Selecting Your Business Structure – Sole Proprietorships, Corporations, Partnerships – Which is Right for You? – Part II

Selecting Your Business Structure Part 2

In part I we discussed the major advantages and disadvantages of operating your business through a sole proprietorship. In this article, we discuss the major benefits and drawbacks of operating your business through a different business structure – a corporation.


 A corporation is the most common form of business organization. A corporation is a registered separate legal entity. A corporation can be operated by one or more persons. A corporation has its own tax obligations and must file its own income tax return called a T2 return. A corporation has various tax benefits, continues in perpetuity and shields the liability of its officers, directors and shareholders from the liability of the corporation.

 Separate Legal Entity, Limiting Liability of Owners

 A corporation is a legal entity separate in law from its owners and can own property, carry on business, possess rights, and incur liabilities. Although the shareholders own the corporation through their ownership of shares, they do not own the property belonging to the corporation, and the rights and liabilities of the corporation are not the rights and liabilities of the shareholders.

If a business venture involves a great deal of risk, it is preferable to incorporate the business so as to isolate and protect the owner’s personal assets from corporate creditors and/or lawsuits. Sole proprietors are liable to the full extent of their personal assets for the liabilities of their businesses, whereas a shareholder’s liability to creditors of the corporation is limited to the amount of the shareholder’s investment. Director’s are not liable at all (except where the Director engages in fraud).

 Multiple Owners and Ease of Change of Ownership

 Incorporations can potentially have an unlimited number of different owners. If the business has or is planning on having a number of owners, incorporation is preferable. It is also easier to transfer ownership in the business, as all the owners may simply sell their shares to another shareholder or sell them back to the Corporation. It is also easier to pass on the business to one’s next generation.

Perpetual Existence

 Because corporations are distinct legal entities they enjoy perpetual existence. Partnerships and proprietorships cease to exist upon the death of a partner or the owner of a business. This can lead to undue hardship on the business at the time of death and the extreme difficulty of transferring the business to one’s next generation. In distinction, a corporation has a continual life of its own in spite of a death of shareholder/director of the incorporation. Therefore, substantial estate planning benefits result from this aspect of incorporation.

Tax Benefits

Although the foregoing considerations are significant when determining which form of carrying on business to select, unquestionably the most important and often the determining factor will be the impact of income tax on the business structure.

The income or loss of a business carried on by a corporation is both subject to tax at the level of the corporation, and the income is taxed again at the shareholder level once dividends are issued to the shareholders (owners) themselves.

Although this may seem like double taxation, less tax is still paid when the income is earned through a corporation. This occurs predominantly where the business is a Canadian Controlled Private Corporation (known as a CCPC  and defined    in s. 125(7) of the ITA) that earns Active Business Income (ABI) qualifying for the Small Business  Deduction (SBD).

A CCPC in Ontario is taxed at 13.5% on the first $500,000 of ABI in each year, which is 24.5% less than the combined average marginal personal tax rate. By way of comparison, an individual proprietor in Ontario is taxed at a top marginal tax rate of 37.91% (combined federal and provincial rate) on income in excess of $87,559. By way of another example, an individual’s income is taxed at a top marginal tax rate of 46.41% (combined federal and provincial rate) on income in excess of $142,353.

Business Structure

A corporation is thus taxed at a significantly lower tax rate than the individual is taxed earning income as a sole proprietor. Incorporation allows the individual to pay taxes only on the amount he dividends out of the corporation to himself (essentially, his income), while the retained earnings, or the ‘savings’ can remain in the corporation for future use, tax neutral.

Further, if all income earned by the corporation is paid out in the form of salary, the corporation will pay no income tax. The shareholders will be taxed at the same rate as if they had earned the income through a sole proprietorship or a partnership.

Finally, an added benefit of operating your business through a corporation is that you may take advantage of the Lifetime Capital Gains Exemption (LCGE) which allows you to shelter $848,252 from taxes over the course of your lifetime by selling the shares of the corporation. For more information on the LCGE and how you may take advantage of this excellent tax planning tool, read our article What is the Lifetime Capital Gains Exemption and How Can I Take Advantage of it?
