California short $1 billion in tax revenue, Housing Bust Might be Cause

From the AP: California short $1 billion in tax revenue, controller says

"Tax payments are down about $1 billion, and we don't yet have the source of that decrease," said Controller John Chiang, holding a news conference at the state's tax-collection center, where 2006 tax returns have begun to trickle in.

Chiang speculated that the state's slumping housing market might be a cause of the revenue decline.
