Sole proprietorship vs incorporation in Canada comes down to liability, tax and cost. A sole proprietor does not have separate legal status from the business: business income is reported on the owner’s personal return, generally using Form T2125 (farming and fishing income use different forms), and the business’s risks extend even to the owner’s personal property and assets. A corporation is a separate legal entity that normally files its own T2 corporate income tax return. CRA: sole proprietorship; CRA: corporation.
Sole proprietorship vs incorporation: key differences
| Question | Sole proprietor | Corporation |
|---|---|---|
| Legal identity | The owner and business do not have separate legal status. | The corporation can own property and enter contracts in its own name. |
| Reporting business income | Net income or loss is reported on the owner’s T1, usually using T2125. | Resident corporations generally file a separate T2 each tax year, including inactive corporations, subject to exceptions. |
| Personal exposure | Business risks can extend to the owner’s personal assets. | Shareholder limited liability has exceptions: a personal guarantee or certain director liabilities can create personal exposure. |
| Access to profits | Business profit is the proprietor’s income whether or not cash is withdrawn. | Corporate income and amounts paid to an owner are distinct; salary, dividends and other transactions have different rules. |
| Income tax | The owner pays personal income tax on the net income generated by the business. | For a CCPC claiming the small business deduction, the federal net tax rate is 9% (4.5% for manufacturers of qualifying zero-emission technology). |
| CPP contributions | May have to make CPP or Quebec Pension Plan payments on self-employed earnings, depending on age, earnings and other conditions; for CPP, a self-employed person pays both the employer and employee contribution, up to the self-employed maximum, as part of their personal income tax return. | Generally, CPP contributions are deducted from salary paid to an employee who meets CRA’s conditions; QPP contributions are deducted instead if the province of employment is Quebec. |
| Setting up | An unincorporated business owned by one individual. | Set up by completing articles of incorporation and sending them to the appropriate provincial, territorial or federal government. |
| Ongoing administration | Track revenue, expenses and any GST/HST obligations. | Maintain corporate records, separate financial statements and applicable corporate, payroll and sales-tax filings. |

How a sole proprietor reports business income
A sole proprietor reports business or professional income on Form T2125, Statement of Business or Professional Activities, filed with the personal T1 (farming and fishing income use different forms); see CRA’s self-employed guide and our how to complete Form T2125 guide for the expense categories, capital cost allowance and GST/HST input tax credit rules, including CRA’s expenses section.
For example, a consultant with $90,000 of revenue and $25,000 of eligible expenses has $65,000 of net business income before other adjustments; other income, allowable deductions, credits and CPP or QPP can change the final result.
How do corporate tax and owner pay differ?
The corporation reports its income and expenses on its own T2. An owner who takes salary or dividends also has personal reporting consequences; salary may involve payroll withholding and pension contributions, while dividends follow different rules. The total result depends on the applicable corporate and personal tax rules, the amount retained, the way funds are paid out, and the owner’s other income. Compare both the business and personal sides over the same period before deciding. CRA: corporation.
A corporation may be a personal services business if the facts meet CRA’s conditions, with special income-tax rules. Incorporating a working arrangement does not automatically settle whether those rules apply. CRA: personal services business.
Will you pay less tax if you incorporate?
Not automatically. For a Canadian-controlled private corporation (CCPC) claiming the small business deduction, the federal net tax rate is 9% (4.5% for manufacturers of qualifying zero-emission technology); the maximum business limit for a corporation that is not associated with any other corporation is $500,000. After the general tax reduction, the federal net tax rate is 15% (7.5% for manufacturers of qualifying zero-emission technology), but that reduction does not apply to income earned from a personal services business. Generally, provinces and territories have two rates of income tax: a lower rate and a higher rate. CRA: Corporation tax rates.
A corporation generally has to file a T2 return every tax year, even if it does not owe taxes. Compare the combined corporate-plus-personal tax on money actually withdrawn, not the corporate rate alone, before assuming incorporation lowers your tax.
Can a sole proprietorship be converted to a corporation?
Moving from a sole proprietorship to a corporation is a change of legal status:
- Complete articles of incorporation and send them to the appropriate provincial, territorial or federal government.
- Give the corporation its own business number and register any program accounts it needs, such as GST/HST, on the new BN.
- Ask CRA or an advisor whether existing contracts, assets or debts can move to the corporation without an immediate tax cost before assuming that is the case.
- Review which contracts, invoices and accounts should be in the corporation’s name, since a corporation can enter into contracts and own property in its own name.
- If the sole proprietorship has a business number, close it and any CRA program accounts on it; program accounts on the old BN, such as a GST/HST account, are not automatically associated with the corporation’s new BN. CRA: change of legal status.
GST/HST applies to both structures
Sole proprietors and corporations can each have GST/HST registration and filing obligations. The ordinary small-supplier threshold generally considers relevant worldwide taxable supplies of the person and associates; assess the particular entity and its circumstances. A new corporation is a separate entity, so review registration, account details, contracts, invoice identity and any transfer of assets before the switch. Do not simply assume the sole proprietor’s GST/HST account covers the corporation. CRA: when to register.
Quebec has separate QST requirements; Revenu Québec generally administers GST/HST for businesses physically located in Quebec, with an exception for selected listed financial institutions. CRA: GST/HST general information.
Questions to take to an adviser
- How much profit must you withdraw for living costs, and how much might stay in the business?
- What are the setup, bookkeeping, annual return and payroll costs in your province?
- What contracts, assets, loans, licences and insurance need to change, and do any lenders require personal guarantees?
- Could personal services business rules or a transfer of existing assets affect the proposed structure?
- What GST/HST and provincial registrations, invoices and filing periods will each entity need?
There is no universal income level at which incorporation pays for itself. Compare realistic after-tax cash and ongoing costs, and obtain advice on your specific circumstances before transferring a business.
