The situation — A supplier with an off-calendar fiscal year-end, Lethbridge, Alberta
A supplier with an off-calendar fiscal year-end in Lethbridge, Alberta was paying instalments calculated on a prior year. That year no longer reflected the business. Capital assets written off in full in the year of purchase, with no fixed-asset schedule behind the deduction was tying up $120,000 of cash.
What we did for A supplier with an off-calendar fiscal year-end, Lethbridge, Alberta
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, we valued work in progress on one consistent basis and documented the method, so the comparative year could be relied on.
The result — A supplier with an off-calendar fiscal year-end, Lethbridge, Alberta
$120,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
Case Study 2 · Missed incentive claimed
Incentive Review Recovered $129,000 Across 6 Open Years — Two-Partner Engineering Firm, Windsor
The situation — A two-partner engineering firm, Windsor, Ontario
An incentive review at a two-partner engineering firm in Windsor, Ontario started from a simple question: what has never been claimed? The answer ran to 6 years. It was driven by a shareholder loan account that had drifted for three years with no supporting entries.
What we did for A two-partner engineering firm, Windsor, Ontario
We built a fixed-asset continuity schedule from the purchase invoices. We set the capital cost allowance claim class by class rather than claiming the maximum by default. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result — A two-partner engineering firm, Windsor, Ontario
The credits produced $129,000 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
Case Study 3 · Objection and relief
$136,000 Of Penalties And Interest Cancelled On Relief — Specialty Food Importer, Brampton
The situation — A specialty food importer, Brampton, Ontario
An assessment of $136,000 landed at a specialty food importer in Brampton, Ontario following a desk review. It turned on a year-end moved informally, leaving twelve months of trading reported as though nothing had changed. The auditor had not seen the records behind it.
What we did for A specialty food importer, Brampton, Ontario
We reconciled the inter-company accounts, papered the arrangement with a written agreement, and aligned both corporations’ year-ends. We then set out the legislative basis for the position alongside the documents supporting it.
The result — A specialty food importer, Brampton, Ontario
$136,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.
Case Study 4 · Planning that cut the bill

First-year saving$34,500
RepeatsAnnually
Filing positionUnchanged in risk
The situation — A commercial cleaning contractor, Surrey, British Columbia
A commercial cleaning contractor in Surrey, British Columbia was compliant but paying more than it needed to. The prior year had been filed correctly. It still left inter-company balances between two related corporations that had never been reconciled on the table.
What we did for A commercial cleaning contractor, Surrey, British Columbia
We modelled the current position against the alternatives before changing anything. Then we set a monthly close calendar with a fixed cut-off, so the year-end became a review of work already done rather than a twelve-month rebuild.
The result — A commercial cleaning contractor, Surrey, British Columbia
The change saved $34,500 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
Case Study 5 · Sale and succession

TransferCompleted
RecordsReview-ready
The situation — An owner-managed corporation preparing its first year-end, Mississauga, Ontario
A generational transfer at an owner-managed corporation preparing its first year-end in Mississauga, Ontario had been discussed for years without a plan. Retained cash well above what the business needed to operate meant the transfer as contemplated would have been fully taxable.
What we did for An owner-managed corporation preparing its first year-end, Mississauga, Ontario
We separated personal and corporate spending, cleared the shareholder loan through a documented salary and dividend mix, and restated the comparative year. We sequenced the steps so each one was complete and documented before the next depended on it.
The result — An owner-managed corporation preparing its first year-end, Mississauga, Ontario
$615,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
Case Study 6 · Deadline rescue
8-Week Turnaround Beat The Deadline And Saved $49,000 — Design Agency, Guelph
The situation — A 14-person design agency, Guelph, Ontario
A 14-person design agency in Guelph, Ontario was weeks away from the deadline for accounting internal controls review. Behind that sat work in progress carried at billing value one year and at cost the next, so neither year was comparable. The exposure if the date slipped was around $49,000.
What we did for A 14-person design agency, Guelph, Ontario
We rebuilt the trial balance from source documents, reconciled every bank and credit-card account, and issued a CSRS 4200 compilation with a proper basis-of-accounting note. The filing went in complete rather than provisional, so there was no amended return to follow.
The result — A 14-person design agency, Guelph, Ontario
Filed with 23 days to spare. $49,000 in late-filing penalties avoided, and the working papers are ready for the following year.
