What does a new employee's Form W-4 tell the employer?
How much federal income tax to withhold from their pay.
- Whether the employee may legally work in the US

Why: Form W-4, the Employee's Withholding Certificate, gives filing status, other jobs, credits and deductions. The employer uses it to figure federal income tax withholding from each paycheck.
Huh, didn't know that: The IRS suggests employees fill out a new W-4 each year and whenever their life or finances change.
I'd tell you a joke about withholding, but I'm keeping a little back for later.
