GST vs. PST in BC: Which Applies to Your Business?
GST and PST are separate tax systems administered by different governments. GST is the federal Goods and Services Tax administered by the Canada Revenue Agency. PST is British Columbia's provincial sales tax administered by the BC Ministry of Finance.
The tax that applies depends on the type of supply, where the customer receives it, the business's registration status, and other specific rules. GST generally applies to taxable supplies made in Canada, while BC PST applies to specified taxable goods, software, services, and other transactions under provincial legislation.

GST Small-Supplier Rules and BC PST Small-Seller Rules
GST and BC PST do not use one shared registration threshold. Each system has its own test, and the timing of registration can change depending on how the applicable limit is exceeded.
GST: the $30,000 small-supplier threshold
For most businesses, the GST/HST small-supplier threshold is based on taxable supplies, including zero-rated supplies. The CRA applies separate timing rules depending on whether the business exceeds $30,000 in a single calendar quarter or over the previous four consecutive calendar quarters.
- If you exceed $30,000 in one calendar quarter: you generally stop being a small supplier on the supply that causes you to exceed the threshold. Your GST/HST registration becomes effective no later than that day, and GST/HST must be charged on that threshold-crossing supply. CRA requires registration within 29 days of the effective date.
- If you exceed $30,000 over the previous four consecutive quarters, but not in one quarter: you generally remain a small supplier until the end of the month following the quarter in which the cumulative threshold is exceeded. Registration becomes effective no later than the first taxable supply after you stop being a small supplier, and CRA requires registration within 29 days of that effective date.
- If you remain below the applicable threshold: mandatory registration may not yet apply, although eligible businesses may choose voluntary registration.
PST: $10,000 is not a universal registration threshold
BC's $10,000 small-seller rule is an exemption with several conditions. A business should not assume it is exempt from PST registration merely because its BC sales are below $10,000.
Under BC Bulletin PST 003, a seller must satisfy all applicable small-seller conditions. These include requirements concerning where and how the business operates, the type of goods, software or services sold, revenue during the previous and upcoming 12-month periods, wholesale activity, and excluded product or accommodation categories.
- The seller must meet the BC location and business-premises conditions described in Bulletin PST 003.
- Retail sales must involve goods, software or services that qualify under the small-seller rules.
- Gross revenue from eligible retail sales must generally be $10,000 or less during the previous 12 months.
- Estimated gross revenue from eligible retail sales must generally be $10,000 or less during the next 12 months.
- The seller must satisfy the bulletin's restrictions regarding wholesale sales and excluded categories.
Filing Frequency: Confirm the Schedule Assigned to Your Account
GST/HST and PST filing schedules are not interchangeable. Your reporting frequency depends on the applicable tax program, registration details, revenue and other account-specific rules.
GST/HST registrants may have annual, quarterly or monthly reporting periods. BC PST registrants should confirm the reporting period assigned to their provincial account through current BC Ministry of Finance guidance or eTaxBC.
Do not assume the filing frequency used for one tax account also applies to the other.
You can also use our Small Business Tax Checklist in Canada as an internal planning checklist, while confirming actual due dates from the relevant government account.
Calculating GST and PST Correctly on Invoices
Tax treatment depends on what is being sold, where the supply is made, and whether the transaction is taxable, zero-rated, exempt, or subject to another provincial tax rule.
A BC sale of taxable goods can involve both GST and PST, but businesses should not apply a combined rate mechanically to every invoice. Services, software, cross-border transactions, exempt items and supplies delivered outside British Columbia can follow different rules.
For sales outside BC, review the federal place-of-supply rules and the tax rules of the destination province rather than relying on one fixed HST rate for all provinces.
Keep registration numbers and invoice information required for the relevant tax account and transaction type.
Input Tax Credits: Recovering Eligible GST/HST
A GST/HST registrant may be able to claim input tax credits for eligible GST/HST paid or payable on business purchases and expenses used in commercial activities, subject to the applicable CRA requirements and documentation rules.
This does not mean every amount of GST/HST paid by a business is automatically recoverable. Eligibility can depend on the type of expense, business use, supporting documentation and other tax rules.
BC PST operates differently and does not use the same general input-tax-credit system. PST exemptions can apply to certain purchases, including qualifying goods acquired for resale, when the applicable requirements and documentation are met.

Exempt and Zero-Rated Supplies Need Separate Treatment
A zero-rated GST/HST supply is taxable at 0%, while an exempt supply is treated differently. The distinction matters because input tax credit eligibility can differ.
BC PST also has its own exemptions. Do not assume that a GST/HST exemption or zero-rating automatically creates the same PST treatment.
When a product or service has special tax treatment, confirm the applicable federal and provincial rules for that specific transaction.
GST and PST Filing Deadlines and Late-Filing Consequences
Filing and payment dates can differ by tax account and reporting period. Penalties and interest can also change depending on the circumstances, amount owing, filing history and current government rules.
| Tax Account | What to Confirm | Where to Verify |
|---|---|---|
| GST/HST | Reporting period, return due date, payment date, balance owing and any applicable interest or penalties. | CRA My Business Account or current CRA guidance. |
| BC PST | Assigned reporting period, return due date, remittance date and any applicable provincial interest or penalties. | eTaxBC or current BC Ministry of Finance guidance. |
Avoid relying on an old article or a fixed penalty percentage when determining a current filing obligation. Confirm the rule that applies to the actual reporting period.
Tools and Systems That Support Sales-Tax Recordkeeping
Reliable GST and PST returns are easier to prepare when sales tax is coded and reconciled throughout the reporting period rather than reconstructed immediately before filing.
Accounting platforms such as QuickBooks Online and Xero can assist with transaction coding, receipt capture and tax-account reporting when they are configured correctly.
Software does not remove the need to review tax codes, exemptions, destination rules or unusual transactions. The quality of the filing still depends on the underlying records and configuration.
Frequently Asked Questions
Is GST registration required the exact day my total sales pass $30,000?
It depends on how the threshold is exceeded. If taxable supplies exceed $30,000 in a single calendar quarter, the supply that causes the business to exceed the threshold is generally part of the effective-date calculation. If the threshold is exceeded over the previous four consecutive quarters but not in one quarter, the effective date occurs later under CRA's cumulative-quarter rule.
Do I have 30 days to register for GST/HST after exceeding the threshold?
CRA guidance states that registration is required within 29 days of the applicable effective registration date. The effective date itself depends on which small-supplier threshold test was exceeded.
Is every BC business under $10,000 exempt from PST registration?
No. The $10,000 figure is part of BC's small-seller rules, but a seller must meet all of the conditions in Bulletin PST 003. Revenue alone does not determine eligibility.
Can I prepare sales-tax filings from bank statements alone?
Bank statements can help reconcile cash activity, but they are often insufficient on their own because they may not show the tax treatment, invoice details, exempt amounts or documentation needed to support a filing.
What should I do if my GST or PST totals do not look right?
Review transaction tax codes, invoices, receipts, adjustments and reconciliations before submitting the return. If the difference cannot be explained, resolve the bookkeeping issue before relying on the calculated balance.
