Tax Tip #160
Interest Paid On A Balance Due
The last tip was about penalties. Now it is time to understand the amount of interest that needs to be paid when there is a balance due after the 4/15 tax deadline on an individual income tax return. For Federal purposes, the interest rate is the current Federal Short-Term Rate (5%) + 3% for a total of 8%. Example: Taxpayer files an extension with the IRS on 4/15/2023 & owes $1K but does not pay the balance due. The tax return is filed on 9/9/2023. The taxpayer owes 1K + a penalty + interest of $28.59 per this online calculator.
