6 worked Permanent Establishment Tax Analysis 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 permanent establishment tax analysis work, not a specific client's file.
Case Study 1 · Deadline rescue
Filed On Time From A Standing Start, $71,000 Penalty Avoided — Cross-Border Contractor, Calgary
Client: A contractor working on both sides of the border · Where: Calgary, Alberta · Engagement: 4 weeks, fixed fee
Penalty avoided$71,000
Turnaround4 weeks
FiledOn time
The situation — A contractor working on both sides of the border, Calgary, Alberta
A contractor working on both sides of the border in Calgary, Alberta came to us 4 weeks before its filing deadline. The file came with winters spent in the United States with the day count kept casually and no residency position documented anywhere. A late filing would have triggered a penalty of roughly $71,000 before interest.
What we did for A contractor working on both sides of the border, Calgary, Alberta
We worked backwards from the deadline. We aligned the Canadian and US reporting of the same income so the foreign tax credit claim carried support on both returns. We prioritised the items that actually gated the filing and deferred everything that did not.
The result — A contractor working on both sides of the border, Calgary, Alberta
The return was filed on time and complete. The $71,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 2 · Records and systems rebuilt
Books Rebuilt From Source, $7,300 In Unclaimed Input Tax Found — Arizona Snowbird, London
Client: A snowbird spending winters in Arizona · Where: London, Ontario · Engagement: 3 weeks, fixed fee
Unclaimed tax found$7,300
Records rebuilt28 months
ProcessDocumented
The situation — A snowbird spending winters in Arizona, London, Ontario
A snowbird spending winters in Arizona in London, 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, London, 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, London, Ontario
Records rebuilt and reconciled, $7,300 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Case Study 3 · Objection and relief
Desk-Review Assessment Of $139,000 Vacated — US LLC Shareholder, Kelowna
Client: A shareholder of a US LLC · Where: Kelowna, British Columbia · Engagement: 7 weeks, fixed fee
Assessment vacated$139,000
Supporting recordsNow on file
AccountCleared
The situation — A shareholder of a US LLC, Kelowna, British Columbia
A shareholder of a US LLC in Kelowna, British Columbia was carrying $139,000 of penalties and interest. The charges arose from invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken. Much of that amount accumulated during a period the CRA itself had delayed.
What we did for A shareholder of a US LLC, Kelowna, British Columbia
We restructured the US holding so the Canadian and US characterisations aligned, ending the double taxation going forward. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
The result — A shareholder of a US LLC, Kelowna, British Columbia
The assessment was vacated. $139,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 4 · Planning that cut the bill
$59,000 Saved By Correcting What Prior Filings Had Missed — US Citizen in Canada, Hamilton
Client: A US citizen living in Canada · Where: Hamilton, Ontario · Engagement: 3 weeks, fixed fee
Saving identified$59,000
RecurringYes
Positions documentedAll
The situation — A US citizen living in Canada, Hamilton, Ontario
A US citizen living in Canada in Hamilton, Ontario asked for a second opinion on permanent establishment tax analysis. That followed three years of rising tax. The review found foreign accounts that had passed the $100,000 T1135 threshold three years earlier.
What we did for A US citizen living in Canada, Hamilton, Ontario
We built the comparison first: current structure against two alternatives. Then we reconstructed the day count on both sides of the border and documented the residency and treaty position before either revenue authority asked.
The result — A US citizen living in Canada, Hamilton, Ontario
First-year saving of $59,000, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 5 · Scaling without breaking
Scaled To 25 Staff With $111,000 Of Working Capital Freed — Canadian on US Payroll, Victoria
Client: A Canadian with a US employer · Where: Victoria, British Columbia · Engagement: 10 weeks, fixed fee
Headcount reached25
Working capital freed$111,000
Missed deadlinesZero
The situation — A Canadian with a US employer, Victoria, British Columbia
A Canadian with a US employer in Victoria, British Columbia was growing fast, with headcount reaching 25 in eighteen months. The back office had not kept up. A departure year filed as a normal resident return with no deemed disposition reported was the first thing to break.
What we did for A Canadian with a US employer, Victoria, British Columbia
We reported the deemed disposition properly on the departure return and claimed the foreign tax credits that had been left unused. We built the compliance calendar for the size the business was becoming rather than the size it had been.
The result — A Canadian with a US employer, Victoria, British Columbia
The business reached 25 staff with no missed remittance and no late filing. $111,000 of working capital was freed in the process.
Case Study 6 · Cash and remittance control
Instalments Rebased, $140,000 Of Cash Returned To The Business — US Pension Recipient, Mississauga
Client: A Canadian resident receiving US pension income · Where: Mississauga, Ontario · Engagement: 5 weeks, fixed fee
Cash returned$140,000
Instalment basisCurrent year
ReviewedQuarterly
The situation — A Canadian resident receiving US pension income, Mississauga, Ontario
A Canadian resident receiving US pension income in Mississauga, Ontario was paying instalments calculated on a prior year. That year no longer reflected the business. Dividends paid to a non-resident shareholder with nothing withheld, leaving the payer holding the liability was tying up $140,000 of cash.
What we did for A Canadian resident receiving US pension income, Mississauga, Ontario
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, 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, Mississauga, Ontario
$140,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
