Other decision factors
The decision also depends on liability, personal guarantees, administration costs and your time horizon. Family income splitting and sale exemptions have conditions: neither benefit is assumed here. This comparison does not automatically recommend a legal structure.
Method and sources
The sole proprietor pays personal tax on all profit, then contributions and personal needs. The company deducts additional costs, pays corporate tax and distributes the smallest gross dividend meeting the same net need. Remaining cash stays in the company; a future withdrawal then applies your assumed tax.
