If you're an employer dealing with tipped employees, you've likely encountered both TTOC codes and SOC codes. While they both classify occupations, they serve completely different purposes. Mixing them up can cause compliance headaches. Let's clear up the confusion.

Quick Comparison

Feature TTOC Code SOC Code
Full Name Treasury Tipped Occupation Code Standard Occupational Classification
Issued By U.S. Treasury / IRS Bureau of Labor Statistics (BLS)
Purpose Tax reporting for tipped employees Labor market statistics
Used On W-2 forms, Form 8027 BLS surveys, OEWS data
Scope Tipped occupations only (~70 codes) All occupations (~800+ codes)
Format 3-digit numeric (e.g., 101) 6-digit numeric (e.g., 35-3011)

What Are SOC Codes?

SOC (Standard Occupational Classification) codes are maintained by the Bureau of Labor Statistics. They classify every occupation in the U.S. economy — from software engineers to plumbers to CEOs. The SOC system is used for:

  • Labor market research and statistics
  • Salary surveys and compensation benchmarking
  • Immigration applications (H-1B visa labor condition applications)
  • Workforce development programs

For example, the SOC code for "Bartenders" is 35-3011. This code is used for statistical purposes — how many bartenders are employed nationally, what's the average wage, etc.

What Are TTOC Codes?

TTOC (Treasury Tipped Occupation Code) codes are maintained by the U.S. Treasury Department specifically for tax compliance. They only cover tipped occupations and are used on:

  • W-2 forms — to identify what type of tipped work an employee performs
  • Form 8027 — the annual report large food/beverage establishments file with the IRS
  • Tip compliance programs — to track tip income by occupation type

The TTOC code for "Bartenders" is 101 — much simpler than the SOC equivalent.

Why the Confusion?

Employers get confused because:

  1. Both classify the same employees — a bartender has both a SOC code (35-3011) and a TTOC code (101)
  2. Different forms need different codes — BLS surveys want SOC codes; W-2s want TTOC codes
  3. Payroll software doesn't always differentiate — some systems store one but not the other
  4. Neither system references the other — there's no official crosswalk between TTOC and SOC codes

Which One Do You Need?

For tax filing (W-2, Form 8027): Use TTOC codes. Look them up here →

For labor data (BLS surveys, salary research): Use SOC codes. Find them on the BLS website.

For payroll compliance: You likely need both — but the TTOC code is the one that affects your tax filings directly.
