Understanding Proportional Taxation on Shipping
With the Canadian tax holiday, Shopify has implemented a system to simplify tax collection for merchants. This includes automatic zero-rating of properly categorized products and proportional calculation of shipping tax for orders with zero-rated items. This change applies to GST and requires merchants to use registration-based taxes.
What Are Zero-rated Items?
Zero-rated items are products exempt from taxes under specific legislation, such as the Canadian tax holiday. Shopify automatically adjusts these categories based on their eligibility, reducing administrative burdens for merchants.
Changes to Shipping Tax Calculations
Previously, shipping tax was calculated solely on the rate of the taxable items in the order. Now, shipping taxes are proportionally calculated using a blended rate:
- Tax rates are weighted by the line-item quantity and individual tax rates in the order.
- Zero-rated or tax-exempt items affect the overall shipping tax rate.
- This approach ensures fair application of tax laws for mixed-product orders.
Example of Proportional Taxation
Imagine an order comprises two items:
- Product A: $10, taxed at 20%
- Product B: $30, zero-rated (0% VAT)
- Shipping: $10
Under the new proportional calculation:
- Product A rate: $10 x (1/2) x 20% = $1 tax
- Product B rate: $10 x (1/2) x 0% = $0 tax
- Total shipping tax: $1 + $0 = $1 tax
Key Dates and Details
Starting December 17, 2024, Shopify will automatically apply proportional tax calculations to shipping when zero-rated and taxable products are included in an order. Note that this change does not apply to manually-set tax rates, such as Legacy Tax or overrides.
Steps to Prepare for This Change
Here’s what you need to do:
- Review your product categories to ensure they are accurate.
- Disable manual tax overrides for affected categories.
- Ensure your store uses registration-based taxes.
Using the bulk editor in Shopify can help streamline category updates across multiple products.
