Hi
Let me know if I have to file separate extension requests for both federal and state returns if I intend to file returns only after 15-Apr-10. (extending to meet SPT)

Also is there a form or template available for requesting extension.

Yes - you need to file separate extension request forms for federal and state. The federal form is 4868 - more info here: Extension of Time to File Your Tax Return (http://www.irs.gov/formspubs/article/0,,id=98155,00.html)

Note that the extension gives you more time to complete the tax return paperwork, but if you owe any taxes they must still be paid by April 15.
