Inventory Valuation Correction – Margins & Tax Restored

A manufacturer's inventory was mis-valued, distorting profit. We corrected the valuation and the tax that flowed from it.

What happened

A manufacturer valued inventory inconsistently, distorting cost of goods sold and reported profit across years. We implemented lower-of-cost-and-net-realisable-value costing, restated the affected periods, and filed the necessary adjustments. The correction gave accurate margins and aligned taxable income with reality.

Manufacturing turns on inventory valuation, capital cost allowance on production equipment and the split between M&P and other income.

The rules this turned on

Inventory valuation

Inventory is valued at the lower of cost and net realisable value, applied consistently. Changing method without CRA consent reopens prior years.

Why it bites: Obsolete stock carried at cost overstates income, and the write-down is usually taken years after it was justified.

Books and records

The CRA requires business records to be kept for six years from the end of the tax year they relate to, in a form that allows the return to be verified.

Why it bites: Where records cannot support the return, the CRA is entitled to assess on its own estimate — and the burden of disproving that estimate falls on the taxpayer.

Corporate tax (T2)

A CCPC files its T2 within six months of year-end, with the balance due two months after (three where the small business deduction is claimed). The 9% federal small business rate applies to the first $500,000 of active business income.

Why it bites: The filing and payment deadlines differ, and interest runs from the payment date. Filing on time while paying late still costs money.

What this means for your business

Every engagement above was priced as a fixed fee agreed before the work started, and paid only once the client had reviewed the result. If any of this looks like your situation, the first step is a free 15-minute call — we will tell you plainly whether there is anything worth doing.
