North American Industry Classification System (NAICS) Codes

Tax Bulletin ST-640 (TB-ST-640)

Printer-Friendly Version (PDF) Issue Date: Updated September 12, 2017

Introduction

If you plan to sell taxable goods or services in New York State, you must register with the Tax Department for sales tax purposes. See Tax Bulletins Do I Need to Register for Sales Tax? (TB-ST-175) and How to Register for New York State Sales Tax (TB‑ST‑360). During the registration process, you will be prompted to select a North American Industry Classification System (NAICS) code to describe your business activity.

What are NAICS codes?

NAICS codes are six-digit codes used to classify businesses according to their economic activity. NAICS is a self-assigned system. You pick the code that best describes your business or organization. More information about NAICS codes is available at the U.S. Census Bureau's website.

What are NAICS codes used for?

The Tax Department uses NAICS codes to improve its communications. For example, if you operate a restaurant and select a corresponding NAICS code, we will not send you information intended for other industries.

The Tax Department also uses NAICS codes to publish aggregated statistical data. We never disclose any taxpayer‑specific data, ensuring that your privacy is protected.

Selecting your NAICS code

The NAICS code you choose should be the one that most closely relates to your principal business activity. Your principal business activity is the one that best describes your line of business. It is usually the activity that generates most of your income.

Please note that your principal business activity might be different from the business activity that requires you to register as a sales tax vendor.

Example: A dentist sells toothbrushes to patients. The dentist registers for sales tax because he sells a taxable personal care product, but he should select a NAICS code based on his principal line of business, his dental practice.

If you have multiple business activities, you can also select a secondary NAICS code.

Example: A hospital registers for sales tax because it charges for parking. The hospital selects a NAICS code based on its principal business activity of being a hospital. The hospital also selects a secondary NAICS code based on its operation of a parking lot.

We have two tools available to help you to determine and select your NAICS code:

Both of these tools are available on our website at www.tax.ny.gov.
