Ever felt that sinking feeling when you realize you might owe the IRS more than you thought, or worse, that you're late on a payment? You're not alone! Many taxpayers find themselves in this predicament, and one of the most pressing questions that arises is: "How much interest does the IRS charge per day?"
It's a crucial question because those daily charges can really add up. Understanding the mechanics of IRS interest, how it's calculated, and what factors influence it is vital for any taxpayer. This comprehensive guide will break down everything you need to know, from the current rates to practical steps you can take.
Step 1: Let's Acknowledge the Elephant in the Room – Unpaid Taxes!
Before we dive into the nitty-gritty of interest calculations, let's address the fundamental issue. If you're reading this, chances are you're concerned about unpaid taxes. Perhaps you underpaid your estimated taxes, missed the filing deadline, or simply couldn't afford your tax bill when it was due. Whatever the reason, ignoring it won't make it disappear. In fact, it will only make the problem grow due to accumulating interest and potential penalties.
- Don't panic! While the IRS can seem intimidating, they also have procedures in place to help taxpayers resolve their liabilities. The key is to act promptly and understand the situation.

Step 2: Understanding the IRS Interest Rate: It's Not Static!
The first thing to grasp is that the IRS interest rate isn't a fixed, unchanging number. It's actually a dynamic rate that the IRS determines and announces on a quarterly basis.
Sub-heading: How the Rate is Determined
The IRS interest rate is tied to the federal short-term rate plus a certain percentage. This federal short-term rate is based on the average market yields of marketable U.S. government obligations with maturities of three years or less.
For most individual taxpayers, the interest rate on underpayments is the federal short-term rate plus three percentage points. For corporations, the rates can vary slightly for overpayments and large underpayments.
Sub-heading: Current and Recent Rates (as of June 2025)
The IRS recently announced that the interest rates will remain the same for the calendar quarter beginning July 1, 2025.
Here are the rates for the second and third quarters of 2025:
Tip: Reading twice doubles clarity.
- For individuals (overpayments and underpayments): 7% per year, compounded daily.
- For corporations (overpayments): 6% per year.
- For the portion of a corporate overpayment exceeding $10,000: 4.5% per year.
- For underpayments (taxes owed but not fully paid): 7% per year for most taxpayers.
- For large corporate underpayments: 9% per year.
Remember: These rates are annual percentages. The crucial part is how they're applied.
Step 3: The Daily Compounding Factor: Where the "Per Day" Comes In
This is where the interest truly starts to add up. The IRS compounds interest daily. What does this mean?
Sub-heading: Simple vs. Compound Interest
- Simple Interest: Interest is calculated only on the original principal amount.
- Compound Interest: Interest is calculated on
the original principal amount and on the accumulated interest from previous periods.
Because the IRS compounds interest daily, each day, the interest you owe is calculated on your original unpaid tax amount plus any interest that has already accrued. This can lead to a significant increase in your total tax liability over time, making it even more urgent to address unpaid balances quickly.
Step 4: Calculating the Daily Interest: A Step-by-Step Approach
While the IRS handles the precise calculations, understanding the general formula can give you a clear picture of what you're facing.
Sub-heading: The Basic Formula
To get a rough idea of the daily interest, you can use this simplified approach:
- Find the Annual Interest Rate: As mentioned, for most individuals, it's currently 7%.
- Convert to a Daily Rate: Divide the annual rate by 365 (or 366 in a leap year).
- Example:
- Multiply by the Unpaid Balance: Take your outstanding tax amount and multiply it by the daily interest rate.
- Example: If you owe , then per day.
Sub-heading: The Compounding Effect in Action
Let's illustrate with an example:
-
Initial Unpaid Tax: $1,000
-
Annual Interest Rate: 7%
-
Daily Interest Rate (approx): 0.00019178
-
Day 1 Interest:
-
New Balance (for Day 2):
-
Day 2 Interest:
-
New Balance (for Day 3):
As you can see, even small daily amounts add up because the base on which the interest is calculated grows each day. This is why delaying payment can be so costly.
Tip: Patience makes reading smoother.

Step 5: When Does Interest Start Accruing?
Interest generally begins to accrue on any unpaid tax from the original due date of the return (without any extensions) until the date the tax is paid in full.
- Even if you file an extension: An extension to file your return does not extend the time to pay your taxes. Interest will still start accruing from the original due date (typically April 15th for individuals).
Step 6: Penalties vs. Interest: Know the Difference
It's important to differentiate between IRS interest and penalties. They are separate charges, though interest can also be charged on penalties.
Sub-heading: Common IRS Penalties
- Failure to File Penalty: This is typically 5% of the unpaid taxes for each month or part of a month your return is late, up to a maximum of 25%.
- Failure to Pay Penalty: This is usually 0.5% of the unpaid taxes for each month or part of a month the tax remains unpaid, up to a maximum of 25%.
- Underpayment of Estimated Tax Penalty: This applies if you didn't pay enough tax throughout the year through withholding or estimated tax payments.
Interest is charged on these penalties as well, starting from the date the penalty is assessed. This is why the total amount owed can sometimes seem surprisingly high.
Step 7: What to Do If You Owe Money to the IRS
Facing a tax bill you can't immediately pay can be daunting, but there are proactive steps you can take to mitigate the impact of interest and penalties.
Sub-heading: Pay as Much as You Can, As Soon As You Can
- Even if you can't pay the full amount, pay what you can. Every dollar paid reduces the principal balance on which interest is calculated, immediately lowering your daily interest charges.
Sub-heading: Explore Payment Options
The IRS offers several options for taxpayers who can't pay their tax bill in full:
- Short-Term Payment Plan: You might be granted up to 180 days to pay your tax liability in full, though interest and penalties will continue to accrue.
- Installment Agreement: This allows you to make monthly payments for up to 72 months. While interest and penalties still apply, the failure-to-pay penalty rate is reduced while an installment agreement is in effect.
- Offer in Compromise (OIC): This allows certain taxpayers to settle their tax liability for a lower amount than what they owe. An OIC is generally considered when taxpayers are experiencing significant financial hardship.
- Delaying Collection (Currently Not Collectible Status): If the IRS determines you're unable to pay your tax liability and meet basic living expenses, they may delay collection until your financial situation improves. However, interest and penalties continue to accrue during this period.
Sub-heading: Seek Professional Help
If your tax situation is complex or you're unsure about the best course of action, consider consulting a tax professional, such as a tax attorney or an enrolled agent. They can help you understand your options, negotiate with the IRS, and ensure you're taking the most advantageous steps.
Step 8: Can IRS Interest Be Reduced or Waived?
Generally, IRS interest cannot be waived or reduced, even if you have a good reason for not paying on time. This is because interest is considered statutory, meaning it's mandated by law.
QuickTip: Reread tricky spots right away.
However, there are very limited exceptions:
- IRS Error or Delay: If the interest is due to an unreasonable error or delay by an IRS officer or employee, you may be able to request an abatement of interest by filing Form 843, Claim for Refund and Request for Abatement.
- Certain Disaster Situations: In some federally declared disaster areas, the IRS may provide relief from penalties and interest for affected taxpayers.
It's crucial to understand that these are exceptions, not the rule. The primary way to reduce IRS interest is to pay your tax liability as quickly as possible.
Frequently Asked Questions (FAQs)
How to calculate IRS interest on a specific amount?
To get a rough daily estimate, divide the annual interest rate (e.g., 7% or 0.07) by 365, then multiply that daily rate by your unpaid tax balance. Keep in mind the IRS compounds interest daily, so the exact calculation is more complex and best left to IRS systems.
How to find the current IRS interest rates?
The IRS announces its quarterly interest rates on its official newsroom website. You can typically find these by searching for "IRS interest rates [current year] quarter" or "IRS newsroom interest rates."
How to stop IRS interest from accruing?
The most direct way to stop interest from accruing is to pay your outstanding tax balance in full. If you cannot pay in full, paying as much as possible will reduce the principal amount on which interest is calculated, thereby reducing the daily interest charge.
How to avoid IRS interest in the future?
To avoid IRS interest, ensure you pay your full tax liability by the original due date of your return. For estimated taxes, make sure your withholdings or quarterly payments cover
QuickTip: Re-reading helps retention.
How to set up an IRS payment plan?
You can apply for an Online Payment Agreement through the IRS website if you owe $50,000 or less in combined tax, penalties, and interest, and have filed all required returns. You can also apply by mail using Form 9465, Installment Agreement Request, or by calling the IRS.
How to determine if I owe IRS penalties in addition to interest?
The IRS will typically send you a notice or bill if you owe penalties. Common penalties include failure to file, failure to pay, and underpayment of estimated tax. Interest accrues on these penalties too.
How to request an abatement of IRS interest?
You can request an abatement of interest by filing Form 843, Claim for Refund and Request for Abatement, if the interest was due to an unreasonable error or delay by an IRS officer or employee. Supporting documentation is crucial for this request.
How to get more information on specific IRS interest calculations?
For detailed information on IRS interest calculations, refer to IRS Publication 505, Tax Withholding and Estimated Tax, or consult the Internal Revenue Manual (IRM) Part 20.2, Interest. For personalized assistance, contact the IRS directly or a tax professional.
How to check my IRS account balance, including interest and penalties?
You can check your IRS account balance, including any interest and penalties, by creating or logging into your IRS online account on the official IRS website. You can also call the IRS directly or request a transcript of your tax account.
How to handle a large corporate underpayment and associated interest?
Large corporate underpayments face higher interest rates (currently 9%). Corporations should aim to pay their full tax liability by the due date. If an underpayment occurs, exploring options like payment plans or seeking professional tax advice is highly recommended to mitigate the impact of compounding interest and potential further penalties.
