# Month-end close: PST in Saskatchewan Saskatchewan's PST is 6%, a nil return is still required, and since October 2024 the 10% late-payment penalty has no $500 cap. This is part of the [sales tax checklist](/month-end-close-checklist/sales-tax). Saskatchewan charges its own PST on top of GST. It is filed with the Ministry of Finance, and the GST steps are on the [Canada page](/month-end-close-checklist/sales-tax/canada). **Rate.** 6% PST on taxable goods, services and insurance contracts used or consumed in Saskatchewan. GST is left out of the amount PST is calculated on. **Filing.** The tax reported sets it: annual up to $4,800 a year, quarterly $4,800 to $12,000, monthly over $12,000. A return with nothing to report is still filed, as a nil return. **Due.** The last day of the month after the period when the return is filed and paid electronically. Otherwise the 20th. **The trap.** A late payment costs 10% of the tax, with no $500 cap since October 1, 2024. A return not filed by its due date costs $50 for each period, and interest is the prime rate plus 3%. ## The month-end steps 1. **Check registration.** All businesses operating or making retail sales in Saskatchewan must be registered with a PST number. The exception is a small trader: an individual who produces goods at home and sells them on a small scale, with annual sales under $10,000, and who pays PST on the equipment and supplies used. A business outside Saskatchewan that makes retail sales in the province must also be licensed to collect PST [1]. Done when each client holds a PST number or qualifies as a small trader. 2. **Confirm what's taxable.** PST applies to taxable goods, certain services, and insurance contracts. Bulletin PST-46, Service Enterprises, covers the services. Basic groceries, reading materials, agricultural equipment and prescription drugs are among the exempt goods [1]. Done when each kind of sale the client makes has been checked. 3. **Check the rate.** The rate is 6%, with GST left out of the amount PST is calculated on [1]. Done when each taxable sale carries 6% of its pre-GST price. 4. **Check purchases without PST.** Tax on goods or services bought from a supplier that did not collect it, such as an unlicensed supplier outside Saskatchewan, is self-assessed and paid directly to the Ministry of Finance [1]. Done when the client's untaxed purchases for use in Saskatchewan have been listed. 5. **Find the filing frequency.** It follows the tax reported [2]: | # | Tax reported | Frequency | |---|---|---| | 1 | $0 to $4,800 a year | Annually | | 2 | $4,800 to $12,000 a year | Quarterly | | 3 | Over $12,000 a year | Monthly | If there is no tax to report for the period, a nil return is still required [2]. 6. **Work out the due dates.** A return filed and paid electronically is due the last day of the month after the period. A return filed or paid non-electronically is due on the 20th. If the date falls on a weekend or statutory holiday, payment and remittance are due the next business day [1] [2]. Done when each return's due date is on the client's calendar. 7. **Know what late costs.** Since October 1, 2024, failing to pay by the due date costs 10% of the tax for each return period, with no $500 maximum. Failing to file a return by the due date costs $50 for each return period. Failing to produce books, records or documents as required costs $500 each time, and failing to file in the manner required costs $100 each time. Interest is the prime rate plus 3%, set every six months [3]. Done when each return and payment went in by its due date, or the late ones are flagged for the client. 8. **Tie the liability.** Done when the PST payable account is at zero after the month's payment, or equals the tax not yet due. ## Sources 1.
