Additional e-file and perfection period information

Remember to check the e-file status on the return to make sure your return or extension is accepted by the taxing authority. If your return or extension is rejected, follow the guidelines below to make sure it stays timely filed.
Returns and extensions don't have to be Accepted by the IRS or states on March 17 to be considered timely filed. An electronic postmark is assigned to a return when it's received by the Intuit Electronic Filing Center. This electronic postmark is the date and time the return or extension is considered filed. This electronic postmark is reported as the Return Submitted date and time displayed.
The ERO should print the status from the program by copying the information and then pasting it into a text editor. File this document with the paper return or extension.
The ERO is allowed 10 calendar days to resubmit a rejected e-file return.
The ERO is allowed 5 calendar days to resubmit a rejected e-file extension.
See Publication 4163 under the Transmission Perfection Period section for more information.

State-specific information

Most states follow the federal perfection period guidelines but some states do have different rules. Check the state information webpage for the most up to date information.

Alabama Corporation, S-Corporation, and Partnership returns

The state of Alabama allows a 10 business day period to retransmit the corrected return. The perfection period starts from the date the State of Alabama rejects the original submission. The original submission ID must be transmitted with the perfected return. This way the original submission date can be populated in our system to prevent any late filing penalties being assessed.

California Corporation, S-Corporation, and Partnership returns

California Corporation, S Corporation, and Partnership returns that are timely filed electronically and rejected can be corrected and retransmitted within 10 days from the date of rejection to still be considered timely filed.

Georgia Corporation and S-Corporation returns

Georgia follows the IRS guidelines for correcting and resubmitting rejected returns.

Iowa Corporation, S-Corporation and Partnership returns

Iowa no longer offers a perfection period on e-filed returns. For Iowa to consider your returns "timely filed," the state must accept your e-filed returns by the state due date for that type of return.

What to know about Iowa's perfection period policy:

Rejected returns are considered "not filed."
The date/time stamp of the accepted Iowa submission serves as the electronic postmark date, provided that it's within 48 hours of the date/time stamp that the IRS receives it. Otherwise, the date/time that the IRS receives the return serves as the electronic postmark date for Iowa filing purposes.
Automatic clearing house (ACH) direct debit payments submitted with returns are processed only if returns are accepted.

It's recommended that you transmit your ACH direct debit payments stand-alone rather than with the return if you can't submit an acceptable return to Iowa by the payment due date.

Kansas follows the IRS guidelines for correcting and resubmitting rejected returns.
