Here's another resource you need to know about -- EarnItKeepItSaveIt.org. That is a program that gives low-income workers help with tax preparation. Taxpayers making less than $49,000 in 2010 can have their taxes prepared for free.
Last year, in the Bay Area $52,000 took part in the program and was refunded $57 million. Another $18 million in earned income tax credits were claimed through the program.
