"When the Internal Revenue Service Acknowledges your submitted Application, they may reject it because it contains errors. If these errors can be corrected, you may VISIT OUR SITE and re-submit your information. As long as you re-submit your application within FIVE CALENDAR DAYS of the rejection, your Electronic Postmark Timestamp will be the same, and, if accepted, your Application will be on time, even if it was re-submitted after the deadline. Some errors can’t be corrected - usually if there’s a problem with your Taxpayer Identification Number, or if an application or return has already been accepted for your Taxpayer Identification Number. In these cases, we recommend that you contact your local Internal Revenue Service Office - https://www.irs.gov/help/contact-your-local-irs-office If the Internal Revenue Service reports any error, we will email you with an explanation of the errors and whether you can correct them."
