Now, a word on timing. The IRS loves to play games with postmarks. If you mail your payment on April 15th, but the postmark is after 5 PM local time, they’ll treat it like you paid on April 16th—and you’ll owe a late fee. Yes, the post office actually timestamps your envelope like a bouncer checking IDs at a nightclub. So get it in early, or use certified mail and get a receipt. That receipt is your legal shield against angry IRS letters.
Surprising fact: the IRS processes over 200 million paper tax returns and payments each year. That’s enough paper to wrap Earth in receipts. But here’s the joke: they also lose about 3% of mailed payments annually. That’s like losing your car keys in a swimming pool—and then blaming the pool. So if you don’t get a “thank you” letter (IRS Form 6478, “We Got Your Money”), you might need to call. Good luck with that phone hold music.
What If You Send It to the Wrong Place?
Relax, you won’t go to federal prison (probably). If you send your check to the wrong IRS office, they’ll shuffle it around like a confused postman on his first day. But it could take 6 to 8 weeks to process, during which time you’ll get late notices from the IRS that smell like panic and regret. So don’t be that person. Double-check the address, and maybe add a little prayer to the envelope gods.

Also, never send cash through the mail. I know, I know—you’re old-school and trust the postal service. But the IRS warns that cash is “high risk” and recommends checks or money orders. Think of it this way: mailing cash is like throwing twenties into a wind tunnel while wearing a blindfold. Write a check made payable to “United States Treasury”—that will make you feel official and slightly violated.
