How long must an ERO retain his copy of Form 8453?

The correct retention period for an Electronic Return Originator's (ERO's) copy of Form 8453 is until the end of the calendar year in which the associated return was filed. This requirement aligns with maintaining adequate records for tax purposes, ensuring that EROs have access to documentation that supports the electronic filing of returns for a sufficient period.

Form 8453 serves as a declaration of the taxpayer's intent to file the return electronically and provides important information concerning the return, such as consent for electronic filing. By retaining this form until the end of the year it was filed, EROs are equipped to address any inquiries or issues that may arise during that tax year associated with the filed return.

Other options suggest longer or different durations for retention, which do not align with the established regulations governing record retention for electronic filings. Understanding the correct duration for retention of Form 8453 is essential for EROs to remain compliant with IRS guidelines.
