In cities where some special provision is made for demand or collection of taxes, the collector or treasurer shall comply with the special provision, or otherwise be bound by this act.

(2) If demand is sent by mail, the amount of the tax shall be stated along with the place and time where and when the taxes may be paid. The treasurer shall give a receipt for every tax paid, and shall cause to be entered in an indelible manner the fact of payment, and the date of payment upon his or her tax roll.
