Input tax credits can generally be claimed up to four years back for smaller registrants, but the documentation the CRA demands scales with invoice size. Our gst/hst return filing engagement is priced as a pocket-friendly flat fee, so the cost is known before the work starts.
Clients often arrive treating gst/hst return filing as a form-filling exercise. In practice, a tax preparation specialist spends more time on judgment calls than on data entry — and those calls are what these notes cover.
The foundation is simple to state and easy to trip over: Registration becomes mandatory once taxable supplies exceed $30,000 in a single calendar quarter or over four consecutive quarters. Exceeding it in one quarter makes the sale that crossed it taxable. Over four quarters, you stop being a small supplier at the end of the month after the fourth quarter.
The next point is the one a tax preparation specialist checks before quoting any timeline: 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. One more rule deserves attention, mostly because ignoring it is expensive in ways that only show up 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.
The practical upshot is simple: every one of these rules has a version that helps you and a version that costs you, and which one applies depends on choices made before filing. That is precisely the ground a tax preparation specialist covers. Gather whatever records touch the numbers — statements, ledgers, prior-year filings — and we take it from there.

Collections had begun against a seller who crossed the registration threshold before registering in Halifax, Nova Scotia over 6 years of unfiled returns. Bringing them current cut $19,500 from the balance.
By the time a seller who crossed the registration threshold before registering in Halifax, Nova Scotia called, 6 years were outstanding. The CRA had assessed on estimates. Underneath it sat nil periods left unfiled, which held up the refund on the one period that mattered. We reconstructed the records year by year. 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. 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 $19,500, and a relief application addressed part of the accumulated interest.
12 months of records at a residential landlord also renting commercial space in Lethbridge, Alberta had never been reconciled. That left input tax credits claimed on the exempt side of a mixed-supply business. Rebuilding recovered $11,500.
Nothing reconciled at a residential landlord also renting commercial space in Lethbridge, Alberta. Every filing started with 12 months of cleanup. The file was carrying input tax credits claimed on the exempt side of a mixed-supply business. We rebuilt from source rather than correcting on top of the existing file. 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. Then we set the routine that keeps it clean. 12 months reconciled to the bank. The close now takes 6 days, and $11,500 of previously unclaimable input tax was recovered in the process.
A professional practice with exempt and taxable supplies in Brampton, Ontario was under review. The issue was management fees between two related registrants carrying tax that only ever went out and came back. The file closed in 3 weeks with $57,000 of proposed tax cleared.
A professional practice with exempt and taxable supplies in Brampton, Ontario was selected for review. Management fees between two related registrants carrying tax that only ever went out and came back had shown up in the CRA's automated matching. The proposed adjustment on GST/HST return filing came to $57,000. 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. Every figure in the response traced to a source record the auditor could verify without asking a second question. The review closed with no change. $57,000 of proposed tax came off the table, and the documentation now in place makes the next review a short one.
A manufacturer exporting to the US in Mississauga, Ontario needed a holding structure. It had to deal with HST charged at the home-province rate on sales into four different provinces. The reorganisation was tax-neutral and removed $27,000 of annual exposure.
The structure at a manufacturer exporting to the US in Mississauga, Ontario needed fixing. The file was carrying HST charged at the home-province rate on sales into four different provinces. 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 brought the nil and missing periods current so the account was clean before the refund claim was filed. We also prepared the elections, resolutions and valuations the structure needed to stand up. The structure now matches the business. Annual saving of $27,000, and the reorganisation itself was tax-neutral.
Remittances at a freight brokerage in Victoria, British Columbia were chronically late. It came down to export sales zero-rated with no shipping documentation behind them. Fixing the schedule refunded $105,000.
Remittances at a freight brokerage in Victoria, British Columbia were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat export sales zero-rated with no shipping documentation behind them. We assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment. Then we moved the remittance dates into a scheduled process rather than a monthly decision. Penalties stopped from the following remittance onwards, and $105,000 of overpaid instalments was refunded.
A restaurant group in Hamilton, Ontario had never tested its work against the eligibility rules. The resulting $60,000 claim was accepted without adjustment.
A restaurant group in Hamilton, Ontario assumed the credits did not apply to a business its size. A commercial property purchase closed on the assumption no tax applied because the vendor was not registered meant they had applied all along. We identified the qualifying activity and built the documentation to support it. Then 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. $60,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
GST/HST Return Filing 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.

The short answer comes straight from our working notes: 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. How that plays out on your file depends on the specifics, which is exactly what the engagement is for.
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 is the part most owners have not heard before they sit down with us, and it usually changes what they do next.

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.
The GST rate is 5%, unchanged since 1 January 2008 and current for 2025 and 2026. It reaches every province and territory, but in five provinces it is folded into the HST: you charge 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia, down from 15% on 1 April 2025. In Alberta, the Northwest Territories, Nunavut and Yukon, 5% applies alone.
GST or HST is calculated on the selling price of a taxable supply and shown separately on the invoice. Place-of-supply rules decide which province's rate applies, and that is usually where the customer receives the goods or service rather than where you operate. A registrant remits the tax collected less input tax credits for GST or HST paid on business purchases, so the amount sent to the CRA with each return is the net figure, not everything collected.
The HST is a single sales tax blending the federal 5% GST with a participating province's own sales tax, collected and administered by the CRA. For 2026 it is 13% in Ontario, 14% in Nova Scotia since 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. A registrant charges HST on taxable supplies, claims input tax credits on its purchases, and remits the difference on one return. Elsewhere you charge the 5% GST plus any separate provincial tax.
Multiply the pre-tax price by the rate that applies where the sale happens. In Ontario that is 13% HST for 2026; in Alberta 5% GST; in British Columbia 5% GST plus 7% PST, each applied to the same base. Quebec is the exception, where 9.975% QST is charged on the pre-GST price, giving 14.975% combined. To back the tax out of a tax-included price, divide by one plus the rate.
HST stands for harmonized sales tax: the federal 5% GST blended with a participating province's sales tax into one rate the CRA administers. For 2026 that is 13% in Ontario, 14% in Nova Scotia since 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. Provinces that did not harmonise keep a separate provincial tax on top of the 5% GST, and Alberta, Yukon, the Northwest Territories and Nunavut charge 5% only.
Divide the tax-included total by one plus the tax rate. In Ontario, divide by 1.13 to get the pre-tax amount; the difference is the 13% HST. Use 1.05 for GST-only provinces, 1.14 in Nova Scotia since 1 April 2025, and 1.15 in New Brunswick, Newfoundland and Labrador and Prince Edward Island. Quebec is different: QST of 9.975% applies to the pre-GST price, so divide by 1.14975 for the combined amount.
Non-taxable means an amount is left out of income, so it does not add to your tax bill and generally does not reduce income-tested benefits. Examples include TFSA withdrawals, gifts and inheritances, lottery winnings and life insurance death benefits. Some amounts are non-taxable yet still have to be reported or tracked, such as a principal residence sale. When you are unsure, treat a receipt as taxable until a specific rule exempts it, and check the CRA's guidance.
A flat monthly car allowance is generally taxable, added to employment income on the T4 with source deductions taken. A per-kilometre reimbursement is different: if it is based on business kilometres actually driven at a reasonable rate, it is not taxable. For 2026 the CRA treats 73 cents per kilometre for the first 5,000 kilometres and 67 cents after as reasonable, with 4 cents more in the territories; the 2025 rates were 72 and 66 cents.
Sign in to CRA My Account, where past returns, notices of assessment and copies of the slips the CRA received, such as T4, T4A and T5, are available for several years back. Tax software approved for NETFILE can pull the same slips in through Auto-fill my return. If you cannot get online, phone the CRA or send a written request. Keep your own copies for six years from the end of the tax year they relate to.
A genuine CRA call can show as blocked, private or an unfamiliar number, so the display proves nothing either way. Judge the call by its content. The CRA will not demand payment by gift card, cryptocurrency or e-transfer, will not threaten immediate arrest or deportation, and will not ask for a passport or banking password. Hang up, then call an enquiry line published on canada.ca or check My Account for a real balance.
