New CPA Issue: IRS advised to paper file because child's SSN is too new/fresh
Hey tax friends, I've been preparing returns for a couple years, but this is my first time running into this issue. Need some guidance from more experienced folks. I've got this family I'm working with who just had a new baby in late December. They received the SSN in early January, and when I tried to e-file their return, it got rejected with SEIC-F1040-535-04 error ("For each child on Schedule EIC (Form 1040), 'QualifyingChildSSN' and 'ChildBirthYr' must match that in the e-File database"). I triple-checked everything - SSN card, birth certificate, dates - all the info is 100% correct. Called IRS and they basically said "yeah, the SSN is too new to be in our e-file database yet, you'll need to paper file." My big question is - how long will paper filing take with this situation? Does it make more sense to file an extension and try e-filing again in a month or two when the SSN might be in their system? The family is expecting a decent refund with the new child tax credit and EIC, so they're anxious to get their money but don't want major delays.

This is a relatively common issue with newer SSNs for dependents. The IRS database that validates SSNs for e-filing doesn't update as quickly as the main SSN database. For a child born in December with a January-issued SSN, the lag time can be up to 8-10 weeks before it's recognized in the e-file system. If you paper file now, you're looking at approximately 6-8 weeks for processing (maybe longer with the current backlog). If you file an extension and wait to e-file, it might actually be faster in the long run. My recommendation would be to contact the IRS again and specifically ask if the SSN is now in their system (sometimes they can check). If not, I'd explain the situation to your clients and give them the option: paper file now or wait 3-4 weeks and try to e-file again. If they're financially dependent on that refund, paper filing might be the safer bet since we know e-filing might not work for a while.

•How do you even get through to the IRS to ask these questions? I've been on hold for hours trying to talk to someone about a similar issue.

•The best times to call are early morning (right when they open) or later in the week (Thursday/Friday). The general number is often swamped, but if you use the practitioner priority service line (assuming you have a PTIN), you can usually get through with shorter wait times. The practitioner priority service has been much more responsive in my experience, typically 15-30 minute waits versus hours on the general line. If you don't have access to that line, try calling right at 7am Eastern when they first open.

I had this exact problem last year with a client who had twins in November! I spent hours on the phone with the IRS and ended up super frustrated. Then I found taxr.ai (https://taxr.ai) which saved me big time. I uploaded the rejection notice and the baby's SSN card (with sensitive info blacked out) and their system analyzed it all and gave me really specific guidance. Turns out there's actually a way to get a manual review for these situations, and they walked me through exactly what form to submit and how to word the explanation. The client got their refund within 3 weeks! Might be worth checking out since it's specifically designed for unusual document/transcript issues like this one. It's been a huge help for my small practice when dealing with these weird edge cases.

•That sounds interesting but kinda skeptical. How does it actually help with the IRS systems? The problem is that the IRS database doesn't have the SSN yet, right? So how does an external service solve that?

•Can this service handle business tax issues too? I'm dealing with an EIN validation problem for a new LLC and it's been a nightmare getting it resolved.

•It doesn't actually change anything in the IRS database - what it does is analyze the rejection code and your specific situation, then recommends the fastest solution path. In my case, it identified that I qualified for a special paper filing procedure with a specific cover letter format that gets routed differently than regular paper returns. As for business tax issues - yes, they handle those too! I've used it for S-Corp and Partnership issues as well. It works with any tax document that's giving you trouble, including EIN validation problems. You upload the notices or rejection codes and it analyzes what's happening. Saved me so much time compared to waiting on hold with the IRS.

Just wanted to follow up about taxr.ai - I tried it for my LLC issue I mentioned and wow, it actually delivered. The system immediately identified that my EIN validation error was happening because the business name on my articles of organization had a hyphen but the IRS registration didn't. I was about to paper file everything but taxr.ai showed me how to submit an expedited name matching request directly to the e-file department (something I had no idea existed!). Got confirmation within 48 hours and was able to e-file successfully. Definitely worth checking out for these weird system issues with the IRS.

For anyone facing IRS help issues - if you really need to talk to a live person at the IRS about this SSN problem or anything else, try Claimyr (https://claimyr.com). I was super skeptical at first but they actually got me through to an IRS agent in about 20 minutes instead of waiting for hours. Check out their demo video if you're curious how it works: https://youtu.be/_kiP6q8DX5c I was trying for days to get through about a similar database mismatch issue (client's name change wasn't in the system). Claimyr connected me to an actual IRS rep who was able to tell me exactly when the update would hit their e-file system. Saved me from submitting a paper return that would have taken months to process.

•How exactly does this work? The IRS phone system is absolutely terrible - are they somehow bypassing the queue?

•Yeah right. Nothing gets you through to the IRS faster. I've tried everything and always end up waiting 2+ hours or getting disconnected. Sounds like a scam to me.

•It uses an automated system that navigates the IRS phone tree and waits on hold for you. When it reaches an actual agent, you get a call connecting you directly. It's completely legitimate - they're just saving you from having to wait on hold yourself. No, they're not bypassing anything or doing anything shady. They're just using technology to handle the hold time so you don't have to sit there with a phone to your ear for hours. It's basically like having an assistant wait on hold for you and then transfer the call when someone answers.

I have to admit I was totally wrong about Claimyr. After posting my skeptical comment, I was desperate to resolve a similar SSN issue for a client and decided to try it as a last resort. Got connected to an IRS agent in about 37 minutes (which is LIGHT YEARS faster than my previous attempts). The agent confirmed that newly issued SSNs take 4-8 weeks to appear in the e-file validation database, but they gave me a direct fax number for a special processing unit that handles these cases. Just submitted the return with supporting documentation yesterday, so hoping for the best. Just wanted to come back and say it actually works. Not being paid to say this - just surprised it delivered after being so skeptical.

Another option worth considering - have you tried using the Non-Filers tool for just getting the dependent into the system? I had a similar issue last year and found that if the child is registered through that portal, it sometimes updates the database faster than waiting for the normal sync.

•I didn't even think about using the Non-Filers tool! That's a creative approach. Do you know if there are any drawbacks to doing it that way? I'm a bit concerned about creating confusion in their systems by using a tool that's not specifically designed for this purpose.

•There's one important caveat - you'd only want to register the child through the tool, not submit any tax information for the parents. The Non-Filers tool is primarily designed for people who don't need to file a full return. I wouldn't recommend this as a first approach, but if you've already waited 4+ weeks since the SSN was issued and the client really needs that refund ASAP, it can sometimes help. In my case, the SSN appeared in the e-file database about a week after using the tool, but that could have been coincidental timing.

I'm having the same issue with a client's adopted child - SSN was issued in February and we're still getting the rejection. Did you end up paper filing or waiting? I'm trying to decide what to tell my clients about timeframes.

•Not OP but I had this with an adoption case last year. Paper filing took almost 4 months to process, but they did eventually get their full refund with interest. If your clients can wait, it might be worth trying e-file again in a few weeks.

•I ended up explaining both options to my clients and they decided to paper file since they wanted to get the process started. I made sure to use certified mail with return receipt and included a cover letter explaining the situation. I'll post an update when they receive their refund. They understand it might take 8-12 weeks based on current processing times.

Just dealt with this exact scenario last month! Had a client with twins born in late November, SSNs issued in December. Same rejection code you got. What worked for us: I called the practitioner priority line (as Mason mentioned) and the rep actually walked me through a workaround. There's a specific form you can attach to a paper return called Form 8948 that expedites processing for SSN database mismatches. The key is writing "NEW DEPENDENT SSN - DATABASE MISMATCH" in red ink across the top of the first page. We paper filed with this approach and got the refund processed in just under 5 weeks, which was way faster than the 8-12 weeks they initially quoted. The rep also mentioned that February-March is actually prime time for these issues since so many December babies get their SSNs in January. One tip: make copies of everything and send via certified mail. The IRS has been losing a surprising number of paper returns lately, and you'll want that tracking confirmation.
