Can I file another extension since I missed the deadline? I'm in a disaster zone.

[DoninGA · Accepted solution]

There are no second extensions.  If you requested an extension on your federal tax return and live in a federally designated disaster area then you have until January 31, 2018 to file your 2016 tax return without penalty.

See this IRS website for information - https://www.irs.gov/newsroom/tax-relief-in-disaster-situations

Any federal income taxes owed were to be paid on April 18, 2017 to avoid a late payment penalty and interest on the unpaid taxes.
