# Corporate tax accountant for *Ottawa* corporations


Ottawa corporate tax is often a geography question: staff or premises in Quebec end single-province filing. EverStone prepares [T2 returns](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/corporation-income-tax-return.html) remotely for [Ottawa businesses](https://www.everstonecpa.com/accountant-ottawa).

**Quick answer:** An Ottawa corporation reports Ontario tax inside its federal T2. One with a permanent establishment in Quebec must allocate taxable income between the two provinces. It also files a separate CO-17 with Revenu Québec. EverStone prepares those returns remotely at a fixed fee. A sole-shareholder trades company taking bookkeeping and payroll too would normally see $500–$700 a month, with the annual T2 inside that.


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.


Corporate tax specialist work for Ottawa corporations — the provincial allocation, the CO-17 and the T2 — is done by the same CPA, not handed down.


A real-estate decision that turns into a second corporate return.




## The river is the complication


Most Ottawa corporations are ordinary Ontario filers. The exceptions usually got there unnoticed: a small Gatineau office, an employee working from a Quebec address or any fixed place of business across the river can create a Quebec permanent establishment. Owners wanting one tax accountant in Ottawa for corporate and personal returns get both as one engagement.


Then taxable income must be allocated between Ontario and Quebec, and Quebec requires its own CO-17 return with Revenu Québec on top of the federal T2. Ottawa owners often discover this late; it is a filing obligation, not a choice. So a corporate tax return Ottawa companies with a Quebec establishment file is really two returns: the federal T2 and a separate CO-17 with Revenu Québec.



## How income gets divided between two provinces


With permanent establishments in more than one province, taxable income is not assigned by where invoices are raised or the bank account sits. A formula allocates it using gross revenue attributable to each establishment and salaries and wages paid at each. So a modest Quebec payroll can pull a meaningful share of income into a different provincial rate and a second return. The allocation follows how the business is arranged during the year, not anything done at year-end.


When it comes to corporate taxes Ottawa companies with even modest Quebec payroll can see a meaningful share of income taxed at a different provincial rate.



## Ontario’s share of the bill


Ontario side: 11.2% combined on active business income eligible for the [small business deduction](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4012.html) (9% federal plus Ontario’s 2.2% for days after 30 June 2026; 12.2% before, prorated by days in a straddling year). General income is taxed at 26.5% (15% plus 11.5%). Ontario’s employer health tax rate is set by band on total Ontario payroll before the $1,000,000 exemption. Ontario and Quebec payroll are measured separately for their own charges, so splitting a team across the river does not just split one bill.



## Selling to the federal government


Many small Ottawa corporations mainly serve a federal department or agency. The rate is unchanged, but two things follow. One or two departmental clients raise the same [personal services business](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4012.html) analysis as any single-client consultancy, which turns on control, tools and independent business risk, not who the customer is. And slow public payments often straddle a year-end, so work in progress and unbilled revenue decide which year the tax lands in.



## Payroll across two jurisdictions


An employee working in Quebec is not simply an Ontario employee with a different address. Provincial payroll obligations follow the place of employment, so a corporation with staff on both sides carries two sets of provincial requirements alongside the federal ones.


That means separate provincial registrations, remittances and year-end reporting, with payroll separating the two groups from the first pay run. It is usually the costliest administrative result of a Quebec establishment: what looks like a real-estate decision is a tax and payroll one.



## Year ends built around contract cycles


A year-end is chosen once and changed only with permission. If revenue follows public-sector procurement, ending the year after the main contract cycle gives cleaner figures: less unbilled work to estimate, receivables for completed work, and time to decide bonuses before the deduction deadline. [Choosing a fiscal year end](https://www.everstonecpa.com/blog/corporate-fiscal-year-end-canada-how-to-choose) covers the considerations; decide it at incorporation, as reversing it is hard.



## How a remote engagement works


EverStone is a fully virtual, one-CPA firm with no Ottawa office or local staff. The T2 and any provincial return follow the same rules wherever the preparer sits and are filed electronically, so everything runs remotely: secure upload, video review, e-signature. Using an out-of-province CPA explains authorization and filing across provinces.


An owner’s corporate and personal returns are decided together, and [personal tax in Ottawa](https://www.everstonecpa.com/personal-tax-accountant-ottawa) is the other half.


An allocation between Ontario and Quebec is easier to manage against a target, which [budgeting and forecasting](https://www.everstonecpa.com/budgeting-and-forecasting) sets well before December.

## Who this is for, and who it is not


Right for an Ottawa corporation, particularly one with Quebec activity, that wants the T2 and any CO-17 prepared by one CPA at a fee fixed in advance. Not right for anyone choosing only on price, or wanting a local desk to visit. The whole engagement is remote, on [published fees](https://www.everstonecpa.com/pricing).








## What happens when you get in touch


An Ottawa corporation is brought on in three steps.




- **No-fee introduction.** Thirty minutes on the company, where it operates and what is outstanding. Then a fixed fee in writing, with no obligation.

- **Federal authorization.** [CRA authorization](https://www.everstonecpa.com/forms/aut-01) gives direct access to balances and notices. [Switching accountants](https://www.everstonecpa.com/switching-accountants)? The file is requested that same week.

- **Filed, then forward.** Books are closed, overdue years filed oldest first, and the next [T2 and instalment deadlines](https://www.everstonecpa.com/t2-deadline) scheduled.

Common questions

## Ottawa corporate tax questions



**My company has an office in Gatineau. Does that change my filing?**

Yes. A permanent establishment in Quebec means taxable income must be allocated between the provinces, and Quebec administers its own corporate income tax, so a separate CO-17 return is filed with Revenu Québec alongside the federal T2. [Ask about your case →](https://www.everstonecpa.com/quick-question)



**How is income split between Ontario and Quebec?**

By a formula weighing gross revenue attributable to each permanent establishment against salaries and wages paid at each. It follows how the business is actually arranged during the year rather than where invoices are raised.



**Does one employee in Quebec create a permanent establishment?**

It can. A fixed place of business on the Quebec side is the clearest case, but it depends on the facts; settle it before year-end rather than when a return is prepared.



**What are the corporate rates for an Ottawa company?**

On the Ontario side, 11.2% combined on active business income eligible for the small business deduction (9% federal plus 2.2% Ontario) for days after 30 June 2026 (12.2% before that date; a straddling year is prorated by days) and 26.5% on general income (15% federal plus 11.5% Ontario).



**Are you based in Ottawa?**

No. EverStone works with Ottawa corporations entirely remotely. Documents move by secure upload and returns are e-signed, so there is nothing to attend in person.



**Does contracting mainly to federal departments create tax risk?**

The customer’s identity does not, but revenue concentration can. A corporation providing services that would otherwise resemble employment may be assessed as a personal services business, which turns on control, tools and independent business risk.

**What does a corporate tax return cost in Ottawa?**

Ottawa businesses pay the same published fees as everyone else. The T2 alone is priced after we review your enquiry, once the books have been reviewed. A one-owner trades corporation that adds bookkeeping, payroll and year-end statements typically pays $500 to $700 monthly for everything. [See the fee schedule](https://www.everstonecpa.com/pricing).

**Do you work with businesses outside Ottawa itself?**

Yes. Kanata, Nepean, Orléans and, across the river, Gatineau are served the same way as Ottawa, by video, phone, email and a secure upload link, on the same fixed fees.
