Property Tax Postponement for Senior Citizens, Blind, or Disabled Persons
On February 20, 2009, the Governor signed Chapter 4, Statutes of 2009, which immediately suspends the Senior Citizens' Property Tax Deferral Program. This legislation prohibits the filing of claims for property tax postponement and prohibits the Controller for accepting claims for property tax postponement pending modification or repeal of this new law. However, the Controller's Office will continue processing claims postmarked pior to February 20, 2009. For the most current information on the PTP program please visit the State Controller website at sco.ca.gov.
