Definition of W-2 Tax Form

The W-2 form, officially titled “Wage and Tax Statement,” summarizes an employee’s annual income and the taxes withheld. Employers issue this form in January to both employees and the IRS, ensuring accurate tax compliance and reporting.

Definition of W-4 Tax Form

The W-4 form, named “Employee’s Withholding Certificate,” is submitted by employees to their employers upon starting a job. It specifies the amount of federal income tax to withhold from the employee’s paycheck based on their filing status and allowances.
