The original retirement-account workhorse. Traditional IRAs follow the standard owner-RMD path: Uniform Lifetime divisor, Dec 31 deadline, and aggregable with your other Traditional, SEP, and SIMPLE IRAs into a single computed total you can withdraw from any one account.

TableUniform Lifetime Table (Pub 590-B Appendix B). Joint Life only if your sole beneficiary is a spouse more than 10 years younger than you.
DeadlineDec 31 each year. Your first RMD may be deferred to April 1 of the year after you reach RBD age — but doing so means two RMDs in that year.
