If i need to make an adjustment in the output vat sales. Do i only use the amount that i need to add? or both amounts together

It's my goal to guide you on what amount to enter when creating a Value Added Tax (VAT) adjustment in QuickBooks Online (QBO), snaazysnaps.

Since you want to increase your VAT due, you only need to enter the amount you want to add, not the total output number. Then, ensure to select the appropriate expense account.

Here's a detailed step-by-step guide:

1. If you haven't yet, set up an expense account to categorise the VAT due increase.
2. Go to VAT and find the tax period to adjust. Then, click Prepare Return.
3. Select Adjust next to the entry.
4. Choose the Adjustment date and the Tax rate.
5. Select the expense account for the Adjustment account.
6. Enter the amount you want to add in the Adjustment amount.
7. Click Save.
