Late summer is when a lot of small businesses add help. School is starting, the fall season is ramping, and bringing someone on as a 1099 contractor feels like the simple option. No payroll setup, no withholding, no unemployment insurance. Just an invoice and a check. That decision is a worker classification decision, and it carries more weight than most owners realize.
The trouble is that worker classification is not a choice you get to make. It is a conclusion that agencies reach by looking at how the relationship actually works, and a signed contract calling someone a contractor carries very little weight if the day to day facts say otherwise. Getting it wrong is one of the more expensive mistakes a small business can make, in part because several different agencies can each reach their own answer.
Three different tests can apply to the same person
This is the part that catches owners off guard. There is no single government definition of a contractor.
The IRS uses a common law test built around three categories. Behavioral control asks who decides how, when, and where the work gets done. Financial control asks who has money at risk, who supplies the tools, and whether the worker can realize a profit or a loss. The relationship category looks at written agreements, benefits, permanence, and whether the work is central to your business.
The Department of Labor governs minimum wage and overtime under the Fair Labor Standards Act, and its standard is in flux. The DOL proposed a new independent contractor rule on February 26, 2026, which would rescind the 2024 framework and return to an economic reality test that gives extra weight to two core factors: control over the work, and the worker’s opportunity for profit or loss based on their own initiative and investment. The comment period closed on April 28, 2026, and the rule was not final as of this writing. Watch for the final version, but do not restructure anything around a proposal.
Your state may be strictest of all. State law usually drives your unemployment insurance and workers compensation exposure, but be aware that a single state often uses different tests for different programs. The unemployment insurance test, the workers compensation test, and the state wage and hour test are not necessarily the same standard, so the right question is always which program you are being measured against.
Colorado and Hawaii do not use the same test
Find your state below, because the two are not interchangeable and a contractor who would pass in one may not pass in the other. Both tests here are the unemployment insurance standards, which are typically the first place a classification problem surfaces.
Colorado applies a modified version of the ABC test, keeping prongs A and C. The worker must be free from your control and direction in performing the work, and must be customarily engaged in an independent trade or business of their own. Colorado does not make you prove the third prong, that the work falls outside your usual course of business, which makes it somewhat more workable than a full ABC state. Colorado also allows a written contract with specific required provisions to create a presumption of independence, but only if the document says the right things and the actual working relationship matches it.
Hawaii applies the full ABC test, including the prong Colorado leaves out. That prong is the hard one, though it is worth reading precisely: the service must be performed either outside your usual course of business or outside all of your places of business. So it is not quite automatic. A landscaping company hiring a landscaper in Hawaii is in a high risk position even if that person has a business license and works for other clients, but the outcome still depends on the specific facts rather than the label on the agreement.
What a misclassification actually costs
The exposure stacks, because each agency assesses its own piece:
- Back federal payroll taxes, both the employer share and the amount you should have withheld, plus penalties and interest
- Back state unemployment insurance contributions and penalties
- Unpaid minimum wage and overtime under the FLSA, plus an equal amount in liquidated damages and the worker’s attorney fees
- Workers compensation exposure, which is the one that can turn a single injury into an uninsured claim
- State level penalties, which in Colorado can escalate for repeat or willful violations
A handful of workers over a few years reaches six figures without much effort. And these cases rarely start with an audit. They usually start with one worker filing for unemployment after the engagement ends, which prompts the state to ask why no contributions were ever made.
A practical way to review your roster
You do not need a legal opinion for every person you pay. You need a consistent process:
- List everyone you paid on a 1099 in the past year and write one sentence describing what they do.
- Flag anyone doing work that is core to what you sell, working only for you, working hours you set, or using your equipment.
- For the ones that pass, confirm the paper trail exists: a signed agreement, their own business license or EIN, their own insurance, and invoices they generated.
- Fix the clear problems going forward rather than hoping no one notices. The cost of converting someone to W-2 now is much smaller than the cost of an assessment later.
If a role is genuinely ambiguous, that is worth a conversation before the next engagement starts, not after it ends.
The bottom line
Worker classification is decided by facts, not labels, and the same person can be judged by three different standards at once. Colorado and Hawaii each apply their own test, and the state test is usually the one that bites first. A short review now, while your fall hiring is still being planned, is far cheaper than sorting it out after a claim.
