GST Returns Case Studies

6 GST Returns 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 returns work, not a general example.

Case Study 1 · Deadline rescue

Filed On Time From A Standing Start, $17,000 Penalty Avoided — Professional Corporation, Regina

Client: A professional corporation  ·  Where: Regina, Saskatchewan  ·  Engagement: 8 weeks, fixed fee

Penalty avoided$17,000
Turnaround8 weeks
FiledOn time

The situation

A professional corporation in Regina, Saskatchewan came to us 8 weeks before its filing deadline with two corporations under common control filing as if each had its own $500,000 limit. A late filing would have triggered a penalty of roughly $17,000 before interest.

What we did

We worked backwards from the deadline. We mapped the association rules across the group, allocated the business limit deliberately on Schedule 23, and corrected the prior year by adjustment request, prioritising the items that actually gated the filing and deferring everything that did not.

The result

The return was filed on time and complete. The $17,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.

Case Study 2 · Missed incentive claimed

Incentive Review Recovered $46,000 Across 3 Open Years — Incorporated Trades Business, Barrie

Client: An incorporated trades business  ·  Where: Barrie, Ontario  ·  Engagement: 5 weeks, fixed fee

Recovered$46,000
Open years claimed3
Ongoing trackingIn place

The situation

An incentive review at an incorporated trades business in Barrie, Ontario started from a simple question: what has never been claimed? The answer ran to 3 years, driven by two corporations under common control filing as if each had its own $500,000 limit.

What we did

We modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year, documenting eligibility to the standard a reviewer would apply rather than the standard a claim form requires.

The result

The credits produced $46,000 across the open years, and the tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.

Case Study 3 · Records and systems rebuilt

Books Rebuilt From Source, $7,000 In Unclaimed Input Tax Found — Franchise Operator with Three, Vancouver

Client: A franchise operator with three locations  ·  Where: Vancouver, British Columbia  ·  Engagement: 3 weeks, fixed fee

Unclaimed tax found$7,000
Records rebuilt32 months
ProcessDocumented

The situation

A franchise operator with three locations in Vancouver, British Columbia could not answer basic questions about its own numbers, because a small business limit quietly shared across three associated corporations nobody had mapped sat between the bank statements and the ledger.

What we did

We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual, then documented the process so the work does not depend on any one person remembering how it was done.

The result

Records rebuilt and reconciled, $7,000 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.

Case Study 4 · Sale and succession

Intergenerational Transfer Completed With $775,000 Deferred — CCPC with Two Shareholders, Surrey

Client: A CCPC with two shareholders  ·  Where: Surrey, British Columbia  ·  Engagement: 9 weeks, fixed fee

Tax deferred$775,000
TransferCompleted
RecordsReview-ready

The situation

A generational transfer at a CCPC with two shareholders in Surrey, British Columbia had been discussed for years without a plan. A single shareholder holding every share, with no room to multiply the exemption meant the transfer as contemplated would have been fully taxable.

What we did

We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down, sequencing the steps so each one was complete and documented before the next depended on it.

The result

$775,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.

Case Study 5 · Cash and remittance control

Instalments Rebased, $108,000 Of Cash Returned To The Business — Corporately-Owned Rental Portfolio, Kitchener

Client: A corporately-owned rental portfolio  ·  Where: Kitchener, Ontario  ·  Engagement: 10 weeks, fixed fee

Cash returned$108,000
Instalment basisCurrent year
ReviewedQuarterly

The situation

A corporately-owned rental portfolio in Kitchener, Ontario was paying instalments calculated on a prior year that no longer reflected the business. A balance-due date the owner believed was the same as the filing date was tying up $108,000 of cash.

What we did

We rebased the instalments on the current-year estimate rather than the prior-year default, and mapped the association rules across the group, allocated the business limit deliberately on Schedule 23, and corrected the prior year by adjustment request.

The result

$108,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.

Case Study 6 · Backlog brought current

Collections Halted And $98,000 Cut From A 4-Year Backlog — Second-Generation Family Manufacturer, Kelowna

Client: A second-generation family manufacturer  ·  Where: Kelowna, British Columbia  ·  Engagement: 6 weeks, fixed fee

Balance reduced by$98,000
Backlog cleared4 years
CollectionsHalted

The situation

By the time a second-generation family manufacturer in Kelowna, British Columbia called, 4 years were outstanding and the CRA had assessed on estimates. Underneath it sat two corporations under common control filing as if each had its own $500,000 limit.

What we did

We reconstructed the records year by year and modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year. Each filing replaced an arbitrary assessment with a real one.

The result

The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $98,000, and a relief application addressed part of the accumulated interest.
