Sales tax rate changes
Idaho sales tax rate changes
Updated October 15, 2026
Last verified October 15, 2026. That is the UTC date the Idaho State Tax Commission pages were retrieved. It is not an effective date.
US Sales Tax Rates monitors the sales tax publication Idaho State Tax Commission posts for Idaho: when the chart takes effect, how many jurisdictions changed, and what is coming next. It does not calculate tax on a sale.
Current Idaho chart
The Idaho file prints no effective date, so no effective date is given here.
Every Idaho jurisdiction on the loaded file is on the Idaho rate chart.
Changes on the current Idaho chart
No Idaho chart on file has a jurisdiction marked changed or upcoming compared with the previous file.
Upcoming Idaho changes
No upcoming Idaho rate change is on file.
What is monitored
Idaho State Tax Commission publishes the loaded sales tax chart for Idaho.
The loaded publication has no printed effective window, so this chart is not classified as in force. The loaded file is HTML.
The loaded file has 24 jurisdiction rows.
Not compared.
A refresh fails closed. When the file cannot be read, or two readings disagree, the period is blocked and no rate is filled in.
This note does not calculate tax on a sale.
Official Idaho sources
These are official Idaho State Tax Commission pages. The current rate file is found from these pages. A direct rate-file address is not linked here.
How the chart is checked
A refresh fails closed. When the file cannot be read, or two readings disagree, the period is blocked and no rate is filled in.
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 Idaho publication is monitored. It does not calculate tax on a cart, invoice, ZIP code, or address, and it does not file a return.

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