Do I Need to Register for GST in BC? A Small Business Guide
GST registration is an important step for a growing BC business. The $30,000 small supplier threshold is familiar, but the timing rules differ depending on whether you exceed it in one quarter or over four consecutive quarters.
This guide helps business owners in Vancouver, Surrey, the Lower Mainland, Fraser Valley, Vancouver Island, and across BC identify what to review before charging and filing GST.
The $30,000 Small Supplier Tests
For most businesses, the test considers worldwide taxable supplies, including zero-rated supplies, from all your businesses and those of associated persons where required. It generally excludes GST/HST itself, sales of capital property, and certain other amounts. Exempt supplies are treated differently. Special mandatory registration rules can apply, including for taxi and commercial ride-sharing services.
Exceeding $30,000 in One Calendar Quarter
You generally stop being a small supplier on the sale that takes you over $30,000. Charge GST/HST on that sale and subsequent taxable supplies, and register within 29 days of the effective date.
Exceeding $30,000 Over Four Consecutive Quarters
If no single quarter exceeds the threshold, you generally remain a small supplier through the month following the quarter in which the four-quarter total exceeds $30,000. Your effective registration date is generally the first taxable supply after you cease being a small supplier, with registration required within 29 days. This is not the same timing as the single-quarter test.
Track revenue by calendar quarter and consult CRA guidance on when to register and charge GST/HST.
Should You Register for GST in BC Voluntarily?
An eligible small supplier can choose to register before reaching the threshold. Registration may allow input tax credits for eligible GST/HST paid on expenses used in commercial activities, subject to documentation and other rules. Startup costs and property held at registration have specific treatment.
Registration also creates collection, filing, and remittance obligations, generally for at least a year before voluntary cancellation is available. Compare recoverable tax with administration and the effect on customers who cannot recover GST. Not every receipt qualifies for an input tax credit.
How to Register and Set Up
Determine whether the need to register for GST in BC is mandatory or voluntary and establish the correct effective date.
Confirm your business number and use the current CRA registration process to add the GST/HST account.
Confirm your reporting period and fiscal year.
Update invoices, accounting software, and tax coding for the supplies you make.
Keep supporting records and reserve funds for remittances.
Do not wait for paperwork before addressing tax that was legally collectible from a mandatory effective date. Similarly, do not represent yourself as registered without confirming your status.
Filing Frequency and the Quick Method
Assigned reporting periods generally follow annual taxable supplies: annual up to $1.5 million, quarterly above $1.5 million up to $6 million, and monthly above $6 million. Elections for more frequent filing may be available. Associated-person and calculation rules matter.
Annual filers may need quarterly instalments when applicable net tax thresholds are met. Filing and payment deadlines can differ for some individuals, so confirm both.
The quick method can simplify calculations for eligible businesses. The $400,000 eligibility test uses GST/HST-included taxable supplies over specified periods, with exclusions and association rules; some professions are excluded. You still keep records, charge the applicable tax, and follow special input tax credit rules. Compare methods before making an election. See the CRA registrants’ guide.
GST and PST Are Separate
BC generally uses 5% federal GST and a separate provincial sales tax, commonly 7%, with exemptions and other rates for particular items. Registering for one does not register you for the other. Place-of-supply rules can require HST on certain sales outside BC.
PST has its own registration, collection, and exemption rules and does not use the federal input tax credit system. Trades businesses can also review our BC PST guide for contractors.

Frequently Asked Questions
Does the $30,000 Include GST?
No. The small supplier calculation generally uses qualifying revenue before GST/HST.
Do Sales to US Customers Count?
Zero-rated supplies generally count toward the threshold. Not every export or cross-border service is automatically zero-rated; check the applicable rules.
What If I Registered Late?
Determine the correct effective date, tax owing, input tax credits, and outstanding returns. A CPA can assess correction options and whether a relief program applies; relief is not guaranteed.
