Yes, you can legally operate both a sole proprietorship and a corporation at the same time in Canada, but doing so creates separate tax obligations, accounting complexity, and potential cash flow challenges that require careful planning. The CRA treats these as distinct entities, each with its own tax return, reporting requirements, and liability protection. However, mixing business activities between the two can trigger audits or reassessment if the CRA believes income is being improperly allocated between entities. Some Canadian business owners maintain a sole proprietorship alongside a corporation for specific reasons: - Testing new business lines: Running an experimental venture as a sole proprietor while keeping your established incorporated business separate. - Professional licensing: Certain regulated professions require sole proprietorship status for licensing purposes, while other work is incorporated. - Rental or passive income: Holding certain investments or properties as a sole proprietor while operating an active business corporation. - Gradual transition: Winding down an old sole proprietorship while ramping up a new corporation (though this should be temporary). - Spouse involvement: One spouse operates as a sole proprietor while the other runs the incorporated business, though this has specific income-splitting implications.
Yes, a corporation legally must have its own separate bank account. While a sole proprietorship can technically use your personal account, keeping it separate is highly recommended for accounting accuracy and to demonstrate to the CRA that the business is legitimate and distinct from your personal finances.
Not automatically, but operating both structures increases audit risk if the CRA suspects income is being improperly split between them or if the business activities appear identical. Clear documentation of why each entity exists and what work it performs is your best defense.
Yes, you can earn income from both sources, but each is reported separately on your tax return. Your sole proprietorship income goes on your personal return, and your corporation's income is reported through the T2 corporation return. You'll pay income tax on combined earnings at your marginal rate.
You'll file a final personal tax return including the sole proprietorship income up to the closure date. Any remaining business assets should be transferred carefully, as this may trigger deemed dispositions and capital gains. Consult a tax professional to ensure the wind-down is done correctly.
The Small Business Deduction only applies to active business income earned by a corporation on its first $500,000 of taxable income in Canada. Sole proprietorship income doesn't qualify for this deduction, which is one reason many active businesses incorporate. If both entities are related, CRA may apply aggregation rules that limit the deduction.
