   29This bill reduces the individual and corporate income tax

   31DIVISION I — FUTURE INDIVIDUAL INCOME TAX RATE CHANGES.
32 The bill reduces the individual income tax rates for the tax
33year beginning January 1, 2025, but before January 1, 2026, as
34follows:
    35Married filing jointly
-7-   1Income over:But not over:Tax rate:
   21) $0$12,0004.00%
   32) $12,0004.40%
    4All other filers other than married filing jointly
   5Income over:But not over:Tax rate:
   61) $0$6,0004.00%
   72) $6,0004.40%
   8The bill further reduces the 3.90 percent individual flat
9income tax rate established for tax years beginning on or after
10January 1, 2026, in 2022 Iowa Acts, chapter 1002, section 20.
11For the tax year beginning on or after January 1, 2026, but
12before January 1, 2027, the bill reduces the individual tax
13rate to 3.55 percent. For the tax year beginning on or after
14January 1, 2027, but before January 1, 2028, the bill reduces
15the individual income tax rate to 2.95 percent. For tax years
16beginning on or after January 1, 2028, the bill reduces the
17individual income tax rate to 2.50 percent.
   18Currently, an alternate income tax calculation exists in
19Code section 422.5. The alternate income tax is an alternate
20method of calculating income tax liability in lieu of the
21regular income tax calculation for taxpayers with income
22slightly above the income tax filing thresholds. The alternate
23method multiplies the taxpayer’s taxable income above the
24income tax filing thresholds in Code section 422.5(2)(b) or
25422.5(3)(b) by the highest existing individual income tax
26rate until the taxpayer’s tax liability is equal to the tax
27liability that would have been calculated under the regular
28income tax calculation method, then after such point the
29regular income tax calculation with the regular income tax
30rates are used. The bill phases in changes to the alternate
31tax rate until the rate is set at 3.00 percent commencing with
32tax years beginning on or after January 1, 2028.
   33After reducing the individual income tax rate to 2.50
34percent, the bill establishes a procedure where the individual
35income tax rate may be adjusted commencing with tax years
-8-1beginning on or after January 1, 2030. The bill specifies
2the individual income tax rate shall be adjusted each tax
3year until the rate is zero, if sufficient funds to make the
4adjustment are available in the taxpayer relief fund.
   5By November 1, 2029, and by November 1 each year thereafter,
6the department of management shall determine the amount of
7moneys available in the taxpayer relief fund, and the net
8individual income tax receipts at the close of the preceding
9fiscal year. The department of revenue shall adjust and apply
10a new individual income tax rate based upon the amount of money
11available in the taxpayer relief fund. The bill specifies the
12department of revenue shall adjust and apply a new individual
13income tax rate in such a way that the rate would have
14generated an amount equal to the net receipts generated from
15the rate in the preceding fiscal year less the amount used in
16the calculation in the taxpayer relief fund.
   17The bill prohibits the rate from being adjusted unless the
18rate is able to be adjusted at least one-tenth of 1 percent.
19The rate, when adjusted, shall be rounded down to the nearest
20one-tenth of 1 percent.
   21The bill requires the moneys in the taxpayer relief fund be
22transferred to the general fund of the state in the fiscal year
23the rate is adjusted.
   24If a tax rate is adjusted, the bill requires the director
25of revenue to cause an advisory notice containing the new
26individual income tax rate to be published in the Iowa
27administrative bulletin and on the internet site of the
28department of revenue. The calculation and publication of the
29adjusted tax rate by the director of revenue is exempt from
30Code chapter 17A, and shall be submitted for publication by the
31first December 31 following the determination date to adjust
32the tax rates.
   33DIVISION II — FUTURE CORPORATE INCOME TAX RATE CHANGES.
34 Under current law, by November 1 of each year, the department
35of management shall determine the net corporate income tax
-9-1receipts for the previous fiscal year, if a determination
2has been made that net corporate income tax receipts for the
3preceding fiscal year exceeded $700 million, the department
4of revenue shall reduce the corporate tax rates and apply the
5adjusted rates for tax years beginning on or after the next
6January 1 following such a determination, but the tax rate
7shall not be adjusted below 5.50 percent. The bill reduces the
8threshold amount for determining if taxes are to be reduced
9from $700 million net corporate income tax receipts to $680
10million net corporate income tax receipts, and reduces the
11lowest possible adjusted corporate tax rate to 4.75 percent.
   12DIVISION III — INSURANCE PREMIUMS TAX. The bill reduces
13the insurance premium tax on the gross amount of premiums
14received by an insurance company from 1 percent to .95 percent
15in calendar year 2025, and from .95 percent to .90 percent for
16the 2026 calendar year and subsequent calendar years.
   17DIVISION IV — SALE OF QUALIFIED STOCK — CAPITAL GAIN
18EXCLUSION. The bill amends Code section 422.7(43), which
19excludes the net capital gain on the sale of certain qualified
20stock and was enacted during the 2022 legislative session.
   21Under the bill, the definition of “employee-owner” is
22modified to include employment at any qualified corporation
23rather than an individual who owns capital stock in a qualified
24corporation for at least 10 years while employed and on account
25of that corporation. The bill modifies the definition of
26“Iowa affiliated group” within the definition of “qualified
27corporation” to include an affiliated group that is eligible to
28make a valid election to file an Iowa consolidated income tax
29return rather than an affiliated group that has made a valid
30election to file an Iowa consolidated income tax return. The
31bill modifies the definition of “member” within the definition
32of “qualified corporation” to include any entity that is
33eligible to be included in a consolidated return rather than
34any entity included in the consolidated return.
   35The division takes effect upon enactment and applies
-10-1retroactively to January 1, 2023, for tax years beginning on
2or after that date.
