Ontario puts one harmonized tax on that work, compulsory workplace coverage that reaches the owner personally, and a statute that sets holdbacks and payment deadlines. EverStone is a [CPA for incorporated contractors](https://www.everstonecpa.com/contractor-accountant) and a [Kingston small-business accountant](https://www.everstonecpa.com/accountant-kingston), working remotely. [Get My Fixed Quote](https://www.everstonecpa.com/book-online)[Ask a Free Question](https://www.everstonecpa.com/quick-question) **Quick answer:** Trades companies in Kingston, Ontario charge a single 13% HST rather than separate federal and provincial taxes. Compulsory WSIB coverage extends to owners in construction, and statutory holdback and prompt payment rules apply to the work. EverStone prepares the corporate return, HST filings and T5018 slips remotely. For Kingston trades, published fees start at $300 a month for bookkeeping and $100 for a personal return. For a one-owner Kingston trades business, monthly bookkeeping, payroll and the year-end T2 with statements usually cost from $450 to $650 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. ## The work Kingston contractors do Kingston’s largest employers include Queen’s University, Kingston Health Sciences Centre, St. Lawrence College, Canadian Forces Base Kingston and the City of Kingston, and the buildings those institutions run need constant maintenance, renovation and new work. Around them sits ordinary residential and commercial construction across the city and out into Amherstview, Napanee, Gananoque and Frontenac County. The city’s focus on sustainable manufacturing brings industrial work too. A typical Kingston trades company does some mix of these: homeowner renovations paid directly, subcontract work for a general contractor on a larger project, and service calls. Each kind of work carries a different accounting pattern. Homeowner jobs are quick to bill and quick to pay. Subcontract work on larger projects comes with progress billing, holdbacks and payment certified by someone else. Institutional work can involve bid documents that ask for financial statements, proof of WSIB standing and insurance. Getting the books to support all three is most of the job. ## One tax on the invoice, and the cash it leaves in your account Ontario applies a single [13% harmonized sales tax](https://www.everstonecpa.com/ontario-tax-facts) rather than a federal tax plus a separate provincial one. For a trades business that is a genuine simplification: the tax is charged on the supply and recovered on the inputs, and there is no question of provincial tax being buried inside the cost of materials. What replaces it is a cash question. The full 13% is collected on every progress billing, and the tax on materials, tools and subtrades is recovered when the return is filed. Between remittances a busy contractor holds a lot of money that belongs to the CRA. Money held is money that gets spent, unless the process prevents it — which is why we recommend a separate account for HST. See the [input tax credits guide](https://www.everstonecpa.com/blog/input-tax-credits-itc-canada-guide). ## Compulsory coverage reaches the owner Ontario extends mandatory workplace insurance into construction at the ownership level. Under the province’s compulsory coverage rules, independent operators, sole proprietors, partners and executive officers of corporations carrying on business in construction generally must register with the WSIB and carry coverage. The exceptions are limited; the notable one is a business that does only home renovation work for a homeowner who hires and pays it directly. Employees always require coverage. For an owner-operator new to Ontario, or a tradesperson who has just incorporated, this is the obligation most often missed — and a general contractor or an institution will usually ask for a WSIB clearance before paying. ## Statutory holdback and a payment clock Ontario’s construction legislation requires a portion of the contract price to be held back on a project, sets prompt payment obligations that follow a proper invoice, and provides for adjudication of payment disputes. The accounting effect of a holdback is the same as anywhere: earned revenue that is not yet collectible sits in receivables, and holdbacks retained from your own subtrades are costs already incurred, belonging in the period the work happened. HST on a holdback generally becomes payable when the holdback is paid or payable, so billings and holdbacks have to be tracked separately. The payment rules add something specific: the invoice, and what makes it a proper one, starts a clock. Billing that was merely untidy becomes billing that delays money. ## Subtrade reporting is federal, and applies here too The **[T5018](https://www.everstonecpa.com/blog/t5018-subcontractor-reporting-construction)** requirement is federal, so a Kingston construction business that pays others for construction services reports those payments to the CRA. The underlying question — is this person a subtrade or an employee — matters as much as the slip. The factors are control, ownership of tools, ability to subcontract and chance of profit or loss, and the cost of guessing wrong lands on the payer as unremitted CPP, EI and income tax. A helper paid by the day under your direction, using your tools, is probably an employee whatever the invoice says. The [worker classification guide](https://www.everstonecpa.com/blog/employee-vs-contractor-cra-worker-classification) sets out the tests. ## Trucks, tools and the CCA schedule Trades companies buy a lot of equipment, and none of it is expensed in full in the year it is bought. Trucks, trailers, tools and machinery are claimed through [capital cost allowance](https://www.everstonecpa.com/glossary#cca) at the rate set by their class. Timing matters: an asset bought before year-end and available for use can start its CCA claim in that year. A vehicle used for both business and personal driving needs a log separating the two, because the log is what supports the claim. We plan larger purchases with you before the year closes rather than reading about them afterwards. ## Instalments, seasonality and a winter build window Kingston’s building season is shaped by winter. Revenue arrives unevenly, while tax obligations arrive on a calendar. [Corporate instalments](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/corporation-payments/paying-instalments.html) set from a prior-year formula routinely mismatch a construction company’s actual cash. A strong season can create both a large [balance owing](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/corporation-payments.html) and an instalment schedule that starts before the next season’s receivables arrive. Modelling that in the autumn is straightforward; discovering it in the spring is not. A fiscal year-end chosen just after the busy season can also make the year-end count and planning easier. See [corporate tax instalments](https://www.everstonecpa.com/blog/corporate-tax-installments-canada). ## 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 - Payroll, WSIB reporting and instalment planning built around the season ## Remote, and there is no Kingston office EverStone has no Kingston location.

Common questions ## Kingston trades accounting FAQ **Do Kingston contractors charge HST on construction work?** Yes, once registered. Ontario applies a single 13% harmonized tax on the supply, and registrants recover the tax paid on materials, tools and subtrades through input tax credits. The practical issue is the cash held between remittances. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Does an owner-operator in Ontario construction need WSIB coverage?** Generally yes. Ontario’s 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 you retain holdback from your own subtrades. Both belong in the period the work was performed. Deferring either to the release date misstates the margin on the job. **Why does invoice quality matter more in Ontario?** Because the province’s construction legislation ties prompt payment obligations to a proper invoice, so the document itself starts a timeline and can support an adjudication if payment does not follow. Invoice discipline becomes a working-capital issue rather than an administrative one. **Do T5018 slips apply in Ontario?** Yes — the requirement is federal, so the province makes no difference. A construction business that pays others for construction services generally reports those payments, and the subtrade-versus-employee question has to be answered first. **When should a Kingston tradesperson incorporate?** Usually once the business earns more than the owner needs to live on, so profit can be left in the company at the small-business rate. Incorporating also brings a T2, a registry return and WSIB as an executive officer, so the saving has to be worth the extra filings. We run the numbers with you. **Can a CPA working online file for a Kingston company?** Yes. The engagement is delivered by video call, e-signature and secure upload, and there is no Kingston office. Corporate income tax is federal legislation with a provincial layer, so what matters is that the T2, the HST filings and the books come from one consistent set of records. **Do you work with trades businesses outside Kingston itself?** Yes. Trades businesses in Amherstview, Napanee, Gananoque and across Frontenac County are served the same way as those in Kingston, remotely and at the same fixed fees. ## Related services and local guides Nearby cities, the rest of what we do for Kingston businesses, and the reference pages behind this one.
