Except as otherwise provided in this section, the amount of taxes assessable must be assessed within 3-1/2 years after the date the return is filed.
For purposes of this section, a tax return filed before the last day prescribed by law for filing is considered to be filed on the last day.
[Repealed, 2011 c 112 art 2 s 5]
For purposes of computing the limitation under this section, the due date of the property tax refund return as provided for in chapter 290A is the due date for an income tax return covering the year preceding the year in which the property taxes are payable.
Notwithstanding the limitations under subdivision 1, the tax may be assessed at any time if a false or fraudulent return is filed or when a taxpayer fails to file a return.
Additional taxes may be assessed within 6-1/2 years after the due date of the return or the date the return was filed, whichever is later, if:
If a taxpayer fails to make a federal adjustments report as required by subdivision 7 or section 289A.382, the commissioner may recompute the tax, including a refund, based on information available to the commissioner. The tax may be recomputed within six years after the federal adjustments report should have been filed, notwithstanding any period of limitations to the contrary.
If a taxpayer is required to make a federal adjustments report under subdivision 7 or section 289A.382, and does report the change or files a copy of the amended return, the commissioner may recompute and reassess the tax due, including a refund (1) within one year after the federal adjustments report or amended return is filed with the commissioner, notwithstanding any period of limitations to the contrary, or (2) within any other applicable period stated in this section, whichever period is longer. The period provided for the carryback of any amount of loss or credit is also extended as provided in this subdivision, notwithstanding any law to the contrary. If the commissioner has completed a field audit of the taxpayer, and, but for this subdivision, the commissioner's time period to adjust the tax has expired, the additional tax due or refund is limited to only those changes that are required to be made to the return which relate to the changes made on the federal return. This subdivision does not apply to sales and use tax.
For purposes of this subdivision and section 289A.42, subdivision 2, a "field audit" is the physical presence of examiners in the taxpayer's or taxpayer's representative's office conducting an examination of the taxpayer with the intention of issuing an assessment or notice of change in tax or which results in the issuing of an assessment or notice of change in tax. The examination may include inspecting a taxpayer's place of business, tangible personal property, equipment, computer systems and facilities, pertinent books, records, papers, vouchers, computer printouts, accounts, and documents.
A taxpayer may make estimated payments to the commissioner of the tax expected to result from a pending audit by the Internal Revenue Service. The taxpayer may make estimated payments prior to the due date of the federal adjustments report without the taxpayer having to file the report with the commissioner. The commissioner must credit the estimated tax payments against any tax liability of the taxpayer ultimately found to be due to the commissioner. The estimated payments limit the accrual of further statutory interest on that amount. If the estimated tax payments exceed the final tax liability plus statutory interest ultimately determined to be due, the taxpayer is entitled to a refund or credit for the excess, provided the taxpayer files a federal adjustments report, or claim for refund or credit of tax, no later than one year following the final determination date.
Notwithstanding any other provision of this chapter, if a taxpayer whose net income is determined under section 290.01, subdivision 19, omits from income an amount that will under the Internal Revenue Code extend the statute of limitations for the assessment of federal income taxes, or otherwise incorrectly determines the taxpayer's federal adjusted gross income resulting in adjustments by the Internal Revenue Service, then the period of assessment and determination of tax will be that under the Internal Revenue Code. When a change is made to federal income during the extended time provided under this subdivision, the provisions under subdivisions 7 to 9 and section 289A.382 regarding additional extensions apply.
If a deficiency of tax is attributable to a net operating loss carryback that has been disallowed in whole or in part, the deficiency may be assessed at any time that a deficiency for the taxable year of the loss may be assessed.
[Repealed, 2005 c 151 art 1 s 117]
If an employer fails to timely file the reconciliation required by section 289A.09, subdivision 2, paragraph (d), withholding taxes may be assessed within the period prescribed in subdivision 1, or within one year from the date the reconciliation is filed with the commissioner, whichever is later.
If a purchaser refund claim is filed under section 289A.50, subdivision 2a, and the basis for the claim is that the purchaser was improperly charged tax on an improvement to real property or on the purchase of nontaxable services, sales or use tax may be assessed for the cost of materials used to make the real property improvement or to perform the nontaxable service. The assessment may be made against the person making the improvement to real property or the sale of nontaxable services, within the period prescribed in subdivision 1, or within one year after the date of the refund order, whichever is later.
