Considering incorporation

Incorporation is a structure decision, not a tax shortcut

Whether it makes sense depends on how much income will remain in the corporation after paying yourself, what PSB risk looks like in the new structure, and whether the added compliance is proportionate to the benefit at your income level.

Get in Touch Key factors

Common situations

Most contractors who are weighing incorporation arrive with one of these as the starting point.

  • Contract income is high enough that a portion is left unspent after covering personal expenses
  • Currently filing as a sole proprietor and asking whether the structure still makes sense after one or two years
  • A new long-term contract is starting and the agency or client is asking for a corporation
  • Heard about salary and dividend planning but unsure whether it applies at your income level
  • Concerned about PSB risk and wondering whether a corporation provides protection
  • Not sure whether to incorporate federally or provincially, or which province makes sense

What the decision actually depends on

Incorporation is not a yes or no question. It is a set of factors that interact with each other and with your specific contract and income situation.

  • Retained earnings threshold

    The core question is whether meaningful income will remain in the corporation after paying yourself enough to cover personal expenses. That remainder is the retained earnings. The tax deferral benefit of incorporation depends on having earnings to retain. At lower income levels, the structure may add complexity without a proportionate benefit.

  • Small business deduction

    Canadian-controlled private corporations (CCPCs) pay a reduced federal rate on the first $500,000 of active business income through the small business deduction. The combined federal and provincial rate varies by province. The deferral benefit exists because corporate rates are lower than personal marginal rates, but only until the money is paid out.

  • PSB risk after incorporation

    Incorporation does not eliminate personal services business risk. If your corporation provides services through a staffing agency to a single client and the facts suggest an employer-employee relationship, CRA can still apply PSB rules to the corporation. The structure of the arrangement matters more than the legal form.

  • Fiscal year election

    A corporation can choose any fiscal year-end other than a calendar year. The election is made with the first T2 filing. The wrong fiscal year can create timing mismatches between corporate income and personal draws. The right election depends on contract start date, income timing, and planning preferences.

  • Province of incorporation

    Most IT contractors incorporate provincially in their home province, which is simpler and cheaper to maintain than federal incorporation. Federal incorporation is useful if you operate across multiple provinces or want name protection nationally. Either route requires registration in the province where you operate.

  • Transition from sole proprietorship

    Incorporating mid-year creates two tax periods: the sole proprietorship period and the corporate period. The timing matters for GST/HST registration, final T2125 reporting, bookkeeping continuity, and instalment obligations. Starting a corporation at the beginning of a new contract is usually simpler than converting mid-file.

The federal corporate tax rate for CCPCs on income eligible for the small business deduction is published by CRA at canada.ca/corporation-tax-rates. Federal incorporation is available through Corporations Canada. Provincial incorporation in Ontario is handled through the Ontario Business Registry.

What Teplov CPA handles

Three areas that need to be reviewed before and after the incorporation decision: whether to incorporate, how to set up the new entity, and how to manage the transition.

01 · Timing

Incorporation timing analysis

  • Retained earnings projection at your current contract rate
  • Sole proprietor vs. corporation tax comparison
  • Income threshold review for when incorporation makes financial sense
  • Provincial vs. federal incorporation assessment
  • PSB risk review of the proposed arrangement
02 · Setup

Pre-incorporation setup

  • Fiscal year election planning
  • GST/HST registration for the new corporation
  • Chart of accounts structured for contractor income and owner draws
  • Salary and dividend structure design
  • Shareholder loan account setup
03 · Transition

Transition planning

  • Timing the incorporation around contract start or fiscal year
  • Closing out sole proprietorship records and final T2125
  • First T2 corporate return preparation
  • Instalment obligation review for both periods
  • CRA business number and payroll account registration

The retained earnings question

The tax deferral benefit of a corporation exists because the corporate rate on active business income is lower than the personal marginal rate at higher income levels. The corporation pays less tax on the income in the year it is earned. The remaining amount stays in the corporation until it is paid out as salary or dividends.

The benefit compounds over time when retained earnings are reinvested or left in the corporation for years. But if all corporate income needs to be paid out to cover personal expenses, there are no retained earnings to defer. The structure adds T2 filings, payroll accounts, GST/HST for a new entity, and shareholder loan tracking without a proportionate tax advantage.

The right question is not whether incorporation saves tax in theory. It is whether your income level and personal spending leave enough in the corporation to make the deferral meaningful at this stage of your contracting career.

Common questions

Q.01 When does incorporation actually make financial sense for an IT contractor?
The most common threshold cited is $100,000 or more in annual contract income, but the real question is how much income will remain in the corporation after paying yourself. If your personal expenses require most of your contract income, the retained earnings available for deferral are limited and the added complexity may outweigh the benefit. The analysis depends on your income level, province, personal expenses, and contract stability.
Q.02 Does incorporating protect me from PSB risk?
No. Incorporating creates a corporation, but the PSB rules apply to corporations that provide personal services through a staffing agency or directly to a client where the facts suggest an employee-like relationship. CRA looks at the working arrangement, not the legal structure. A sole proprietor and an incorporated contractor can both face PSB scrutiny if the facts support it.
Q.03 Should I incorporate federally or provincially?
Most IT contractors incorporate provincially in their home province. Provincial incorporation is less expensive to set up and maintain, and is sufficient for contractors who work in one province. Federal incorporation under the Canada Business Corporations Act offers national name protection and is useful if you operate across multiple provinces. Either route requires extra-provincial registration in any province where you carry on business.
Q.04 What is the small business deduction?
The small business deduction reduces the federal corporate tax rate for Canadian-controlled private corporations on the first $500,000 of active business income each year. The reduced combined federal and provincial rate is significantly lower than personal marginal rates at higher income levels. The deferral benefit exists because corporate tax is paid at the lower rate, but the personal tax is deferred, not eliminated. It applies when retained earnings are eventually paid out.
Q.05 Can I incorporate mid-year?
Yes, but mid-year incorporation creates two separate tax periods: the sole proprietorship period reported on T2125, and the corporate period reported on a T2. The transition requires careful bookkeeping to separate the two periods, coordinate GST/HST registrations, and avoid double-counting income. Starting a corporation at the beginning of a new contract or calendar year is typically simpler.
Q.06 How do I pay myself from a corporation?
The two primary methods are salary and dividends. Salary creates earned income for RRSP contribution room and is deductible to the corporation. Dividends are paid from after-tax corporate income and taxed personally at dividend rates. Most incorporated contractors use a combination of both, and the optimal mix depends on personal income needs, provincial rates, RRSP room, and the corporate tax position for the year.
