How do I correct a return if I misunderstood the rules for an inherited IRA or retirement account?

For the relevant filing, inherited retirement account rules depend on the type of account, the beneficiary's relationship and status, the original owner's age and required distribution status, and the year of death. From a tax compliance standpoint, beneficiaries should avoid moving the money through a personal checking account or attempting an ordinary rollover before confirming the correct inherited account procedure and distribution schedule. For tax reporting purposes, the broader picture is to separate what happened before death, after death, and after distribution because those dates can move income between different returns. Keep the underlying source records together, and let a CPA, enrolled agent, or tax attorney check the reporting party, form, basis, and filing date before the return is submitted.
