It was printed in bold letters on the front of the envelope. “Open Immediately. Property Tax Notice Enclosed.” It was the annual property tax bill on my house! I remembered last year:  a jump in my tax bill of 31 percent. 

I tore open the envelope and found the page of numbers showing how my tax bill was calculated. The taxable assessed value of my home went up only 3 percent this year. Last year the increase was 35 percent. My tax rate went down by almost 5 percent. The tax bill is the assessed value times the rate. If my home value went up 3, but my tax rate went down 5, my tax bill should decrease by about 2 percent, right?  Wrong. My tax bill went up 10 percent.
