If i pay my freight forwarder $5000 and $3000 of it is gst, how do i write this in quickbooks to get the $3000 to come off what i owe in the gst section?

I might have a way in entering this in QuickBooks Online, frayedknots.

When you create the expense transaction, you can enter the item (freight forwarder) twice. Then, make sure the amounts and tax rates are correct. Here's my example:

1. Click Create (+) menu at the top and select Expense or Cheque.
2. Enter the Payee, Bank account, Pay date, and Cheque number.
3. Go to the the Item details section and enter the item twice.
4. Make sure each line item has the correct amount and tax rate.
     • First line is taxable worth 3000.00.
     • Second line isn't taxable worth 2000.00.
5. Review the details and click Save and close.
   

Though that's how I think it is, I'd still recommend reaching out to accounting professionals. They know what's the best way to enter it.

I'll be right here if you have additional questions.
