If the amount of tax computed by the county is greater than the amount returned by the business entity, the additional tax shall be assessed and a notice of assessment mailed to the business entity by the county within five years from the date the return was filed, except as otherwise provided in this division (A)(1).
(a) In the case of a failure to file a return or of a fraudulent return, the additional tax may be assessed at any time.
(b) In the case of a return where a business entity understates net profit, or omits an amount properly includable in net profits, or both, which understatement or omission, or both, is in excess of 25% of the amount of net profit stated in the return, the additional tax may be assessed at any time within six years after the return was filed.
(c) In the case of an assessment of additional tax relating directly to adjustments resulting from a final determination of a federal audit, the additional tax may be assessed before the expiration of the times provided in this division (A)(1)(c), or six months from the date the county receives the final determination of the federal audit from the business entity, whichever is later.
