Rate changes. Previous is the prior printed rate. Current rate is the figure in effect, or Ended and the printed end date when the tax left the chart. Change (pts) is that move in percentage points, not a percent of the old rate. A known prior rate that left the chart moves to zero. Change effective is the official date. Verified is the time the file was retrieved.
