The question of "how much is IRS interest rate" is a common one, and it's crucial for anyone dealing with the IRS, whether you owe taxes, are expecting a refund, or simply want to understand the system. The IRS interest rates are not static; they change quarterly and are a significant factor in how much you might owe or receive. Let's dive deep into understanding these rates, how they're determined, and what they mean for you.
Are You Curious About IRS Interest Rates? Let's Find Out Together!
Have you ever wondered what happens if you pay your taxes late, or if the IRS takes a long time to send you a refund? Interest is the key word here. The IRS charges interest on underpayments and, in some cases, pays interest on overpayments. Knowing these rates can help you make informed financial decisions and avoid unexpected costs. So, are you ready to unravel the mystery of IRS interest rates? Let's go!

Understanding IRS Interest Rates: A Step-by-Step Guide
Step 1: The Basics of IRS Interest – Why Does it Even Exist?
Before we get into the numbers, it's important to grasp the fundamental reason behind IRS interest rates. The IRS operates on a system of timely payments. When you don't pay your taxes on time, or if you've underpaid throughout the year, the IRS essentially views this as you having used government funds without permission. To compensate for this, they charge interest. Conversely, if the IRS holds onto your overpaid taxes for too long, they may owe you interest. It's a system designed to encourage compliance and fairness.
- Underpayment Interest: This is what the IRS charges you when you don't pay enough tax by the due date. This applies whether you file on time but haven't paid the full amount, or if you've underpaid estimated taxes throughout the year.
- Overpayment Interest (Refund Interest): This is what the IRS might pay you if they take too long to issue your refund after you've overpaid your taxes.
Step 2: How IRS Interest Rates Are Determined – The Federal Short-Term Rate Connection
The IRS doesn't just pull numbers out of a hat. The interest rates are determined quarterly, based on a specific formula tied to economic indicators.
Sub-heading 2.1: The Federal Short-Term Rate
The bedrock of the IRS interest rate calculation is the federal short-term rate (FSTR). This rate is determined by the Secretary of the Treasury for the first month in each calendar quarter. It's then rounded to the nearest full percent (or increased to the next highest full percent if it's a multiple of 1/2 of 1 percent).
Sub-heading 2.2: Adding the Percentage Points
Once the FSTR is established, the IRS adds a specific number of percentage points to it, depending on the type of interest:
QuickTip: Slowing down makes content clearer.
- For Underpayments (Individuals and Corporations): The rate is the federal short-term rate plus 3 percentage points.
- For Overpayments (Individuals and Non-Corporate Entities): The rate is also the federal short-term rate plus 3 percentage points. This means that for individuals, the underpayment and overpayment rates are often the same.
- For Corporate Overpayments (up to $10,000): The rate is the federal short-term rate plus 2 percentage points.
- For the portion of Corporate Overpayments Exceeding $10,000: The rate is the federal short-term rate plus 0.5 (one-half) of a percentage point. This means larger corporate refunds earn less interest.
- For Large Corporate Underpayments (exceeding $100,000): The rate is the federal short-term rate plus 5 percentage points. This is a significantly higher rate to discourage large corporate underpayments.
It's important to remember that interest compounds daily! This means the interest itself starts earning interest, which can significantly increase the total amount owed over time.
Step 3: Current and Recent IRS Interest Rates (as of Q3 2025)
The IRS announces these rates quarterly, so they can fluctuate. Knowing the most recent rates is essential for accurate planning.
For the calendar quarter beginning July 1, 2025, the IRS interest rates are:
- 7% for overpayments (payments made in excess of the amount owed) for individuals.
- 6% for corporate overpayments (up to $10,000).
- 4.5% for the portion of a corporate overpayment exceeding $10,000.
- 7% for underpayments (taxes owed but not fully paid) for individuals.
- 9% for large corporate underpayments (underpayments exceeding $100,000).
Let's look at some recent historical rates to see how they've changed:

As you can see, the rates have been fairly high recently, emphasizing the importance of accurate tax payments.
Reminder: Short breaks can improve focus.
Step 4: When Does IRS Interest Start and Stop?
This is a critical aspect of understanding the true cost or benefit of interest.
Sub-heading 4.1: Interest on Underpayments
- Starts: Generally, interest accrues on any unpaid tax from the original due date of the return (without any extensions) until the date of payment in full.
- Stops: Interest stops accruing on the date the tax liability is paid in full.
Even if you get an extension to file, you still need to pay any tax you owe by the original due date to avoid interest and penalties.

Sub-heading 4.2: Interest on Overpayments (Refunds)
- Starts: The IRS generally has 45 days from the later of the tax return due date or the date the return was actually filed to issue a refund without paying interest. If they don't issue the refund within 45 days, interest generally starts accruing from the tax filing deadline or the date you filed your return, whichever is later.
- Stops: Interest stops on the date the IRS refunds your overpayment (and interest) or offsets it to an outstanding liability.
Step 5: How to Minimize or Avoid IRS Interest Charges
No one wants to pay more to the IRS than necessary. Here's how you can proactively manage your tax payments to minimize or even eliminate interest charges.
Sub-heading 5.1: Pay on Time and Accurately
- File and Pay by the Deadline: This is the most straightforward way to avoid underpayment interest. Even if you can't pay the full amount, filing on time and paying what you can is crucial.
- Adjust Withholding: For employees, review your Form W-4 regularly. If you find yourself owing a lot of tax at the end of the year, adjust your withholding to have more tax taken out of each paycheck.
- Make Estimated Tax Payments: If you're self-employed, have significant investment income, or don't have enough tax withheld from your pay, you're likely required to make estimated tax payments throughout the year (Form 1040-ES). These are typically due quarterly:
- Q1 (Jan 1 to Mar 31): Due April 15
- Q2 (Apr 1 to May 31): Due June 15
- Q3 (June 1 to Aug 31): Due September 15
- Q4 (Sep 1 to Dec 31): Due January 15 of the next year
- The 90% or 100% Rule: To avoid an underpayment penalty (and associated interest), you generally need to pay at least 90% of your current year's tax liability or 100% of your prior year's tax liability (110% if your Adjusted Gross Income in the prior year was over $150,000).
Sub-heading 5.2: What if You Can't Pay?
- File Your Return Anyway: Even if you can't pay, always file your tax return on time. The failure-to-file penalty is much higher than the failure-to-pay penalty.
- Request a Payment Plan: The IRS offers various payment options, such as short-term payment plans (up to 180 days) or installment agreements (monthly payments for up to 72 months). While interest and some penalties still apply, these options can prevent further enforcement actions.
- Offer in Compromise (OIC): If you're in severe financial hardship, you might be able to settle your tax debt for a lower amount through an Offer in Compromise.
Step 6: Penalties vs. Interest – Know the Difference!
It's vital to distinguish between IRS penalties and interest. While both add to your tax bill, they serve different purposes.
- Penalties: These are charges for failing to meet your tax obligations, such as failing to file on time, failing to pay on time, or failing to accurately report income. Penalties can be significant.
- Interest: This is a charge for the use of money. It accrues on unpaid taxes, including unpaid penalties. Unlike penalties, interest generally cannot be waived or reduced, even if you have a good reason for not paying. There are very limited exceptions, such as errors or delays caused solely by the IRS.
