All taxes imposed by this chapter shall be collectible, together with any interest and penalties thereon, by suit, as other debts of like amount are recoverable. Except in the case of fraud, omission of a substantial portion of income subject to this tax or failure to file a return, an additional assessment shall not be paid after five years from the time of payment of any tax due hereunder. However, in those cases in which the Commissioner of Internal Revenue and the taxpayer have executed a waiver of the Federal statute of limitation, the period within which an additional assessment may be made by the Commissioner of Taxation shall be three years from the time of the final determination of the Federal tax liability. Taxes erroneously paid shall not be refunded unless a claim for refund is made within the time prescribed by Ohio R.C. 718.06.
