OLYMPIA, Wash. (AP) - Senate Democrats have introduced a bill that would impose a 1 percent income tax on people making more than $500,000 a year. 

The bill sponsored by Sen. Jeanne Kohl-Welles, D-Seattle, was unveiled Wednesday. It comes shortly after Senate Majority Leader Lisa Brown, D-Spokane, began pondering the possibility of a state income tax on her blog.

On Tuesday, Brown noted that New York is considering a similar measure. Brown wrote that New York's income tax plan would be "a fair and stable way" of dealing with declining state revenue.

Kohl-Welles has introduced an income tax plan in prior legislative sessions, but the bill has never moved very far. In the past, courts have said income taxes are unconstitutional in
Washington.
