6 worked GST/HST Return Correction 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 return correction work, not a specific client's file.
Case Study 1 · Sale and succession
Intergenerational Transfer Completed With $605,000 Deferred — Interprovincial Marketing Agency, Windsor
Client: A marketing agency billing outside its home province · Where: Windsor, Ontario · Engagement: 6 weeks, fixed fee
Tax deferred$605,000
TransferCompleted
RecordsReview-ready
The situation — A marketing agency billing outside its home province, Windsor, Ontario
A generational transfer at a marketing agency billing outside its home province in Windsor, Ontario 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.
What we did for A marketing agency billing outside its home province, Windsor, Ontario
We rebuilt the sales ledger by customer province, applied the correct place-of-supply rate to each stream, and filed corrected returns before the CRA opened a review, sequencing the steps so each one was complete and documented before the next depended on it.
The result — A marketing agency billing outside its home province, Windsor, Ontario
$605,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
Case Study 2 · Planning that cut the bill
Remuneration Review Saved $49,000 Across Corporate And Personal Returns — Used-Equipment Dealer, Surrey
Client: A used-equipment dealer · Where: Surrey, British Columbia · Engagement: 3 weeks, fixed fee
Combined saving$49,000
ScopeCorporate + personal
Future yearsNo rework needed
The situation — A used-equipment dealer, Surrey, British Columbia
Nothing was wrong at a used-equipment dealer in Surrey, British Columbia — the filings were on time and accurate. What they were not was planned. Export sales zero-rated with no shipping documentation behind them had never been reviewed.
What we did for A used-equipment dealer, Surrey, British Columbia
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, and ran the numbers across both the corporate and personal returns so the saving was real rather than deferred into someone else's hands.
The result — A used-equipment dealer, Surrey, British Columbia
$49,000 came off the combined corporate and personal tax bill, and the structure holds for future years without further work.
Case Study 3 · Objection and relief
$41,000 Of Penalties And Interest Cancelled On Relief — Restaurant Group, Guelph
Client: A restaurant group · Where: Guelph, Ontario · Engagement: 8 weeks, fixed fee
Penalties and interest cancelled$41,000
Relief groundsAccepted
AssessmentAdjusted to filed position
The situation — A restaurant group, Guelph, Ontario
An assessment of $41,000 landed at a restaurant group in Guelph, Ontario following a desk review. The auditor had not seen the records behind a commercial property purchase closed on the assumption no tax applied because the vendor was not registered.
What we did for A restaurant group, Guelph, Ontario
We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings, then set out the legislative basis for the position alongside the documents supporting it.
The result — A restaurant group, Guelph, Ontario
$41,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.
Case Study 4 · Missed incentive claimed
$123,000 Credit Claim Filed And Accepted Without Adjustment — Freight Brokerage, Burnaby
Client: A freight brokerage · Where: Burnaby, British Columbia · Engagement: 9 weeks, fixed fee
Claim value$123,000
AcceptedWithout adjustment
RepeatableAnnually
The situation — A freight brokerage, Burnaby, British Columbia
A freight brokerage in Burnaby, British Columbia assumed the credits did not apply to a business its size. A registration threshold crossed nine months before anyone registered meant they had applied all along.
What we did for A freight brokerage, Burnaby, British Columbia
We identified the qualifying activity, built the documentation to support it, and 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.
The result — A freight brokerage, Burnaby, British Columbia
$123,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
Case Study 5 · Cash and remittance control
Remittance Schedule Corrected, $22,000 Refunded — US-Bound Exporter, Vancouver
Client: A manufacturer exporting to the US · Where: Vancouver, British Columbia · Engagement: 9 weeks, fixed fee
Overpayment refunded$22,000
Late remittances sinceZero
ScheduleAutomated
The situation — A manufacturer exporting to the US, Vancouver, British Columbia
Remittances at a manufacturer exporting to the US in Vancouver, British Columbia were consistently late by a few days, which was enough to trigger penalties every quarter. Behind it sat a sales tax account filed annually while the CRA had moved the business to quarterly.
What we did for A manufacturer exporting to the US, Vancouver, British Columbia
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 moved the remittance dates into a scheduled process rather than a monthly decision.
The result — A manufacturer exporting to the US, Vancouver, British Columbia
Penalties stopped from the following remittance onwards, and $22,000 of overpaid instalments was refunded.
Client: A professional practice with exempt and taxable supplies · Where: Red Deer, Alberta · Engagement: 10 weeks, fixed fee
Annual saving$61,000
ReorganisationTax-neutral
StructureMatches operations
The situation — A professional practice with exempt and taxable supplies, Red Deer, Alberta
A professional practice with exempt and taxable supplies in Red Deer, Alberta was carrying nil periods left unfiled, which held up the refund on the one period that mattered, and every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did for A professional practice with exempt and taxable supplies, Red Deer, Alberta
Working with the client's lawyer, we backdated the registration to the day the threshold was crossed, remitted the tax owing, and applied for relief on the penalty portion and prepared the elections, resolutions and valuations the structure needed to stand up.
The result — A professional practice with exempt and taxable supplies, Red Deer, Alberta
The structure now matches the business. Annual saving of $61,000, and the reorganisation itself was tax-neutral.
