The taxes paid on this largess is insignificant, to say the least:
One to five percent. This after recently pounding the oil and gas industry at 25%.
And few Alaskan residents are interested or capable of harvesting and processing their own oil and gas.
There are taxes specific to fishermen and fish processors which are not included in you source. This implies that fishermen pay a 1-5% tax rate. This is incorrect.
Enhancement taxes= 2-3% of gross landings (that's right, tax is on the gross...) (these monies directly fund hatcheries, fisheries management, and scientific research on salmon), Port and City assessments on fish landings= 2-3%, Alaska Seafood Marketing Assessment= 0.5%,
This bumps the average fisherman's tax bill well over the Alaska State corporate maximum from your link.
