Contractor vs Employee Classification Check
Describe how someone actually works for you, and get a written analysis against the federal tests and your state's rules, plus what to change.
Misclassifying a worker is one of the few mistakes a small organization makes that gets assessed backward across the whole relationship. Unpaid payroll taxes, overtime, benefits, penalties and interest are calculated from the start, not from when someone noticed. It is also easy to do, because most arrangements begin as genuine contract work and drift toward employment over months, without anyone deciding to change anything. A former contractor's claim for unemployment benefits after the work ends is one common way it comes to light.
The label in your agreement does not decide the answer. The tests look at how the relationship works in practice: who controls the work, who carries the financial risk, whether the person runs an independent business, and whether the work is what your organization does every day. Different agencies apply different tests to the same facts, and several states, including California with its ABC test, apply a stricter standard and put the burden on you.
Describe the arrangement in your own words, and attach the agreement or a few invoices if you have them. River writes an analysis of which factors point toward contractor status, which point toward employment, which test is hardest for you to meet, and what would have to change. It is preparation for a conversation with an accountant or employment lawyer, not a determination. To price both routes in dollars, use the contractor vs employee cost comparison. If a key hire belongs on payroll, the employment agreement writer drafts their contract.
Why arrangements drift into employment
Almost nobody sets out to misclassify. The engagement starts as a defined project with a specialist who has other clients. Then it goes well and becomes ongoing. They join the Monday meeting because it is easier than briefing them separately, they get a company email so partners can reach them, and they pick up work outside the original scope. A year and a half later they are a part-time staff member paid on a 1099. Each step was reasonable on its own, which is why nobody noticed the change.
The federal tests weigh many factors together. The IRS groups its evidence into behavioral control, financial control and the type of relationship. The Labor Department asks about economic reality, meaning whether the worker is in business for themselves, and in February 2026 it proposed replacing its 2024 rule on how to apply that test. Because the federal guidance is shifting, the analysis is run against the facts rather than any one checklist.
State law can be stricter. California's ABC test presumes a worker is an employee unless the hiring entity shows all three conditions: freedom from its control, work outside the usual course of its business, and an independently established trade. The middle condition surprises people most. A tutoring nonprofit engaging a tutor has a hard problem even if that tutor sets their own hours, uses their own laptop and has ten other clients.
How it works

Decide what to change
Ask for a contractor agreement that fits, or the questions to bring to your lawyer or accountant.
What you get
- A factor by factor analysis against the IRS and Labor Department tests, quoting your own description
- Your state's test applied, including a stricter standard such as an ABC test where it governs
- A plain risk rating of low, moderate or high, with the specific facts driving it
- The single factor most likely to fail, and what an agency would look at to decide it
- Concrete changes that would support contractor status, or an honest note when none would
- What reclassifying involves, including why past periods need professional advice rather than a quiet fix
Common questions
Is this a legal determination?
No. It is a structured analysis of the factors the tests weigh, applied to what you described. Classification is decided by agencies and courts, and different agencies can reach different answers on the same facts. Treat it as preparation for a conversation with an employment lawyer or accountant, which it should make shorter and cheaper.
Different agencies use different tests. Which one does this use?
The main ones, and it shows where they disagree, because that is the practical problem. A worker can look like a contractor for federal tax purposes and an employee under a state wage or unemployment test. The analysis names the most demanding test that applies to you, since that is the one that sets your real risk.
What if it says the person is probably an employee?
You get the facts driving that result and the realistic paths: restructure the work so it is genuinely independent, bring the person onto payroll, or engage them through an employer of record service. It also explains that exposure for the past does not disappear when you fix the arrangement going forward, which is why the past period belongs with a professional.
Does this apply to nonprofits and volunteers?
Yes. Tax-exempt status does not exempt an organization from classification rules. A volunteer who starts receiving more than nominal pay can become an employee, stipends can be treated as wages, and a grant budget that calls a role contract work does not decide the question. The analysis raises these points when your description suggests them.
Our contractor is in another country. Does this still apply?
US tests generally do not reach a worker hired and working entirely abroad, but the question does not go away. Most countries have their own classification rules, often stricter, and engaging someone abroad can raise tax questions for your organization there. The analysis flags this for local advice instead of applying US factors.
Should I run this before or after signing an agreement?
Before, ideally, because the agreement shapes the facts. A contract that sets hours and supplies your equipment is evidence against contractor status. If someone is already working with you, run it now anyway, since exposure keeps growing for as long as the arrangement continues. When contractor status is workable, River's independent contractor agreement is a good starting point.
