Is this call really from the IRS?
You can't tell from caller ID alone: scammers routinely make a real IRS number show up on your screen. The safe move is to hang up and call the IRS back on a number from the table above (or from the back of your card or an official letter), never on a number the caller gives you.
What the IRS says about how it contacts you
- The IRS normally contacts you the first time by letter, sent by the US Postal Service. (irs.gov)
- A call, email or text that is unexpected, rushes you, threatens you, asks for personal or financial information, or demands payment now is not from the IRS. A social media direct message never is. (irs.gov)
Treat these as red flags whoever the caller claims to be: pressure to act right now, threats of arrest, deportation or a frozen account, requests for gift cards, crypto or a wire transfer, and any request for a one-time passcode, PIN or full password.
