6 worked Corporate Tax Minimization 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 corporate tax minimization work, not a specific client's file.
Case Study 1 · Deadline rescue
Filed On Time From A Standing Start, $99,000 Penalty Avoided — Corporate Rental Portfolio, Winnipeg
The situation — A corporately-owned rental portfolio, Winnipeg, Manitoba
A corporately-owned rental portfolio in Winnipeg, Manitoba came to us 8 weeks before its filing deadline. The file came with retained earnings building in the operating company with no plan for extracting them. A late filing would have triggered a penalty of roughly $99,000 before interest.
What we did for A corporately-owned rental portfolio, Winnipeg, Manitoba
We worked backwards from the deadline. We carried the non-capital loss back against the two profitable years and recovered tax already paid instead of holding a carry-forward balance. We prioritised the items that actually gated the filing and deferred everything that did not.
The result — A corporately-owned rental portfolio, Winnipeg, Manitoba
The return was filed on time and complete. The $99,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 2 · Records and systems rebuilt
Books Rebuilt From Source, $20,500 In Unclaimed Input Tax Found — Second-Generation Manufacturer, Calgary
Client: A second-generation family manufacturer · Where: Calgary, Alberta · Engagement: 10 weeks, fixed fee
Unclaimed tax found$20,500
Records rebuilt15 months
ProcessDocumented
The situation — A second-generation family manufacturer, Calgary, Alberta
A second-generation family manufacturer in Calgary, Alberta could not answer basic questions about its own numbers. Passive investment income that had crossed the $50,000 grind threshold unnoticed sat between the bank statements and the ledger.
What we did for A second-generation family manufacturer, Calgary, Alberta
We modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year. We then documented the process so the work does not depend on any one person remembering how it was done.
The result — A second-generation family manufacturer, Calgary, Alberta
Records rebuilt and reconciled, $20,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Client: A CCPC with two shareholders · Where: Barrie, Ontario · Engagement: 5 weeks, fixed fee
Overpayment refunded$76,000
Late remittances sinceZero
ScheduleAutomated
The situation — A CCPC with two shareholders, Barrie, Ontario
Remittances at a CCPC with two shareholders in Barrie, Ontario were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat a distribution treated as tax-free capital dividend with no election ever filed.
What we did for A CCPC with two shareholders, Barrie, Ontario
We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual. Then we moved the remittance dates into a scheduled process rather than a monthly decision.
The result — A CCPC with two shareholders, Barrie, Ontario
Penalties stopped from the following remittance onwards, and $76,000 of overpaid instalments was refunded.
Case Study 4 · Planning that cut the bill
$34,500 Saved By Correcting What Prior Filings Had Missed — Corporation Holding Investments, Kitchener
Client: An operating company holding surplus investments · Where: Kitchener, Ontario · Engagement: 10 weeks, fixed fee
Saving identified$34,500
RecurringYes
Positions documentedAll
The situation — An operating company holding surplus investments, Kitchener, Ontario
An operating company holding surplus investments in Kitchener, Ontario asked for a second opinion on corporate tax minimization. That followed three years of rising tax. The review found two corporations under common control filing as if each had its own $500,000 limit.
What we did for An operating company holding surplus investments, Kitchener, Ontario
We built the comparison first: current structure against two alternatives. Then we moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down.
The result — An operating company holding surplus investments, Kitchener, Ontario
First-year saving of $34,500, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 5 · Scaling without breaking
Scaled To 79 Staff With $46,000 Of Working Capital Freed — Incorporated Trades Business, Saskatoon
Client: An incorporated trades business · Where: Saskatoon, Saskatchewan · Engagement: 11 weeks, fixed fee
Headcount reached79
Working capital freed$46,000
Missed deadlinesZero
The situation — An incorporated trades business, Saskatoon, Saskatchewan
An incorporated trades business in Saskatoon, Saskatchewan was growing fast, with headcount reaching 79 in eighteen months. The back office had not kept up. A small business limit quietly shared across three associated corporations nobody had mapped was the first thing to break.
What we did for An incorporated trades business, Saskatoon, Saskatchewan
We mapped the association rules across the group, allocated the business limit deliberately on Schedule 23, and corrected the prior year by adjustment request. We built the compliance calendar for the size the business was becoming rather than the size it had been.
The result — An incorporated trades business, Saskatoon, Saskatchewan
The business reached 79 staff with no missed remittance and no late filing. $46,000 of working capital was freed in the process.
Case Study 6 · CRA review defended
$25,500 Reassessment Reduced To Nil On Review — Incorporated Consultancy, Ottawa
The situation — An incorporated consultancy, Ottawa, Ontario
A review notice arrived at an incorporated consultancy in Ottawa, Ontario, covering corporate tax minimization for two tax years. The auditor's working position was an adjustment of $25,500. It was driven by a loss year carried forward by default when carrying it back would have produced a refund cheque.
What we did for An incorporated consultancy, Ottawa, Ontario
Rather than negotiate, we rebuilt the record. We reviewed each capital cost allowance pool and set the claim at the level that kept the small business deduction fully used rather than wasted. We then submitted a point-by-point response that answered each proposed adjustment with the document behind it.
The result — An incorporated consultancy, Ottawa, Ontario
The auditor accepted the documented position and closed the review without adjustment, protecting $25,500 and leaving the prior filings undisturbed.
