Innisfil Property Tax: Rates, Installments, and Payment Options

Innisfil property tax for 2026 is charged at a combined residential rate of 1.239628% of your property’s assessed value, which covers the Town of Innisfil, the County of Simcoe, and the province’s education levy. The town bills you twice a year, and for 2026 the final installments are due June 29 and September 28.¹ You can pay online through your bank, by mail, in person at Town Hall, through a 24-hour drop box, or by signing up for automatic withdrawals.

How Your Bill Is Calculated

Your tax bill is your assessed value multiplied by the combined rate. The Municipal Property Assessment Corporation (MPAC) sets that value under Ontario’s Assessment Act, and when a province-wide reassessment pushes your value up, the increase is phased in over three years rather than applied all at once.²

The 1.239628% combined rate has three parts:

The Town of Innisfil portion, which pays for local roads, fire, recreation, and municipal administration.
The County of Simcoe portion, which funds paramedics, social housing, regional roads, and long-term care.
The education portion, set by the province at 0.153% for residential properties in 2026 and passed on to school boards.³

On a home assessed at $500,000, the combined rate produces about $6,198 in annual property tax. Your statement shows each of the three components separately.

When You Pay: Two Bills, Four Installments

Innisfil issues two tax bills each year, with two installments on each.

The interim bill goes out early in the year and equals 50% of what you paid the previous year. It keeps the town funded until council approves the current year’s budget. Interim installments are typically due in March and May.

The final bill follows once the budget is set, applies the new rate, and reconciles anything already paid on the interim bill. For 2026, the two final installment dates are June 29 and September 28.¹ Penalties start the day after a missed date, with no grace period built in.

How to Pay

All payments go to the Town at 2101 Innisfil Beach Road, and you’ll need your 19-digit roll number, which appears on your tax bill and on your MPAC Property Assessment Notice.⁴¹

Online banking. Add the Town of Innisfil as a payee through your bank and use the 19-digit roll number as the account. Allow two to three business days for the payment to reach the town before the due date.¹
In person at Town Hall during business hours.
Drop box at the municipal office, available 24 hours. Include the payment stub with any cheque.
By mail to the town’s address, with the stub, leaving several days for delivery.

Check the roll number carefully. A wrong digit sends your payment to another property’s account.

Pre-Authorized Payment Plans

If you’d rather not track due dates, Innisfil runs a pre-authorized payment plan that withdraws funds automatically. You can choose monthly withdrawals spread across the year or larger withdrawals timed to the installment due dates.¹

To enroll, complete the registration form from the town’s website and include a void cheque or a pre-authorized debit form from your bank. If you switch bank accounts or move, notify the finance department immediately. A failed withdrawal is treated as a missed payment and draws the same penalty as paying late.

What Happens If You Pay Late

Innisfil charges a penalty of 1.25% per month on any unpaid balance, applied on the first business day of each month until the account is cleared.¹ That works out to 15% per year. The 1.25% is the maximum allowed under Section 345 of the Municipal Act, and the town charges the full rate. Council has no authority to waive or reduce it.

Anything you pay is applied first to accumulated penalties and interest, then to the oldest outstanding tax balance.¹ Partial payments can leave you in arrears longer than you’d expect, because new penalties keep landing on top of what remains.

If taxes stay unpaid long enough, the town treasurer can register a tax arrears certificate against the property. Once that happens, the owner has either one year or 90 days, depending on the property type, to pay the full cancellation price of arrears, penalties, interest, and costs before the town can sell the property through public tender or auction.⁵ Tax sales are rare, but they are the endpoint of prolonged non-payment. Contact the finance department well before that stage. Payment arrangements made before a certificate is registered are much easier to negotiate than anything after.

Disputing Your Assessment

If you think MPAC has your property’s value too high, you can challenge it, but Ontario requires a specific sequence.

Start With a Request for Reconsideration

For residential, farm, managed forest, and conservation properties, you must first file a Request for Reconsideration with MPAC. File it online through the AboutMyProperty portal and include your evidence, such as recent comparable sales or corrections to features MPAC has on record.⁴ MPAC issues a written decision.

Then Appeal to the Assessment Review Board

If the reconsideration doesn’t settle it, you can appeal to the Assessment Review Board within 90 days of the mailing date on MPAC’s decision.⁶ The residential filing fee is $132.50 per roll number, with a $10 discount for filing electronically.⁷ The ARB is an independent tribunal, and its decision binds both you and MPAC.

Commercial and industrial properties skip the reconsideration step. The annual assessment appeal deadline is March 31, and the fee is $318 per roll number.⁶⁷ Late filings are rejected on that basis alone.

Relief for Seniors and Low-Income Persons With Disabilities

Under Section 319 of the Municipal Act, Ontario municipalities must offer property tax relief to low-income seniors and low-income persons with disabilities, and Innisfil has a program under that authority. To qualify you generally need to be at least 65 or receiving Ontario Disability Support Program benefits, and the property must be your principal residence.

The program reduces your tax bill rather than eliminating it. Applications must be filed by the town’s annual deadline, typically in the fall, to apply to the current tax year. Current income thresholds aren’t published on the town’s general tax page, so contact the finance department at Town Hall for the limits and an application form. The town may ask for documentation of income and eligibility.

Reduced Rates for Farm and Managed Forest Land

Eligible farmland is taxed at 25% of the residential municipal rate under Ontario’s Farm Property Class Tax Rate Program.⁸ For 2026, that puts qualifying farmland at roughly 0.31% instead of the full 1.24%. The reduction applies only to the farmed land. The house and its immediate lot remain at the full residential rate.

The Managed Forest Tax Incentive Program offers the same 25% reduction for enrolled forested land, and enrollment requires an approved managed forest plan.⁹ Farm eligibility is administered by Agricorp, and managed forest eligibility by the Ontario Ministry of Natural Resources. Both require periodic renewals and compliance checks.

If You’re a Non-Resident Buyer

Innisfil’s property tax bill isn’t the only tax that lands on foreign buyers. Ontario’s Non-Resident Speculation Tax adds 25% of the purchase price at closing for individuals who are not Canadian citizens or permanent residents, foreign corporations, and certain trustees, on top of regular land transfer tax.¹⁰ On a $500,000 Innisfil home, that’s $125,000.

Non-resident owners may also owe the federal Underused Housing Tax, a 1% annual tax on the value of vacant or underused residential property in Canada, with its own separate return and deadlines.¹¹ These are separate obligations from the town tax bill and carry their own penalties for non-compliance.
