The Internal Revenue Service may owe you money. But, if you want you refund, time is running out.

The IRS said nearly 1.5 million people are owed refunds totaling some $1.5 billion for tax year 2019. Included in those numbers are some 23,900 Alabamians who are owed some $23.7 million.

The average refund nationwide was $893. It’s slightly lower in Alabama – $880.

“Time is running out for more than a million people to get their tax refunds for 2019,” said IRS Commissioner Danny Werfel said in a statement. “Many people may have overlooked filing a 2019 tax return due to the pandemic. We don’t want people to miss their window to receive their refund. We encourage people to check their records and act quickly before the deadline.”

Under the law, taxpayers usually have three years to file and claim refunds. If they don’t file within the three years, the money becomes the property of the U.S. Treasury. Due to the COVID-19 pandemic emergency, the three-year window for 2019 unfiled returns was postponed by several months to July 17.

Even if you are owed a refund, there are things that could prevent you from receiving the money. A 2019 refund could be held if a taxpayer has not filed returns for 2020 and 2021, the IRS said. Also, the refund will be applied to any amounts still owed to the IRS or the state or used to offset unpaid child support or past due federal debts.
