How to Report Unreported Tip Income

If you have unreported tip income, you can report it on Form 4137, which is used to report additional tax on tips not previously reported. You'll need to complete Schedule 1 of Form 4137 and attach it to your tax return (https://www.irs.gov/forms-pubs/about-form-4137). You may be able to claim a credit for taxes already paid on the unreported tips.

Here's an example of how to report unreported tip income on Form 4137. Let's say you received $10,000 in cash tips in 2023, but failed to report it to your employer. You'll need to complete Schedule 1 of Form 4137 and report the unreported tip income as follows:

  1. Line 1: Enter the amount of unreported tip income ($10,000)
  2. Line 2: Calculate the additional tax due on the unreported tip income (20% of $10,000 = $2,000)
  3. Line 3: Complete Schedule 1 and attach it to your tax return

Tax Deadlines for Reporting Cash Tips

You must report cash tips to your employer by the 10th day after the end of the month in which you received the tips (https://www.irs.gov/forms-pubs/about-form-w-2). Your employer must report the tips on Form W-2, Box 14b, by January 31 of each year (https://www.irs.gov/forms-pubs/about-form-w-2). You must report unreported tip income on your tax return by the original deadline, typically April 15.

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).
