6 worked GST/HST Quick Method Review case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to gst/hst quick method review work, not a specific client's file.
Case Study 1 · Deadline rescue
Filed On Time From A Standing Start, $22,500 Penalty Avoided — Used-Equipment Dealer, Mississauga
The situation — A used-equipment dealer, Mississauga, Ontario
A used-equipment dealer in Mississauga, Ontario came to us 7 weeks before its filing deadline. The file came with a registration threshold crossed nine months before anyone registered. A late filing would have triggered a penalty of roughly $22,500 before interest.
What we did for A used-equipment dealer, Mississauga, Ontario
We worked backwards from the deadline. 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. We prioritised the items that actually gated the filing and deferred everything that did not.
The result — A used-equipment dealer, Mississauga, Ontario
The return was filed on time and complete. The $22,500 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 2 · Objection and relief
$59,000 Of Penalties And Interest Cancelled On Relief — Digital Platform Seller, Winnipeg

Penalties and interest cancelled$59,000
Relief groundsAccepted
AssessmentAdjusted to filed position
The situation — A platform seller collecting tax at checkout, Winnipeg, Manitoba
An assessment of $59,000 landed at a platform seller collecting tax at checkout in Winnipeg, Manitoba following a desk review. It turned on management fees between two related registrants carrying tax that only ever went out and came back. The auditor had not seen the records behind it.
What we did for A platform seller collecting tax at checkout, Winnipeg, Manitoba
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 then set out the legislative basis for the position alongside the documents supporting it.
The result — A platform seller collecting tax at checkout, Winnipeg, Manitoba
$59,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.

Annual saving$66,000
ReorganisationTax-neutral
StructureMatches operations
The situation — A freight brokerage, Halifax, Nova Scotia
The structure at a freight brokerage in Halifax, Nova Scotia needed fixing. The file was carrying input tax credits claimed on the exempt side of a mixed-supply business. Every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did for A freight brokerage, Halifax, Nova Scotia
We worked with the client's lawyer. Together, we self-assessed the tax on the real property acquisition in the correct reporting period and claimed the offsetting input tax credit in the same return. We also prepared the elections, resolutions and valuations the structure needed to stand up.
The result — A freight brokerage, Halifax, Nova Scotia
The structure now matches the business. Annual saving of $66,000, and the reorganisation itself was tax-neutral.
Case Study 4 · Backlog brought current
Collections Halted And $128,000 Cut From A 4-Year Backlog — Interprovincial Construction Supplier, Burnaby

Balance reduced by$128,000
Backlog cleared4 years
CollectionsHalted
The situation — A construction supplier selling into three provinces, Burnaby, British Columbia
By the time a construction supplier selling into three provinces in Burnaby, British Columbia called, 4 years were outstanding. The CRA had assessed on estimates. Underneath it sat a commercial property purchase closed on the assumption no tax applied because the vendor was not registered.
What we did for A construction supplier selling into three provinces, Burnaby, British Columbia
We reconstructed the records year by year. We assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment. Each filing replaced an arbitrary assessment with a real one.
The result — A construction supplier selling into three provinces, Burnaby, British Columbia
The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $128,000, and a relief application addressed part of the accumulated interest.
Case Study 5 · Sale and succession
$305,000 Sheltered By The Lifetime Capital Gains Exemption — Mixed-Supply Practice, Kitchener
Client: A professional practice with exempt and taxable supplies · Where: Kitchener, Ontario · Engagement: 11 weeks, fixed fee
Gain sheltered$305,000
ClosingOn schedule
Share qualificationMet
The situation — A professional practice with exempt and taxable supplies, Kitchener, Ontario
A professional practice with exempt and taxable supplies in Kitchener, Ontario had an offer on the table and 17 months to close. The shares did not qualify for the capital gains exemption. A single shareholder holding every share, with no room to multiply the exemption was part of the reason.
What we did for A professional practice with exempt and taxable supplies, Kitchener, Ontario
We purified the corporation so the shares met the qualifying tests. We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. All of it was done well ahead of the closing date.
The result — A professional practice with exempt and taxable supplies, Kitchener, Ontario
The sale closed on schedule with $305,000 sheltered by the lifetime capital gains exemption across the shareholders.
Case Study 6 · Missed incentive claimed
$46,000 In Credits Claimed That Prior Filings Had Missed — Wholesale Food Distributor, Windsor
The situation — A wholesale food distributor, Windsor, Ontario
A wholesale food distributor in Windsor, Ontario had been filing for 3 years. In that time, the incentives its activity qualified for were never claimed. Behind that sat input tax credits claimed on the exempt side of a mixed-supply business.
What we did for A wholesale food distributor, Windsor, Ontario
We tested each activity against the eligibility criteria rather than the description on the invoice. 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.
The result — A wholesale food distributor, Windsor, Ontario
$46,000 in credits claimed, with the open prior years adjusted as well. The claim passed review without adjustment.
