Saskatchewan PST Calculator 2026 — GST + PST

Understanding Saskatchewan PST

Saskatchewan uses a dual tax system with federal GST and provincial PST applied separately to most goods and services.

Saskatchewan PST Exemptions and Rules

Saskatchewan PST is a retail sales tax administered by the Saskatchewan Ministry of Finance. Unlike GST, which is a federal value-added tax with input tax credits, Saskatchewan PST is a single-stage tax applied at the point of sale to the final consumer. Businesses cannot claim PST back as an input tax credit, which makes it a real cost for any purchases you do not resell.

Common PST Exemptions in Saskatchewan

Not everything sold in Saskatchewan is subject to PST. The following categories are exempt from the 6% provincial sales tax:

• Basic groceries -- Unprepared food items including fresh produce, meat, dairy, bread, and cereal are exempt from PST (and from GST). Prepared foods, snacks, and restaurant meals are taxable.
• Prescription drugs -- Medications prescribed by a licensed practitioner are PST-exempt. Over-the-counter drugs and vitamins are taxable.
• Children's clothing and footwear -- Clothing and footwear sized for children up to and including size 16 (girls) and size 20 (boys) are exempt. Adult-sized clothing is taxable regardless of who wears it.
• Farm machinery and equipment -- Qualifying farm machinery used directly in farming operations is exempt. This includes tractors, combines, seeders, and qualifying parts. The exemption does not extend to vehicles licensed for highway use.
• Residential utilities -- Electricity and natural gas for residential heating are PST-exempt. Commercial and industrial utility usage is taxable.
• Books and reading materials -- Printed books, newspapers, and magazines are exempt from Saskatchewan PST.
• Medical devices -- Wheelchairs, hearing aids, prosthetics, and other prescribed medical devices are exempt.

PST on Services vs. Goods

Saskatchewan PST applies to both tangible goods and certain services. This is a distinction that catches many businesses off guard, because some provinces only tax goods. In Saskatchewan, taxable services include:

• Repair and installation services -- Repairing, cleaning, or installing tangible personal property is taxable. This includes auto repair, computer repair, and appliance servicing.
• Telecommunications services -- Phone service, internet access, and cable television are subject to PST.
• Accommodation -- Hotels, motels, and short-term rental accommodation are taxable.
• Insurance premiums -- Most insurance premiums are subject to a separate Insurance Premiums Tax, but certain services related to insurance may also attract PST.
• Commercial vehicle rentals -- Renting or leasing vehicles and equipment is taxable.

Professional services such as accounting, legal advice, and consulting are generally not subject to Saskatchewan PST. Construction labour for real property (buildings) is also generally exempt, though materials used are taxable.

Saskatchewan PST Vendor Registration

Unlike federal GST, which has a $30,000 small supplier exemption, Saskatchewan PST has no minimum revenue threshold for registration. If you sell or lease taxable goods or services in Saskatchewan, you must register as a PST vendor with the Saskatchewan Ministry of Finance before making your first taxable sale. This applies to both Saskatchewan-based businesses and out-of-province businesses that sell into Saskatchewan.

To register, complete Form PST-1 (Application for Provincial Sales Tax Vendor's Licence) and submit it to the Ministry of Finance. There is no fee for registration. Once registered, you receive a PST vendor number that must appear on all invoices involving taxable sales.

PST Filing Frequency Rules

Your PST filing frequency depends on the amount of tax you collect annually:

• Monthly filing -- If you collect more than $12,000 in PST per year, you must file monthly returns. Returns are due on the 20th of the month following the reporting period.
• Quarterly filing -- If you collect between $4,800 and $12,000 in PST per year, you may file quarterly. Returns are due on the 20th of the month following the end of each quarter.
• Annual filing -- If you collect less than $4,800 in PST per year, you may request annual filing. The return is due April 20th for the previous calendar year.

Late filing attracts a penalty of 10% of the tax owing plus interest at the prescribed rate. The Ministry of Finance may also suspend your vendor's licence for persistent non-compliance.

Common Mistakes with Saskatchewan PST Calculations

Business owners frequently make these errors when calculating and remitting Saskatchewan PST:

• Applying PST on top of GST -- In Saskatchewan, PST is calculated on the selling price only, not on the GST-included amount. PST and GST are calculated independently on the same base amount. This is different from the old Quebec QST rule (pre-2013) where QST was calculated on the GST-included amount.
• Forgetting PST on taxable services -- Many businesses correctly charge PST on goods but forget to charge it on taxable services like repairs, telecommunications, and equipment rentals.
• Not charging PST on out-of-province sales into SK -- If you ship taxable goods to a Saskatchewan address, PST applies regardless of where your business is located. This is a common compliance gap for e-commerce sellers.
• Claiming PST as an ITC -- Unlike GST/HST, Saskatchewan PST cannot be recovered through input tax credits. PST paid on business purchases is an expense on your income statement, typically recorded in the relevant expense category or as a separate PST expense line.
• Incorrect exemption claims -- Selling goods PST-exempt without proper documentation (such as a valid exemption certificate from the buyer) can result in the vendor being held liable for the uncollected tax plus penalties.
