When one or more members withdraw from a partnership or an unincorporated association, the remaining member, or members, may, without incurring additional special (occupational) tax liability, carry on the same business at the same location for the balance of the taxable period for which special (occupational) tax was paid, provided any such change shall be registered in the same manner as required by §479.42. Where new member(s) are taken into a partnership or an unincorporated association, the new firm so constituted may not carry on business under the special tax stamp of the old firm. The new firm must file a return, pay the special (occupational) tax and register in the same manner as a person who first engages in business is required to do under §479.34 even though the name of the new firm may be the same as that of the old. Where the members of a partnership or an unincorporated association, which has paid special (occupational) tax, form a corporation to continue the business, a new special tax stamp must be taken out in the name of the corporation.
