Hi Rinjolync,
First thanks for sharing detail with example. Its quite understandable.
But please note that the amount of Bill is 110, while we have to pay 100 AED to the supplier. So, how this (tax of 10 AED) will be subtracted from total amount to have net amount of 100 AED. Further "paying the tax amount to the respective tax agency will be done out of QBO" is not understandable.
Regards,
Abdul Rehman.
It's good to have you back, Abdul Rehman.
We have another recommendation and this is to create a liability account. This way, we can keep track of the balance due from the supplier's bill, and the tax amount deducted on their behalf. Here's how:
- Click Accounting on the left panel, and then select Chart of Accounts.
- Click the New button.
- From the Account Type drop-down, select Current liabilities.
- From the Detail Type drop-down, select Other current liabilities.
- In the Name field, enter "Tax on supplier's behalf".
- Click Save and close.
Afterwards, you can edit the bill and enter a negative amount in the Tax on supplier's behalf.
You can refer to the screenshot for your guide:

You also need to create an Expense transaction to pay the portion of the tax on the supplier's behalf to the tax authority.
Please see attached screenshot:
I'd still recommend reaching out to your accountant on what account to use for proper recording.
Just let me know if you have any other questions on this. I'd be glad to help.
