6 worked Canadian Expat Tax Return 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 expat tax return work, not a specific client's file.
Case Study 1 · Deadline rescue
$88,000 Late-Filing Penalty Cancelled On Relief Application — Canadian on US Payroll, Brampton
Client: A Canadian with a US employer · Where: Brampton, Ontario · Engagement: 9 weeks, fixed fee
Penalty cancelled$88,000
Relief applicationGranted
ReturnAccepted as filed
The situation — A Canadian with a US employer, Brampton, Ontario
A Canadian with a US employer in Brampton, Ontario had already missed one deadline and was about to miss a second. Behind it sat a departure year filed as a normal resident return with no deemed disposition reported, and a penalty of $88,000 was accruing.
What we did for A Canadian with a US employer, Brampton, Ontario
We split the work into what had to happen before the deadline and what could follow it, then reported the deemed disposition properly on the departure return and claimed the foreign tax credits that had been left unused.
The result — A Canadian with a US employer, Brampton, Ontario
The outstanding return was accepted as filed, and the taxpayer relief application cancelled $88,000 of the penalty already assessed on the earlier year.
Case Study 2 · Backlog brought current

Client: A Canadian resident receiving US pension income · Where: Surrey, British Columbia · Engagement: 8 weeks, fixed fee
Arbitrary tax vacated$73,000
Years brought current7
Account statusCurrent
The situation — A Canadian resident receiving US pension income, Surrey, British Columbia
7 years of unfiled returns had turned into notional assessments at a Canadian resident receiving US pension income in Surrey, British Columbia, with a US LLC taxed as a corporation in Canada, producing double tax on the same income underneath. Collections had already started.
What we did for A Canadian resident receiving US pension income, Surrey, British Columbia
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, then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.
The result — A Canadian resident receiving US pension income, Surrey, British Columbia
All 7 years were accepted as filed. $73,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 7 years.
Case Study 3 · CRA review defended

Client: A dual citizen with a US retirement account · Where: Mississauga, Ontario · Engagement: 6 weeks, fixed fee
Reassessment reduced toNil
Tax protected$113,000
Prior filingsUndisturbed
The situation — A dual citizen with a US retirement account, Mississauga, Ontario
A review notice arrived at a dual citizen with a US retirement account in Mississauga, Ontario covering canadian expat tax return for two tax years. The auditor's working position was an adjustment of $113,000, driven by winters spent in the United States with the day count kept casually and no residency position documented anywhere.
What we did for A dual citizen with a US retirement account, Mississauga, Ontario
Rather than negotiate, we rebuilt the record. 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 and submitted a point-by-point response that answered each proposed adjustment with the document behind it.
The result — A dual citizen with a US retirement account, Mississauga, Ontario
The auditor accepted the documented position and closed the review without adjustment, protecting $113,000 and leaving the prior filings undisturbed.
Case Study 4 · Cash and remittance control

ReviewedQuarterly
The situation — A contractor working on both sides of the border, Guelph, Ontario
A contractor working on both sides of the border in Guelph, Ontario was paying instalments calculated on a prior year that no longer reflected the business. Invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken was tying up $110,000 of cash.
What we did for A contractor working on both sides of the border, Guelph, Ontario
We rebased the instalments on the current-year estimate rather than the prior-year default, and 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 contractor working on both sides of the border, Guelph, Ontario
$110,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.

Relief groundsAccepted
AssessmentAdjusted to filed position
The situation — A snowbird spending winters in Arizona, Victoria, British Columbia
An assessment of $14,000 landed at a snowbird spending winters in Arizona in Victoria, British Columbia following a desk review. The auditor had not seen the records behind US tax paid but no foreign tax credit claimed on the Canadian return.
What we did for A snowbird spending winters in Arizona, Victoria, British Columbia
We aligned the Canadian and US reporting of the same income so the foreign tax credit claim carried support on both returns, then set out the legislative basis for the position alongside the documents supporting it.
The result — A snowbird spending winters in Arizona, Victoria, British Columbia
$14,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.

RecordsReview-ready
The situation — A shareholder of a US LLC, Burnaby, British Columbia
A generational transfer at a shareholder of a US LLC in Burnaby, British Columbia had been discussed for years without a plan. A shareholder loan balance that would have been picked up as income on closing meant the transfer as contemplated would have been fully taxable.
What we did for A shareholder of a US LLC, Burnaby, British Columbia
We filed the outstanding T1135 disclosures through the Voluntary Disclosures Program, which eliminated the penalty exposure entirely, sequencing the steps so each one was complete and documented before the next depended on it.

$500,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
