Newmarket property tax

Residential: Full Taxable (RT) rates from the Town's 2026 Schedule of Tax Rates for Taxable Property (Schedule "A").

Rates as published for the residential class. Bills can also include fixed charges, local improvement levies and utility fees that are not based on assessed value.

Newmarket's total residential rate of 0.9190% is below the 1.4606% average of the 60 Ontario municipalities we cover. A lower rate does not always mean a lower bill: tax = assessed value × rate, so cities with high home values often have lower rates.
