Accountant for Oshawa manufacturers
Oshawa grew up around car assembly, and the automotive heritage left Durham with machine shops, tool and die makers, fabricators and parts suppliers whose numbers behave nothing like a service company’s. EverStone is a small business CPA serving Oshawa that works with production businesses remotely, at fixed fees.
Quick answer: A Durham manufacturer’s tax result depends on how inventory and work in progress are valued at year-end. It also depends on how jobs are costed, how machinery is claimed through capital cost allowance, and whether process-improvement work qualifies for SR&ED on Form T661. Larger payrolls add Ontario Employer Health Tax. For Oshawa businesses, EverStone handles the books, those calculations and the year-end T2 remotely, at a fee fixed before we start. Published fees start at $325 a month for bookkeeping and $125 for a personal return.
For a one-owner Oshawa manufacturer, bookkeeping, payroll and the year-end T2 with statements usually cost $500 to $700 a month. That covers Schedule 1 and Schedule 50, CCA, the small business deduction, owner T4 or T5 slips and instalments.

Inventory is a tax number, not just a count
For a shop with raw material, parts and finished goods, closing inventory is a top number on the return: overstated, profit comes early; understated, deductions do. Inventory is generally valued at the lower of cost and net realisable value, so obsolete parts and material for cancelled programs are written down.
Suppliers to larger manufacturers feel this most: when a program ends, its stock can lose most of its value overnight. We review slow and single-customer stock at year-end and book the write-down in the right year. The year-end count covers it.
Work in progress, and costing a job before you quote it
At year-end a job shop holds half-machined parts, assemblies awaiting components and shipped-but-unbilled orders. Work in progress carries their material, labour and overhead; misstate it and profit shifts years.
The same numbers drive quoting. Costing only material and direct labour makes every quote look good; adding machine time, setup, scrap and overhead shows what pays. We code costs to jobs where practical and compare results to quotes. The pricing and margin analysis service helps shops ready to reprice.
Big customers also squeeze cash: long terms, chargebacks and annual price-downs swell receivables, so profit and bank balance diverge. A monthly aged receivables review against supplier payments shows it early. See cash flow management and collecting receivables.
Machinery, capital cost allowance and the replacement cycle
CNC machines, presses, welders, forklifts and tooling are claimed through capital cost allowance. Manufacturing machinery gets favourable, recently changed treatment, so check class and timing before ordering. Assets must be available for use by year-end to count.
Selling or trading in a machine reduces its class, which can mean recapture or a terminal loss. We tie the CCA schedule to the real equipment list. See CCA classes and expensing for manufacturing buildings.
SR&ED on process improvement
Scientific Research and Experimental Development credits are not just for labs. Work through real technological uncertainty may qualify: a process for tighter tolerance, a non-obvious fixture that cuts cycle time, a tested material substitution. Claims go on Form T661 with the T2, and a Canadian-controlled private corporation can get an enhanced refundable credit, even with no tax owing.
Claims rest on records made at the time: the uncertainty, the attempts, the lessons. We help assess eligibility and keep supporting time and material records. See the SR&ED expenditure limit update.
HST on exports, and Employer Health Tax on a bigger crew
Many Durham shops export. Exports are generally zero-rated, so input HST is recovered with none charged, often leaving a refund each period. Documentation supports it; see HST on exports. Domestic sales carry 13% HST.
Shift and overtime payrolls often pass the Employer Health Tax exemption. The rate uses payroll before the exemption, and associated companies share one. See Ontario tax facts and payroll services in Oshawa.

What a Durham manufacturer has to get right
| Item | Why it matters |
|---|---|
| Closing inventory | Valued at the lower of cost and net realisable value; it moves profit between years |
| Work in progress | Material, labour and overhead already in unfinished jobs |
| Machinery CCA | Class and in-use date decide the deduction |
| SR&ED records | Claimed on Form T661; contemporaneous records carry the claim |
| Sales tax where you operate | 13% HST, a single registration and a single return |
