The government is warning taxpayers about a large-scale scam.
More than 20,000 people have been targeted.
As a part of the scam fake IRS agents call people claiming they owe taxes.
They then demand payment by prepaid debit card or wire transfer.
If people refuse to do so, the scammer will threaten them with arrest, deportation or loss of a business or driver's license.
Alabama's IRS Representative Dan Boone says the IRS agents usually contact you by mail.
He also says real IRS agents don't demand immediate payment by debit, credit card or wire transfers.
"These scammers very often know information about you, like the last four digits of your social security number, where you work, or they have your address. So if someone calls and has information about you, don't let that fool you into thinking it is really is the IRS," Boone said.
