NR6 Undertaking to File a Section 216 Return Case Studies
6 worked NR6 Undertaking to File a Section 216 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 nr6 undertaking to file a section 216 return work, not a specific client's file.
Case Study 1 · CRA review defended
$41,000 Proposed Adjustment Withdrawn In Full — Newly Resident Student, London
Client: An international student newly resident · Where: London, Ontario · Engagement: 10 weeks, fixed fee
Adjustment withdrawn$41,000
File closed in10 weeks
Penalties assessedNone
The situation — An international student newly resident, London, Ontario
An international student newly resident in London, Ontario received a proposal letter opening a review of NR6 undertaking to file a section 216 return. The CRA had identified withholding taken on gross Canadian rent for three years with no section 216 return ever filed. It proposed an adjustment of $41,000, with 30 days to respond.
What we did for An international student newly resident, London, Ontario
We treated the response as an evidence exercise rather than an argument. 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. We then indexed every supporting document against the specific line the auditor had questioned.
The result — An international student newly resident, London, Ontario
The proposed adjustment was withdrawn in full — all $41,000 of it. The file closed in 10 weeks with no change to the assessed amounts and no penalty.
Case Study 2 · Cash and remittance control
$149,000 Of Working Capital Freed From The Tax Cycle — Non-Resident Pensioner, Calgary
Client: A non-resident pension recipient · Where: Calgary, Alberta · Engagement: 6 weeks, fixed fee
Working capital freed$149,000
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A non-resident pension recipient, Calgary, Alberta
A non-resident pension recipient in Calgary, Alberta was profitable on paper and short of cash every month. A treaty tie-breaker position asserted on the return with no analysis behind it explained most of the gap.
What we did for A non-resident pension recipient, Calgary, Alberta
We put an NR6 undertaking in place with the Canadian agent so the following year was withheld on estimated net rent rather than on gross. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A non-resident pension recipient, Calgary, Alberta
$149,000 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 3 · Objection and relief
Notice Of Objection Allowed In Full, $65,000 Reversed — Departing Emigrant, Kitchener
Client: An emigrant severing Canadian ties · Where: Kitchener, Ontario · Engagement: 7 weeks, fixed fee
Amount reversed$65,000
ObjectionAllowed in full
Account balanceNil
The situation — An emigrant severing Canadian ties, Kitchener, Ontario
An emigrant severing Canadian ties in Kitchener, Ontario had been reassessed for $65,000. 11 days were left on the objection deadline. The reassessment rested on a T1135 filed for the year of arrival, when none was required, and none filed for the years that followed.
What we did for An emigrant severing Canadian ties, Kitchener, Ontario
We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, 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.
The result — An emigrant severing Canadian ties, Kitchener, Ontario
The appeals officer allowed the objection in full. $65,000 was reversed and the account returned to a nil balance.
Case Study 4 · Sale and succession
$790,000 Sheltered By The Lifetime Capital Gains Exemption — Non-Resident Shareholder, Ottawa
The situation — A non-resident shareholder drawing dividends, Ottawa, Ontario
A non-resident shareholder drawing dividends in Ottawa, Ontario had an offer on the table and 20 months to close. The shares did not qualify for the capital gains exemption. A shareholder loan balance that would have been picked up as income on closing was part of the reason.
What we did for A non-resident shareholder drawing dividends, Ottawa, Ontario
We purified the corporation so the shares met the qualifying tests. We filed the section 217 election after running the calculation both ways. The Canadian pension and benefit income was then taxed under the ordinary rate structure rather than at the flat withholding rate. All of it was done well ahead of the closing date.
The result — A non-resident shareholder drawing dividends, Ottawa, Ontario
The sale closed on schedule with $790,000 sheltered by the lifetime capital gains exemption across the shareholders.
Client: A non-resident property vendor · Where: Moncton, New Brunswick · Engagement: 5 weeks, fixed fee
Amount recovered$15,000
Reporting statusCurrent
Annual effortHours, not weeks
The situation — A non-resident property vendor, Moncton, New Brunswick
Foreign holdings at a non-resident property vendor in Moncton, New Brunswick had passed the reporting threshold without anyone noticing. Behind the disclosure problem sat a non-resident disposition of Canadian property completed with no clearance certificate on file and a quarter of the price still held back.
What we did for A non-resident property vendor, Moncton, New Brunswick
We worked the treaty tie-breaker in order: permanent home, then centre of vital interests, then habitual abode. We put the supporting facts in the file rather than asserting the conclusion on the return. We claimed the treaty relief and foreign tax credits on the Canadian return and corrected the disclosure position for the open years.
The result — A non-resident property vendor, Moncton, New Brunswick
The treaty position was accepted and $15,000 was recovered. Reporting is now current and the annual process takes hours rather than weeks.
Case Study 6 · Scaling without breaking
Second-Province Expansion Handled, $140,000 Of Cash Released — Returning Former Resident, Halifax
Client: A returning former resident · Where: Halifax, Nova Scotia · Engagement: 5 weeks, fixed fee
Cash released$140,000
New registrationsComplete on day one
Compliance gapsNone
The situation — A returning former resident, Halifax, Nova Scotia
Revenue at a returning former resident in Halifax, Nova Scotia was up sharply and cash was tighter than ever. Underneath it sat rent remitted abroad in full by a Canadian agent who had never been told the withholding was their obligation.
What we did for A returning former resident, Halifax, Nova Scotia
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. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing.
The result — A returning former resident, Halifax, Nova Scotia
$140,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
