Rank #11 at $100k net profit · $32,208 total · QPP
Quebec taxes sole-proprietor net business income through federal + Quebec brackets, plus Quebec Pension Plan (QPP) at self-employed (employee + employer) rates. Rankings use a single-filer vignette with $0 expenses and no other income. Total burden = income tax (after Schedule 8 CPP/QPP deductions and credits) + self-employed CPP/QPP. Voluntary EI is off by default. Quebec uses QPP (combined employee rate 6.3% on pensionable earnings) instead of CPP; self-employed pay both halves. Quarterly instalment estimate follows the engine: income tax ÷ 4 when modeled net tax exceeds the CRA threshold ($3,000; $1,800 in Quebec).

Quebec taxes sole-proprietor net business income through federal + Quebec brackets, plus Quebec Pension Plan (QPP) at self-employed (employee + employer) rates. Rankings use a single-filer vignette with $0 expenses and no other income. Total burden = income tax (after Schedule 8 CPP/QPP deductions and credits) + self-employed CPP/QPP. Voluntary EI is off by default. Quebec uses QPP (combined employee rate 6.3% on pensionable earnings) instead of CPP; self-employed pay both halves. Quarterly instalment estimate follows the engine: income tax ÷ 4 when modeled net tax exceeds the CRA threshold ($3,000; $1,800 in Quebec).
At $100,000 net profit on this 2026 model, total income tax + QPP is about $32,208 (rank #11 of 13). That splits into roughly $22,417 income tax and $9,791 QPP.
Quebec replaces CPP with QPP. Higher pension premiums raise the cash bill and change Schedule 8 deductible amounts, so federal tax dollars can differ from an otherwise identical CPP province even though federal rates are unchanged.
Quebec is about $6,204 higher than Nunavut (lowest) and about $1,175 lower than Nova Scotia (highest) at $100k net profit.
A planning quarterly instalment figure at $100k is about $5,604 when CRA instalment rules apply (threshold $1,800).

Progressive federal brackets after the Schedule 8 CPP/QPP deduction and credits. At $100,000 net profit on this model, combined income tax in Quebec is about $22,417. About $12,485 of the $100k income-tax total is provincial/territorial (including Ontario Health Premium where modeled).
Quebec ordinary income tax on taxable income (plus Ontario Health Premium where modeled). Federal bracket rates are the same nationwide; this layer is the main reason rankings differ outside Quebec.
Self-employed QPP = employee + employer portions on pensionable business income. CRA 2026 base CPP: YMPE $74,600, employee/employer rate 5.95% each, max self-employed base contribution $8,460.90. CPP2/QPP2 applies above YMPE up to YAMPE ($85,000). At $100k here, QPP totals about $9,791.
These CRA deadlines apply nationwide (Quebec uses a lower instalment threshold). Confirm in My Account.
Any tax balance for the prior year is due April 30 even if you qualify for the later self-employed filing date.
CRA generally allows June 15 filing if you or your spouse/common-law partner carried on a business. Payment is still due April 30.
When CRA instalment rules apply (net tax over $3,000, or $1,800 in Quebec, for the current year and a prior year), quarterly due dates are March 15, June 15, September 15, and December 15.
Track taxable supplies against the $30,000 small-supplier threshold (four consecutive calendar quarters). Registration is separate from income-tax instalments.
Allowable expenses reduce net business income before tax and CPP/QPP — use the calculator with real expenses. CRA Form T2125 is the usual statement for business or professional activities.
Unlike T4 employment, you fund the employer half yourself. At $100k in Quebec, that layer is about $9,791.
Taxable supplies over $30,000 generally require GST/HST registration under CRA small-supplier rules (some sectors must register even as small suppliers).
Balance owing is due April 30 even if the return is due June 15. CRA instalment due dates are March 15, June 15, September 15, and December 15 when prior-year net tax crossed $1,800.
Self-employed people pay both the employee and employer portions of CPP (or QPP in Quebec) on the personal return.
CRA’s later filing date for many self-employed returns does not change the April 30 due date for any balance owing.
Federal bracket rates are the same nationwide. Provincial tax (and QPP vs CPP) create the gap — e.g. Alberta ~$28,105 vs Ontario ~$28,338 at $100k on this model.
GST/HST is a separate sales-tax account. This ranking excludes GST/HST; register when taxable supplies exceed $30,000 under CRA small-supplier rules.
