Realtor HST/GST Canada 2025 — Registration, Collection & Remittance Guide

Updated March 2026 · Realtor HST GST Canada · 8-minute read

HST/GST is one of the most misunderstood tax obligations for new Canadian real estate agents. Unlike income tax — which you pay on net profit — HST is collected from your clients and held in trust for the CRA. It is never your money. Understanding registration requirements, collection rules, input tax credits, and remittance deadlines is essential for every Canadian realtor.

Critical Rule: Register Before You Hit $30,000

Once your gross annual commissions exceed $30,000 in any single calendar quarter or in four consecutive calendar quarters, you are legally required to register for HST/GST. Most full-time agents cross this threshold very quickly — often after their first or second transaction. You must register within 29 days of exceeding the threshold. Failing to register and collect HST can result in you owing the HST you should have collected, out of your own pocket, plus penalties and interest.

How HST Works on Real Estate Commissions

As a registered HST/GST agent, you must add HST to your commission invoices. When a seller pays a 5% total commission on a $900,000 home sale in Ontario, the buyer's agent and listing agent each invoice their brokerage (or client) for their portion plus HST:

Agent commission (2.5% = $22,500)
HST on commission (13% = $2,925)
Total invoiced: $25,425
You collect $25,425 but remit $2,925 to the CRA
Your income is $22,500 (before brokerage split and other deductions)

The HST collected is held in trust. Never spend it. Keep it in a separate account until your remittance is due. For a zero-fee way to do this, KOHO's savings goals feature lets you earmark funds without paying monthly banking fees.

Input Tax Credits (ITCs)

The major benefit of HST registration is the ability to claim Input Tax Credits (ITCs) — a refund of the HST you paid on business expenses. This offsets some of the HST you must remit.

ITCs you can claim as a realtor:

HST paid on your vehicle (business-use portion)
HST paid on office rent or coworking space
HST paid on advertising and marketing
HST paid on professional fees (accountant, lawyer)
HST paid on software, technology, and equipment
HST paid on MLS fees and board dues
HST paid on continuing education

Quick Method: Simpler HST for Small Businesses

If your annual revenues are under $400,000, you may be eligible for the Quick Method of HST accounting. Instead of tracking every ITC, you remit a flat percentage of your total sales including HST. For service businesses in most provinces, the Quick Method rate is significantly lower than the actual HST rate — often resulting in keeping a small "profit" on the HST collected. For Ontario realtors earning under $400K, the Quick Method rate is approximately 8.8% of gross revenue including HST (vs. 13% collected). This can mean keeping $1,000–$3,000+ per year extra.

HST Remittance Deadlines

Your HST filing and remittance frequency depends on your annual taxable revenues:

Annual filer: Under $1.5M revenues — one HST return per year, due 3 months after fiscal year-end (June 15 for calendar-year filers)
Quarterly filer: $1.5M–$6M revenues — four returns per year
Monthly filer: Over $6M revenues — monthly returns

Most realtors qualify as annual filers. However, you must still set aside HST throughout the year — the annual due date does not mean you can wait to collect it.

Common HST Mistakes Realtors Make

Not registering on time: The CRA can assess HST you should have collected even if you didn't — meaning you owe it out of pocket.
Spending the HST: HST collected is a liability, not income. Realtors who spend it face sudden large tax debts.
Forgetting ITCs: Every business purchase you made with HST has a recoverable ITC. Failing to claim them means paying more than you owe.
Wrong rate: Applying 5% when your province has 13% HST — or vice versa — creates mismatches the CRA will catch.
Not filing a nil return: If you had no revenue in a period, you still need to file a nil return if registered.

FAQs

Do I charge HST on the full sale price of a home?

No — real estate agents charge HST on their commission (their service fee), not on the home sale price itself. New construction homes may have their own HST implications, but that is the developer's/builder's obligation, not the agent's.

Can I voluntarily register for HST before hitting $30,000?

Yes. Voluntary registration lets you claim ITCs on all business purchases from day one, which can be advantageous if you have significant startup expenses. The downside is the administrative burden of filing and remitting.

What happens if I go over $30,000 mid-year and didn't register?

Register immediately — you have 29 days. The CRA can assess HST on transactions that occurred after you crossed the threshold, even if you didn't collect it. You'd owe the HST from your own pocket.
