I would like to delete QB online accountant i signed in by mistake. How can i do that?

Hi there, @affinitymcanvas-.

I want to officially welcome you to the Community space. It's my pleasure to help you delete your QuickBooks Online Accountant.

If you set up yourself as an accountant using the same email address with your regular account, you can't remove it unless you transfer the Master Administrator of the account. You can transfer it to your accountant or create a dummy email account and add it as a new member in your QuickBooks Online Accountant (QBOA) account. Once done, log in to your QBOA account as a Master Administrator. Then, follow these steps to transfer its role:

1. Select Team under Your Practice.
2. Click the user that reads Master Admin in the Access column.
3. In the Edit user screen, select the Firm Administration and Books tab.
4. Select Transfer Master Admin.
5. From the user selection drop-down, choose the user to which you wish to transfer the Master Administrator role.
6. Click Send invitation.

This will send an email invitation to the user. Once accepted, the role of Master Administrator will be transferred. You can now login back to your QBO account and remove the accountant from there. 

However, if you're still unable to remove your accountant's profile, I'd suggest contacting our Customer Support Team. They have tools that can check your account securely and cancel the accountant's subscription.

Here's how:

1. Go to the Help icon, then choose the Talk to a human option (then type it again when prompted).
2. When asked by the bot, type in a short description of your concern.
3. Select I still need a human.
4. Proceed with Contact us.
5. Type your concern in the description box and hit Let's talk.
6. Choose the Start a chat button.
7. Type in your contact info.
8. Select Confirm my call.

Please call our support within business hours to guarantee we address your problem promptly. 

In case you want to subscribe to a new QBO account, you can use a different email address and username password. If you use the same email and password upon signing up the accountant's profile will still show up.  

For complete details about subscribing to QBO, please see this link: How to resubscribe or reactivate QuickBooks Online.

Also, I recommend visiting this website: Resource Hub. It provides you articles about managing your QBO account, income, expenses, banking, inventory, taxes, and running reports. Just click + More topics under Topics to expand the sections.
