For tax years beginning on or after January 1, 1987, the minimum tax is imposed only to the extent that it exceeds the taxpayer's regular tax liability computed under Iowa Code subsection 42233(1).. The minimum tax rate is 60 percent of the maximum corporate tax rate rounded to the nearest one-tenth of 1 percent or 7.2 percent. Minimum taxable income is computed as follows:
State taxable income as adjusted by Iowa Code section 422.35
Plus: Tax preference items, adjustments and losses added back
Less: Allocable income including allocable preference items and adjustments under Section 56 of the Internal Revenue Code including adjusted current earnings related to allocable income including the allocable preference items Subtotal
Times: Apportionment percentage Result
Plus: Income allocable to Iowa including allocable preference items and adjustments under Section 56 of the Internal Revenue Code including adjusted current earnings related to allocable income including the allocable preference items
Less: Iowa alternative tax net operating less deduction $40,000 exemption amount
Equals: Iowa alternative minimum taxable income
For tax years beginning on or after January 1, 1987, the items of tax preference are the same items of tax preference under Section 57 except for Subsections (a)(1) and (a)(5) of the Internal Revenue Code used to compute federal alternative minimum taxable income. The adjustments to state taxable income are those adjustments required by Section 56 except for Subsections (a)(4) and (d) of the Internal Revenue Code used to compute federal alternative minimum taxable income. In making the adjustment under Section 56(c)(1) of the Internal Revenue Code, interest and dividends from federal securities net of amortization of any discount or premium shall be subtracted. For tax years beginning on or after January 1, 1988, in making the adjustment under Section 56(c)(1) of the Internal Revenue Code, interest and dividends from state and other political subdivisions and from regulated investment companies exempt from federal income tax under the Internal Revenue Code shall be subtracted net of amortization of any discount or premium. In making the adjustment for adjusted current earnings, subtract Foreign Sales Company (FSC) dividend income and Puerto Rican dividend income computed under Internal Revenue Code Section 936 to the extent they are included in the federal computation of adjusted current earnings. Losses to be added are those losses required to be added by Section 58 of the Internal Revenue Code in computing federal alternative minimum taxable income.
Computation of Iowa alternative minimum tax net operating loss deduction.
Net operating losses computed under rule 701-532. (422) carried forward from tax years which begin before January 1, 1987, are deductible without adjustment.
Net operating losses from tax years which begin after December 31, 1986, which are carried back or carried forward to the current tax year shall be reduced by the amount of tax preferences and adjustments taken into account in computing the net operating loss prior to applying rule 701-53.2(422). The deduction for a net operating loss from a tax year beginning after December 31, 1986, which is carried back or carried forward shall not exceed 90 percent of the alternative minimum taxable income computed without regard for the net operating loss deduction.
The exemption amount shall be reduced by 25 percent of the amount that the alternative minimum taxable income computed without regard to the $40,000 exemption exceeds $150,000. The exemption shall not be reduced below zero.
EXAMPLE: The following example shows the computation of the alternative minimum tax when there are net operating loss carryforwards and carrybacks including an alternative minimum tax net operating loss. For tax year 1987, the following information is available:
Federal taxable income before NOL | $182,000 |
Federal NOL carryforward | <97,000> |
Federal income tax | 19,750 |
Tax preferences and adjustments | 48,000 |
Iowa income tax expensed on federal | 2,570 |
Iowa NOL carryforward | 147,000 |
For tax year 1988, the following information is available:
Federal taxable income before NOL | $<154,000> |
Federal income tax refund | 15,460 |
Tax preferences and adjustments | 78,000 |
Iowa income tax refund reported on federal | 2,570 |
The alternative minimum tax for 1987 before the 1988 net operating loss carryback should be computed as follows:
Regular Iowa Tax | |
Federal taxable income | $182,000 |
less 50% federal tax | <9,875> |
add Iowa income tax expensed | 2,570 |
Iowa taxable income before NOL carryforward | $174,695 |
less NOL carryforward | <147,000> |
Iowa taxable income | $ 27,695 |

Alternative Minimum Tax | |
Iowa taxable income before NOL | $174,695 |
add preferences and adjustments | 48,000 |
Total | $222,695 |
less NOL carryforward* | <147,000> |
Iowa alternative taxable income | $ 75,695 |
less exemption amount | <40,000> |
Total | $ 35,695 |
Times 7.2% | 2,570 |
Less regular tax | <1,715> |
Alternative minimum tax | $ 855 |
*Net operating loss carryforwards from tax years beginning before January 1, 1987, are deductible at 100 percent without reduction for items of tax preference or adjustments arising in the tax year.
The alternative minimum taxfor 1987 after the 1988 net operating loss carryback should be computed as follows:
Regular Iowa Tax | |
Federal taxable income | $ 182,000 |
less 50% federal tax | <9,875 > |
add Iowa income tax expensed | 2,570 |
Iowa taxable income before NOL carryforward | $ 174,695 |

*For purposes of the alternative minimum tax, net operating loss carryforward or carryback from tax years beginning after December 31, 1986, must be reduced by items of tax preference and adjustments, and are limited to 90 percent of alternative minimum taxable income before deduction of the post-1986 NOL and the $40,000 exemption amount ($75,695 x 90% = $68,126).
EXAMPLE 1. Taxpayer reported $5,000 of minimum tax for 2007. For 2008, taxpayer reported regular tax of $8,000 and the minimum tax liability is $6,000. The minimum tax credit is $2,000 for 2008 because, although the taxpayer had an $8,000 regular tax liability, the credit is allowed only to the extent that the regular tax exceeds the minimum tax. Since only $2,000 of the carryover credit from 2007 was used, there is a $3,000 minimum tax carryover credit to 2009.
EXAMPLE 2. Taxpayer reported $2,500 of minimum tax for 2007. For 2008, taxpayer reported regular tax of $8,000 and the minimum tax liability is $5,000. The minimum tax credit is $2,500 for 2008 because, although the regular tax exceeded the minimum tax by $3,000, the credit is allowed only to the extent of minimum tax paid for prior tax years. There is no minimum tax carryover credit to 2009.
The separate member's contribution to the amount by which the regular income tax exceeds the tentative minimum tax shall be computed as follows:
[ A/BxC+D ]xF /E = Separate member's contribution to the amount by which regular income tax less credits set forth in section 42233. exceeds the tentative minimum tax.
A = Separate corporation gross sales within Iowa after elimination of all intercompany transactions.
B = Consolidated gross sales within and without Iowa after elimination of all intercompany transactions.
C = Iowa consolidated income subject to apportionment.
D = Separate corporation income allocable to Iowa.
E = Iowa consolidated income subject to tax.
F = The amount by which the regular income tax set forth in Iowa Code section 42233. exceeds the tentative minimum tax.
This rule is intended to implement Iowa Code section 422.33.
