Saying they're the IRS, they're convincing, but  don't fall for it

Received this call today saying that they are the IRS and that the IRS is filing a lawsuit against me.  Of course I did not provide any information.  The IRS does not contact people this way.  Do not talk with them.

I received a call today telling me to call 425-296-6679 that the IRS is filing a lawsuit.  I called from a different phone and a man with a indian accent answered.  He only wanted to talk to my husband.  And wanted to know what number was called because my number did not match.  I asked how late they are open he said 7:30 pm.  The IRS office does not stay open that late.  The phone number is a Kirtland WA number

want to know that this is real irs or what please help me
