(a) As soon as practicable after a return is filed, the department may examine it and determine the correct amount of the tax. If an error is disclosed by the examination, the department shall so notify the taxpayer by first-class mail. The taxpayer may petition for redetermination of deficiency as provided in Alaska Stat. § 43.05.240.(b) The same period of limitation upon the assessment and collection of taxes imposed under this chapter and the same exceptions to it shall apply as provided in 26 U.S.C. § 6501 – 6503 (Internal Revenue Code). In the case of additional tax due by reason of a modification, recomputation, or determination of deficiency in a taxpayer’s federal income tax return, the period of limitation on assessment commences from the date that the notice required in Alaska Stat. § 43.20.030(d) is filed, and if no notice is filed the tax may be assessed at any time.
