Corporate tax accountant for Montreal corporations

Quebec, like Alberta, runs its own corporate income tax return. A Montreal company files a T2 with the CRA and a CO-17 with Revenu Québec, from the same year-end. EverStone prepares both remotely, in English. See the Quebec overview or the Montreal practice.

Quick answer: A Montreal corporation files the federal T2 with the CRA and the Quebec CO-17 with Revenu Québec, both due six months after year-end, with any balance owing due two or three months after year-end. On the Quebec side, the small business deduction depends on 5,500 paid hours in the year. EverStone prepares both returns and the financial statements behind them, remotely and in English, at a fixed fee. For a one-owner trades corporation, bookkeeping, payroll and the year-end T2 together usually run $450–$650 a month.

Two corporate returns, one set of statements

In most provinces, the provincial corporate tax rides inside the federal T2 and the CRA collects it. Quebec administers its own. A corporation with an establishment in Montreal files the T2 federally and the CO-17 with Revenu Québec, each with its own schedules, its own assessment and its own notice. The two returns start from the same financial statements, so the income, the reserves and the capital cost allowance have to agree unless a rule genuinely differs between them.

That is why the order of work matters. The books are closed once, the statements are prepared once, and both returns are built from them together. Preparing the T2 in June and the CO-17 in September from a trial balance that moved in between is how the two drift apart. A mismatch is exactly the kind of thing that prompts a question from one authority or the other. Filing a T2 covers the federal side in detail.

The Quebec small business deduction and the hours test

Federally, a Canadian-controlled private corporation claims the small business deduction on active business income under the usual conditions. Quebec adds its own condition: the corporation’s small business deduction depends on 5,500 paid hours in the year. For a Montreal consultancy, studio or design practice run by one or two people, that is often out of reach, and the Quebec rate on the same income is then the general one.

This is the single Quebec-specific number most owners have never heard of, and it changes the arithmetic of incorporating, of paying salary, and of leaving profit in the company. It is worth modelling before the year, not discovering on the CO-17. Hours paid to employees count, so a company that is hiring may reach the threshold sooner than it expects; one that runs on subcontractors generally will not.

Salary or dividends when payroll means QPP and QPIP

The salary-versus-dividend decision has a Quebec shape. Salary paid to an owner carries QPP rather than CPP, QPIP premiums, the employer’s Health Services Fund contribution and CNESST coverage, and it is deductible to the corporation on both returns. Dividends carry none of those, but they build no QPP entitlement and no RRSP room. Salary also counts toward the paid hours that the Quebec small business deduction depends on, which can tip the balance for a small company close to the line. The salary vs dividends calculator is a starting point; the Quebec layer is what the consultation adds.

Sales tax filed separately, reconciled at year-end

GST and QST are not part of either income tax return, but they are part of the same audit trail. For most Quebec businesses both are filed with Revenu Québec, on an annual, quarterly or monthly period assigned by revenue. An annual-filing corporation files and pays three months after year-end. At year-end, the revenue on the T2 and CO-17 should reconcile to the sales reported on the sales tax returns; a gap that cannot be explained is one of the first things a reviewer looks for. What a sales tax review checks sets out the usual questions.

Instalments and the shareholder loan

A Montreal corporation past its first profitable year generally moves onto instalments for both federal and Quebec tax, paid through the year rather than at filing. The base comes from prior-year figures, so a fast-growing company can pay far too little and meet a large balance, with interest, at filing — a balance due before the returns themselves. The owner’s side matters too: a shareholder loan not repaid within one year after the corporation’s year-end is generally taxed as the owner’s income, which means a T1 and a TP-1 both reopen. Both questions are settled before the year closes. Corporate tax instalments covers the federal rules.

Working with a CPA outside Quebec, in English

EverStone is a one-CPA firm in Abbotsford, British Columbia. There is no Montreal office, no branch and no local staff. The T2 is transmitted to the CRA and the CO-17 to Revenu Québec electronically, under rules that do not depend on where the preparer sits. EverStone works in English: the planning conversation, the draft statements and the explanation of what each return says are all in English. The engagement runs by secure upload link, video calls in Eastern time and e-signature, with the same CPA on the file from the first question to both filed returns.

Year-end planning only works against a number you set earlier, which means a budget built from the operations rather than a guess in December.

Common questions

Montreal corporate tax questions

Does a Montreal corporation file two tax returns?+
Yes. It files the federal T2 with the CRA and the Quebec CO-17 with Revenu Québec. Both are due six months after year-end and both are prepared from the same financial statements. Ask about your case →
Why is my Quebec tax higher than I expected?+
Often because of the hours test. Quebec’s small business deduction depends on 5,500 paid hours in the year, and a corporation with one or two people frequently falls short, so its income is taxed at the general Quebec rate.
Is it better to pay myself salary or dividends in Quebec?+
It depends on your numbers. Salary brings QPP, QPIP and the employer’s Health Services Fund contribution, but it is deductible, builds RRSP room and counts toward the Quebec paid-hours test. Dividends avoid the payroll costs but build neither. It is modelled for your company before the year-end.
When is corporate tax due?+
The balance is generally due two months after year-end, or three for a CCPC claiming the small business deduction that meets the conditions. The returns follow at six months. Interest runs from the balance date, not the filing date.
Do you work in English?+
Yes. EverStone works in English for Montreal corporations, from the free consultation through the filed returns.
Do you have a Montreal office?+
No. EverStone works from a single office in Abbotsford, British Columbia, and serves Montreal corporations entirely remotely. Documents come through a secure upload link, returns are e-signed, and no office visit is required at any stage.
What does a corporate tax return cost in Montreal?+
The fee is the same in Montreal as anywhere else EverStone works. A T2 on its own is quoted after a free consultation, once the books have been seen. For a one-owner trades corporation, bookkeeping, payroll and the year-end T2 with statements together usually run $450 to $650 a month all-in. See the published fees.
Do you work with businesses outside Montreal itself?+
Yes. Corporations based in Laval, Longueuil, the West Island and the South Shore have their T2 prepared exactly as Montreal ones do, remotely and at the same fixed fee.

Who this is for, and who it is not

This fits an incorporated business in Montreal that wants one CPA on both corporate returns, a fee agreed in writing before any work starts, and a year end that arrives on a schedule rather than as a surprise. It is not the right fit if the lowest possible price matters more than anything else, if you need someone sitting in your office each week, or if you want your accountant to work in French. The engagement runs by video call, secure upload and e-signature, and the fee is the same wherever you are.

What happens when you get in touch

A Montreal corporation is onboarded the same way as one next door, and on the same fixed fee.

  1. 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.
  2. Authorization, in the first week. We are authorized with the CRA and with Revenu Québec, so balances and notices are looked up rather than requested from you. If you are switching firms, your file is requested the same week.
  3. Current, then ahead. Books brought to a closing position, anything overdue scheduled oldest year first, and the next twelve months of T2, CO-17 and instalment dates set before they arrive.

Book the free consultation, or ask one question first — both reach a CPA, not a queue.
