Today on the Hill. The House and the Senate will go to conference over the multi-year highway bill. The House Budget Committee holds a hearing on the biennial budget process. Witnesses include Representative Reid Ribble (R) of Wisconsin, Representative David Price (D) of North Carolina, Philip Joyce of the University of Maryland, Rudy Penner of the Urban Institute, and Alice Rivlin of the Brookings Institution. Still no tax deal in Pennsylvania. The state Senate will vote next week on a measure that would nix $14 billion in school property taxes and levy higher sales and state income taxes.

Will Massachusetts vote on a millionaire’s tax? Advocacy group Raise Up Massachusetts wants a constitutional amendment to add a 4 percent tax on income over $1 million.

The proposal couldn’t be on a ballot until 2018 at the earliest. A new tax to spur housing development? In Saudi Arabia, residents often raise land prices by trading property.

The king needs to approve the regulation. Interested in subscribing to the Daily Deduction, the Urban-Brookings Tax Policy Center summary of the day’s tax news?
