Employees who customarily receive tips are required to report their cash tips to their employers at least monthly, if they receive $20 or more in the month. Cash tips are tips received directly in cash or by check, and charged tips.
If the employee does not report tips to you, it places you at risk of possible assessment of the employer’s share of the Social Security and Medicare taxes on the unreported tips.
If you are a large food or beverage establishment (more than 10 employees on a typical day and food or beverages consumed on the premises), you are required to allocate tips if the total tips reported to you are less than 8% of gross sales. Report the allocated amount on the employee's W-2 at the end of the year.
