2021 Indiana Code|Title 6. Taxation|Article 3. State Income Taxes|Chapter 3. Credits|6-3-3-3. Taxes Paid to Other States; Liability for Income Tax to a Foreign Country

Sec. 3. (a) Whenever a resident person has become liable for tax to another state upon all or any part of the person's income for a taxable year derived from sources without this state and subject to taxation under IC 6-3-2, the amount of tax paid by the person to the other state shall be credited against the amount of the tax payable by the person. Such credit shall be allowed upon the production to the department of satisfactory evidence of the fact of such payment, except that such application for credit shall not operate to reduce the tax payable under IC 6-3-2 to an amount less than would have been payable were the income from the other state ignored. The credit provided for by this subsection shall not be granted to a taxpayer when the laws of the other state, under which the adjusted gross income in question is subject to taxation, provides for a credit to the taxpayer substantially similar to that granted by subsection (b).(b) Whenever a nonresident person has become liable for tax to the state where the person resides upon the person's income for the taxable year derived from sources within this state and subject to taxation under IC 6-3-2, the proportion of tax paid by the person to the state where the person resides that the person's income subject to taxation under IC 6-3-2 bears to the person's income upon which the tax so payable to the other state was imposed shall be credited against the tax payable by the person under IC 6-3-2, but only if the laws of the other state grant a substantially similar credit to residents of this state subject to income tax under the laws of such other state, or impose a tax upon the income of its residents derived from sources in this state and exempt from taxation the income of residents of this state. No credit shall be allowed against the amount of the tax on any adjusted gross income taxable under IC 6-3-2 that is exempt from taxation under the laws of the other state.(c) Notwithstanding subsection (a), if a resident person will be liable for income tax to a foreign country upon the person's income included under the Internal Revenue Code, the income is considered from sources outside the United States under the Internal Revenue Code, and the income is included in the person's Indiana adjusted gross income due solely to an acceleration of the income inclusion for federal income tax purposes, the person may claim the credit allowable under this section by providing evidence to the department of the following:(1) The foreign country in which the income is subject to tax.(2) The amount of income included in Indiana adjusted gross income that is derived from the foreign country.(3) The amount of tax that will be imposed in the foreign country upon the individual's realization of the income under the laws of the foreign country, including any withholding tax or composite tax.(4) Any other information required by the department.The department may impose limitations and conditions on the claim under this subsection, including reporting requirements on the part of the person and extensions of statutes of limitations under IC 6-8.1-5-2.Formerly: Acts 1963(ss), c.32, s.303.
