The basic steps to switch your business account

Moving a business bank account to a credit union takes four to six weeks and involves notifying your current bank, setting up the new account, and redirecting payments. You will need to gather account numbers, tax ID, and business documents, then update vendors and payroll systems to use your new credit union account details. The credit union will handle most of the heavy lifting once you open the account, but you are responsible for telling your current bank you are leaving and updating anyone who sends or receives money from you.

Start by opening the account at your credit union before you close anything at your current bank. This overlap period—usually two to four weeks—lets you test the new setup and catch problems before your old account is gone. During this time, you can run both accounts in parallel, which protects you if a payment bounces or a vendor sends money to the wrong place.

Key Takeaways

  • Open your credit union business account before closing your current bank account, and run both for two to four weeks to catch routing errors and missed payments.
  • You must manually notify vendors, customers, and payroll providers of your new account number and routing number—banks do not do this for you.
  • Automatic payments and direct deposits will fail if you do not update them, so prioritize payroll, loan payments, and recurring bills first.
  • Request a statement from your current bank showing all recurring transactions, because some vendors may not have a record of your account details.
  • Keep your old account open for at least 30 days after your last payment clears, in case a delayed check or ACH arrives.

Gather your documents and account information

Before you walk into the credit union, collect your business tax ID (EIN), articles of incorporation or LLC formation documents, and a recent business bank statement from your current account. The credit union will ask for these to verify you own the business and to see your transaction history. Bring a government-issued ID for each owner or authorized signer.

From your current bank account, write down every automatic payment and direct deposit that hits the account. Log into your online banking and look at the past 90 days of transactions—this shows you recurring charges you might have forgotten about. Note the vendor name, payment amount, and whether it is a debit (money going out) or credit (money coming in). Many businesses discover subscriptions or transfers they forgot they had set up.

Open the credit union business account

Contact your credit union and ask about business checking accounts. Credit unions often have different account types for sole proprietors, LLCs, and corporations, so tell them your business structure. Some credit unions require you to be a member first, which means opening a personal savings account and depositing a small amount (often $5 to $25). This takes one business day.

Once you are a member, apply for the business account. The credit union will ask for your business documents, tax ID, and identification. They will also run a background check and verify your business address. Approval usually takes one to three business days. Once approved, the credit union will give you your new account number and routing number—write these down and keep them somewhere safe, because you will need them dozens of times in the next few weeks.

Ask the credit union whether they offer account transfer services or ACH origination. Some credit unions can help you move recurring payments automatically, though this is less common than at large banks. Even if they cannot, ask them to walk you through their online banking system so you understand how to set up bill pay and view transactions.

Update automatic payments and direct deposits

This is the step that causes the most problems, because payments do not move automatically—you have to tell each vendor or payroll provider about your new account. Start with the ones that happen most often: payroll, loan payments, and utility bills. Contact each one and provide your new account number and routing number. Ask them to confirm the change in writing, either by email or by printing a confirmation from their website.

For payroll, log into your payroll provider (ADP, Gusto, QuickBooks Payroll, or whoever you use) and update the bank account information. Test it with a small manual payment before your next regular payroll run. For loan payments, call your lender directly—do not rely on online forms, because a mistake here can trigger a late fee or default. For utilities and other recurring bills, use their online portal if they have one, but follow up with a phone call to confirm the change was recorded.

For customers who send you money via ACH or check, update your invoices and website with your new account number. If you have a large customer who sends regular payments, call them directly and confirm they have updated their system. Checks take longer to clear anyway, so this is less urgent, but ACH payments will bounce if the account number is wrong.

Request a transfer of funds and close the old account

Once all your recurring payments and deposits have been moved to the credit union account, transfer any remaining balance from your old account. You can do this by writing a check to yourself and depositing it at the credit union, or by asking your current bank to wire the funds. A wire transfer costs $15 to $30 but arrives the same day; a check takes three to five business days but is free.

Wait at least 30 days after your last transaction clears before closing the old account. This protects you if a check you forgot about arrives late, or if a vendor is slow to process the account change and sends a payment to the old account. Once 30 days have passed and you have confirmed that no new transactions are hitting the old account, call your current bank and ask them to close it. They will ask if you want them to destroy your debit card and checks—say yes.

Request a final statement from your old bank showing the closure date. Keep this for your records, in case a payment arrives after closure and you need to prove when the account was closed.

Update your business records and tax documents

Update your business accounting software (QuickBooks, Xero, FreshBooks, or whatever you use) with the new account number. If you reconcile your bank account monthly, you will need to set up a new account in your software and link it to the credit union. Most accounting software lets you connect directly to your credit union's online banking, so transactions download automatically.

If you have a business line of credit, business loan, or merchant services account (for credit card processing), contact those providers and update your bank account information. Some lenders require a new account verification form, which the credit union can provide. Merchant services providers need your new account number so deposits go to the right place.

For tax purposes, keep a record of the switch date and the final balance in your old account. If you file quarterly estimated taxes or payroll taxes, make sure your tax payments are set up to go to the credit union account. The IRS and your state tax agency do not need to be notified of a bank account change, but your accountant or tax preparer should know about it.

Troubleshoot common problems during the switch

If a payment bounces because it went to your old account number, contact the vendor immediately and ask them to resubmit it to your new account. Most vendors will do this without charging a fee if you catch it quickly. If a customer's ACH payment bounces, contact them and ask them to try again—do not wait for them to notice the problem.

If your payroll fails to deposit on payday because the account information was not updated in time, contact your payroll provider and ask them to process an emergency payment to your new account. This usually takes a few hours. Notify your employees that there was a delay and that the payment is being reprocessed—do not let them find out by checking their bank balance.

If you discover a recurring charge you forgot about (a subscription, a vendor payment, or a loan payment), update it as soon as you find it. Check your old account for at least 60 days to catch anything you missed. If a charge hits the old account after you thought you had updated it, contact the vendor and ask them to reverse it and resubmit to the new account.

Frequently Asked Questions

Can I keep my old account open while I use the new one?

Yes, and you should. Run both accounts for at least two to four weeks so you can catch routing errors and missed payments before closing the old one. Keep the old account open for 30 days after your last transaction clears, in case a delayed check or ACH arrives. After 30 days with no activity, close it.

What if a vendor will not update my account information?

Ask them to confirm in writing that they have your new account details. If they refuse or say they cannot change it, ask to speak to their accounting or billing department. If they still will not update it, you may need to switch vendors or set up a separate account at your old bank just for that vendor until they can make the change.

How long does it take for direct deposits to start hitting the new account?

It depends on when the vendor processes the change. Most vendors update within one to three business days, but some take up to a week. Always test with a small payment first—ask your payroll provider to run a manual test deposit before your next regular payroll run. For customer payments, give vendors at least one week's notice before the payment is due.

Do I need to update my business license or tax documents?

No. Your business license and tax ID do not change when you switch banks. You do not need to notify the IRS, your state tax agency, or your local business licensing office. You only need to update vendors, customers, and payroll providers who send or receive money from you.

What happens if I close the old account too soon?

A payment that arrives after closure will bounce, and the vendor will be charged a fee. You will also be charged a fee by the credit union for the failed deposit. The vendor will then have to resubmit the payment to your new account, which delays the money reaching you. Wait at least 30 days after your last transaction before closing.
