(a) As used in this section:
(1) “Estimated taxes” means the amount that the taxpayer reasonably estimates to be the taxpayer’s tax liability for the City’s income tax for the current taxable year.
(2) “Tax liability” means the total taxes due to the City for the taxable year, after allowing any credit to which the taxpayer is entitled, and after applying any estimated tax payment, withholding payment, or credit from another taxable year.
(b) (1) Every taxpayer shall make a declaration of estimated taxes for the current taxable year, on the form prescribed by the Tax Administrator, if the amount payable as estimated taxes is at least two hundred dollars ($200.00). For the purposes of this section:
A. Taxes withheld for the City from qualifying wages shall be considered as paid to the City in equal amounts on each payment date unless the taxpayer establishes the dates on which all amounts were actually withheld, in which case they shall be considered as paid on the dates on which the amounts were actually withheld.
B. An overpayment of tax applied as a credit to a subsequent taxable year is deemed to be paid on the date of the postmark stamped on the cover in which the payment is mailed or, if the payment is made by electronic funds transfer, the date the payment is submitted. As used in this division, “date of the postmark” means, in the event there is more than one date on the cover, the earliest date imprinted on the cover by the postal service.
(2) Taxpayers filing joint returns shall file joint declarations of estimated taxes. A taxpayer may amend a declaration under rules prescribed by the Tax Administrator. A taxpayer having a taxable year of less than 12 months shall make a declaration under rules prescribed by the Tax Administrator.
(3) The declaration of estimated taxes shall be filed on or before the date prescribed for the filing of municipal income tax returns under Section 192.05(a)(7) or on or before the 15th day of the fourth month after the taxpayer becomes subject to tax for the first time.
(4) Taxpayers reporting on a fiscal year basis shall file a declaration on or before the 15th day of the fourth month after the beginning of each fiscal year or period.
(5) The original declaration or any subsequent amendment may be increased or decreased on or before any subsequent quarterly payment day as provided in this section.
(c) (1) The required portion of the tax liability for the taxable year that shall be paid through estimated taxes made payable to the City including the application of tax refunds to estimated taxes and withholding on or before the applicable payment date, shall be as follows:
A. On or before the 15th day of the fourth month after the beginning of the taxable year, 22.5% of the tax liability for the taxable year;
B. On or before the 15th day of the sixth month after the beginning of the taxable year, 45% of the tax liability for the taxable year;
C. On or before the 15th day of the ninth month after the beginning of the taxable year, 67.5% of the tax liability for the taxable year;
D. For an individual, on or before the fifteenth day of the first month of the following taxable year, 90% of the tax liability for the taxable year. For a person, other than an individual, on or before the fifteenth day of the twelfth month of the taxable year, 90% of the tax liability for the taxable year.
(2) When an amended declaration has been filed, the unpaid balance shown due on the amended declaration shall be paid in equal installments on or before the remaining payment dates.
(3) On or before the 15th day of the fourth month of the year following that for which the declaration or amended declaration was filed, an annual return shall be filed and any balance which may be due shall be paid with the return in accordance with Section 192.05.
(d) (1) In the case of any underpayment of any portion of a tax liability, penalty and interest may be imposed pursuant to Section 192.18 upon the amount of underpayment for the period of underpayment, unless the underpayment is due to reasonable cause as described in Section 192.07(e) of this section. The amount of the underpayment shall be determined as follows:
A. For the first payment of estimated taxes each year, 22.5% of the tax liability, less the amount of taxes paid by the date prescribed for that payment;
B. For the second payment of estimated taxes each year, 45% of the tax liability, less the amount of taxes paid by the date prescribed for that payment;
C. For the third payment of estimated taxes each year, 67.5% of the tax liability, less the amount of taxes paid by the date prescribed for that payment;
D. For the fourth payment of estimated taxes each year, 90% of the tax liability, less the amount of taxes paid by the date prescribed for that payment.
(2) The period of the underpayment shall run from the day the estimated payment was required to be made to the date on which the payment is made. For purposes of this section, a payment of estimated taxes on or before any payment date shall be considered a payment of any previous underpayment only to the extent the payment of estimated taxes exceeds the amount of the payment presently required to be paid to avoid any penalty.
(e) An underpayment of any portion of tax liability determined under Section 192.07(d) shall be due to reasonable cause and the penalty imposed by this section shall not be added to the taxes for the taxable year if any of the following apply:
(1) The amount of estimated taxes that were paid equals at least 90% of the tax liability for the current taxable year, determined by annualizing the income received during the year up to the end of the month immediately preceding the month in which the payment is due.
(2) The amount of estimated taxes that were paid equals at least 100% of the tax liability shown on the return of the taxpayer for the preceding taxable year, provided that the immediately preceding taxable year reflected a period of 12 months and the taxpayer filed a return with the City under Section 192.05 for that year.
(3) The taxpayer is an individual who resides in the City but was not domiciled in the City on the first day of January of the calendar year that includes the first day of the taxable year.
