(a)   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 taxation or failure to file a return, an additional assessment shall not be made after three years from the time the return was due or filed, whichever is later, provided, however, that 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 of the Federal tax liability shall be one year from the time of the final determination of the Federal tax liability.
   (b)   Taxes erroneously paid shall not be refunded unless a claim for a refund is made within three years from the date of which such payment was made, the return was due, or within three months after final determination of the Federal tax liability, whichever is later. Nonresidents who erroneously paid any municipal income tax shall file an application for a refund within three years of December 31 of the year in which such erroneously payments were made.
