You cannot just write “The IRS, Anywhere, USA.” No, no. You must follow the sacred format. It looks like this: Internal Revenue Service, P.O. Box 802501, Cincinnati, OH 45280-2501. Yes, you need the hyphen at the end. The hyphen is critical. If you forget it, a dog in the mail room will eat your check. I made that up, but it feels true.

Write it in black ink. Use a blocky font. No fancy cursive. The machines scan your handwriting. Your messy cursive looks like ancient hieroglyphics to them. They will reject it, and the check will float in space forever.
Funny Details About the P.O. Box Life
Did you know the IRS gets more mail than Santa Claus at Christmas? Every April, mountains of envelopes pile up. They have special machines that sniff for checks. I imagine a robot yelling, “MONEY DETECTED!” as your envelope slides down a chute.
Also, you can mail your check with a stamp of a cat. The IRS clerks love cat stamps. They see a thousand boring flag stamps all day. Then they see a cat holding a knife. It makes them laugh. Your check might get processed faster out of sheer delight. Try it.
The Payment Slip is Not Optional
Do not just shove a check into an envelope. That is chaos. You must include the payment voucher (Form 1040-V). It’s a little slip of paper that tells the IRS: “This is for you, you beautiful bureaucracy.” Without it, they think you’re mailing them a love letter made of money.
They will open it, see a check, and get confused. They don’t like surprises. They like forms. They live for forms. Give them the form.
