This is exactly the kind of situation that can cause a lot of stress, but you're handling it the right way! I've dealt with similar K-1 corrections before and can confirm what others have said - for SSN-only corrections, you typically don't need the full 1065X process. One thing I'd add that hasn't been mentioned much: make sure to double-check ALL the other K-1s in your return while you're at it. I've found that when I make one data entry error like this, there's sometimes others lurking that I missed. Better to catch them all now rather than having to do multiple corrections later. Also, since you mentioned this is stressing you out - completely understandable! But this is actually one of the easier tax corrections to handle. The IRS deals with SSN corrections all the time, and as long as you're proactive about it (which you are), it should resolve smoothly. Your partner will appreciate you catching and fixing this quickly.

I went through this exact situation about 6 months ago with our LLC that's taxed as a partnership. You're absolutely right that you don't need to file a 1065X for just an SSN correction - that would be overkill for this type of error. Here's what worked perfectly for me: I created a new K-1 with the correct SSN, wrote "CORRECTED" in red ink at the top, and included a simple one-page letter explaining that only the SSN was incorrect and no dollar amounts were changed. I referenced our EIN and the tax year, then sent everything via certified mail to the same IRS processing center. The whole thing was resolved without any issues. My partner never heard anything from the IRS about it, and when I followed up a few months later, everything was properly updated in their system. One tip that really helped: I made sure to give my partner the corrected K-1 immediately so they could reference it if any questions came up on their personal return. Fortunately they hadn't filed yet, so it didn't complicate things on their end. Don't stress too much about this - it's really a straightforward correction and the IRS handles these SSN fixes all the time!

I'm confused by FreeTaxUSA's handling of this. When I tried to create a superseding return, the software only gave me the amended return option. Does anyone know if FreeTaxUSA actually supports filing superseding returns properly? Or do I need to manually handle this somehow?

Thanks for asking this question! I was in a similar boat last month and learned the hard way that there's a big difference. Just to add to what others have said - timing is really crucial here. Since you're still before April 15, you have the choice between superseding (complete replacement) or amending (correction to original). One thing I wish someone had told me: if your changes are significant (like major income additions or big deduction changes), superseding is usually the better route because it treats your situation as if you filed correctly the first time. But if it's just minor corrections, an amendment might be simpler. Also, keep in mind that if you go the superseding route, you'll need to paper file since most tax software doesn't handle the specific markings required for superseding returns. The IRS needs to see "SUPERSEDING RETURN" clearly marked at the top of a new 1040, not a 1040-X form. Have you determined what kind of changes you need to make? That might help decide which path is better for your situation.

Has anyone tried the buy-borrow-die strategy? I've heard this is what billionaires actually do. You buy appreciating assets, borrow against them for living expenses (no tax), and when you die your heirs get the stepped-up basis (avoiding capital gains). Seems like it would work for dividend stocks too if you just reinvest all dividends and borrow for cash needs.

Another strategy worth mentioning is tax-loss harvesting paired with dividend reinvestment plans (DRIPs). The ultra-wealthy systematically harvest losses throughout the year to offset dividend income, but they do it strategically. Here's what many people miss: you can sell losing positions to harvest the loss for tax purposes, then immediately reinvest the proceeds into a similar (but not identical) security to avoid wash sale rules. This creates tax deductions that directly offset your dividend income. For your $8k in dividends, if you can harvest $8k in losses, you've effectively made your dividend income tax-free for that year. The key is maintaining a diversified portfolio specifically for this purpose - holding similar stocks or ETFs that you can swap between. I also recommend looking into qualified small business stock (QSBS) if you're entrepreneurial. Dividends from qualifying small businesses can be completely tax-free up to certain limits. It requires more active involvement but can be incredibly tax-efficient for the right person. The real game-changer though is understanding that tax optimization is a year-round strategy, not something you think about in April. Start tracking your unrealized gains and losses monthly so you can make strategic moves throughout the year.

I think everyone is overlooking something important - if your daughter is a dependent on your tax return, her standard deduction is much lower than the regular standard deduction. It's limited to either $1,250 or her earned income plus $400, whichever is greater (but not more than the regular standard deduction). So with $2,700 in earned income, her standard deduction would be $3,100 ($2,700 + $400), which means some of her capital gains might be taxable! Make sure FreeTaxUSA is calculating this correctly.

You're absolutely right to be confused about FreeTaxUSA not recognizing the earned income! I went through this exact same issue with my nephew's landscaping income last year. The key is making sure you enter the dog sitting income in the right place. In FreeTaxUSA, you need to: 1. Go to Income → Business Income (Schedule C) 2. Enter "Pet Care Services" or similar as the business name 3. Report the $2,700 as gross receipts 4. Deduct any legitimate business expenses (supplies, mileage, etc.) Once you complete Schedule C, FreeTaxUSA will automatically calculate the self-employment tax AND recognize this as earned income for Roth IRA purposes. The software should then stop giving you errors about the Roth contribution. One thing to note - she'll owe about 15.3% self-employment tax on her net business income (around $413 if she has no deductible expenses), but this is separate from regular income tax. The good news is her total income is still under the standard deduction, so no regular income tax owed. The $1,422 in capital gains goes in the investment section and doesn't count toward Roth IRA eligibility, but it shouldn't push her into owing income tax either.

Has anyone actually successfully amended their return after paying the amount on a CP23? I'm in a similar situation but I already paid what they asked because I was scared of penalties, and now I'm trying to figure out how to get my money back by providing the missing documentation.

I'm dealing with a very similar situation right now! Also on a J-1 visa and just became a tax resident for 2024. The transition from nonresident to resident status creates so much confusion with the withholding forms. One thing I learned from my tax advisor is that you should definitely mention in your response letter that you're a tax resident filing Form 1040 even though you received a 1042-S. The IRS systems sometimes flag this as inconsistent, so explaining the visa status change and why the university issued the 1042-S (before they knew about your resident status) helps prevent further confusion. Also, if you have any documentation from your university showing when they became aware of your tax resident status, include that too. It helps explain the timeline and why the withholding was processed differently than your filing status. Good luck with your response! The stress is real but it sounds like you have a clear path forward.
