## Facts

### What Is Form W-4?

Form W-4 is a PDF tax form that informs the employer of the correct amount to withhold from the employee’s paycheck for federal income tax. It contains details on the number of jobs the employee holds, dependents, additional income, and deductions.

### Who Is Required to Fill Out Form W-4?

All new employees are required to fill out Form W-4, as well as anyone whose financial or personal situation changes in a way that affects their income tax. Otherwise, existing employees don’t need to submit a new form each year, as the employer can simply use the information on the previous one.

### When Is Form W-4 Due for Submission?

There is no official due date for Form W-4, but it should be submitted to the employer as part of the onboarding process or within the first month of employment, at the latest. However, employees claiming exemption from withholding taxes must file a new form by February 15th each year.

### What Are the Penalties for Not Submitting the Form?

There are no specific penalties for not submitting Form W-4, but the employer would then withhold taxes as if the employer who failed to file the form were single with no other entries. If this results in less tax being withheld than required, the employee faces a penalty of $500.

### Where Do I File the W-4 Form?

You file the W-4 Form with your employer, not the IRS. You can do so electronically or submit the signed form in person.
