Change Of Address For Ein

So, picture this: My friend Dave—the kind of guy who files his taxes in January—moves his dog grooming business from a tiny garage to a legit storefront. He’s popping champagne, ordering business cards, the whole nine yards. A month later, the IRS sends his EIN confirmation letter to his old garage address. A stranger opens it. Dave spends four hours on hold with the IRS trying to explain he no longer lives above a brake shop. Ouch.

The secret nobody tells you about your EIN

Your Employer Identification Number—that nine-digit number you got when you started your biz—is basically your business’s social security number. And just like you can’t send your W-2 to your college dorm room, you can’t expect the IRS to telepathically know you’ve moved. The change of address for an EIN is a quiet, bureaucratic monster that people forget until they’re sobbing into a pile of late notices.

Here’s the kicker: the IRS doesn’t let you change the mailing address directly on your EIN record. Yeah, read that twice. You can’t just log in and type a new zip code. Feels a bit like the IRS is playing hard to get, right? Instead, you have to update your address via your business tax return (like Form 941 or 1120) or fill out Form 8822-B. It’s like they want you to prove you’re serious about moving.

The one weird trick (that’s actually the only trick)

If you’re a sole proprietor, just update your personal address with Form 8822. Your EIN follows your personal address automatically. It’s like magic, but slower. For LLCs, corporations, or partnerships? You’ve gotta file Form 8822-B (the business version). Don’t mix them up—the IRS loves sending paperwork back with a red stamp saying “WRONG FORM.” I’m only slightly kidding.

You can mail it in, but here’s the catch: it takes 4 to 6 weeks to process. In IRS time, that’s roughly a century. Want to speed things up? You can’t. No, they don’t accept faxes or emails for this. Welcome to 1995, my friend.

What about the “official” business address?

Here’s where it gets spicy. Your EIN is tied to the “responsible party’s” address—usually the owner. But the IRS also keeps a separate “mailing address” for correspondence. If you change your responsible party, you have to file Form 8822-B and possibly an updated SS-4. Yes, the same form you used to get the EIN in the first place. It’s paperwork inception.

Pro tip: If you use a registered agent or a virtual office, update that address with the IRS anyway. I once had a client who moved his LLC to a shared coworking space, but forgot to tell the IRS. They sent a penalty notice to the coworking space’s mailroom, where it got coffee-stained and buried under a pile of “free kombucha” flyers.

The “I forgot to update” tax bill special

Look, the IRS doesn’t send your penalty letters to your old address out of spite. They send them there because you never told them you moved. And then you get a late filing penalty, plus interest, and suddenly you’re on a payment plan for a mistake that took ten minutes to fix. Ten minutes. Set a recurring calendar reminder: every January, check your EIN address on the IRS’s “Business Tax Account” portal. Yes, it exists. No, it’s not glamorous.

If you’ve already moved and missed a letter? Call the IRS at 800-829-4933. Bring snacks, a good playlist, and your old address. They’ll verify your identity, then—miraculously—update the address over the phone. But only if you’re the responsible party. Have your EIN handy. And maybe a glass of wine.

The ironic reality check

Dave? He eventually got his EIN letter redirected. But he paid a $50 “rush fee” to a third-party service (scam alert—the IRS doesn’t offer rush services). Don’t be like Dave. The change of address for your EIN is free if you do it yourself. It’s just not fast.

So here’s my unsolicited advice: update your address the moment you sign a new lease. Before you celebrate. Before the business cards arrive. Because the IRS might not know where you live, but they definitely know where to send a bill.

Now go check that EIN address. I’ll wait. 🚚✉️
