To imagine what such a large soak-the-rich income tax would do to Washington, we need only examine how states with the highest income-tax rates perform relative to their zero-income tax counterparts. Comparing the nine states with the highest tax rates on earned income to the nine states with no income tax shows how high tax rates weaken economic performance.
In the past decade, the nine states with the highest personal income tax rates have seen gross state product increase by 59.8%, personal income grow by 51%, and population increase by 6.1%. The nine states with no personal income tax have seen gross state product increase by 86.3%, personal income grow by 64.1%, and population increase by 15.5%.
. . .
Each and every state that introduced an income tax saw its share of total U.S. output decline. Some of the states, like Michigan, Pennsylvania and Ohio, have become fiscal basket cases. As the nearby chart shows, even West Virginia, which was poor to begin with, got relatively poorer after adopting a state income tax.
. . .
The states that have high income tax rates or have adopted a state income tax over the past 50 years haven't even gotten the money they hoped for. They haven't avoided budget crises, nor have they provided better lives for the poor. The ongoing financial travails of California, New Jersey, Ohio, Michigan and New York are cases in point.
Over the past decade, the nine states with the highest tax rates have experienced tax revenue growth of 74%—a full 22% less than the states with no income tax. Washington state has done better than the average of the nine no-tax states. Why on earth would it want to introduce a state income tax when it means less money for state coffers?

More evidence that taxing anyone is taxing everyone
Washington state is talking about imposing a new tax on high income earners. I argued in an earlier post that a tax on anyone is a tax on everyone. Art Laffer underscores my point by explaining what has happened in other states that have imposed such a "tax on the rich":
