Business owners have a few options when choosing the legal structure for providing goods and services – most commonly sole proprietorships, partnerships and corporations.
Of those, a corporation is clearly distinguished as a separate legal entity from those who own and operate it. This opens the door to potential tax advantages, enhanced creditor protection, extended business continuity and sharing of ownership. However, not every business is entitled to unbridled use of a corporation, particularly in the case of professional services.
The availability and constraints placed on “professional corporations” varies from one profession to another and across provinces. Navigating the rules can be challenging, but doing so will allow a professional to make an optimal decision on how to best structure a practice. This article outlines the key issues that are explored in greater depth in our Tax & Estate InfoPage titled Professional corporations.
Corporations, liability and malpractice
To repeat, a corporation is a separate legal entity from its owner/shareholders. To the extent that shareholders have not given guarantees, their personal exposure is generally capped at – or “limited” – to losing their initial investment.
This characteristic is also true of professional corporations in general business dealings, but there is no shield against malpractice claims. The professional remains personally responsible for the professional services and advice given, for which appropriate liability insurance is invariably required as a condition of the licence to practice.
Tax aspects of incorporation
Our tax system is set up so that roughly the same amount of tax is paid whether income is earned personally or through a corporation then paid as a dividend to a shareholder. The accompanying table illustrates how this integration of corporate and personal taxation works.*
Professional income earned personally
- Income $1,000
- Personal tax (45%) ($450)
- After-tax cash $550
Professional income earned by corporation
- Income (A) $1,000
- Corporate tax (15.3%) (B) ($153)
- Net income $847
- Dividend to shareholder $847
- Gross-up (18% rate) $153
- Taxable dividend $1,000
- Personal tax (45%) ($450)
- Dividend tax credit $153
- Net personal tax (C) ($297)
- After-tax cash (A – B – C $550
* Model tax rates are used for illustration purposes and rounded for ease of display. Actual rates will vary by province, but there is no material difference in the comparative after-tax cash, being on average less than a quarter of a percentage point across the provinces.
Still, the use of a corporation may enable both tax savings and tax deferral.
Simply put, tax savings arise where the rate of tax is lower than would otherwise apply. Personal tax rates for an unincorporated professional may be 50% or more depending on province, whereas the corporate small business tax rate ranges from 11% to 19%. Comparatively, a corporation will usually have significantly more to reinvest in building the business than will an unincorporated professional.
Tax deferral is the ability to push taxation to a later point in time. If the professional does not need all the earnings of the business for current personal needs, the excess could be left in the corporation, thereby deferring tax otherwise applying to a dividend. That excess may be invested by the corporation (though some professions are limited in this respect), with the earnings and originally invested principal paid out as dividends when desired in future.
As you may expect, the actual tax operation of a corporation is more complex than this high-level outline. Our Tax & Estate InfoPage titled Illustrated corporate-personal tax integration explains these concepts step by step, and our Tax & Estate InfoCard titled Personal and corporate tax integration – 2015 summarizes the current effective rates by province and income type.
Qualifying professionals and shareholders
To one degree or another, incorporation is available to the traditional professions: accountants, doctors, dentists, engineers and lawyers. As well, those who provide services subject to provincial licencing are often able to incorporate, for example in health care support and a variety of financial services. Normally this is achieved through a combination of a provincial regulation and a bylaw passed by the particular profession’s governing body.
Beyond the professional personally, other individuals may also be allowed as shareholders, though without voting control. At the least, that usually means a spouse and children, but it may extend to parents, siblings, other blood relatives and possibly beyond. Those other shareholders will be able to receive dividends and may be entitled to some amount of the proceeds of the future sale of the practice.
