Wisconsin businesses must update NAICS codes

May 30, 2018

Businesses that use the Wisconsin Department of Revenue’s "My Tax Account" feature will need to take action soon.

As of June 1, Wisconsin businesses are required to update their NAICS codes before they access their accounts. This will enable the DOR to communicate directly with business sectors on tax law or filing changes and correctly estimate the fiscal impact of tax law changes.

Review the DOR’s new requirement.
