- Line 1: Enter the amount of unreported tip income ($10,000)

Tipped Occupation Codes (TTOC) and FICA Tax Credit
The TTOC is a system used by employers to report tips on Form W-2, Box 14b. Employers use the TTOC to report tips for employees in tipped occupations, such as servers and bartenders. The TTOC is used to calculate the employer's tip credit, which can reduce the employer's FICA tax liability (https://www.irs.gov/forms-pubs/about-form-w-2).
The FICA tax credit is a benefit for employers who pay FICA taxes on tips received by employees. The credit is calculated by multiplying the amount of tips reported on Form W-2, Box 14b, by the FICA tax rate (6.2% for Social Security and 1.45% for Medicare).
