Thunder Bay Case Studies

6 worked Thunder Bay 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 Thunder Bay and its provincial tax regime, not a specific client's file.

Case Study 1 · CRA review defended

$103,000 Reassessment Reduced To Nil On Review — Home-Care Nursing Agency, Thunder Bay

Client: A home-care nursing agency  ·  Where: Thunder Bay, Ontario  ·  Engagement: 8 weeks, fixed fee

Reassessment reduced toNil
Tax protected$103,000
Prior filingsUndisturbed

The situation — A home-care nursing agency, Thunder Bay, Ontario

A review notice arrived at a home-care nursing agency in Thunder Bay, Ontario, covering its ON tax and accounting file for two tax years. The auditor's working position was an adjustment of $103,000. It was driven by a provincial payroll levy that had never been registered for or remitted.

What we did for A home-care nursing agency, Thunder Bay, Ontario

Rather than negotiate, we rebuilt the record. We assessed and claimed Ontario Innovation Tax Credit alongside the federal return. We then submitted a point-by-point response that answered each proposed adjustment with the document behind it.

The result — A home-care nursing agency, Thunder Bay, Ontario

The auditor accepted the documented position and closed the review without adjustment, protecting $103,000 and leaving the prior filings undisturbed.

The situation — A data analytics consultancy, Thunder Bay, Ontario

4 years of unfiled returns had turned into notional assessments at a data analytics consultancy in Thunder Bay, Ontario. Underneath lay out-of-province sales billed at the ON rate instead of the customer’s. Collections had already started.

What we did for A data analytics consultancy, Thunder Bay, Ontario

We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. We then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.

The result — A data analytics consultancy, Thunder Bay, Ontario

All 4 years were accepted as filed. $13,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 4 years.

Relief applicationGranted
ReturnAccepted as filed

An executive coaching practice in Thunder Bay, Ontario had already missed one deadline and was about to miss a second. Behind it sat 13% HST charged on every sale regardless of where the customer was located. A penalty of $102,000 was accruing.

What we did for An executive coaching practice, Thunder Bay, Ontario

We split the work into what had to happen before the deadline and what could follow it. Then we recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year.

The result — An executive coaching practice, Thunder Bay, Ontario

The outstanding return was accepted as filed, and the taxpayer relief application cancelled $102,000 of the penalty already assessed on the earlier year.

Case Study 4 · Planning that cut the bill

Combined saving$72,000
ScopeCorporate + personal
Future yearsNo rework needed

The situation — An investment advisory firm, Thunder Bay, Ontario

Nothing was wrong at an investment advisory firm in Thunder Bay, Ontario. The filings were on time and accurate. What they were not was planned. Instalments still calculated on a year the business had long outgrown had never been reviewed.

What we did for An investment advisory firm, Thunder Bay, Ontario

We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns. We ran the numbers across both the corporate and personal returns, so the saving was real rather than deferred into someone else's hands.

The result — An investment advisory firm, Thunder Bay, Ontario

$72,000 came off the combined corporate and personal tax bill, and the structure holds for future years without further work.

StructureMatches operations

The situation — A metal fabrication business, Thunder Bay, Ontario
