1099 vs W-2 decision tree
Worker classification is the highest-stakes question in workers compensation. Get it wrong and the carrier assesses back-premium, the IRS assesses back-tax, and your state labor agency assesses misclassification penalties. This decision tree applies the federal IRS common-law test by default and switches to California's strict ABC test (AB 5) when the worker's state is CA.

How this tool works
The federal IRS test for worker classification is a totality-of-circumstances common-law test. It groups indicators into three buckets: behavioral control (does the hirer dictate how the work is done), financial control (does the worker have economic independence, multiple clients, ability to profit or loss), and type of relationship (written contract, employee benefits, ongoing engagement). No single answer is dispositive; the auditor or judge weighs the whole pattern.
The seven questions in this tool blend IRS behavioral indicators with the harder ABC-prong-B question, "Is the worker performing tasks that are part of your usual line of business?" Under California's AB 5, prong B is the hardest to satisfy: a software company hiring a contract software developer fails prong B even with full independence on schedule and tools. The tool flags this case explicitly with a "Reclassify to W-2 (high risk)" recommendation.
Each question carries a weight (12-18 points). The tool tallies a percentage employee-leaning score, then maps to a classification: 0-39% = 1099 contractor, 40-64% = Reclassify (mixed signals, audit-vulnerable), 65%+ = W-2 employee. California overrides at the prong-B level: any "yes" to "part of your usual business" triggers Reclassify regardless of the percentage.
The state-specific note shown after the recommendation is pulled from our state-facts dataset, sourced from state labor agency guidance and rating-bureau filings. It captures what the carrier and state will look for at audit. Use the recommendation as decision support, not a legal opinion; for high-stakes engagements consult employment counsel licensed in the worker's state.
Frequently asked questions
What is the difference between the IRS test and the ABC test?
The IRS common-law test weighs three factors (behavioral control, financial control, type of relationship) and looks at the totality of the relationship; no single factor is decisive. California's ABC test is stricter, presuming employee status unless the hirer can prove ALL three prongs: control, performing tasks outside the usual line of business, and engaged in an independently-established business. The tool applies the right test based on the worker's state.
Why does California treat 1099 contractors differently?
Assembly Bill 5 (AB 5), effective 2020, codified the strict ABC test for most worker classifications in California. Misclassification penalties can reach $25,000 per worker per violation, plus the carrier's pass-through workers comp premium reclassification. The tool flags this risk explicitly when the worker's state is CA.
My worker passed the federal test but my state has a different rule?
States can have stricter classification rules than the federal IRS test, but not laxer. The most aggressive state tests are CA (ABC) and MA, NJ, IL (modified ABC variants). The tool applies CA's ABC; for other states it uses IRS common-law. If you operate in MA/NJ/IL, treat the IRS-test recommendation as a floor, not a ceiling, and consult counsel.
What if the worker uses their own tools but I set their hours?
Mixed signals are the hardest case. The IRS treats schedule control (you set hours) as a strong indicator of employment, even if the worker brings their own tools. The tool weights the answers and flags Mediums for "Reclassify to W-2" when the totality leans employee.
How does misclassification affect my workers comp policy?
If your carrier or auditor decides a 1099 should have been a W-2, they will charge premium on the contractor's payments (often at the policy's highest-rated code) and may also assess back-premium for prior years. State labor agencies separately impose misclassification penalties, including criminal charges in CA for wilful violations.
