I recently changed bank accounts, now when I try and link the new account I get an error. I know it's because the business tab has to be selected on the bank website.

I want to ensure you're able to change your bank account, quintin1.

Before proceeding, may I know the exact error you've encountered? This helps me further investigate the main cause of this.

If you can't find your account, there are several reasons this can happen. I've listed them below.

• Your bank has multiple names on our list. Make sure you have selected the correct listing or have tried all possible links. 
• Your bank does not connect to all types of accounts (for example, personal accounts vs business accounts).
• Your bank is not a participating financial institution.

To resolve this, I'd suggest checking out this article: Lookup Your Bank When you Connect it to Online Banking.

In the meantime, use the WebConnect feature to import transactions and then download them into your company file. The Manually upload transactions into QuickBooks Online link will walk through the step-by-step process.

In case you encounter any errors, please see this article which contains a list of common online banking errors: What to Do if You See a Bank Error or Bank Transactions Won’t Download.
