Corporate Income Tax
Indiana’s Corporate Adjusted Gross Income Tax is calculated as a flat percentage of the company’s adjusted gross income attributable to the company’s Indiana sales. To determine Indiana’s share of an interstate or international corporation’s taxable income, a company’s adjusted gross income is apportioned based upon a single-sales factor with Indiana’s portion based solely on the portion of the company’s sales in Indiana. Adjusted gross income is a company’s federal adjusted gross income with certain adjustments. This method of determination simplifies tax calculations for corporations and does not apply to S corporations and not-for-profit organizations.
