If you purchased your home in May 2009 and you were a first time homebuyer, then you should qualify for the Federal Tax Credit of up to $8,000. That was good for new or resale properties.
California just passed a new tax credit for people that purchase their homes between May 1, 2010 thru December 31, 2010. This is good for first time homebuyers that purchase a resale home or brand new construction. According to an article from the Associated Press, "Homebuyers can claim 5 percent of the purchase price against their California taxes, or up to $10,000".
So, in your situation, you would not qualify for the new California tax credit.
Always speak to your CPA or a tax attorney to figure out if you do in fact qualify for any tax credits.
Have a nice day!
