The IRS sends you a notice every time you sneeze, and those notices often list your Taxpayer ID. Look for any letter that starts with “Notice CP14” or “We have reviewed your account.” Yes, those are the ones you normally throw in the “to deal with later” pile—which is now a mountain in your closet.
Your bank might also have records. When you opened a checking account, they asked for your Taxpayer ID. Log into your online banking and look for “Account Details” or “Tax Forms.” It’s like a treasure map where X marks the spot… and the treasure is a 9-digit number.
Still can’t find it? Your state’s Department of Revenue might have it, especially if you’ve filed state taxes. Call them and pretend you’re calm. They’ll help, but expect to repeat your name, birthdate, and mother’s maiden name three times. It’s the dance we do.
