Common Mistakes to Avoid in Canadian Tax Setup

Mistake	Explanation
Incorrect Tax Zone Configuration	Assigning the wrong province codes or regions breaks tax logic. Magento uses zones to calculate GST, PST, or HST. A mismatch triggers incorrect totals at checkout. Always match each tax zone with its exact provincial need. Use Canada’s tax structure as your reference.
Missing Tax Class Assignments	Skipping the product or customer tax class assignment leads to broken tax rules. Magento uses these classes to apply the right tax rate. Missing assignments result in untaxed taxed orders. Assign each product and customer group a valid class. Link these classes to your tax rules.
Wrong Calculation Settings	Choosing incorrect options under Tax Calculation Method causes pricing issues. For Canadian stores, set the method to Total and apply tax on Custom Price (if available). These settings ensure accurate pricing logic. Check all values under Calculation Settings. Make sure they support your pricing strategy.
Ignoring Display Settings	Failing to configure tax display fields creates confusion. Buyers may see inconsistent totals across the store. Always set Display Prices, Subtotals, and Shipping Amounts in cart and invoices. Turn on Full Tax Summary for transparency. Clarity at every step builds customer trust.
No Testing Before Launch	Skipping Magento checkout testing causes last-minute issues. Merchants must simulate real orders across provinces. Testing catches tax errors and display gaps. Use different products, addresses, and discount types. Fix all issues before going live to avoid tax compliance risks.
