Hi. How can I add gst to only 1 item in a split transaction? The remaining items are not taxable.

Hey office-karunia-c,

Thanks for reaching out to us here, and Welcome to the QuickBooks Community! Being able to add taxes correctly to your transactions in QuickBooks Online is an essential part in maintaining clean books. I can provide some information on how to add taxes.

When adding taxes to a split transaction, you're able to add the appropriate tax to the specific line item. Here's how :
1- Head to the Bookkeeping tab to the left of the page
2- In the Transaction section, click on Bank transactions
3- In the For review section, click on the transaction you'd like

4- Click on Split at the bottom right hand corner within the selected transaction
5- Select the appropriate tax for each line and complete filling out the required information
6- Click on Apply and accept.

If you have any other questions, feel free to reach out here.
