Paying Yourself as an Ontario Sole Proprietor: How It Works and What It Means for Your Taxes

When you run your own business as a sole proprietor, one of the first practical questions is deceptively simple: how do I pay myself? The answer surprises many people who are used to employment — there is no salary, no T4, and no payroll to run. Instead, every dollar of net profit the business earns is automatically your personal income. Understanding this mechanic is essential to managing your tax obligations and keeping your cash flow predictable.

No Salary Exists in a Sole Proprietorship

Unlike a corporation — which is a separate legal entity that can pay its owner a salary or dividends — a sole proprietorship is legally inseparable from you, the owner. The business does not pay you; it is you. Any money you transfer from a business bank account to a personal account is called an owner's draw, but it carries no special tax significance. You are simply moving money from one of your pockets to another.

What matters for tax purposes is not how much you drew — it is how much the business earned after deducting allowable expenses. That net profit is your business income and it flows directly onto your T1 personal tax return for the year.

How Net Business Income Is Taxed

Your net business income is added to all your other income sources (employment income from a second job, investment income, etc.) and taxed at progressive federal and Ontario marginal rates. The more you earn in total, the higher the marginal rate that applies to each additional dollar.

There is no separate "business tax" for sole proprietors. You file one T1 General personal return that captures everything, and the business income is detailed on Schedule T2125 "Statement of Business or Professional Activities."

The Timing Difference: You Pay Tax on Profit, Not on Draws

This is a critical point. Suppose you earned $90,000 in revenue, had $30,000 in expenses, and drew $40,000 into your personal account. You will be taxed on $60,000 of net business income — not on the $40,000 you drew and not on the $90,000 in revenue.

If the business retained $20,000 in a business account at year-end, that money was still earned and is still taxable income in that year. The retained cash does not defer tax the way retaining earnings inside a corporation can.

Cash-Flow Planning: Setting Aside Tax

Because no employer withholds income tax for you, managing cash flow is your responsibility. A common practice is to set aside a percentage of every payment you receive — often 25–35%, but the right amount depends on your income level, province, and deductions — into a separate account designated for taxes.

The CRA will also expect quarterly tax instalments if your balance owing exceeds a threshold in the current and prior year (see our instalments article in this series). Failing to pay instalments when required leads to interest charges.

CPP Contributions: You Pay Both Sides

Employees and employers each pay a portion of Canada Pension Plan (CPP) contributions. As a sole proprietor, you are both — so you pay the full self-employed CPP contribution rate on your net business earnings, up to the annual maximum pensionable earnings (as of writing — confirm the current rate and ceiling with the CRA). The amount is calculated on Schedule 8 of your T1.

There is a partial offset: the employee half of your CPP contribution is deductible from income, and the employer half generates a tax credit. An accountant will handle this on your return.

Owner's Draws and Business Bookkeeping

Even though draws have no direct tax consequence, tracking them in your bookkeeping matters for several reasons:

• It keeps your personal and business finances clearly separated (important if the CRA audits the business)
• It helps you calculate ending equity in the business for your own records
• Lenders and potential business buyers may want to see clean books

Use accounting software to record every draw as an equity withdrawal rather than an expense. Owner's draws are not deductible as a business expense — you cannot pay yourself a "salary" and deduct it the way a corporation deducts employee salaries.

When Does the Corporation Option Become Attractive?

Incorporation creates a separate taxable entity. A corporation's first tranche of active business income is taxed at the small business deduction rate — significantly lower than personal rates — and that difference can be retained inside the corporation to grow or be reinvested. The tax advantage grows as your business income increases.

However, incorporating adds complexity and cost: annual corporate tax returns, potential payroll, legal fees. The break-even point varies. We have a separate article in this series on when incorporation makes tax sense.
