The market value, assessed value and taxable value of your house are often nothing alike. The market value is what your house would sell for in the current market. The assessed value is what your county tax assessor reports the house is worth for purposes of calculating your property tax bill. Taxable value is the figure you actually pay tax on.
Even if your bill is not affected by the market value of your property, it can still be affected by changes in the tax rate for any component of the property tax. Tax authorities can increase your bill by increasing the assessed value of your property and/or by increasing the tax rate.
