Here is another example of why an income tax is needed in Alaska. An Alaska Native Corporation now has this contract. They will distribute its profits  as dividends, from this project to Alaskans. Those dividends will not be taxed by Alaska. Those receiving the dividends would receive nothing if the State of Alaska did not provide, roads and airports to these jobs.   Meanwhile the workers, including out of state residents will be leaving Alaska and paying nothing to the coffers they rely on to provide the infrastructure to have a job in Alaska. 

If Feb of this year Gov. Walker released a report regarding out-of-state workers. http://live.laborstats.alaska.gov/reshire/nonres.pdf those who continue to doubt the 16% of Alaskan jobs are held by non-residents need to read just the two page introduction.  There you can see that $ 2.7  billion in wages left Alaska tax free in 2015.  

You can dispute the income tax idea all day. You can not dispute the nontaxed wages leaving Alaska.
