I appreciate you sharing your situation regarding the transactions mistakenly posted from your old business account, @Olicrookes.
Since the transactions from your previous business account are already included in your VAT return, QuickBooks doesn't allow them to be uncategorized or removed directly. Instead, you can use a VAT adjustment to offset this.
Here's how:
Step 1: Set up an account for VAT adjustment
- Go to the Chart of Accounts and select New.
- Choose Income or Asset as the Account Type (to decrease VAT due).
- For Detail Type, select Sales of Product Income.
- Name the account clearly (for example: "VAT adjustment for Decrease)
- Click Save and Close.
Step 2: Add an adjustment
- Find the tax period you need to adjust, then select the Prepare return.
- Next to the VAT line you need to adjust, click Adjust.
- Select the adjustment account you created.
- Enter the adjustment amount and you can add a memo explaining the correction.
- Click Save.
This ensures your VAT return reflects the correct figures without needing to reverse the original transactions.
