6%
How Sales Tax Works in Idaho
Idaho imposes a statewide base sales tax rate of 6%. Idaho is a destination-based sales tax state, meaning the tax rate is determined by the buyer's delivery address.
Special district taxes: Special taxing districts (transit authorities, improvement districts, etc.) in Idaho can add additional taxes that apply within their boundaries.
Rates in Idaho are typically updated annually. Businesses should monitor rate changes regularly to maintain compliance.
Why Rates Vary by County in Idaho
The combined sales tax rate a customer pays in Idaho depends on the specific jurisdiction of the transaction. Local governments use sales tax revenue to fund essential services such as infrastructure, public safety, and education.
This means that two addresses within the same city may have different tax rates if they fall in different special taxing districts. ZIP codes are particularly unreliable for tax determination because a single ZIP code can span multiple counties or tax jurisdictions.
For businesses operating in Idaho, manually tracking these rate changes across every jurisdiction is impractical. An automated API solution ensures you always apply the correct rate at the point of sale, reducing compliance risk and audit exposure.
