There isn't a direct way to auto populate GST, but you can add default sales and purchase tax to your products and services as a workaround. Here's how:
1. On the left menu bar, click on "Sales" then "Product & services"
2. Next, locate the item(s) you'd like to add the tax code to, then click edit under the Action column.
3. Scroll down until you see, "Purchase tax". Select the tax from the drop down menu that you want to add.
4. Hit "Save and close.
Note: You can also do the same for Sales tax by following the steps provided above.
If you'd like, you can also add a default tax code to your account in the Chart of accounts by following the steps below.
1. Head to the Transactions tab on the left menu, and click on "Chart of accounts"
2. Find the account you'd like to set the tax code to, click on the drop down arrow under the Action column and select "Edit.
3. At the bottom, you can chose the tax code from the drop down menu under "Default tax code"
4. Save and close when done.
Please feel free to reach back out with any other questions you may have. I'm here to help!
