the contractor controls their own work process.
• For Part B: Clear description of why the services are outside your usual course of business — or confirmation that the work is performed away from your places of business with the contractor's own tools and equipment.
• For Part C: Evidence of the contractor's independent business status — business license, EIN, Certificate of Insurance, website, invoices showing they work for multiple clients, Secretary of State registration.

This documentation should be collected before the engagement begins — not after an audit notice. Documentation collected in response to an inquiry is treated with less credibility than documentation that predates the engagement.

Proactive compliance reduces audit exposure

Indiana employers can reduce their exposure to misclassification findings by treating the ABC test as a standard part of contractor onboarding — not a response to a notice. That means evaluating each new relationship against all three parts before work begins, collecting independence documentation as a condition of engagement, and keeping records organized so that any DWD request can be answered promptly.
