Occupational Tax Renewal
Thank you for renewing your Occupational Tax Certificate with the City of Duluth. Please note that the Tax Class number is the number to the right of the decimal point from your NAICS CODE, which is included in the renewal letter. For example, if your NAICS CODE is 44612.2, the Tax Class number is two. The Tax Class Decimal corresponds to the Tax Class number and is located within OPTION A on page two of the renewal packet.
