To change your DBA address, file an amendment (or in some cases a fresh statement) with the same office that handled your original fictitious business name registration — usually a county clerk for sole proprietors and partnerships, or the Secretary of State for LLCs and corporations — and then update the IRS, your state tax accounts, licenses, insurance, and bank so the new address flows through every record tied to your business.
Find Out Where Your DBA Is Registered
The amendment has to go to whichever office holds your current registration. For sole proprietors and general partnerships, that’s almost always the county clerk or recorder where you first filed. LLCs and corporations usually file with the Secretary of State, though some states route entity-level fictitious names back to the county.
If you no longer have your original paperwork, pull up the online database for the county clerk or Secretary of State where you registered. Most offer free name searches that show your filing date, registration number, and the address currently on file. You’ll need all three to file the amendment.
Amendment or New Filing?
What you file depends on how far you’re moving.
Staying in the same county (or same state, for state-level registrations) is the easy case. You file an amendment to your existing registration, sometimes called an Amended Fictitious Business Name Statement or Amended DBA Certificate. The record stays intact; only the address changes.
Crossing county lines is harder. County-level DBA registrations typically only cover the county where they were filed, so a move to a new county often means your original registration no longer applies. Some states let you amend across counties; others require you to cancel the old registration and file a new statement in the new county. A new filing costs more than an amendment, and if your state requires newspaper publication, you’ll likely have to publish again.
Moving out of state adds another step for LLCs and corporations. If you were foreign qualified to do business in the old state, you’ll need to update that registration separately with the Secretary of State, or withdraw the foreign qualification if you’ve stopped operating there. That filing is independent of the DBA and carries its own fees.
What to Gather Before You File
Pull these together before you start the form:
- Your original registration number and filing date, both of which appear on your original certificate or receipt.
- Your business name exactly as registered — small differences like “and” versus “&” can get an amendment rejected.
- The current address on file, so the registrar can locate the right record.
- Your new physical address, and your mailing address if it’s different; some registrars treat these as separate fields.
- Government-issued ID or a notarized signature, if your jurisdiction requires one to verify you’re the registrant.
It’s also worth confirming with your city or county planning department that your new address is zoned for the kind of business you run, especially if you’re moving to a home-based setup or into a mixed-use property.
Your Registered Agent Address Is Separate
If you operate as an LLC or corporation, changing your business address doesn’t update your registered agent address, and the reverse is also true. The registered agent address is where legal documents like lawsuit notifications get delivered. It has to be a physical street address in the state where you’re registered, with someone available during business hours to accept service. If you serve as your own registered agent at your business address, both records need to be updated. If you use a professional registered agent service, their address stays put when you move.
Filing the Amendment
Most registrars take amendments online, by mail, or in person. Online portals are usually the fastest and generate an immediate confirmation. If you file by mail, use certified mail so you have delivery tracking. In-person filing lets staff flag errors on the spot.
Fees vary by jurisdiction and entity type. County-level DBA amendments commonly run $10 to $60. State-level filings for LLCs and corporations tend to cost more. Processing times also vary: online submissions often clear within a few business days, while mailed forms can take several weeks. Expedited processing is available in some offices for an extra fee.
When the registrar approves the amendment, you’ll get back a stamped copy or an official certificate. Keep it. Banks, insurers, and licensing agencies will ask for it as proof of the change.
Newspaper Publication
Several states require you to publish your DBA statement in a local newspaper after a change, the same way you may have had to when you first registered. The requirement is typically a legal notice running once a week for four consecutive weeks in an approved newspaper in your county, and publication usually has to start within 30 to 45 days of the filing.
Costs generally fall between $30 and $150, depending on the newspaper. If your original filing required publication, assume your amendment will too, and ask the registrar for the list of approved newspapers.
Notify the IRS
Your DBA is a state or local record. The IRS keeps its own address linked to your Employer Identification Number (EIN), and you update it with Form 8822-B, Change of Address or Responsible Party.
Filing the form for an address change is technically voluntary and the IRS won’t penalize you for skipping it. The practical problem is that if the IRS doesn’t have your current address, notices of tax deficiencies and demands for payment may never reach you, and penalties and interest will keep accruing all the same.1Internal Revenue Service.

One related rule: if the business has also changed its “responsible party” — the person who controls or manages the entity’s finances — filing Form 8822-B within 60 days is mandatory, not optional.1Internal Revenue Service. Form 8822-B, Change of Address or Responsible Party Processing generally takes four to six weeks.
A moving business does not need a new EIN. The IRS is clear that a change in name or location alone never requires a new EIN, whatever your entity type.2Internal Revenue Service. When to Get a New EIN Your existing number travels with you.
Other Agencies and Accounts to Update
The DBA amendment and IRS notification are the two biggest filings, but a business address shows up in a lot of other records. Work through them systematically.
State Tax Accounts
If you collect sales tax, your state tax authority needs the new address. The same goes for state payroll tax and unemployment insurance if you have employees. Most states let you update this through the same portal where you file returns. Do it as soon as the move is official so that correspondence, audit notices, and refunds reach you.
Banks and Financial Institutions
Your bank will usually want the stamped amendment or certificate before updating business checking accounts and credit lines. An address mismatch between your DBA filing and your bank records can trigger fraud alerts, delay transactions, and cause problems with payment processors. Bring the official document to a branch or upload it through the business portal.
Professional and Trade Licenses
Industry licenses and permits tied to your location need updating too. Many licensing boards require notification within a set number of days after a change, and missing the window can bring fines or a temporary suspension. Check each licensing authority’s specific process; some accept online changes, others want a written form.
Insurance Providers
Commercial insurance premiums are partly based on location, so a move can shift your rates in either direction, and a change in square footage or property type can affect your coverage limits. Notify your insurer promptly. Operating from an unreported address can give the insurer grounds to deny a claim.
Federal Trademark Records
If you own a federally registered trademark, the USPTO keeps a separate address record for the owner. You can update it through the TEAS Change of Address or Representation form at no charge.3United States Patent and Trademark Office. Personal Information in Trademark Records Keeping it current means renewal notices and any communications about challenges to your mark actually reach you.
USPS Mail Forwarding
Set up mail forwarding with the Postal Service as a safety net. Business mail forwarding typically runs for 12 months, which gives you time to update records without losing correspondence. File the request early; forwarding can take up to two weeks to start. USPS forwarding is not a substitute for formal address changes with government agencies — it just keeps the mail moving while you work the checklist.
What Happens If You Don’t Update
Delaying these updates creates problems that stack on top of each other. Your DBA is the public record linking your business name to a real person at a real address. If a lawsuit or legal notice is sent to that address and you’re no longer there, the court may still treat you as properly served, and a case can move forward without you knowing. The IRS and state tax agencies will keep sending notices to the old address, and missed deadlines don’t pause for misdirected mail.
Administrative consequences vary by jurisdiction and can include late-filing penalties running from $50 to several hundred dollars, involuntary cancellation of your DBA, or a lapse in your right to operate under that name. Cleaning up after the fact almost always costs more than handling the updates on time.
