(1) It is the legislative intent to provide a method for voluntary payment of ad valorem taxes when the tax roll cannot be certified for collection of taxes in time to allow payment prior to January 1 of the current tax year. It is the legislative intent that all taxpayers shall be afforded the opportunity to pay estimated taxes pursuant to this section.
(2) When it appears that it will be impossible for the property appraiser to certify the tax roll for collection in time sufficient to allow payment of current taxes prior to January 1, the property appraiser shall certify such circumstances in writing to the tax collector on or before December 1 and shall provide to the collector a true copy of the preceding year’s tax roll as certified for collection and a statement of current year’s millages from taxing authorities which have so certified. The property appraiser’s certification shall constitute authority for the collector to receive payments of estimated taxes.
(3) Immediately upon receipt of the property appraiser’s certification, the tax collector shall cause to be published in a newspaper of general circulation in the county and shall prominently post at the courthouse door a notice that the tax roll will not be certified for collection prior to January 1 and that payments of estimated taxes will be allowed by those taxpayers who tender payment to the collector on or before December 31.
(4) The tax collector shall accept payment of estimated current taxes based upon an amount equal to the taxes levied against the parcel in the previous year or an amount the tax collector deems to be a more accurate representation of the taxpayer’s current tax liability.
(5) When estimated taxes are paid, the collector shall issue a validated temporary tax notice-receipt. Estimated taxes collected pursuant to this section shall be accounted for, deposited, and distributed as provided generally for ad valorem taxes. However, no distribution shall be made of estimated taxes collected until receipt of a tax roll properly certified for collection, except upon request for an emergency distribution made by the governing body of a taxing authority, certifying a lack of funds for current operations.
(6) Discounts shall not be allowed on payments of estimated taxes, but shall be allowed on the amount of total taxes levied, determined at the time the tax roll has been certified for collection and final tax notice-receipts are issued.
(7) Interest earned on payments of estimated taxes prior to certification of the tax roll for collection shall be retained by the tax collector’s office and disbursed as follows:
(a) First, to pay the expenses of the tax collector’s office in administering and accounting for payments of estimated taxes;
(b) Second, any excess remaining shall be distributed pro rata to the taxing authorities in the proportion that each authority’s tax levy for the prior tax year bears to the total ad valorem tax levy for the prior tax year; however, a taxing authority which has requested and received an emergency distribution of estimated taxes shall not receive this distribution.
(8) Upon receipt of the tax roll certified for collection, the tax collector shall prepare a tax notice-receipt for each taxpayer who has made payment of estimated taxes, showing the amount of estimated taxes paid and the taxes remaining unpaid or any overpayment. Each such tax notice-receipt shall show the periods in which discounts are authorized, the amount of discount, and the discount applied to the estimated taxes with the appropriate remainder due.
(9) After the discount has been applied to the estimated taxes paid and it is determined that an underpayment or overpayment has occurred, the following shall apply:
(a) If the amount of underpayment or overpayment is $5 or less, then no additional billing or refund is required.
(b) If the amount of overpayment is more than $5, the tax collector shall immediately refund to the person who paid the estimated tax the amount of overpayment. Department of Revenue approval shall not be required for the refund of overpayment made pursuant to this subsection.
(10) Any remaining unpaid taxes which become delinquent after notice by the tax collector shall be collected as are other delinquent taxes pursuant to this chapter.
(11) Payment of estimated taxes shall not preclude the right of the taxpayer to challenge his or her assessment as provided in chapter 194.
