In our area, taxes are based on the assessed valuation of the real estate, and the taxing rates of the taxing bodies in which the real estate exists, and the amount of mega taxed industrial and commercial entities in the taxing district.
We do not live within a municipality, so we do not pay taxes for city infrastructure. Our only taxing districts are the local junior college, fire department, library district, township road, township, and local K-12 school district.
We have a 4,000 sf walkout basement home, that the county assessed at a fair cash value of $500,750. (luckily their assessment is only for the 2,000 main level.)
Tax calculation is 1/3 fair cash value ($166,900 for us) minus $6k owner occupied exemption minus $5k senior citizen exemption to arrive at a net taxable value of $155,900. The sum of the tax rates of the taxing bodies is 5.34894 ( per $100 of net taxable value)
So our tax bill for last year was $8339. (5.34894 x $155,900 / 100). School district tax itself was $5290.
So we can get increases by 2 different ways. 1 is the yearly reassessment of home value. 2 is the increase in tax rates.
So we pay 1.67% of assessed value. We are probably lower than most since we have a highly assessed and taxed nuclear power plant in our area.
I looked up taxes for a house in a nearby town. Assessed value of $540,120. Tax is $14,305 or 2.7% of assessed value.
