Should I incorporate? Self-employed vs corporation in Quebec
There is no universal dollar rule for deciding whether to incorporate. The choice depends on business profit, what the owner needs to live on, whether money can stay in the company, and the extra yearly cost and paperwork. A corporation is a separate legal entity, but limited liability and reduced tax rates have limits.
Self-employed: which returns and deadlines?
A self-employed individual reports business income on T1 and TP-1 returns. File by June 15 and pay by April 30.
When instalments are required, the deadlines are March 15, June 15, September 15 and December 15.
Corporation: a separate entity and separate returns
A corporation is a separate legal entity and files a federal T2 return and a Quebec CO-17 return. The T2 is due within six months of the year-end.
Tax is generally payable two months after the year-end, or three months for some Canadian-controlled private corporations claiming the small business deduction. The T2 filing deadline is therefore not necessarily the payment deadline.
Which rates should I compare, and what did Quebec announce?
The federal small business rate is 9% on the first $500,000 of active business income; the general federal rate is 15%. Quebec’s general rate is 11.5%.
Quebec announced in bulletin 2026-3, dated April 29, 2026, that its small business rate would drop from 3.2% to 2.2% for tax years starting after April 29, 2026. This is an announced measure: check its application to your tax year and your eligibility before using that rate.
Quebec’s small business deduction generally involves a paid employee-hours condition — a threshold of 5,500 hours reduced to 5,000 hours — or at least 50% primary or manufacturing activities. Confirm the applicable hours requirement. Many one-person corporations do not qualify and pay Quebec’s general rate; incorporation alone does not provide the reduced rate.
What additional administration is involved?
A corporation registers with the Registraire des entreprises and files an annual updating declaration. Consult the registry’s official fee page for applicable charges.
Corporate returns, annual updating and other formalities add administrative work and a yearly cost. Include these in the comparison with self-employment.
Does limited liability protect against everything?
No. Directors can be liable for unremitted source deductions and GST/QST. Limited liability does not remove those obligations.
Personal guarantees may also be required for a loan or lease. A separate corporate entity does not eliminate every personal commitment made by its owner.
How do I decide without an automatic dollar rule?
Compare business profit with the money you need to live on. The ability to keep money in the company, extra annual costs and paperwork can change the value of incorporation.
The choice deserves a consultation based on your situation rather than a universal threshold. We can discuss these factors with you before you make a decision.
Check before acting
Confirm the start of your tax year, the application of the announced rate reduction and Quebec small business deduction conditions, including the 5,500-hour criterion and its reduction to 5,000 hours. Do not assume a one-person corporation receives the reduced rate.
Check filing and payment deadlines, required instalments, annual administration, official fees and personal guarantees. This page provides general information, not tax or legal advice tailored to your situation.
Frequently asked questions
Is there a specific income level at which I should incorporate?
No. There is no universal dollar rule. The decision depends on profit, what the owner needs to live on, money that can stay in the company, and extra annual costs and paperwork.
Does a one-person corporation automatically get Quebec’s reduced rate?
No. Many one-person corporations do not meet Quebec small business deduction conditions and pay Quebec’s general rate. Paid employee-hours or primary or manufacturing activity conditions must be checked.
Does incorporation eliminate all personal liability?
No. Directors can be liable for unremitted source deductions and GST/QST, and personal guarantees may be required for loans or leases.
