How can I get property tax assistance for seniors, blind or disabled persons?

The 2009/2010 state budget suspended funding for the Gonsalves-Deukmejian-Petris Senior Citizens Property Tax Assistance Law, which provides direct cash assistance. The Franchise Tax Board (FTB) will not be issuing Homeowner and Renter Assistance (HRA) Program instruction booklets and will not accept HRA claims for the 2009 claim year.
