Can you explain the difference between a W-2 and a W-4 form?

A W-2 form is used by employers to report an employee's annual wages and the amount of taxes withheld from their paycheck. On the other hand, a W-4 form is filled out by employees to inform their employer how much tax to withhold from each paycheck. In summary, a W-2 shows what was earned and withheld, while a W-4 helps determine how much tax is taken out of each paycheck.
