Clark County taxpayers got some improbable good news to counter their property tax bills -- they don`t have to pay them. After going through the taxpayers alphabetically to the S`s and sending out 25,000 bills, Clark County Collector Troy Tucker discovered that a computer glitch had led to billing errors. So, the county stopped billing and is now asking those who have received bills to ignore them -- for now. A new, more modern software system is apparently responsible for the errors, but the computer programmer says he will pay thousands of dollars to fix them. When the problems are corrected, Clark County will send out new bills and ask the taxpayers to pay -- this time for real.
