How can I delete my surplus account? there does not seem to be a delete account function

Hello there.

Allow me to clarify things and share some additional information about managing accounts in QuickBooks Online (QBO).

In QBO, we only make accounts that are no longer in use or inactive rather than deleting them so you still have access to past transaction data for reporting purposes.

Before making an account inactive, please be informed of the following:

• You cannot permanently delete an account, except for merging an account into another.
• Transactions associated with an inactive account stay intact.
• If you want to make necessary edits to transactions associated with an inactive account, you'll need to reactivate the account first.
• Before making a balance sheet account inactive, correct the balance to zero first. If the balance isn't zero, QBO automatically makes an adjustment entry to zero it out. The automatic entry will then be posted to the Opening Balance Equity account, which is the equivalent of posting to previous years. The entry could potentially cause incorrect tax info to be filed.

Also, there are certain accounts in QuickBooks that can't be deleted because they are default accounts. And certain accounts require extra steps before you can make them inactive. 

When ready to make the account inactive, follow the steps below:

1. Go to the Gear ⚙ icon and select Chart of accounts.
2. Find the account you want to delete.
3. Click on the Action ▼ dropdown and select Make Inactive.

Additionally, since the account is only inactive, it'll still display on your reports for accuracy. With this, I've included an article that'll help you customize reports so you have the option to hide inactive accounts and personalise your reports with the data you only want to see: Customise reports in QuickBooks Online.

Please keep us posted if you have additional questions about managing accounts in QBO. It's our priority to guide you all the way. Have a good one.
