SEE Part 1 retakes and pass validity

A passed SEE Part 1 does not expire in the way a vendor certificate does; it is a carryover credit that stays usable for three years from the date you passed, and the clock matters only until you have passed Parts 2 and 3. If you fail, you may retake Part 1 after 24 hours, up to four times per testing window, paying the full fee each time. All of this comes from the IRS’s enrolled agent FAQ, read on 2026-10-09.

Retakes: what the IRS states

The FAQ does not say whether the four-attempt count resets when a new window opens, and it does not describe an appeal or re-score process. It says only that PSI emails your score report. If you think a question was flawed, the FAQ offers no formal route; the contact page for the Office of Enrollment is the IRS’s channel for questions.

Rescheduling is separate from retaking. Moving an appointment 48 hours or more ahead is free; inside 48 hours, or arriving 30 minutes late or more, costs the full fee again. A no-show forfeits the fee. For accommodation requests the page points to PSI by phone and gives no further detail.

The windows: why October to February matters

Testing is generally offered from May 1 to the end of February, with nothing in March and April while the IRS updates the exam to the latest tax law. The current domestic window runs July 1, 2026 to February 28, 2027. Tax-year content changes with each update: this window uses law as amended through December 31, 2025 and calendar year 2025. A fail in February therefore means a gap of at least two months and a new law base on return, so do not study on the assumption that the questions stay the same. See exam changes for how we track this.

The FAQ also states that scheduling and testing for international candidates is temporarily delayed and that new start dates are undetermined. Check it before planning a sitting outside the US.

The three-year carryover, with dates

The IRS example: a Part 1 pass on Nov. 15, 2025 stays valid for the remaining parts until Nov. 15, 2028. Each part has its own date, so the earliest pass is the one to watch.

A worked timeline for someone passing Part 1 on 2026-12-10:

• 2027-02-28: end of the current window; later sittings wait until after the March-April update.
• 2029-12-10: the Part 1 pass runs out; Parts 2 and 3 must be passed by then.
• Fail the deadline: the FAQ says a candidate who does not use a carried-over score in time loses credit for it, so Part 1 would have to be taken again.

The IRS granted a two-month extension for domestic parts that would have expired between May 1 and June 30, 2026. That exception is dated; do not assume it recurs.

After the exams: what renews and what does not

Part 1 itself has no renewal fee or continuing education. Obligations begin with enrollment. You apply on Form 23 within one year of passing the third part ($140; about 60 days processing per the FAQ). Then, per the IRS’s maintenance page, you renew every three years, with the cycle set by the last digit of your SSN (the Oct. 1, 2026 to Jan. 31, 2027 cycle is for digits 7, 8, 9 or no SSN), on Form 8554. You need 72 hours of continuing education per cycle: 66 qualifying hours plus 6 of ethics, at least 16 a year with 2 in ethics, from IRS-approved providers. The page does not state a renewal fee or lapse and reinstatement terms, so confirm those with the IRS.

Compared with other certifications

Most vendor exams impose a fixed waiting period that grows with each failed attempt. The IRS rule is short (24 hours) but bounded by the window and the fee, and the validity clock runs from your first pass, not your last.
