Sec. 25.

Application of payments.

Taxpayers have the
right  to  know  how  tax payments and remittances covered by
this Act will be applied to the tax liability owed to  units
of  local  government.    Each  unit of local government must
provide, by ordinance, for the order of  application  of  tax
payments  to  tax  liability, penalty, and interest, provided
that in no case may a payment be  applied  to  penalties  due
before it is applied to tax or interest.  In the event that a
unit  of local government does not provide for application of
payments, any payment or remittance received for a tax period
will be applied first to tax for the period, then to interest
due for the period, and then to penalties due for the period.
