Definition
An IRS exception that lets you take penalty-free withdrawals from an IRA or a former employer's 401(k) before 59½ by committing to a fixed series of annual payments calculated from your account balance and life expectancy using one of three IRS-approved methods. Income tax still applies. The schedule must continue for five years or until you reach 59½, whichever is longer.
Why it matters
SEPP is the early-retirement tool of last resort because it is rigid: change or stop the payments early and the IRS charges the 10% penalty retroactively on every withdrawal taken, plus interest. Splitting an IRA first so that only part of it is locked into the schedule is the usual way to keep some flexibility.
