Property Tax Estimator

How are property taxes calculated?
Taxes are calculated by applying the millage rate to every 1,000 dollars of Taxable Value (TV), then adding a 1% administration fee.

Taxable Value / 1,000 x Millage Rate x 1.01

Where do I find the property data?
A Notice of Assessment, Taxable Valuation, and Property Classification is mailed to property owners at the beginning of March each year. The property's Taxable Value and SEV may be found on the Notice of Assessment or on the online property record card here: https://www.bsaonline.com See highlighted documents below to locate the Taxable Value or SEV.
