Mississauga's Commercial Property Tax Rate Is 2.298223% — More Than Double What Homeowners Pay
Mississauga's 2026 commercial property tax rate is 2.298223% — more than double the 1.087901% residential rate. Here's exactly why, and what it means for owners and tenants.
Every Mississauga small business guide on this site so far has covered licensing, zoning, and HST — the compliance side of running a business here. This one covers the cost that's easy to overlook until a lease renewal or a tax bill puts a number on it: property tax is not the same tax for a business as it is for a home, and the gap is large enough to change the math on buying, leasing, or renewing.
What Each Property Class Actually Pays in 2026
The City of Mississauga sets one tax rate per property class each year under its annual tax ratios and rates by-law. For 2026, that's By-law 0061-2026, and its Schedule A breaks every class into three components: the City's own portion, the Region of Peel's portion, and the provincial education portion.
| Property Class | City Rate | Region Rate | Education Rate | Total Rate |
|---|---|---|---|---|
| Residential (RT) | 0.396141% | 0.538760% | 0.153000% | 1.087901% |
| Commercial / Office / Shopping Centre (CT / DT / ST) | 0.600937% | 0.817286% | 0.880000% | 2.298223% |
| Industrial / Large Industrial (IT / LT) | 0.639777% | 0.870108% | 0.880000% | 2.389885% |
| Multi-Residential (MT) | 0.501358% | 0.681856% | 0.153000% | 1.336214% |

It's the Education Tax, Not the City's Own Rate
Look at the three columns separately and the story changes. The City's own portion for commercial property (0.600937%) is about 1.52 times the residential City portion — a real gap, but not a dramatic one, and it directly reflects the legislated 2026 tax ratio of 1.516977 for the commercial class. The Region of Peel portion follows the same 1.52x ratio.
The outlier is the education line. Ontario's Ministry of Finance sets a single province-wide Business Education Tax (BET) rate for commercial and industrial properties under Ontario Regulation 400/98 — separate from, and far higher than, the residential education rate. In Mississauga's 2026 schedule, that's 0.880% for commercial and industrial property against 0.153% for residential — a 5.75x gap that the City and Region have no control over.
Same Assessed Value, Different Tax Bill
To make the multiplier concrete, here's the same hypothetical assessed value taxed under each rate. Real commercial and residential assessments differ widely in scale, so treat this as an illustration of the rate gap, not a prediction of your specific bill.
| Assessed Value | Residential Tax (1.087901%) | Commercial Tax (2.298223%) | Industrial Tax (2.389885%) |
|---|---|---|---|
| $500,000 | $5,440 | $11,491 | $11,949 |
| $1,000,000 | $10,879 | $22,982 | $23,899 |
| $2,000,000 | $21,758 | $45,964 | $47,798 |

The Rate Behind Your TMI or NNN Charges
Most Mississauga small business owners in retail plazas, office space, or industrial units don't own their building — they lease under a net or triple-net (NNN) structure, where the landlord passes through property tax as part of TMI (Taxes, Maintenance, Insurance) charges, typically billed per square foot on top of base rent. That means the 2.298223% commercial rate (or 2.389885% industrial rate) flows directly into your occupancy cost even though your name never appears on a tax bill.
When comparing lease offers, ask specifically for the current TMI rate per square foot and how much of it is the property tax component versus maintenance and insurance — landlords in older strip plazas with lower assessed values can sometimes offer a materially lower effective tax passthrough than a newer building with a higher CVA, even at the same posted rate.
Mississauga Hasn't Adopted the Optional Small Business Subclass
Ontario created an optional Small Business Property Tax Subclass in 2020, letting municipalities apply a reduced rate (commonly a 15–20% cut, matched by an equivalent provincial education tax reduction) to eligible small commercial properties under a set assessed-value threshold. Toronto and Ottawa have both adopted versions of it.
Mississauga's By-law 0061-2026 Schedule A contains no small business subclass rate code alongside its commercial, industrial, and farm-related subclasses — meaning eligible small businesses here don't currently get the discount that a comparable Toronto or Ottawa small business would. Whether the City considers adopting the subclass is a Council-level decision; if this matters to your business, it's a reasonable thing to raise with your Ward Councillor ahead of the next budget cycle.
Assessments Are Still Frozen at 2016 Values
Every property class in Ontario, commercial and industrial included, is still assessed at its January 1, 2016 value — the province has postponed the province-wide reassessment update through the current cycle, with no confirmed resumption date as of 2026. For a Mississauga business, that has cut both ways: industrial land values in parts of the GTA have risen sharply since 2016 on the back of logistics and warehousing demand, meaning many industrial ratepayers are taxed on assessments well below current market value. Office and some retail categories, by contrast, may be assessed above what a 2026 buyer would actually pay for the same space, given the post-2020 shift in demand for office and traditional retail footprints.
The practical implication: don't assume your assessed value reflects what your property or unit would sell or lease for today in either direction. If you believe your MPAC assessment is out of line with comparable current-cycle sales, a Request for Reconsideration through AboutMyProperty is the first step, with an appeal to the Assessment Review Board as the formal route.
Confirmed vs. Estimated
Action Checklist
- Confirm your property class. Check your tax bill or MPAC notice — commercial, industrial, office building, and shopping centre classes carry different rates.
- If you lease, ask for the TMI breakdown. Get the property tax component isolated from maintenance and insurance before comparing offers.
- Check your CVA against current comparables. If your assessment looks out of step with recent sales or leases in your class, file a Request for Reconsideration with MPAC.
- Raise the small business subclass question. If a reduced rate would matter to your business, this is a Council-level advocacy point, not something MPAC or your accountant can grant.
