Section 710:50-3-8 - Adjustments by the Internal Revenue Service

(a) If any taxpayer's Federal Income Tax Return is adjusted, an Amended Oklahoma Income Tax Return must be filed within one year. All supporting documentation must be enclosed with an Oklahoma Amended Income Tax Return for the tax year involved. Upon request, the taxpayer must furnish a complete copy of the Federal Income Tax Return, including all schedules, to enable the Tax Commission to determine the correct Oklahoma tax. A recomputation of taxable income under I.R.C. § 1341(a)(5)(B) shall constitute an adjustment to taxable income for the year the income was initially received.

(b) The Commission has two (2) years from the date the return or notice was filed to make an assessment or refund and not thereafter, unless a waiver is agreed to and signed by the Commission and the taxpayer.

(c) In the event of failure by a taxpayer to comply with the requirement set out in (a) of this Section, the statute of limitations is tolled until the Amended Oklahoma Income Tax Return is actually furnished.

(d) When the Internal Revenue Service changes the Federal Income Tax Return by issuing its final determination, the Tax Commission shall have the authority to audit each and every item of income, deduction, credit or any other matter related to the return, where such items or matters relate to allocation or apportionment between the State of Oklahoma and some other state or the federal government, even if such items or matters were not affected by revisions made in such final determination. Where such items or matters do not relate to allocation or apportionment between the State of Oklahoma and some other state or the federal government, the Tax Commission shall be bound by the revisions made in such final determination.
