Interest Rates and Calculation

Interest is calculated using the number of calendar days from the original due date of the return until the tax is paid. Interest can be calculated using this formula:

(unpaid tax) x (interest rate) x (number of days) ÷ 365 = Amount of Interest Due

Interest Rates

Note: payments are applied first to penalties, secondly to interest and lastly to tax. See Rule R861-1A-18.
