How to add custom duty/excise in bill (inventory purchase) so that it becomes part of the cost of inventory?

Hi info-smuccivapes,

Greetings and thank you for joining the QuickBooks Community! We appreciate your interest in learning how to include duty or excise taxes on your inventory purchases. Allow me to guide you through the process of inputting these taxes on your transactions.

In order to add the mentioned taxes into your inventory purchases, you have the option to combine it to the main tax of your purchases. Basically, you will add a new tax rate for the duty/excise, and then create group tax composed of the original sales tax and the newly created duty/excise tax.

Create a new tax rate for the duty or excise tax.

1. Go to the Taxes section in QuickBooks.
2. Select Add Tax.
3. Enter the tax name and rate for duty or excise tax.
4. Select Purchases and enter a rate.
5.  click Save.

Next, create a group tax that combines the original sales tax and the newly created duty or excise tax.

1. Go to the Taxes section again and select Add tax.
2. Choose Group rate.
3. Select the original tax and the duty/excise tax on accordingly.
4. Give the group tax a name, like Combined rates.

In the group tax settings, add both the original sales tax and the newly created duty or excise tax. This will merge them into a single tax rate. Save the group tax and apply it to your inventory purchases. When recording a transaction, choose the group tax you created instead of the individual taxes.

If you have any other concerns, please don't hesitate to reach back out. I'm just around to help.

Consider having a 3rd party inventory management app with that feature to integrate with QBO.
