Information regarding an extension to file a FEDERAL tax return:
If you are not able to file your tax return by the due date, you may be able to get an automatic 4-month extension of time to file. To get the automatic extension you must file Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, by the due date for filing either your calendar or fiscal year return. Please be aware that an extension of time to file your return does not grant you any extension of time to pay your tax liability. Also, there are exceptions and not everyone qualifies for the automatic extension.

Information regarding an extension to file a STATE tax return:
You no longer have to send a written request for an extension to file your California tax return. You will automatically have an extension to file until October 15, 2002. If you file your return by October 15, 2002, the penalty for filing late will not be assessed. There is no extension for paying your tax. To avoid late payment penalties and interest you must pay the full amount of tax you owe by April 15, 2002. Use form FTB 3519, provided in the 540A and 540 booklets to make your April 15th payment. If you owe, but cannot pay your taxes by April 15th, you should still file your return on time. Although there are penalties for late payment of tax, the penalty for late filing of the return is usually higher. After your return is processed, the Franchise Tax Board will send you a bill including penalties and interest.
