Note: Refer to s. Tax 2.02 for information concerning reciprocity.
Example: A Wisconsin resident shareholder in a tax-option (S) corporation pays income tax to Iowa on her proportionate share of income from the corporation that is reportable and taxable on both her Wisconsin and Iowa income tax returns for the same taxable year. The tax-option (S) corporation elects to be taxed at the entity level under s. 71.365(4m) (a), Stats., and files and pays Wisconsin franchise tax. The Wisconsin resident shareholder may not claim a credit for net income tax paid to Iowa since the income from the tax-option (S) corporation is not taxable on her Wisconsin income tax return.
Example: A partnership elects to be taxed on income at the entity level under s. 71.21(6) (a), Stats., and pays Wisconsin income tax on income that is also taxable to Iowa for the same taxable year. A Wisconsin resident partner files and pays Iowa income tax on his proportionate share of income from the partnership. The partnership may not claim a credit for tax paid to Iowa since the partnership did not pay the Iowa income tax.
Example: A Wisconsin resident receives income of $4,000 in 2018 from rental property located in Iowa. The person files a 2018 declaration of estimated tax of $200 with Iowa, with $150 of estimated tax payments being made in 2018 and the fourth quarter payment of $50 being made in January 2019. The Iowa income of $4,000 is reported as income on the 2018 Iowa and Wisconsin returns. The 2018 Iowa income tax return shows the following:
2018 Iowa Return
Iowa Rental Income $4,000
Iowa Net Tax $ 185
Estimated Tax Payments 200
Refund $ 15
The taxpayer may claim a credit for net income tax paid to other states of $185 on the 2018 Wisconsin return, even though a part of the tax was paid in 2019.
