Two returns. Two tax payments. Two sets of rules, rates, and deadlines. For a salaried employee in Quebec, all of this happens behind the scenes — the employer handles it. For a self-employed person, this reality lands directly on your desk every year. Understanding who does what between the Canada Revenue Agency (CRA) and Revenu Québec is not administrative trivia — it is a basic requirement to avoid missing a deadline, underpaying into your retirement, or missing an instalment payment.
Why Quebec Is Unique in Canada
Quebec is the only Canadian province that collects its own income tax entirely independently, through its own agency: Revenu Québec. In the other nine provinces and the territories, the CRA administers both federal and provincial income tax — taxpayers deal with a single organization.
In Quebec, the two systems coexist in parallel and independently. They share the same gross income base, but then diverge on rates, eligible deductions, available credits, and even some expense definitions.
Who Administers What
| Agency | What It Collects |
|---|---|
| CRA | Federal income tax · Canada Pension Plan (CPP) · Employment Insurance (EI) |
| Revenu Québec | Provincial income tax · QST · Quebec Pension Plan (RRQ) · Quebec Parental Insurance Plan (RQAP) |
As a self-employed person in Quebec, you file two separate returns — the T1 with the CRA and the TP-1 with Revenu Québec — and you make payments separately to each agency. There is no single window.
RRQ vs CPP — Retirement, Quebec Style
Self-employed persons in Quebec do not contribute to the Canada Pension Plan (CPP). Instead, they contribute to the Quebec Pension Plan (RRQ), administered by Revenu Québec.
For 2025, the RRQ contribution rates for a self-employed person are:
| Parameter | 2025 Value |
|---|---|
| Total contribution rate (self-employed) | 10.8% |
| What you pay (equivalent of both employee and employer shares) | 5.4% × 2 = 10.8% |
| Maximum Pensionable Earnings (MPE) | $71,300 |
| Basic exemption | $3,500 |
Unlike an employee who shares the contribution with their employer (5.4% each), a self-employed person covers both shares — 10.8% on net business income, up to the MPE. This is one of the most significant charges to anticipate when calculating your instalment payments.
RRQ contributions are declared on your TP-1 and paid to Revenu Québec — they do not appear on your federal T1 (where CPP contributions would appear, but which do not apply to you).
RQAP — A Strictly Quebec Feature
The Quebec Parental Insurance Plan (RQAP) is another contribution you will not find in any other province. It provides access to maternity, paternity, adoption, and parental benefits — and self-employed Quebecers are required to contribute, unlike federal Employment Insurance, from which they are generally excluded.
For 2025:
| Parameter | 2025 Value |
|---|---|
| Contribution rate (self-employed) | 0.494% |
| Maximum insurable income | $98,000 |
| Maximum annual contribution | ~$484 |
The RQAP contribution is calculated on your net business income, up to the $98,000 ceiling. It is declared on your TP-1 and paid to Revenu Québec.
Instalment Payments — Two Systems, Two Thresholds
Self-employed income is not withheld at source. You are responsible for making instalment payments throughout the year to avoid an unexpected bill (and interest charges) when you file your return.
The two governments have different triggering thresholds:
| Government | Triggering Threshold | Agency |
|---|---|---|
| Federal (CRA) | Net tax owing > $3,000 in the current year AND in one of the two preceding years | CRA |
| Provincial (Revenu Québec) | Net tax owing > $1,800 in the current year AND in one of the two preceding years | Revenu Québec |
The provincial threshold is lower: you may owe instalments to Revenu Québec without owing any to the CRA. Both agencies use the same four annual payment dates:
- March 15
- June 15
- September 15
- December 15
You make two separate transfers on those dates: one to the CRA (if applicable) and one to Revenu Québec (if applicable). Neither agency is automatically notified of the payment made to the other.
Practical tip: If this is your first year as a self-employed person, you will not owe instalments for that year — but as early as the following year, you may be subject to them. Anticipate this obligation now rather than being caught off guard in March.
Meals and Entertainment — A Rule That Differs Between the Two
Business meal expenses are a good illustration of how the rules can diverge between the two governments. On the federal side, the rule is uniform: 50% of eligible expenses. On the provincial side, Revenu Québec applies the same 50% limit, but then caps the deduction based on gross business income:
| Gross Business Income | Provincial Limit |
|---|---|
| $32,500 or less | 2% of gross income |
| Between $32,500 and $52,000 | $650 (fixed amount) |
| $52,000 and over | 1.25% of gross income |
This asymmetry — same expense, two different calculations — is representative of the reconciliation effort you must make for every expense category between your T2125 and your TP-80-V.
