GST/HST, PST and USD pricing on payroll software: what Canadian employers actually pay

A payroll or HR software subscription, and a full-service payroll provider's fees, are generally taxable supplies in Canada: expect GST/HST on the invoice, QST if you are in Quebec, and in some provinces provincial sales tax on software. A GST/HST-registered employer can usually claim the GST/HST back as an input tax credit (ITC), so the real cost is the pre-tax price plus a cash-flow delay, but provincial sales tax is generally a final cost. If the plan is priced in US dollars, the Canadian-dollar cost also moves with the exchange rate and any card foreign-exchange fee. Budget both with the renewal, FX and tax-inclusive calculator.

This guide is part of the payroll and HR software comparison overview. Tax rates below were checked against CRA pages in October 2026; they change, so confirm on canada.ca before relying on them.

Sales tax rates that commonly apply

The place-of-supply rules for services and intangible property decide which rate applies, generally based on the customer's address. If you have locations in several provinces, ask the vendor which address it uses.

Foreign vendors and the digital economy rules

Since 1 July 2021, non-resident vendors of digital services that sell to Canadian consumers must register under a simplified GST/HST regime and charge GST/HST. For businesses, the key points are:

• Simplified registrants are not supposed to charge GST/HST to a GST/HST-registered business that gives them its registration number, and tax charged by a simplified registrant generally cannot be claimed as an ITC. Give the vendor your GST/HST number when you sign up.
• If a foreign vendor is not registered and charges no tax, a business using the software exclusively in commercial activities generally does not need to self-assess GST/HST on the imported service. Organisations with exempt activities (for example some financial services, health care or charities) should check the self-assessment rules.
• In Quebec, Revenu Québec has its own specified QST registration regime for suppliers outside Quebec.

To claim an ITC for GST/HST charged by a regular registrant, keep invoices showing the vendor's GST/HST number and the information the CRA requires (more details are needed for purchases of $100 or more and of $500 or more).

USD pricing and exchange-rate risk

Some payroll and HR tools, especially US-based HR suites and employer-of-record services, bill in US dollars. Three things change the Canadian-dollar cost:

1. The exchange rate on the day the charge is converted.
2. The card or bank conversion fee, often a percentage on top of the rate.
3. Renewal increases in the vendor's US-dollar list price.

Illustrative example. A 25-person plan costs US$180 a month. At an illustrative 1.38 CAD per USD and a 2.5% card FX fee, each month costs 180 × 1.38 × 1.025 = C$254.61. If the Canadian dollar weakens to 1.44, it becomes 180 × 1.44 × 1.025 = C$265.68, about 4.3% more with no change in the vendor's price. Over a year, that is roughly $3,055 versus $3,188.

Ways to reduce the risk:

• ask for CAD billing; many vendors that sell in Canada offer it;
• pay with a card or account that has no FX fee or a low one;
• choose annual billing in CAD if the vendor offers a fixed CAD price;
• add an FX buffer to your budget, as in the calculator.

For official reference rates, the Bank of Canada publishes daily indicative exchange rates.

Renewal uplift: the second moving part

Renewal increases are usually stated as a percentage of the current price. Combined with an FX buffer, they give the amount to budget:

Illustrative example (the calculator's defaults): current yearly cost $3,000; announced increase 8%; FX buffer 4%; a new add-on costing $240.

• Extra to budget: $3,000 × 12% + $240 = $600
• Budget for next year: $3,600 before tax
• With 13% HST in Ontario: $3,600 + $468 = $4,068 cash cost, of which $468 is normally recoverable as an ITC

Negotiating a renewal cap is covered in contract renewal and exit terms, and pricing structures in pricing models.

Accounting for the subscription

Payroll software fees are normally an operating expense for income tax purposes. Whatever the treatment, record the tax correctly: GST/HST you can recover goes to the ITC account, while non-recoverable PST is part of the expense. If your accounting software and payroll software are linked, make sure the vendor invoice is not double-counted as payroll expense; see integrations with accounting, time and benefits.

FAQ

Is a full-service payroll provider's fee taxable?

Generally yes. Payroll processing services are taxable services in Canada, so GST/HST (and QST in Quebec) applies to the provider's fees. The wages themselves and the source deductions you remit are not part of that taxable fee.

Why did a US vendor charge me GST/HST?

Because it is probably registered under the simplified regime and treated you as a consumer. Give it your GST/HST registration number and ask it to stop charging tax, since tax charged by a simplified registrant is generally not recoverable as an ITC.

Do I pay BC PST on a payroll subscription?

PST can apply to software, including software provided as a service, purchased for use in BC. Check the BC government's PST bulletins on software for the current rules and exemptions.

Does the exchange rate affect what I remit to the CRA?

No. Payroll remittances are in Canadian dollars and are not affected. Only the vendor's subscription price moves with the exchange rate.
