  • The standard non-corporate interest rate is 3% plus the federal short-term rate with variations for corporations, depending on the amount of the underpayment/overpayment.

How IRS Interest Rates Are Determined and Applied

The IRS determines interest rates quarterly according to Internal Revenue Code Section 6621. If you wanted to express IRS interest rates as a formula it would look like this: [Quarterly rate] + [Federal short-term rate] = IRS interest rate.

The rates announced on Nov. 23 are based on the federal short-term rate (0.22%) that took effect on November 1, 2021. IRS interest rates are compounded daily whether for overpayment or for underpayment.

Changes to IRS interest rates do not affect interest rates charged or paid in prior quarters or years.

The tables below show the exact rates for both underpayment and overpayment for the quarter beginning Jan. 1, 2022.

When Overpayment or Underpayment Interest Applies

You may be wondering where your interest payments are for all the years you had too much withheld from your salary or paid higher-than-necessary estimated taxes. Unfortunately, overwithholding or paying too much in estimated taxes alone does not generate interest. In fact, you've likely heard various tax experts warn against overwithholding because you are, in essence, lending the government your money at zero interest.

Any interest you receive from the IRS is considered taxable and must be reported on your tax return the following year.

Overpayment of Taxes

If the IRS is late in getting your refund to you, the government is required to pay you interest starting on whichever of the following dates is the latest:

  • Tax return filing date [+45 days]
  • Late-filed return received date [+45 days]
  • Date an incomplete or erroneous return is corrected and filed [+45 days]
  • Date the overpayment is made [+45 days]

The IRS has 45 days to issue your refund without paying interest on it.

Underpayment of Taxes

The IRS charges interest on underpayment if you don't pay by the filing due date. This applies even if you file an extension. In addition to interest, there are also separate penalties that may apply. Penalties vary depending on the type of underpayment and other factors and include Failure to File, Failure to Pay, and Accuracy-related issues. Interest, which is compounded daily, is due as it accrues. If you receive an underpayment notice you have until the "pay by" date to settle up and avoid interest charges.

Special Rules for COVID-19

Many taxpayers whose 2019 returns showed refunds also received interest due to late payments from the IRS. Although the regular April 15 filing deadline was postponed to July 15, 2020, interest in these cases accrued from the original April 15 filing deadline. The interest rate applied even to taxpayers who waited until July 15 to file. In addition, the normal 45-day administrative delay was waived.

What is the IRS underpayment interest rate for 2022?

3% plus the federal short-term rate (0.22%) for a total rate of 3.22% for most filers. The IRS sets interest rates on a quarterly basis. There are separate rates for corporations, depending on the amount of underpayment.

Will the IRS pay me interest if I overpay on my taxes?

In most cases, no. The IRS will pay interest if it is late in paying your refund. Late is defined as more than 45 days after the filing due date in most cases.

How Are IRS Interest Rates Compounded?

Interest rates charged or paid by the IRS are compounded daily, meaning each day the interest is calculated on the previous day's balance plus interest.
