I just went through this exact same process last month! The confusion is totally understandable because the rules aren't super clear until you dig into the specifics. Here's what I learned: since you're going from sole prop to LLC, you need to figure out how your LLC will be taxed. If you're staying as a single-member LLC and NOT electing corporate taxation, you can actually keep using your existing sole prop EIN. The IRS treats single-member LLCs as "disregarded entities" by default, which means for tax purposes, you're still essentially a sole proprietorship. However, if you're adding partners (making it multi-member) or electing S-Corp or C-Corp taxation, then yes, you need a new EIN. The good news is there's no formal process to "cancel" your old EIN if you do need a new one - you just stop using it and start using the new one. I'd recommend calling the IRS Business Tax Line to confirm your specific situation, though fair warning - it can take a while to get through! Also, make sure to update your EIN with your bank, any business accounts, and vendors once you figure out what you need to do. That was the part I almost forgot!

This is such a common source of confusion! I went through the same thing when I converted my consulting business from sole prop to LLC last year. The deciding factor really comes down to your tax election. Since you mentioned you're doing this for liability protection (smart move!), you're probably planning to stay as a single-member LLC with disregarded entity status - which means you can absolutely keep your existing EIN. One thing I wish someone had told me earlier: even though you can keep the same EIN, make sure to update your business name with your bank and any vendors to reflect the LLC. I kept getting confused looks when my checks said "ABC Consulting LLC" but my EIN paperwork still showed my personal name from the sole prop days. Also, definitely keep good records of when you made the transition. I created a simple folder with my LLC formation date, operating agreement, and a note about continuing to use my sole prop EIN. Makes things much cleaner if the IRS ever has questions down the road. The liability protection alone makes the LLC worth it - you're making a smart business decision even if the tax side stays exactly the same!

I can definitely relate to your situation! I went through something very similar earlier this year - received a 4464C letter and immediately thought I had done something wrong with my taxes. The stress was overwhelming, especially when I needed my refund for some urgent expenses. From my experience and what I learned talking to an IRS agent, the 4464C letter is actually quite routine when you have significant income changes like you described. Your job change and income increase (tripling your salary) would definitely trigger their automated review system. The fact that your transcripts don't show any employer income yet is almost certainly just a processing delay, not an indication that your employers failed to report anything. What helped me the most was understanding that this is a verification process, not an audit or indication of wrongdoing. The IRS is simply making sure that what you reported matches what they receive from your employers. Once their systems catch up and process all the W-2 data, most of these cases resolve automatically. I know the waiting is incredibly stressful when you're counting on that refund money for necessary expenses like your car repairs. Try to be patient - the 60-90 day timeframe others mentioned is realistic, though many cases resolve faster. Keep checking your transcripts weekly if you can access them online, and once your employer income data appears there, your refund should process pretty quickly after that. You're definitely not alone in this situation - it seems like a lot of people are dealing with these income verification letters this year due to processing delays and economic changes that led to more job switches. Hang in there!

I'm going through this exact same situation right now! Just received my 4464C letter last week and was initially terrified that I had made some huge mistake on my return. Like you, I switched jobs mid-year with a significant income increase (went from $35K to about $85K), so reading all these experiences has been incredibly reassuring. What really struck me is how common this seems to be this year - it sounds like the combination of processing delays and people changing jobs during the economic shifts has created a perfect storm for these income verification reviews. I was beating myself up thinking I must have done something wrong, but now I understand it's just their system flagging normal life changes for verification. I've been obsessively checking "Where's My Refund" multiple times a day since I got the letter, which has been driving me crazy. I'm definitely going to adopt the weekly checking routine that several people mentioned here - seems much healthier for my sanity while waiting for this to resolve. The most helpful thing I've learned from this thread is that the missing employer data on transcripts doesn't mean anything went wrong with W-2 filings - it's just processing delays on the IRS side. That was my biggest worry since I kept seeing zeros everywhere when I checked. Thanks to everyone who shared their timelines and experiences. Knowing that most people eventually get their refunds processed, even if it takes 60-90 days, gives me hope that this will work out. The waiting is brutal when you're counting on that money, but at least now I know I'm not alone in dealing with this!

As a newcomer to this community, I'm absolutely blown away by how thorough and helpful this entire discussion has been! I just started my first job out of college and found myself in the exact same predicament - my HR department casually mentioned I needed to complete some "W4T" and "W4V" forms, and I immediately went into panic mode trying to figure out what these were. Reading through everyone's experiences has been such a tremendous relief. It's incredible to learn that this type of confusion is so widespread and typically stems from companies using their own internal terminology rather than official IRS form names. Before finding this thread, I was convinced I was somehow lacking fundamental tax knowledge that everyone else possessed! What I found most valuable was the consistent guidance to ask HR to physically show you the forms rather than just going by verbal descriptions. I was honestly too intimidated to admit I didn't recognize what they were referring to, but now I understand that seeking clarification is actually the responsible and professional approach. The comprehensive breakdown of official IRS withholding forms (W-4 for standard employment, W-4P for pensions/annuities, W-4V for voluntary government payment withholding, W-4S for sick pay) is going straight into my professional reference folder. Having this foundational knowledge should help me confidently identify when something doesn't align with standard IRS terminology. Thank you to everyone who shared their expertise, personal stories, and practical wisdom - from tax professionals providing authoritative guidance to community members documenting their journey from confusion to clarity. This is exactly the kind of supportive, educational environment that makes navigating complex workplace tax situations so much more manageable for those of us just beginning our professional careers!

As a newcomer to this community who just went through a very similar experience, I wanted to add my voice to this incredibly helpful discussion! Like so many others here, I was completely puzzled when my new employer mentioned forms I couldn't find anywhere online. What really resonates with me is how this thread demonstrates that our initial instinct to panic or feel inadequate is completely misplaced. The real issue isn't our lack of knowledge - it's the widespread practice of companies using non-standard terminology that creates unnecessary confusion for employees. I particularly appreciate how this discussion has evolved into such a comprehensive resource. The practical steps that emerged (asking to see actual forms, cross-referencing with IRS documentation, seeking clarification from HR) provide a clear framework for handling these situations confidently. The reference list of official IRS withholding forms has been invaluable - it's amazing how having that baseline knowledge transforms your ability to identify when something might be company-specific shorthand versus an actual IRS requirement you should know about. For anyone else dealing with similar confusion: don't let unfamiliar form names intimidate you. As this thread clearly shows, asking the right questions is not only acceptable but actually demonstrates that you're taking your tax responsibilities seriously. Thank you to everyone who contributed to making this such an educational and reassuring discussion for newcomers like myself!

I'm at 14 weeks waiting on my injured spouse claim too. From what I've researched, the IRS is really backed up this year - some people are reporting 20+ weeks. Have you checked your transcript lately? Sometimes there are updates there before they send any official notices. The waiting is brutal but unfortunately seems pretty normal for 2025 😕

I'm at 19 weeks on my injured spouse claim and still nothing! This is absolutely ridiculous. Filed in early September and here we are in January with zero movement on my transcript. I've called 4 times and each rep just says "keep waiting" - like thanks for nothing. At this point I'm wondering if they even received my paperwork. The financial stress is real when you're counting on that refund. Anyone else hitting the 20+ week mark?

Has anyone tried the Business Tax Express line (the special one where you have to be invited)? I heard they can check all your business filings in one call. My CPA mentioned it but said it's only for tax professionals.

I went through a similar nightmare last year with multiple LLCs that I'd converted to S-Corps. The absolute fastest way I found was to create an IRS online account for each business entity at irs.gov/payments. Once you're logged in, go to "Business Tax Account" and then "View Account Information." This will show you a summary of what returns the IRS has on file for each entity, including filing dates and any outstanding balances or notices. It's much faster than waiting for transcripts and gives you immediate visibility into what's actually been processed versus what you think you filed. The key thing is you'll need the EIN and business information for each entity to set up separate accounts. For S-Corp elections, you can also check if they were properly processed by looking at the entity classification on your account - it should show "S Corporation" rather than "Partnership" if the election was accepted. This won't give you the detailed line-by-line information that transcripts provide, but it's perfect for quickly identifying which entities have missing returns so you know where to focus your efforts.
