Can I choose a different EDD SDI base period to increase my WBA? Higher earnings excluded from calculation
I'm planning to file for disability next month due to an upcoming surgery and I've been looking into how my weekly benefit amount will be calculated. Here's my situation: I had a minor injury about 18 months ago that caused me to work reduced hours for several months, but I've been back to full-time (with higher pay) for the past 6 months. I noticed when reviewing the EDD website that they use a base period that excludes the most recent months where I've been earning more. From what I understand, they'll use earnings from about 5-17 months before my claim start date. The EDD website mentions something about "alternate base periods" but doesn't really explain if I can choose this BEFORE filing my claim. I'm worried my WBA will be significantly lower if they use the period when I was working reduced hours. Has anyone successfully requested a different base period calculation? Is this even possible or am I stuck with whatever default period they use? I've tried calling EDD multiple times but keep getting disconnected. Any advice would be appreciated!

From my understanding, the alternate base period (ABP) is only available automatically if you don't qualify for benefits using the standard base period. You can't just choose it because it would give you a higher weekly benefit amount. The ABP uses more recent quarters, but EDD only considers it if you don't have enough wages in the standard period to establish a claim.

•That's disappointing. So even though I have HIGHER wages in the more recent quarters, I'm stuck with the standard calculation that uses my lower-earning period?

Actually, the previous comment isn't entirely accurate. The Alternate Base Period (ABP) is primarily designed for people who don't qualify under the Standard Base Period, but there are some specific circumstances where you can request a different calculation. Have you checked if you qualify for what's called a "Special Base Period"? This is different from the ABP and applies to people who were unable to work during their base period due to a previous illness or injury (which sounds like it might apply to you based on your reduced hours from the previous injury). I'd recommend filling out the DE 2588 form (Special Base Period Request) when you file your claim. You'll need medical documentation of your previous injury that caused the reduced earnings period. Hope this helps!

•Thank you so much for this information! I hadn't seen anything about a "Special Base Period" or the DE 2588 form. I definitely have medical documentation of my previous injury. I'll look into this right away.

ive been on sdi 3 times and they ALWAYS use the oldest earnings period not the newest. its so STUPID bc most people make more as time goes on. the system is designed to pay u less its not a mistake!!!! they do it on purpose to save $$$$

•While it seems unfair, there's actually a logical reason for how the base period works. The system is designed to use earnings from 5-17 months before your claim start date because they need verified wage data from completed quarters. The most recent 1-4 months aren't included because those wages might not be fully reported or processed by employers yet. It's not specifically designed to pay less, though I understand the frustration.

I went through something similar last year! Had a baby and my maternity leave claim used quarters when I was working part-time during school instead of my full-time job after graduation. My benefit was like half what I expected. Called and they said nothing they could do, some rule about how the quarters have to be calculated. So frustrating!

•That's exactly what I'm worried about happening to me. Did you try submitting any special requests or forms to change it? Or were you just stuck with the lower amount?

•I was just stuck with it unfortunately. I didn't know about the special base period form the other commenter mentioned though. Wish I had known about that!

If you're having trouble getting through to EDD to ask about this, I'd recommend trying Claimyr (claimyr.com). I was in a similar situation trying to get specific answers about my base period and was going crazy trying to reach someone. Their service connected me to an EDD rep in about 20 minutes when I'd been trying for days on my own. They have a video showing how it works here: https://youtu.be/1X-mEsLtbmQ?si=1hcSq3KFtCr4oAmd. Definitely worth it for complicated questions like yours where you need actual advice from EDD rather than just guessing.

•Is this legit? Seems sketchy to pay someone else just to call EDD for you...

•It's definitely legitimate. They don't call FOR you - they just get you into the EDD phone queue faster. You still talk directly with the EDD representative yourself. I was skeptical too but it saved me hours of frustration.

To give you a more complete answer on this topic: 1. Standard Base Period: Uses earnings from 5-17 months before your claim begins 2. Alternate Base Period (ABP): Uses earnings from 1-13 months before your claim. This is ONLY available if you don't qualify for a claim under the standard base period. 3. Special Base Period: Available if you were unable to work in your base period quarters due to a workers' comp injury, illness, or other covered reason. Requires form DE 2588 and medical documentation. Based on what you've described, the Special Base Period request is your best option. You'll need to: - Complete form DE 2588 when filing your claim - Provide medical documentation of your previous injury - Explain how it affected your work hours/earnings during the standard base period The EDD representative will review your request and determine if you qualify. I recommend filing your claim online, then immediately following up with a phone call (using the service someone mentioned or persistent calling) to make sure they're aware of your special base period request.

•Thank you for breaking this down so clearly! I've found the DE 2588 form online and I'm gathering my medical documentation now. This gives me hope that I might be able to have my most recent earnings included. I'll definitely make that follow-up call once I submit everything.

Quick question - does anyone know if requesting the special base period delays the processing of your claim? I'm worried about starting this whole process and then having to wait even longer for benefits to start because of the special request.

•In my experience helping clients with SDI claims, requesting a Special Base Period can add about 1-2 weeks to the processing time, since it requires manual review. However, benefits are still paid from the date of disability once approved - they're not delayed because of the review time. If you're concerned about the waiting period, I'd recommend submitting your claim a few weeks before your surgery if possible.

Update: I was finally able to speak with someone at EDD! The representative confirmed that I can submit the DE 2588 form for a Special Base Period consideration based on my previous injury. She said it's not guaranteed but definitely worth applying for in my situation. For anyone else in a similar situation - make sure you have medical documentation that specifically shows you were unable to perform your "regular or customary work" during the base period quarters due to disability. This doesn't have to be a complete inability to work - reduced hours due to medical limitations can qualify. I'll update again once I find out if my request is approved. Thanks everyone for your help!

That's fantastic news that you got through to EDD and they confirmed you can submit the DE 2588! Your situation is exactly why the Special Base Period exists - to prevent people from being penalized when previous medical issues affected their earnings during the standard calculation period. One tip from my own experience: when you submit your medical documentation, make sure it clearly states the specific time period you were affected and how it limited your work capacity. The more detailed and specific the documentation, the stronger your case will be. Really hoping this works out for you and you get a fair WBA calculation. Your persistence in researching this and following through could help a lot of other people in similar situations who might not know about this option. Best of luck with your surgery and recovery!

•This is such valuable information for anyone dealing with similar situations! I'm new to this community and currently researching SDI options myself. Miguel, thank you for sharing your journey through this process - it's really helpful to see the real steps someone took to address the base period issue. The DE 2588 form wasn't something I had come across in my research either. Hope your surgery goes well and that the Special Base Period request gets approved!

As someone who just went through the SDI application process myself, I want to emphasize how important it is to be thorough with your documentation when submitting the DE 2588 form. I had a similar situation where a previous work injury affected my earnings during the base period. What really helped my case was getting a letter from my doctor that specifically outlined the dates I was on work restrictions and how those restrictions impacted my ability to perform my regular job duties. The letter included details about reduced hours, modified duties, and the medical reasons for these limitations. Also, if you have any correspondence with your employer from that time period (emails about schedule changes, HR documentation of accommodations, etc.), include those as supporting evidence. The more you can document the connection between your medical condition and reduced earnings, the stronger your Special Base Period request will be. The whole process took about 3 weeks for me, but it was absolutely worth it - my WBA ended up being almost 40% higher than what it would have been under the standard calculation. Don't give up on this, Miguel - it sounds like you have a solid case for the special base period!

•This is incredibly helpful, Emma! I'm just getting started with understanding the SDI process and had no idea how detailed the documentation needed to be. Your point about including employer correspondence is something I wouldn't have thought of. It's really encouraging to hear that the Special Base Period request can make such a significant difference in the WBA calculation - a 40% increase is huge! For someone like Miguel who clearly has the medical documentation and reduced work history, it sounds like this could really pay off. Thanks for sharing the specific details about what made your case successful!

•Emma, this is exactly the kind of detailed guidance that makes such a difference! I'm new to navigating the SDI system and your breakdown of what documentation worked for you is invaluable. The 40% WBA increase really shows how much impact the Special Base Period can have. Miguel, it sounds like you're on the right track with getting that medical documentation together. One question for Emma - did you submit the DE 2588 form at the same time as your initial claim, or did you file it separately afterward? I'm trying to understand the best timing for this process.

•Great question about timing! I submitted the DE 2588 form at the same time as my initial SDI application online. There's actually a section during the online filing process where you can indicate if you want to request a special base period calculation. I'd recommend doing it this way rather than filing separately afterward, as it keeps everything together and potentially speeds up the review process. When I filed online, I uploaded all my supporting documentation (doctor's letter, employer emails, etc.) right then and there. The EDD representative I spoke with later confirmed this was the best approach since it flags your case for manual review from the start rather than having to go back and modify an already-processed claim.

•This thread has been incredibly educational! I'm just starting to research SDI benefits myself and had no idea about the Special Base Period option. Emma, your 40% WBA increase really demonstrates how significant this can be. The detail about getting employer correspondence is particularly valuable - I wouldn't have thought to save emails about schedule modifications. Miguel, it sounds like you have a strong case with your injury documentation and the reduced hours period. Has anyone here dealt with how long it typically takes to get a decision on the DE 2588 request once it's submitted? I'm curious about the timeline since Miguel mentioned his surgery is coming up next month.

•Based on my recent experience with the DE 2588 process, the decision timeline is typically 2-3 weeks from when you submit your complete application with all supporting documentation. However, I'd strongly recommend that Miguel file his claim as soon as possible rather than waiting until right before his surgery. Even if the Special Base Period request adds some processing time, SDI benefits are retroactive to your date of disability - so filing earlier won't hurt and gives you a buffer for any potential delays. Emma's advice about uploading everything at once during the initial filing is spot on. The key is having all your medical documentation ready to go when you file. Miguel seems well-prepared with his injury records, so hopefully his timeline will be smooth!

As someone new to this community who's been researching SDI options, this entire thread has been incredibly enlightening! Miguel, your proactive approach to researching the base period calculation before filing is really smart - most people probably just accept whatever WBA they're given without realizing there might be options. The information about the DE 2588 form and Special Base Period is something I hadn't come across in any of the official EDD materials I've been reading. Emma's success story with the 40% WBA increase really shows how impactful this can be for people who had legitimate medical reasons for reduced earnings during their base period. One thing that strikes me from reading everyone's experiences is how much the system seems to rely on people knowing to ask the right questions and submit the right forms. It's unfortunate that this isn't more clearly explained upfront, but threads like this are so valuable for helping people navigate the process. Miguel, I hope your Special Base Period request gets approved and your surgery goes smoothly. Thank you for sharing your journey - it's going to help a lot of people who find themselves in similar situations!
