Updated Checked by the Tax-Services.ca editorial team How we check
Municipal business taxes, for most Canadian businesses, show up as a property levy on the space you use, not as a separate tax on your profit. In Toronto, for example, the city raises the budgets of its more than 85 Business Improvement Areas through a special property tax levy on commercial and industrial properties in each area, and non-residential tenants contribute too.
What do municipal business taxes look like in your books?
Two things usually land in the accounts. One is the ordinary property tax on the building. The other is a local levy on top, such as a BIA charge. If you own the premises, both come on your own tax bill. If you rent, they often reach you through the lease, sometimes as a line in additional rent. We can’t tell you how your lease works. Read the clause on taxes and operating costs, because it decides who pays and how you get billed.
We went looking for a separate city tax on business income in the big cities and didn’t find one on the official pages we checked. Municipal rules vary, so we won’t claim none exists where you are. Ask your city’s finance office, or check its tax pages.
How does the tax get worked out?
The City of Toronto describes the bill as the assessed value of the property multiplied by the tax rates: the city rate, the education rate set by Ontario, and a city building fund levy where it applies. A BIA levy is added when the property sits inside a BIA boundary. The exact rates change every year and differ from city to city. We don’t quote a rate here. Take it off your current bill or the city’s rates page.
| Piece of the bill | Where to find it |
|---|---|
| Assessed value | Your assessment notice |
| City and education rates | The city’s yearly rates page |
| BIA levy | A separate line on the bill, if the property is in a BIA |
| Who pays it | Owner, or tenant under the lease |
What does a bill of $20,000 mean for your return?
Use a round example, not a real city rate. A property assessed at $1,000,000 and taxed at a combined 2.00% costs $20,000 a year, which the property tax calculator shows as $1,666.67 a month. If you only own it for 8 months of the year, your share is $13,333.33.
The CRA says you can generally deduct any reasonable current expense you incur to earn business income. For a rental property, it lets you deduct a proportional share of property taxes. That’s the general rule. How much of your bill counts depends on how the space is used, so check the CRA guide for your type of business.
The saving from that deduction is less than people think. Take the $20,000. In Ontario, at the calendar 2026 small business blend of 11.696% combined from our corporate tax calculator, that deduction lowers corporate tax by about $2,339, assuming all of it is deductible and the company keeps the small business rate. The other $17,661 is real cost.
How should you book it?
Record property tax and BIA levy on separate lines. It costs nothing and it means you can see the BIA charge year over year. Accrue the amount monthly rather than waiting for instalment dates, so your monthly profit is not jumpy. The profit margin calculator is a quick way to see how much location costs eat into a margin.
A few traps are worth a look. Mixing a refundable deposit with a tax payment. Forgetting that a year-end assessment change can produce a supplementary bill. Assuming your landlord’s pass-through equals the actual tax. Ask for the bill behind any charge that looks high.
If you operate in several cities, keep each location’s levy in its own cost centre. One city’s BIA charge tells you little about another’s.
Where the numbers come from
The BIA facts come from the City of Toronto pages on Business Improvement Areas and on property tax rates. The deduction rules come from the Canada Revenue Agency business expense guidance. The $20,000 example is our own round number. The corporate tax comes from our calculator for a calendar 2026 year, and the Ontario small business rate in it is a derived blend.
