Okay, so you’ve found the address. But what are you actually mailing? If you’re sending a check or money order, make it payable to the “United States Treasury.” And for the love of all that is holy, include your Social Security number and the tax year on the memo line. Otherwise, the IRS might just cash your check and wonder who the heck sent it—then bill you again.
Here’s the ironic part: the IRS will happily take your check, but they really prefer you pay online. It’s faster, and you avoid the whole “did it get lost in the mail?” anxiety. But if you’re a paper-and-stamp traditionalist (or just terrified of online security), mailing it works. Just use certified mail with return receipt. Trust me on this. Nothing says “I paid you” like a tracking number.

What About Refunds? Different Story.
If you’re getting money back (lucky you), you don’t need to mail anything. Just hit “e-file” and let the IRS direct deposit your refund. No stamp, no envelope, no worries. But if you sent a paper return anyway, mail that to the same address based on your state—but check the chart first, because some states send refund returns to different boxes.
