NAICS Code for Consulting

Updated: 2026
Page Type: NAICS Reference (Consulting)

There is no single NAICS code for “consulting.” The correct NAICS code depends on the primary consulting service provided (management, HR, marketing, environmental, engineering, IT/technology, financial, education, etc.). Many consulting firms fall in NAICS 5416 (Management, Scientific, and Technical Consulting Services), especially 541611, 541612, 541613, 541614, 541618, and 541690.

Use the “closest match” approach: pick the code whose description best matches the consulting service that represents the largest share of revenue/work.

No single “consulting” code Most common = 5416 Management = 541611/541618 HR = 541612 Marketing = 541613 Tech/IT often = 541512/541690/541519

How to choose the correct NAICS code for a consulting business

Decision rule: choose the NAICS code that best describes the consulting firm’s primary service.

  • Step 1: Write a one-line description of what you deliver (e.g., “HR policy and benefits consulting”).
  • Step 2: Identify the dominant service line (largest share of revenue; if unknown, use hours/headcount as a proxy).
  • Step 3: Select the most specific NAICS code that matches that service line.
  • Step 4: If you provide multiple types, document the “why” for the chosen primary code.

Most common NAICS codes for consulting companies

Management / business consulting (NAICS 54161)

If none of the specialized 54161 categories fit, many firms default to 541618.

Scientific, technical, and environmental consulting

Advisory services on technical topics, engineering, environmental compliance, and specialized expertise.

The correct code depends on what the firm primarily delivers:
