Calculate Your Property Tax
Business Properties
Step 1
Determine the market value, as provided by the Montgomery County Auditor's Office. This is called the appraised value. You may also call 937-225-4326.
Step 2
Multiply the appraised value by 35% to get the taxable value, known as the assessed value.
Example: $100,000 appraised value X .35 = $35,000 assessed value
Step 3
Divide the assessed value by 1,000 to get the cost per mill (mill is defined as 1/1,000).
Example: $35000 ÷ 1,000 = $35 per mill cost.
Step 4
Multiply the per mill cost times the effective millage rate, which is 18.249179 for nonresidential property in unincorporated Washington Township and 9.993727 for the incorporated area (city).
Unincorporated Example: $35 X 18.249119 = $638.72
Incorporated Example: $35 X 9.993727 = $349.78
