This research is verified for the main employer-facing point: a 1099 form does not decide whether someone is an independent contractor. Federal tax, federal wage-and-hour law, state unemployment law, state wage-payment law, and industry-specific rules can apply different tests to the same worker.
The most important correction is still preserved: the broad wage/payment ABC states are California, Massachusetts, and New Jersey. Vermont and Connecticut use ABC in unemployment contexts, but they are not presented as broad general wage/payment ABC states. Illinois is treated as strict for construction and unemployment, not as a single across-the-board wage/payment ABC state.
The federal DOL posture is current as of May 30, 2026. The 2024 independent-contractor final rule remains the published Part 795 regulation unless rescinded, while the Department has announced a 2026 proposed rescission and a different current-enforcement posture. That is a confusing legal posture for employers, and the research explains it without pretending the uncertainty is settled.
For a small business owner, the practical takeaway is accurate: do not rely on the contract label alone. Look at control, economic dependence, whether the work is part of the company's usual business, whether the worker has an independent business, and which state or agency is asking the question.
