Who Must File

Amended return. Partnerships and real estate mortgage investment conduits (REMICs) that become aware of incorrect items of income, deductions, etc., use Form 1065-X to correct their previously filed paper partnership or REMIC return. See Specific Instructions, later, for information on completing Form 1065-X as an amended return.

Note: To make adjustments to partnership-related items, partnerships under BBA must file an AAR instead of an amended return unless there is specific guidance allowing for the filing of an amended return. For information on BBA partnerships filing Form 1065-X, go to IRS.gov/BBAAAR .

AAR under BBA. File Form 1065-X if you’re the partnership representative (PR) or the designated individual (DI) (if the PR is an entity) requesting an administrative adjustment to correct a previously filed partnership return on behalf of the BBA partnership. See Partnership representative (PR), later, for the definition of a PR. Go to IRS.gov/BBAAAR for additional information.

AAR-REMICs. For tax years beginning after 2017, REMICs that had more than one residual interest holder at any time during the tax year and didn’t elect out of the centralized partnership audit regime use Form 1065-X to file an AAR. See Specific Instructions, later, for information on completing Form 1065-X as an AAR.

Tip: When a partnership’s or REMIC’s federal return is changed for any reason, it may affect its state return. For more information, contact the state tax agency with which the state return is filed.
