Employment eligibility verification form required for all US hires within 3 days of start.
Form I-9 (Employment Eligibility Verification) must be completed by every employee hired in the United States within 3 business days of their start date. The employee provides identity and work authorization documents (e.g., passport, driver's license + Social Security card), and the employer verifies and records them. I-9s must be retained for 3 years after the hire date or 1 year after termination, whichever is later. E-Verify is the optional electronic system that cross-checks I-9 data with government databases.
On a typical US paystub, form i-9 information appears in one of three sections — the earnings summary, the deductions list, or the year-to-date (YTD) totals — depending on the type of item. Understanding where to find it helps you verify accuracy, catch payroll errors, and prepare for tax season or loan applications.
Whether you receive a digital paystub through your employer's payroll system (such as ADP, Gusto, QuickBooks Payroll, or Paychex) or a traditional paper stub, the information for form i-9 is required by federal labor law to be itemized and accurate. The Fair Labor Standards Act (FLSA) and state-specific wage transparency laws mandate that employees can review and verify each line of their paystub.
Accurate knowledge of form i-9 is essential for several real-world scenarios common to US workers: when applying for an apartment rental (landlords typically require recent paystubs as proof of income), when applying for a car loan or mortgage (lenders verify gross and net pay across multiple paystubs), when filing your annual tax return (IRS Form 1040 reconciles to your year-to-date W-2 or 1099 totals), and when changing jobs (you may need to provide last paystubs to your new employer for benefits eligibility verification).
If you spot an error related to form i-9 on your paystub, US labor law requires your employer to investigate and correct the issue. The American Payroll Association reports that nearly 75% of US workers will experience at least one payroll error during their career, which is why understanding each line item — including form i-9 — is one of the most valuable financial literacy skills you can develop.
