6 Unfiled Corporate Tax 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 unfiled corporate tax returns work, not a general example.
Case Study 1 · Scaling without breaking
Scaled To 57 Staff With $86,000 Of Working Capital Freed — Incorporated Consultancy, Mississauga
An incorporated consultancy in Mississauga, Ontario was growing fast — headcount to 57 in eighteen months — and 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
We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down, and built the compliance calendar for the size the business was becoming rather than the size it had been.
The result
The business reached 57 staff with no missed remittance and no late filing. $86,000 of working capital was freed in the process.
Case Study 2 · Backlog brought current
5 Years Filed, $69,000 Removed From The Assessed Balance — Professional Corporation, Moncton
Client: A professional corporation · Where: Moncton, New Brunswick · Engagement: 11 weeks, fixed fee
Years filed5
Assessed balance removed$69,000
CollectionsStopped
The situation
A professional corporation in Moncton, New Brunswick had not filed for 5 years. The CRA had issued arbitrary assessments, and the business was carrying two corporations under common control filing as if each had its own $500,000 limit on top of a growing interest balance.
What we did
We started with the oldest year and worked forward so each year's closing balances fed the next. We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual, filing the years in sequence rather than all at once.
The result
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 — Import and Distribution Corporation, London
Client: An import and distribution corporation · Where: London, Ontario · Engagement: 4 weeks, fixed fee
Unclaimed tax found$3,500
Records rebuilt27 months
ProcessDocumented
The situation
An import and distribution corporation in London, Ontario 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 modelled salary against dividends across both the corporation and the shareholder’s personal return, then set the remuneration mix for the year, 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, $3,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Client: A corporately-owned rental portfolio · Where: Edmonton, Alberta · Engagement: 7 weeks, fixed fee
Proposed tax cleared$28,000
Review duration7 weeks
OutcomeNo change
The situation
A corporately-owned rental portfolio in Edmonton, Alberta was selected for review after a balance-due date the owner believed was the same as the filing date showed up in the CRA's automated matching. The proposed adjustment on unfiled corporate tax returns came to $28,000.
What we did
We mapped the association rules across the group, allocated the business limit deliberately on Schedule 23, and corrected the prior year by adjustment request. Every figure in the response traced to a source record the auditor could verify without asking a second question.
The result
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.
Client: A second-generation family manufacturer · Where: Barrie, Ontario · Engagement: 4 weeks, fixed fee
Annual saving$35,500
ReorganisationTax-neutral
StructureMatches operations
The situation
A second-generation family manufacturer in Barrie, Ontario was carrying retained earnings building in the operating company with no plan for extracting them, and every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did
Working with the client's lawyer, we moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down and prepared the elections, resolutions and valuations the structure needed to stand up.
The result
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 — CCPC with Two Shareholders, 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 in Burnaby, British Columbia was profitable on paper and short of cash every month. Passive investment income that had crossed the $50,000 grind threshold unnoticed explained most of the gap.
What we did
We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual and built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result
$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.
