How Much Is a Broker's Commission on a Plex in Quebec?
In Quebec, a real estate broker's commission on a plex is negotiable, with no imposed rate. We break down the impact at 4%, 5% and 6%, including taxes (GST/QST), across the most common price ranges.
Quick answer
In Quebec, a real estate broker's commission on a plex is negotiable, generally 4 to 6% of the sale price, plus GST/QST taxes (14.975%). On a $1,000,000 property at 5%, that amounts to $50,000 + taxes ≈ $57,500. No rate is set by law or by the OACIQ. Selling to a direct buyer eliminates this commission entirely.

The question comes up often: how much does a broker's commission really cost on an income property? The answer depends on the negotiated rate, but mainly on the sale price — and on a multiplex, those percentages quickly add up to tens of thousands of dollars. This guide breaks them down concretely, bracket by bracket.
How commission works in Quebec
In Quebec, the brokerage commission is entirely negotiable. No law and no OACIQ (Organisme d'autoréglementation du courtage immobilier du Québec) regulation sets the rate: it is recorded in the brokerage contract signed between the seller and the broker. The rate, structure (flat rate or tiered by achieved price), and contract duration are freely negotiated.
On income properties, the typical rate is often between 4% and 6% of the sale price — sometimes more on small properties, sometimes less on large transactions. To that are added GST (5%) and QST (9.975%), totalling 14.975% calculated on the commission, not on the property price.
In standard Quebec practice, the total commission in the seller's contract covers both the seller's broker and the buyer's broker. The seller therefore bears the full cost, even when two brokers are involved.

Illustrative figures as of June 22, 2026. GST (5%) + QST (9.975%) = 14.975% apply on the commission. Actual rates are negotiable and vary by contract. Source: OACIQ (no imposed rate), Revenu Québec (tax rates). This does not constitute financial advice.
On a $1,000,000 property at 5%, the commission amounts to $57,488 including taxes. At $2,000,000, even at 4%, nearly $92,000 comes out of your sale price. This amount covers both the seller's broker and the buyer's broker — the seller pays it all. The only way to bring this cost to zero: sell directly to a professional buyer without a broker.
What you get with a broker — and what you avoid without one
What commission covers
A real estate broker specializing in income properties brings real value: MLS listing, professional photos, targeted marketing, showing and negotiation management, and access to a qualified buyer network. In a competitive market where the property shows well, this exposure can generate multiple offers and push the price above the commission cost. In that scenario, a good broker clearly earns their fee.
Commission also generally covers the buyer's broker (buyer's agent) — this split is recorded in the seller's brokerage contract. The seller does not receive two separate invoices but bears the full total commission.
The 0% alternative: the direct buyer
Selling directly to a professional buyer like ImmoMulti generates $0 in commission. On a $1,000,000 property, that is approximately $57,500 (at 5% including taxes) that stays in your pocket. The direct buyer evaluates the property based on actual income, makes a firm offer within 48 h, and closes in 30 to 45 days — no showings, no public listing, no post-inspection renegotiation.
This option is advantageous when you want to sell quickly, discreetly, or as-is (without prior renovations), or simply avoid the delays and costs of a public market listing. For a detailed comparison of methods, see our guide broker vs direct buyer.
Maximum market exposure
MLS listing, professional photos, managed showings, negotiation, access to a buyer network. Commission: ~4 to 6% + taxes. Typical timeline: 2 to 6 months. Relevant if you believe public competition will exceed the commission cost.

The commission rate is negotiable and no rate is imposed in Quebec (neither by law nor by the OACIQ). On an income property, it generally ranges from 4% to 6% of the sale price, with a common rate of around 5%. GST (5%) and QST (9.975%) — totalling 14.975% — are added on the commission. Example: $1,000,000 × 5% = $50,000 + taxes ≈ $57,500.
Yes. Brokerage commission is subject to GST (5%) and QST (9.975%), totalling 14.975% applied on the commission amount — not on the property sale price. Example: $50,000 commission × 14.975% = $7,488 in taxes = total of $57,488.
Yes. No law or OACIQ regulation sets the commission rate: it is fully negotiable between the seller and the broker and recorded in the brokerage contract. The rate, structure, and contract duration are discussed freely. On high-value income properties, many owners negotiate a lower rate than on a single-family home. Always compare what each option leaves you net.
The most direct way is to sell without a broker to a specialized direct buyer like ImmoMulti: $0 commission. On a $1,000,000 property at 5% + taxes, that is approximately $57,500 that stays in your pocket. See our comparison broker vs direct buyer and our guide on the full cost of selling an income property.
Yes, in general. In standard Quebec practice, the total commission agreed in the seller's brokerage contract covers both the seller's broker and the buyer's broker — the seller's broker shares their commission with the buyer's broker. The seller does not receive two separate invoices but bears the full cost of the total commission.
