When you hire your first employee in the US, three things become true within 20 days: you need a federal EIN, you must verify work eligibility with Form I-9, and you owe workers' compensation coverage in almost every state. Workers' comp, unemployment insurance registration, and new-hire reporting are administered by your state, so the exact rules and deadlines vary by where the employee works. This teardown walks one real first hire (a 2-person Austin dev shop hiring employee #3) through every obligation and the tool that satisfies it.
Last updated: August 2026.
TL;DR
- Your first W-2 hire triggers 7 core obligations: EIN, I-9, W-4, new-hire reporting, unemployment tax registration, workers' comp, and payroll tax withholding.
- Federal duties are uniform; workers' comp, unemployment insurance, and new-hire reporting are state-administered and deadlines differ by state.
- Workers' comp is priced by the insurer from your payroll and class code; get a quote from a licensed broker.

Definition box: what "first hire compliance requirements" means
First hire compliance requirements are the legal, tax, HR, and insurance obligations that switch on the moment your business classifies someone as a W-2 employee (not a 1099 contractor). In the US, some are federal and identical everywhere; others are state-administered and vary by the state where the employee physically works. This is information, not legal advice.

What changes legally when you hire your first employee?
The moment you move someone from contractor to employee, you become an employer in the eyes of the IRS and your state labor agency. Here is the concrete workflow, in the order the deadlines actually hit.
