Wait. Before you check that tax refund status or panic about a balance due, you need to look at one specific number. It’s the IRS current interest rate, and honestly, it’s a lot higher than most people realize. For the first quarter of 2026, the IRS has held the line. They aren't budging.
If you’re an individual taxpayer, you’re looking at 7% for both overpayments and underpayments. That’s a hefty chunk of change when you consider it’s compounded daily. Basically, the IRS is currently functioning like a high-yield savings account if they owe you—or a pesky credit card if you owe them.
Why the IRS Current Interest Rate Stayed Flat
The IRS doesn't just pull these numbers out of a hat. They follow a strict formula tied to the federal short-term rate. Every quarter, they look at what happened in the first month of the previous quarter. For this current Jan-March 2026 stretch, they used the data from October 2025.
Since the federal rate didn't see a wild swing, the IRS kept things steady. Here is the breakdown of what that looks like in the real world:
- 7% for individual underpayments (you owe them).
- 7% for individual overpayments (they owe you).
- 6% for corporate overpayments.
- 9% for large corporate underpayments.
See that last one? 9% is no joke. If a corporation misses a big payment, that interest stacks up so fast it can make your head spin. It’s calculated as the federal short-term rate plus 5 percentage points.
The Math Behind the "Daily Compounding" Trap
Most folks hear "7% per year" and think, "Okay, that's not great, but I can handle it." But here's the kicker: it’s compounded daily. This isn't your standard simple interest.

If you owe $10,000, you aren't just paying 7% on that ten grand. On day two, you're paying interest on the $10,000 plus the interest from day one. It’s a snowball effect. Over a few months, a manageable debt can balloon into a genuine problem.
I’ve seen taxpayers ignore a $2,000 bill thinking they’ll "get to it eventually." Six months later, with the IRS current interest rate at 7% and various failure-to-pay penalties tacked on, that $2,000 has grown a set of legs and run away.
A Quick Reality Check on Refunds
Now, some people get excited about the overpayment rate. "Hey, 7% is better than my bank!" Sorta. But the IRS doesn't start paying you interest the second you overpay. Generally, they have a 45-day grace period from the return due date or the date you filed (whichever is later) before they have to start cutting you a check for interest.
If you’re intentionally overpaying just to use the IRS as a piggy bank, you’re playing a risky game. You're better off putting that money in a brokerage account or a dedicated HYSA where you have actual control.

Different Rates for Different Folks
Not every tax debt is created equal. The IRS treats a small business differently than a massive corporation or a guy named Dave who forgot to report his gambling winnings.
For corporations, the overpayment rate is generally the federal short-term rate plus 2 percentage points. However, if that overpayment exceeds $10,000, the rate drops to 4.5%. This is often referred to as the GATT rate (named after the General Agreement on Tariffs and Trade).
On the flip side, "large" corporate underpayments (usually defined as exceeding $100,000) get hit with that 9% hammer. The IRS isn't subtle about wanting their money back from big fish.
What You Can Actually Do About It
If you’re staring at a bill and the IRS current interest rate is eating your lunch, you have options. You aren't just stuck.
- Pay what you can now. Interest is charged on the remaining balance. Every dollar you send today is a dollar that won't accrue interest tomorrow. Simple.
- Request an Installment Agreement. While this doesn't stop interest, it can sometimes reduce the failure-to-pay penalty from 0.5% to 0.25% per month. It's a small win, but you take what you can get.
- Check for "Ministerial Errors." Occasionally, the IRS messes up. If the interest accrued because an IRS employee was slow or made a mistake on a "ministerial act," you might be able to get that interest abated using Form 843. It’s rare, but it happens.
- The "First-Time Abate" Policy. This usually only applies to penalties, not the interest itself. However, if the penalty is removed, the interest on that penalty is also removed. It’s a backdoor way to lower the total bill.
Don't Count on Interest Abatement
Honestly, getting the IRS to waive interest is like trying to find a parking spot in downtown Manhattan on a Friday night. The law is very specific: the IRS must charge interest by statute. They don't have much "managerial discretion" to just say, "Oh, you're a nice person, let's forget the 7%."
The only way interest generally goes away is if the underlying tax or penalty is proven wrong. If you win an audit and your tax liability drops to zero, the interest disappears with it.

Actionable Next Steps
- Audit your 2025 withholdings immediately. If you're under-withheld, you're essentially taking a 7% loan from the government. You can probably find a better rate elsewhere.
- File even if you can't pay. The failure-to-file penalty is much harsher than the interest rate. Get the paperwork in to stop the 5% monthly penalty, then deal with the 7% interest later.
- Use the IRS Tax Withholding Estimator. It’s a boring tool, but it’s accurate. Adjust your W-4 so you're as close to "zero" as possible.
The IRS current interest rate is a reflection of the broader economy. As long as the Fed keeps rates up, the IRS will too. Keep an eye on the news in mid-February; that’s when they’ll likely announce the rates for Q2 2026. Until then, treat that 7% with the respect—and caution—it deserves.
