Indiana Code Title 6. Taxation § 6-1.1-9-3

Sec. 3.  (a) If a taxpayer files a personal property return for a particular year, personal property which is omitted from or undervalued on the return may be assessed, or its assessed value may be increased, only if the notice required under section 1 of this chapter is given within three (3) years after the date the return is filed.  However, if the taxpayer's personal property return for a particular year substantially complies with the provisions of this article and the regulations of the department of local government finance, an assessing official or a county property tax assessment board of appeals may change the assessed value claimed by the taxpayer on the return only within the time period prescribed in IC 6-1.1-16-1.

(b) If a taxpayer fails to file a personal property return for a particular year, the taxpayer's personal property may be assessed for that year only if the notice required by section 1 of this chapter is given within ten (10) years after the date on which the return for that year should have been filed.

(c) If a taxpayer files a fraudulent personal property return, or fails to file a return with the intent to evade the payment of property taxes, the assessment limitations prescribed in subsections (a) and (b) do not apply.
