Canadian Corporation with a US Subsidiary Case Studies

6 worked Canadian Corporation with a US Subsidiary 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 canadian corporation with a us subsidiary work, not a specific client's file.

Case Study 1 · Backlog brought current

5 Years Filed, $121,000 Removed From The Assessed Balance — Florida Property Owner, Toronto

Client: A family with a Florida vacation property  ·  Where: Toronto, Ontario  ·  Engagement: 5 weeks, fixed fee

Years filed5
Assessed balance removed$121,000
CollectionsStopped

The situation — A family with a Florida vacation property, Toronto, Ontario

A family with a Florida vacation property in Toronto, Ontario had not filed for 5 years. The CRA had issued arbitrary assessments. The business was carrying dividends paid to a non-resident shareholder with nothing withheld, leaving the payer holding the liability. That came on top of a growing interest balance.

What we did for A family with a Florida vacation property, Toronto, Ontario

We started with the oldest year and worked forward so each year's closing balances fed the next. We reconstructed the day count on both sides of the border and documented the residency and treaty position before either revenue authority asked. We filed the years in sequence rather than all at once.

The result — A family with a Florida vacation property, Toronto, Ontario

Every year is now filed and assessed on actual figures. The notional assessments were vacated and $121,000 of the estimated balance came off, with a payment arrangement covering the rest.

Case Study 2 · Records and systems rebuilt

Books Rebuilt From Source, $6,800 In Unclaimed Input Tax Found — Arizona Snowbird, Barrie

Client: A snowbird spending winters in Arizona  ·  Where: Barrie, Ontario  ·  Engagement: 3 weeks, fixed fee

Unclaimed tax found$6,800
Records rebuilt19 months
ProcessDocumented

The situation — A snowbird spending winters in Arizona, Barrie, Ontario

A snowbird spending winters in Arizona in Barrie, Ontario could not answer basic questions about its own numbers. 25% withholding on gross Canadian rent where a section 216 election would have taxed only the net sat between the bank statements and the ledger.

What we did for A snowbird spending winters in Arizona, Barrie, Ontario

We registered the payer for a non-resident withholding account, remitted the Regulation 105 amounts due, and applied for waivers covering the rest of the contract. We then documented the process so the work does not depend on any one person remembering how it was done.

The result — A snowbird spending winters in Arizona, Barrie, Ontario

Records rebuilt and reconciled, $6,800 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.

Case Study 3 · Cash and remittance control

Remittance Schedule Corrected, $117,000 Refunded — Inbound Assignee, Red Deer

Client: An inbound transferee on assignment  ·  Where: Red Deer, Alberta  ·  Engagement: 3 weeks, fixed fee

Overpayment refunded$117,000
Late remittances sinceZero
ScheduleAutomated

The situation — An inbound transferee on assignment, Red Deer, Alberta

Remittances at an inbound transferee on assignment in Red Deer, Alberta were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat winters spent in the United States with the day count kept casually and no residency position documented anywhere.

What we did for An inbound transferee on assignment, Red Deer, Alberta

We filed the section 216 election with the supporting rental statements and recovered the excess withholding as a refund. Then we moved the remittance dates into a scheduled process rather than a monthly decision.

The result — An inbound transferee on assignment, Red Deer, Alberta

Penalties stopped from the following remittance onwards, and $117,000 of overpaid instalments was refunded.

Case Study 4 · Missed incentive claimed

$132,000 Credit Claim Filed And Accepted Without Adjustment — US Pension Recipient, Burnaby

Client: A Canadian resident receiving US pension income  ·  Where: Burnaby, British Columbia  ·  Engagement: 6 weeks, fixed fee

Claim value$132,000
AcceptedWithout adjustment
RepeatableAnnually

The situation — A Canadian resident receiving US pension income, Burnaby, British Columbia

A Canadian resident receiving US pension income in Burnaby, British Columbia assumed the credits did not apply to a business its size. Invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken meant they had applied all along.

What we did for A Canadian resident receiving US pension income, Burnaby, British Columbia

We identified the qualifying activity and built the documentation to support it. Then we filed the outstanding T1135 disclosures through the Voluntary Disclosures Program, which eliminated the penalty exposure entirely.

The result — A Canadian resident receiving US pension income, Burnaby, British Columbia

$132,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.

Case Study 5 · Sale and succession

Intergenerational Transfer Completed With $870,000 Deferred — Non-Resident Landlord, Surrey

Client: A non-resident owning Canadian rental property  ·  Where: Surrey, British Columbia  ·  Engagement: 3 weeks, fixed fee

Tax deferred$870,000
TransferCompleted
RecordsReview-ready

The situation — A non-resident owning Canadian rental property, Surrey, British Columbia

A generational transfer at a non-resident owning Canadian rental property in Surrey, British Columbia had been discussed for years without a plan. Passive assets sitting inside the operating company, disqualifying the shares meant the transfer as contemplated would have been fully taxable.

What we did for A non-resident owning Canadian rental property, Surrey, British Columbia

We aligned the Canadian and US reporting of the same income so the foreign tax credit claim carried support on both returns. We sequenced the steps so each one was complete and documented before the next depended on it.

The result — A non-resident owning Canadian rental property, Surrey, British Columbia

$870,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.

Case Study 6 · Deadline rescue

Filed On Time From A Standing Start, $104,000 Penalty Avoided — US LLC Shareholder, Edmonton

Client: A shareholder of a US LLC  ·  Where: Edmonton, Alberta  ·  Engagement: 11 weeks, fixed fee

Penalty avoided$104,000
Turnaround11 weeks
FiledOn time

The situation — A shareholder of a US LLC, Edmonton, Alberta

A shareholder of a US LLC in Edmonton, Alberta came to us 11 weeks before its filing deadline. The file came with US tax paid but no foreign tax credit claimed on the Canadian return. A late filing would have triggered a penalty of roughly $104,000 before interest.

What we did for A shareholder of a US LLC, Edmonton, Alberta

We worked backwards from the deadline. We applied the treaty rate to the dividend withholding, filed the NR4 return, and remitted the shortfall before the CRA assessed the payer for it. We prioritised the items that actually gated the filing and deferred everything that did not.

The result — A shareholder of a US LLC, Edmonton, Alberta

The return was filed on time and complete. The $104,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
