Ottawa Accountant for Government Contractors, Tech & Consultants

Reviewed by EverStone CPA · July 2026

EverStone CPA helps Ottawa’s incorporated consultants, tech founders and government contractors with corporate tax, bookkeeping and advice — delivered securely online by a dedicated CPA, at a fixed, up-front fee.

Who we help here: IT and management consultants working federal contracts, SaaS and tech founders, and professional-services corporations billing through staffing agencies — owners whose biggest tax risk usually isn’t HST, it’s how CRA views the contract itself.

Quick answer: A large share of Ottawa’s incorporated owners are consultants billing government and institutional clients. EverStone handles that structure — corporate tax, HST, and a proper look at personal services business risk — entirely online from BC, at a fixed fee agreed before work begins.

Why EverStone

A CPA who understands what a federal-contract structure actually risks

Ottawa has an unusually high concentration of incorporated consultants who bill primarily to one federal department, agency or prime contractor — a completely normal way to build a business, but one CRA scrutinizes closely. We handle your T2 and Ontario HST, and just as importantly, we look at how your contract is structured so it continues to hold up as an independent business relationship, not just a paycheque with extra paperwork.

In Ottawa you work directly with a Chartered Professional Accountant who tracks your file year-round, not just at tax time. Everything is online with video and phone meetings, and the fee is fixed and quoted before any work begins.

Ontario tax, from a contractor’s perspective

What Ontario’s HST means for an Ottawa consulting business

One combined tax is simple to file — the harder question is whether CRA sees your income as business income at all.

One tax, not two

Ontario’s 13% HST combines federal and provincial sales tax into a single return and one set of input tax credits — simpler to file than a two-tax province, provided your invoicing correctly reflects what a contract-based consulting business can actually claim.

Corporate tax rate

Ontario taxes active small-business income at 3.2% provincially, on top of the 9% federal small-business rate — a rate that only applies if CRA agrees your income genuinely qualifies as active business income from an independent corporation.

Employer Health Tax

Employer Health Tax applies once an Ottawa employer’s payroll passes Ontario’s exemption threshold — relevant for consultancies that start subcontracting to other consultants or bringing on staff as a contract grows.

What EverStone CPA handles for Ottawa businesses — corporate tax, personal tax, bookkeeping, GST/PST, payroll and advisory

Corporate Tax (T2)

T2 returns and year-end statements for Ottawa’s government contractors, IT consultants and professional-services corporations, with HST and CRA correspondence handled as part of the file.

Personal Tax (T1)

Personal and self-employed T1 returns for Ottawa owners, planned around contract income and a salary-and-dividend mix that holds up to scrutiny.

Bookkeeping & Payroll

Monthly bookkeeping and payroll for Ottawa firms, kept current and ready whenever a contract renewal, security clearance review or CRA request needs documentation.

GST / HST

Ontario HST registered and filed on schedule, reconciled cleanly against contract invoicing and subcontractor payments each period.

Business Advisory

Direct advice on contract structure, rates and incorporation decisions for Ottawa consultants, from a CPA who understands government-contracting risk.

Fractional CFO

Part-time CFO support for growing Ottawa practices that need budgeting, forecasting and financing guidance beyond basic bookkeeping.

Ottawa’s government-contracting & tech economy

Built for consultants who bill mostly one client

Ottawa’s economy is unusually concentrated around federal government contracting, technology and professional services — and a large share of that work flows through incorporated consultants who bill primarily to one department, one prime contractor, or one staffing agency for extended stretches. That pattern is completely normal, but it puts these businesses closer than most to CRA’s personal-services-business test, and it means contract structure and invoicing matter as much as the numbers themselves.

We handle T2, HST, payroll and year-end statements, and we review how your engagements are structured — control, tools, financial risk, integration into the client’s operations — so your corporation continues to function like an independent business rather than an employment relationship with extra paperwork.

The issue we see most often

Personal-services-business risk for Ottawa’s federal contractors

The single biggest tax issue we see in Ottawa isn’t HST or the corporate rate — it’s whether CRA will accept that a consultant working through a corporation, for one federal department or one prime contractor, is genuinely running an independent business rather than functioning as an employee with a corporate wrapper. CRA calls this a personal services business, and Ottawa’s concentration of long-term, single-client government and staffing-agency contracts makes it one of the most exposed markets in the country for this exact issue.

The consequences are significant. A corporation reassessed as a personal services business loses access to the small-business tax rate, loses most of the expense deductions an ordinary corporation can claim, and ends up taxed close to the top personal rate on that income — while the owner still carries all the cost and complexity of running a corporation, with none of the tax advantage that was presumably the point of incorporating in the first place.

CRA weighs a handful of practical factors: whether the client controls how, when and where the work is done; whether you supply your own equipment and tools rather than using the client’s; whether you carry meaningful financial risk on the engagement, such as fixed-price billing rather than hourly time tracking; and how integrated you are into the client’s internal reporting structure and day-to-day operations. None of these are decided by what your contract says on paper — CRA looks at how the relationship actually functions.

For Ottawa consultants and IT contractors working long federal or staffing-agency engagements, we review the arrangement against these factors early, flag where the structure is exposed, and where possible help you document and diversify the relationship so the corporation holds up as a genuinely independent business — before a CRA review makes that determination for you.

Contract structure is the evidence, not the label

Ottawa consultants often assume the wording of a statement of work settles their status. It does not. Where a corporation provides one person’s services to a single client on a long engagement, what matters is how the relationship actually operates: who directs the work, whose equipment and systems are used, whether there is any real chance of profit or risk of loss, and how integrated the consultant is into the client’s organisation.

For public-sector and government engagements that assessment has a practical wrinkle. Security clearance, mandated tools, on-site presence and fixed reporting lines are often contractual requirements rather than choices — but to an outside reviewer they can read as markers of control. That is not fatal, and it does not mean the arrangement is wrong. It means the file needs to show why those terms exist and what genuinely remains within your discretion. The time to capture that is when the contract is signed, while the reasoning is fresh and the documents are to hand — not two years later under review, reconstructing intent from memory.

Practically, that means keeping the statement of work, any subcontracting or substitution rights, evidence of other client relationships, and records of your own equipment and overhead in one organised place. We set that structure up at onboarding so it accumulates as a by-product of normal bookkeeping.

Ottawa industries we work with most

Ottawa’s owner-managed economy leans heavily on independent consultants, IT and engineering contractors, and professional services firms working to institutional and government contracts. That produces a distinctive tax profile: long single-client engagements, contract structures written by the client rather than the contractor, and income that is stable but concentrated. Concentration is exactly what raises personal services business risk, and it is the first thing worth reviewing for an incorporated Ottawa consultant. Independent consultants on institutional and government contracts are the largest group we work with here — see accounting for Ottawa consultants. Realtors and personal real estate corporations sit outside that consulting profile — see realtor accounting in Ottawa.

Where a client is based often says a lot about the contract they hold. Kanata is the tech corridor — incorporated software and engineering contractors, frequently billing one prime for years at a time. Nepean and Stittsville carry more trades, construction and local professional practices. Barrhaven and Orléans are heavily residential and produce independent consultants and contractors working from home offices rather than premises. We work with all of them online rather than in person, so none of it depends on being nearby.

How working with a Ottawa business actually runs

Everything is remote, and deliberately so: you get a CPA who replies, not one who is close by. A first consultation runs by video or phone. Documents move through a secure upload rather than a courier or a drop-in, and signatures are electronic. Through the year you can call or email with a question without a bill following it, because the fee is fixed and agreed before any work begins — which is the point, since the questions worth asking usually arrive before a decision, not after. The same CPA handles your file from start to finish, so the person who prepares your return is the person who answers the phone. For Ottawa owners that removes the two things that make an accountant hard to use: travel, and the hesitation to ask.

What a Ottawa client’s year looks like

For most Ottawa clients the year runs on the contract cycle rather than the season. We keep books current, review the client mix and contract terms while there is still time to change them, and plan the salary-and-dividend split against actual income rather than a default. HST files on its own frequency. The corporate return and the balance owing follow the fiscal year-end, and the balance is due before the return itself — the deadline owners most often miss.

Common questions

Questions from Ottawa contractors and consultants

Can an accountant outside Ottawa file my corporate taxes?+
Yes. Where your CPA sits has no bearing on it — the T2, T1, GST/HST and payroll returns are all federal, and Ontario corporate tax is collected with the federal return rather than filed separately.
How do we exchange documents securely?+
Through a secure client portal. For consultants billing government and public-sector clients this matters more than usual: contracts, statements of work and invoicing records are the evidence behind your worker-status position, so they are kept in one organised place rather than scattered across email. Approvals are by e-signature.
Do you understand Ontario tax rules?+
Yes. The Ontario piece is straightforward — corporate tax is administered with the federal return, so a single T2 covers both. The piece that actually needs attention in Ottawa is worker status on long public-sector contracts, and whether the way a contract is structured supports the position you are taking.
Does it matter that my accountant isn’t physically in Ottawa?+
No — corporate tax, HST and CRA filings are federal and provincial matters handled the same way regardless of your accountant’s location. We work with Ottawa clients entirely online, by video and phone, with documents moving by secure email and e-signature.
I bill almost entirely to one federal department through a staffing agency — is that a problem?+
It can be, if CRA determines the arrangement functions like employment rather than an independent business — this is a personal services business reassessment, and it’s a real risk for Ottawa’s contract-based government consultants. We review your engagement against CRA’s control, tools, risk and integration factors.
What happens if my corporation is reassessed as a personal services business?+
You lose access to the small-business tax rate and most standard corporate deductions, and the income is taxed at a rate close to the top personal rate — while you still carry the cost of running a corporation. We review your contract structure specifically to avoid this outcome.
How does Ontario’s HST work for a consulting business specifically?+
Ontario combines GST and PST into a single 13% HST, so you file one return with one set of input tax credits — simpler than a two-tax province, provided your invoicing and contract billing are structured correctly.
How much does an accountant cost for an Ottawa business?+
Fees are fixed and confirmed before any work begins, quoted after a free consultation. Corporate tax returns and year-end financial statements are quoted individually after a free consult. Bookkeeping starts at $300/month and personal tax from $100, all quoted to your situation.
Does working with a BC accountant from Ottawa create scheduling problems?+
Rarely. We are on Pacific time, three hours behind Ottawa, so our workday overlaps your afternoon and anything you send late in your day is typically dealt with before your next morning. Consultation times are shown in Eastern time automatically when you book, so there is nothing to convert. Federal filings and CRA deadlines are identical wherever your accountant is based.

For the year end itself, Ottawa financial statements covers unbilled time, revenue concentration and personal services business exposure.

How it works remotely

Working with a virtual accountant in Ottawa

Ottawa’s incorporated-consultant economy has one accounting characteristic that shapes everything else: a large share of owners bill a small number of clients, sometimes only one, often on long government or public-sector contracts. That pattern is exactly what the personal services business rules examine, and it is the first thing worth reviewing properly rather than discovering at year-end. The rest of the engagement runs online end to end — secure document exchange, video meetings scheduled around contract work, e-signature approvals. Ontario corporate tax is administered with the federal return, so there is no separate provincial filing to coordinate, and HST on consulting fees follows the place-of-supply rules rather than where your desk happens to be.
