6 Port Colborne tax and accounting engagements in full — what the client came to us with, what we did, and what it was worth. Each one is specific to Port Colborne and its provincial tax regime, not a general example.
Case Study 1 · Sale and succession
Share Sale Restructured, $270,000 Less Tax On Closing — Two-Dentist Practice, Port Colborne
Client: A two-dentist practice · Where: Port Colborne, Ontario · Engagement: 3 weeks, fixed fee
Tax saved on closing$270,000
PriceAs agreed
Post-closing adjustmentsNone
The situation
A two-dentist practice in Port Colborne, Ontario was preparing to sell. Due diligence surfaced a shareholder loan balance that would have been picked up as income on closing, which would have reduced the price or killed the deal outright.
What we did
We cleaned up the historical file, rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns, and prepared the due-diligence package the buyer's advisers actually asked for.
The result
The deal closed at the agreed price. $270,000 of tax was saved against the structure originally proposed, with no post-closing adjustment.
Case Study 2 · Structure rebuilt
Reorganisation Completed Tax-Deferred, $72,000 Saved Each Year — Recruitment Firm, Port Colborne
Client: A recruitment firm · Where: Port Colborne, Ontario · Engagement: 5 weeks, fixed fee
Annual saving$72,000
Tax on reorganisationDeferred
Elections filedOn time
The situation
A recruitment firm in Port Colborne, Ontario had outgrown the structure it started with. A provincial payroll levy that had never been registered for or remitted was the immediate problem; the longer-term one was that the structure blocked the next step.
What we did
We mapped the current structure, modelled the target, and assessed and claimed Ontario Innovation Tax Credit alongside the federal return — with the tax-deferred elections filed on time and the supporting valuations documented.
The result
The reorganisation completed without triggering tax, and the new structure saves approximately $72,000 a year while removing the exposure the old one carried.
Case Study 3 · Deadline rescue
8-Week Turnaround Beat The Deadline And Saved $127,000 — Family Medicine Clinic, Port Colborne
Client: A family medicine clinic · Where: Port Colborne, Ontario · Engagement: 8 weeks, fixed fee
Late-filing penalty avoided$127,000
Filed with15 days to spare
Next yearPapers ready
The situation
With the deadline for its on tax and accounting file weeks away, a family medicine clinic in Port Colborne, Ontario was carrying 13% HST charged on every sale regardless of where the customer was located. The exposure if the date slipped was around $127,000.
What we did
We recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year. The filing went in complete rather than provisional, so there was no amended return to follow.
The result
Filed with 15 days to spare. $127,000 in late-filing penalties avoided, and the working papers are ready for the following year.
Client: A translation services company · Where: Port Colborne, Ontario · Engagement: 8 weeks, fixed fee
Overpayment refunded$114,000
Late remittances sinceZero
ScheduleAutomated
The situation
Remittances at a translation services company in Port Colborne, Ontario were consistently late by a few days, which was enough to trigger penalties every quarter. Behind it sat sector-specific exposure the previous accountant had not seen before.
What we did
We assessed and claimed Ontario Made Manufacturing Investment Tax Credit alongside the federal return, then moved the remittance dates into a scheduled process rather than a monthly decision.
The result
Penalties stopped from the following remittance onwards, and $114,000 of overpaid instalments was refunded.
Case Study 5 · Scaling without breaking
Growth Handled Without A Missed Filing, $29,500 Freed — Physiotherapy Group, Port Colborne
Client: A physiotherapy group · Where: Port Colborne, Ontario · Engagement: 7 weeks, fixed fee
Cash freed$29,500
Compliance failuresNone
ReportingMonthly
The situation
A physiotherapy group in Port Colborne, Ontario was opening in a second province — different filing obligations, a different payroll regime, and out-of-province sales billed at the ON rate instead of the customer’s already in the file.
What we did
We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty and put monthly reporting in place so the owner could see the cash effect of growth while there was still time to act on it.
The result
Growth was absorbed without a compliance failure. $29,500 of cash was released, and the monthly reporting now flags a problem while it is still small.
Case Study 6 · Missed incentive claimed
Incentive Review Recovered $78,000 Across 4 Open Years — Surveying Practice, Port Colborne
Client: A surveying practice · Where: Port Colborne, Ontario · Engagement: 9 weeks, fixed fee
Recovered$78,000
Open years claimed4
Ongoing trackingIn place
The situation
An incentive review at a surveying practice in Port Colborne, Ontario started from a simple question: what has never been claimed? The answer ran to 4 years, driven by Ontario incentives claimed by competitors and never by this business.
What we did
We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns, documenting eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result
The credits produced $78,000 across the open years, and the tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
