(A) As used in this section:

1. (1) "Partial weekly withholding period" means a period during which an employer directly, indirectly, or constructively pays compensation to, or credits compensation to the benefit of, an employee, and that consists of a consecutive Saturday, Sunday, Monday, and Tuesday or a consecutive Wednesday, Thursday, and Friday. There are two partial weekly withholding periods each week, except that a partial weekly withholding period cannot extend from one calendar year into the next calendar year; if the first day of January falls on a day other than Saturday or Wednesday, the partial weekly withholding period ends on the thirty-first day of December and there are three partial weekly withholding periods during that week.
2. (2) "Undeposited taxes" means the taxes an employer is required to deduct and withhold from an employee's compensation pursuant to section 5747.06 of the Revised Code that have not been remitted to the tax commissioner pursuant to this section or to the treasurer of state pursuant to section 5747.072 of the Revised Code.
3. (3) A "week" begins on Saturday and concludes at the end of the following Friday.
4. (4) "Client employer," "professional employer organization," "professional employer organization agreement," and "professional employer organization reporting entity" have the same meanings as in section 4125.01 of the Revised Code.

(B) Except as provided in divisions (C) and (D) of this section and in division (A) of section 5747.072 of the Revised Code, every employer required to deduct and withhold any amount under section 5747.06 of the Revised Code shall file a return and shall pay the amount required by law as follows:

1. (1) An employer who accumulates or is required to accumulate undeposited taxes of one hundred thousand dollars or more during a partial weekly withholding period shall make the payment of the undeposited taxes by the close of the first banking day after the day on which the accumulation reaches one hundred thousand dollars. If required under division (I) of this section, the payment shall be made by electronic funds transfer under section 5747.072 of the Revised Code.
2. (2) Except as required by division (B)(1) of this section, an employer whose actual or required payments under this section were at least eighty-four thousand dollars during the twelve-month period ending on the thirtieth day of June of the preceding calendar year shall make the payment of undeposited taxes within three banking days after the close of a partial weekly withholding period during which the employer was required to deduct and withhold any amount under this chapter. If required under division (I) of this section, the payment shall be made by electronic funds transfer under section 5747.072 of the Revised Code.
3. (3) Except as required by divisions (B)(1) and (2) of this section, if an employer's actual or required payments were more than two thousand dollars during the twelve-month period ending on the thirtieth day of June of the preceding calendar year, the employer shall make the payment of undeposited taxes for each month during which they were required to be withheld no later than fifteen days following the last day of that month. The employer shall file the return prescribed by the tax commissioner with the payment.
4. (4) Except as required by divisions (B)(1), (2), and (3) of this section, an employer shall make the payment of undeposited taxes for each calendar quarter during which they were required to be withheld no later than the last day of the month following the last day of March, June, September, and December each year. The employer shall file the return prescribed by the tax commissioner with the payment.

(D)

1. (1) The requirements of division (B) of this section are met if the amount paid is not less than ninety-five per cent of the actual tax withheld or required to be withheld for the prior quarterly, monthly, or partial weekly withholding period, and the underpayment is not due to willful neglect. Any underpayment of withheld tax shall be paid within thirty days of the date on which the withheld tax was due without regard to division (D)(1) of this section. An employer described in division (B)(1) or (2) of this section shall make the payment by electronic funds transfer under section 5747.072 of the Revised Code.
2. (2) If the tax commissioner believes that quarterly or monthly payments would result in a delay that might jeopardize the remittance of withholding payments, the commissioner may order that the payments be made weekly, or more frequently if necessary, and the payments shall be made no later than three banking days following the close of the period for which the jeopardy order is made. An order requiring weekly or more frequent payments shall be delivered to the employer personally or by certified mail and remains in effect until the commissioner notifies the employer to the contrary.

3. (3) If compelling circumstances exist concerning the remittance of undeposited taxes, the commissioner may order the employer to make payments under any of the payment schedules under division (B) of this section. The order shall be delivered to the employer personally or by certified mail and shall remain in effect until the commissioner notifies the employer to the contrary. For purposes of division (D)(3) of this section, "compelling circumstances" exist if either or both of the following are true:

   1. (a) Based upon annualization of payments made or required to be made during the preceding calendar year and during the current calendar year, the employer would be required for the next calendar year to make payments under division (B)(2) of this section.
   2. (b) Based upon annualization of payments made or required to be made during the current calendar year, the employer would be required for the next calendar year to make payments under division (B)(2) of this section.

(E)

1. (1) An employer described in division (B)(1) or (2) of this section shall file, not later than the last day of the month following the end of each calendar quarter, a return covering, but not limited to, both the actual amount deducted and withheld and the amount required to be deducted and withheld for the tax imposed under section 5747.02 of the Revised Code during each partial weekly withholding period or portion of a partial weekly withholding period during that quarter. The employer shall file the quarterly return even if the aggregate amount required to be deducted and withheld for the quarter is zero dollars. At the time of filing the return, the employer shall pay any amounts of undeposited taxes for the quarter, whether actually deducted and withheld or required to be deducted and withheld, that have not been previously paid. If required under division (I) of this section, the payment shall be made by electronic funds transfer. The tax commissioner shall prescribe the form and other requirements of the quarterly return.
2. (2) In addition to other returns required to be filed and payments required to be made under this section, every employer required to deduct and withhold taxes shall file, not later than the thirty-first day of January of each year, an annual return covering, but not limited to, both the aggregate amount deducted and withheld and the aggregate amount required to be deducted and withheld during the entire preceding year for the tax imposed under section 5747.02 of the Revised Code and for each tax imposed under Chapter 5748. of the Revised Code. At the time of filing that return, the employer shall pay over any amounts of undeposited taxes for the preceding year, whether actually deducted and withheld or required to be deducted and withheld, that have not been previously paid. The employer shall make the annual report, to each employee and to the tax commissioner, of the compensation paid and each tax withheld, as the commissioner by rule may prescribe. Each employer required to deduct and withhold any tax is liable for the payment of that amount required to be deducted and withheld, whether or not the tax has in fact been withheld, unless the failure to withhold was based upon the employer's good faith in reliance upon the statement of the employee as to liability, and the amount shall be deemed to be a special fund in trust for the general revenue fund.

(F) Each employer shall file with the employer's annual return the following items of information on employees for whom withholding is required under section 5747.06 of the Revised Code:

1. (1) The full name of each employee, the employee's address, the employee's school district of residence, and in the case of a nonresident employee, the employee's principal county of employment;
2. (2) The social security number of each employee;
3. (3) The total amount of compensation paid before any deductions to each employee for the period for which the annual return is made;
4. (4) The amount of the tax imposed by section 5747.02 of the Revised Code and the amount of each tax imposed under Chapter 5748. of the Revised Code withheld from the compensation of the employee for the period for which the annual return is made. The commissioner may extend upon good cause the period for filing any notice or return required to be filed under this section and may adopt rules relating to extensions of time. If the extension results in an extension of time for the payment of the amounts withheld with respect to which the return is filed, the employer shall pay, at the time the amount withheld is paid, an amount of interest computed at the rate per annum prescribed by section 5703.47 of the Revised Code on that amount withheld, from the day that amount was originally required to be paid to the day of actual payment or to the day an assessment is issued under section 5747.13 of the Revised Code, whichever occurs first.
5. (5) In addition to all other interest charges and penalties imposed, all amounts of taxes withheld or required to be withheld and remaining unpaid after the day the amounts are required to be paid shall bear interest from the date prescribed for payment at the rate per annum prescribed by section 5703.47 of the Revised Code on the amount unpaid, in addition to the amount withheld, until paid or until the day an assessment is issued under section 5747.13 of the Revised Code, whichever occurs first.
