Newmarket’s 2026 residential property tax rate is 0.919045% of your MPAC assessment, up 3.07% from 2025. The Town’s average home, assessed at $711,000, pays about $6,534 a year. Taxes are due in six instalments; in 2026 they fell on February 25, March 25, April 27, July 24, August 25 and September 25.
This guide is for Newmarket homeowners and for buyers comparing what a home there costs to carry. You will get the 2026 tax rate, what the average home pays, Newmarket’s six instalment dates, how to set up online payments with the right roll number, and the seniors deferral program. The numbers come from the Town of Newmarket, York Region and TRREB sales data.
What is the Newmarket property tax rate for 2026?
Newmarket’s 2026 residential tax rate is 0.919045% of your MPAC assessment, or $919.05 for every $100,000 of assessed value. It has three parts:
| Residential rate | 2025 | 2026 | Change |
|---|---|---|---|
| Town of Newmarket | 0.362786% | 0.373633% | +2.99% |
| York Region | 0.375863% | 0.392412% | +4.40% |
| Education (set by the Province) | 0.153000% | 0.153000% | 0.00% |
| Total | 0.891649% | 0.919045% | +3.07% |
Source: Town of Newmarket, 2025 and 2026 Schedule of Tax Rates (Schedule A). Percentage changes are my calculations.
The Town works out your bill by multiplying your MPAC assessment by each of these three rates. York Region’s share is slightly larger than the Town’s.
How much property tax will I pay on a Newmarket home?
Multiply your assessment by 0.919045%. Here is what common assessments pay at the 2026 rate:
| MPAC assessment | 2026 tax per year | Per month | Change vs 2025 |
|---|---|---|---|
| $500,000 | $4,595 | $383 | +$137 |
| $600,000 | $5,514 | $460 | +$164 |
| $711,000 (Town average home) | $6,534 | $545 | +$195 |
| $800,000 | $7,352 | $613 | +$219 |
| $1,000,000 | $9,190 | $766 | +$274 |

What does the average Newmarket home pay?
The Town bases its budget examples on an average home assessed at $711,000. At the 2026 rate, that home pays about $6,534 a year, or $545 a month. The Town notes that the $711,000 is based on 2016 market values, which is why it is well below what Newmarket homes sell for today. My guide to Ontario’s 2016 assessments explains why the values are still frozen.
How much did Newmarket property taxes go up in 2026?
The total residential rate rose 3.07% by my calculation, so a home with an unchanged assessment paid about 3.07% more. Two budgets drove it:
- Town of Newmarket: Council approved a 2.99% increase on the Town’s portion on December 8, 2025. The Town put that at about $78 a year, or $6.50 a month, on the average home. The Town says its levy remains one of the lowest in York Region.
- York Region: the Region’s 2026 budget includes a 3.28% tax levy increase plus a separate 1% Rapid Transit and Infrastructure levy that continues from earlier years. York Region said together they add about $129 to the average residential tax bill across the Region. The budget adds 150 new York Regional Police positions in 2026.
The education rate did not change. Because the Region’s rate rose faster than the Town’s, the Region’s share of your bill grew in 2026.
When are Newmarket property taxes due in 2027?
Newmarket is different from most GTA towns: it splits the year into six instalments, three on each bill. Here are the 2026 dates:
| Bill | 2026 due dates |
|---|---|
| Interim | Wednesday, February 25; Wednesday, March 25; Monday, April 27 |
| Final (issued in June) | Friday, July 24; Tuesday, August 25; Friday, September 25 |
| Supplementary or omitted (if MPAC issues a change notice) | Billed in late fall |
Source: Town of Newmarket, Property Taxes page (2026 due dates).
The Town says the dates shift slightly each year to avoid weekends, so expect 2027 instalments around the 25th of February, March, April, July, August and September, and confirm them on your bills. If a bill does not arrive, call the Town before the due date. The Town is clear that not receiving a bill does not excuse you from paying or from interest charges.
When will Newmarket set its 2027 tax rate?
Expect the 2027 rates by mid-2027. In the 2026 cycle, Newmarket Council approved its budget on December 8, 2025, the Region set its own budget, and final bills with the new rates went out in June 2026. Until then, the first half of the year’s payments is based on last year’s taxes. Until the 2027 final bill arrives, plan with the 2026 rate and leave room for an increase: each 1% on the total bill is about $65 a year on the average $711,000 home.

How do I pay Newmarket property tax online?
Add Newmarket Taxes as a payee in your banking app. The tricky part is the account number. The Town asks for a 19-digit version of your roll number:
- Start with the roll number printed on your tax bill.
- Add the digits 19 to the beginning.
- Remove the last two digits.
The Town’s own example turns 48-12-3-456-78910-0000-06 into 1948-123-456-78910-0000. Payments take three to five business days to reach the Town, so do not pay on the due date.
Other ways to pay:
- In person at the Municipal Offices at 395 Mulock Drive, or at the customer service kiosks at the Magna Centre and Ray Twinney Recreation Complex. Cheque or debit only; cash and credit cards are not accepted for property tax at Town facilities.
- By mail to the Town of Newmarket at 395 Mulock Drive.
- Post-dated cheques in the after-hours drop box at the Municipal Offices, collected the next business day.
- Credit card through a third-party online service, which charges its own fee and also needs three to five business days.
Newmarket has also launched an online property tax portal where you can see your balance and print statements and receipts. You need your customer number, roll number and balance from a recent bill to link your property.
Can I pay Newmarket property tax monthly?
Yes. The Town offers three pre-authorized plans:
- Regular due dates: six withdrawals on the instalment dates.
- 15th of the month: ten withdrawals, February to November.
- Last business day of the month: ten withdrawals, February to November.
On the ten-payment plans, the February to June draws are last year’s taxes divided by ten. Once the new rate is set, the rest of the year’s balance is spread over July to November, so those payments usually rise. Your account must be paid in full to join, and changes need ten business days’ notice.
What is the interest charge on late Newmarket property tax?
Newmarket charges 1.25% interest per month on unpaid taxes, added on the first day of each calendar month the default continues. That is about 15% a year. A returned pre-authorized payment also brings a service fee and late charges, even if you replace it, and you must pay the missed amount separately.
If you sell a Newmarket home and buy another, your pre-authorized plan does not move with you. You must cancel the old plan and apply again for the new property. If you only update your bank payee and forget the plan, you can end up paying the wrong account while interest builds on the new one.
Can seniors defer property tax in Newmarket?
Yes. The Town offers a property tax deferral that lets eligible owners put off the year’s tax increase, not the whole bill:
- Seniors: 65 or older, and you or your spouse are eligible for or receive the Guaranteed Income Supplement.
- Low-income people with disabilities: receiving ODSP or GAINS disability benefits, with income of $23,000 or less for a single person or $40,000 or less for a family.
- The home must be your principal residence on January 1 of the year, and you must apply every year by September 30.
- Deferred plus unpaid taxes cannot exceed 75% of the home’s assessed value, and deferred taxes are repaid when the home is sold or transferred, except to a spouse.

Is Newmarket property tax higher than Aurora?
Yes, slightly. Both pay the same York Region and education rates, so the gap is the local share:
| 2026 residential rate | Newmarket | Aurora |
|---|---|---|
| Local municipality | 0.373633% | 0.328541% |
| York Region | 0.392412% | 0.392412% |
| Education | 0.153000% | 0.153000% |
| Total | 0.919045% | 0.873953% |
| Tax on a $711,000 assessment | About $6,534 | About $6,214 |
Source: Town of Newmarket and Town of Aurora 2026 tax rate schedules. Dollar amounts are my calculations.
The difference is about $320 a year on a $711,000 assessment. For most buyers, price and commute matter more; my Newmarket vs Aurora comparison covers both. Here is what Newmarket homes sold for this year:
| Newmarket home type | Median sold price, Jan to Oct 2026 | Change vs same period 2025 |
|---|---|---|
| Detached | $1,070,000 | -10.1% |
| Semi-detached | $825,000 | -7.6% |
| Freehold townhouse | $827,000 | -8.1% |
| Condo townhouse | $680,000 | -6.2% |
| Condo apartment | $490,000 | -12.8% |
Source: TRREB MLS data via REALM, January to October 2026 vs the same period of 2025. Town-wide medians.
The Town says it keeps its levy about 10% below the GTA average in taxes per person, which helps buyers who are stretching to get into a detached home. But do not estimate taxes from the list price. A $1,070,000 house multiplied by the rate suggests about $9,800, while its real bill depends on a 2016 assessment that is usually much lower. I always ask for the seller’s last final bill. For owners, the 15th-of-the-month plan is the easiest way to handle six due dates, as long as you expect the July payment to jump.
What to do next
- Multiply the assessment on your last bill by 0.919045% and divide by 12 for a monthly figure.
- Convert your roll number to the 19-digit format and check your online banking payee.
- Put the six 2027 due dates in your calendar as soon as the interim bill arrives.
- If you are 65 or older and receive the GIS, apply for the deferral before September 30.
- Check what your home would sell for in my Newmarket and Aurora home value guide.

Use a 19-digit version of your roll number. Add 19 to the start of the roll number on your Newmarket tax bill and remove the last two digits. The Town’s example turns 48-12-3-456-78910-0000-06 into 1948-123-456-78910-0000. Add Newmarket Taxes as the payee, and allow three to five business days.

Not at Town facilities. Newmarket accepts only cheque or debit in person, and no cash or credit cards. You can pay by credit card online through a third-party service, which charges its own fee and takes three to five business days to reach the Town, so pay early to avoid interest.
What is the penalty for late property tax in Newmarket?
Newmarket charges 1.25% interest per month on unpaid property taxes, added on the first day of each calendar month the default continues. That works out to about 15% a year. Not receiving a bill does not excuse late payment, so call the Town before the due date if a bill is missing.

Yes. Newmarket offers ten monthly pre-authorized withdrawals from February to November, on either the 15th or the last business day of each month, or six withdrawals on the regular due dates. The first five monthly payments are based on last year’s taxes, so the July to November payments usually rise.
Does Newmarket have a property tax deferral for seniors?
Yes. Newmarket lets owners 65 or older who receive or qualify for the Guaranteed Income Supplement defer the year’s tax increase. Low-income owners with disabilities on ODSP or GAINS can also qualify, within income limits. You must apply every year by September 30, and deferred taxes are repaid when the home is sold or transferred.
Are property taxes higher in Newmarket or Aurora?
Newmarket’s are slightly higher. Its 2026 residential rate is 0.919045%, compared with 0.873953% in Aurora. Both pay the same York Region and education rates, so the gap is the local share. On a $711,000 assessment, that is about $6,534 a year in Newmarket and $6,214 in Aurora.
