Federal Extension Help!

[applesandoranges2]

I am trying to file an extension. But I owe federal taxes ($500) and am expecting a refund for California ($100).  With my extension, do I need to submit $500 or $400?

For your federal extension, you should pay $500.  Your California overpayment cannot be used to decrease the balance on your federal extension.  You'll receive the refund when you file your California return.
