(b-1) Notwithstanding the deadline prescribed by Subsection (b) for payment of the first installment, a person to whom this section applies may pay the taxes in four equal installments as provided by Subsection (b) if the first installment is paid and the required notice is provided before the first day of the first month after the delinquency date.
(c) If the person fails to make a payment before the applicable date provided by Subsection (b), the unpaid installment is delinquent and incurs a penalty of six percent and interest as provided by § 33.01(c).
