Professional Corporation Tax Planning Case Studies

6 worked Professional Corporation Tax Planning 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 professional corporation tax planning work, not a specific client's file.

Case Study 1 · Sale and succession

Intergenerational Transfer Completed With $885,000 Deferred — Instalment-Paying Corporation, Vancouver

Client: A corporation paying instalments on prior-year figures  ·  Where: Vancouver, British Columbia  ·  Engagement: 9 weeks, fixed fee

Tax deferred$885,000
TransferCompleted
RecordsReview-ready

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

A generational transfer at a corporation paying instalments on prior-year figures in Vancouver, British Columbia had been discussed for years without a plan. No valuation on file to support the price the parties had agreed meant the transfer as contemplated would have been fully taxable.

What we did for A corporation paying instalments on prior-year figures, Vancouver, 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 sequenced the steps so each one was complete and documented before the next depended on it.

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

$885,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.

Case Study 2 · Structure rebuilt

Holding Structure Added, $31,000 Saved Annually — Corporate Rental Portfolio, Saskatoon

Client: A corporately-owned rental portfolio  ·  Where: Saskatoon, Saskatchewan  ·  Engagement: 7 weeks, fixed fee

Annual saving$31,000
ReorganisationTax-neutral
StructureMatches operations

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

The structure at a corporately-owned rental portfolio in Saskatoon, Saskatchewan needed fixing. The file was carrying retained earnings building in the operating company with no plan for extracting them. Every option for fixing it ran through a reorganisation that had to be done without triggering tax.

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

We worked with the client's lawyer. Together, we documented safe income before the inter-corporate dividend was paid, so subsection 55(2) had no room to recharacterise it as a gain. We also prepared the elections, resolutions and valuations the structure needed to stand up.

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

The structure now matches the business. Annual saving of $31,000, and the reorganisation itself was tax-neutral.

Case Study 3 · Deadline rescue

Filed On Time From A Standing Start, $74,000 Penalty Avoided — Two-Shareholder CCPC, Windsor

Client: A CCPC with two shareholders  ·  Where: Windsor, Ontario  ·  Engagement: 11 weeks, fixed fee

Penalty avoided$74,000
Turnaround11 weeks
FiledOn time

The situation — A CCPC with two shareholders, Windsor, Ontario

A CCPC with two shareholders in Windsor, Ontario came to us 11 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 $74,000 before interest.

What we did for A CCPC with two shareholders, Windsor, Ontario

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 CCPC with two shareholders, Windsor, Ontario

The return was filed on time and complete. The $74,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.

Case Study 4 · Cash and remittance control

Instalments Rebased, $101,000 Of Cash Returned To The Business — Incorporated Trades Business, Mississauga

Client: An incorporated trades business  ·  Where: Mississauga, Ontario  ·  Engagement: 11 weeks, fixed fee

Cash returned$101,000
Instalment basisCurrent year
ReviewedQuarterly

The situation — An incorporated trades business, Mississauga, Ontario

An incorporated trades business in Mississauga, Ontario was paying instalments calculated on a prior year. That year no longer reflected the business. A loss year carried forward by default when carrying it back would have produced a refund cheque was tying up $101,000 of cash.

What we did for An incorporated trades business, Mississauga, Ontario

We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, we rebuilt the instalment schedule off the current year rather than the prior year, ending the interest accrual.

The result — An incorporated trades business, Mississauga, Ontario

$101,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.

Case Study 5 · Scaling without breaking

Second-Province Expansion Handled, $70,000 Of Cash Released — Professional Corporation, London

Client: A professional corporation  ·  Where: London, Ontario  ·  Engagement: 11 weeks, fixed fee

Cash released$70,000
New registrationsComplete on day one
Compliance gapsNone

The situation — A professional corporation, London, Ontario

Revenue at a professional corporation in London, Ontario was up sharply and cash was tighter than ever. Underneath it sat a balance-due date the owner believed was the same as the filing date.

What we did for A professional corporation, London, Ontario

We moved passive holdings into a separate structure so the operating company’s small business limit stopped grinding down. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing.

The result — A professional corporation, London, Ontario

$70,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.

Case Study 6 · Missed incentive claimed

$105,000 Credit Claim Filed And Accepted Without Adjustment — Associated Corporation Pair, Moncton

Client: A corporation associated with a spouse-owned company  ·  Where: Moncton, New Brunswick  ·  Engagement: 9 weeks, fixed fee

Claim value$105,000
AcceptedWithout adjustment
RepeatableAnnually

The situation — A corporation associated with a spouse-owned company, Moncton, New Brunswick

A corporation associated with a spouse-owned company in Moncton, New Brunswick assumed the credits did not apply to a business its size. Passive investment income that had crossed the $50,000 grind threshold unnoticed meant they had applied all along.

What we did for A corporation associated with a spouse-owned company, Moncton, New Brunswick

We identified the qualifying activity and built the documentation to support it. Then 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.

The result — A corporation associated with a spouse-owned company, Moncton, New Brunswick

$105,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
