State sales tax
No state tax, set by locality
Alaska charges no state sales tax at all, one of only five states with none. Local boroughs and cities are free to set their own local option tax instead, and roughly 100 to 148 of them do, some stacking a city rate on top of a borough rate with no confirmed statewide cap on how high the combined figure can run. Anchorage and Fairbanks add nothing extra, Juneau adds 5%, and a combined rate can reach close to 7.85% in a place like Homer. Storeveu starts every Alaska store on its own borough and city rate rather than a shared state default, since there isn't one to share.
