5 - Can I file electronically if I need to pay?
Yes. Aside from convenience, one advantage of filing electronically when you owe taxes is that you learn exactly how much you owe.
You have several payment options when you file your return electronically. You can pay your balance by using direct debit or you can pay by credit card using American Express, Discover, MasterCard or VISA. If you file electronically by April 15, you have until April 30 to make your electronic payment.
If you wish to pay by check or money order, the payment is due by April 15. You must also submit Form IND PV with your check or money order payment, if you electronically file a Form 502 or 505.
