Quick answer
On $100,000 of profit in 2026, a Nova Scotia sole proprietor pays $24,090 in income tax and $9,293 in CPP, while a corporation paying the same profit out as dividends pays $27,833 in income tax between the company and its owner, and no CPP. In Newfoundland and Labrador it is $22,406 and $9,293 against $24,636. For the year, the gap widens when profit stays in the company: it is taxed at the small business rate, and the owner’s personal tax on it is deferred until it is paid out, not removed. A corporation also adds a tax return, paperwork and a separate legal entity whose protection has limits.
Why start from profit, not revenue?
Income tax is charged on profit, what is left after the business’s expenses. A sole proprietor pays personal income tax on the business’s net income.1 A corporation pays tax on its own taxable income,2 and the owner pays personal tax on what it pays them. Sales say little about either, so the example starts from the same $100,000 of profit in both structures.
What does the example assume?
- The 2026 tax year, for an owner living in Nova Scotia or in Newfoundland and Labrador.3,4,5
- No other income, and no credits beyond the basic personal amount and CPP.
- A Canadian-controlled private corporation with a calendar year, all of its profit taxed at the small business rate.2
- The owner is paid in dividends, not salary: “other than eligible” dividends, the kind paid from income taxed at the small business rate.6,7
- The corporation’s running costs, including its tax return, are left out here and covered below.
- Amounts are rounded to the nearest dollar.
What if the owner takes all of the profit out?
The sole proprietor reports all $100,000 on their own return1 and pays both the employee’s and the employer’s share of CPP on it.8 The corporation pays the small business rate, federal and provincial together: 10.5% in Nova Scotia (9% federal, 1.5% provincial)2 and 11% in Newfoundland and Labrador (9% and 2%, after the province cut its rate from January 1, 2026).9,10 The rest is paid to the owner as a dividend.

|---|---|---|
| Corporate income tax | None | $10,500 |
| Paid to the owner | $100,000 of business income | $89,500 in dividends |
| Owner’s income tax | $24,090 | $17,333 |
| CPP contributions | $9,293 | None |
| Total income tax and CPP | $33,383 | $27,833 |
| Left for the owner | $66,617 | $72,167 |
| For 2026 | Sole proprietor | Corporation |

| Owner’s income tax | $22,406 | $13,636 |

Counting income tax alone, the corporation route pays $3,743 more in Nova Scotia and $2,230 more in Newfoundland and Labrador. Part of the reason is the sole proprietor’s CPP: some of it is deducted from their income and the rest claimed as a credit.11,12 The dividend tax credit exists to make up for the company’s tax on the same profit,6 and how closely it does depends on the province.
Counting CPP, the sole proprietor pays $5,550 more in Nova Scotia and $7,063 more in Newfoundland and Labrador. But that CPP builds a pension, and the dividends do not. Both comparisons also leave out the corporation’s own running costs, covered below.
What if the owner takes out $60,000 and leaves the rest in?
A sole proprietor cannot leave profit in the business to be taxed later: all $100,000 is on their return for 2026, spent or not,1 so their figures do not change. A corporation can. The $40,000 left in is taxed only at the small business rate, and the $60,000 taken out is paid as a dividend after the same tax.
| For 2026 | Sole proprietor | Corporation |
|---|---|---|
| Corporate income tax | None | $10,500 |
| Paid to the owner | $100,000 of business income | $53,700 in dividends |
| Owner’s income tax | $24,090 | $6,324 |
| CPP contributions | $9,293 | None |
| Total income tax and CPP | $33,383 | $16,824 |
| The owner has, after tax | $66,617 | $47,376 |
| Left in the company | No company to leave it in | $35,800 |
| For 2026 | Sole proprietor | Corporation |
|---|---|---|
| Corporate income tax | None | $11,000 |
| Paid to the owner | $100,000 of business income | $53,400 in dividends |
| Owner’s income tax | $22,406 | $4,145 |
| CPP contributions | $9,293 | None |
| Total income tax and CPP | $31,699 | $15,145 |
| The owner has, after tax | $68,301 | $49,255 |
| Left in the company | No company to leave it in | $35,600 |
Part of the difference for the year is CPP the dividend route does not pay. The rest is timing: the personal tax on the money left in the company is deferred, not removed. It is paid in the year the company pays that money out, at that year’s rates and on the owner’s income then.
What does the difference in CPP mean?
A sole proprietor pays both shares of CPP on their profit, up to the year’s maximums: $9,293 on $100,000 in 2026.8,13 It counts toward a CPP retirement pension, which depends on how much and for how long a person contributed.14
Dividends carry no CPP and earn no CPP pension: more in hand now, less pension later. A salary from the corporation brings CPP back, with the company and the owner each paying a share.8 It also builds RRSP room, which comes from the previous year’s earned income.15 Employment and business income are on CRA’s list of earned income, and dividends are not.16 Which mix suits an owner depends on facts this example does not have, so it does not compare them.
What does each structure offer?
As a sole proprietor:
- Simple and cheaper to run. It is the simplest structure: the business’s income or loss goes on your own return, and there is no corporate return.1
- Early losses reach your other income. A business loss can generally be set against your other income for the year, such as wages from a job.17 A corporation’s losses stay in the corporation.18
As a corporation:
- Deferral. Profit left in the company is taxed at the small business rate until it is paid out.
- A separate legal entity. The company owns property and signs contracts in its own name.18,19
- The lifetime capital gains exemption. A gain on selling qualified small business corporation shares can qualify for the capital gains deduction.20 A sole proprietorship has no shares to sell, though qualified farm or fishing property can qualify under either structure.20
- Flexibility in pay. Salary, dividends or a mix, year by year, with the CPP and RRSP consequences above.
- Family members. Dividends paid to family members can fall under the tax on split income, a special tax on certain income from a related business, unless an exclusion applies.21
- More cost and paperwork. A T2 return every year, even with no tax owing,18 its own books, and the company’s annual renewal or annual return with the provincial registry.22,23 A sole proprietor trading under their own name needs no registration in Nova Scotia at all.19
- Moving in later is a transaction of its own. An existing business’s property is transferred to the company, and CRA has a joint election for that transfer, Form T2057.24
Either way, the same small supplier test decides whether the business registers for GST/HST.25
Does a corporation protect my personal assets?
Partly. A sole proprietor carries all of the business’s risks, and CRA notes that they extend to personal property and assets.1 A shareholder has limited liability: the corporation’s debts are not theirs.18 That protection has limits, including these:
- Personal guarantees. A lender or landlord may ask the owner of a small company to guarantee a debt, and an owner who agrees is liable for it if the company does not pay.18
- Money held in trust. Directors can be personally liable for payroll source deductions and GST/HST the company did not remit.18,26
- Your own work. Limited liability is about the company’s debts. Business insurance still matters for the work you do yourself.
What does it cost to run the corporation?
Every corporation files a T2 return each year, even when it owes no tax.18 Ours is from $799 for a company whose books we keep and from $999 otherwise, plus HST.

Frequently asked questions
Is a corporation always cheaper on tax?
No. Here, taking all of the profit out costs more income tax through a corporation, in both provinces. The corporation pays less in total once CPP is counted, though that CPP builds a pension, and less again for the year when profit stays in the company, where the personal tax on it is deferred, not removed.
Do I pay CPP if I incorporate?
Not on dividends. On a salary from your corporation, yes: the company and you each pay a share.8
Does incorporating protect my house?
It keeps the company’s own debts off you as a shareholder,18 but not a debt you guaranteed, or source deductions and GST/HST the company failed to remit while you were a director.26 Business insurance still matters for the work you do yourself.
Does the GST/HST small supplier threshold change if I incorporate?
No. The same small supplier test applies to both structures.25
