SK PST

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

1. Quick reference

Quick reference table

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)

• R-SK-1 — Quebec QST or any other provincial sales tax (route to qc-qst, bc-pst, mb-rst). (R-SK-1)
• R-SK-2 — Federal GST/HST mechanics (route to canada-gst-hst). (R-SK-2)
• 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-3)
• 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-4)
• R-SK-5 — Indigenous tax exemptions on reserve land — fact-specific, route to a credentialed practitioner. (R-SK-5)
• R-SK-6 — Insurance premium tax (a separate tax administered by Finance — not the PST on insurance contracts; do not conflate). (R-SK-6)
• R-SK-7 — Audit defence, voluntary disclosure, ruling requests — these require credentialed reviewer signoff. (R-SK-7)
• 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. (R-SK-8)

3. Rate

Rate table

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 base and combined burden — 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

• 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.).
• Registration threshold — None CAD (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

• 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

• Casual 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

• Taxable items list — 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

• Self-assessment rule — 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

• 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

• Nexus threshold — None — no dollar safe harbour CAD (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

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

8. Filing

Portal

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

Frequency

Filing frequency table

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

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

Vendor commission

• 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

• 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

• Non-harmonized coordination — 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

• 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

• ITC comparison — 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

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 table

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

• Conservative defaults list — 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.
