How the chart is checked

Nothing in this note is estimated. When a displayed figure disagrees with the official publication, the publication wins. That rule is recorded under corrections.

Rate monitoring is not a tax calculation

This note reports how the Colorado publication is monitored. It does not calculate tax on a cart, invoice, ZIP code, or address, and it does not file a return.

Monitor Colorado

Monitoring follows the official publication. The sample report shows the shape of a change row.
