Business Structures

A major consideration when establishing or managing a small business is choosing which legal structure to operate your business under. There are basically three main choices; Sole Proprietorship, Partnership, and Incorporation. These are quite distinct structures with particular advantages and disadvantages depending on the situation. Here is a brief overview:

Sole Proprietorship

This is by far the simplest legal structure to adopt and is often chosen by individuals who are just starting out in business. Legally, and from a tax perspective, the business is not separate from the individual. A Sole Proprietor does not file a separate tax return for the business but rather includes any business activities in their own regular return. The pros and cons of this structure are:


  • Very simple to establish. Except where the name of the company is different from the owner/operator’s name, no legal registration is generally required.
  • Easy to adjust the workings of the operation with few legal constraints
  • Simple to cease operations if required
  • No need to share profits
  • The ability to use business losses against other personal income


  • Limited ability to access additional financing. Since the business is not separate from the owner, any new financing will be determined by the owner’s creditworthiness
  • The entire business management burden will typically fall on the owner
  • Business continuation – the business ceases on the death or retirement of the owner
  • Unlimited legal liability – any legal action taken against the operation is also taken directly against the owner, which can result in material claims on the owner’s assets

A Partnership exists where two or more people engage in a profit seeking enterprise. A Partnership is an interesting arrangement where the Partnership itself is viewed as a separate entity on a certain level but each Partner has a legal and fiduciary responsibility to the other Partner(s). Partnerships are often established where two or more people combine their resources and skills to achieve a common goal. A Partnership can be established simply by the concerted actions of two or more individuals but, it is highly recommended to draft and institute a formal Partnership Agreement that details issues such as amount of time or resources contributed, responsibilities, how profits (losses) are shared, and admittance of new partners. From a tax perspective, annual income or losses are determined at the partnership level and then allocated to the Partners according to the Partnership Arrangement. The pros and cons of this structure are:


  • Relatively simple to establish and operate
  • Flexibility in operation (at least with few partners involved)
  • Partners will receive their pro rata share of any losses, which can be used against personal income. This can be advantageous in the early years of an operation where losses are expected.


  • Due to the nature of a Partnership, the death or departure of a Partner will cause the Partnership to cease. However, this issue can be addressed through a properly structured Partnership Agreement.
  • The major shortcoming of a Partnership is the unlimited liability of the Partners. In an ordinary general Partnership each Partner will be personally liable for the actions of the other Partners.

A Corporation is a distinct legal entity that has a legal existence and files tax returns separate and apart from the actual owners of the business. A Corporation is established under either provincial or federal legislation. The owner or owners of a Corporation are shareholders. While you are certainly familiar with ‘Public’ corporations whose shares trade on a stock exchange, the great majority of Corporations are “Private’ and owned by one or a few shareholders. As a separate legal entity a Corporation must be registered under the appropriate provincial or federal legislation. Depending on the particular situation, there can be material tax advantage by operating under a corporate structure, a key reason why this arrangement is often chosen. The pros and cons of Incorporation are:


  • Limited Liability of shareholders – as a separate legal entity, a Corporation can be sued and the shareholders are only liable to the extent of their investment in the Corporation so that their personal assets are not at risk.

    Important Note – It is important to appreciate that although corporate law extends limited liability to shareholders, potential creditors of corporations (particularly new and/or small corporations) will typically require personal guarantees from shareholders before extending credit.

  • Business Continuity – as a separate legal entity, a Corporation has an existence separate from that of the shareholders, which typically makes the transfer of shares to other interested parties fairly straightforward.
  • Tax Considerations – he corporate structure provides two main potential tax advantages: usually a small Corporation will be eligible for the Small business deduction. The small business deduction will increase to 18% effective January 1, 2018, and to 19% effective January 1, 2019, resulting in small business tax rates of 10% and 9%.


  • Corporations are subject to much more legislation – both federal and provincial, compared to other business structures. This can result in the expenditure of time and money.
  • Corporate losses cannot be passed on to be used by shareholders personally.

Which Structure is ‘Best?’

This is a question that can only be properly answered after reviewing and analyzing a particular situation, but a few rules of thumb can be offered:


This typically makes sense when a person is starting out in business, does not need a lot of capital and wants to keep establishment costs low. As well, any expected losses while the company becomes established can be assumed by the owner/manager personally for tax purposes.


If two or several like-minded people have a business goal and can agree on the relative contributions, this may be appropriate. Any expected losses of the partnership can be assumed personally by the Partners. Unlimited liability will exist but in many jurisdictions; the ‘Limited Liability Partnership’ for professionals such as lawyers and doctors will serve to reduce this.


Generally when a company has become established and expects to be able to generate profits and secure financing, the tax advantages and limited liability of Incorporation are very attractive.
