You can change the name on your commercial account, but the process depends on your business structure and your bank
Yes, you can change your business name on a commercial checking account. The steps vary depending on whether you've legally changed your business name through your state (a formal name change) or straightforward want to operate under a different name (a DBA or "doing business as" registration). Your bank will need to see proof of the name change before they update your account, and some banks process this faster than others. The entire process typically takes one to three weeks.
The key difference is between a legal name change — where you file paperwork with your state and update your business registration — and a DBA registration, where you register a trade name without changing your official business structure. Your bank will ask for different documents depending on which one you've done.
Key Takeaways
- A legal name change requires filing amended articles with your state and updating your Employer Identification Number (EIN) with the IRS before your bank will change your account name.
- A DBA registration lets you operate under a different name without changing your legal business structure, and most banks will add it to your account once you show proof of registration.
- Your bank will need to see official documents — either an amended business certificate from your state or a DBA registration receipt — before processing any name change.
- You may need to close your old account and open a new one if your bank's system cannot link the old and new names, though many banks can transfer the account without closing it.
- Notify your payment processors, vendors, and customers of the name change separately — your bank's update does not automatically reach them.
Legal name change versus DBA: which one you have matters
A legal name change means you have filed amended articles of incorporation, articles of organization, or a certificate of amendment with your state's Secretary of State office. This changes your official business name in the state's records. If you did this, your bank will require a certified copy of the amendment or a letter from the Secretary of State showing the new name. You will also need to explore for a new EIN from the IRS if your business structure changed, or notify the IRS of the name change if the structure stayed the same.
A DBA (doing business as) registration is different. You keep your legal business name but register a trade name with your county or state. For example, your LLC might be called "Smith Consulting LLC" but you register a DBA to operate as "Smith Strategy Group." Most banks accept a DBA registration certificate or receipt from your county clerk's office. This is faster and cheaper than a legal name change, and you do not need a new EIN.
If you are unsure which one you have done, check your state's Secretary of State website or call your county clerk. They can tell you whether a legal name change or DBA is on file for your business.
What documents your bank will ask for
Bring one of these to your bank, depending on what you have done:
| Type of Name Change | Documents Your Bank Needs |
|---|---|
| Legal name change (LLC, corporation, partnership) | Certified copy of amended articles from your state Secretary of State, or a certified letter from the Secretary of State showing the new name. Some banks also ask for a copy of your new EIN letter from the IRS. |
| DBA registration | Original or certified copy of your DBA registration certificate from your county clerk or state office. A photocopy of the receipt is usually acceptable. |
| Sole proprietorship name change | DBA registration certificate. Sole proprietorships typically cannot do a legal name change — they register a DBA instead. |
Call your bank before you go in. Ask them specifically what they need — some banks have a checklist, and requirements vary slightly between institutions. A few banks ask for a letter from your accountant or lawyer confirming the name change, though this is less common.
The account update process and timeline
Once you bring in your documents, the bank will verify them and update your account. Most banks can do this in one to three business days if you are in a branch and the documents are in order. However, the full update — including new checks, debit cards, and online banking records — can take one to three weeks.
Ask your bank whether they will keep your account number and routing number the same. Most banks do, which means your direct deposits and automatic payments do not need to change. If your bank requires you to close the old account and open a new one (rare, but it happens), ask them to transfer any pending transactions and confirm the new account number before you leave.
In the meantime, your old checks and debit cards will still work, but they will have the old business name on them. You can use them, but it may confuse customers or vendors. Order new checks with the updated name once the bank confirms the change is complete in their system.
What happens if your bank cannot process the change
Some smaller banks or credit unions have older systems that cannot link an old account name to a new one. If this happens, the bank may require you to close the existing account and open a new one. This is inconvenient but manageable if you plan ahead.
Before closing, write down your current account number and routing number. Notify your employer (if you receive direct deposit), any vendors you pay by automatic transfer, and any customers who send you payments. Give them at least one week's notice of the new account number. Ask your bank to hold the old account open for 30 days after you open the new one, so any stray payments can still reach you.
If your bank insists on closing the account when ready, ask whether they can issue you a check for any remaining balance or transfer the funds electronically to your new account while you are there.
Updating your EIN and tax records
If you did a legal name change and your business structure stayed the same (for example, your LLC changed names but is still an LLC), you do not need a new EIN. However, you should notify the IRS of the name change by calling the IRS at 1-800-829-1040 or filing Form 8822-B (Change of Address). This keeps your tax records aligned with your bank account.
If your business structure changed (for example, you converted from a sole proprietorship to an LLC), you will need a new EIN. explore for one on the IRS website or by calling 1-800-829-4933. Once you have the new EIN, bring it to your bank along with your other documents.
If you only registered a DBA, your EIN does not change. The DBA is just a trade name, not a change to your legal business structure.
Notifying vendors, customers, and payment processors
Your bank's name change does not automatically notify anyone else. You will need to contact them separately. Start with the ones that matter most: your payment processor (Square, PayPal, Stripe, etc.), your merchant account provider, your accountant, and any vendors who invoice you or send you regular payments.
Send them a brief email with your old business name, new business name, and the effective date of the change. Include your account number if they ask for it. Ask them to update their records and confirm when the change is complete on their end. This usually takes a few days to a week.
Update your business website, social media, and email signature as well. If you have business cards or printed materials with the old name, you do not need to throw them away when ready, but order new ones with the updated name.
Frequently Asked Questions
Do I need to close my old account and open a new one?
Not usually. Most banks can update your account name without closing it, which means your account number and routing number stay the same. However, some smaller banks may require you to close the old account and open a new one. Ask your bank before you submit your documents.
What if I registered a DBA but my bank says they need a legal name change?
This is rare, but some banks have strict policies. If this happens, ask to speak with a manager and explain that a DBA is a valid trade name registration in your state. Bring a copy of your DBA certificate and your state's DBA statute if needed. If the bank still refuses, you may need to switch banks.
Can I change my business name without updating my bank account?
Technically yes, but it creates problems. Your bank account name should match your legal business name or registered DBA. If they do not match, customers and vendors may question the legitimacy of your business, and you may have trouble depositing checks made out to your new name. Update your account as soon as possible after your name change is official.
How long does it take to get new checks with my new business name?
Most banks can order new checks within one to two weeks. You can order them directly from your bank or from a third-party check printer, which is sometimes cheaper. Do not order checks until your bank confirms the name change is complete in their system.
What if I have a business loan or line of credit tied to this account?
Notify your lender of the name change at the same time you notify your bank. Bring the same documents you showed the bank. The lender will update their records to match. This does not affect your loan terms or balance — it is just a record update.
