The CPA exam is often described as a marathon, not a sprint. But there is a critical detail that adds a ticking clock to this marathon: the 30-month rolling window. Once you pass your first section of the CPA exam, you have 30 months to pass all remaining sections. If you do not complete the exam within that window, your earliest passed section expires and you must retake it. Understanding how this window works is essential for strategic exam planning and avoiding the heartbreak of losing a hard-earned pass.
How the 30-Month Rolling Window Works
The 30-month clock starts on the date you receive a passing score (75 or higher) on your first CPA exam section. From that date, you have exactly 30 months to pass all remaining sections. If 30 months elapse and you have not passed all sections, the earliest section you passed will expire.
Here is a concrete example to illustrate:
- You pass FAR on January 15, 2026. The 30-month clock starts.
- You pass AUD on June 1, 2026.
- You pass REG on February 1, 2027.
- Your deadline to pass your chosen discipline section is July 15, 2028 (30 months from your FAR pass date).
- If you do not pass your discipline section by July 15, 2028, your FAR credit expires.
- If FAR expires, the new window starts from your AUD pass date, giving you until December 1, 2028 to complete the remaining sections.
The key concept is that the window is rolling. It is not a fixed 30-month period from start to finish. Instead, sections continually expire on a first-in, first-out basis. If your earliest section expires, the clock resets to your next earliest pass date.
What Happens When a Section Expires
When a section credit expires, it is as if you never passed it. You will need to sit for that section again, pay the exam fees again, and study all over again. There is no partial credit, no grace period, and no automatic extensions in most jurisdictions.
The emotional toll of losing a passed section is significant. Many candidates describe it as one of the most demoralizing experiences in their CPA journey. Beyond the psychological impact, it adds substantial time and cost to the process. Avoiding section expiration should be a top priority in your exam planning.
Strategic Planning to Avoid Expiration
The best way to protect your credits is to plan your exam schedule strategically from the very beginning. Here are proven approaches:
Plan Backwards from the 30-Month Deadline
Before you sit for your first section, map out a realistic timeline for all four sections. Consider your work schedule, personal commitments, and how much study time you can realistically dedicate each week. If your timeline stretches close to 30 months, you may want to reconsider your pacing.
Take the Hardest Section First
Many candidates and CPA coaches recommend taking the section you expect to find most difficult first, which for most people is FAR. The logic is twofold: you tackle the hardest material when your energy is highest, and if you need a retake, you have the maximum amount of time within the 30-month window to accommodate it.
Build in Buffer Time for Retakes
Do not plan a schedule that only works if you pass every section on the first attempt. Build in at least one or two buffer periods for potential retakes. A realistic schedule might look like this:
- Months 1 to 4: Study for and take Section 1
- Months 4 to 7: Study for and take Section 2
- Months 7 to 10: Study for and take Section 3
- Months 10 to 14: Study for and take Section 4
- Months 14 to 20: Buffer for any retakes
- Months 20 to 30: Additional buffer (ideally unused)
This schedule gives you 14 months to attempt all four sections and 16 months of buffer. That is a comfortable margin that accounts for the reality that many candidates need at least one retake.
How to Pace Yourself
Pacing is about finding the balance between urgency and sustainability. Here are guidelines for different candidate profiles:
Full-Time Workers Studying Part-Time
Most CPA candidates fall into this category. If you can dedicate 15 to 20 hours per week to studying, plan for approximately 8 to 12 weeks of study per section. This pace allows you to complete all four sections in about 10 to 14 months, well within the 30-month window.
Full-Time Students or Career Changers
If you can study 30 or more hours per week, you may be able to prepare for each section in 4 to 6 weeks. Some candidates in this category pass all four sections in 6 to 9 months. The aggressive pace is demanding but minimizes the risk of section expiration.
Candidates with Significant Personal Commitments
If your study time is limited to 10 hours per week or less due to family obligations, health issues, or other commitments, plan for 12 to 16 weeks per section. At this pace, you will need approximately 16 to 24 months for all four sections, which is still within the window but leaves less room for retakes.
Extension Policies
Can you get an extension on the 30-month window? The answer in most cases is no. The 30-month rule is set by the AICPA and adopted by state boards, and most jurisdictions enforce it strictly. However, there are limited exceptions:
- Military service: Active-duty military members deployed during their testing window may be eligible for extensions in some states.
- Medical hardship: A few state boards have granted extensions for documented medical emergencies, though this is rare and not guaranteed.
- Pandemic-related extensions: During the COVID-19 pandemic, many state boards temporarily extended the credit window. Similar extensions could occur during future extraordinary circumstances.
- State-specific policies: Some states have adopted longer credit windows (such as 36 months) or have specific extension provisions. Check with your state board.
Do not rely on extensions as part of your strategy. Plan as if the 30-month window is absolute, and treat any extension as a last resort.
Warning Signs That You Are Running Out of Time
Keep an eye out for these red flags:
- Your earliest passed section is more than 18 months old and you still have two or more sections to pass.
- You have failed the same section twice and your window is shrinking.
- Personal or professional circumstances have significantly reduced your available study time.
- You find yourself postponing exam dates repeatedly.
If any of these apply, it is time to reassess your plan. Consider increasing your study hours, taking time off work if possible, or seeking additional support such as tutoring or a study group.
What to Do If a Section Is About to Expire
If you are in a situation where a section credit is close to expiring, here is a triage approach:
- Prioritize the section that is about to expire. If your FAR credit is expiring in three months and you were planning to take your discipline section, consider retaking FAR first to reset that credit.
- Study aggressively. This may not be sustainable long-term, but short bursts of intensive study can be effective for retakes.
- Schedule the exam as soon as you feel minimally prepared. A slightly underprepared attempt is better than losing the credit entirely, especially since you previously passed the section and have a foundation.
- Contact your state board. In rare cases, there may be options or accommodations you are not aware of.
The 30-Month Window and the 2024 CPA Exam Changes
With the transition to the new CPA exam format in 2024, which replaced BEC with three discipline sections (BAR, ISC, and TCP), the 30-month window rules remain unchanged. You still have 30 months from your first passed section to complete all remaining sections, including your chosen discipline. This is worth noting because the discipline sections are new, and candidates transitioning from the old exam format had their existing credits honored under specific transition rules.
Plan Smart from Day One
The 30-month window is generous enough for well-organized candidates but unforgiving for those who procrastinate or fail to plan. The best strategy is simple: start with a realistic timeline, build in buffers for retakes, maintain consistent study habits, and treat each section with urgency.
