Property tax in Halton Hills is a single bill that funds three governments: the Town, the Region of Halton, and the Province of Ontario for education. For 2026, the combined bill is expected to rise about 5.11 percent over the prior year, driven by a 3.56 percent increase on the Town’s portion and a 4.64 percent increase on the Region’s share, with the education rate held flat.1Town of Halton Hills. Halton Hills Finalizes 2026 Budget What you actually owe depends on your property’s assessed value multiplied by the combined rate for your property class.
How Your Bill Is Calculated
Two numbers produce your tax bill: an assessed value set by the Municipal Property Assessment Corporation (MPAC), and a combined tax rate set locally each year. MPAC values every property in Ontario based on location, lot size, building size, age, renovations, and sales of comparable nearby homes, under the framework of the Assessment Act.2Ontario.ca. Assessment Act, R.S.O. 1990, c. A.31
One quirk matters for every Halton Hills homeowner right now: assessments for the 2026 tax year are still based on fully phased-in January 1, 2016 values, because Ontario has repeatedly postponed its province-wide reassessment.3MPAC. Notices and Notifications If your home has appreciated since 2016, your assessed value likely sits below current market. When the province lifts the freeze, expect assessed values, and bills, to jump.
Your Property Assessment Notice from MPAC shows your assessed value and a 19-digit roll number that identifies your parcel.4Municipal Property Assessment Corporation. AboutMyProperty Keep it. You’ll need that roll number to set up online payments, access the Town’s tax portal, and file any assessment challenge.
To estimate your bill, multiply your assessed value by the combined residential rate for the current year. A $500,000 home at a combined rate of 0.008 would owe $4,000 for the year. Rates vary by property class: residential, commercial, and industrial each carry different combined rates, and the Town publishes the finalized figures on its tax rates page once budgets pass.5Town of Halton Hills.

How and When to Pay
Halton Hills collects taxes in four installments. Interim bills, based on the previous year’s rates, come due in February and April. Final bills, using the current year’s rates, come due in June and September. You have several ways to pay:7Town of Halton Hills. Property Tax Payment Options
- Online banking, by adding the Town as a payee and using your 19-digit roll number as the account. Banks take a few business days to process, so submit early.
- Pre-authorized withdrawal. A monthly plan spreads payments across ten months from January through October. A due-date plan withdraws on each of the four installment dates. Both require the account to be current and a void cheque with the application.8Town of Halton Hills. Pre-Authorized Tax Payment Plan Application
- Cheque by mail to the municipal office listed on your bill.
- Credit card, only through a third-party service. The Town does not accept credit cards directly, and the service charges a convenience fee the Town is not responsible for.
The monthly plan is worth considering if you’d rather spread the cost than face four larger payments. After paying by any method, confirm the payment posted through the online portal or by calling the treasury department.
What Happens If You Pay Late
Halton Hills charges a 1.25 percent penalty on any unpaid balance, applied on the first day you’re late and again on the first of each month the balance remains outstanding through December 31.9Town of Halton Hills. By-law No. 2025-0098 – A By-law to Levy 2026 Interim Taxes and Establish Penalty and Interest Rates On a $2,000 overdue installment, that’s $25 the first month and $25 again each following month, calculated on the growing balance.
Longer-term arrears carry a much bigger consequence. Under Ontario’s Municipal Act, if any tax arrears remain unpaid on January 1 of the second year after the taxes originally became due, the municipal treasurer can register a tax arrears certificate against the property’s title.10Ontario.ca. Municipal Act, 2001, S.O. 2001, c. 25 Once that certificate is registered, you have one year to pay the full cancellation price. Otherwise the municipality can sell the property at public auction.
Relief Programs If You Qualify
The Town and the Region run separate programs with different rules and deadlines. Read both before deciding which applies.
Town Seniors Tax Grant
The Town offers a $500 grant to eligible low-income seniors. To qualify, you or your spouse must be at least 65, receive the federal Guaranteed Income Supplement, occupy a residential property in Halton Hills, and have been the assessed owner for at least one year before applying. If you received the grant previously, the Town mails a new application each June, and it must be returned by October 1.11Town of Halton Hills. Tax Relief Programs and Rebates
Regional Low-Income Tax Deferral
The Region of Halton runs a deferral program for low-income seniors and low-income persons with disabilities. A deferral postpones collection; it does not reduce what you owe. Seniors qualify at 65 or older with combined family income of no more than $43,200 per year. Persons with disabilities qualify if they receive benefits through a program such as the Ontario Disability Support Program, Canada Pension Plan Disability, or a private insurer plan, and combined family income is at or below $43,200.12Halton Region. Low-Income Seniors and Low-Income Persons with Disabilities Property Tax Deferral Program
Applications are due within 45 days after the final property tax bill is mailed, not by the end of the calendar year. Miss the window and you wait until the next tax year.
Challenging Your Assessment
If you think MPAC’s value is wrong, you cannot go straight to a tribunal. You have to follow a two-step process.
Step One: Request for Reconsideration
File a Request for Reconsideration (RfR) with MPAC. For residential properties, the deadline is printed on your Property Assessment Notice and is generally 90 days from the mailing date.13Tribunals Ontario. ARB Info Sheet – Request for Reconsideration MPAC reviews the property data, may inspect the home, and issues a decision. Factual errors, like wrong square footage or a missed condition adjustment, often get resolved here.
Step Two: Assessment Review Board
If the RfR decision doesn’t resolve the issue, or MPAC doesn’t respond by its statutory deadline, you can appeal to the Assessment Review Board. The filing fee for a residential property is $132.50 per roll number.14Tribunals Ontario. Filing an Appeal The ARB is an independent tribunal that can order MPAC to change your assessment. Comparable sales data for similar nearby properties is typically what carries an appeal.
Tax Certificates for Sellers
If you’re selling, your real estate lawyer will need a tax certificate confirming the property’s tax status and any outstanding balance. Halton Hills charges $65 for a standard certificate and $75 for a rush request. Order by mailing a written request with payment and the legal description or municipal address of the property.5Town of Halton Hills.
