For a married couple with wages only, Washington's millionaires tax would take 3.3% of $1.5 million, 4.95% of $2 million and 7.92% of $5 million, because the first $1 million is not taxed. Oregon takes about 9.6% to 9.8%, California 10.0% to 12.3% and Massachusetts 6.0% to 8.1%. Washington is lowest of the four at each level.
