When incorporating is worth it, and when it is not

Current to September 11, 2026.

Incorporation is often treated as a milestone. It is a tool, and like any tool it suits some situations and not others.

What incorporating gives you

• A separate legal person that can contract, hold assets and carry liability in its own name
• Limited liability, subject to real exceptions such as personal guarantees and certain director obligations
• Access to corporate tax treatment, including the small business deduction, a reduced rate on the first tranche of active business income where the corporation qualifies for it
• A structure that can accommodate more than one owner, and one that can be sold

What it costs

Set-up, an annual return, a corporate tax return, and the discipline of keeping the corporate record current. None of these is large individually. Together they are a standing obligation that a sole proprietorship does not carry.

When it is usually worth it

• Where the business carries genuine liability exposure
• Where profit exceeds what the owner needs to draw, so that deferral has value
• Where there is more than one owner, or will be
• Where a client, lender or insurer expects it
• Where the intention is eventually to sell

When it usually is not, yet

Where the business is small, the profit is being fully drawn, the liability is modest and there is one owner. In that position the compliance cost frequently exceeds the benefit, and the honest answer is to wait.

The part people get wrong

A single-client consulting corporation is the arrangement most worth revisiting, because the tax advantage assumed at the outset may not survive the personal services business rules. See what a personal services business is.

Where there will be more than one owner, the decision to incorporate and the decision about what the owners have agreed between them are best taken together, not two years apart. And if a sale is a realistic destination, the conditions for the capital gains exemption are easier to build in at the start than to retrofit. See business.
