GST is not your money, and the CRA treats it that way. What you remit is the tax you collected on sales minus the input tax credits you paid on business expenses, so accurate expense tracking directly reduces what you owe. Registration is mandatory once taxable revenue passes $30,000 over four consecutive quarters, and it is often worthwhile before that so you can recover the GST you pay.
We prepare and file your GST returns on your assigned schedule, reconcile the collected tax and input credits to your books, and check whether the Quick Method would leave you better off — for a low-expense service business it frequently does, plus a 1% credit on the first $30,000 of eligible sales. We also catch the common errors: the wrong place-of-supply rate, treating exempt supplies as if credits were recoverable, and forgetting that exports are generally zero-rated.

GST registration is not optional once you cross the small supplier threshold of $30,000 in taxable revenue over four consecutive calendar quarters, and the obligation begins immediately, not at the next year-end. The trap is retroactive: a business that passes the threshold and keeps invoicing without GST still owes the tax it failed to charge, out of its own margin. Voluntary registration before the threshold is often worth it for businesses with large startup input tax credits to recover.
If you handle GST Returns once a year, everything looks equally important. Handle it weekly, as a tax professional does, and a clear hierarchy emerges; these notes follow that hierarchy.
If a client remembers only one point from this page, it should be this one: 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.
It would be simpler if the story ended there, but a second rule enters almost immediately. The rate charged follows the customer's province, not the seller's: 13% into Ontario, 15% into the Atlantic provinces, 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: 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.
For you, the takeaway is less about memorizing rules and more about timing the conversation. Bringing a tax professional in early on gst returns means the rules shape the file instead of correcting it. Here is what to have on hand so the gst returns work starts moving on day one.

A marketing agency billing outside its home province in Regina, Saskatchewan was 8 weeks from a deadline while carrying a sales tax account filed annually while the CRA had moved the business to quarterly. Filing complete and on time avoided roughly $17,000 in penalties.
An incentive review at a seller who crossed the registration threshold before registering in Barrie, Ontario found nil periods left unfiled, which held up the refund on the one period that mattered and recovered $46,000 across 3 open years.
The ledger at a used-equipment dealer in Vancouver, British Columbia could not support its own filings because of input tax credits claimed on the exempt side of a mixed-supply business. Rebuilding it surfaced $7,000 in unclaimed input tax.
A family transfer at a health clinic making exempt supplies in Surrey, British Columbia would have been fully taxable because of a single shareholder holding every share, with no room to multiply the exemption. Restructuring deferred $775,000.
A restaurant group in Kitchener, Ontario was overpaying instalments because of HST charged at the home-province rate on sales into four different provinces. Rebasing them returned $108,000 to the business.
Collections had begun against a platform seller collecting tax at checkout in Kelowna, British Columbia over 4 years of unfiled returns. Bringing them current cut $98,000 from the balance.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
GST Returns 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 support 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 are a cloud-based practice serving every province and territory, 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.

The honest starting point is this: Closely related registrants can elect under section 156 to treat supplies between them as made for nil consideration, but the election has to be filed with the CRA rather than signed and left in the minute book. An unfiled election means the inter-company charges were taxable all along. Everything else we would tell you is tailoring, and tailoring requires seeing your file.
Zero-rated exports carry a 0% rate but still require proof the goods left Canada. Without export documentation the CRA reassesses the sale at the domestic rate. 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.

Multiply the pre-tax price by the rate for the province of supply. On a $100 purchase in 2026 that is $13.00 in Ontario (13%), $14.00 in Nova Scotia (14%), and $15.00 in New Brunswick, Newfoundland and Labrador or Prince Edward Island (15%). In the non-participating provinces and the three territories only the 5% GST applies, so $5.00, plus any provincial sales tax billed separately.
The route depends on the structure. A sole proprietor or partner reports business income on Form T2125 and files it with the personal T1 return; for the 2025 year the self-employed filing deadline was 15 June 2026, while any balance owing was due 30 April 2026. An incorporated business files a separate T2 corporate return for each fiscal year, due six months after that year end, on top of whatever the owner reports personally.
HST in Nova Scotia is 14% in 2026. The province cut it from 15% on 1 April 2025 by lowering its own component from 10% to 9%; the federal 5% GST part was unchanged. Nova Scotia is the only jurisdiction at 14%, so the Atlantic provinces are no longer on one rate. Under the transitional rules, amounts that became payable before 1 April 2025 were still subject to 15%.
Three different calculations go by that name. For sales tax, multiply the price by the harmonised rate that applies to the province of supply. For income tax, apply the federal brackets and then the Ontario brackets to taxable income and subtract your credits. For payroll, the CRA payroll deductions calculator handles income tax withholding along with CPP and EI for each pay period. Look up the rates and brackets published for the year you are calculating, since they change annually.
Taxable sales are your revenue from goods and services that GST/HST applies to, counted before the tax is added. Zero-rated sales, taxed at 0%, still count as taxable; exempt supplies such as most long-term residential rent and many health services do not. Add the taxable amounts over four consecutive calendar quarters to test the $30,000 small-supplier threshold for 2026, unchanged from 2025. Cross it inside a single quarter and small-supplier status ends on the sale that takes you over.
No. Quebec sits outside the HST system. You charge the 5% federal GST plus Quebec sales tax at 9.975%, applied to the pre-GST price, for a combined 14.975%. The two are reported separately, and QST is generally administered by Revenu Quebec rather than the CRA. If you sell into Quebec from another province, check on the Revenu Quebec site whether you must register for QST as well as GST/HST.
Often, yes. A first return has no filing history behind it, so the CRA may verify your identity, address and date of birth before assessing it, and setting up direct deposit for the first time adds a step. Once assessed, timing matches any other return: about two weeks for one filed online. Opening My Account and registering direct deposit before you file removes most of the delay.
Some provinces do. British Columbia charges 7% PST and Saskatchewan 6%, both on top of the 5% GST. Manitoba charges 7% RST, and Quebec charges 9.975% QST on the pre-GST price, for 14.975% combined. Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador and Prince Edward Island fold the provincial part into HST instead. Alberta and the three territories charge the 5% GST only, with no provincial sales tax.
Canada has no tax called VAT. The equivalent is GST at 5% for 2025 and 2026, combined with the provincial part as HST in Ontario at 13%, Nova Scotia at 14% since 1 April 2025, and New Brunswick, Newfoundland and Labrador and Prince Edward Island at 15%. Other provinces add a separate provincial sales tax or Quebec's QST. Foreign VAT you paid abroad cannot be recovered through a Canadian GST/HST return.
Land transfer tax is provincial and is charged on the purchase price, usually on a graduated scale, so the cost depends on the province and the price. Buyers in Toronto pay a municipal land transfer tax on top of Ontario's. Alberta, Saskatchewan and the territories charge registration or transfer fees instead of a full tax. Several provinces offer first-time buyer rebates, and non-resident buyers can face extra tax. Use your province's own calculator before closing.
It is a quarterly payment for lower and modest income residents of Canada for tax purposes, and you get it by filing a return; for most people there is no separate application. Eligibility turns on the CRA's age and family conditions, broadly an adult, or younger if you have a spouse, common-law partner or a child living with you. The amount depends on family net income and the number of children, so both spouses must file.
Basic groceries are zero-rated, so no GST/HST applies to items such as milk, bread, vegetables, meat and eggs. Tax does apply to restaurant meals, most prepared and heated foods, snack foods, candy, carbonated drinks and food sold from vending machines. The rate charged on those taxable items depends on the province of supply, so the combined rate in your province decides what lands on the receipt.
