6 worked Cornwall 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 Cornwall and its provincial tax regime, not a specific client's file.
Case Study 1 · Records and systems rebuilt
10 Months Reconciled And $17,000 Of Input Tax Recovered — Food Processing Plant, Cornwall
The situation — A food processing plant, Cornwall, Ontario
Nothing reconciled at a food processing plant in Cornwall, Ontario. Every filing started with 10 months of cleanup. The file was carrying out-of-province sales billed at the ON rate instead of the customer’s.
What we did for A food processing plant, Cornwall, Ontario
We rebuilt from source rather than correcting on top of the existing file. We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. Then we set the routine that keeps it clean.
The result — A food processing plant, Cornwall, Ontario
10 months reconciled to the bank. The close now takes 4 days, and $17,000 of previously unclaimable input tax was recovered in the process.

StructureMatches operations

We worked with the client's lawyer. Together, we assessed and claimed Ontario Innovation Tax Credit alongside the federal return. We also prepared the elections, resolutions and valuations the structure needed to stand up.
The result — An executive coaching practice, Cornwall, Ontario
The structure now matches the business. Annual saving of $25,000, and the reorganisation itself was tax-neutral.

We identified the qualifying activity and built the documentation to support it. Then we assessed and claimed Ontario Made Manufacturing Investment Tax Credit alongside the federal return.
The result — A translation services company, Cornwall, Ontario
$50,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
Case Study 4 · Planning that cut the bill
Remuneration Review Saved $19,500 Across Corporate And Personal Returns — Marketing Agency, Cornwall
The situation — A marketing agency, Cornwall, Ontario
Nothing was wrong at a marketing agency in Cornwall, 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 marketing agency, Cornwall, 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 marketing agency, Cornwall, Ontario
$19,500 came off the combined corporate and personal tax bill, and the structure holds for future years without further work.
Case Study 5 · Deadline rescue
3-Week Turnaround Beat The Deadline And Saved $19,000 — Management Consultancy, Cornwall
The situation — A management consultancy, Cornwall, Ontario
A management consultancy in Cornwall, Ontario was weeks away from the deadline for its ON tax and accounting file. Behind that sat 13% HST charged on every sale regardless of where the customer was located. The exposure if the date slipped was around $19,000.
What we did for A management consultancy, Cornwall, Ontario
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 — A management consultancy, Cornwall, Ontario
Filed with 12 days to spare. $19,000 in late-filing penalties avoided, and the working papers are ready for the following year.
Case Study 6 · Backlog brought current

Backlog cleared3 years
CollectionsHalted
The situation — A boutique law firm, Cornwall, Ontario
By the time a boutique law firm in Cornwall, Ontario called, 3 years were outstanding. The CRA had assessed on estimates. Underneath it sat out-of-province sales billed at the ON rate instead of the customer’s.
What we did for A boutique law firm, Cornwall, Ontario
We reconstructed the records year by year. We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. Each filing replaced an arbitrary assessment with a real one.
The result — A boutique law firm, Cornwall, Ontario
The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $36,000, and a relief application addressed part of the accumulated interest.
