6 worked Unfiled Corporate Tax Returns 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 unfiled corporate tax returns work, not a specific client's file.
Case Study 1 · Scaling without breaking
Scaled To 57 Staff With $86,000 Of Working Capital Freed — Incorporated Consultancy, Mississauga
The situation — An incorporated consultancy, Mississauga, Ontario
An incorporated consultancy in Mississauga, Ontario was growing fast, with headcount reaching 57 in eighteen months. The back office had not kept up. Passive investment income that had crossed the $50,000 grind threshold unnoticed was the first thing to break.
What we did for An incorporated consultancy, Mississauga, Ontario
We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down. We built the compliance calendar for the size the business was becoming rather than the size it had been.
The result — An incorporated consultancy, Mississauga, Ontario
The business reached 57 staff with no missed remittance and no late filing. $86,000 of working capital was freed in the process.

The situation — A corporation paying instalments on prior-year figures, Moncton, New Brunswick
A corporation paying instalments on prior-year figures in Moncton, New Brunswick had not filed for 5 years. The CRA had issued arbitrary assessments. The business was carrying a loss year carried forward by default when carrying it back would have produced a refund cheque. That came on top of a growing interest balance.
What we did for A corporation paying instalments on prior-year figures, Moncton, New Brunswick
We started with the oldest year and worked forward so each year's closing balances fed the next. 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 filed the years in sequence rather than all at once.
The result — A corporation paying instalments on prior-year figures, Moncton, New Brunswick
Every year is now filed and assessed on actual figures. The notional assessments were vacated and $69,000 of the estimated balance came off, with a payment arrangement covering the rest.
Case Study 3 · Records and systems rebuilt
Books Rebuilt From Source, $3,500 In Unclaimed Input Tax Found — Corporate Rental Portfolio, London
The situation — A corporately-owned rental portfolio, London, Ontario
A corporately-owned rental portfolio in London, Ontario could not answer basic questions about its own numbers. A balance-due date the owner believed was the same as the filing date sat between the bank statements and the ledger.
What we did for A corporately-owned rental portfolio, London, Ontario
We reconstructed the capital dividend account from the underlying transactions and filed the subsection 83(2) election before the next distribution left the company. We then documented the process so the work does not depend on any one person remembering how it was done.
The result — A corporately-owned rental portfolio, London, Ontario
Records rebuilt and reconciled, $3,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.

Review duration7 weeks
OutcomeNo change
The situation — A corporation with a non-calendar fiscal year-end, Edmonton, Alberta
A corporation with a non-calendar fiscal year-end in Edmonton, Alberta was selected for review. A distribution treated as tax-free capital dividend with no election ever filed had shown up in the CRA's automated matching. The proposed adjustment on unfiled corporate tax returns came to $28,000.
What we did for A corporation with a non-calendar fiscal year-end, Edmonton, Alberta
We modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year. Every figure in the response traced to a source record the auditor could verify without asking a second question.
The result — A corporation with a non-calendar fiscal year-end, Edmonton, Alberta
The review closed with no change. $28,000 of proposed tax came off the table, and the documentation now in place makes the next review a short one.

Annual saving$35,500
ReorganisationTax-neutral
StructureMatches operations
The situation — A technology CCPC approaching its first profitable year, Barrie, Ontario
The structure at a technology CCPC approaching its first profitable year in Barrie, Ontario needed fixing. The file was carrying two corporations under common control filing as if each had its own $500,000 limit. Every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did for A technology CCPC approaching its first profitable year, Barrie, Ontario
We worked with the client's lawyer. Together, we rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual. We also prepared the elections, resolutions and valuations the structure needed to stand up.
The result — A technology CCPC approaching its first profitable year, Barrie, Ontario
The structure now matches the business. Annual saving of $35,500, and the reorganisation itself was tax-neutral.
Case Study 6 · Cash and remittance control
$36,500 Of Working Capital Freed From The Tax Cycle — Two-Shareholder CCPC, Burnaby
Client: A CCPC with two shareholders · Where: Burnaby, British Columbia · Engagement: 10 weeks, fixed fee
Working capital freed$36,500
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A CCPC with two shareholders, Burnaby, British Columbia
A CCPC with two shareholders in Burnaby, British Columbia was profitable on paper and short of cash every month. Dividends moved up to a holding company year after year with no safe-income support on file explained most of the gap.
What we did for A CCPC with two shareholders, Burnaby, British Columbia
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 — A CCPC with two shareholders, Burnaby, British Columbia
$36,500 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
