Multi-Province Corporate Tax Filing Case Studies

6 worked Multi-Province Corporate Tax Filing 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 multi-province corporate tax filing work, not a specific client's file.

Case Study 1 · CRA review defended

Audit Defence Closed In 9 Weeks, $132,000 Cleared — Three-Location Franchisee, Saskatoon

Client: A franchise operator with three locations  ·  Where: Saskatoon, Saskatchewan  ·  Engagement: 9 weeks, fixed fee

Proposed tax cleared$132,000
Review duration9 weeks
OutcomeNo change

The situation — A franchise operator with three locations, Saskatoon, Saskatchewan

A franchise operator with three locations in Saskatoon, Saskatchewan was selected for review. A small business limit quietly shared across three associated corporations nobody had mapped had shown up in the CRA's automated matching. The proposed adjustment on multi-province corporate tax filing came to $132,000.

What we did for A franchise operator with three locations, 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. Every figure in the response traced to a source record the auditor could verify without asking a second question.

The result — A franchise operator with three locations, Saskatoon, Saskatchewan

The review closed with no change. $132,000 of proposed tax came off the table, and the documentation now in place makes the next review a short one.

Case Study 2 · Deadline rescue

$75,000 Late-Filing Penalty Cancelled On Relief Application — Holding and Operating Companies, Lethbridge

Client: A holding company and its operating subsidiary  ·  Where: Lethbridge, Alberta  ·  Engagement: 6 weeks, fixed fee

Penalty cancelled$75,000
Relief applicationGranted
ReturnAccepted as filed

The situation — A holding company and its operating subsidiary, Lethbridge, Alberta

A holding company and its operating subsidiary in Lethbridge, Alberta had already missed one deadline and was about to miss a second. Behind it sat two corporations under common control filing as if each had its own $500,000 limit. A penalty of $75,000 was accruing.

What we did for A holding company and its operating subsidiary, Lethbridge, Alberta

We split the work into what had to happen before the deadline and what could follow it. Then we reconstructed the capital dividend account from the underlying transactions and filed the subsection 83(2) election before the next distribution left the company.

The result — A holding company and its operating subsidiary, Lethbridge, Alberta

The outstanding return was accepted as filed, and the taxpayer relief application cancelled $75,000 of the penalty already assessed on the earlier year.

Case Study 3 · Missed incentive claimed

Incentive Review Recovered $96,000 Across 4 Open Years — Instalment-Paying Corporation, Burnaby

Client: A corporation paying instalments on prior-year figures  ·  Where: Burnaby, British Columbia  ·  Engagement: 3 weeks, fixed fee

Recovered$96,000
Open years claimed4
Ongoing trackingIn place

The situation — A corporation paying instalments on prior-year figures, Burnaby, British Columbia

An incentive review at a corporation paying instalments on prior-year figures in Burnaby, British Columbia started from a simple question: what has never been claimed? The answer ran to 4 years. It was driven by a balance-due date the owner believed was the same as the filing date.

What we did for A corporation paying instalments on prior-year figures, Burnaby, British Columbia

We rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.

The result — A corporation paying instalments on prior-year figures, Burnaby, British Columbia

The credits produced $96,000 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.

Case Study 4 · Records and systems rebuilt

Books Rebuilt From Source, $10,500 In Unclaimed Input Tax Found — Import and Distribution Corporation, Calgary

Client: An import and distribution corporation  ·  Where: Calgary, Alberta  ·  Engagement: 9 weeks, fixed fee

Unclaimed tax found$10,500
Records rebuilt9 months
ProcessDocumented

The situation — An import and distribution corporation, Calgary, Alberta

An import and distribution corporation 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 An import and distribution corporation, 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 documented the process so the work does not depend on any one person remembering how it was done.

The result — An import and distribution corporation, Calgary, Alberta

Records rebuilt and reconciled, $10,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.

Case Study 5 · Sale and succession

$620,000 Sheltered By The Lifetime Capital Gains Exemption — Corporate Rental Portfolio, Regina

Client: A corporately-owned rental portfolio  ·  Where: Regina, Saskatchewan  ·  Engagement: 8 weeks, fixed fee

Gain sheltered$620,000
ClosingOn schedule
Share qualificationMet

The situation — A corporately-owned rental portfolio, Regina, Saskatchewan

A corporately-owned rental portfolio in Regina, Saskatchewan had an offer on the table and 26 months to close. The shares did not qualify for the capital gains exemption. A shareholder loan balance that would have been picked up as income on closing was part of the reason.

What we did for A corporately-owned rental portfolio, Regina, Saskatchewan

We purified the corporation so the shares met the qualifying tests. We carried the non-capital loss back against the two profitable years and recovered tax already paid instead of holding a carry-forward balance. All of it was done well ahead of the closing date.

The result — A corporately-owned rental portfolio, Regina, Saskatchewan

The sale closed on schedule with $620,000 sheltered by the lifetime capital gains exemption across the shareholders.

Case Study 6 · Cash and remittance control

$117,000 Of Working Capital Freed From The Tax Cycle — Second-Generation Manufacturer, Mississauga

Client: A second-generation family manufacturer  ·  Where: Mississauga, Ontario  ·  Engagement: 9 weeks, fixed fee

Working capital freed$117,000
On-time remittancesEvery period since
Forecast horizon13 weeks

The situation — A second-generation family manufacturer, Mississauga, Ontario

A second-generation family manufacturer in Mississauga, Ontario 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 second-generation family manufacturer, Mississauga, Ontario

We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.

The result — A second-generation family manufacturer, Mississauga, Ontario

$117,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
