There needs to be a state wide sales tax. Why? Because it is the most fair tax, the easiest to collect since it is collected by businesses, AND it would allow cities to collect sales taxes on internet sales, which Alaskan cities presently cannot do. Alaska is one of FOUR (4) states in the US that are not on Amazon's list of applying sales tax to an order. I live in Bethel, and everyone buys on Amazon here, and our 6% sales tax cannot be applied due to our "wonderful" legislators in Juneau. Our sales tax collection are DOWN because of the online sales, and our small city is being hit hard from not collecting internet sales tax. 
Some do not want a sales tax - well, i would much rather pay as I go rather than a lump sum hit which an income tax is. Also, enforcing income taxes is very expensive and much less is actually collected, due to cheaters and underreporting. 
With a sales tax, groceries and pharmaceuticals are typically exempt, so the poor do not get hit for necessities.
