Cash tips received by service employees are federal taxable income and are subject to both federal income tax and FICA taxes for Social Security and Medicare. The Internal Revenue Service U.S. Department of the Treasury requires employees to track and report tip income even when tips are received in cash and not recorded by the employer at the point of sale. Failure to report does not remove the tax obligation; it only shifts compliance and potential penalties to the employee and, in some cases, the employer.
Reporting and withholding
Federal rules require that an employee who receives $20 or more in tips in any one month must report the total to their employer by the 10th day of the following month. The Internal Revenue Service U.S. Department of the Treasury provides Form 4070 Employee’s Report of Tips for this purpose and Publication 15 Employer’s Tax Guide and Form 4137 Social Security and Medicare Tax on Unreported Tip Income to compute tax when tips were not reported to the employer. Employers use reported tip amounts to withhold federal income tax and the employee share of Social Security and Medicare taxes and to record tip income on the employee’s Form W-2. If the employee did not report tips to the employer, the employee must still report them on Form 1040 and may need to use Form 4137 to calculate and pay owed Social Security and Medicare taxes.
Consequences and nuances
When employers operate large food or beverage establishments, they file Form 8027 Employer’s Annual Information Return of Tip Income and Allocated Tips as required by the Internal Revenue Service U.S. Department of the Treasury. If reported tips appear to be below expected levels, the employer may allocate additional tips to employees for reporting on Form W-2; allocated tips are includable in the employee’s taxable income even if the employer did not withhold taxes on them. Culturally and economically, reliance on cash tipping raises enforcement challenges and can disproportionately affect workers in jurisdictions where cash transactions are common or where informal labor is prevalent. Accurate reporting protects employees from unexpected tax bills, ensures proper credit toward Social Security benefits, and reduces employer exposure to withholding liabilities under federal tax rules.
