Business License Fees: On page 4 of the business license application (PDF) is the license tax fee guide to determine the cost of your business license. Example: If your field of business is professional services and you forecast you will make $50,000 the first year, your license tax fee is $114 per schedule + $25 first-time application fee + $4 CASP Fee. Therefore, the total amount of your business license will be $143.
