This is such a helpful thread! I'm in a similar situation and was totally confused about the EIN requirements. Just to make sure I understand correctly: I can open a Solo 401k right now as a sole proprietor using my SSN, and then I'll need to get a separate EIN specifically for the retirement plan itself (not for my business). Is that right? Also, when you all mention "Form SS-4 for banking purposes" - is that different from the SS-4 you'd file when starting a new business? I want to make sure I'm checking the right boxes when I apply for the plan EIN. One more question - if I decide to form an LLC later for liability protection, would I need to transfer the Solo 401k to the LLC or can I keep it under my original sole proprietorship structure? Some of the comments mention it depends on how the LLC is taxed but I'm still a bit unclear on the details.

This thread has been incredibly helpful! I'm actually a tax preparer and see this confusion all the time with my self-employed clients. Just wanted to confirm what everyone's been saying and add a few practical tips: You absolutely CAN open a Solo 401k as a sole proprietor with just your SSN - I help clients do this regularly. The plan EIN is totally separate and you'll apply for it after opening the account. A few things to keep in mind: - Make sure you have legitimate self-employment income (1099s, business income, etc.) - The contribution deadline is your tax filing deadline (including extensions) - You can actually contribute for 2024 up until April 15, 2025 if you haven't already - Keep good records of your contributions for tax preparation One last tip: if you're making good money as a freelancer, definitely run the numbers on a Solo 401k vs SEP-IRA. The Solo 401k almost always wins for contribution limits, but the SEP-IRA can be simpler if you ever plan to hire employees. Most of my self-employed clients without employees go with the Solo 401k for the higher limits. Good luck with your retirement planning!

I just wanted to chime in as someone who's been through this exact scenario multiple times. Code "B" is absolutely the right choice for your situation - when your 1099-B shows that cost basis wasn't reported to the IRS, that's exactly what Code "B" is designed for. One thing that might help ease your mind: this is actually a very common situation, especially with certain brokers who don't report cost basis for all types of transactions. The IRS is completely used to seeing Code "B" on Form 8949, and as long as you have your purchase records to support the cost basis you're reporting, you're in good shape. I'd also recommend double-checking your math before submitting - make sure the gain/loss you calculate by subtracting your cost basis (column e) from the proceeds (column d) makes sense based on what you remember about those trades. It's an easy way to catch any data entry errors before filing. You're doing everything correctly by selecting Box B at the top and using Code "B" for each transaction. Don't let the complexity of the instructions psych you out - your situation is straightforward and you've got all the information you need to file accurately.

I've been dealing with this same issue and wanted to share what I learned from my tax preparer. When your 1099-B shows "basis not reported to IRS," you're absolutely on the right track with Code "B" in column (f). One thing that helped me understand this better: the reason your broker didn't report the cost basis to the IRS is often because they don't have complete records of when you originally purchased the stock (maybe you transferred it from another broker, or it was gifted/inherited, etc.). But since YOU have the purchase information, you're required to report it yourself on Form 8949. The key is making sure you have documentation to back up the cost basis you're reporting. Keep your purchase confirmations, transfer statements, or whatever records show how you arrived at that cost basis number. Also, just a heads up - if any of these transactions resulted in losses and you have similar stocks, double-check that you're not dealing with wash sale rules. That would require a different code and adjustments in column (g). But for straightforward unreported basis situations like yours, Code "B" is definitely the way to go.

One thing to consider - the excise tax is only $2.10 (6% of $35), which is less than the $25 processing fee for withdrawing the excess. Financially, you made the right call. If I were you, I would: 1. Answer "No" to FreeTaxUSA's question about withdrawing the excess 2. Make sure Form 5329 is included with your return (the software should handle this) 3. Pay the small excise tax now 4. Keep documentation from your HSA custodian showing the recharacterization 5. When filing next year, be aware that your 2025 contribution limit effectively includes this $35 The most important thing is proper documentation. As long as you have proof of what happened and report it accurately, you'll be fine!

Great advice from everyone here! I just want to add one more thing that might help - when you're dealing with HSA overcontributions in the future, timing really matters. If you catch the error before your tax filing deadline (including extensions), you can withdraw the excess contribution AND any earnings on it without penalty. But once you file your return, you're locked into either paying the 6% excise tax or dealing with more complex correction procedures. For your current situation, you've already made the right choice given the circumstances. The $2.10 excise tax is definitely better than the $25 processing fee, and you avoided the hassle of dealing with earnings calculations. Just make sure to adjust your HSA contributions for 2025 to account for that $35 that's being applied to next year's limit!

As a newcomer to this community, I have to say this thread has been incredibly educational! I'm currently going through a refinance on my 2016 mortgage and my lender mentioned something about "grandfathering" but didn't really explain what it meant for taxes. After reading everyone's experiences here, I'm definitely going to make sure my tax preparer understands these rules. It sounds like Sofia's situation could happen to anyone, and the difference in deductions could be significant for larger mortgages. One question for the group - should I be asking my mortgage lender for specific documentation about the grandfathering status when I close on my refinance? Or is it enough to just keep my original loan documents from 2016 along with the new refinance paperwork? Thanks to everyone who shared their knowledge and resources. This is exactly the kind of real-world guidance that's so hard to find elsewhere!

As someone who just joined this community, I'm blown away by how helpful and detailed everyone's responses have been! This thread perfectly demonstrates why I was drawn to this community in the first place - real people sharing actual experiences with complex tax situations. Sofia, I'm glad you got the clarification you needed about your grandfathered status. It's honestly shocking that your CPA got this wrong, especially since the rules around mortgage refinancing and grandfathering are so clearly laid out in IRS publications. This thread has made me realize I should probably double-check my own tax preparer's work more carefully. What strikes me most is how many people have similar stories about tax preparers misunderstanding these mortgage interest deduction rules. It makes me wonder how many taxpayers are missing out on legitimate deductions simply because their preparers aren't staying current with all the nuances of tax law changes from the Tax Cuts and Jobs Act. Thanks to everyone who shared resources like Publication 936 citations and practical tools. As a newcomer, having these specific references and real-world examples is invaluable for understanding not just this issue, but how to research and verify tax advice in general. This community is definitely a goldmine for navigating complex government services and tax situations!

Anyone know if Qualified Terminable Interest Property (QTIP) trusts have different tax rules? My spouse and I are updating our estate plan and our attorney mentioned QTIP but I'm not sure about the tax implications.

One thing to consider that hasn't been mentioned much is the "throwback rule" for complex trusts. If a trust accumulates income for several years and then makes a large distribution to beneficiaries, the IRS can "throw back" that income to prior years and tax it at higher rates, plus add interest charges. This can create a nasty surprise for beneficiaries who receive distributions from trusts that have been accumulating income. Also, watch out for state tax implications - some states don't recognize grantor trust status and will tax trust income at the state level even if it's flowing through to you federally. Others have no state income tax on trusts at all. The state where the trust is established, where the trustee resides, and where beneficiaries live can all potentially create tax obligations. If you're thinking about funding the trust with appreciated assets, remember that trusts don't get a stepped-up basis like inherited property does. So if you put stock worth $100k (that you bought for $20k) into a non-grantor trust, and the trust later sells it, the trust pays capital gains tax on the full $80k gain.
