On their website, the State of California Franchise Tax Board state that you should expect your refund within 8 weeks if you mailed your tax return, or within 2 weeks if you e-filed your return (www.ftb.ca.gov/individuals/faq/how_long_to_receive_refund.sh ).
You should be able to check the status of your refund by visiting the following page - www.ftb.ca.gov/online/refund/index.asp Alternatively, if you want to check the status of your California personal income tax refund for previous years, or you still have further questions, you can call the California Franchise Tax Board on 800.852.5711 during business hours (7am to 5pm on weekdays, except bank holidays).
If you are yet to file your tax return and would like to ensure a prompt
refund if you are entitled to one, then you should try to complete your tax return online. Visit the Franchise Tax Board website (www.ftb.ca.gov/individuals/index.shtml ) for information on whether you are able to do this.
If you are awaiting a refund on your federal income tax rather than your state tax, then you would need to get in contact with the Internal Revenue Service instead. You can visit their website at www.irs.gov/ and use the 'Where's My Refund?' service (sa2.www4.irs.gov/irfof/lang/en/irfofgetstatus.jsp )
If you are looking for information on taxation in states other than California, then a clickable map of state tax administrations is available on the website of the Federation of Tax Administrators (www.taxadmin.org/fta/link/forms.html ).
