Frequently Asked Questions

What forms do I need when hiring my first employee?

The essential forms are: Form W-4 (Employee's Withholding Certificate) for federal tax withholding, Form I-9 (Employment Eligibility Verification) to verify work authorization, and your state's W-4 equivalent if required. You'll also need an SS-4 to get your EIN if you don't already have one.

Do I need an EIN to hire an employee?

Yes, you must have an Employer Identification Number (EIN) before hiring employees. You can apply for free on the IRS website or by mailing Form SS-4. Online applications receive their EIN immediately.

When do I need to complete the I-9 form?

The employee must complete Section 1 of Form I-9 on or before their first day of work. You (the employer) must complete Section 2 within 3 business days of the employee's start date. You must physically examine the employee's original identity and work authorization documents.

How do I calculate payroll taxes for my first employee?

For each paycheck, withhold: Federal income tax (based on W-4), Social Security tax (6.2% of gross wages up to $168,600 in 2026), Medicare tax (1.45% of all wages), and state/local taxes if applicable. As the employer, you also pay matching Social Security and Medicare taxes.

Do I have to provide paystubs to employees?

Most states require employers to provide detailed pay stubs showing gross wages, deductions, and net pay. Even in states where it's not required, providing paystubs is a best practice that prevents disputes and helps employees with loans, rentals, and tax filing.

What's the difference between a W-2 employee and a 1099 contractor?

W-2 employees work under your direction, use your equipment, and have taxes withheld. You pay employment taxes for them. 1099 contractors control how they do their work, provide their own tools, and pay their own taxes. Misclassifying employees as contractors can result in significant IRS penalties.

What happens if I don't file the I-9 correctly?

I-9 violations can result in fines from $252 to $2,507 per form for paperwork errors, and $627 to $25,076 per worker for knowingly hiring unauthorized workers. ICE conducts audits, so proper I-9 compliance is essential.
