To update your business address with the IRS and your state, file IRS Form 8822-B (or simply use the new address on your next business tax return) and file the address-change form your state’s Secretary of State requires for your entity type. Those two filings are the core of the job. After that, you’ll need to touch state tax accounts, any local licenses, and your mail forwarding so nothing important lands at the old address during the weeks agencies take to catch up.
What to Have Ready Before You File
Pull these together first so you can complete both filings in one sitting:
- Your Employer Identification Number.
- The exact address the IRS and your state currently have on file.
- Your new physical address and, if different, your new mailing address.
- Your business name exactly as it appears on your most recent tax return. A small mismatch can delay processing.
The IRS form is Form 8822-B, “Change of Address or Responsible Party — Business,” available on the IRS website. Your state form depends on your entity type and jurisdiction. Most states use a Statement of Information, a Statement of Change of Registered Office, or a Certificate of Amendment filed through the Secretary of State’s office. Check your state’s business filing portal to confirm which one applies to you before you start.
How to Update Your Address with the IRS
Option 1: File Form 8822-B
Form 8822-B notifies the IRS of a new business mailing address, a new business location, or a change in the responsible party. One important distinction: filing this form for an address-only change is voluntary, and the IRS won’t penalize you for skipping it. The 60-day filing deadline printed on the form applies only to responsible-party changes, not to address changes. Voluntary doesn’t mean safe to ignore, though. If the IRS sends a notice of deficiency or a demand for payment to your old address and you never see it, penalties and interest keep growing regardless.1Internal Revenue Service. Form 8822-B (Rev. December 2019) Change of Address or Responsible Party – Business
The form asks for your EIN, old address, new address, a daytime phone number, and the signature of the responsible party or an authorized representative. If your responsible party has also changed, that section becomes mandatory and carries the 60-day deadline.
Mail the completed form to one of two IRS service centers based on where your business is located: Kansas City, MO 64999 for most Northeast, Mid-Atlantic, Midwest, and Southeast states, or Ogden, UT 84201 for most Southern, Western, and Plains states. The Form 8822-B instructions include the full state-by-state list.2Internal Revenue Service. Where to File Form 8822-B
Processing generally takes four to six weeks. For employment tax address changes, the IRS sends confirmation notices (Notice 148A and 148B) to both the old and new addresses to verify the change is legitimate.3Internal Revenue Service. Address Changes
Option 2: Update Through Your Next Tax Return
If your next business return is due soon, you can skip Form 8822-B for the address change and just file the return with the new address. The IRS treats the address on your most recently filed return as your current address on record.3Internal Revenue Service. Address Changes This works for Form 1120, Form 1065, Form 1040 Schedule C, and other business returns. The trade-off is timing. If the return isn’t due for months, you’re exposed during the gap.
Sole Proprietors: Pick the Right Form
If you’re a sole proprietor with an EIN, use Form 8822-B like any other business.4Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business If you operate under your Social Security number and never applied for an EIN, use Form 8822 (the individual version) instead. Filing the wrong one won’t update the right account.
Updating with Your State’s Secretary of State
Every state requires businesses to keep a current address on file with the Secretary of State or equivalent agency. That record is how courts and government agencies know where to deliver lawsuits, subpoenas, and other legal documents through service of process. If your address is outdated and you miss a summons, a court can enter a default judgment against your business, meaning you lose the case without ever getting a chance to respond.
Most states keep track of two separate addresses, and people often confuse them:
- Your principal office address, where the business actually operates or where its main records are kept. Updated through a Statement of Information, annual report, or Certificate of Amendment depending on the state.
- Your registered agent address, where legal documents can be served during normal business hours. This cannot be a P.O. box or a virtual mailbox. It’s updated through a dedicated change-of-registered-agent form.
If you use a commercial registered agent service, the registered agent address may not change when your business moves, but your principal office address still needs updating. Filing fees for state address amendments generally range from about $25 to $70, though they vary by state and entity type. Most states offer online filing through the Secretary of State’s website, which often processes faster than paper.
State Tax Accounts, Licenses, and Permits
Updating with the Secretary of State does not automatically update your records with other state and local agencies. If your business collects sales tax, update your address with the state department of revenue or taxation separately. The same goes for state income tax withholding and unemployment insurance accounts. Each is typically its own system with its own update process, usually through the state revenue department’s online portal.
Local business licenses and operating permits need attention too. Many municipalities tie licenses to a specific address because of zoning rules, so a move across town can require a new license rather than an update to the existing one. Skipping this step can lead to fines or a temporary suspension of your right to operate. Your city or county clerk’s office can tell you what applies.
If You’re Moving to a Different State
An in-state move is mostly paperwork. A move across state lines opens a much longer list because the new state has no record of your business.
Once you establish a physical presence in the new state, most states require you to register as a foreign entity and obtain a certificate of authority before conducting business there. Operating without that registration can result in fines, back taxes for the unregistered period, and losing the right to bring lawsuits in that state’s courts. Foreign qualification fees vary widely, with most falling between $50 and several hundred dollars.
A cross-state move also triggers other obligations. Register with the new state’s revenue and labor departments for income tax withholding and unemployment insurance. Notify your workers’ compensation insurer and confirm coverage for employees in the new state; some states run their own funds and require separate enrollment. If you collect sales tax, get a new permit in the destination state. And check whether any professional licenses you hold need a state-specific version, since some don’t transfer.
If you’re fully leaving the original state, you may also need to file a withdrawal or dissolution with that state’s Secretary of State so annual report fees and franchise taxes stop accruing.
Forwarding Your Mail During the Transition
Mail sent before your changes are processed will still arrive at the old address. USPS offers Premium Forwarding Service Commercial for businesses, which temporarily reroutes all mail from the old address to the new one. You can choose daily, weekly, or monthly forwarding, with each reshipment costing $26.40 on top of an enrollment fee.5USPS. Manage Your Business Mail The standard free USPS change-of-address service also works for businesses and forwards first-class mail for up to one year, though packages and some mail classes are handled differently.
IRS processing alone runs four to six weeks, and state agencies vary. Setting up mail forwarding the same day you submit your filings gives you the best chance of not missing anything important in the gap.
What Happens If You Don’t Update
The consequences aren’t dramatic on day one, but they compound. The IRS won’t fine you for having an outdated address, but it will keep sending legally significant notices to the address on file, and those notices are treated as delivered whether you actually receive them or not. Miss a notice of deficiency and you lose your window to challenge a proposed tax increase in Tax Court. Miss a demand for payment and interest and penalties keep growing.1Internal Revenue Service. Form 8822-B (Rev. December 2019) Change of Address or Responsible Party – Business
At the state level, an outdated address can put your business out of good standing. States require periodic filings (annual reports, Statements of Information) that get mailed to the address on record. Miss those and your entity can be administratively dissolved or suspended, which strips the liability protection that comes with an LLC or corporation. Reinstating a dissolved entity costs more and takes longer than simply keeping the address current.
The most overlooked risk is service of process. If someone sues your business and the summons is delivered to an address you abandoned, a court can grant a default judgment for the full amount the plaintiff requested without you ever appearing. Unwinding a default judgment after the fact is possible but expensive and far from guaranteed. Keeping your registered agent address current is the single most important step to avoid that outcome.
