All taxes imposed by this chapter shall be collectable, together with any interest and penalties there on, by civil action, as other debts of like amount are recoverable. Except in the case of fraud, omission of 25% or more of income subject to this tax or of failure to file a return, an additional assessment shall not be made nor shall a civil action be filed after three years from the time the tax was due or the return was filed, whichever is later, provided, however, in those cases in which a Commissioner of Internal Revenue and the taxpayer have executed a waiver of the Federal statute of limitations, the period within which an additional assessment may be made by the Administrator shall be one year from the time of the final determination of the Federal tax liability.
