6 worked Quebec Corporate Tax Return 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 quebec corporate tax return work, not a specific client's file.
Case Study 1 · Planning that cut the bill
$27,000 Saved By Correcting What Prior Filings Had Missed — Corporate Rental Portfolio, Winnipeg
The situation — A corporately-owned rental portfolio, Winnipeg, Manitoba
A corporately-owned rental portfolio in Winnipeg, Manitoba asked for a second opinion on Quebec corporate tax return. That followed three years of rising tax. The review found retained earnings building in the operating company with no plan for extracting them.
What we did for A corporately-owned rental portfolio, Winnipeg, Manitoba
We built the comparison first: current structure against two alternatives. Then we carried the non-capital loss back against the two profitable years and recovered tax already paid instead of holding a carry-forward balance.
The result — A corporately-owned rental portfolio, Winnipeg, Manitoba
First-year saving of $27,000, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 2 · Deadline rescue
Filed On Time From A Standing Start, $32,500 Penalty Avoided — Second-Generation Manufacturer, Toronto
Client: A second-generation family manufacturer · Where: Toronto, Ontario · Engagement: 10 weeks, fixed fee
Penalty avoided$32,500
Turnaround10 weeks
FiledOn time
The situation — A second-generation family manufacturer, Toronto, Ontario
A second-generation family manufacturer in Toronto, Ontario came to us 10 weeks before its filing deadline. The file came with passive investment income that had crossed the $50,000 grind threshold unnoticed. A late filing would have triggered a penalty of roughly $32,500 before interest.
What we did for A second-generation family manufacturer, Toronto, Ontario
We worked backwards from the deadline. We modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year. We prioritised the items that actually gated the filing and deferred everything that did not.
The result — A second-generation family manufacturer, Toronto, Ontario
The return was filed on time and complete. The $32,500 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 3 · Backlog brought current
$47,000 Of Arbitrary Assessments Vacated After 5 Years — Two-Shareholder CCPC, Windsor
Client: A CCPC with two shareholders · Where: Windsor, Ontario · Engagement: 6 weeks, fixed fee
Arbitrary tax vacated$47,000
Years brought current5
Account statusCurrent
The situation — A CCPC with two shareholders, Windsor, Ontario
5 years of unfiled returns had turned into notional assessments at a CCPC with two shareholders in Windsor, Ontario. Underneath lay a distribution treated as tax-free capital dividend with no election ever filed. Collections had already started.
What we did for A CCPC with two shareholders, Windsor, Ontario
We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual. We then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.
The result — A CCPC with two shareholders, Windsor, Ontario
All 5 years were accepted as filed. $47,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 5 years.
Case Study 4 · CRA review defended
$34,000 Proposed Adjustment Withdrawn In Full — Corporation Holding Investments, Burnaby
Client: An operating company holding surplus investments · Where: Burnaby, British Columbia · Engagement: 11 weeks, fixed fee
Adjustment withdrawn$34,000
File closed in11 weeks
Penalties assessedNone
The situation — An operating company holding surplus investments, Burnaby, British Columbia
An operating company holding surplus investments in Burnaby, British Columbia received a proposal letter opening a review of Quebec corporate tax return. The CRA had identified two corporations under common control filing as if each had its own $500,000 limit. It proposed an adjustment of $34,000, with 30 days to respond.
What we did for An operating company holding surplus investments, Burnaby, British Columbia
We treated the response as an evidence exercise rather than an argument. We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down. We then indexed every supporting document against the specific line the auditor had questioned.
The result — An operating company holding surplus investments, Burnaby, British Columbia
The proposed adjustment was withdrawn in full — all $34,000 of it. The file closed in 11 weeks with no change to the assessed amounts and no penalty.
Case Study 5 · Cash and remittance control
$19,500 Of Working Capital Freed From The Tax Cycle — Incorporated Trades Business, Hamilton
Client: An incorporated trades business · Where: Hamilton, Ontario · Engagement: 4 weeks, fixed fee
Working capital freed$19,500
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — An incorporated trades business, Hamilton, Ontario
An incorporated trades business in Hamilton, Ontario was profitable on paper and short of cash every month. A small business limit quietly shared across three associated corporations nobody had mapped explained most of the gap.
What we did for An incorporated trades business, Hamilton, Ontario
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 also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — An incorporated trades business, Hamilton, Ontario
$19,500 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
Case Study 6 · Objection and relief
$112,000 Of Penalties And Interest Cancelled On Relief — Incorporated Consultancy, Calgary
Client: An incorporated consultancy · Where: Calgary, Alberta · Engagement: 5 weeks, fixed fee
Penalties and interest cancelled$112,000
Relief groundsAccepted
AssessmentAdjusted to filed position
The situation — An incorporated consultancy, Calgary, Alberta
An assessment of $112,000 landed at an incorporated consultancy in Calgary, Alberta following a desk review. It turned on a loss year carried forward by default when carrying it back would have produced a refund cheque. The auditor had not seen the records behind it.
What we did for An incorporated consultancy, Calgary, Alberta
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 set out the legislative basis for the position alongside the documents supporting it.
The result — An incorporated consultancy, Calgary, Alberta
$112,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.
