Short answer: Incorporation can be useful when an IT contractor can retain meaningful funds after paying personal expenses, but the answer depends on business profit, province, contract facts, personal cash needs and the cost of running a corporation. There is no universal revenue threshold or guaranteed tax saving.
This guide explains what incorporation actually does, what it costs, and the specific factors that determine whether it makes sense for your situation.
What Incorporation Actually Does
Incorporation creates a separate legal entity. Your corporation earns income and pays corporate tax on it. You are generally taxed personally on salary or dividends paid to you. Other transfers, including shareholder loans, require their own tax analysis.
One potential advantage is tax deferral when a qualifying corporation retains after-tax business income. The amount depends on the applicable corporate and personal tax rules, the province, and how much the owner eventually withdraws. The corporation must also meet the conditions for the small business deduction; incorporation alone does not establish eligibility.
The deferral is not a permanent tax reduction. When you eventually withdraw corporate funds, you pay personal tax on the distribution. The benefit is timing.
What It Costs to Incorporate
Legal setup, government registrations, bookkeeping, corporate returns and any payroll or dividend reporting add cost. Fees vary with the province and the file’s complexity. Ask for a scope and fee estimate before comparing a corporation with the simpler sole-proprietor route.
How a Sole Proprietorship and Corporation Compare
| Question | Sole proprietorship | Corporation |
|---|---|---|
| Filing | Business income is reported on the owner’s personal return; GST/HST may also apply. | The corporation files its own return; the owner still files a personal return, with additional payroll or dividend reporting as applicable. |
| Paying the owner | Business cash can be drawn, while tax is based on business income. | Salary, dividends and shareholder transfers need distinct records and treatment. |
| Funds left in the business | Profit is taxed to the owner for the year, even if cash remains in a business account. | A qualifying corporation may retain after-tax funds, creating a possible deferral. |
| Ongoing cost | Generally fewer filings and corporate records. | Separate books, filings and corporate administration add cost. |
| Contract considerations | Review the actual working arrangement and client requirements. | Review the same arrangement, including personal services business risk. |
The sole proprietor versus corporation guide explains the broader comparison. If your immediate concern is how CRA could classify the work, the employment-status versus PSB guide separates the two legal questions.
Why Personal Cash Needs Change the Answer
The break-even calculation depends on how much income you leave inside the corporation. If you need all your corporate income for personal living expenses, there is nothing to defer.
Illustrative scenarios for review, not tax calculations: Assume two Ontario contractors each expect CAD $180,000 in annual revenue and CAD $20,000 in business expenses. Both would need to review their contract terms and eligibility for corporate tax treatment before drawing a conclusion.
- Contractor A expects to need about CAD $140,000 for personal spending and taxes. Little may remain in a corporation after withdrawals and corporate costs.
- Contractor B expects to need about CAD $70,000 for personal spending and taxes. More may remain in a corporation, so a detailed deferral and cost comparison could be worthwhile.
These figures do not calculate tax, prove that either contractor should incorporate, or account for every cash obligation. They show why equal revenue does not produce the same incorporation decision.
Consistency matters as much as the amount. Variable income complicates salary and dividend optimization because optimal compensation structures depend on predictable projections.
The Salary vs. Dividend Decision
Once incorporated, you need to decide how to pay yourself. Salary and dividends have different tax profiles.
Salary creates RRSP contribution room. Dividends do not. Salary results in CPP contributions, which creates a CPP benefit. Dividends do not trigger CPP. Salary is deductible to the corporation. Dividends are paid from after-tax corporate income.
The optimal mix depends on your RRSP room position, your need for CPP coverage, your province of residence, and whether your corporation is making enough profit to make a salary deduction meaningful.
There is no universal answer. The math needs to be run for your specific situation.
IT Contractor Considerations
An important risk is the personal services business rule. If the corporation meets the CRA’s listed conditions, the income may be treated as personal services business income, with material consequences for the small business deduction and available expenses. Review the facts of the client relationship before relying on a proposed corporate tax result.
Other contractor-specific considerations include U.S. client income, GST/HST treatment for export services, software and equipment costs, and whether corporate retained earnings are actually available after your personal cash needs.
What the Right Answer Depends On
Incorporation may make sense if:
- Projected profit exceeds the amount needed for personal expenses and corporate obligations
- You can retain funds for a useful period after considering costs
- Your contract facts have been reviewed for personal services business risk
- You are prepared for the additional administrative requirements
Incorporation may not make sense if:
- You need most of your income personally each year
- Your income is variable and hard to project
- The administrative cost exceeds the deferral benefit at your income level
- Your situation creates PSB risk that requires ongoing management
The incorporation decision depends on profit, personal withdrawals, PSB risk, province and administrative cost. A review should examine anticipated revenue and costs, personal cash needs, the proposed contract and any existing business structure.
