SUBJECT: Interest Rates for Calendar Year 2024
Each year, the Indiana Department of Revenue Commissioner is required to establish the applicable interest rates for tax overpayments and underpayments that will take effect for the immediately succeeding calendar year.

Pursuant to
IC 6-8.1-10-1, the rate of interest for an underpayment of tax and an excess tax payment is the percentage rounded to the nearest whole number that equals two percentage points above the average investment yield on state general fund money for the state's fiscal year ending June 30, 2023, excluding pension fund investments, as provided by the State Treasurer's office. The rate of interest for an underpayment of tax and an excess tax payment for calendar year 2024 will be 4%.
A historical list of the above-calculated percentages is attached to this document. If you have any questions concerning this notice, please contact the Tax Policy Division at taxpolicy@dor.in.gov.
