What is Provincial Sales Tax (PST) for SaaS?

Provincial Sales Tax (PST) is a consumption tax some Canadian provinces levy on SaaS (i.e., subscriptions to web-based applications delivered by the vendor via the internet). This is subject to provincial law: a province determines if it is taxable as software, computing in general, or related computer services under its own law.

In certain Canadian provinces, SaaS is subject to PST; however, this is not the practice across all provinces. PST being a provincial tax, it is separate from the federal GST/HST. This outcome suggests that SaaS might involve both taxes in parallel.

The provinces where PST on SaaS is primarily levied are British Columbia, Saskatchewan, and Manitoba, each of which has explicitly integrated SaaS into its tax system. Provinces do not define “SaaS” by its marketing label, but by its functional characteristics and access method. Charges for the rights or use of cloud-based software delivered electronically are generally taxable.

For transactions with persons outside a province (i.e: foreign countries, interprovincial sales), PST is determined by the place where the customer uses or receives the service (consummation), not where the seller is based. Sellers need to verify the consumer’s taxing jurisdiction by such location documents as:

•     Billing addresses.
•     The actual location of devices.
•     Number of users per location (multi-jurisdiction accounts).

Different provinces will have different approaches:

• In the Prairie province of Saskatchewan, the PST will be collected whenever your services are sold for consumption in the province.
•     BC mainly concentrates on whether the software was “acquired for use on a device normally located in BC”.
•     Manitoba taxes cloud services where the purchaser or device is ordinarily situated in Manitoba, and allows proration based on the share of Manitoba users or licences.

Businesses selling taxable SaaS in PST provinces must register, collect, file, and remit under each of the applicable province’s laws. For instance, Saskatchewan requires PST collection of taxable computer services from non-resident and resident providers, whereas Manitoba legislation imposes similar requirements. The requirements are the same: if you are selling taxable computer services online to customers in these three provinces, you must register, collect, file, and remit under the respective province’s rules.

A practical compliance checklist:

• Determine your nexus in each province.
• Identify all taxable provinces where you have customers.
• Register where required.
• Configure your tax engine to apply the right rates.
• Retain evidence of customer location.

Exemptions are not extensive and generally have specific boundaries, with their characteristics differing. Developing identical rules for every situation presents practical considerations.

• For example, Saskatchewan permits proration and provides some exclusions for electronically delivered software consumed outside the provincial boundaries.
• Manitoba, meanwhile, has a few exceptions to the general rule when specific custom modifications have been made on software that is already taxable.

Reviewing each province’s legislation is advisable, as developments such as BC’s cloud-based software exemption can lead to varying outcomes.

PST is applied only to the portion of the selling price after subtracting discounts (provided that the discounts are valid and are applied at the point of sale). Any credits, refusals, or even partial settlements can only be considered if they are linked to the original amount received and, preferably, have formal documentation.

Example: A $100 SaaS subscription with a $10 promotional discount is taxed on the discounted $90.

To stay compliant:

• Separate taxable and non-taxable components on invoices.
• Document all promotional discounts.
• Track credits and refunds to prevent over- or under-collection.
