An Ontario software consultant bills $165,000 a year to one client. She works remotely, uses her own laptop for some tasks, joins the client’s daily development stand-up, and bills by the hour. Her contract has been renewed several times. She has no employees and reports her income on Form T2125. The agreement calls her an independent contractor, and she issues invoices with HST.
Is she necessarily self-employed? No. Nor do the daily meetings or single client necessarily make her an employee. The useful question is whether, in the actual engagement, she is carrying on a business on her own account. CRA’s guidance specifically for IT consultants treats several seemingly decisive facts—including one payer, team schedules and secure client equipment—as potentially neutral.
Can CRA challenge a sole proprietor’s status?
Yes. A person can report consulting income as business income and still be found to have worked as an employee under a particular engagement. The words independent contractor in the agreement, invoices, GST/HST registration, no T4, a business name, remote work and ownership of a laptop do not decide the issue individually. They have to be understood alongside the parties’ rights and what they actually do. A consultant can also be an employee under one engagement and self-employed under another. CRA: Information technology consultants; CRA: Employee or self-employed?.
This is a question of legal classification. It does not tell us how likely CRA is to examine a particular IT contractor. Public CRA material does not provide a reliable IT-specific reassessment probability, so a one-client arrangement should not be presented as an audit forecast.
What matters in an IT engagement?
Outside Quebec, the central common-law question is whether the consultant is in business on their own account. Control, tools, the ability to use others, financial risk, opportunity for profit, investment and management responsibility all help answer it; no single factor supplies a score. The Supreme Court described this whole-relationship approach in 671122 Ontario Ltd. v. Sagaz Industries Canada Inc., 2001 SCC 59. That case concerned a sales consultant and vicarious liability, so its facts are not an IT-contracting template. CRA’s IT-specific guidance shows how the factors can operate in technology work.
Direction versus coordination. A product owner may define acceptance criteria and require a security review without directing every step of the work. Daily stand-ups can be necessary to coordinate a release. The picture changes if a manager continually assigns new tasks, determines hours and leave, monitors how the consultant performs the work, and can move them between internal roles. Ask what the client has the right to direct, not just whether the client needs a deliverable.
Tools in context. A client laptop may be mandatory because production systems cannot be accessed from outside the client’s secure environment. CRA says that can be neutral. A personal laptop is similarly weak evidence if it represents the consultant’s entire investment. More useful questions concern who pays for software, training, insurance and other operating costs, and who chooses how to deploy those resources.
People and substitution. A genuine ability to hire help or send a suitably qualified substitute may show business independence. The right matters less if the client has effectively retained the named individual, security clearance makes substitution impossible, or the consultant could not actually delegate any work. Conversely, a security-based approval process does not by itself turn a business engagement into employment.
Profit, loss and management. Hourly billing is common on both sides of the line. Ask whether the consultant negotiates scope and rates, can reject work, incurs real costs, bears the cost of correcting defective work, or can improve profit through delivery decisions. A fixed fee can create risk, but a fixed-fee label without a genuine obligation to absorb overruns does little. The ability to pursue and service other clients is relevant, even if the consultant has only one at present.
Intention and actual practice. The agreement records what the parties intended, and its enforceable rights matter. If the contract promises an independent project business but the consultant instead fills an ongoing staff role under a manager, the practices need to be explained. The label cannot replace analysis of the relationship. CRA RC4110.
Does having one client make you an employee?
No. CRA’s IT guidance expressly lists providing services to one payer at a time among facts that can be neutral. A long engagement can also remain independent when it consists of distinct mandates and the consultant retains business control. Still, a long-running, nearly exclusive arrangement is worth reviewing: economic dependence can coexist with client control, limited substitution and little opportunity to profit beyond working more hours. The combined facts matter; there is no revenue-percentage rule that decides status. CRA: Information technology consultants.
Three arrangements that look similar on an invoice
Embedded developer. A consultant joins the client’s development team for successive renewals. The client sets hours, approves absences, assigns sprint work unrelated to a defined deliverable, and can redirect the consultant whenever staffing needs change. Those facts support an employment analysis more strongly than the consultant’s hourly invoice supports self-employment. A stand-up or client laptop alone would not lead to that conclusion.
Specialist with a defined mandate. A cloud architect agrees to migrate specified workloads, negotiates each phase and its fee, selects the technical method within the client’s security rules, may refuse additional projects, and pays to remedy work outside the agreed specification. The client supplies a secure machine and requires change-control meetings. Those controls can protect the client’s systems while the architect remains in business independently. Whether the risk and discretion are real must be checked against the contract and practice.
Consultant placed through an agency. First identify the contracts and payment flow: worker–agency, agency–end client, and who directs the work. The agency may itself employ the worker, or special CPP/EI rules may make a placement pensionable or insurable under particular conditions. The payer responsible for deductions can differ between CPP and EI and depend on who pays the worker. Do not assume that the end client is automatically the employer or that a T2125 filing settles CPP/EI treatment. CRA: Payments to placement and employment agency workers.
What could change after a finding of employment?
The consequences depend on which engagement and years are at issue, which statute is being applied, who paid the worker, and what has already been reported or remitted. A CPP/EI ruling is not itself a complete income-tax and GST/HST reassessment.
| Issue | Worker | Payer or client |
|---|---|---|
| Income tax | The receipts remain taxable, but may need to be reported as employment rather than T2125 business income. Tax already paid must be reconciled; the gross receipts are not simply taxed a second time. | If the payer is the employer, payroll income-tax withholding and reporting may need correction. In an agency arrangement, identify the actual responsible payer and applicable special rules. |
| Expenses | T2125 business deductions may be denied to the extent they relate to employment. Some employment expenses may still qualify, but under narrower rules and usually with a completed T2200. | The payer may have to correct slips and payroll records. |
| CPP or QPP | Self-employment contributions already paid need reconciliation against any employee contributions; a status change does not mean both full sets should simply remain charged. | An employer may owe the employer share and amounts it should have withheld, subject to the applicable assessment and recovery rules. |
| EI | Employment can be insurable where the statutory conditions are met; previous self-employed EI special-benefits participation, if any, needs separate review. | Employer and employee premiums may be assessed where employment is insurable. Agency placement rules can produce a different result from ordinary employment status. |
| GST/HST and, in Quebec, QST | Work supplied by an employee to an employer in the course of employment is not a taxable service in the ordinary contractor sense. Previously invoiced and remitted tax and claimed input tax credits or refunds require a transaction-by-transaction review. | The recipient may need to examine input tax credits or refunds previously claimed and any credit notes or corrected invoices. Cash already remitted cannot simply be ignored. |
The CRA employment-expense guide explains employee deduction conditions. The employee-service exclusion appears in the Excise Tax Act’s GST/HST definition of “service”; CRA’s section 232 guidance describes one mechanism for adjusting tax charged in error. The correct adjustment depends on invoices, filings, amounts remitted, input tax credits and statutory time limits. It is not safe to promise an automatic GST/HST refund.
Interest can arise on assessed amounts. Penalties depend on the particular provision and conduct; a classification dispute does not automatically establish gross negligence or another penalty. For most individuals, the normal income-tax reassessment period is three years from the original notice of assessment, with statutory exceptions, including qualifying misrepresentation or fraud. That period is not a universal deadline for CPP/EI, payroll or GST/HST matters. CRA: Income-tax reassessment periods. The actual years and deadlines must be checked separately.
Who decides, and how can a decision be challenged?
For an actual unincorporated engagement, the worker or payer may ask CRA for a CPP/EI ruling on status and whether the work is pensionable or insurable. Generally, a worker or payer must request it by June 29 of the following year. CRA may also examine payroll compliance and issue assessments. An income-tax assessment or GST/HST assessment follows its own process. A disagreement can be appealed; CRA says a CPP/EI ruling or payroll assessment generally has a 90-day appeal period, followed by a possible appeal to the Tax Court of Canada after the Minister’s decision. CRA: Request a ruling; CRA: CPP/EI appeals.
CRA makes administrative determinations and assessments; courts decide appealed disputes under the applicable law. A tax auditor’s description of a worker does not replace the statutory procedures or determine every tax consequence by itself.
Quebec: subordination is central
Quebec uses its civil-law framework. Under article 2085 of the Civil Code of Québec, employment involves work for remuneration under another person’s direction or control. Articles 2098–2099 describe a contract of enterprise or for services, including the provider’s freedom to choose the means of performing it without subordination to the client. CRA’s Quebec analysis asks whether there is a relationship of subordination and compares the parties’ stated intention with the actual arrangement. CRA RC4110, Quebec section; Revenu Québec: Determining your employment status.
For example, a Montreal cybersecurity consultant may have to work on client premises, use a locked-down device and join incident calls. Those facts may reflect security needs. More revealing is whether the client can direct the consultant’s methods, impose an internal work schedule and discipline, or move the consultant to unrelated staff duties. A consultant who instead undertakes a defined response mandate, controls the method within agreed security constraints and bears delivery risk presents different facts. Quebec’s subordination inquiry should be applied directly, not treated as a relabelled common-law checklist.
If an arrangement is employment, Quebec may also involve provincial source deductions and employer contributions, QPP and QPIP treatment, and a QST review in addition to federal issues. Which obligations apply depends on the workplace, payer and transaction; Revenu Québec’s source-deduction guidance is a starting point.
The Federal Court of Appeal’s decision in Wolf v. Canada, 2002 FCA 96 illustrates why the Quebec and agency facts need their own analysis. An aerospace engineer worked at a Quebec manufacturer through a placement firm; the Court concluded he was an independent contractor for the income-tax issue before it after considering the parties’ relationship under Quebec law. He was a highly skilled engineer, not a software developer, and the case involved a U.S. resident and historical tax years. It provides reasoning about subordination and a three-party arrangement, not a rule that every consultant placed by an agency is self-employed or exempt from CPP/EI.
Questions to ask about your own arrangement
Use these to gather facts, not to calculate a score:
- What work was actually promised: a defined result, or an ongoing role the client can continually redefine?
- Who can direct how the work is done, as distinct from setting security and acceptance requirements?
- Who sets working hours, approves absences and decides whether you can refuse new assignments?
- Could you serve another client during this engagement, and have you taken steps to find or serve other clients?
- Could another qualified person perform some or all of the work, and would you be responsible for that person’s pay and work?
- What costs do you bear, and what happens financially if work is late or must be corrected?
- Can better delivery decisions increase your profit, or does additional income depend only on more hours?
- Do successive renewals create distinct mandates, or has the role become part of the client’s ordinary staffing structure?
- If an agency is involved, who contracts with whom, who pays you, and who directs your work?
- Where do the contract’s promises differ from the way the engagement operates today?
No single answer determines status. Keep the agreement, statements of work, renewal history, invoices and records of how decisions and corrections are handled.
When a review makes sense
A review is useful when one engagement supplies most revenue for years, an agency or client asks you to incorporate, substantial T2125 expenses are being deducted, the working practices have drifted away from the agreement, or CRA or a payer raises status. The review should identify the relevant parties and years, examine both the contract and practice, and then consider the tax and payroll consequences that could actually follow.
