While the second round of stimulus checks^[1] are still in limbo, a small category of taxpayers can anticipate getting some additional cash sometime soon, this time from the IRS.

According to a press release,^[2] nearly 14 million Americans will receive an interest payment check for their delayed tax refunds.

A long-standing law requires the IRS to pay interest to those who received their tax refunds late — notably 45 days after the typical filing date of April 15. Just as taxpayers must pay interest on any outstanding obligations they owe to the IRS, the rule works both ways if the IRS is late on the money they owe back.

With the onset of the coronavirus pandemic^[3] pushing back the filing deadline to July 15 this year, the IRS is paying interest calculated from the original April 15 filing deadline. The interest refund checks aren’t necessarily a big windfall of money in your pocket, but you can still make the most of the extra cash.

You will get an interest payment either directly deposited into your account or by paper check from the IRS for your late tax return if you:

• Filed a 2019 return by this year’s postponed deadline and received a tax refund after April 15
• Filed a 2019 return by this year’s postponed deadline and expect a refund soon

The IRS is only required to pay interest on late tax refunds to individual income tax filers, so businesses are not eligible. Those who receive the interest payment should keep in mind that they are considered taxable income. The money will be reported when you file your 2020 federal income tax return in spring of 2021.

If you qualify for an interest payment, prepare for it to be minimal. The IRS says^[4] that the average interest payment is about $18.

Though it’s not a big payout, something this small can grow to be much more if you stash it in the right place. Thanks to compound interest^[5], which is essentially earning interest on interest, you don’t need much money to get started saving.
