6 worked Hamilton 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 Hamilton and its provincial tax regime, not a specific client's file.
Case Study 1 · Backlog brought current
5 Years Filed, $125,000 Removed From The Assessed Balance — IT Managed-Services Provider, Hamilton
Client: An IT managed-services provider · Where: Hamilton, Ontario · Engagement: 5 weeks, fixed fee
Years filed5
Assessed balance removed$125,000
CollectionsStopped
The situation — An IT managed-services provider, Hamilton, Ontario
An IT managed-services provider in Hamilton, Ontario had not filed for 5 years. The CRA had issued arbitrary assessments. The business was carrying sector-specific exposure the previous accountant had not seen before. That came on top of a growing interest balance.
What we did for An IT managed-services provider, Hamilton, Ontario
We started with the oldest year and worked forward so each year's closing balances fed the next. We assessed and claimed Ontario Made Manufacturing Investment Tax Credit alongside the federal return. We filed the years in sequence rather than all at once.
The result — An IT managed-services provider, Hamilton, Ontario
Every year is now filed and assessed on actual figures. The notional assessments were vacated and $125,000 of the estimated balance came off, with a payment arrangement covering the rest.
Case Study 2 · Planning that cut the bill
Remuneration Review Saved $44,000 Across Corporate And Personal Returns — Surveying Practice, Hamilton
Client: A surveying practice · Where: Hamilton, Ontario · Engagement: 3 weeks, fixed fee
Combined saving$44,000
ScopeCorporate + personal
Future yearsNo rework needed
The situation — A surveying practice, Hamilton, Ontario
Nothing was wrong at a surveying practice in Hamilton, 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 A surveying practice, Hamilton, 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 — A surveying practice, Hamilton, Ontario
$44,000 came off the combined corporate and personal tax bill, and the structure holds for future years without further work.
The situation — An investment advisory firm, Hamilton, Ontario
The structure at an investment advisory firm in Hamilton, Ontario needed fixing. The file was carrying 13% HST charged on every sale regardless of where the customer was located. Every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did for An investment advisory firm, Hamilton, Ontario
We worked with the client's lawyer. Together, we recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year. We also prepared the elections, resolutions and valuations the structure needed to stand up.
The result — An investment advisory firm, Hamilton, Ontario
The structure now matches the business. Annual saving of $51,000, and the reorganisation itself was tax-neutral.
Case Study 4 · Scaling without breaking

Cash freed$116,000
Compliance failuresNone
ReportingMonthly
The situation — A digital product agency, Hamilton, Ontario
A digital product agency in Hamilton, Ontario was opening in a second province. That meant different filing obligations and a different payroll regime. Out-of-province sales billed at the ON rate instead of the customer’s already sat in the file.
What we did for A digital product agency, Hamilton, Ontario
We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. 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 digital product agency, Hamilton, Ontario
Growth was absorbed without a compliance failure. $116,000 of cash was released, and the monthly reporting now flags a problem while it is still small.

Notice Of Objection Allowed In Full, $99,000 Reversed — Packaging Producer, Hamilton
The situation — A packaging producer, Hamilton, Ontario
A packaging producer in Hamilton, Ontario had been reassessed for $99,000. 21 days were left on the objection deadline. The reassessment rested on a provincial payroll levy that had never been registered for or remitted.
What we did for A packaging producer, Hamilton, Ontario
We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, we assessed and claimed Ontario Innovation Tax Credit alongside the federal return.
The result — A packaging producer, Hamilton, Ontario
The appeals officer allowed the objection in full. $99,000 was reversed and the account returned to a nil balance.
