Can You Earn 7% Interest from the IRS? How Tax Refund Interest Really Works in 2026

Have you ever heard someone say:

“If you overpay your taxes, the IRS may pay you interest when it gives the money back.”

It sounds surprising, but it is true.

For the third quarter of 2026, from July 1 through September 30, the IRS overpayment interest rate for individuals is 7% per year.

Even more interesting, IRS interest is generally compounded daily.

And on August 21, 2026, the IRS announced that the rate for individuals will remain at 7% for the fourth quarter of 2026, covering October 1 through December 31.

When you compare 7% with the yields currently available from high-yield savings accounts, Treasury bills, and other relatively safe places to hold cash, an obvious question comes to mind:

“Why not intentionally overpay my taxes and earn 7% from the IRS?”

Unfortunately, it does not work that way.

You generally cannot use the IRS as a 7% savings account.

The reason is that IRS overpayment interest is governed by much more than the headline interest rate.

You also need to understand when interest begins, the 45-day rule, and when various tax payments are legally treated as having been paid.

So let’s look at when the IRS actually pays interest on tax refunds, when that 7% begins to accrue, whether intentionally overpaying your taxes can make you money, and how IRS interest differs from savings accounts and Treasury bills.

Yes, the IRS Really Can Pay Interest on Your Tax Refund

Suppose your total federal income tax liability for the year is $30,000.

But between:

• Federal income tax withholding
• Estimated tax payments

you paid a total of $50,000.

That leaves you with:

$50,000 − $30,000 = $20,000

of overpayment.

Normally, that $20,000 would be returned to you as a federal tax refund.

But if the IRS holds the overpayment long enough under circumstances that qualify for interest, the IRS may also owe you overpayment interest under Internal Revenue Code Section 6611.

In other words, you could eventually receive:

$20,000 Tax Refund + IRS Overpayment Interest

The refund is simply your own money being returned to you.

The interest is a separate amount paid because the IRS held the qualifying overpayment for a period covered by the tax-law interest rules.

The IRS Overpayment Interest Rate Is 7% in 2026

For individuals, the IRS overpayment interest rate for the third quarter of 2026 is:

7% per year

The IRS has also announced that the individual rate will remain at 7% for the fourth quarter of 2026.

IRS interest is generally compounded daily.

That sounds attractive.

For example, if we simplify the calculation and assume that a 7% annual rate applied continuously to a $20,000 overpayment for six months, daily compounding would produce roughly $712 of interest.

If $50,000 earned 7% for an entire 365-day period, the interest would be roughly $3,625.

Looking only at those numbers, IRS interest sounds like a very attractive return.

But there is an important catch:

IRS interest rates are adjusted quarterly.

A 7% rate today does not mean you are guaranteed 7% for the next 12 months.

More importantly, having an overpayment does not necessarily mean you will receive interest at all.

---

So Can You Intentionally Overpay Your Taxes and Earn 7%?

This is probably the most important question.

Imagine that your actual federal tax liability is only $30,000.

But you intentionally pay $80,000, creating a $50,000 refund.

You might think:

“If the IRS pays 7% on overpayments, why not create a $50,000 refund and earn interest on it?”

The problem is that this does not function as a reliable investment strategy.

One major reason is the IRS 45-day rule.

Under IRC Section 6611, when a timely filed income tax return shows an overpayment, the IRS generally has a 45-day administrative period in which it can issue the refund without paying interest on that overpayment.

For a late-filed return, the relevant 45-day period generally runs from the filing date.

So this could happen:

Intentionally overpay by $50,000
↓
File Form 1040
↓
IRS processes the refund within the applicable 45-day period
↓
You receive your $50,000 back
↓
IRS interest: generally $0

You have not earned 7%.

You have simply allowed the federal government to temporarily hold $50,000 of your cash without paying you interest.

Even More Important: Interest Does Not Automatically Start When You Send Money to the IRS

This is one of the most commonly misunderstood parts of IRS overpayment interest.

The system does not generally work like this:

Send money to the IRS today → immediately start earning 7%

The starting date for overpayment interest depends on the applicable tax rules and circumstances.

Depending on the situation, relevant dates can include:

• The statutory due date of the tax return
• The filing date of a late-filed return
• The date the IRS receives a processable return
• The applicable payment date

Withholding and estimated tax payments are especially important because they are subject to special statutory timing rules.

Under IRC Sections 6513 and 6611, federal income tax withholding and estimated income tax payments are generally treated, for relevant overpayment-interest purposes, as paid on the due date of the income tax return rather than simply on the dates the money actually left your paycheck or bank account.

That distinction is critical.

For example, you generally cannot do this:

Pay an extra $50,000 of estimated tax in December 2026
↓
Earn 7% from the IRS until April 2027

The estimated tax payment does not simply begin earning IRS overpayment interest from the December payment date.

For these purposes, the statutory payment-date rules generally treat estimated income tax differently.

In other words:

Sending money to the IRS earlier does not turn the IRS into a high-yield savings account where your interest clock starts immediately.

---

If the IRS Takes More Than 45 Days, Does Interest Start Only on Day 46?

This is another area where the rules are easy to misunderstand.

When people hear about the 45-day rule, they may imagine something like this:

Days 1–45: 0% interest
Day 46 onward: 7% interest

That is not necessarily how the calculation works.

For a timely filed return, if the refund is not issued within the applicable 45-day period, IRS guidance explains that interest may generally be calculated from the return’s due date, subject to the applicable statutory rules.

For a late-filed return, the filing date can become the relevant starting point.

Other factors—such as the payment date and when the IRS receives a processable return—can also affect the actual interest computation.

So it would also be misleading to summarize the rule as:

“You earn 7% only on the days after the first 45 days.”

The 45-day rule is essentially an administrative grace period, not necessarily the beginning date of the interest calculation once the IRS exceeds that period.

---

IRS Overpayment Interest Is Not an Investment Product

Once you understand these rules, the nature of IRS overpayment interest becomes much clearer.

It is not:

“A government program where taxpayers can deposit excess cash and earn a high yield.”

It is better understood as:

Interest the government may owe when it holds a taxpayer’s overpayment long enough for the statutory interest rules to apply.

The IRS explains that it generally pays interest when taxpayers overpay their taxes, but the tax code also provides rules such as the 45-day administrative period.

That is why I would not recommend looking at the current 7% IRS rate and thinking:

“I should move some of my cash to the IRS.”

The IRS is not a savings account.

---

IRS Refund Interest Is Taxable

There is another important catch.

Interest paid to you by the IRS is generally taxable interest income for federal income tax purposes.

Suppose the IRS pays you:

$1,000 of refund interest

That does not mean you have $1,000 of after-tax profit.

If, purely for illustration, your federal marginal tax rate were 24%, then:

$1,000 × (1 − 24%) = $760

would remain after considering only that assumed federal income tax.

Depending on your circumstances, other taxes may also need to be considered.

If you receive sufficient taxable interest from the IRS, you may receive Form 1099-INT.

But even if you do not receive a Form 1099-INT, taxable interest generally still must be reported when required.

So whenever you see the IRS’s “7%” rate, remember:

Look at the after-tax return—not just the headline rate.

---

Comparing IRS Interest with Treasury Bills Requires Looking at Taxes Too

This becomes especially interesting for people living in states with income taxes, such as New Jersey or New York.

Interest from U.S. Treasury obligations such as Treasury bills is subject to federal income tax but is generally exempt from state and local income taxes.

IRS overpayment interest, however, is not interest from a U.S. Treasury security.

So simply comparing:

IRS: 7%
vs.
T-Bill: 3%–4% range

can be misleading.

Taxes are only one difference.

The much bigger distinction is this:

A Treasury bill is an investment that you can intentionally purchase.

IRS overpayment interest, on the other hand:

Arises only when the requirements of the tax law are satisfied.

So rather than thinking of the IRS’s 7% rate as an investment return competing with Treasury securities, it makes more sense to think of IRS overpayment interest as:

Interest you may be entitled to when the government holds your tax overpayment for an extended period.

---

If a Large Refund Has Been Delayed, Check the Interest

This is where IRS overpayment interest becomes genuinely important from a tax-planning and compliance perspective.

Suppose you have:

• A large federal tax refund
• A lengthy IRS processing delay
• An amended return
• A refund resulting from an examination
• A significant overpayment caused by withholding or estimated tax payments

Depending on the circumstances, the interest associated with the refund could become meaningful.

So when a long-delayed refund finally arrives, do not necessarily assume:

“The refund arrived, so everything is finished.”

It may be worth checking:

Was the IRS overpayment interest calculated correctly?

For a small refund delayed only briefly, this may not matter much.

For a large refund delayed for many months—or even years—the amount can become significant.

---

What If You Think the IRS Paid Too Little Interest?

If you believe the IRS did not pay the full amount of overpayment interest you were entitled to receive, there may be ways to request additional interest.

Depending on the circumstances, the IRS provides procedures that can include:

• An informal claim
• Form 843, Claim for Refund and Request for Abatement

IRS guidance generally provides a six-year period from the date of the scheduled overpayment for certain claims involving additional overpayment interest.

However, Form 843 is not simply a form where you write:

“My refund was late. Please pay me more interest.”

A proper claim may require analyzing items such as:

• The applicable overpayment date
• The interest starting date
• The refund date
• Relevant payment dates
• Applicable quarterly interest rates
• The IRS’s original interest computation

Because the IRS interest rate can change from quarter to quarter, a long-running interest calculation may involve several different rates.

---

So What Should You Do with Extra Cash Instead?

Suppose you know that you will eventually owe federal estimated taxes.

Should you simply send the money to the IRS months early?

Usually, there is little reason to intentionally make a very large tax payment significantly earlier than necessary solely because the IRS overpayment rate happens to be high.

You still need to make estimated tax payments when required and satisfy the applicable estimated-tax rules and safe harbors.

But cash that does not yet need to be paid to the IRS can generally be evaluated alongside ordinary cash-management alternatives such as:

• High-yield savings accounts
• Treasury bills
• Money market funds

Conceptually, the strategy is:

Excess cash
↓
Keep it appropriately liquid while earning a return
↓
Make required estimated tax payments by the applicable deadlines

This does not mean:

“Invest the tax money and simply pay the IRS late.”

Failing to make sufficient estimated tax payments when required can result in an underpayment of estimated tax penalty, even if you ultimately pay your full tax balance when filing your return.

The objective is to avoid unnecessarily giving up control of your cash while still satisfying your tax-payment obligations.

---

You Can Also Apply an Overpayment to Next Year’s Estimated Tax

When your tax return shows an overpayment, you generally have another option besides requesting a refund.

You can elect to apply some or all of the overpayment toward your next year’s estimated tax.

This can be useful for taxpayers who expect to owe estimated taxes anyway.

However, this does not create a way to continue earning the IRS’s 7% overpayment interest rate.

Under IRC Section 6513, an overpayment credited toward the following year’s estimated tax is treated under the rules applicable to the next year’s income tax payments.

So this strategy does not work:

Leave the refund with the IRS → continue earning 7% indefinitely

IRS overpayment interest and an election to credit an overpayment toward next year’s estimated tax operate under different tax rules.

---

Bottom Line: The IRS’s 7% Rate Is Attractive—but It Is Not a Savings Account

As of August 2026, the IRS overpayment interest rate for individuals is:

7% per year

That rate applies during the third quarter of 2026, and the IRS has announced that it will remain at 7% for the fourth quarter.

Interest is generally compounded daily.

At first glance, that looks extremely attractive compared with many low-risk cash-management alternatives.

But this strategy does not work:

Intentionally overpay the IRS
↓
Earn 7%
↓
Request a refund and collect the profit

Why?

Because:

• The IRS has a 45-day administrative rule
• IRS interest rates are adjusted quarterly
• Interest does not simply begin when you send the money
• Withholding and estimated taxes have special statutory payment-date rules
• A quickly processed refund may generate no interest
• IRS interest itself is generally taxable income

So the most useful lesson is not:

“How can I create a refund so the IRS pays me interest?”

It is:

“If the IRS held a large overpayment for a long time, did it pay me all the interest I was legally entitled to receive?”

You should not create a tax refund just to try to earn IRS interest.

Instead:

Make sure you do not leave legitimate IRS overpayment interest on the table.

That is the much more practical—and potentially valuable—way to think about the IRS’s 7% interest rate.
