Corporate tax accountant for Quebec City corporations
Quebec is the one province that collects its own corporate income tax, so a Quebec City company files the federal T2 and a separate CO-17, each assessed on its own. EverStone prepares both remotely, in English. See the Quebec overview or the Quebec City practice.
Quick answer: A Quebec City corporation files a T2 with the CRA and a CO-17 with Revenu Québec, both due six months after year-end, with the balance owing two or three months after year-end. Quebec’s small business deduction depends on 5,500 paid hours in the year, a condition the federal deduction does not have. EverStone prepares both returns from one file, remotely and in English, at a fixed fee quoted after a free consultation. For a one-owner trades corporation, bookkeeping, payroll and the year-end T2 together usually run $450–$650 a month.
Two returns, two assessments
In every other province, the provincial corporate tax is calculated on schedules inside the federal T2 and collected by the CRA. Quebec administers its own. A Quebec City corporation therefore files the T2 federally and the CO-17 with Revenu Québec, and receives two notices of assessment. Both returns begin with the same financial statements, but each has its own adjustments, credits and schedules. The discipline that matters is keeping them reconciled: an expense disallowed on review by one administration should be reflected in the other, and a reassessment on one side is worth checking against the other before the objection window closes. A notice of objection to the CRA is due within 90 days of the notice of assessment.
The 5,500-hour condition
The federal small business deduction turns on control, active business income and the business limit. Quebec’s version adds a test of its own: the provincial deduction depends on the corporation having 5,500 paid hours in the year. That catches corporations the federal rules treat as ordinary small businesses. A consultant’s one-person corporation, a holding structure with a single employee, or a young startup with two founders drawing little salary can all fall short. The result is a higher Quebec rate on income that is taxed at the low rate federally. Whether hours from associated corporations or from the shareholders themselves count depends on the facts, which is why the question belongs in planning, before the year ends, rather than at filing.
Balance due before the return is filed
Both returns are due six months after the fiscal year-end, but the tax is due earlier: two months after year-end, or three for a Canadian-controlled private corporation claiming the small business deduction that meets the conditions. Interest runs from the balance-due date, not the filing date, so a return filed on time can still carry interest if the payment was late. Once the corporation is profitable, instalments are generally required through the year to both administrations. Instalments built on last year’s tax overshoot in a weak year and fall short in a strong one; revising them as the year unfolds keeps cash where it is useful. Corporate instalments sets out the mechanics.
Paying yourself from a Quebec corporation
An owner-manager in Quebec City chooses between salary and dividends with Quebec rules on both sides. Salary is deductible to the corporation, brings QPP contributions and RL-1 slips, and adds Health Services Fund and CNESST costs. Dividends avoid payroll costs but are paid from after-tax profit and do not build QPP entitlement. Salary also affects the paid-hours count that Quebec’s small business deduction depends on. Amounts taken out informally sit in the shareholder loan account, and a loan not repaid within one year after the corporation’s year end is generally taxed as the owner’s income. Salary versus dividends explains the federal side; the Quebec layer is modelled on your actual numbers.
Sales tax and the corporate year end
A Quebec City corporation collects 5% GST and 9.975% QST, and for most Quebec businesses both are administered by Revenu Québec. An annual filer’s sales tax returns are due three months after year-end, close to the corporate balance-due date. The year-end file should reconcile GST and QST collected to reported revenue, and input tax credits and input tax refunds to recorded expenses. A mismatch between the sales tax returns and the corporate returns is one of the simplest things for an administration to spot, and one of the easiest to prevent.
Corporations in the capital’s main industries
The corporate file changes shape by industry. Contractors carry holdbacks, work in progress and T5018 reporting into the year end. Consultants contracting with a public body need their personal services business risk reviewed, because a corporation that looks like an employee loses the small business deduction entirely. Tech startups claim SR&ED on Form T661 alongside the T2, and a CCPC can earn the enhanced refundable credit. Restaurants and retailers close on an inventory count that sets cost of sales for both returns.

Who this is for, and who it is not
This suits an owner-managed Quebec City corporation that wants the T2 and CO-17 prepared by the same person, a price settled before anything begins, and planning done while the year is still open. It suits owners who would rather discuss their company in English. It does not suit anyone shopping purely on the lowest fee, a company that wants an accountant on its premises every week, or a file that has to be handled in French. Meetings are by video, documents arrive by secure upload and signatures are electronic, and the published fees do not change with distance.
What happens when you get in touch
Three steps take a Quebec City corporation from first call to a calendar that runs ahead of its deadlines.
- A free thirty-minute conversation. What the company does, what has been filed, and what is overdue. You leave with a fixed fee in writing and no obligation to take it.
- Access to both administrations. You give us CRA authorization and a separate Revenu Québec authorization, so notices, instalment balances and prior assessments can be read directly. Moving from another firm? The switch starts with a request for last year’s working papers.
- Caught up, then scheduled. Late years are filed in order, the books reach a clean closing balance, and every federal and Quebec due date for the coming year goes on the calendar.
