Aggregating RMDS – What Is (And What Is Not) Allowed
Be careful with multiple RMDs! Know the basic aggregation rules below.
IRAs (including SEP and SIMPLE IRAs) - RMDs for each IRA account must be calculated separately, but the total RMD for all IRA accounts may be taken from one (or more) IRA.
Company Plans [excluding 403(b) and IRA-based Plans] - RMDs for each company plan [excluding 403(b) and IRA-based plans like a SEP or SIMPLE] must be calculated separately for each plan and taken separately from each plan.
403(b) Plans - RMDs for each 403(b) account must be calculated separately, but the total RMD for all 403(b) accounts may be taken from one (or more) of the 403(b) accounts.
