Variance is mathematical abstraction. Its square root is standard deviation. It is measured in dollars (not squared) and has applied sense.
For example, tax=10 million $, st. dev. =2 million $, then we have an interval between 8 and 12 million $, where the value will occur with the probability about 65%.
