Sen. Chris Van Hollen of Maryland is expected to release the measure next week as Democratic Party lawmakers search for a sharp economic message to counter last year's Republican tax law. Under Van Hollen's proposal, workers making at or below a "living wage" - $46,000 for taxpayers filing individually, or $92,000 for married couples filing jointly - would not have to pay federal income taxes. Tens of millions of additional middle-class workers would also receive a tax cut under the proposal, but they would still have to pay taxes. The measure would be paid for by a new surcharge on millionaires that would raise roughly $1.5 trillion over the next 10 years.
