Corporate Tax Filing Case Studies

6 Corporate Tax Filing 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 corporate tax filing work, not a general example.

Case Study 1 · Missed incentive claimed

Incentive Review Recovered $25,000 Across 5 Open Years — First-Year Startup, Vancouver

Client: A first-year startup  ·  Where: Vancouver, British Columbia  ·  Engagement: 11 weeks, fixed fee

Recovered$25,000
Open years claimed5
Ongoing trackingIn place

The situation

An incentive review at a first-year startup in Vancouver, British Columbia started from a simple question: what has never been claimed? The answer ran to 5 years, driven by filings handled by three different providers with no continuity between them.

What we did

We rebuilt the supporting records, corrected the affected filings, and set a compliance calendar covering every deadline the business actually carries, documenting eligibility to the standard a reviewer would apply rather than the standard a claim form requires.

The result

The credits produced $25,000 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.

Case Study 2 · Sale and succession

Intergenerational Transfer Completed With $575,000 Deferred — Family Enterprise, London

Client: A family enterprise  ·  Where: London, Ontario  ·  Engagement: 9 weeks, fixed fee

Tax deferred$575,000
TransferCompleted
RecordsReview-ready

The situation

A generational transfer at a family enterprise in London, Ontario had been discussed for years without a plan. Passive assets sitting inside the operating company, disqualifying the shares meant the transfer as contemplated would have been fully taxable.

What we did

We consolidated the work into a single engagement so the corporate, sales tax and payroll filings finally reconciled to each other, sequencing the steps so each one was complete and documented before the next depended on it.

The result

$575,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.

Case Study 3 · Backlog brought current

Collections Halted And $130,000 Cut From A 7-Year Backlog — Professional Practice, Barrie

Client: A professional practice  ·  Where: Barrie, Ontario  ·  Engagement: 7 weeks, fixed fee

Balance reduced by$130,000
Backlog cleared7 years
CollectionsHalted

The situation

By the time a professional practice in Barrie, Ontario called, 7 years were outstanding and the CRA had assessed on estimates. Underneath it sat a balance that had been accruing daily compound interest for two years.

What we did

We reconstructed the records year by year and documented the positions taken, retained the supporting analysis, and prepared the file so a review could be answered in days rather than weeks. Each filing replaced an arbitrary assessment with a real one.

The result

The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $130,000, and a relief application addressed part of the accumulated interest.

Case Study 4 · Structure rebuilt

Reorganisation Completed Tax-Deferred, $67,000 Saved Each Year — Growing Small Business, Ottawa

Client: A growing small business  ·  Where: Ottawa, Ontario  ·  Engagement: 11 weeks, fixed fee

Annual saving$67,000
Tax on reorganisationDeferred
Elections filedOn time

The situation

A growing small business in Ottawa, Ontario had outgrown the structure it started with. Positions taken on prior returns that nobody could explain or support 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 brought the outstanding filings current and negotiated an arrangement that stopped the interest from compounding further — 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 $67,000 a year while removing the exposure the old one carried.

Case Study 5 · Objection and relief

Desk-Review Assessment Of $91,000 Vacated — Owner-Managed Corporation, Regina

Client: An owner-managed corporation  ·  Where: Regina, Saskatchewan  ·  Engagement: 4 weeks, fixed fee

Assessment vacated$91,000
Supporting recordsNow on file
AccountCleared

The situation

An owner-managed corporation in Regina, Saskatchewan was carrying $91,000 of penalties and interest arising from filings handled by three different providers with no continuity between them, much of it accumulated during a period the CRA itself had delayed.

What we did

We rebuilt the supporting records, corrected the affected filings, and set a compliance calendar covering every deadline the business actually carries and framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.

The result

The assessment was vacated. $91,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.

Case Study 6 · Deadline rescue

6-Week Turnaround Beat The Deadline And Saved $92,000 — Independent Retailer, Lethbridge

Client: An independent retailer  ·  Where: Lethbridge, Alberta  ·  Engagement: 6 weeks, fixed fee

Late-filing penalty avoided$92,000
Filed with13 days to spare
Next yearPapers ready

The situation

With the deadline for corporate tax filing weeks away, an independent retailer in Lethbridge, Alberta was carrying records that could not support the positions already taken on filed returns. The exposure if the date slipped was around $92,000.

What we did

We consolidated the work into a single engagement so the corporate, sales tax and payroll filings finally reconciled to each other. The filing went in complete rather than provisional, so there was no amended return to follow.

The result

Filed with 13 days to spare. $92,000 in late-filing penalties avoided, and the working papers are ready for the following year.
