The department of taxation shall cause to be prepared suitable blanks for carrying out the purposes of the laws which it is required to administer, and, on application, shall furnish such blanks to each company, firm, corporation, person, association, partnership, or public utility subject to such laws.
The tax commissioner, when he deems it advisable, may extend to any company, firm, corporation, person, association, partnership, or public utility a further specified time, not to exceed forty-five days, within which to file any report required by law to be filed with the commissioner, in which event the attaching of any penalty for failure to file such report or pay any tax or fee shall be extended accordingly.
