Quick Answer

  1. A Canadian freelancer must register for GST/HST once worldwide taxable revenue exceeds $30,000 — either in a single calendar quarter or across four consecutive calendar quarters.
  2. Cross the threshold in a single quarter and registration is required immediately, effective the day of the supply that pushed revenue past $30,000.
  3. Cross gradually across four quarters and registration is required by the end of the month following that quarter.
  4. The CRA generally allows 29 days from the effective date to complete registration.
  5. The $30,000 test is based on gross revenue from taxable supplies, not net profit, and does not include employment (T4) income.

» The moment freelance income starts to feel like a business

Freelance income climbs past $25,000, then the first invoice tips it into unfamiliar territory — most self-employed Canadians know the $30,000 GST/HST line exists, but few know when it gets crossed. The Canada Revenue Agency runs two separate tests to answer that question, and the answer changes depending on which applies.

Getting it wrong is expensive. Register late, and the CRA can require the freelancer to remit tax they never actually collected from clients. Register too early, and filing obligations start before they are needed. This guide walks through both threshold tests, the 29-day registration deadline, what counts toward the $30,000, and the six steps from crossing the line to filing a first return.

» The $30,000 rule at a glance

Direct answer. Under CRA rules, a freelancer is a small supplier when worldwide taxable revenue stays at or below $30,000 across four consecutive calendar quarters. Cross that line and small-supplier status ends. The Excise Tax Act (section 148) sets the threshold, and the CRA applies two separate tests to determine when registration is required.

The small supplier rule keeps hobby-scale earners out of full GST/HST paperwork. Once revenue climbs above $30,000, though, the CRA treats the freelancer as a full registrant — charging tax on client invoices, filing returns on a fixed schedule, and remitting the net tax collected.

Two things matter about the threshold. First, it measures gross taxable revenue, not profit — a designer who bills $32,000 and spends $10,000 on subcontractors is at $32,000, not $22,000. Second, the $30,000 is measured across a rolling 12-month window (four consecutive calendar quarters), not a fiscal or calendar year. Our guide to the new GST/HST rules for Canadian business covers broader compliance shifts.

Sole proprietor — under $30k
Generally still a small supplier and not required to register. Voluntary registration may still make sense if business expenses carry significant HST. See our self-employed tax deadline in Canada guide for related timing.
Sole proprietor — over $30k

Incorporated professional
A corporation earning freelance revenue follows the same $30,000 test, but the threshold applies at the corporation level, not personally.
Taxi or ride-share driver
GST/HST registration is required from the first dollar earned, regardless of the $30,000 threshold. The small supplier rule does not apply.

» Single quarter vs four quarters: the two tests

Direct answer. The CRA runs two separate small supplier tests. The single-calendar-quarter test triggers immediate registration on the day of the supply that pushes revenue over $30,000 within one quarter. The four-consecutive-quarter test — the more common scenario — allows registration by the end of the month following the quarter in which the cumulative total crossed.

Understanding which test applies determines whether registration is urgent or has some breathing room.

TestWhen It AppliesEffective DateGrace Period
Single Calendar QuarterRevenue in one three-month quarter alone exceeds $30,000Day of the supply that crossed $30,000None — the trigger invoice itself is taxable
Four Consecutive Calendar QuartersRevenue crosses $30,000 gradually over a rolling 12 months, without any single quarter exceeding it aloneEnd of the month following the quarter in which the cumulative total crossedAbout one month, plus 29 days to complete registration

A consultant who bills $2,000 in Q1, $10,000 in Q2, and lands a $38,000 project in Q3 fails the single-quarter test — Q3 alone is over $30,000, and HST must be charged on the invoice that pushed them over. A freelance writer billing $8,000 per quarter for a $32,000 cumulative total fails only the four-quarter test. Small supplier status ends at the end of the month following that fourth quarter, with 29 days from that date to complete registration.

» Step-by-step roadmap: from threshold to first return

Direct answer. Registering for GST/HST follows six steps: confirm the threshold has been crossed, request a Business Number from the CRA, open the GST/HST program account, choose a filing frequency, start charging HST on client invoices, and file the first return claiming input tax credits on business expenses.
  1. 1
    Confirm the thresholdAdd up gross taxable revenue for the last four consecutive quarters and check whether any single quarter alone exceeded $30,000. If either test is failed, small supplier status has ended.
  2. 2
    Request a Business Number (BN)The nine-digit CRA identifier that anchors every federal program account. Freelancers without one can apply through Business Registration Online.
  3. 3
    Open the GST/HST (RT) program accountThis account sits under the BN. Registration confirms the effective date and assigns an initial reporting period.
  4. 4
    Choose a filing frequencyThe CRA typically defaults new registrants under $1.5 million in revenue to annual filing; quarterly or monthly can be elected voluntarily.
  5. 5
    Start charging HSTFrom the effective date onward, every taxable invoice to Canadian clients needs the correct GST/HST line item — 13% in Ontario, other rates elsewhere depending on the place-of-supply rules.
  6. 6
    File the first return and claim ITCsRegistered freelancers recover GST/HST paid on legitimate business expenses through input tax credits. ClearWealth’s full services list covers GST/HST registration, filing, and dispute support.

» What counts (and what doesn’t) toward the $30,000

Direct answer. The $30,000 threshold measures worldwide taxable supplies — freelance service fees, product sales, and zero-rated exports all count. Employment (T4) income, exempt supplies like residential rent, and sales of capital property or business goodwill do not count. The test is based on gross revenue before expenses.

Taxable supplies include everything a freelancer charges GST or HST on (standard-rated), plus zero-rated supplies like most exports — where the rate applied is 0% but the transaction still counts as taxable for threshold purposes.

Exempt supplies are different. Residential rent, most financial services, and certain health and education services fall outside the GST/HST system entirely and do not count. A landlord renting only residential apartments alongside their freelance work counts only the freelance income.

Two edge cases to watch. Associated persons — including a spouse’s small business under common control — can be combined for the test in certain situations. And a freelancer with US clients still counts those invoices, because exports of services are typically zero-rated.

» Voluntary registration: when early registration pays off

Registering before hitting $30,000 is optional but often smart. It is available to any freelancer making taxable supplies in Canada and unlocks input tax credits on GST/HST paid on business expenses.

For a designer spending $8,000 a year on software, equipment, and co-working memberships — all HST-bearing — voluntary registration can recover roughly $1,040 in Ontario HST annually. That recovery goes straight to the bottom line.

The trade-off is administrative: charging HST on all Canadian client invoices, filing returns on the CRA schedule, and maintaining records for every ITC claim. When clients are themselves registrants (who recover the HST), the trade-off is often worth it. For individuals and exempt businesses who cannot recover HST, voluntary registration effectively raises the freelancer's prices. Our self-employed or incorporated: what's better in Canada guide covers the structural side.

» Common mistakes freelancers make

Five of the costliest GST/HST registration errors, all avoidable. See our incorporation vs sole proprietorship guide for related structure-side decisions.

  • ›Measuring profit instead of revenue. The $30,000 test uses gross taxable supplies, not the net income figure on the T2125. A freelancer at $45,000 revenue with $20,000 in expenses is above the threshold.
  • ›Missing the 29-day window. Late registrants may owe HST on invoices already sent — from their own pocket, not the client's.
  • ›Ignoring the taxi and ride-share exception. Drivers of taxis and commercial ride-share vehicles must register from the first dollar earned.
  • ›Forgetting associated businesses. A spouse's related business under common control may be combined with the freelancer's revenue in certain situations.
  • ›Skipping HST on the trigger invoice. When a single-quarter breach happens, the specific supply that crossed $30,000 is itself taxable — HST goes on that invoice, not the next one.

» Frequently asked questions

Do I have to charge HST if I make less than $30,000 freelancing?

Not typically. A freelancer with worldwide taxable revenue at or below $30,000 across four consecutive calendar quarters — and no single quarter exceeding that limit — remains a small supplier and is not required to register or charge HST.

Is the $30,000 GST/HST limit based on revenue or profit?

Revenue. The CRA measures the threshold on gross worldwide taxable supplies before expenses. A freelancer earning $40,000 with $15,000 in business expenses is at $40,000 for the test, not $25,000. This is the most common misconception in registration timing.

How long do I have to register for GST/HST after I go over $30,000?

Generally 29 days from the effective date. For a single-quarter breach the effective date is the day of the trigger supply; for a gradual breach it is the end of the month following the quarter that crossed the threshold.

What happens if I don’t register for GST/HST on time?

The CRA can require the freelancer to remit HST on invoices sent after the effective date, even if the tax was never collected from the client. Interest and penalties may apply. The Voluntary Disclosures Program may help fix late registration.

Do I need to charge HST on invoices to US or overseas clients?

Not typically. Exports of services to non-resident clients are usually zero-rated (0% rate applied). No HST is charged on the invoice, but the revenue still counts toward the $30,000 threshold test.

Should I register for GST/HST voluntarily before I hit $30,000?

Often yes when business expenses carry significant HST and clients are themselves registrants who recover HST. Less attractive when clients are individuals who bear the HST as a real cost, since it effectively raises the freelancer's prices.

Does my full-time job salary count toward the $30,000 threshold?

No. Employment income reported on a T4 slip is not a taxable supply for GST/HST purposes and does not count toward the $30,000 threshold. Only revenue from freelance and other commercial activity counts.

What HST rate do I charge if I’m in Ontario but my client is in Alberta?

Place-of-supply rules apply, not the freelancer's home province. For services delivered to a business address in Alberta, the rate is generally 5% GST rather than Ontario's 13% HST.

» Bottom line: get it right the first time

Getting GST/HST registration right early — before the CRA has to correct it — is often the difference between a smooth compliance year and an unwelcome reassessment. The two threshold tests, the 29-day window, and the ride-share exception cover almost every freelancer situation, but the edge cases are where costly mistakes typically hide.
