Registration becomes mandatory once taxable supplies pass $30,000 over four consecutive calendar quarters. We quote e-commerce sales-tax compliance as one affordable fixed price — the budget-friendly alternative to hourly billing.
Every week brings another round of e-commerce sales-tax compliance work, and every week the same few issues account for most of the friction. Consider this a working accountant's short list for E-commerce Sales-Tax Compliance.
There is no way around the opening fact, so it may as well come first. Registration is mandatory once taxable supplies pass $30,000 over four consecutive calendar quarters. Input tax credits require documentation that scales with invoice size. Unmatched input tax credits are the first thing disallowed in a sales-tax review, and the assessment covers every period reviewed.
Pair that with the next rule and most of the confusion around e-commerce sales-tax compliance disappears: The rate charged follows the customer's province, not the seller's: 13% into Ontario, 15% into New Brunswick, Newfoundland and Labrador and PEI, 14% into Nova Scotia (since 1 April 2025), 5% plus provincial tax elsewhere. A seller charging its own province's rate nationally is under-collecting on some sales and over-collecting on others, and owes the difference on the under-collected ones. The final point is less about opportunity and more about what happens when a file is challenged: British Columbia, Saskatchewan and Manitoba run their own sales taxes alongside GST, filed separately, and unlike GST they are generally not recoverable as input credits. Businesses expanding into a PST province routinely register late, and the province assesses from the date the obligation started, not the date of registration.
In practice, this is why e-commerce sales-tax compliance rewards an accountant rather than a generic preparer: each of these points is a judgement call before it is a keystroke. Think of this list as the raw material an accountant works from on e-commerce sales-tax compliance.
Whatever the file involves, the terms do not change: fixed fee agreed up front, review together before filing, payment after the service.

Collections had begun against a restaurant group in Guelph, Ontario over 5 years of unfiled returns. Bringing them current cut $87,000 from the balance.
By the time a restaurant group in Guelph, Ontario called, 5 years were outstanding. The CRA had assessed on estimates. Underneath it sat a sales tax account filed annually while the CRA had moved the business to quarterly. We reconstructed the records year by year. We filed the section 156 election for the related registrants, so supplies between them stopped carrying tax that served no purpose but cash-flow drag. Each filing replaced an arbitrary assessment with a real one. The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $87,000, and a relief application addressed part of the accumulated interest.
A $37,500 reassessment was proposed against a professional practice with exempt and taxable supplies in Vancouver, British Columbia. It followed a registration threshold crossed nine months before anyone registered. The documented response reduced it to nil.
A review notice arrived at a professional practice with exempt and taxable supplies in Vancouver, British Columbia, covering e-commerce sales-tax compliance for two tax years. The auditor's working position was an adjustment of $37,500. It was driven by a registration threshold crossed nine months before anyone registered. Rather than negotiate, we rebuilt the record. We assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment. We then submitted a point-by-point response that answered each proposed adjustment with the document behind it. The auditor accepted the documented position and closed the review without adjustment, protecting $37,500 and leaving the prior filings undisturbed.
A health clinic making exempt supplies in Winnipeg, Manitoba was profitable and permanently short of cash. Behind the gap sat a commercial property purchase closed on the assumption no tax applied because the vendor was not registered. Restructuring the tax cycle freed $81,000.
A health clinic making exempt supplies in Winnipeg, Manitoba was profitable on paper and short of cash every month. A commercial property purchase closed on the assumption no tax applied because the vendor was not registered explained most of the gap. We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars. $81,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
A $22,500 reassessment landed at a construction supplier selling into three provinces in Saskatoon, Saskatchewan. It rested on export sales zero-rated with no shipping documentation behind them. The objection was allowed in full.
A construction supplier selling into three provinces in Saskatoon, Saskatchewan had been reassessed for $22,500. 20 days were left on the objection deadline. The reassessment rested on export sales zero-rated with no shipping documentation behind them. We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, we backdated the registration to the date the business stopped being a small supplier, remitted the tax owing, and applied for relief on the penalty portion. The appeals officer allowed the objection in full. $22,500 was reversed and the account returned to a nil balance.
A family transfer at a marketing agency billing outside its home province in Regina, Saskatchewan would have been fully taxable. The reason was a shareholder loan balance that would have been picked up as income on closing. Restructuring deferred $280,000.
A generational transfer at a marketing agency billing outside its home province in Regina, Saskatchewan had been discussed for years without a plan. A shareholder loan balance that would have been picked up as income on closing meant the transfer as contemplated would have been fully taxable. We rebuilt the sales ledger by customer province and applied the correct place-of-supply rate to each stream. We filed corrected returns before the CRA opened a review. We sequenced the steps so each one was complete and documented before the next depended on it. $280,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
Growth at a freight brokerage in Windsor, Ontario had outrun the back office. Management fees between two related registrants carrying tax that only ever went out and came back broke first. Headcount reached 35 with $103,000 of cash freed.
A freight brokerage in Windsor, Ontario was growing fast, with headcount reaching 35 in eighteen months. The back office had not kept up. Management fees between two related registrants carrying tax that only ever went out and came back was the first thing to break. We tested the quick method against the account’s actual input tax credit history and stayed on the regular method where the credits were worth more. We built the compliance calendar for the size the business was becoming rather than the size it had been. The business reached 35 staff with no missed remittance and no late filing. $103,000 of working capital was freed in the process.

Same fixed fees in every province. Find your city or your sector.
Direct answers to what Canadian business owners actually ask before hiring an accountant.
E-commerce Sales-Tax Compliance starts at a fixed fee quoted before any work begins. The quote is locked at the outset and does not change mid-engagement, and you pay only after you have reviewed and approved the deliverable. Compare every plan on our transparent pricing page.
At minimum: prior-year returns and notices of assessment, your bank and credit-card statements for the fiscal period, payroll records if you have employees, and GST/HST filings. We send a checklist tailored to your situation after the free 15-minute call.
Most engagements are completed within 3 to 5 business days once your documents are complete. Catch-up work covering multiple years takes longer, and we tell you the realistic timeline before you commit rather than after.
We respond on your behalf at no extra charge for any return we prepared. Every figure we file is supported by documentation retained in your file, which is what turns a CRA review from a crisis into correspondence. See how our CRA audit representation works.
Yes. Late filing penalties compound at 5% of the balance owing plus 1% per month, so the cost of waiting is real. We prioritise catch-up work and, where eligible, file under the CRA's Voluntary Disclosures Program to reduce penalties.
Yes. We serve clients in every province and territory at the same fixed fees, so your location does not change the price or the service. Browse our coverage across Canada to find your city.
We work across construction, healthcare, e-commerce, professional services, restaurants, real estate, transportation, technology and non-profits, each with its own deduction profile and CRA scrutiny patterns. See all industries we serve.
Software applies the rules you already know about. An experienced tax accountant finds the ones you do not: capital cost allowance timing, the small business deduction threshold, shareholder loan repayment rules, and TOSI exposure on family dividends. The fee is usually smaller than the deductions it surfaces.
Our e-commerce sales-tax compliance services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

There is a widespread assumption here, and the actual position is worth stating plainly. British Columbia, Saskatchewan and Manitoba run their own sales taxes alongside GST, filed separately, and unlike GST they are generally not recoverable as input credits. Businesses expanding into a PST province routinely register late, and the province assesses from the date the obligation started, not the date of registration. If your current setup was built on the assumption instead of the rule, that is fixable — but sooner is better than later.
The rate charged follows the customer's province, not the seller's: 13% into Ontario, 15% into New Brunswick, Newfoundland and Labrador and PEI, 14% into Nova Scotia (since 1 April 2025), 5% plus provincial tax elsewhere. A seller charging its own province's rate nationally is under-collecting on some sales and over-collecting on others, and owes the difference on the under-collected ones. We flag this early with every client it touches, because finding it out at filing time leaves you far fewer options than finding it out now.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
Sales tax in Ontario is 13% HST for 2026, made up of the 5% federal GST and an 8% provincial share, and it has applied at that rate since 1 July 2010. There is no separate Ontario retail sales tax on top, and the CRA administers the whole 13%. Basic groceries and prescription drugs are zero-rated, so they carry nothing. Income tax is a separate calculation with its own federal and Ontario brackets.
Sales tax in British Columbia totals 12% for 2026: the 5% federal GST plus 7% provincial sales tax. BC is not harmonised, so the two run separately, with GST registered and filed with the CRA and PST with the province. A $100 taxable sale carries $5 GST and $7 PST. PST has its own exemptions, including most food for human consumption, so some sales take the 5% GST only.
Yes. Canada's value-added tax is GST/HST. GST is 5% federally in 2025 and 2026. In participating provinces it is combined into HST: 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia since 1 April 2025. Registered businesses charge it on taxable sales and claim input tax credits on what they pay, so the tax lands on the final consumer.
A tax return reports a calendar year of income and settles your account with the CRA. You file a T1, list the income from your slips along with any self-employment or investment income, claim deductions and credits, and the return calculates the tax owed. Tax already withheld from your pay is credited against that figure, leaving either a refund or a balance to pay. For the 2025 tax year the deadline was 30 April 2026, and an online return for that year is usually processed in about two weeks.
The business number is the single identifier the CRA uses for your business, with a separate programme account opened under it for each obligation: GST/HST, payroll deductions, corporate income tax, import and export. Register through Business Registration Online, by phone or by mail, or receive one automatically when you incorporate federally. You need it before you can remit payroll or file GST/HST. Provincial registration is separate in some provinces, notably Quebec, where Revenu Québec administers its own accounts.
Canada's value-added tax is the GST/HST, so read VAT-exempt as GST/HST-exempt. The supplier charges no tax on the sale and cannot recover the tax it paid on inputs used to make that sale, which is the part people miss: the embedded tax stays buried in the price. Health care, child care, long-term residential rent and most financial services sit here. Zero-rated is the better position, still taxable but at 0%, with input tax credits fully recoverable.
No. GST/HST you collect is not revenue: you hold it on the CRA's behalf and remit it. Report sales net of the tax on your T2125 or corporate financial statements, and post the tax collected to a liability account rather than income. Including it overstates both revenue and profit. If you are not registered and charge no tax, gross sales are simply the amounts you billed your customers.
Yes. Tattooing is a taxable service, so GST/HST applies at the rate where the studio operates: 5% GST alone in Alberta, 13% HST in Ontario, and 14.975% combined in Quebec, where QST applies to services broadly. The provinces with a separate PST tax only listed services, so check the provincial bulletin. An artist under the $30,000 small-supplier threshold need not register or charge tax at all.
Sign in to CRA My Account and open the section for your returns, where assessed returns, notices of assessment and reassessment notices are held for several years. You can also request a proof of income statement, ask the CRA by phone for copies, or ask whoever prepared the return for their file copy. Keep your own records six years from the end of the last tax year they relate to.
Car insurance premiums carry no GST or HST. Insurance is treated as a financial service, and financial services are exempt supplies, so no federal or harmonized tax is added to the premium. Some provinces levy their own tax on certain insurance premiums, which is a provincial charge rather than GST/HST and cannot be recovered as an input tax credit. Repair invoices from a garage are a different matter and are taxed in the normal way.
No. Canada has no joint return. Each spouse or common-law partner files a separate T1 reporting only their own income. What changes is the identification page: you tick married or common-law and give your partner's name, social insurance number and net income, which opens up couple-level credits and sets the income used for benefits. Most couples still prepare the two returns side by side so donations, medical expenses and pension splitting land on the better return.
Rent paid on your own home is not deductible on the federal return, so most tenants report nothing. Rent does belong on the return in three cases: you are claiming a provincial benefit that is based on rent, such as the Ontario energy and property tax credit or the Manitoba renters tax credit; you are deducting a work-space-in-the-home share as an employee or a self-employed person; or you received rent as a landlord, which is taxable income.
