Sole Proprietorship vs Corporation

One of the first structural decisions for an Alberta business is whether to operate personally as a sole proprietor or create a corporation. Neither structure is automatically best. The right choice depends on the business, its risk, profits, ownership plans and the owner’s circumstances.

What is a sole proprietorship?

A sole proprietorship is an unincorporated business owned by one individual. Legally, the owner and the business are not separate persons. Business income and expenses are generally reported through the owner’s personal income-tax return.

This structure is relatively straightforward, which is one reason many people use it when starting small.

What changes when you incorporate?

A corporation is a separate legal entity. It can own property, enter contracts, earn income and owe debts. The corporation files its own income-tax return and has ongoing corporate record and filing obligations.

The shareholder owns shares in the corporation rather than directly treating every corporate dollar as personal money.

Limited liability has limits

Limited liability is one reason people consider incorporation, but the phrase can be oversimplified. Incorporation does not make an owner immune from every business risk.

Directors can have personal obligations in certain circumstances. Owners may personally guarantee loans or leases. A person can remain responsible for their own negligent conduct. Insurance and good operating practices remain important even when a business is incorporated.

Taxes are more complicated than comparing tax rates

It is tempting to compare the corporate tax rate with a personal tax rate and conclude that incorporation automatically saves tax. That ignores what happens when corporate money is eventually paid to the owner.

Salary, dividends, retained earnings, deductions and the owner’s other income can all affect the result. Incorporation can create useful planning opportunities, particularly when profits can remain in the company, but the actual benefit is individual.

Administration costs more

A corporation generally means more bookkeeping, a separate corporate tax return, corporate records and annual filings. Professional accounting and legal costs can therefore be higher.

Those costs should be compared with the real benefits the corporation provides, not treated as an unavoidable sign that the business has become successful.

Think about ownership and succession

A corporation can make it easier to define ownership through shares and can be useful when adding shareholders or planning a future transfer. But shareholder relationships create their own legal and financial issues.

If more than one person will own the company, professional advice about a shareholder agreement can be valuable before a disagreement occurs.

When a sole proprietorship can make sense

A sole proprietorship may suit a relatively simple owner-operated business with modest risk and straightforward finances. It can allow someone to test a business idea without immediately creating a more complex corporate structure.

The business can potentially incorporate later if circumstances change.

When incorporation deserves closer consideration

Incorporation may deserve more attention when the business is generating profits beyond what the owner needs personally, has meaningful contractual or operational risks, will have multiple owners, is building assets or intellectual property, or is being developed for future succession or sale.

These are reasons to investigate incorporation, not universal rules.

Ask the question in dollars and obligations

Before incorporating solely because someone said it saves tax, ask an accountant to compare the likely outcomes using the business’s actual numbers. Before incorporating solely for liability protection, ask a lawyer and insurance professional what risks would actually remain.

Structure should solve a real problem.
