What Are TTOC Codes? A Complete Guide for Employers

If you employ tipped workers — servers, bartenders, valets, hair stylists, or anyone who regularly receives tips — you need to understand TTOC codes. This guide explains everything employers need to know.

What Does TTOC Stand For?

TTOC stands for Treasury Tipped Occupation Code. These are standardized codes assigned by the U.S. Treasury Department to classify tipped employees by their occupation type. Each code is a unique identifier that tells the IRS exactly what kind of tipped work an employee performs.

Why Do TTOC Codes Matter?

The IRS uses TTOC codes for several critical purposes:

W-2 Reporting: Employers must include the correct TTOC code on each tipped employee's W-2 form
Form 8027 Compliance: Large food and beverage establishments must file Form 8027 annually, which requires TTOC codes
Tip Income Tracking: The IRS uses these codes to verify that reported tip income aligns with industry norms
Audit Targeting: Incorrect or missing TTOC codes can trigger IRS scrutiny

How Are TTOC Codes Structured?

TTOC codes follow a simple numeric structure. They are typically 3-digit numbers organized by industry category:

| Code Range | Industry | |-----------|----------| | 101–105 | Food & Beverage (Bartenders, Servers) | | 201–207 | Food & Beverage (Hosts, Bussers) | | 501–511 | Personal Services (Hair Stylists, Barbers) | | 601–611 | Transportation & Hospitality (Valets, Bellhops) | | 801+ | Gaming & Casino |

Each code within a range identifies a specific occupation. For example, Code 101 is specifically for Bartenders, while Code 601 covers Valets.

Pro Tip: If an employee performs multiple tipped roles (e.g., serves and bartends), use the code for their primary tipped occupation — the one where they earn the most tips.

Common Mistakes Employers Make

Avoid these frequent TTOC code errors:

Using the wrong code: A server (Code 207) is different from a bartender (Code 101). Using the wrong code can trigger IRS notices.
Missing codes entirely: Every W-2 for a tipped employee should include the TTOC code. Omitting it raises red flags.
Not updating codes: If an employee changes roles (e.g., from busser to server), update their TTOC code accordingly.
Confusing TTOC with SOC codes: TTOC codes are not the same as SOC codes — they serve different purposes.

What Happens If You Use the Wrong Code?

Using an incorrect TTOC code can lead to:

IRS information requests or notices
Penalties for incorrect W-2 filing
Increased audit risk for your establishment
Employee disputes over tip income reporting
