What This Code Means

Code 977 reflects that the IRS has received and posted an amended return for the tax year. It indicates that account processing includes changes submitted after the original filing. This code records the amended return entry into IRS systems but does not confirm acceptance of all changes. It does not specify whether additional tax is due or a refund is generated. It signals that amendment processing has begun at the account level.
