Hello, Mattgdrum. Welcome to Community!
To set your tax rate in Alberta to 5% with your account integrated to Dext (and syncing to QuickBooks), follow these steps:
- First, go to the Sales Tax section from the left-hand menu. Then click "Manage sales tax".

- Select "Add Tax" and choose "Canada Revenue Agency" as the tax agency.
- Next, since Alberta only has the 5% GST and no PST or HST, create a new tax called "Alberta GST" and set the rate to 5%.

- After that, log in to your Dext account and access the integrations settings.
Map the Alberta GST tax within Dext to the 5% GST tax you set up in QuickBooks.
Finally, create a sample transaction in Dext and verify that the 5% GST applies correctly in QuickBooks after syncing.
If you encounter any issues, review your tax settings in the Dext integration and make any necessary adjustments.
