States with no sales tax
Five states levy no statewide sales tax. But they are not identical — and “no sales tax” does not mean “no tax at all.” The calculator below is pre-filled for Oregon.
Use this for a combined state + local rate, e.g. Los Angeles at 10.25%.
Alaska has no statewide sales tax, but many cities and boroughs charge a local sales tax. Enter your local rate as a custom rate.
The five states, compared
| State | Sales tax |
|---|---|
| Oregon | No state or local sales tax |
| Montana | No state or local sales tax |
| New Hampshire | No state or local sales tax |
| Delaware | No state or local sales tax |
| Alaska | No statewide tax — local taxes apply in many cities and boroughs |
What “no sales tax” does not mean
These states still raise revenue — typically through income tax, property tax, or other levies. And Alaska is the exception inside the group: it has no statewide rate, but more than 100 municipalities levy local sales taxes, so a purchase in Anchorage is not taxed the same way as one in a borough with a local rate. If you buy in Alaska, enter the local rate in the custom rate box.
Worked example
In Oregon
A $100 item stays $100 — no tax is added.
In California, for comparison
The same $100 item at California’s 7.25% base rate comes to $107.25. That $7.25 gap is exactly what this calculator is for.
