If you've already filed your tax return, it's natural to wonder when you'll receive your refund. One of the most common questions is the exact time the IRS makes deposits.

STATEN ISLAND, N.Y. -- Tens of millions of Americans have already received tax refunds from the federal government, with the average return totaling more than $3,000, according to the latest Internal Revenue Service data.

Millions of Americans are eagerly awaiting their state tax refunds, but the process can vary significantly from state to state.

Through Feb. 21, the latest date currently available on the IRS website, the agency has issued 29,615,000 refunds, roughly 2.3% more than the 28,945,000 that had been issued by this time last year. The average refund amount through Feb. 21 was $3,453, roughly 7.5% higher than the average refund of $3,213 at that time last year.

The IRS has issued more than 29.6 million individual income tax refunds through Feb. 21, up 2.3% from a year ago.

As the April 15 filing deadline looms, the Internal Revenue Service reminds taxpayers that after three years, any unclaimed 2021 tax year refunds go to the U.S. Treasury.

In the United States, not every taxpayer will receive their tax refund as anticipated. Many may encounter reduced payments or, in some cases, no refund at all.
