The IRS may owe you an additional refund if you received unemployment benefits in 2020 and paid taxes on the benefits. Under the American Rescue Plan Act, a $10,200 tax exemption was added that gives you a tax break on the unemployment benefits you received. The new stimulus bill also gives you more weeks of the bonus $300 payments, a third stimulus check and expanded child tax credit payments.

The IRS said it will automatically refund money to eligible people who had already filed their tax returns before the unemployment tax break changes went into effect.

23 million Americans filed for unemployment in 2020 due to the coronavirus pandemic, according to the Bureau of Labor Statistics. Under the Pandemic Unemployment Assistance created under the CARES Act in March 2020, this included those who were laid off as well as gig workers, contractors and self-employed people who don’t normally qualify for unemployment insurance. Here’s what we know about the unemployment tax refund right now, and the details we’re still waiting to learn.

“This new clarification from the IRS is good news for the millions of taxpayers impacted, but may still be confusing,” said Mark Steber, chief tax officer for Jackson Hewitt. “Some taxpayers may have questions as to the timing of any payment and whether it will come in a check or other form. The IRS is still providing clarification on these and other questions related to the just announced program. Once taxpayers receive their automatic payments in the coming weeks and months it may be a good idea to check in with a trusted tax pro to make sure the IRS computed their amount correctly.”
