You can switch business bank accounts, but the process takes planning because your vendors and customers need the new details
Switching business bank accounts is possible and happens regularly—companies change banks for lower fees, better service, or a merger. The catch is that money and information flow through your old account, so you need to move those flows deliberately rather than just opening a new account and hoping things sort themselves out. The actual switch typically takes two to four weeks once you start, but planning should begin at least a month before.
The core steps are: open the new account, set up a transition period where both accounts run in parallel, notify everyone who sends or receives money from you, move your recurring payments and deposits, and close the old account once everything has cleared. What makes this harder than it sounds is that some vendors move slowly, some payments take days to process, and you need proof that old transactions cleared before you close the account.
Key Takeaways
- Open your new account at least four weeks before you plan to close the old one, because you will need time to notify vendors and redirect payments.
- Run both accounts in parallel for at least two weeks after you have notified everyone, so you can catch payments that were sent to the old account by mistake.
- Notify customers, vendors, payroll processors, and loan servicers of the new account details in writing, and ask them to confirm receipt.
- read and save three months of statements from your old account before closing it, because you may need them for tax records or disputes.
- Close the old account only after all pending transactions have cleared and you have confirmed the final balance is zero.
What to do before you open the new account
Before you contact your new bank, make a list of everyone who touches your money: customers who pay you by ACH or check, vendors you pay regularly, your payroll processor, your accountant, loan servicers, and any government agencies that send you refunds or payments. Include the frequency—weekly, monthly, quarterly—because you will need to know how long to keep both accounts open.
Gather your business documents. You will need your EIN, articles of incorporation or formation, business license, and a recent business tax return. Different banks ask for different documents, so call ahead and ask what they require. If you have a business line of credit or merchant services with your current bank, ask whether those move with you or whether you need to set them up separately at the new bank.
Check your current account for automatic payments you may have forgotten about. Log into your online banking and look for recurring transfers, bill pay transactions, and ACH debits. Many small business owners discover subscriptions or vendor payments they had not thought about in years. Write these down—you will need to update them at the new bank.
Opening the new account and setting up parallel banking
Once you have chosen your new bank, open the account. The bank will give you a new routing number and account number. Write these down and keep them separate from the account itself—you will be giving them to many people. Ask the bank how long it takes for the account to be fully active and for you to be able to receive ACH deposits and make ACH payments. Some banks set up accounts within one business day; others take three to five.
Do not close your old account yet. Instead, set a date—usually two to four weeks out—when you will close it. This is your transition window. During this time, both accounts will be open and active. Money may still arrive at the old account, and you need to be able to see it and move it if necessary.
Set up your new account's bill pay and ACH capabilities as soon as the bank confirms they are active. Make a test transaction—pay yourself a small amount or transfer a few dollars from the old account to the new one—to make sure the routing and account numbers are correct. A typo here costs you time and money.
Notifying customers, vendors, and service providers
Send written notice of your account change to everyone on your list. Email is acceptable, but include the new routing number and account number clearly, and ask them to confirm they received it. For vendors you pay by check, you do not need to notify them—checks will still work. For vendors you pay by ACH, you must notify them, because ACH payments are tied to specific account numbers.
For customers who pay you, send the notice at least three weeks before your transition date. Include language like: "Effective [date], please send all payments to our new account: [routing number] [account number]. Please update your records. If you have any questions, contact us at [your phone number]." Ask them to confirm they have updated their systems.
Notify your payroll processor separately and in writing. Payroll is time-sensitive, and a missed payroll deposit can create serious problems. Give the processor at least two weeks' notice and confirm that they have updated your account information before your next pay run. If you use direct deposit for employee paychecks, this is critical.
For loan servicers, credit card processors, and government agencies, send notice by mail or through their online portal if one exists. These organizations move slowly, so give them extra time. Keep copies of everything you send and any confirmation they send back.
Moving recurring payments and deposits
Once your new account is active, set up all your recurring payments at the new bank. This includes vendor payments, loan payments, insurance premiums, and any subscription services. Most banks let you set these up through their bill pay system or through ACH. Do this at least one week before your transition date so you can test them.
For payments that are currently set up at your old bank, do not delete them yet. Instead, let them run one more time from the old account, then cancel them. This way you can see that the payment went through and you have a record of it. Then set up the same payment at the new bank for the next cycle.
For deposits, you do not need to do anything on your end—customers will send money to the new account once they have updated their records. However, during your transition window, some customers will still send money to the old account by mistake. You will need to monitor the old account and move that money to the new account manually, or ask your old bank to forward it.
What to do during the transition window
For two to four weeks after you have notified everyone, check both accounts daily. Look for deposits or payments that arrived at the wrong account. If money lands in the old account, transfer it to the new account when ready. If a vendor sends a payment to the old account, contact them and ask them to resend it to the new account, or transfer it yourself if the vendor is not responsive.
Keep a straightforward log: date, transaction, amount, which account it hit, and whether you moved it. This log is your proof that you managed the transition carefully, and you will need it if there is ever a dispute about whether a payment was made.
Continue to monitor your old account for at least one full billing cycle after your last known payment was due. Some vendors batch payments and send them days or weeks later. You do not want to close the account and then discover that a check or ACH payment bounced because the account was closed.
Downloading records and closing the old account
Before you close the old account, read and save at least three months of statements—ideally six to twelve months. Save them as PDFs on your computer and back them up to cloud storage. You will need these for tax records, and you may need them to prove a transaction happened if there is ever a dispute.
Contact your old bank and tell them you want to close the account. Ask them to confirm that the balance is zero and that there are no pending transactions. Some banks will not close an account if there is even a small balance or a pending check. If there is a balance, transfer it to the new account. If there is a pending check, wait for it to clear or ask the issuer to reissue it to the new account.
Once the account is closed, ask the bank to send you written confirmation. Keep this confirmation with your records. Some banks charge a fee to close an account early; ask about this before you close.
What to do if something goes wrong
If a payment bounces because it was sent to the old account after you closed it, contact the vendor when ready and ask them to resend it to the new account. Most vendors will do this without complaint if you explain what happened. If the payment was a loan or tax payment, contact the recipient and explain the situation—they may waive a late fee if you can show that you closed the account in good faith and the payment was sent to the old account.
If you discover that a customer or vendor never received your notification, send it again when ready and ask them to update their records. If they claim they never got the first notice, send it by a method that requires confirmation—certified mail, or email with read receipt.
If you cannot find a vendor or customer to notify them of the change, keep trying for at least 30 days. If they send a payment to the old account after that, your old bank may return it or hold it. Contact the old bank and ask what their procedure is for returned payments to closed accounts. Some banks will forward mail to your new address; others will not.
Frequently Asked Questions
Can I keep my old account open indefinitely while I transition?
Technically yes, but it is not a good idea. An open account costs money in fees, and the longer it stays open, the more likely you are to forget about it and miss a payment or deposit. Most banks recommend closing within 30 to 60 days of opening the new account. If you have a vendor you cannot reach, keep the old account open for 90 days, then close it.
What if my bank charges a fee to close the account early?
Ask the bank what the fee is before you close. If it is more than a few dollars, ask whether they will waive it if you explain you are switching to another bank. Some banks will waive the fee if you ask. If they will not, pay it—it is usually cheaper than the cost of a missed payment or a bounced check.
Do I need to notify the IRS or my state tax agency about the account change?
No. The IRS and state agencies do not need to know which bank account you use. However, if you have a payment plan or an installment agreement with the IRS, contact them to update your account information so future payments go to the new account. You can do this through the IRS website or by calling the number on your notice.
What if I have checks printed with the old account number?
You can still use them during the transition window, but order new checks with the new account number as soon as possible. Old checks will work as long as the account is open, but once you close it, any checks that have not cleared will bounce. For this reason, try to use up old checks before your transition date, or ask your bank to hold the account open a few extra weeks while old checks clear.
How long does it take for ACH payments to show up in the new account?
ACH transfers typically take one to two business days. So if a customer sends a payment on a Monday, it should arrive by Wednesday. During your transition window, check your new account daily so you can catch deposits as they arrive and confirm they are correct.
