To change the address on your sales tax permit, log into your state Department of Revenue’s online tax portal, open your account or registration details, and update the business location; if your state still uses paper, file its business change form instead. Save the confirmation, then update the tax rate you collect and notify the other agencies that hold your address separately.
What to Have Ready Before You Start
Pull these together first so you can finish in one sitting:
- Your Federal Employer Identification Number (EIN), the nine-digit number the IRS assigns to your business entity.1Internal Revenue Service. Get an Employer Identification Number
- Your state sales tax account number, which appears on your original permit or on previous tax filings.
- The full new address, including any suite or unit number.
- The effective date of the move, so the state can assign the correct tax rates starting on the right day.
If your state doesn’t handle changes online, look on its Department of Revenue website for a form with a name like “Notice of Business Change” or “Account Maintenance Form.”
How to Submit the Update
Most states now handle this through an online tax account portal. Log in, go to your account settings or registration details, and edit the business address directly. Some portals let you make the change in the system without uploading anything. Others require you to complete a change form and upload it. Either way, save the confirmation screen or receipt the system generates.
If your state still accepts paper submissions, mail the completed form to the processing address listed in its instructions. Certified mail with return receipt gives you proof the agency received it. Paper submissions take longer to process than electronic ones, and during that window you should keep checking your online account to confirm the change goes through.
Address Change or New Permit?
One detail trips people up. In many states, each physical business location needs its own permit rather than an updated address on the old one. Before you file anything, check whether your state treats a move as a simple address update or requires you to register the new location separately. Some states issue a new permit with the same tax identification number for the new location. Others assign a fresh number altogether. Getting this wrong means you could be operating at the new location without proper authorization.
Update the Tax Rate You Collect on the Same Day
Sales tax rates aren’t set only at the state level. Counties, cities, and special taxing districts each layer on their own rates, so moving across town can change what you owe. A business relocating from one side of a metro area to the other might see its combined rate shift by a full percentage point or more.
Once your address update takes effect, you’re responsible for collecting tax at the rate that applies to your new location. Keep charging the old rate and you’ll either shortchange the state and owe the difference later or overcharge your customers. Update your point-of-sale system and any invoicing software on the same day the move becomes official. If you use a tax calculation service, verify that it pulls the correct rate for the new address.
Other Agencies You Also Have to Notify
Updating your address with the state tax agency does not update your records anywhere else. Work through this list in the days around your move:
- IRS. File Form 8822-B to report your new business mailing address or business location. The form is technically voluntary unless your responsible party has changed, but if the IRS can’t reach you with a notice, penalties and interest keep accruing whether you saw the notice or not.2Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party
- Secretary of State. If your business is a corporation, LLC, or partnership registered with your state’s Secretary of State, file a separate address amendment or change of registered office with that agency.
- Local licenses and permits. City or county business licenses, health permits, zoning approvals, and any industry-specific authorizations are all tied to a specific address. Contact each issuing agency directly to find out its update process.
- State employment agency. If you have employees, your state unemployment insurance account also needs the updated address.
A systematic pass through each agency prevents the situation where you get fined six months later by an office you forgot about.
If You’re Moving to Another State
An address update inside the same state is straightforward compared to a move across state lines. Sales tax permits are issued by individual states and have no portability, so you cannot change the address on your existing permit to one in another state.
Close Out the Old State
Cancel your permit in the state you’re leaving and file a final sales tax return. That final return covers all sales through your last day of business in the state, and it also includes details people miss. You generally must report and pay tax on any business assets sold as part of winding down, such as fixtures, equipment, or furniture. Inventory kept for personal use rather than resold is typically subject to use tax on the final return as well. Inventory sold to another retailer for resale usually isn’t taxable, but you’ll need a resale certificate from the buyer in your records.
Cancel the permit promptly. Leave the old account open and the state will keep expecting returns. Unfiled returns generate automated notices, then penalties, then potentially liens against your business, all at an address you’ve already left. Most states let you indicate on the final return itself that you’re closing the account.
Register in the New State
Once the old account is settled, apply for a new sales tax permit in your destination state. The application mirrors what you went through the first time: EIN, business structure details, expected sales volume, and the new business address. Most states don’t charge a fee for the permit itself, though a handful require a security deposit or bond depending on the type of business or your compliance history. Wait for the new permit to arrive before you start making taxable sales at the new location.
If you do business in multiple states, the Streamlined Sales Tax Registration System lets you register in all participating member states through a single online application.3Streamlined Sales Tax Governing Board. Sales Tax Registration SSTRS Returns are still filed and paid directly to each state.
You May Still Owe the Old State
Physically leaving a state doesn’t necessarily end your obligation to collect its sales tax. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, most states impose economic nexus rules that require out-of-state sellers to collect tax if they exceed certain sales thresholds in that state. If you relocate but continue selling into the old state above its threshold, you may still need to maintain a sales tax registration there. Closing your permit prematurely in that scenario puts you out of compliance.
What Happens If You Don’t Update
The most immediate risk is practical. Tax bills, audit notices, filing reminders, and compliance letters all get sent to the address on file. If those go unanswered, the state doesn’t shrug and try again. It proceeds as if you’ve been notified. Late filing penalties accumulate, and the state may suspend or revoke your permit after enough missed deadlines.
Operating without a valid permit is where the consequences get serious. Penalties vary by state but commonly include a flat fine for the first day of unauthorized sales activity plus an additional daily penalty for each subsequent day. Some states treat willful failure to maintain proper registration as a criminal offense, with potential fines and jail time. Those outcomes are reserved for cases that look like deliberate tax evasion, but the administrative penalties alone make the update worth doing right away. After you submit your change, look your business up in the state’s online permit lookup tool and confirm the new address appears correctly.
