Tax Residency and Treaty Tie-Breaker Review Case Studies
6 worked Tax Residency and Treaty Tie-Breaker Review 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 tax residency and treaty tie-breaker review work, not a specific client's file.
Case Study 1 · Deadline rescue
11-Week Turnaround Beat The Deadline And Saved $44,000 — Newly Resident Student, Calgary
Client: An international student newly resident · Where: Calgary, Alberta · Engagement: 11 weeks, fixed fee
Late-filing penalty avoided$44,000
Filed with8 days to spare
Next yearPapers ready
The situation — An international student newly resident, Calgary, Alberta
An international student newly resident in Calgary, Alberta was weeks away from the deadline for tax residency and treaty tie-breaker review. Behind that sat personal credits claimed in full for a year of part-year residency, as though the taxpayer had been resident from January. The exposure if the date slipped was around $44,000.
What we did for An international student newly resident, Calgary, Alberta
We filed the notification of disposition and obtained the clearance certificate. We released the proceeds the purchaser had been holding against a withholding calculated on the gross price. The filing went in complete rather than provisional, so there was no amended return to follow.
The result — An international student newly resident, Calgary, Alberta
Filed with 8 days to spare. $44,000 in late-filing penalties avoided, and the working papers are ready for the following year.
Case Study 2 · Planning that cut the bill

The situation — A returning former resident, Edmonton, Alberta
A returning former resident in Edmonton, Alberta asked for a second opinion on tax residency and treaty tie-breaker review. That followed three years of rising tax. The review found more than half the year spent in Canada on visits while the returns continued to be filed as a non-resident.
What we did for A returning former resident, Edmonton, Alberta
We built the comparison first: current structure against two alternatives. Then we split the year at the residency date and prorated the personal credits to the days of residency. We refiled the years that had claimed the full amounts.
The result — A returning former resident, Edmonton, Alberta
First-year saving of $45,000, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 3 · Missed incentive claimed
Incentive Review Recovered $30,500 Across 7 Open Years — Non-Resident Shareholder, Hamilton
The situation — A non-resident shareholder drawing dividends, Hamilton, Ontario
An incentive review at a non-resident shareholder drawing dividends in Hamilton, Ontario started from a simple question: what has never been claimed? The answer ran to 7 years. It was driven by withholding taken on gross Canadian rent for three years with no section 216 return ever filed.
What we did for A non-resident shareholder drawing dividends, Hamilton, Ontario
We documented the fair market value of each property as at the date residency began. That way the deemed acquisition cost was on file long before a sale put it in issue. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result — A non-resident shareholder drawing dividends, Hamilton, Ontario
The credits produced $30,500 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
Case Study 4 · Structure rebuilt
Corporate Structure Rebuilt For $51,000 Of Annual Savings — Non-Resident Pensioner, Saskatoon
The situation — A non-resident pension recipient, Saskatoon, Saskatchewan
The structure at a non-resident pension recipient in Saskatoon, Saskatchewan dated from years earlier. It had been set up for a business that no longer existed. A non-resident disposition of Canadian property completed with no clearance certificate on file and a quarter of the price still held back had become expensive.
What we did for A non-resident pension recipient, Saskatoon, Saskatchewan
We filed the section 216 returns for the open years, so the rent was taxed on a net basis after allowable expenses. We recovered the excess withholding as a refund. The reorganisation used the rollover provisions rather than a taxable transfer, so no tax fell due on the restructuring itself.
The result — A non-resident pension recipient, Saskatoon, Saskatchewan
$51,000 of annual saving, achieved on a tax-deferred basis. The minute book, elections and valuations are all in the file.
Case Study 5 · Records and systems rebuilt
9 Months Reconciled And $7,500 Of Input Tax Recovered — Non-Resident Director, Brampton
Client: A non-resident director of a Canadian corporation · Where: Brampton, Ontario · Engagement: 11 weeks, fixed fee
Months reconciled9
Input tax recovered$7,500
Close time6 days
The situation — A non-resident director of a Canadian corporation, Brampton, Ontario
Nothing reconciled at a non-resident director of a Canadian corporation in Brampton, Ontario. Every filing started with 9 months of cleanup. The file was carrying an arrival year reported from January rather than from the date residency actually began.
What we did for A non-resident director of a Canadian corporation, Brampton, Ontario
We rebuilt from source rather than correcting on top of the existing file. We applied for the withholding waiver before the next payment cycle. We set up the T4A-NR reporting so the withholding stopped exceeding the tax that was actually owed. Then we set the routine that keeps it clean.
The result — A non-resident director of a Canadian corporation, Brampton, Ontario
9 months reconciled to the bank. The close now takes 6 days, and $7,500 of previously unclaimable input tax was recovered in the process.
Case Study 6 · Scaling without breaking
Growth Handled Without A Missed Filing, $137,000 Freed — Non-Resident Vendor, Red Deer
Client: A non-resident property vendor · Where: Red Deer, Alberta · Engagement: 7 weeks, fixed fee
Cash freed$137,000
Compliance failuresNone
ReportingMonthly
The situation — A non-resident property vendor, Red Deer, Alberta
A non-resident property vendor in Red Deer, Alberta was opening in a second province. That meant different filing obligations and a different payroll regime. A house in Canada still available for occupation and a spouse still resident, while the returns were filed as a non-resident already sat in the file.
What we did for A non-resident property vendor, Red Deer, Alberta
We corrected the foreign property reporting from the first year it was actually required, using the voluntary route before the CRA raised it. We then put monthly reporting in place. That let the owner see the cash effect of growth while there was still time to act on it.
The result — A non-resident property vendor, Red Deer, Alberta
Growth was absorbed without a compliance failure. $137,000 of cash was released, and the monthly reporting now flags a problem while it is still small.
