Time is running out for those who want to claim a state tax rebate for a special assessment charged on property insurance bills in Louisiana in 2008. The annual assessment has been made since 2006 to pay off bonds issued to keep Louisiana Citizens Property Insurance Corp. - the state's so-called insurer of last resort - solvent after the many claims that followed hurricanes Katrina and Rita. The deadline for claiming state tax rebates for the 2008 assessment is Dec. 31. A news release from state Insurance Commissioner Jim Donelon says 52 percent of the $100 million in Citizens assessments for 2008 remains unclaimed. Policy holders can also visit www.revenue.louisiana.gov and follow links to a web application to help people claim their rebates if they have not yet done so.
