CRA Compliance Desk · Canadian Sole Proprietor & T2125 Rules
Under Canada Revenue Agency (CRA) rules for "Canada & Québec IT Consultant & Developer T2125 + GST/QST", sole proprietors exceeding the C$30,000 Small Supplier threshold across four consecutive calendar quarters must register for a 15-digit RT GST/HST account, charge provincial GST/HST (5% GST in AB/BC/SK/MB, 13% HST in ON, 14% in NS, 15% in NB/NL/PE), and remit net tax after claiming Input Tax Credits (ITCs) or using the GST/HST Quick Method.
Key Takeaways
- C$30,000 GST/HST Rule: Below C$30,000 in 4 consecutive quarters you are a Small Supplier; once exceeded, register within 29 days and display your 9-digit BN + RT0001 on every invoice.
- T2125 & Dual CPP: Self-employed Canadians contribute 11.9% to base CPP on net earnings between the C$3,500 exemption and the annual YMPE ceiling (50% deductible on Line 22200).
- Key CRA Deadlines: T1/T2125 filing is due June 15 for self-employed individuals and spouses, but any balance owing must be paid by April 30 to avoid daily compound interest.
“Use Form T2125, Statement of Business or Professional Activities, to report your business or professional income and expenses, and keep your supporting receipts and logbooks for six years from the end of the last tax year to which they relate.”
Canada & Québec IT Consultant, Software Developer & Web Designer Tax Guide: CRA T2125, Revenu Québec TP-80-V & 0% US Export GST/QST (2026)
Short answer: Under CRA Form T2125, Revenu Québec Form TP-80-V, and the Excise Tax Act (Schedule VI, Part V, s. 7), this canada quebec it consultant software developer t2125 gst qst guide covers three high-value rules: billing US or foreign tech clients is a 0% zero-rated export, meaning you charge 0% GST/HST/QST while claiming 100% Input Tax Credits (ITCs) and Input Tax Refunds (ITRs) as cash refunds on MacBook Pros and SaaS tools; computers fall into CCA Class 50 (55%); and every $100 in missed receipts costs $32 to $48 in extra tax.

Why do Canadian & Québec software developers billing US clients get cash GST/HST and QST refunds from the CRA & Revenu Québec?
Thousands of independent full-stack developers, DevOps/cloud architects, UI/UX designers, Shopify/Webflow consultants, and AI engineers in Toronto, Montréal, Vancouver, Calgary, and Ottawa work remotely for US startups, Delaware C-Corps, or UK/EU SaaS companies via Deel, Wise, Stripe, or wire transfer.
Many assume that because their US clients don’t pay Canadian sales tax, they shouldn’t register with the Canada Revenue Agency (CRA) for a GST/HST (RT0001) or QST (TQ0001) account—or that their $30,000 Small Supplier threshold only counts Canadian clients. Both assumptions cost thousands of dollars:
- Zero-Rated Exports (
0%Tax Charged,100%ITCs/ITRs Refunded): Under Excise Tax Act Schedule VI, Part V, section 7 (and Act respecting the Québec sales tax s. 179), intangible software development, IT consulting, cybersecurity, and web design supplied to a non-resident client (who is not registered for GST/HST and is outside Canada when the service is performed) is zero-rated (0%), not exempt.- Because zero-rated supplies are taxable supplies at
0%, your US revenue counts toward the$30,000four-quarter registration threshold! - Even better: once registered (mandatory over
$30,000—or voluntarily from$0!), you charge your US client0%GST/HST/QST, collect$0in sales tax, and file a GST/HST & QST return claiming 100% of the13%HST (Ontario) or14.975%GST+QST (Québec) you paid on your$4,000MacBook Pro, Apple Studio Display, AWS/Cursor/GitHub Copilot subscriptions, coworking desk, and accountant fees—receiving a direct cash refund deposit from the CRA and Revenu Québec!

| IT Consultant & Developer Expense | CRA T2125 Line | Revenu Québec TP-80-V Line | 2026 Statutory Rule + ITC / ITR Recovery |
|---|---|---|---|
Cloud hosting (AWS, Vercel, Cloudflare), AI APIs (OpenAI, Anthropic, Cursor), GitHub, Figma, Linear | Line 8810 (Office stationery and supplies) or Line 9270 (Other expenses) | Line 236 / 250 (Frais de bureau / Autres dépenses) | 100% deductible; convert USD card charges using the Bank of Canada daily exchange rate on the date of each transaction (or annual average rate for recurring monthly SaaS) |
| Subcontracted freelance developers, QA testers, UI designers & copywriters | Line 8360 (Subcontracts) | Line 191 (Sous-traitance) | 100% deductible; claim 100% ITC/ITR if your Canadian subcontractor is GST/HST/QST registered and lists their RT/TQ number |
| MacBook Pro, Linux workstation, monitors, iPhones, routers & NAS drives | Line 9936 (Capital Cost Allowance — CCA Class 50) | Line 240 (Amortissement — Catégorie 50) | CCA Class 50 (55% declining balance rate) for general-purpose electronic data-processing equipment & system software; 100% of GST/HST/QST (ITC/ITR) is refunded in Year 1 on the first GST/QST return! |
Ergonomic chair (Herman Miller), standing desk & studio furniture | Line 9936 (CCA Class 8) | Line 240 (Catégorie 8) | CCA Class 8 (20% declining balance rate); 100% of GST/HST/QST paid is recovered immediately via ITC/ITR |
Coworking membership (WeWork, Spaces, Crew Collective) | Line 8910 (Rent) | Line 228 (Loyer) | 100% deductible + 100% ITC/ITR recovery |
Errors & Omissions (E&O / Cyber Liability) insurance | Line 8690 (Insurance) | Line 223 (Assurances) | 100% deductible (no GST/HST applies to insurance premiums, though Québec 9% tax on insurance premiums is deductible as part of the expense on T2125/TP-80-V) |

Should a Canadian IT consultant with domestic Canadian clients use the CRA GST/HST Quick Method (Form GST74)?
If your clients are primarily Canadian companies (where you charge 13% HST in Ontario or 5% GST + 9.975% QST in Québec) and your annual software/hardware overhead is low, the CRA GST/HST Quick Method (Form GST74) (and Revenu Québec FP-2074-V) is a massive legal profit booster:
- In Ontario (
13%HST charged to clients): Under the Quick Method for service businesses, you collect13%HST from your client ($13,000on$100,000of fees), remit only8.8%($8,800) less the1%credit on your first$30,000(-$300=$8,500remitted), and legally pocket the remaining$4,500, plus you still claim full13%ITCs on capital hardware like a new MacBook Pro! - When NOT to use the Quick Method: If most of your clients are US or foreign companies (
0%zero-rated), stick with the Regular GST/HST & QST Method—because you collect$0in tax on US exports and want to claim100%ITCs/ITRs on every operational SaaS and office expense.
How to avoid the CRA “Personal Services Business (PSB)” trap vs unincorporated T2125 sole proprietorship
Many Canadian IT contractors incorporate (Inc.) for a single full-time contract with a bank, telecom, or government ministry, only to be audited by the CRA as a Personal Services Business (PSB — entreprise de prestation de services personnels), which loses the Small Business Deduction and faces a punitive 44.5%+ corporate tax rate with almost zero expense deductions.
Operating as an unincorporated sole proprietor (T2125 / TP-80-V) or serving multiple clients with your own MacBook, your own E&O insurance, milestone/deliverable invoicing, and the right to subcontract documents genuine self-employment under the CRA’s four-point Wiebe Door / Sagaz test (control, ownership of tools, chance of profit/risk of loss, integration).

Frequently asked questions
Do I charge GST, HST, or QST to a US client when I code from Toronto or Montréal?
No. Under Excise Tax Act Schedule VI, Part V, section 7 and QST Act s. 179, software engineering, IT consulting, and web design services supplied to a non-resident US or foreign client (who is outside Canada and not GST/HST registered) are zero-rated (0%). Write "Zero-rated export of services — ETA Sch. VI, Part V, s. 7 (0% GST/HST / 0% QST)" on your invoice.
How do I convert USD client payments from Stripe, Wise, or Deel on CRA Form T2125?
The CRA requires all income and expenses on Form T2125 (and Revenu Québec TP-80-V) to be reported in Canadian dollars (CAD). If a US client pays into a USD bank or Wise account, convert the gross invoice amount using the Bank of Canada daily exchange rate on the day the payment was earned/received (if converted immediately into CAD by Stripe or your bank, use the actual CAD settlement amount, and deduct any FX/Stripe processing fee on Line 8710 Interest and bank charges or Line 8871 Management/platform fees).
Does zero-rated US tech revenue count toward the $30,000 GST/HST and QST threshold?
Yes! Because zero-rated exports are taxable supplies taxed at 0%, 100% of your US/foreign consulting revenue counts toward the $30,000 Small Supplier threshold over four consecutive calendar quarters. Once you pass $30,000 worldwide taxable revenue, you must register for GST/HST (and QST in Québec)—which works in your favour because registration lets you claim cash refunds (ITCs/ITRs) on all Canadian business purchases while still charging US clients 0%.
Can I claim 100% of a new MacBook Pro in Year 1 on T2125?
Computer hardware and system software fall under CCA Class 50 (55% declining balance rate). For eligible capital property acquired by unincorporated sole proprietors or eligible businesses, you claim CCA on Form T2125 Area A (multiplied by your business-use percentage), while 100% of the GST/HST and QST paid on the MacBook Pro is refunded immediately on your very next GST/HST & QST filing!
What must appear on a Québec (TP-80-V) IT consultant invoice?
For Canadian clients, include your legal name or registered business name (NEQ if registered on the Registraire des entreprises), sequential invoice number, service dates/sprint milestones, pre-tax subtotal, 5% GST with your 15-character GST number (123456789 RT0001), and—for Québec clients—9.975% QST with your 16-character QST number (1234567890 TQ0001).
