Incorporating a Professional Firm

A professional corporation allows professionals — such as doctors, dentists, lawyers and accountants — to provide their services to clients through a corporate entity, rather than personally. The corporate entity must be created under the auspices of provincial or territorial corporate statutes and comply with rules determined by provincial regulatory bodies. The rules typically control the structure and operation of such entities to ensure that they do not violate, or circumvent, professional codes of conduct and practice. For most professionals, the most compelling reason for incorporating is to benefit from corporate tax advantages. The principal advantage from a professional corporation is tax deferral. The difference between the tax payable by incorporated and unincorporated professional practices is significant. Individuals pay tax on their business income at progressive marginal tax rates.

For example, in 2016, the top combined federal/provincial marginal tax rate on ordinary income is about 47.7 per cent in B.C. for income that exceeds $220,000. In contrast, the combined federal and provincial corporate rate of tax is approximately 15 percent on the first $500,000 of professional business income and 26.5 per cent on income above $500,000.

The spread between personal and corporate tax rates allows professionals to defer tax if they leave their income in the corporation. Since business partners must share the $500,000 limit between themselves, the full benefits of incorporation accrue primarily to sole practitioners and small partnerships.

Tax deferral is a real and substantial tax saving, which can accumulate into very significant amounts, but only if the individual does not immediately require all of his or her earnings for personal use. The deferral stems from the ability of the shareholder to leave some of the after tax corporate earnings in the corporation. The magnitude of my deferral depends upon the reinvestment rate and the length of time that the corporate entity accumulates its after-tax income. Thus, professionals can use tax deferral as a surrogate pension plan.

Incorporation also enhances remuneration flexibility and allows the owner-manager to choose between receiving compensation as salary or dividends, which have very different tax consequences. For example, professionals may want sufficient salary income to allow them to contribute to a Registered Retirement Savings Plan (RRSP) and Canada Pension Plan (CPP). In other circumstances, an individual may prefer dividends if he has a cumulative net investment loss (CNIL) and wants to claim the capital gains exemption. The costs of administration may, however, outweigh the tax advantages if the professional needs to extract all of the professional corporation’s business income in each year.

Depending upon the applicable provincial legislation, professionals may be able to use a holding company to own the shares of a professional corporation and siphon off professional earnings to the holding company through tax free dividends. This will reduce shareholder risk in the professional corporation and allow the saved cash to accumulate in the Holdco. To be sure, there is no real risk in leaving surplus funds to be reinvested in the professional corporation itself if the professional shareholder is fully and adequately insured against negligence. A Holdco, however, adds greater certainty to the structure.

There are opportunities in some provinces to split income between family members, but such structures should take into account the attribution rules and the special “kiddie tax” on certain income that minors can earn from such structures. The kiddie tax can neutralize any benefits from splitting business income in corporations in which the parents participate actively. The shares of a professional corporation that qualifies as “small business corporation” may be eligible for the lifetime capital gains exemption when the shareholder disposes of his or her shares. In general terms, a small business corporation is a Canadian- controlled private corporation that uses all, or substantially all, of the fair market value of its assets in an active business in Canada. The exemption is worth $824,176 in 2016, and is indexed thereafter.

There are also some disadvantages of incorporating and operating through a professional corporation. For example: Expenses of incorporation;
• Annual maintenance of corporate entity;
• CRA payroll deductions and monthly remittances;
• HST registration and remittances; and
• Corporate accounting and tax returns

Professionals will need to evaluate their personal circumstances and income levels to determine if a professional corporation suits their business needs. Generally, the advantages should outweigh the incremental administrative, organizational and incidental costs associated with professional corporations. The key factor, however, is the amount of money the professional is able to leave in the corporation to accumulate without incurring the additional dividend tax upon extraction of the corporate funds
