Also good to know: Estate tax (Form 706) is due 9 months after the date of death, with a 6-month extension available. An extension gives you more time to file, not more time to pay. Any tax owed is still due by the original deadline. Fiscal-year filers and June-30 C corporations follow different dates. Not sure which apply to you? Let's talk.
