Form 4137

Form 4137 calculates the amount of Medicare and social security taxes owed by an employee on tips. This article will provide you more about the IRS's Form 4137, Social Security, and Medicare Tax on Unreported Tip Income.

Form 4137 is a tax form you must complete along with your federal income tax return. It should be submitted by the due date. The IRS Form 4137 deadline is the same as the federal income tax deadline. If an employee earns over $20 per month in tips, the IRS will require them to report them on Form 4137. If they do not report the tips, the employer will withhold the amount of tax. You should file separate Form 4137s for each spouse.

The amount of tips you earn from your job must be reported to the IRS. To avoid penalties, you must enter your employer and the tips amount in the proper boxes on Form 4137. You must also calculate the Social Security and Medicare taxes on your tips. Here are the line-by-line fillout instructions for Form 4137:
