(a) Any state agency may establish a requirement, within its area of administrative responsibility, that every person, corporation or partnership, owing, in connection with an individual transaction consisting of any State of Alabama tax return, fee, report or other document, or any other obligation of indebtedness to the state, an amount of money, as specified in subsection (b) shall pay such tax liability, fee, or obligation to the state no later than the date such payment or remittance of funds is required by law, in funds which are immediately available to the state on the first banking day following the due date of payment.

(b) The determination as to which persons, corporations or partnerships shall be subject to the remittance provisions of this article is based on individual payments made during a calendar year, rather than the aggregate of payments made during a calendar year. Persons, corporations, or partnerships making an individual payment at the thresholds indicated below shall comply with this article and subsection (c):

(1) Twenty-five thousand dollars ($25,000) or more for payments made during the calendar year.

(2) On taxes, fees, and other obligations that are collected or administered by the Department of Revenue:

a. Seven hundred fifty dollars ($750) or more for payments by a business entity made after October 1, 2006, and all filing periods thereafter shall be paid electronically.

For purposes of this subdivision, electronically includes payments made over the telephone.

b. All local government business entity taxes and fees collected or administered by the department when the corresponding state tax is subject to paragraph a., shall also be paid electronically.

c. Notwithstanding paragraphs a. and b., the department, by rule, may designate specific revenue sources, fees, or monetary obligations which it may except from paragraphs a. and b.

d. The governing body of any self-administered county or city may elect to require electronic payments under the same provisions of this subdivision applicable to the department.

(c) When the provisions of subsection (a) are established, payment and the reporting of such remittance shall be made in accordance with procedures established by the administering state agency for the indebtedness involved; such procedures shall continue to be the method of reporting and remittance until established otherwise by the administering state agency.

(1) Such procedures shall include the use of the automated clearing house system.

(2) The state administrating agency shall coordinate with the State Treasurer to insure the availability of such funds to the state on the first banking day following the due date of payment.
