Carpenters & Cabinetmakers Case Studies

6 worked Carpenters & Cabinetmakers 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 carpenters & cabinetmakers work, not a specific client's file.

Case Study 1 · Objection and relief

Desk-Review Assessment Of $38,000 Vacated — Commercial General Contractor, London

Client: A commercial general contractor  ·  Where: London, Ontario  ·  Engagement: 7 weeks, fixed fee

Assessment vacated$38,000
Supporting recordsNow on file
AccountCleared

The situation — A commercial general contractor, London, Ontario

A commercial general contractor in London, Ontario was carrying $38,000 of penalties and interest. The charges arose from sector deductions claimed on a general-business basis rather than the carpenters & cabinetmakers rules. Much of that amount accumulated during a period the CRA itself had delayed.

What we did for A commercial general contractor, London, Ontario

We aligned the reporting calendar with the sector’s own seasonal cycle rather than a generic year-end. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.

The result — A commercial general contractor, London, Ontario

The assessment was vacated. $38,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.

Case Study 2 · Cash and remittance control

The situation — A residential framing contractor, Guelph, Ontario

Remittances at a residential framing contractor in Guelph, Ontario were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat industry-specific reporting obligations nobody had flagged.

What we did for A residential framing contractor, Guelph, Ontario

We rebuilt the chart of accounts around how a carpenters & cabinetmakers business actually earns and spends. Then we moved the remittance dates into a scheduled process rather than a monthly decision.

The result — A residential framing contractor, Guelph, Ontario

Penalties stopped from the following remittance onwards, and $87,000 of overpaid instalments was refunded.

Case Study 3 · CRA review defended

Audit Defence Closed In 7 Weeks, $105,000 Cleared — Civil Works Company, Halifax

Proposed tax cleared$105,000
Review duration7 weeks
OutcomeNo change

The situation — A civil works company, Halifax, Nova Scotia

A civil works company in Halifax, Nova Scotia was selected for review. A previous accountant with no experience of this sector had shown up in the CRA's automated matching. The proposed adjustment on carpenters & cabinetmakers accounting and tax came to $105,000.

What we did for A civil works company, Halifax, Nova Scotia

We documented the positions to the standard the CRA applies to this sector specifically. Every figure in the response traced to a source record the auditor could verify without asking a second question.

The result — A civil works company, Halifax, Nova Scotia

The review closed with no change. $105,000 of proposed tax came off the table, and the documentation now in place makes the next review a short one.

Case Study 4 · Backlog brought current

6 Years Filed, $107,000 Removed From The Assessed Balance — Drywall Subcontractor, Barrie

Client: A drywall subcontractor  ·  Where: Barrie, Ontario  ·  Engagement: 4 weeks, fixed fee

Years filed6
Assessed balance removed$107,000
CollectionsStopped

The situation — A drywall subcontractor, Barrie, Ontario

A drywall subcontractor in Barrie, Ontario had not filed for 6 years. The CRA had issued arbitrary assessments. The business was carrying equipment and asset classes assigned by guesswork rather than the CCA schedule. That came on top of a growing interest balance.

What we did for A drywall subcontractor, Barrie, Ontario

We started with the oldest year and worked forward so each year's closing balances fed the next. We reassigned the asset classes on the CCA schedule and corrected the opening balances. We filed the years in sequence rather than all at once.

The result — A drywall subcontractor, Barrie, Ontario

Every year is now filed and assessed on actual figures. The notional assessments were vacated and $107,000 of the estimated balance came off, with a payment arrangement covering the rest.

Case Study 5 · Deadline rescue

11-Week Turnaround Beat The Deadline And Saved $139,000 — Concrete and Forming Crew, Hamilton

Client: A concrete and forming crew  ·  Where: Hamilton, Ontario  ·  Engagement: 11 weeks, fixed fee

Late-filing penalty avoided$139,000
Filed with16 days to spare
Next yearPapers ready

The situation — A concrete and forming crew, Hamilton, Ontario

A concrete and forming crew in Hamilton, Ontario was weeks away from the deadline for carpenters & cabinetmakers accounting and tax. Behind that sat seasonal revenue reported without matching the costs that produced it. The exposure if the date slipped was around $139,000.

What we did for A concrete and forming crew, Hamilton, Ontario

We reviewed every sector-specific deduction against the current rules and claimed the ones that had been missed. The filing went in complete rather than provisional, so there was no amended return to follow.

The result — A concrete and forming crew, Hamilton, Ontario

Filed with 16 days to spare. $139,000 in late-filing penalties avoided, and the working papers are ready for the following year.

Case Study 6 · Planning that cut the bill

First-year saving$67,000
RepeatsAnnually
Filing positionUnchanged in risk

The situation — An electrical contractor, Windsor, Ontario

An electrical contractor in Windsor, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left a chart of accounts that told the owner nothing about carpenters & cabinetmakers margin on the table.

What we did for An electrical contractor, Windsor, Ontario

We modelled the current position against the alternatives before changing anything. Then we aligned the reporting calendar with the sector’s own seasonal cycle rather than a generic year-end.

The result — An electrical contractor, Windsor, Ontario

The change saved $67,000 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
