Saskatchewan — Provincial Sales Tax (PST) — Skill v1.0

1. Quick reference

Item	Value
Standard PST rate	6%
Liquor consumption tax	10%
Tobacco tax	Specific per-unit rates (not ad valorem)
Passenger vehicle PST	6% (with valuation rules for used vehicles)
Registration threshold	None — any business making taxable retail sales in SK must register
Federal GST also applies	Yes — 5% GST + 6% PST = effective 11% on most taxable supplies
Administering body	Saskatchewan Ministry of Finance, Revenue Division
Filing portal	SETS — Saskatchewan eTax Services
Legal basis	The Provincial Sales Tax Act (Saskatchewan), and regulations thereunder

Saskatchewan is a non-harmonized PST jurisdiction (alongside BC and Manitoba). It is not part of the HST system. PST stacks on top of GST and is calculated on the GST-exclusive price of the supply.

2. Required inputs + refusal catalogue

Required inputs

Before preparing or advising on a SK PST return / position, collect:

1. Vendor permit number (PST account number issued by SK Ministry of Finance).
2. Filing frequency (monthly / quarterly / annually) as assigned at registration.
3. Reporting period (start and end dates).
4. Gross sales for the period, broken down by:
   • Taxable tangible personal property (TPP) sold to SK customers
   • Taxable services rendered in SK (lawn care, telecom, accommodation, legal/accounting, computer services, etc.)
   • Insurance contracts subject to PST
   • Exempt sales (groceries, prescription drugs, children's clothing, agricultural inputs, residential rent)
   • Out-of-province sales (no SK PST — but watch for nexus into BC/MB/QC)
5. PST collected during the period.
6. PST self-assessed on taxable goods/services purchased without PST charged (e.g., out-of-province purchases for own use in SK).
7. Commission entitlement (vendors may retain a small collection commission — confirm current rate via SETS portal).
8. Bad debt write-offs for which PST was previously remitted.
9. Refunds / credits to customers during the period.

Refusal catalogue (route elsewhere)

This skill does not cover, and you must refuse / redirect:

• R-SK-1 — Quebec QST or any other provincial sales tax (route to qc-qst, bc-pst, mb-rst).
• R-SK-2 — Federal GST/HST mechanics (route to canada-gst-hst).
• R-SK-3 — Liquor, tobacco, fuel, cannabis-specific commodity taxes (route to dedicated commodity-tax skills; this skill mentions liquor 10% only for rate awareness).
• R-SK-4 — Real-property transactions (PST does not apply to real property itself; PST applies to services to real property such as construction materials and certain contractor services — handle with care and route complex construction contract questions to a credentialed SK practitioner).
• R-SK-5 — Indigenous tax exemptions on reserve land — fact-specific, route to a credentialed practitioner.
• R-SK-6 — Insurance premium tax (a separate tax administered by Finance — not the PST on insurance contracts; do not conflate).
• R-SK-7 — Audit defence, voluntary disclosure, ruling requests — these require credentialed reviewer signoff.
• R-SK-8 — Pre-2017 reporting periods — rules expanded materially in 2017 and again 2018–2022; this skill is scoped to current law for 2025.

3. Rate

Category	Rate	Notes
Standard PST	6%	Applies to taxable TPP, listed services, and insurance contracts
Liquor consumption tax	10%	Replaced the previous 10% Liquor Consumption Tax structure; applied in lieu of standard PST on beverage alcohol
Tobacco tax	Specific (per cigarette / per gram)	Not ad valorem; refer to current Ministry rate schedule
Passenger vehicles	6%	Used vehicles have valuation rules (greater of purchase price or Red Book / Black Book value, subject to thresholds)

PST applies on the GST-exclusive consideration. Effective combined burden on a typical taxable supply: 5% GST + 6% PST = 11%.

4. Registration

Who must register

A person must hold a Vendor's Licence (PST registration) if they:

• Regularly make retail sales of taxable goods or services in Saskatchewan, OR
• Are an out-of-province seller meeting the economic nexus tests (see §6), OR
• Operate as a contractor consuming taxable goods in SK, OR
• Provide taxable services in SK (lawn care, computer services, accommodation, legal, accounting, etc.).

There is no de minimis revenue threshold. Unlike the federal GST $30,000 small-supplier threshold, SK PST registration is required from the first dollar of taxable sales in SK.

How to register

Register via the SETS portal (Saskatchewan eTax Services) at sets.saskatchewan.ca. A vendor permit number is issued; this must appear on invoices where PST is charged.

Casual / one-off sellers

A taxpayer who makes only a single isolated sale (e.g., private sale of a used personal item) generally is not required to register. The buyer may, however, owe PST self-assessed on the purchase (e.g., used-vehicle PST collected at registration with SGI).

5. Taxable supplies

Saskatchewan's PST base is broader than BC's or Manitoba's following the 2017 and 2018–2022 expansions.

Taxable

• Tangible personal property sold for consumption in SK (default rule — all TPP is taxable unless specifically exempt).
• Listed taxable services, including (non-exhaustive):
  • Lawn care, snow removal, landscaping
  • Telecommunication services (including streaming and digital subscriptions — expanded 2022)
  • Accommodation (hotels, short-term rentals)
  • Legal services
  • Accounting and bookkeeping services
  • Computer services and software (including SaaS — expanded 2017)
  • Engineering, architectural, and surveying services
  • Repair and installation services to TPP and to certain real property
  • Veterinary services for non-livestock animals
  • Dry cleaning and laundry
  • Credit reporting and collection services
• Insurance contracts (most general insurance — life and health insurance are excluded; agricultural insurance and certain specified contracts have exemptions).
• Admissions to places of amusement (where applicable).

Self-assessment

Where a SK resident or business purchases taxable goods or services from an out-of-province vendor that did not charge SK PST, the purchaser must self-assess and remit PST on its next return.

6. Online platforms / out-of-province sellers

Saskatchewan has had economic nexus rules since 2018, expanded materially in 2020.

Who is caught

• Electronic distribution platforms (marketplaces) facilitating sales to SK customers.
• Online accommodation platforms (e.g., short-term rental marketplaces).
• Out-of-province sellers of TPP or taxable services to SK customers where the seller makes retail sales for consumption in SK.

Threshold

Unlike some jurisdictions, SK has no dollar safe harbour — the test is whether the seller is causing taxable goods/services to enter SK for consumption. A pattern of regular sales triggers the duty to register and collect.

Practical implication

A non-Canadian or non-SK e-commerce seller shipping into SK should register for a SK Vendor's Licence as soon as it is clear sales into SK are regular. Marketplace facilitators are generally responsible for collecting PST on third-party seller transactions on their platform.

7. Exemptions

PST does not apply to:

• Basic groceries (aligned conceptually with the GST zero-rating list, but defined under SK law).
• Prescription drugs and many medical devices.
• Children's clothing and footwear (subject to size / specification rules).
• Agricultural inputs — most farm machinery, fertilizer, seed, feed for livestock, and qualifying farm-use goods.
• Used goods sold privately between individuals (not in the course of business) — but PST may be self-assessed at registration (e.g., used vehicles via SGI).
• Residential rent and most residential real property transactions.
• Books (printed books with an ISBN — subject to current rules).
• Direct agents consumed in manufacturing (incorporated into the final product).
• Goods purchased for resale by a registered vendor providing a valid PST number to the supplier.
• Goods shipped out of province by the seller to a non-SK destination.

Exemption certificates / declarations must generally be obtained and retained for vendors not charging PST on exempt sales.

8. Filing

Portal

SETS — Saskatchewan eTax Services (sets.saskatchewan.ca). All registered vendors must file electronically via SETS unless granted an exemption.

Frequency

Assigned by the Ministry based on annual PST collected:

Annual PST collected	Filing frequency
> $7,200 / year (approx.)	Monthly
$1,200 – $7,200 / year (approx.)	Quarterly
< $1,200 / year (approx.)	Annually

Confirm current thresholds on SETS — the Ministry adjusts these from time to time.

Due dates

Returns and payment are due by the 20th day of the month following the reporting period end.

Vendor commission

Vendors that file and pay on time may retain a small commission (a percentage of PST collected, capped per return). Verify the current commission rate and cap on the SETS portal as part of any return preparation.

Penalties

Late filing and late payment attract penalties and interest. Persistent non-compliance can result in licence revocation and director liability for unremitted PST.

9. Coordination with federal GST

Saskatchewan is non-harmonized: 5% federal GST and 6% provincial PST apply separately and are both calculated on the GST-exclusive sale price.

Worked rate example

Sale price (PST/GST exclusive): $100.00

• GST 5%: $5.00
• PST 6%: $6.00
• Total to customer: $111.00

Note: SK PST is not calculated on top of GST (no tax-on-tax). The two taxes are parallel, both applied to the base price.

Input tax credits / refunds

• GST: Registered businesses recover input GST via ITCs on the GST34 federal return.
• PST: There is no general input tax credit mechanism. PST is a true retail sales tax — businesses generally pay PST on their inputs as a final cost, except where a specific exemption applies (resale, direct agents in manufacturing, qualifying farm inputs, etc.).

This is a major contrast with GST/HST and is the single most common error among first-time SK PST advisors: do not assume PST paid on business inputs is recoverable. It generally is not.

10. Worked example — Regina e-commerce with SK + national customers

Facts. Prairie Threads Inc., a Regina-based online clothing retailer, in Q2 2025:

• Sells children's clothing $40,000 (national mix) — assume $5,000 to SK customers, $35,000 elsewhere in Canada.
• Sells adult clothing $60,000 — assume $10,000 to SK customers, $50,000 elsewhere in Canada.
• Sells SaaS subscriptions to an inventory-tracking app $20,000 — assume $3,000 to SK customers, $17,000 elsewhere (mostly AB).
• Purchases $2,000 of office supplies from an Alberta vendor with no PST charged.
• Purchases $4,000 of packaging materials from a SK wholesaler — packaging is consumed in the business (not resold separately).

SK PST analysis.

Item	Amount	Taxable in SK?	PST collected
Children's clothing to SK customers	$5,000	Exempt (children's clothing exemption)	$0
Children's clothing to non-SK customers	$35,000	Out of province — no SK PST	$0
Adult clothing to SK customers	$10,000	Taxable @ 6%	$600
Adult clothing to non-SK customers	$50,000	Out of province — no SK PST (check destination PST)	$0
SaaS to SK customers	$3,000	Taxable @ 6% (computer services / telecom services expansion)	$180
SaaS to non-SK customers	$17,000	Out of province — no SK PST	$0

Self-assessment. Alberta office supplies $2,000 purchased without PST and consumed in SK → self-assess $120 SK PST.

Inputs not recoverable. The $4,000 packaging materials purchased from the SK wholesaler — PST of $240 was charged at the till. No ITC mechanism — this is a final cost (unless the packaging is incorporated into and sold with the product, in which case the "direct agent" / packaging exemption may apply; check current Ministry guidance and obtain a resale declaration).

Q2 return summary (PST only).

Line	Amount
PST collected on sales	$780
PST self-assessed	$120
Total PST payable	$900
Less: vendor commission (if eligible)	(small amount per SETS schedule)
Net remittance	~$900

Federal GST. Separately, Prairie Threads files a GST34 reporting GST collected on adult clothing nationally (children's clothing is GST zero-rated), and claims ITCs on GST paid on inputs.

11. Conservative defaults

When the facts are unclear, default conservatively:

1. When in doubt, register. SK has no dollar threshold; any pattern of regular SK sales argues for registration. A late registration is more painful than an early one.
2. When in doubt, charge PST. The expanded services base (post-2017 / 2022) means software, telecom, accommodation, and many professional services are taxable. If you cannot find a clear exemption, default to taxable.
3. When in doubt, self-assess. Out-of-province purchases consumed in SK without PST charged → self-assess on the next return.
4. Do not assume an input credit. Unlike GST, PST paid on business inputs is generally a final cost. Only claim a resale or direct-agent exemption where you have documentation supporting it.
5. Get a fresh rate confirmation from SETS before filing — rates and thresholds (especially filing-frequency cutoffs and vendor commission) are adjusted periodically.
6. Route complex construction, real property, indigenous, and audit-defence issues to a credentialed SK practitioner (refusals R-SK-4, R-SK-5, R-SK-7).
7. Document exemption claims — retain customer declarations, PST resale numbers, and shipping documentation for at least the statutory record-retention period.

Verification status. verified_by: pending — this skill must be reviewed and signed off by a Saskatchewan-credentialed practitioner before being relied upon for a client engagement. Conservative defaults are applied throughout, but rates, thresholds, and the scope of taxable services are subject to legislative and administrative change; always reconcile against the current SETS portal and Ministry bulletins at the time of filing.
