6 worked US Form 1040 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 us form 1040 filing work, not a specific client's file.
Case Study 1 · Deadline rescue
$59,000 Late-Filing Penalty Cancelled On Relief Application — US Retirement Account Holder, Calgary
Client: A dual citizen with a US retirement account · Where: Calgary, Alberta · Engagement: 9 weeks, fixed fee
Penalty cancelled$59,000
Relief applicationGranted
ReturnAccepted as filed
The situation — A dual citizen with a US retirement account, Calgary, Alberta
A dual citizen with a US retirement account in Calgary, Alberta had already missed one deadline and was about to miss a second. Behind it sat winters spent in the United States with the day count kept casually and no residency position documented anywhere, and a penalty of $59,000 was accruing.
What we did for A dual citizen with a US retirement account, Calgary, Alberta
We split the work into what had to happen before the deadline and what could follow it, then aligned the Canadian and US reporting of the same income so the foreign tax credit claim carried support on both returns.
The result — A dual citizen with a US retirement account, Calgary, Alberta
The outstanding return was accepted as filed, and the taxpayer relief application cancelled $59,000 of the penalty already assessed on the earlier year.
Case Study 2 · Objection and relief
Desk-Review Assessment Of $17,500 Vacated — US Rental Owner, Toronto
Client: A Canadian resident with a US rental property · Where: Toronto, Ontario · Engagement: 9 weeks, fixed fee
Assessment vacated$17,500
Supporting recordsNow on file
AccountCleared
The situation — A Canadian resident with a US rental property, Toronto, Ontario
A Canadian resident with a US rental property in Toronto, Ontario was carrying $17,500 of penalties and interest arising from a departure year filed as a normal resident return with no deemed disposition reported, much of it accumulated during a period the CRA itself had delayed.
What we did for A Canadian resident with a US rental property, Toronto, Ontario
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 framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
The result — A Canadian resident with a US rental property, Toronto, Ontario
The assessment was vacated. $17,500 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 3 · Records and systems rebuilt
Books Rebuilt From Source, $19,000 In Unclaimed Input Tax Found — US LLC Shareholder, Lethbridge
Client: A shareholder of a US LLC · Where: Lethbridge, Alberta · Engagement: 10 weeks, fixed fee
Unclaimed tax found$19,000
Records rebuilt27 months
ProcessDocumented
The situation — A shareholder of a US LLC, Lethbridge, Alberta
A shareholder of a US LLC in Lethbridge, Alberta could not answer basic questions about its own numbers, because foreign accounts that had passed the $100,000 T1135 threshold three years earlier sat between the bank statements and the ledger.
What we did for A shareholder of a US LLC, Lethbridge, Alberta
We reported the deemed disposition properly on the departure return and claimed the foreign tax credits that had been left unused, then documented the process so the work does not depend on any one person remembering how it was done.
The result — A shareholder of a US LLC, Lethbridge, Alberta
Records rebuilt and reconciled, $19,000 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Case Study 4 · Planning that cut the bill
$46,000 Cut From The Annual Tax Bill — Non-Resident Landlord, Guelph
Client: A non-resident owning Canadian rental property · Where: Guelph, Ontario · Engagement: 8 weeks, fixed fee
First-year saving$46,000
RepeatsAnnually
Filing positionUnchanged in risk
The situation — A non-resident owning Canadian rental property, Guelph, Ontario
A non-resident owning Canadian rental property in Guelph, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly and still left US tax paid but no foreign tax credit claimed on the Canadian return on the table.
What we did for A non-resident owning Canadian rental property, Guelph, Ontario
We modelled the current position against the alternatives before changing anything, then restructured the US holding so the Canadian and US characterisations aligned, ending the double taxation going forward.
The result — A non-resident owning Canadian rental property, Guelph, Ontario
The change saved $46,000 in the first year and repeats annually. Nothing about the filings became more aggressive; the position is simply the one the rules already allowed.
Case Study 5 · Cash and remittance control
$148,000 Of Working Capital Freed From The Tax Cycle — US Pension Recipient, Kelowna
Client: A Canadian resident receiving US pension income · Where: Kelowna, British Columbia · Engagement: 7 weeks, fixed fee
Working capital freed$148,000
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A Canadian resident receiving US pension income, Kelowna, British Columbia
A Canadian resident receiving US pension income in Kelowna, British Columbia was profitable on paper and short of cash every month. A US LLC taxed as a corporation in Canada, producing double tax on the same income explained most of the gap.
What we did for A Canadian resident receiving US pension income, Kelowna, British Columbia
We filed the outstanding T1135 disclosures through the Voluntary Disclosures Program, which eliminated the penalty exposure entirely and built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A Canadian resident receiving US pension income, Kelowna, British Columbia
$148,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
Case Study 6 · Scaling without breaking
Scaled To 62 Staff With $116,000 Of Working Capital Freed — Inbound Assignee, Barrie
Client: An inbound transferee on assignment · Where: Barrie, Ontario · Engagement: 11 weeks, fixed fee
Headcount reached62
Working capital freed$116,000
Missed deadlinesZero
The situation — An inbound transferee on assignment, Barrie, Ontario
An inbound transferee on assignment in Barrie, Ontario was growing fast — headcount to 62 in eighteen months — and the back office had not kept up. Invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken was the first thing to break.
What we did for An inbound transferee on assignment, Barrie, Ontario
We reconstructed the day count on both sides of the border and documented the residency and treaty position before either revenue authority asked, and built the compliance calendar for the size the business was becoming rather than the size it had been.
The result — An inbound transferee on assignment, Barrie, Ontario
The business reached 62 staff with no missed remittance and no late filing. $116,000 of working capital was freed in the process.
