Ohio Rev. Code § 5739.14
If any person liable for the taxes levied by or pursuant to sections 5739.01 to 5739.31, inclusive, of the Revised Code, sells his business or stock of merchandise, or quits his business, the taxes and interest or penalty imposed by or pursuant to such sections on sales made prior to that time shall become due and payable immediately, and such person shall make a final return within fifteen days after the date of selling or quitting business. His successor shall withhold a sufficient amount of the purchase money to cover the amount of such taxes, interest, and penalties due and unpaid until the former owner produces a receipt from the tax commissioner showing that the taxes, interest, and penalties have been paid, or a certificate indicating that no taxes are due. If the purchaser of the business or stock of goods fails to withhold purchase money, he shall be personally liable for the payment of the taxes, interest, and penalties accrued and unpaid during the operation of the business by the former owner.
