What are the 7 core obligations when hiring your first W-2 employee?

EIN (federal), Form I-9 work eligibility verification (federal), Form W-4 tax withholding (federal), new-hire reporting (state), unemployment insurance registration (state), workers' compensation policy (state), and payroll tax withholding and deposits (federal + state).

Which first-hire requirements are federal and uniform everywhere?

EIN, Form I-9, Form W-4, and federal income/FICA withholding. These are identical across all states and governed by the IRS Employer's Tax Guide (Publication 15).

Which requirements vary by state?

New-hire reporting, unemployment insurance registration, and workers' compensation coverage. Requirements and deadlines differ by the state where the employee physically works. Texas is the only state where private employers can legally opt out of workers' comp; all other 49 states mandate coverage from your first employee.

What is the total monthly cost to hire your first employee?

A workable payroll stack runs $40–$80 per month (Gusto payroll) plus a workers' comp policy quoted based on your payroll and class code. Free tools like Erni's Contract Requirement Scanner and Policy Decoder cover paperwork at $0.

What is the deadline for Form I-9 verification?

Within 3 business days of the employee's start date. The completed I-9 must be on file with your business.

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, the tool that satisfies it, and the total monthly cost.

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.
