Tips complicate payroll because they flow through multiple channels and have specific IRS reporting requirements. As an employer, you’re responsible for collecting tip reports from employees, withholding taxes on those reported tips, and keeping records that prove you did everything correctly.

Employees must report their tips to you by the 10th of the following month. This includes cash tips, credit card tips, and any tips received through tip pools. The IRS provides Form 4070 for this purpose, but you can use any system that captures the employee’s name, total tips received, and the reporting period. Most modern POS systems track credit card tips automatically, which simplifies things considerably.

Once you have the reported tips, you withhold federal income tax, Social Security, and Medicare taxes just like you would from regular wages. You also pay the employer portion of FICA taxes on the reported tips. Arizona requires state income tax withholding as well. The tips get added to the employee’s wages on their pay stub even though they’ve already received most of that money directly from customers.

Cash tips are where tracking gets tricky. Credit card tips show up automatically in your POS reports, but cash tips rely on employee honesty. Your job as an employer is to collect the reports and process them correctly. You’re not required to verify the accuracy of what employees report, but you do need a system in place for collecting the reports consistently.

Arizona allows a tip credit, which means you can pay tipped employees below the standard minimum wage as long as their tips bring them above minimum wage. The current Arizona minimum wage is $14.35 per hour with a maximum tip credit of $3 per hour. If tips don’t bring an employee to minimum wage for any pay period, you have to make up the difference.

Large food establishments with more than 10 employees where tipping is customary must file Form 8027 annually with the IRS. This reports total charged tips, total cash sales, and total tip allocation. If your reported tips fall below 8% of gross receipts, you may need to allocate tips to employees for tax purposes.

The easiest setup uses a POS system that tracks tips by employee and exports to your payroll system. Toast, Square, and similar platforms handle credit card tip tracking automatically. Your payroll provider then processes the tips along with regular wages and handles all the withholding calculations.

Common mistakes include forgetting to withhold taxes on cash tips, not collecting monthly tip reports, and miscalculating tip credit. Any of these can result in back taxes, penalties, and interest if the IRS audits you. For restaurants and bars in the Phoenix area, getting payroll configured correctly from the start prevents these problems from compounding over time.
