IRS tightens restaurant tip reporting rules for workers, employers

A dinner rush can end with a pocket full of cash, a card tip left on the receipt, and a split from the tip pool, but the IRS treats all of it as income once it crosses the monthly threshold. Restaurant workers who receive $20 or more in cash tips from one employer in a calendar month must report those tips in writing by the 10th day of the next month.

The agency defines cash tips broadly. That includes direct cash from customers, charged tips paid by credit or debit card and later distributed by the employer, and tips received through tip-sharing arrangements. If tips from one employer stay under $20 in a month, they do not have to be reported and taxes do not have to be withheld on them. Once the total reaches the threshold, the clock starts running.

The written report has to be detailed. It must include the employee’s signature, name, address and Social Security number, along with the employer’s name and address, the month or period covered, and the total tips received. Employers can use their own form or an electronic system as long as it captures the required information. If a worker fails to report tip income to the employer, the IRS says that income may still have to be reported later on Form 4137 with the tax return.

For servers, bartenders and bussers, the stakes go beyond a tax bill. Reported tips feed Social Security and Medicare records, payroll withholding and earnings histories that can matter later for benefits. The Social Security Administration counts tip income in earnings records used to calculate retirement, disability and survivor benefits, and ADP says those reported tips help determine what workers and their families may receive. Sloppy records can leave a worker underreporting income now and shorting future earnings records later.

The rules also matter on the employer side of the pass. Under the Fair Labor Standards Act, a tipped employee is generally someone who customarily and regularly receives more than $30 a month in tips. When an employer uses a tip credit, direct wages plus tips must still reach at least the federal minimum wage and overtime requirements. In large food or beverage establishments, if reported tips fall below 8% of gross receipts, the employer may have to allocate additional tips and report them on Form 8027.

One more distinction catches restaurant workers off guard: service charges added by a club, hotel or restaurant are not tips. The Social Security Administration treats them as wages paid by the employer, not guest gratuities. For workers and managers trying to keep payroll clean, the safest habit is the simplest one: log tips every shift, separate cash from charged tips, and get the monthly report in on time.
