CRA reviews are won on documentation: every figure filed should trace to a source document, and deadlines — 90 days for an objection — are unforgiving. Registration becomes mandatory once taxable supplies pass $30,000 over four consecutive calendar quarters. Our gst/hst audit support engagement is priced as a economical flat fee, so the cost is known before the work starts.
Before you hand gst/hst audit support to anyone, it is worth knowing what the work actually turns on.
The first thing we verify on every engagement: 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.
That rule rarely travels alone; alongside it sits another: 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. A file is only as strong as what backs it up, which brings us to the next rule: 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.
You do not need to hold all of this in your head. You need someone who does — and a tax practitioner handling gst/hst audit support week after week keeps these rules current so you do not have to. Every gst/hst audit support file rests on documentation, so start by collecting.
The fee is fixed and agreed before any work starts, you review every figure, and payment happens only after the work is done.

A residential landlord also renting commercial space in Barrie, Ontario was filing correctly and still overpaying. The reason was input tax credits claimed on the exempt side of a mixed-supply business. Restructuring the position cut $26,500 from the annual bill.
A residential landlord also renting commercial space in Barrie, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left input tax credits claimed on the exempt side of a mixed-supply business on the table. We modelled the current position against the alternatives before changing anything. Then we set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. The change saved $26,500 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
A desk review assessed a health clinic making exempt supplies in Kelowna, British Columbia $124,000. The dispute was over a sales tax account filed annually while the CRA had moved the business to quarterly. Producing the records vacated the assessment.
A health clinic making exempt supplies in Kelowna, British Columbia was carrying $124,000 of penalties and interest. The charges arose from a sales tax account filed annually while the CRA had moved the business to quarterly. Much of that amount accumulated during a period the CRA itself had delayed. We brought the nil and missing periods current so the account was clean before the refund claim was filed. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship. The assessment was vacated. $124,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
An incentive review at a multi-province online retailer in Guelph, Ontario recovered $102,000 across 7 open years. It found input tax credits claimed on the exempt side of a mixed-supply business.
An incentive review at a multi-province online retailer in Guelph, Ontario started from a simple question: what has never been claimed? The answer ran to 7 years. It was driven by input tax credits claimed on the exempt side of a mixed-supply business. We assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires. The credits produced $102,000 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
A SaaS company with Canadian and US customers in Lethbridge, Alberta was overpaying instalments. The cause was HST charged at the home-province rate on sales into four different provinces. Rebasing them returned $84,000 to the business.
A SaaS company with Canadian and US customers in Lethbridge, Alberta was paying instalments calculated on a prior year. That year no longer reflected the business. HST charged at the home-province rate on sales into four different provinces was tying up $84,000 of cash. We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, 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. $84,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
A marketing agency billing outside its home province in Toronto, Ontario needed a holding structure. It had to deal with export sales zero-rated with no shipping documentation behind them. The reorganisation was tax-neutral and removed $31,500 of annual exposure.
The structure at a marketing agency billing outside its home province in Toronto, Ontario needed fixing. The file was carrying export sales zero-rated with no shipping documentation behind them. Every option for fixing it ran through a reorganisation that had to be done without triggering tax. We worked with the client's lawyer. Together, 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. We also prepared the elections, resolutions and valuations the structure needed to stand up. The structure now matches the business. Annual saving of $31,500, and the reorganisation itself was tax-neutral.
A restaurant group in Calgary, Alberta faced a $60,000 proposed reassessment. It came after management fees between two related registrants carrying tax that only ever went out and came back. We rebuilt the documentation and the adjustment was withdrawn in full.
A restaurant group in Calgary, Alberta received a proposal letter opening a review of GST/HST audit support. The CRA had identified management fees between two related registrants carrying tax that only ever went out and came back. It proposed an adjustment of $60,000, with 30 days to respond. We treated the response as an evidence exercise rather than an argument. 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 then indexed every supporting document against the specific line the auditor had questioned. The proposed adjustment was withdrawn in full — all $60,000 of it. The file closed in 4 weeks with no change to the assessed amounts and no penalty.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
GST/HST Audit Support 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 gst/hst audit support services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

Let us give you the substance first and the caveats second. Closely related registrants can elect under section 156 to treat supplies between them as made for nil consideration. 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. The caveat is simply that facts on your file can shift the outcome, so treat this as the baseline rather than the final word.
An accounting firm answers this differently than a search engine, because the rule has edges. A sale of real property is taxable unless an exemption applies. The vendor not being registered does not make it tax free. A purchaser that is a registrant acquiring the property for use in a commercial activity self-assesses the tax. It does so on its own return instead of paying the tax to the vendor. Where your business sits relative to those edges is what we establish in the first meeting.

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.
Canada runs three systems. The federal GST is 5% for 2026 and applies nationally. Five participating provinces fold a provincial share into one harmonised rate: 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia since 1 April 2025. Others add their own tax to the 5% GST, giving 12% in British Columbia and Manitoba, 11% in Saskatchewan and 14.975% in Quebec. Alberta and the territories charge 5% only.
Long-term residential rent is exempt, so a landlord charges no GST/HST on it and cannot claim input tax credits on the related costs. Commercial and office rent is taxable at the rate for the province: 5% GST, or the HST rate where HST applies. Short-term accommodation is generally taxable as well. Exempt is not zero-rated, because zero-rated supplies are taxed at 0% but still allow input tax credit recovery. Confirm the treatment before setting rents.
The usual route is online banking: add the CRA as a payee, choose the account type and the tax year, and pay as you would any bill. You can also use the CRA's My Payment service with a debit card, set up pre-authorised debit inside My Account, pay at your financial institution, or pay by credit card through a third-party provider that charges its own fee. Keep the confirmation, since payments do not always post to your CRA account immediately.
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%.
Severance is employment income in the year you receive it, so it is added to your other income and taxed at your marginal rates. The employer withholds at lump-sum rates, which are often lower than the rate you end up at, so a balance can be owing when you file. Part of a retiring allowance can sometimes be transferred straight to an RRSP within your available room, deferring the tax. Sort this out before the payment is issued.
No. British Columbia exempts books from PST, so a printed book normally carries only the 5% GST. The exemption is aimed at printed books carrying an International Standard Book Number, and newspapers and qualifying magazines get similar treatment. Audiobooks, e-books and digital subscriptions are handled differently, so check the province's PST exemption bulletin for those. The GST still applies either way, and no provincial tax is added at the till.
No. Insurance is treated as a financial service for GST/HST purposes, so the premium on an auto policy is exempt and carries no GST or HST. Some provinces charge their own tax on certain insurance premiums, which is why a policy can still show a tax line. GST/HST does apply to related taxable supplies such as repair labour, parts and a rental car, even when the insurer pays the invoice. The CRA's financial services guidance sets out the boundary.
For an unincorporated business the 2025 return was due 15 June 2026 because of self-employment, but any balance owing had to be paid by 30 April 2026. For an incorporated business the T2 return is due six months after the fiscal year end, with the balance due two months after year end, or three months for an eligible Canadian-controlled private corporation claiming the small business deduction. GST/HST returns and payroll remittances run on their own separate schedules.
Tea you buy to brew at home is a basic grocery, so it is zero-rated and no GST or HST is charged on tea bags, loose leaf or instant tea powder. A cup of tea served ready to drink at a cafe, restaurant or vending machine is a prepared beverage and is taxable at the rate for that province. Bottled iced tea in a single serving is taxable too. The CRA's basic groceries guidance sets out the dividing lines.
That figure is your payroll deduction rate, not a tax bracket. Canada's federal rates for 2026 start at 14% and rise through 20.5%, 26% and 29% to 33%, and what leaves your cheque blends federal and provincial tax with CPP at 5.95% and EI at $1.63 per $100 of insurable earnings for 2026. Payroll also annualises each cheque, so a bonus or overtime period is taxed as if every period looked the same. Filing squares it up.
Taxable wages are the part of an employee's pay that income tax is calculated on: salary, hourly wages, overtime, bonuses, commissions, most allowances and the value of taxable benefits such as personal use of a company vehicle. They are not the same as gross pay, and they differ again from pensionable and insurable earnings, which drive CPP and EI. Box 14 of the T4 reports employment income for the calendar year.
