(2) Interest added to tax pursuant to subsection (1) of this section shall be determined in the same manner as interest is determined under section 453A(c) of the Internal Revenue Code except that in determining the interest to be added using section 453A(c) of the Internal Revenue Code:
(a) The interest rate in effect under ORS 305.220 for deficiencies for the month with or within which the taxable year of the taxpayer ends shall be substituted for the underpayment rate referred to in section 453A(c)(2)(B); and
(b) The maximum rate of tax in effect under ORS chapter 316, 317 or 318, whichever is appropriate, shall be substituted for the federal rates of tax referred to in section 453A(c)(3)(B).
(3) The Department of Revenue shall adopt rules consistent with those adopted under section 453A of the Internal Revenue Code and with laws of this state as may be necessary to carry out the provisions of this section, including rules providing for the application of this subsection in the case of contingent payments, short taxable years, pass-through entities and derivation, attribution or apportionment of installment obligations or income from installment obligations.
(4) In the case of a nonresident subject to taxation under ORS chapter 316, in determining whether or not interest is to be added to tax under this section, and the amount of interest to be added, only those installment obligations that arise from dispositions of property in this state shall be taken into consideration.
(5) For purposes of determining interest under ORS 314.395 or penalties under ORS 314.400 or other law, and for purposes of refund, estimated and other prepayments of tax, credits and all other purposes, the interest added under this section shall be considered as any other increase in the tax imposed under ORS chapter 316, 317 or 318, whichever is appropriate.
(6) The interest added to tax imposed under this section shall be assessed and collected under the applicable provisions of this chapter and ORS chapters 305, 316, 317 and 318 and shall be paid over to the State Treasurer and held in the General Fund as miscellaneous receipts available generally to meet any expense or obligation of the State of Oregon lawfully incurred.
