Indiana Code
Chapter 4. Research Expense Credits
6-3.1-4-2. Amount of Credit; Computation

Sec. 2. (a) A taxpayer who incurs Indiana qualified research expense in a particular taxable year is entitled to a research expense tax credit for the taxable year.
(b) For Indiana qualified research expense incurred before January 1, 2008, the amount of the research expense tax credit is equal to the product of ten percent (10%) multiplied by the remainder of:
(1) the taxpayer's Indiana qualified research expenses for the taxable year; minus
(2) the taxpayer's base amount.
(c) Except as provided in subsection (d), for Indiana qualified research expense incurred after December 31, 2007, the amount of the research expense tax credit is determined under STEP FOUR of the following formula:
STEP ONE: Subtract the taxpayer's base amount from the taxpayer's Indiana qualified research expense for the taxable year.
STEP TWO: Multiply the lesser of:
(A) one million dollars ($1,000,000); or
(B) the STEP ONE remainder;
by fifteen percent (15%).
STEP THREE: If the STEP ONE remainder exceeds one million dollars ($1,000,000), multiply the amount of that excess by ten percent (10%).
STEP FOUR: Add the STEP TWO and STEP THREE products.
(d) For Indiana qualified research expense incurred after December 31, 2009, a taxpayer may choose to have the amount of the research expense tax credit determined under this subsection rather than under subsection (c). At the election of the taxpayer, the amount of the taxpayer's research expense tax credit is equal to ten percent (10%) of the part of the taxpayer's Indiana qualified research expense for the taxable year that exceeds fifty percent (50%) of the taxpayer's average Indiana qualified research expense for the three (3) taxable years preceding the taxable year for which the credit is being determined. However, if the taxpayer did not have Indiana qualified research expense in any one (1) of the three (3) taxable years preceding the taxable year for which the credit is being determined, the amount of the research expense tax credit is equal to five percent (5%) of the taxpayer's Indiana qualified research expense for the taxable year.
