How long do you have to wait to retake the Series 66?
Verified from NASAA, last checked 2026-07-02. Quick answer below, then the full breakdown.
After a first or second failed attempt you must wait a minimum of 30 days before retaking the Series 66. After a third fail, the wait jumps to 180 days, and it stays at 180 days for every attempt after that. Each retake costs another $177.
NASAA sets the Series 66 retake waiting periods:
After a 1st fail: minimum 30 days
After a 2nd fail: minimum 30 days
After a 3rd fail and every attempt after: minimum 180 days
There is no lifetime limit on attempts. Each retake requires a new enrollment (through your firm's Form U4 or self-enrollment) and a new $177 fee, and each enrollment opens a fresh 120-day scheduling window.
Use the wait productively: your failing score report shows section-level results, so you know exactly which of the four sections needs the hours.
