Property Taxes

The Town of Newmarket's primary funding source is property tax which is divided between the Town of Newmarket, York Region and the school boards. Property taxes enable the Town to provide the high quality of municipal programs and services that Newmarket residents are accustomed to.

Newmarket determines your property taxes by multiplying your current value assessment (determined by the MPAC) by the Town's tax rate, the Region of York's tax rate and the provincial education tax rate.

If you have questions about your property assessment, please contact the Municipal Property Assessment Corporation (MPAC).

Property tax payment options
