Annual Certified Interest Rates

By Oct. 15 of each year, the Ohio Tax Commissioner certifies the interest rates that will apply to overdue taxes during the next calendar year. For most taxes, the interest rate is calculated by adding three percentage points to the federal short-term rate (rounded to the nearest percentage point) that was in effect during July of the current year.

Based on this formula, the Tax Commissioner has certified that the interest rate that will apply to most overdue taxes will be 3 percent. A table of interest rates that apply to previous years may be found below.

Since July 1, 2005, a different rate of interest has applied to overdue estate taxes and tangible personal property taxes. This rate is calculated by simply rounding the federal short term rate to the nearest percentage point. Accordingly, the interest rate on overdue tangible personal property and estate taxes will be 0 percent. See Table 2 for the rate in effect in previous years.

An example of how to calculate interest using these tables is also listed below, as well as copies of recent journal entries certifying these rates.

Interest Rate Formula
Tax due x interest rate x number of days late ÷ number of days in year = Interest
Example: 2011 IT-1040 filed June 21, 2013 with a tax due of $60.00 (return was
due April 17, 2012)
$60.00 x 3% x 258 days ÷ 366 = $1.27
$60.00 x 3% x 172 days ÷ 365= $0.85
Total Interest = $2.12
