Estate Tax Due Dates and Extensions
field_block:node:page:body
Form M706, Estate Tax Return and payment are due nine months after a decedent's death. We allow an automatic six-month extension to file, but do not allow an extension for payment.
Exception: If the decedent died between January 1, 2009, and December 16, 2010, Form M706 was due 15 months after the date of death, or September 19, 2011 (or the extended filing date as prescribed by the Internal Revenue Service), whichever was later. This was a filing extension only.
