Construction accounting and trades accountant in Toronto

Ontario runs construction on a different set of rails from British Columbia. There is one harmonized tax instead of two, and compulsory workplace coverage that reaches the owner personally. A statute sets the payment deadlines. Those three differences shape the construction accounting Toronto trades need, and each one is covered below.

EverStone is a CPA for incorporated contractors and a Toronto small-business accountant, working remotely.

Quick answer: Trades companies in Toronto, Ontario charge a single harmonized tax rather than separate federal and provincial ones. Compulsory workplace coverage extends to owners in construction. Statutory holdback and prompt payment obligations apply to the work. EverStone prepares the corporate return, HST filings and subtrade slips remotely. Published fees start at $325 a month for bookkeeping and $125 for a personal return.

For a one-owner Toronto trades business, monthly bookkeeping, payroll and the year-end T2 with statements usually cost from $500 to $700 a month all-in. The year-end covers the T2 with Schedule 1 and Schedule 50, the CCA schedule, the small business deduction, T4 or T5 slips for the owner’s pay, and the instalments for the year ahead.

Ontario replaces a trades company’s provincial sales tax judgement with a single 13% harmonised tax, but adds compulsory workplace coverage reaching owners in construction, statutory holdback and prompt payment obligations, and a cash-flow problem created by holding the full tax on progress billings between remittances

One tax on the invoice, not two decisions

Ontario applies a single 13% harmonized sales tax instead of separate federal and provincial taxes. That removes the question that dominates BC estimating: whether provincial tax on a contract is a cost inside the price or a line on the invoice. In Ontario the tax is charged on the supply and recovered on the inputs.

What replaces that question is a cash-flow one. The full amount is collected on progress billings, and the input side is recovered on filing. So a Toronto contractor holds significantly more tax money between remittances than a BC contractor does. Money held is money that gets spent, unless the process prevents it. See the input tax credits guide.

Compulsory coverage reaches the owner

Ontario extends mandatory workplace insurance in construction to owners. Independent operators, sole proprietors, partners and executive officers of construction businesses generally must register and carry coverage. The main exception is a business doing only home renovation for a homeowner who hires and pays it directly.

Owner-operators arriving from other provinces miss this most often, because elsewhere an owner without employees has nothing to register. Employees always need coverage.

Statutory holdback and a payment clock

Ontario’s construction legislation requires a project holdback, sets prompt payment obligations triggered by a proper invoice, and provides adjudication of payment disputes. The accounting is the same as anywhere: earned but uncollectible revenue sits in receivables, and holdbacks retained from subtrades are costs already incurred, in the period the work happened.

The payment rules have a specific effect: a proper invoice starts a clock. Sloppy billing becomes billing that delays money.

Subtrade reporting is federal, and applies here too

The T5018 rule is federal: an Ontario construction business reports payments for construction services just as a BC one does. Toronto’s long tail of small specialized subtrades makes the subtrade-or-employee question more live. It turns on control, ownership of tools, ability to subcontract and chance of profit or loss, and a wrong guess costs the payer. An accountant for construction companies should settle those classifications before the subtrade slips are prepared, not after the CRA asks.

Instalments, seasonality and a compressed build window

Winter compresses Toronto’s building season, so revenue arrives unevenly while tax arrives on a calendar. Corporate instalments set from a flat prior-year formula routinely mismatch a construction company’s cash. A strong season can create both a large balance owing and instalments that start before the next season’s receivables. Modelling that in autumn is easy; discovering it in spring is not. See corporate tax instalments.

What is covered

One Chartered Professional Accountant handles the whole file:

  • T2 corporate return and year-end financial statements
  • HST registration, filing and input tax credit reconciliation
  • Statutory holdback schedules, receivable and payable sides
  • T5018 information returns and worker classification review
  • Job-costed bookkeeping and progress billing cut-off
  • Instalment planning built around the actual draw calendar

Remote, and there is no Toronto office

EverStone has no Toronto location. Ontario engagements run entirely online: video meetings, e-signature and secure document exchange. Corporate tax is federal law with a provincial layer, so the work is not tied to a postcode. See accounting for Ontario businesses.

Common questions

Toronto trades accounting FAQ

Do Toronto contractors charge HST on construction work?+
Ontario applies a single 13% harmonized tax on the supply rather than separate federal and provincial taxes, and registrants recover the tax paid on inputs. That removes the BC question of whether provincial tax is a buried cost or an invoice line, but it means more tax money is held between remittances. Ask about your case →
Does an owner-operator in Ontario construction need WSIB coverage?+
Generally yes. Ontario’s expanded compulsory coverage rules extend registration and coverage to independent operators, sole proprietors, partners and executive officers carrying on business in construction. A limited exception covers businesses doing only home renovation work for a homeowner who hires and pays them directly. Employees always require coverage.
What does the statutory holdback do to the books?+
It creates earned revenue that is not yet collectible on the receivable side, and costs already incurred on the payable side where a company retains holdback from its own subtrades. Both belong in the period the work was performed. Deferring either to the release date misstates the margin on the job that produced it.
Why does invoice quality matter more in Ontario?+
The province’s construction legislation ties prompt payment to a proper invoice, so the document starts a timeline and can support adjudication if payment does not follow. Untidy billing then delays cash, which makes invoice discipline a working-capital issue.
Do T5018 slips apply in Ontario?+
Yes — the requirement is federal, so province makes no difference. A construction business that pays others for construction services generally reports those payments. Toronto work often involves a long tail of small specialized subtrades, which makes the subtrade-versus-employee question more live rather than less.
Can a CPA in British Columbia file for a Toronto company?+
Yes. The engagement is delivered remotely by video call, e-signature and secure upload, and there is no Toronto office. Corporate income tax is federal legislation with a provincial layer, so what matters is that the corporate return, the HST filings and the books are all prepared from one consistent set of records.
Do you work with businesses outside Toronto itself?+
Yes. Trades businesses in Mississauga, Brampton, Vaughan, Markham and the rest of the GTA are served the same way as those in Toronto, remotely and at the same fixed fees.
