6 worked NR4 Withholding 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 nr4 withholding tax return work, not a specific client's file.
Case Study 1 · Objection and relief
Desk-Review Assessment Of $82,000 Vacated — Non-Resident Pensioner, Halifax
Client: A non-resident pension recipient · Where: Halifax, Nova Scotia · Engagement: 4 weeks, fixed fee
Assessment vacated$82,000
Supporting recordsNow on file
AccountCleared
The situation — A non-resident pension recipient, Halifax, Nova Scotia
A non-resident pension recipient in Halifax, Nova Scotia was carrying $82,000 of penalties and interest. The charges arose from an arrival year reported from January rather than from the date residency actually began. Much of that amount accumulated during a period the CRA itself had delayed.
What we did for A non-resident pension recipient, 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. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
The result — A non-resident pension recipient, Halifax, Nova Scotia
The assessment was vacated. $82,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 2 · Scaling without breaking
Growth Handled Without A Missed Filing, $135,000 Freed — Non-Resident Vendor, Surrey
Client: A non-resident property vendor · Where: Surrey, British Columbia · Engagement: 10 weeks, fixed fee
Cash freed$135,000
Compliance failuresNone
ReportingMonthly
The situation — A non-resident property vendor, Surrey, British Columbia
A non-resident property vendor in Surrey, British Columbia was opening in a second province. That meant different filing obligations and a different payroll regime. Withholding taken on gross Canadian rent for three years with no section 216 return ever filed already sat in the file.
What we did for A non-resident property vendor, Surrey, British Columbia
We counted the days of presence in Canada year by year and established that the deemed residence rule had been triggered. We brought the world-income returns current for the affected years. 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, Surrey, British Columbia
Growth was absorbed without a compliance failure. $135,000 of cash was released, and the monthly reporting now flags a problem while it is still small.
Case Study 3 · Missed incentive claimed
Incentive Review Recovered $18,500 Across 3 Open Years — Newly Resident Student, Hamilton
Client: An international student newly resident · Where: Hamilton, Ontario · Engagement: 3 weeks, fixed fee
Recovered$18,500
Open years claimed3
Ongoing trackingIn place
The situation — An international student newly resident, Hamilton, Ontario
An incentive review at an international student newly resident in Hamilton, Ontario started from a simple question: what has never been claimed? The answer ran to 3 years. It was driven by a house in Canada still available for occupation and a spouse still resident, while the returns were filed as a non-resident.
What we did for An international student newly resident, Hamilton, Ontario
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 documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result — An international student newly resident, Hamilton, Ontario
The credits produced $18,500 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 · Backlog brought current
7 Years Filed, $13,500 Removed From The Assessed Balance — Non-Resident Shareholder, Winnipeg
The situation — A non-resident shareholder drawing dividends, Winnipeg, Manitoba
A non-resident shareholder drawing dividends in Winnipeg, Manitoba had not filed for 7 years. The CRA had issued arbitrary assessments. The business was carrying a treaty tie-breaker position asserted on the return with no analysis behind it. That came on top of a growing interest balance.
What we did for A non-resident shareholder drawing dividends, Winnipeg, Manitoba
We started with the oldest year and worked forward so each year's closing balances fed the next. We mapped the residential ties on each side of the departure date and fixed the date residency actually ceased. We filed the emigrant return with the deemed disposition and the property list built on that date. We filed the years in sequence rather than all at once.
The result — A non-resident shareholder drawing dividends, Winnipeg, Manitoba
Every year is now filed and assessed on actual figures. The notional assessments were vacated and $13,500 of the estimated balance came off, with a payment arrangement covering the rest.
Client: A non-resident director of a Canadian corporation · Where: Ottawa, Ontario · Engagement: 6 weeks, fixed fee
Overpayment refunded$27,000
Late remittances sinceZero
ScheduleAutomated
The situation — A non-resident director of a Canadian corporation, Ottawa, Ontario
Remittances at a non-resident director of a Canadian corporation in Ottawa, Ontario were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat registered plan withdrawals taken after departure at the flat non-resident rate with no election ever considered.
What we did for A non-resident director of a Canadian corporation, Ottawa, Ontario
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. Then we moved the remittance dates into a scheduled process rather than a monthly decision.
The result — A non-resident director of a Canadian corporation, Ottawa, Ontario
Penalties stopped from the following remittance onwards, and $27,000 of overpaid instalments was refunded.
Case Study 6 · Cross-border exposure resolved
$83,000 Of Excess Withholding Refunded On Election — Departing Emigrant, Edmonton
Client: An emigrant severing Canadian ties · Where: Edmonton, Alberta · Engagement: 3 weeks, fixed fee
Withholding refunded$83,000
ElectionFiled and accepted
Cross-border reportingConsistent
The situation — An emigrant severing Canadian ties, Edmonton, Alberta
An emigrant severing Canadian ties in Edmonton, Alberta was paying tax in two countries on one stream of income. A T1135 filed for the year of arrival, when none was required, and none filed for the years that followed had never been reviewed against the treaty.
What we did for An emigrant severing Canadian ties, Edmonton, 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 coordinated the timing so the credit claimed in Canada matched the tax actually paid abroad.
The result — An emigrant severing Canadian ties, Edmonton, Alberta
$83,000 of excess withholding was refunded and the exposure closed. Both sides of the border now report consistently, which is what keeps the credit claimable.
