Personal tax accountant in Ottawa
Elsewhere, the province on a return is obvious. In the National Capital Region it can change, and it sets the provincial rates and credits for the whole year. See personal tax services and the Ottawa CPA page.
Quick answer: For a business owner in Ottawa, Ontario the provincial half of the personal return depends on where residence sits at the end of the year, not on where income was earned. Working across the Quebec boundary can change what has to be filed. EverStone prepares those returns remotely. A basic T1 starts at $125.
A personal return covers the T1 with slips such as the T4 and T5, RRSP and TFSA room, rental income on the T776 and business income on the T2125.

The province is fixed at the end of the year
Federal tax is the same wherever a Canadian resident lives. The provincial half follows residence at the end of the tax year, so one date governs a whole year of income. Living in Gatineau for eleven months and moving to Ottawa in December gives a very different result from the reverse, even with identical income and employer. People here cross the boundary routinely, so check before arranging a December move: the date has a measurable consequence.
Where you work does not decide who taxes you
The instinct is that income is taxed where it is earned. For provincial personal tax that is generally wrong: employment income is taxed by the province of residence at year end, not the province of the workplace. A resident of Ontario employed across the river is still filing as an Ontario resident. What can differ is what was withheld during the year, because withholding follows the employer’s establishment. A mismatch between where tax was withheld and where it is owed produces a balance due or a refund that has nothing to do with how much was earned.
Quebec administers its own personal tax
Quebec collects its own personal income tax through a separate provincial return. So in the National Capital Region, moving across the boundary can change how many returns are filed and with which agency, not just a schedule. Anyone moving either way should settle what that means for the year of the move before filing time, and anyone working on the other side should check how their withholding was allocated.
What it means for an incorporated owner
An owner’s corporation is taxed where it has a permanent establishment; the owner by residence at year end. The two tests are applied independently and can point to different provinces. Remuneration planning must use the combined personal rate that actually applies; assuming it follows the business location builds the plan on the wrong arithmetic. See working with an out-of-province CPA.
Federal benefits and the timing of a move
Several federal and provincial benefit programs use the address and province on file, and provincial credits differ substantially between Ontario and Quebec. A routine move can change entitlements as well as rates. Reporting an address change promptly keeps the right credits attached to the right year. See Ontario tax facts.

Remote, and there is no Ottawa office
EverStone has no Ottawa location. Engagements run entirely online — video meetings, e-signature and secure document upload, and the federal calculation is national legislation, so preparation is not tied to a local address. See remote personal tax in BC, Alberta, Ontario and Manitoba.

Who this is for, and who it is not
This suits an Ottawa filer whose year crossed a line of some kind: work or a business on the Quebec side, a move, self-employment, rental or investment income, or a corporation paying you. Someone with one Ontario T4 and nothing else can file with free software, and we will say so rather than quote. The rest is priced from the published fixed fees.
What happens when you get in touch
An Ottawa return moves through three steps, entirely remotely, with the fee agreed first.
- An email enquiry. We confirm where you lived on December 31, where the work was done, and what the CRA holds. You get the fee in writing.
- Federal slips retrieved. Our CRA authorization lets us pull the slips filed under your SIN. Any Quebec slips, and records the CRA lacks, come from you.
- Reviewed, then submitted. We go through the result with you before filing and explain what the residence rule meant for the provincial side.
