When one creates a business they are typically formed as a corporation, a sole proprietorship, or a partnership. What are the differences of each type of business structure, and which is best?
Sole proprietorship
Entrepreneurs starting a new business might operate as a sole proprietor. This is the simplest approach. The business needs to register its name and obtain a business number from the CRA. Of course when choosing a business name in any business form one should make sure the name is not confusingly similar to an existing name or trademark.
PROS | CONS |
Business losses can be deducted from other non-business income. | The individual is personally liable for business costs, losses and legal risks. |
Inexpensive to set up and maintain. | Doesn’t work for multiple owners. |
Not perceived as sophisticated. |
Partnership
A partnership is a business operated by more than one individual acting together — although the term is often misused in the legal sense. The Ontario Partnerships Act says “Partnership is the relation that subsists between persons carrying on a business in common with a view to profit…” The partners should sign a partnership agreement to document their arrangement. (This post describes a typical partnership, not limited liability partnerships that are available to some professionals.)
PROS | CONS |
Relatively easy to set up. | Each partner is personally liable for all partnership costs, losses, and legal risks — not just their ownership share. |
Corporation
Incorporation is the most common business structure. A business starting as a sole proprietorship might incorporate as soon as it makes money and can no longer offset losses against other income. A corporation is considered a legal entity that can own property and act just like a person. A corporation can have multiple owners who are shareholders, not partners.
PROS | CONS |
Liability is limited to the assets of the corporation, not the shareholders. | Can’t offset losses against other income when in startup mode. |
Perceived as sophisticated. | More expensive to set up and maintain. |
Tax advantages. |
Which business structure is best?
In most situations, a corporation is the best way to carry on a business. But other forms can have advantages depending on the situation.
