Does HST Apply to Real Estate Commission in Ontario?

Yes. When an Ontario brokerage is registered for GST/HST, it charges 13% HST on its commission. The tax is on top of the commission unless the agreement clearly says the figure already includes tax. On a $800,000 sale with a 5% commission, the commission is $40,000 and the HST is $5,200, for $45,200 leaving the seller's proceeds. There is no statute that sets the commission rate itself. The rate is whatever the seller and the brokerage agree, and TRESA requires that agreement to state an amount, a percentage, or both.

Two HST questions get mashed together in kitchen-table math. HST on commission is almost always a seller-side cost. HST on the purchase price of a resale home is usually not charged at all. This article separates them. It is not tax advice for a specific brokerage or a specific property.

Where does the 13% sit on a net sheet?

Build the seller's net sheet in this order, and label each line.

Change the percentage and the HST changes with it. A 4% commission on the same sale is $32,000 plus $4,160 HST. Quoting "about 5% all in" hides a four-figure tax line. Sellers compare agents on the all-in number, then feel misled when the trade record shows tax on top. Show both lines every time.

The listing agreement's commission clause is the source. Standard Ontario wording says the amounts set out as commission are plus applicable taxes. If you are offering a fee that includes HST, the agreement has to say so in words a stranger can read. Verbal "I'll look after the tax" is how net sheets and trade records diverge.

What does TRESA actually fix?

The Trust in Real Estate Services Act, 2002 does not pick a rate. It does require that remuneration agreed with a client be a fixed amount, a percentage of the sale price, or a combination of the two. A stepped percentage, lower on the portion of the price above a threshold, can fit that. A deal that pays the brokerage "whatever you can get over the list price" does not. That structure is prohibited because it pays the brokerage the difference between the list price and the sale price.

There is a second money rule agents should be able to say cleanly. If the remuneration terms could affect whether an offer is accepted, the brokerage has to disclose those terms to anyone who makes a written offer, as soon as possible after the offer and before any offer is accepted. A reduced commission that only applies if the buyer is a client of the listing brokerage is the classic case. Hide it and you have a disclosure problem, not a clever pricing tactic.

None of that sets HST. Registration with CRA sets HST.

When is HST not charged?

CRA's small-supplier rule is the exception. A person whose taxable revenues are at or under the $30,000 threshold, and who is not registered, does not charge GST/HST. The moment they are registered, they charge it, including on commission. Brokerages that do any volume are registrants. An individual agent who is paid as an independent contractor still usually has HST in the picture because of how the brokerage invoices the seller.

Do not build a listing presentation around "no HST" unless the broker of record has told you, in this year, that this invoice will not carry it. If you are a registrant, you charge 13% on the commission, you remit it, and you claim input tax credits on your own taxable expenses the way your accountant sets up. The HST the seller pays is not your income. Treating it as income is how people overstate what they "made" on a deal. The income article is a different topic: how much Ontario agents make.

How is this different from HST on the house?

Most used residential property is exempt from HST. The buyer of a resale house or condo does not add 13% to the price. The seller of that resale does not remit HST on the price. New construction, and some substantial renovations, are taxable. So are some properties that were used as short-term rentals in a way that changes the exempt status. The standard resale agreement has a clause that says whether HST is included in the price or in addition to it, and a seller warranty when HST does not apply.

If a seller checks "included" and HST turns out to apply, the tax comes out of their proceeds. If the clause says "in addition," the buyer pays it on top. Flag the clause before the offer is firm whenever the property is new, was just heavily renovated, or was rented nightly. Then stop. The lawyer determines whether this property is taxable.

Land transfer tax is a third number. It is not HST. The Ministry of Finance is explicit that when HST is payable on a purchase, that HST is not included in the value of the consideration for land transfer tax. Three taxes, three lines. They are laid out for buyers in closing costs when buying a home in Ontario.

What should the listing presentation show?

One sample net sheet at the price you are recommending, with commission and HST as separate lines, plus a blank for the mortgage payout and a blank for legal fees. Circle the HST line. Say "this is 13% of the commission, not 13% of your sale price." That single sentence prevents the most common panic.

Then write the agreed rate into the agreement exactly, plus tax, and keep a copy of the net sheet in the file. When an offer arrives, update the same sheet. Do not switch to a back-of-envelope number that drops the tax because the offer is exciting.

Who remits the tax, and what does the agent actually keep?

The seller pays the commission and the HST on that commission to the brokerage. The registered brokerage is the one that charges the tax and remits it. The HST line is not a tip, and it is not part of the agent's split. On the $800,000 example, the $5,200 does not become income because it passed through the deal. Adding it to "what I made" overstates the cheque and understates the tax the brokerage has to send on.

Run a second price so the seller can see the tax move with the fee. These percentages are illustrations, not a going rate:

The total remuneration in the listing agreement is the number HST applies to. An amount the listing brokerage offers a cooperating brokerage sits inside that agreement. It is not a second, tax-free fee stacked on top, and it is not a reason to hide HST from the seller's net sheet. How the two brokerages invoice each other is their own tax filing. The seller still sees one commission line and one HST line.

The small-supplier exception is narrower than agents remember. CRA's threshold is $30,000 of taxable supplies. It is measured over the last four consecutive calendar quarters, and a single calendar quarter can end small-supplier status as well. Read the current page before anyone relies on it. Brokerages with any real volume are past it and are registered. The moment a person is registered, they charge GST/HST, including on commission. "We don't charge HST" is a sentence only the broker of record should authorize, for this invoice, this year.

New construction is the other mash-up. HST on a new home, and any new-housing rebate assigned to a builder, is tax on the property. It is not HST on commission. Rebate amounts and price thresholds change, and the builder's schedule is the document that shows whether the sticker price already assumes a rebate. Do not quote a rebate dollar figure from a course you took. Flag the clause and send it to the lawyer.

Resale residential property is usually exempt, which is why a normal house does not grow by 13% on the statement of adjustments. Substantial renovation and some short-term rental histories can change that. The agreement's HST clause, included versus in addition, decides whose proceeds absorb the surprise if the exemption does not hold. Circle that clause when the property is new, freshly and heavily renovated, or was rented nightly. Then stop talking.

If you are registered in your own right because of how you invoice the brokerage, your accountant sets up that return. It does not change the sentence you owe the seller: 13% on the commission, on top, unless the agreement says the figure already includes tax.

Commission is the fee in the agreement. HST is 13% on that fee when the brokerage is registered. The house price is not the thing being taxed in that line.

Sellers can compare agents on service and on price. They cannot compare them if one quote includes tax and the other does not. Put the tax on the page.
