Updated. See below. Again, Aug 12.
There’s been some debate going back and forth recently on how many Washington State taxpayers will be affected by the proposed income tax. The two sides have done a good job of providing the source data (you can follow their links), but the debate’s been inconclusive because:
1. Single filers would pay the tax above $200K in adjusted gross income, and married filers pay above $400K in AGI.
2. We (I) don’t really know how many filers make more than $400k
Curious as always, I decided to run the numbers assuming that 30% of >$200K filers make more than $400K (probably a generous assumption). I’m also using the percentages provided by EOI in the debate: 85% of >$200K filers file joint returns.
Here’s the arithmetic that results (and here’s the spreadsheet [XLS]):

So, with the property-tax and business excise-tax reductions in 1098:
59% of >$200K filers with business income will have lower taxes.
80% of >$200K filers will have lower taxes or no change. (Anyone care to break this out?)
95.8% of filers with business income will have lower taxes or no change.
99.35% of filers will have lower taxes or no change.
Update: It turns out my 30% estimate was remarkably accurate — but not generous as I suggested. The actual number is closer to 33%. I’ve updated the spreadsheet, including the source link (XLS) for these calcs.

Update August 12:
The state Office of Financial Management estimates that 38,400 filers will be affected by the income tax — significantly higher than the 22,000 I estimated.
But still: 99% of Washington’s 3.4 million filers will see lower taxes or no effect under this initiative. The lower taxes will be primarily on small businesses.
