So, here's your to-do list. Find your EIN confirmation letter. Download Form 8822-B. Fill it out with your neatest handwriting (or type it—they love that). Mail it to the address in the instructions. Not the general IRS address. The specific one for your state.
Then, pour yourself a celebratory beverage. You did it. You told the tax man where you live. It's not romantic, but it's adulting at its finest. Now go unpack those boxes.
You've got this. And if you mess it up? Eh. Just send another form. The IRS loves second chances. They just call them "amended returns." But that's a story for another coffee chat.
