Do Tax Experts in Regina Handle GST/HST Returns?
Yes, and here is what they actually do, how Saskatchewan's separate GST and PST work, how often you file, where returns go wrong and how to choose the right help.
1. The Short Answer
Yes. Accountants and tax professionals in Regina handle GST returns every day. They register new businesses, set up the accounting system so tax is tracked correctly, prepare and file returns with the Canada Revenue Agency (CRA), claim input tax credits, and represent clients if the CRA asks questions. Many also look after Saskatchewan's separate provincial sales tax.
The phrase "GST/HST" is how the federal tax is described across Canada, but in Saskatchewan the harmonized part does not apply. Saskatchewan has no HST. Instead, businesses collect 5% federal GST and, where it applies, 6% Saskatchewan PST. They are two different taxes, administered by two different governments, with two sets of rules and returns.
This matters because mixing them up is a common source of errors. Our core accounting and tax services are built around keeping them separate, so your books tell you what you collected, what you owe and what you can claim back.

2. Who Handles GST Returns
| Professional | Typically helps with | Good fit when |
|---|---|---|
| CPA or accounting firm | Registration, returns, ITC review, planning, CRA representation, financial statements | You want advice as well as filing |
| Bookkeeper | Recording sales and purchases, tax codes, return preparation in some cases | Your needs are mostly day-to-day record keeping |
| Tax preparation service | Return preparation, often seasonal | Your situation is simple and your records are clean |
| Payroll provider | Payroll remittances (not GST) | You need payroll only; GST is separate |
| Tax lawyer | Disputes, objections, complex structures | You face a significant assessment or dispute |
To let a professional deal with the CRA for you, you normally need to authorize them through the CRA's process, and you should keep that authorization current. Confirm what is included in the service before you sign: preparation and filing, review of your books, or full representation.
3. Saskatchewan Sales Tax at a Glance
| Feature | GST (federal) | PST (Saskatchewan) |
|---|---|---|
| Rate | 5% | 6% |
| Administered by | Canada Revenue Agency | Saskatchewan Ministry of Finance |
| Registration trigger | Taxable revenue over $30,000 (small supplier rule), or voluntary | Making taxable retail sales in Saskatchewan; no dollar threshold in published guidance |
| Recoverable on business purchases? | Generally yes, as input tax credits | No, PST paid is generally a cost |
| Filing | CRA schedule: annual, quarterly or monthly | Provincial schedule; electronic filing through the province's online system |
| Appeals | Notice of objection, then Tax Court of Canada | Provincial process |
Because published sources differ in detail on some provincial points, confirm current PST rules, registration and filing steps with the Saskatchewan Ministry of Finance or your tax professional.
4. What a Tax Expert Does on Your GST Return
- Registration: determines whether you must register and when, and sets up your account.
- Tax set-up: configures tax codes in your accounting software so GST collected and paid are tracked automatically.
- Reconciliation: ties sales and purchases to the ledger and checks that GST collected and paid agree with your records.
- Return preparation and filing: completes the return, calculates the net amount and files and pays by the deadline.
- Input tax credits: checks that claims are supported and eligible, and flags purchases that are not.
- Special treatment: advises on exempt, zero-rated and mixed supplies, and on elections available to your business.
- Reviews and audits: responds to CRA requests, organizes support and negotiates where needed.
- Corrections: fixes errors and, where appropriate, considers a voluntary disclosure.
The books behind the return matter most. Our guide on double-entry bookkeeping for SMEs explains how GST receivable and payable accounts should be set up, and bookkeeping experts describe common small business mistakes that undermine sales tax reporting.
5. Registration and Filing Frequency
GST filing frequency generally depends on annual taxable supplies. The thresholds below come from published guidance and should be confirmed with the CRA for your situation.
| Annual taxable supplies | Filing frequency | Due |
|---|---|---|
| $1,500,000 or less | Annual | Three months after fiscal year-end (instalments one month after each quarter may apply) |
| More than $1,500,000 up to $6,000,000 | Quarterly | One month after the end of each quarter |
| More than $6,000,000 | Monthly | One month after the end of each month |
Illustrative Quarterly GST Return Workflow
Illustrative schedule for a quarterly filer whose return is due one month after quarter-end. Aim to finish early so a missing receipt does not become a late return.
If a due date falls on a weekend or a public holiday, published guidance says payment is on time if received by the next business day. Weekend and holiday rules can change, so confirm the date on your own account.
6. A Worked GST Return Example
The figures below are hypothetical and use the 5% GST rate. They show how a return nets out.
| Line (hypothetical quarter) | Amount |
|---|---|
| Taxable sales for the quarter | $50,000 |
| GST collected (5%) | $2,500 |
| Eligible purchases with GST | $24,000 |
| GST paid on those purchases (input tax credits) | $1,200 |
| Net GST to remit ($2,500 − $1,200) | $1,300 |
Hypothetical GST Collected vs. Claimed
Hypothetical example. If input tax credits exceed GST collected, the return shows a refund instead.
7. Input Tax Credits and Documentation
Input tax credits reduce what you remit, so the CRA looks at them closely. Published tax commentary highlights these documentation points:
- Invoice in the right name: if a related company pays on your behalf, ask for a separate invoice in your business's name, and have misspelled names corrected.
- Supplier must be a registrant: a credit is invalid if the seller is not registered for GST, so check suppliers where it matters.
- Supplier registration numbers: larger invoices generally must show the supplier's registration number; keep the invoice and a record of your check.
- Business use: credits are for purchases used in commercial activity; personal items and some categories are restricted.
- Keep records: retain support for the standard period; see our guide on transitioning to compilation from review for how organized records help when lenders ask for statements.
8. PST for Regina Businesses
Saskatchewan PST is where a Regina business can differ from one in Ontario or Nova Scotia. A few points from published guidance, to be confirmed with the province:
- Who registers: businesses making taxable retail sales into Saskatchewan, including out-of-province and online sellers, generally need to register; published guidance cites no dollar threshold.
- What is taxable: many goods and services, and software and many digital services are generally PST-taxable in addition to GST.
- Exemptions: basic groceries and prescription drugs are zero-rated for GST and exempt from PST, and reading materials are PST-exempt.
- Buying for resale: a business can generally buy goods for resale without paying PST by giving its vendor licence number to the supplier.
- Filing: PST returns are filed electronically with the province, with reporting frequency tied to the amount of PST reported. One published source describes annual filing under $4,800 of PST a year, quarterly between $4,800 and $12,000 and monthly above $12,000, with electronic returns due by the last day of the following month. Verify your own schedule before relying on it.
Because PST paid on business purchases is generally not recoverable, a tax expert will review where you buy and what you pay it on, which can affect pricing and margins.

9. Common Mistakes
| Mistake | Why it happens | How to avoid it |
|---|---|---|
| Treating Saskatchewan like an HST province | Assuming one combined tax | Track GST and PST separately; file each with the right agency |
| Claiming credits without proper invoices | Receipts lost or wrong name | Attach invoices to transactions; verify supplier details |
| Claiming PST as an input tax credit | Confusing recoverable GST with PST | Separate accounts; train staff |
| Wrong tax codes in software | Defaults not reviewed | Review codes with your accountant; test with sample entries |
| Mixing personal and business purchases | One card used for both | Separate accounts; owner accounts in the ledger |
| Missing the registration threshold | Sales grow past $30,000 unnoticed | Monitor rolling four-quarter revenue |
| Returns not tied to the books | Filing from memory or a spreadsheet | Reconcile GST accounts before each filing |
10. Late Returns, Errors and Reviews
Late or incorrect returns can bring penalties and interest from the CRA, and late PST can bring a provincial penalty plus interest. Published commentary from tax professionals offers several cautions:
- Paperwork errors count: penalties can be aimed at documentation mistakes, not only unpaid tax.
- False claims are serious: commentary notes potential penalties of up to 200% on a false refund claim, with lower penalties in some no-negligence situations. Confirm current rules.
- Voluntary disclosure: correcting an error before the CRA contacts you can, in some cases, bring substantial penalty and interest relief; conditions apply.
- Reviews can look back: commentary notes the CRA may review returns years later, so keep support.
- Interest and penalties are generally not deductible for income tax purposes.
If you have missed returns or suspect past errors, speak to a professional early. Our specialized services cover more complex situations, including multi-year cleanups.
11. Special Situations
- Construction and development: GST treatment can differ between residential and commercial projects, and costs can swing with overruns; see residential vs. commercial construction feasibility and cost overruns in Canadian construction.
- Mixed exempt and taxable revenue: some businesses, such as certain health practices and financial services, have exempt and taxable activity and must allocate input tax credits carefully.
- Online and cross-border sales: rules for selling into Saskatchewan or buying from outside Canada have their own requirements.
- Lender reporting: if a lender wants compiled statements, understand the process in our guide to the compilation engagement process; clean GST accounts make it faster.
- Growth and forecasting: for planning, our CFO advisory services and business planning and financial modeling include tax cash flow in forecasts.
12. How to Choose a Tax Expert in Regina
| Question to ask | What a good answer sounds like |
|---|---|
| Do you handle both GST and Saskatchewan PST? | Yes, or a clear explanation of who does what |
| What is included in the fee? | A written scope: preparation, filing, reconciliation, CRA correspondence |
| How will you get my records? | Software access or a defined handover process |
| What happens if the CRA contacts me? | They explain representation and authorization |
| How do you handle deadlines? | A calendar and early-warning process |
| Do you advise on structure and planning? | They can connect GST to wider tax and cash planning |
13. Risk Management: Financial Risk and Business Risk
Sales tax is a quiet source of risk. Financial risk is the cost of errors: unpaid tax, denied credits, penalties and interest. Business risk is the disruption: a review that consumes management time, a lender questioning your records or a cash squeeze when a large remittance is due.
| Risk | Type | Control |
|---|---|---|
| Denied input tax credits | Financial risk | Invoice checks; documentation attached to transactions |
| Penalties and interest on late filing | Financial risk | Filing calendar; early reconciliation; payment buffer |
| PST and GST mixed up | Financial risk | Separate accounts and codes; periodic review |
| Cash shortfall at remittance time | Financial risk | Set aside collected tax; include in cash flow forecast |
| Review or audit disrupts operations | Business risk | Organized records; designated contact; professional representation |
| Reliance on one person who knows the process | Business risk | Written procedure; backup person |
| Lender concerns about unreliable records | Business risk | Monthly close; professional statements when needed |
| Missed registration threshold | Business risk | Rolling revenue monitoring |
14. GST Readiness Checklist
- GST and PST status confirmed for each revenue stream.
- Tax codes in your accounting software reviewed by an accountant.
- Separate accounts for GST collected, GST paid and PST.
- Filing frequency and due dates for GST and PST on a shared calendar.
- Invoices and receipts attached to transactions, with supplier details checked.
- GST accounts reconciled to the ledger before each return.
- CRA authorization in place for your accountant, if desired.
- Funds for the remittance set aside each month.
- Six years of records retained and backed up.
15. Frequently Asked Questions
Do accountants and tax experts in Regina file GST/HST returns?
Yes. Accounting firms and tax professionals in Regina commonly register businesses for GST, set up tax codes, reconcile sales tax accounts, prepare and file GST returns with the CRA, claim input tax credits and help with reviews or audits. Many also help with Saskatchewan PST returns. You normally need to authorize them with the CRA before they can deal with it on your behalf.
Does Saskatchewan charge HST?
No. Businesses charge the 5% federal GST, administered by the CRA, and separately charge the 6% Saskatchewan PST, administered by the Saskatchewan Ministry of Finance. That means two registrations and two returns, and only the GST paid on business purchases is generally recoverable through input tax credits.
When do I have to register for GST in Saskatchewan?
Generally once your taxable revenue exceeds $30,000 over four consecutive calendar quarters, although some businesses register earlier to claim input tax credits. PST registration is separate and applies to businesses making taxable retail sales in Saskatchewan, with no dollar threshold in published guidance. Confirm your situation with a tax professional.
How often do I file GST and PST returns?
GST filing generally depends on annual taxable supplies: annual for $1.5 million or less, quarterly between $1.5 million and $6 million, and monthly above $6 million. Published guidance describes PST reporting as annual, quarterly or monthly depending on the amount of PST reported. Due dates differ, so confirm your schedule with the CRA and the Saskatchewan Ministry of Finance.
What should I do if I filed a GST return incorrectly or late?
Speak to a tax professional promptly. Correcting errors and filing missing returns before the CRA contacts you may allow a voluntary disclosure, which published commentary says can bring significant penalty and interest relief in some cases. Penalties and interest can apply to late or incorrect returns, so acting early generally limits the damage.
16. Final Thoughts
Tax experts in Regina do handle GST returns, and the best ones do much more: they keep GST and PST separate, build tax into your books, check your credits before you claim them and plan the cash for each remittance. Treat sales tax as part of your risk management, not a form you complete at the deadline, and the financial risk of penalties and the business risk of a disruptive review both shrink.
