Real property taxes are levied as of the beginning of every real property tax year. A payment of a tax year's real property tax made anytime during that tax year constitutes payment to be applied against such tax levy for the entire tax year, provided that any prior tax year's liability is first satisfied. Consequently, a payment applied to the current tax year or an earlier open period is not refundable, except to the extent that such payment exceeds all of the real property's outstanding tax liabilities, including its liability for the entire, current tax year's real property tax.
Notwithstanding Subsection 1 of this section, a payment of real property tax may, at the discretion of the DCFO, be refunded if the payment thereof is a result of a substantial error that would cause an injustice to the property owner; provided, that no refund shall be allowed to the extent that such refund shall create a delinquency for any half tax year or full tax year.
The tax bill shall include the following:
If mailed, payment for real property taxes, business improvement district taxes and vault rents must be received at the address stated on the bill by the due date and in accordance with the payment instructions stated on the tax bill.
Payments of taxes or other charges levied or imposed under Chapters 8 or 10 of Title 47 (including possessory interest taxes), Business Improvement District (BID) taxes, or vault rents where the property or taxpayer is delinquent as to such tax, rent or charge, shall be applied to such delinquencies based on the date that each arose, beginning with the oldest such delinquency and ending with the current liability, until the payment is exhausted. The payment shall be applied to each such delinquency or liability in the following order: costs, penalties, interest, and the original amount of the tax, rent, or other charge.
