Welcome to the Community, @accounts-viney-c.
I understand how important it is to enter transactions correctly into your QuickBooks Online account. Let me share with you the steps on how to enter customs tax.
- From the Edit menu, choose Preferences.
- On the Preferences window, select Sales Tax then go to the Company Preferences tab.
- Click the Add sales tax item button.
- In the Type drop-down, select Sales Tax Item.
- Enter the tax name, rate, and select your tax agency.
- Click OK.
When you set up VAT, QuickBooks Online automatically sets up a list of common VAT codes for you.
The Community Team is always here for your question with VAT setup.
