Can I file to extend my return after getting the automatic extension until 10/17/22?

[mldublin]

My extended return is due tomorrow 10/17/22 and I still have missing records and need more time.  Can I extend again?

Nope ... now you will simply file late.   If you are getting a refund the deadline tomorrow is immaterial.

END OF YEAR STEPS FOR ONLINE USERS
E-file servers are shut down for the year for personal returns. No exceptions!   You won't be able to work on your return or get a copy of it after Oct 22.

If you have already filed your return I would double check that both federal and state were accepted here,
https://shop.turbotax.intuit.com/efile/efile_status_lookup.jsp 

If you haven't filed or finished yet you only have until Oct 17 to finish and efile.   If you efile by Oct 17  you should still save and print out the pdf file NOW so you can mail it in case your efile gets rejected and you are not able to get it to go through.  

If you don't efile by Oct 17 you will have to print and mail it.  If you don't finish your return you will have to switch to the Desktop program.  So you might want to switch NOW.  To switch from online to desktop and continue in the desktop version see this…….

You can buy a cd or download the program here https://turbotax.intuit.com/personal-taxes/cd-download 
or look around at stores for sales.   Or if you already paid for the Online version you can call in and ask if they will switch you over.  Contact Customer Service  https://ttlc.intuit.com/questions/1899263-what-is-the-turbotax-phone-number?jump_to=answer_3300041 

BEFORE OCT 17
Either way if you have already filed or not filed you should save both the .tax file and the pdf file to your computer so you will always have access to it.  You might need to amend it or need a copy to get a loan, etc.

AFTER OCT 17
October 22, 2022 is the Final deadline to resubmit a rejected return that was originally e-filed on or before October 17.  If you're expecting a refund and miss the October 22 final cutoff date, you have until April 15, 2025 (October 15, 2025 if you filed an extension) to file a paper return and claim your 2021 refund.

There are no second extensions.  

If your tax return has a tax refund there are no penalties for filing after the due date of the tax return.

However, if you have taxes owed you can file your tax return now and pay the taxes owed.  Then when your records arrive you can file an amended 2021 tax return.
