A business change of address letter is a short written notice on company letterhead that tells an agency, bank, insurer, vendor, or other contact that your company has moved. At minimum it needs your legal business name, your old address, your new physical and mailing addresses, the effective date of the move, any updated phone or email, a clear request to update the recipient’s records, and the signature of an authorized officer, owner, or manager. Everything else is packaging.
The letter itself is the easy part. The harder part is knowing who has to receive one, which government forms travel alongside it, and how to prove you sent it if the notice is ever questioned.
What Belongs in the Letter
The same basic template works whether you are writing to the IRS, a landlord, a supplier, or your bank. Include:
- Your company’s legal name as filed with the state, not a shortened trade name.
- The date of the letter, which establishes when notice was given.
- The recipient’s name and address, personalized to a specific contact where possible.
- Your old address, so the recipient can locate your account in their records.
- Your new physical address and your new mailing address. If you use a P.O. Box for mail, list both.
- The effective date of the move, so the recipient knows when to start using the new address.
- Any updated phone numbers or email addresses that changed along with the location.
- An explicit request to update all accounts, billing records, and correspondence files.
- The signature of an authorized person. Some agencies reject notices signed by someone without authority to bind the company.
Keep the tone professional and brief. The recipient only needs the data. Do not explain why you moved or describe the new space. Print on letterhead, sign it, and keep a copy before sending.

Who Needs to Receive One
The list is longer than most owners expect. Work through it in order of urgency.
Federal Agencies
The IRS comes first, and here the letter is replaced by a form. File Form 8822-B to update your business mailing address, physical location, or both.1Internal Revenue Service. Form 8822-B – Change of Address or Responsible Party — Business The form covers all your federal tax accounts, including employment tax returns like Forms 940 and 941, and must be signed by an authorized officer, owner, partner, or LLC member-manager.2Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business You do not need a new EIN because of an address change or a move to a different state; you keep the existing number.3Internal Revenue Service. When to Get a New EIN
If your business holds federal contracts, update your physical and mailing addresses in SAM.gov. Changes become visible within 24 hours, and the system generates an eMod modification request that you have to log in and approve. Save the SF-30 it creates as your record.4Vendor Support Center. Updating Your Company Headquarters Address
If you own registered trademarks or have pending applications, update your address with the USPTO through the Trademark Electronic Application System. There is no hard deadline, but if the USPTO cannot reach you, a missed office action or maintenance filing can cost you the registration.5United States Patent and Trademark Office. Apply Online
State Agencies
Your state’s Secretary of State keeps the public record of your business registration. Depending on your entity type, you may file an amendment to your articles of incorporation or organization, or use a simpler address-change form. Most states accept these filings online, and fees typically run from nothing up to around $140. Each state has its own procedure for updating organizing documents, and any state-level license tied to the old address also needs updating.6U.S. Small Business Administration. Have an Address Change for Your Business? Here’s Who You Need to Inform
Do not forget your state Department of Revenue. A sales tax permit is tied to a physical location, and selling from a new address without updating your registration creates compliance problems. If you have employees, your state unemployment insurance account also needs the new address.
Your Registered Agent
If you use a registered agent service, notify it so legal documents get forwarded to the right place. If you serve as your own registered agent and the registered office address is changing, file an update with the Secretary of State. This is the highest-stakes item on the list. Lawsuits are served at the registered agent address, and if a complaint is delivered to an outdated address and you never see it, the court can enter a default judgment with no chance to defend.
Local Government
City and county licensing offices generally require you to update your business license or operating permit after a move. Many jurisdictions set a 30-day deadline and charge late fees. Rules vary a lot between municipalities, so contact the local licensing office directly.
Banks, Insurers, and Private Partners
Banks use your address to spot fraud. Transactions originating from a new location that does not match the address on file can freeze cards or flag wire transfers. Update the bank before you start operating from the new location, not after something gets flagged.
Insurance companies price general liability, property, and workers’ compensation based on where you operate. Moving without notifying your insurer risks a claim denial because the policy was priced for a different location. Most commercial policies require prompt notification of address changes as a condition of coverage.
Vendors, logistics partners, and any company that ships to you need advance notice. For key suppliers, a phone call followed by a written confirmation works better than a letter alone. Arrange utility service at the new address to overlap the old by a few days so nothing goes dark during the transition.
Set Up USPS Mail Forwarding as a Backstop
Filing a change of address with the U.S. Postal Service catches mail from senders you forgot. You can submit online at usps.com for a $1.25 identity verification fee, and forwarding usually starts within a few business days.7United States Postal Service. Standard Forward Mail and Change of Address First-class mail, Priority Mail, and periodicals forward at no extra charge. USPS Marketing Mail (the bulk advertising category, which can include some legitimate business correspondence from senders using bulk rates) is not forwarded at all. Treat USPS forwarding as a safety net, not a substitute for direct notice.
How to Send Notice and Prove You Sent It
Documentation is the reason most of these letters exist. For government filings on paper, send by USPS Certified Mail with Return Receipt. As of 2025, Certified Mail costs $5.30 and a hard-copy return receipt adds $4.40 (an electronic return receipt is $2.82). That $8 to $10 buys a timestamped record that the agency received your filing.
For state filings submitted online, save a PDF or screenshot of the confirmation page the moment you submit. Do not rely on an email arriving later. If the portal shows a transaction number, download the receipt on the spot.
For private-party letters, email with a read receipt is usually enough. If a contract requires written notice at a specific address (commercial leases often do), follow the method the contract specifies. When in doubt, send both an email and a hard copy.
A few weeks later, verify the updates took. Check your state’s Secretary of State business search to confirm the public record shows the new address. Watch bank statements and insurance declarations for the update. For the IRS, the next piece of correspondence will tell you whether the change went through.
A Cross-State Move Is More Than a Letter
An in-state move is mostly paperwork. A move across state lines is a bigger legal event that a change of address letter alone will not handle. You will generally either domesticate the entity into the new state (if both states allow it), or form a new entity there and register as a foreign entity or wind down the original one. In the old state, file a certificate of withdrawal (also called cancellation or surrender, depending on the state) to end your registration formally, or you will keep owing annual report fees and possibly franchise taxes there. Some states require tax clearance before accepting the withdrawal, so build in time. If any employees stay behind and work remotely, your business may still have tax nexus in the old state after the physical office moves.
What Happens If You Skip the Notifications
- Missed IRS notices. The IRS mails to the address on file. A notice of deficiency sent to your old address still starts the clock, and penalties and interest accrue whether you see it or not. You can lose the right to contest an assessment in Tax Court because the statutory deadline passed.
- Default judgments. Courts have consistently held that failing to maintain a current registered agent address is not a reasonable excuse. A plaintiff can obtain a judgment against your business without you ever knowing about the lawsuit.
- Loss of good standing. Many states mark entities as delinquent or administratively dissolve them when official mail bounces. Losing good standing can block you from signing contracts, borrowing, or filing suit in the company’s name until you pay reinstatement fees.
- Insurance claim denials. A policy priced for one address may not cover losses at another. Insurers have contractual grounds to deny claims when a material change in risk was not reported.
- Disrupted cash flow. Tax refund checks, client payments, and vendor credits mailed to the wrong address delay collections for weeks.
Every one of these is more expensive to fix than to prevent. Start your notifications two to four weeks before the move so processing times do not leave a window where nobody can reach you.
