The option to exclude VAT payable is unavailable even if the payment hasn’t been received yet, @mimi34.

Please note that the moment you create the sales tax, it’ll automatically be added to your liability or sales tax. Also, please note that even though you haven’t received the payment yet, the calculated tax will still show up in the taxable summary.

What you can do is adjust the VAT amount that you want to exclude when preparing the VAT return and making the payment. Here’s how:

1. Navigate to the left navigation panel and select VAT.
2. Find the VAT amount/name listed under Returns and click on Prepare Return.
3. On the VAT return page, locate the specific VAT entry and click Adjust.
4. Enter the adjusted amount as needed.
5. Once completed, click Save.
