Section 116 Certificate of Compliance Case Studies
6 worked Section 116 Certificate of Compliance 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 section 116 certificate of compliance work, not a specific client's file.
Case Study 1 · Scaling without breaking
Second-Province Expansion Handled, $16,000 Of Cash Released — US-Facing Canadian Corporation, Windsor
Client: A Canadian corporation with US customers · Where: Windsor, Ontario · Engagement: 11 weeks, fixed fee
Cash released$16,000
New registrationsComplete on day one
Compliance gapsNone
The situation — A Canadian corporation with US customers, Windsor, Ontario
Revenue at a Canadian corporation with US customers in Windsor, Ontario was up sharply and cash was tighter than ever. Underneath it sat foreign accounts that had passed the $100,000 T1135 threshold three years earlier.
What we did for A Canadian corporation with US customers, Windsor, Ontario
We filed the outstanding T1135 disclosures through the Voluntary Disclosures Program, which eliminated the penalty exposure entirely. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing.
The result — A Canadian corporation with US customers, Windsor, Ontario
$16,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
Case Study 2 · Cross-border exposure resolved
$142,000 Of Excess Withholding Refunded On Election — Florida Property Owner, Kitchener
Client: A family with a Florida vacation property · Where: Kitchener, Ontario · Engagement: 9 weeks, fixed fee
Withholding refunded$142,000
ElectionFiled and accepted
Cross-border reportingConsistent
The situation — A family with a Florida vacation property, Kitchener, Ontario
A family with a Florida vacation property in Kitchener, Ontario was paying tax in two countries on one stream of income. A US LLC taxed as a corporation in Canada, producing double tax on the same income had never been reviewed against the treaty.
What we did for A family with a Florida vacation property, Kitchener, Ontario
We reported the deemed disposition properly on the departure return and claimed the foreign tax credits that had been left unused. We also coordinated the timing so the credit claimed in Canada matched the tax actually paid abroad.
The result — A family with a Florida vacation property, Kitchener, Ontario
$142,000 of excess withholding was refunded and the exposure closed. Both sides of the border now report consistently, which is what keeps the credit claimable.
Case Study 3 · Sale and succession
Intergenerational Transfer Completed With $545,000 Deferred — Inbound Assignee, Burnaby
Client: An inbound transferee on assignment · Where: Burnaby, British Columbia · Engagement: 6 weeks, fixed fee
Tax deferred$545,000
TransferCompleted
RecordsReview-ready
The situation — An inbound transferee on assignment, Burnaby, British Columbia
A generational transfer at an inbound transferee on assignment in Burnaby, British Columbia had been discussed for years without a plan. Passive assets sitting inside the operating company, disqualifying the shares meant the transfer as contemplated would have been fully taxable.
What we did for An inbound transferee on assignment, Burnaby, British Columbia
We reconstructed the day count on both sides of the border and documented the residency and treaty position before either revenue authority asked. We sequenced the steps so each one was complete and documented before the next depended on it.
The result — An inbound transferee on assignment, Burnaby, British Columbia
$545,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
Case Study 4 · Objection and relief
$48,000 Of Penalties And Interest Cancelled On Relief — Non-Resident Landlord, Halifax
Client: A non-resident owning Canadian rental property · Where: Halifax, Nova Scotia · Engagement: 3 weeks, fixed fee
Penalties and interest cancelled$48,000
Relief groundsAccepted
AssessmentAdjusted to filed position
The situation — A non-resident owning Canadian rental property, Halifax, Nova Scotia
An assessment of $48,000 landed at a non-resident owning Canadian rental property in Halifax, Nova Scotia following a desk review. It turned on a departure year filed as a normal resident return with no deemed disposition reported. The auditor had not seen the records behind it.
What we did for A non-resident owning Canadian rental property, Halifax, Nova Scotia
We restructured the US holding so the Canadian and US characterisations aligned, ending the double taxation going forward. We then set out the legislative basis for the position alongside the documents supporting it.
The result — A non-resident owning Canadian rental property, Halifax, Nova Scotia
$48,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.
Case Study 5 · Cash and remittance control
$149,000 Of Working Capital Freed From The Tax Cycle — US Rental Owner, Winnipeg
Client: A Canadian resident with a US rental property · Where: Winnipeg, Manitoba · Engagement: 7 weeks, fixed fee
Working capital freed$149,000
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A Canadian resident with a US rental property, Winnipeg, Manitoba
A Canadian resident with a US rental property in Winnipeg, Manitoba was profitable on paper and short of cash every month. US tax paid but no foreign tax credit claimed on the Canadian return explained most of the gap.
What we did for A Canadian resident with a US rental property, Winnipeg, Manitoba
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. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A Canadian resident with a US rental property, Winnipeg, Manitoba
$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 6 · CRA review defended
Audit Defence Closed In 3 Weeks, $84,000 Cleared — US Branch Operator, Mississauga
Client: A Canadian corporation operating a US branch · Where: Mississauga, Ontario · Engagement: 3 weeks, fixed fee
Proposed tax cleared$84,000
Review duration3 weeks
OutcomeNo change
The situation — A Canadian corporation operating a US branch, Mississauga, Ontario
A Canadian corporation operating a US branch in Mississauga, Ontario was selected for review. Invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken had shown up in the CRA's automated matching. The proposed adjustment on section 116 certificate of compliance came to $84,000.
What we did for A Canadian corporation operating a US branch, Mississauga, Ontario
We aligned the Canadian and US reporting of the same income so the foreign tax credit claim carried support on both returns. Every figure in the response traced to a source record the auditor could verify without asking a second question.
The result — A Canadian corporation operating a US branch, Mississauga, Ontario
The review closed with no change. $84,000 of proposed tax came off the table, and the documentation now in place makes the next review a short one.
