If your business is based in Canada and connected to QuickBooks Online, Dext can extract and publish both GST/HST and PST/QST from your Cost items.
To do this, you must enable secondary tax extraction and select a combined default tax code.
Before you start
To configure Canadian secondary tax settings:
Your Base currency must be set to Canadian dollars
Your Account country must be set to Canada
Your account must be connected to QuickBooks Online
You can check your Base currency and Account country in:
Business settings > Business profile
Important:
Only Admin users can manage tax settings and QuickBooks Online connection settings in the account.
Accountants or bookkeepers accessing a client account act as Admin users by default.
Step 1: Turn on secondary tax extraction
Secondary tax extraction must be enabled for Dext to extract both GST and PST from Cost items.
Go to Business settings.
Select Extraction.
Open the Tax section.
Turn on Extract secondary tax.
This allows Dext to extract two tax amounts from eligible Cost items.
Step 2: Select a combined default tax code
After enabling secondary extraction, configure your default tax code in the QuickBooks Online connection settings.
Go to Business settings > Connections.
Select Manage next to QuickBooks Online.
Open Settings.
In the Tax tab, select one Default tax. This default tax must be a combined tax code, meaning it includes both:
GST/HST
PST/QST
For example, a GST/PST combined rate created in QuickBooks Online.
How the combined tax code works
When a combined default tax code is selected:
Dext extracts the total tax amount from the document
Dext assigns the correct GST and PST components automatically
QuickBooks Online records GST and PST separately
This ensures compliance with Canadian multi-rate tax requirements.
When to use line items
Use the Create line items feature if:
A document includes taxable and tax-free purchases
Different portions of the document require different tax rates
Additional taxes (such as liquor tax) are included
Line items allow you to split amounts and apply the correct tax code to each portion before publishing.
