Will a lower assessment always reduce my property tax bill?
A lower assessment is the most powerful lever, but the final bill also depends on tax rates, local levies, and the state equalization factor (multiplier). Lowering the assessed value reduces the taxable base and limits the multiplier's impact, so even if rates rise your bill is lower than it would have been.
