The tax advantage is the main reason to incorporate
A sole proprietorship or partnership reports all business income on your personal return and you pay tax at your marginal rate, which in British Columbia can reach 53.5 percent on high income. A corporation pays corporate tax at roughly 11-13 percent on small business income (depending on whether you use the federal small business rate or BC’s rate). You then pay personal tax again when you extract money as salary or dividend, but the overall bite is smaller for many owners.
The exact saving depends on how much income you’re extracting and how you extract it. For some owners it’s $5,000-$10,000 yearly. For others it’s closer to $25,000-$30,000. This is the calculation your accountant should run before you decide.
Personal asset protection comes second
A corporation is a separate legal entity. If the business is sued or fails to pay a debt, the creditor sues the corporation, not you personally. As a sole proprietor, your personal assets—home, vehicle, savings—are at risk if the business is sued or can’t meet its obligations.
The strength of this protection depends on your industry and risk profile. A trades contractor doing high-risk work benefits more than a professional service provider with liability insurance. Still, every business faces unexpected claims.
The costs and compliance burden
Incorporation in British Columbia costs roughly $400-$500 in government fees and legal costs combined. Annual filing fees are $40 per year for a federal corporation or $135 for a BC provincial corporation. The real cost is in ongoing compliance: corporate year-ends, financial statements, and corporate tax returns all take more work than a personal return.
You’ll need a director (often you), possibly a corporate bank account separate from personal, and you must file within six months of year-end. Payroll, when you take a salary, must be remitted on schedule. All of this creates more moving parts.
The threshold where incorporation usually makes sense
If your net business income is below $40,000 per year, the tax saving often doesn’t cover the extra compliance cost. Between $40,000 and $70,000, it depends on other factors like whether you’ll reinvest earnings in the business or extract them all. Above $70,000-$80,000, incorporation is almost always worthwhile.
That threshold shifts if you’re already planning to retain earnings in the business to reinvest, to buy assets, or to save for lean seasons. Reinvested earnings taxed at corporate rates stay inside the company and grow more efficiently than earnings taxed at your personal rate.
The decision isn’t permanent
You can incorporate now and wind down later, or stay sole proprietor and incorporate when the numbers justify it. Some owners incorporate from day one for simplicity and the mental boundary between business and personal, even if the tax saving is small. Others wait until the math is clear.
Running the numbers takes about an hour, and it should be done with your accountant since the calculation is specific to your income level, extraction pattern, and province. If you’d like to explore whether incorporation makes sense for your business, we can walk through the math with you.
