6 GST/HST Return Adjustment tax and accounting engagements in full — what the client came to us with, what we did, and what it was worth. Each one is specific to gst/hst return adjustment work, not a general example.
Case Study 1 · Objection and relief
Notice Of Objection Allowed In Full, $129,000 Reversed — Corporation Under a GST/HST, Brampton
Client: A corporation under a GST/HST review · Where: Brampton, Ontario · Engagement: 10 weeks, fixed fee
Amount reversed$129,000
ObjectionAllowed in full
Account balanceNil
The situation
A corporation under a GST/HST review in Brampton, Ontario had been reassessed for $129,000 and had 7 days left on the objection deadline. The reassessment rested on an objection deadline that had passed with no extension applied for.
What we did
We filed the objection inside the deadline with a complete submission rather than a placeholder, and filed the disclosure through the Voluntary Disclosures Program before contact, which removed the gross-negligence penalty entirely.
The result
The appeals officer allowed the objection in full. $129,000 was reversed and the account returned to a nil balance.
Case Study 2 · Backlog brought current
$92,000 Of Arbitrary Assessments Vacated After 3 Years — Family Business Under a, Lethbridge
Client: A family business under a related-party review · Where: Lethbridge, Alberta · Engagement: 9 weeks, fixed fee
Arbitrary tax vacated$92,000
Years brought current3
Account statusCurrent
The situation
3 years of unfiled returns had turned into notional assessments at a family business under a related-party review in Lethbridge, Alberta, with a director liability assessment for a corporation that had already stopped operating underneath. Collections had already started.
What we did
We brought every outstanding return current, then negotiated a payment arrangement that stopped the collections action, then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.
The result
All 3 years were accepted as filed. $92,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 3 years.
Case Study 3 · Missed incentive claimed
$30,000 Credit Claim Filed And Accepted Without Adjustment — Business Owner with a, Halifax
Client: A business owner with a director liability assessment · Where: Halifax, Nova Scotia · Engagement: 7 weeks, fixed fee
Claim value$30,000
AcceptedWithout adjustment
RepeatableAnnually
The situation
A business owner with a director liability assessment in Halifax, Nova Scotia assumed the credits did not apply to a business its size. Six years of unfiled corporate and personal returns and an active collections file meant they had applied all along.
What we did
We identified the qualifying activity, built the documentation to support it, and assembled the contemporaneous records, filed a structured response to each proposed adjustment with the supporting documents indexed, and had the proposal withdrawn.
The result
$30,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
Case Study 4 · Scaling without breaking
Second-Province Expansion Handled, $110,000 Of Cash Released — Importer Under a Customs, Moncton
Client: An importer under a customs and GST audit · Where: Moncton, New Brunswick · Engagement: 9 weeks, fixed fee
Cash released$110,000
New registrationsComplete on day one
Compliance gapsNone
The situation
Revenue at an importer under a customs and GST audit in Moncton, New Brunswick was up sharply and cash was tighter than ever. Underneath it sat six years of unfiled corporate and personal returns and an active collections file.
What we did
We traced each unexplained deposit to its source — loans, transfers between accounts, an insurance settlement — and reduced the net-worth assessment accordingly. Every new obligation — registration, remittance frequency, provincial filing — was set up before it was triggered, not after.
The result
$110,000 of cash was released from the working capital cycle, and the expansion completed with every registration and filing obligation covered from day one.
Case Study 5 · Cash and remittance control
Instalments Rebased, $67,000 Of Cash Returned To The Business — Professional Under a Lifestyle, Ottawa
Client: A professional under a lifestyle audit · Where: Ottawa, Ontario · Engagement: 4 weeks, fixed fee
Cash returned$67,000
Instalment basisCurrent year
ReviewedQuarterly
The situation
A professional under a lifestyle audit in Ottawa, Ontario was paying instalments calculated on a prior year that no longer reflected the business. A proposal letter with a 30-day response window and no supporting records assembled was tying up $67,000 of cash.
What we did
We rebased the instalments on the current-year estimate rather than the prior-year default, and filed the disclosure through the Voluntary Disclosures Program before contact, which removed the gross-negligence penalty entirely.
The result
$67,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
Case Study 6 · Deadline rescue
6-Week Turnaround Beat The Deadline And Saved $20,000 — Restaurant Under a Net-Worth, Kitchener

Filed with21 days to spare
Next yearPapers ready
The situation
With the deadline for gst/hst return adjustment weeks away, a restaurant under a net-worth audit in Kitchener, Ontario was carrying an objection deadline that had passed with no extension applied for. The exposure if the date slipped was around $20,000.
What we did
We brought every outstanding return current, then negotiated a payment arrangement that stopped the collections action. The filing went in complete rather than provisional, so there was no amended return to follow.
The result
Filed with 21 days to spare. $20,000 in late-filing penalties avoided, and the working papers are ready for the following year.
