Understanding IRS Interest Rates for 2020: A Comprehensive Guide

Navigating the complexities of tax payments and refunds can be a daunting task, especially when it comes to understanding interest rates. The Internal Revenue Service (IRS) sets interest rates quarterly, and these rates play a crucial role in determining the amount of interest you may owe on unpaid taxes or the amount of interest you may earn on overpayments. In this comprehensive guide, we will delve into the IRS interest rates for 2020, providing clear explanations, examples, and insights to help you stay informed and make informed decisions regarding your tax obligations.

IRS Interest Rates for 2020: An Overview

For the calendar year 2020, the IRS established the following interest rates:


  • 5% for non-corporate overpayments (4% for corporations)
  • 2.5% for the portion of a corporate overpayment exceeding $10,000


  • 5% for both corporate and non-corporate underpayments
  • 7% for large corporate underpayments (underpayments exceeding $100,000 by C-corporations)

These interest rates are compounded daily, meaning that interest is calculated on the previous day’s balance plus any accrued interest. It’s important to note that these rates are subject to change each quarter, and taxpayers are advised to stay updated on the latest rates published by the IRS.

Understanding the Different Interest Rate Categories

The IRS applies different interest rates based on the type of taxpayer and the nature of the payment or refund. Here’s a breakdown of the categories:

Non-Corporate Overpayments: This category applies to overpayments made by individuals and non-corporate entities. The interest rate for non-corporate overpayments is 5%, compounded daily.

Corporate Overpayments: Overpayments made by corporations are subject to a slightly lower interest rate of 4%, compounded daily. However, if the corporate overpayment exceeds $10,000, the portion of the overpayment above $10,000 earns interest at a rate of 2.5%, compounded daily.

Underpayments: Both corporate and non-corporate underpayments are subject to the same interest rate of 5%, compounded daily. This means that if you fail to pay your taxes on time, you will be charged interest on the unpaid amount at a rate of 5% per year.

Large Corporate Underpayments: C-corporations that underpay their taxes by more than $100,000 are subject to a higher interest rate of 7%, compounded daily. This penalty rate is intended to discourage large corporations from intentionally underpaying their taxes.

How Interest Rates Affect You

Understanding IRS interest rates is crucial for both individuals and businesses. Here’s how these rates can impact you:

Overpayments: If you overpay your taxes, you will earn interest on the overpayment at the applicable rate. This interest is compounded daily, which means it grows over time. While earning interest on overpayments may seem beneficial, it’s generally advisable to avoid overpaying your taxes as it reduces the amount of money you have available for other financial needs.

Underpayments: If you underpay your taxes, you will be charged interest on the unpaid amount at the applicable rate. This interest will continue to accrue until the underpayment is fully paid. It’s important to make timely tax payments to avoid penalties and interest charges.

Staying Informed and Making Informed Decisions

The IRS publishes quarterly interest rates on its website. Taxpayers are encouraged to stay informed about the latest rates to ensure they are aware of the potential impact on their tax obligations. By understanding IRS interest rates, you can make informed decisions about your tax payments and refunds, potentially saving money and avoiding unnecessary penalties.

IRS interest rates play a significant role in determining the amount of interest you may owe on unpaid taxes or earn on overpayments. By understanding the different interest rate categories and how they apply to your situation, you can stay informed and make informed decisions regarding your tax obligations. Remember to refer to the IRS website for the most up-to-date interest rates and consult with a tax professional if you have any specific questions or concerns.
