Accountant for incorporated Ottawa consultants

Reviewed by EverStone CPA · July 2026

Ottawa runs on contract work. A large share of the city’s incorporated owners are consultants on long institutional and government engagements — the exact profile the personal services business rules were written for. EverStone works with incorporated professionals and is an Ottawa small business accountant, at fixed fees, online.

Quick answer: If you are incorporated in Ottawa and most of your billing goes to one institutional client, the biggest number on your return is not a deduction — it is whether CRA could treat the corporation as a personal services business. That determination outweighs every expense claim combined. EverStone reviews it against your actual contracts and files the T2 at a fixed fee.

How EverStone CPA supports incorporated consultants in Ottawa — contract review, PSB risk and corporate tax

Why the Ottawa contract market concentrates risk

Long engagements with a single department or prime contractor are normal here, and they are also the fact pattern that raises personal services business risk. The test asks whether, without the corporation, you would reasonably be regarded as an employee of that client — judged on control, tools and workspace, chance of profit or loss, ability to substitute, and how integrated you are into their organisation.

Two further conditions have to hold: you (or someone related) must be a specified shareholder holding at least 10% of the corporation, and the corporation must employ no more than five full-time employees through the year. A one-person Ottawa consultancy meets both without trying. Our PSB guide covers the detail.

What a PSB determination actually costs

It is not a marginal adjustment. The corporation loses access to the small business deduction — the low rate you incorporated for — and loses the ability to deduct most ordinary business expenses, with deductions restricted largely to salary paid to you as the incorporated employee. An additional federal tax applies on that income on top of the general rate. Applied across several reviewed years, the outcome is usually worse than having been an employee throughout.

Contract terms are evidence, and most are written by the client

The engagement letter you sign was almost certainly drafted for the client’s convenience, not your tax position. Clauses on exclusivity, fixed hours, on-site presence and equipment supplied by the client all count against you if the arrangement is ever examined. Serving more than one client, using your own equipment, working to deliverables rather than assigned hours and carrying your own insurance all count in your favour. We read the contracts and tell you honestly where you sit — including when the answer is that restructuring is the right call.

Expenses, HST and the ordinary compliance year

Where PSB risk is not live, an Ottawa consultancy is a straightforward file: HST on fees, a home office where that is genuinely the base of operations, vehicle costs where there is real business travel, and a salary-and-dividend split recalculated annually rather than set once and forgotten. Where risk is live, the calculation changes, because salary to the incorporated employee is one of the few amounts that stays deductible.

If you think you may already be exposed

The worst version of a personal services business problem is the one discovered during a review of prior years, because by then the assessment covers every year in question and interest has been running throughout. If you read the test above and recognised your own arrangement, the useful thing is to establish the position now rather than wait to be asked.

There are usually three routes, and which fits depends on how clear-cut the facts are. The first is to change the substance of the relationship going forward — adding clients, using your own equipment, moving to deliverable-based terms — so that future years look materially different. The second is to accept the treatment and plan around it, because salary paid to the incorporated employee remains deductible even where the rules apply, which changes the whole salary-and-dividend calculation. The third, where past filings were wrong rather than merely arguable, is a correction through the CRA’s Voluntary Disclosures Program, which exists precisely for this and is far better used before contact than after.

We will tell you honestly which of the three your situation calls for, including when the answer is that the exposure is real and worth addressing rather than arguing.

Common questions

Ottawa accounting for independent consultants FAQ

I have one government client. Am I a personal services business?+
Possibly, and it is worth reviewing properly rather than assuming either way. One client is the strongest single indicator but is not conclusive on its own — the test looks at control, tools, chance of profit or loss, substitution and integration, plus whether you are a specified shareholder holding at least 10% and whether the corporation has more than five full-time employees. The cost of being wrong is high enough to justify a proper look.
What changes if CRA decides my corporation is a PSB?+
The corporation loses the small business deduction and the ability to deduct most ordinary business expenses — deductions are restricted largely to salary paid to you as the incorporated employee — and an additional federal tax applies to that income. Applied across several years under review, it is usually worse than if you had been an employee.
Does an on-site requirement in my contract hurt me?+
It is one factor among several, not a decision on its own. Working at the client’s site using the client’s equipment, to hours they set, points toward employment. Multiple clients, your own equipment, deliverable-based terms and your own insurance point the other way. What matters is the overall picture, which is why the contract is worth reviewing before it is signed rather than after.
Do you work with consultants across the Ottawa region?+
Yes — incorporated consultants and contractors in Ottawa, Kanata, Nepean, Orléans and the surrounding area, and across Canada. Everything runs online, which is usually the point when you are already spending your week on a client site.
