If any vendor fails to collect the tax or any consumer fails to pay the tax imposed by or pursuant to section 5739.02, 5739.021, 5739.023, or 5739.026 of the Revised Code, on any transaction subject to the tax, the vendor or consumer shall be personally liable for the amount of the tax applicable to the transaction. The commissioner may make an assessment against either the vendor or consumer, as the facts may require, based upon any information in the commissioner's possession.
An assessment against a vendor when the tax imposed by or pursuant to section 5739.02, 5739.021, 5739.023, or 5739.026 of the Revised Code has not been collected or paid, shall not discharge the purchaser's or consumer's liability to reimburse the vendor for the tax applicable to such transaction.
An assessment issued against either, pursuant to this section, shall not be considered an election of remedies, nor a bar to an assessment against the other for the tax applicable to the same transaction, provided that no assessment shall be issued against any person for the tax due on a particular transaction if the tax on that transaction actually has been paid by another.
The commissioner may make an assessment against any vendor who fails to file a return or remit the proper amount of tax required by this chapter, or against any consumer who fails to pay the proper amount of tax required by this chapter. When information in the possession of the commissioner indicates that the amount required to be collected or paid under this chapter is greater than the amount remitted by the vendor or paid by the consumer, the commissioner may audit a sample of the vendor's sales or the consumer's purchases for a representative period, to ascertain the per cent of exempt or taxable transactions or the effective tax rate and may issue an assessment based on the audit. The commissioner shall make a good faith effort to reach agreement with the vendor or consumer in selecting a representative sample.
The commissioner may make an assessment, based on any information in the commissioner's possession, against any person who fails to file a return or remit the proper amount of tax required by section 5739.102 of the Revised Code.
The commissioner may issue an assessment on any transaction for which any tax imposed under this chapter or Chapter 5741. of the Revised Code was due and unpaid on the date the vendor or consumer was informed by an agent of the tax commissioner of an investigation or audit. If the vendor or consumer remits any payment of the tax for the period covered by the assessment after the vendor or consumer was informed of the investigation or audit, the payment shall be credited against the amount of the assessment.
The commissioner shall give the party assessed written notice of the assessment in the manner provided in section 5703.37 of the Revised Code. With the notice, the commissioner shall provide instructions on how to petition for reassessment and request a hearing on the petition.
Immediately upon the filing of the entry, the clerk shall enter a judgment for the state against the party assessed in the amount shown on the entry. The judgment may be filed by the clerk in a loose-leaf book entitled "special judgments for state, county, and transit authority retail sales tax" or, if appropriate, "special judgments for resort area excise tax," and shall have the same effect as other judgments. Execution shall issue upon the judgment upon the request of the tax commissioner, and all laws applicable to sales on execution shall apply to sales made under the judgment except as otherwise provided in this chapter.
If the assessment is not paid in its entirety within sixty days after the date the assessment was issued, the portion of the assessment consisting of tax due shall bear interest at the rate per annum prescribed by section 5703.47 of the Revised Code from the day the tax commissioner issues the assessment until the assessment is paid or until it is certified to the attorney general for collection under section 131.02 of the Revised Code, whichever comes first. If the unpaid portion of the assessment is certified to the attorney general for collection, the entire unpaid portion of the assessment shall bear interest at the rate per annum prescribed by section 5703.47 of the Revised Code from the date of certification until the date it is paid in its entirety. Interest shall be paid in the same manner as the tax and may be collected by issuing an assessment under this section.
