Business structure comparison
QuestionSole proprietorCorporation
Setup and ongoing costRegistration/licence requirements depend on your location and business name. Often less administration.Incorporation, annual corporate filings and professional/accounting costs; actual fees vary.
Tax returnGenerally personal T1 with T2125 business reporting.A separate T2 corporate return, plus personal reporting for amounts paid to you.
Tax structureNet business income enters your personal tax calculation, whether or not withdrawn.Corporate tax and salary/dividend choices interact. Retaining profit may defer personal tax, but incorporation does not guarantee a total tax saving.
Legal identity and liabilityYou and the business are not separate legal persons; personal assets can be exposed.A separate entity with limited liability; personal guarantees, director obligations and other exceptions still matter.
Record keepingKeep business records and business/personal allocations clearly documented.Maintain separate corporate books and document shareholder transactions, payroll/dividends and statutory records.
When to discuss itA straightforward business operated by one person may suit this structure; assess commercial and personal risks.Discuss growth, retained profits, partners, client requirements and risk with an accountant and lawyer; there is no universal income cutoff.
