I went through this exact same situation two years ago with my daughter's EIC claim. The SEIC-F1040-506 error is incredibly frustrating because even though the amendment has been filed and accepted, the IRS systems don't communicate with each other in real time. What really helped me was calling the IRS Taxpayer Advocate Service (TAS) at 1-877-777-4778. They can sometimes expedite the processing of your return when there's a clear documentation trail showing the other parent filed an amendment to correct the duplicate claim. You'll need to have your ex's amendment confirmation number and be able to explain the timeline of events. Also, when you do paper file, make sure to write "DUPLICATE SSN - AMENDMENT FILED" in red ink at the top of your Form 1040. This helps the processing center understand immediately what's happening instead of your return sitting in a pile for weeks while they figure out the issue. The whole process is a nightmare, but with proper documentation and following up with TAS if needed, you should get it resolved within 8-10 weeks instead of the usual 16+ weeks for complicated amendments.

I'm dealing with a very similar situation right now! My ex-husband claimed our daughter on his EIC when it was my year according to our divorce decree. He filed an amended return last month to remove her, but I'm still getting the same SEIC-F1040-506 rejection. Reading through all these responses has been incredibly helpful. I think I'm going to try the Taxpayer Advocate Service route that Noah mentioned, since I have all the documentation (amendment confirmation, custody agreement, rejection notices). The idea of writing "DUPLICATE SSN - AMENDMENT FILED" in red ink on a paper return is genius - I never would have thought of that. Has anyone had success with TAS actually expediting these types of cases? I'm worried about waiting 8-10 weeks for processing since I really need my refund to catch up on some bills. The whole situation is so frustrating because we did everything right, but the IRS systems can't keep up with the reality of divorced parents trying to follow their custody agreements.

I'm in a very similar situation - been in the US for 4 years and just discovered FBAR requirements. Like you, I've been diligent about my regular tax filings but had no idea about these foreign account reporting obligations. From reading through all these responses, it sounds like the Streamlined Filing Compliance Procedures are definitely the way to go rather than just starting to file FBARs now. The fact that multiple people have mentioned that simply filing current FBARs without addressing past years could create bigger problems is really concerning. I'm particularly worried because my foreign accounts have fluctuated above and below the $10,000 threshold over the years, so I'm not even sure which years I should have filed. Has anyone dealt with a situation where you're not entirely certain which years triggered the filing requirement? I kept good records of my account balances, but I'm realizing I need to go back and calculate the maximum balances for each year using the correct Treasury exchange rates. The suggestions about getting professional help are making a lot of sense to me now. This seems too complex and high-stakes to risk getting wrong on my own.

I want to emphasize something that hasn't been mentioned enough in this thread: the importance of acting quickly once you discover your FBAR obligations. The IRS has a 6-year statute of limitations for FBAR violations, but this clock doesn't start ticking until you actually file the required forms. What this means practically is that every year you delay addressing your missing FBARs, you're potentially adding another year of exposure to penalties. The Streamlined Filing Compliance Procedures that everyone has mentioned are definitely your best option, but they require you to file FBARs for the past 6 years regardless of when you discovered the requirement. I've seen situations where people discovered their FBAR obligations but then spent months researching and deliberating, only to realize they could have saved themselves a lot of stress by acting sooner. The non-willful penalties under the Streamlined procedures are much more manageable than the potential willful penalties if this drags on and the IRS views any continued delay as intentional non-compliance. Given that your foreign accounts are legitimate, properly maintained in your home country, and you've been reporting the income on your US tax returns, you have a strong case for non-willful treatment. Don't let overthinking this situation work against you.

3 Has anyone ever just put the box, number 1 amount into boxes 3 and 5 when filing? I had a similar issue couple years ago and that's what my tax guy told me to do since that's typically what those boxes should match anyway. I didn't get audited or anything.

This is actually a pretty common issue with small businesses - I've seen it happen several times. Your instinct is right to be concerned about just putting zeros when you know taxes were withheld. Here's what I'd recommend: First, definitely contact your employer ASAP to request a corrected W-2 (Form W-2c). They're legally required to issue one when there are errors. In the meantime, gather your final paystub from 2024 - it should show your year-to-date totals for Social Security and Medicare wages and withholdings. If you can't wait for the corrected W-2, you can file Form 4852 (Substitute for Form W-2) using the correct information from your paystub. Just make sure to attach documentation explaining the discrepancy. The IRS would rather you report accurate information than what's on an incorrect W-2. Don't just copy Box 1 into Boxes 3 and 5 without verification - while they're often the same, there can be legitimate differences depending on your benefits and deductions. Check your paystub first to confirm the actual amounts.

This question comes up a lot! I recommend using the IRS Interactive Tax Assistant tool. Just google "IRS filing status tool" and it walks you through a series of questions to determine if you qualify for HOH. Much better than guessing or getting random advice online.

I work as a tax preparer and see this situation frequently. Yes, multiple people in the same physical address can absolutely claim Head of Household status as long as they each meet the requirements independently. The key is understanding that "household" for tax purposes doesn't mean the physical building - it refers to your financial responsibility for maintaining a home where you and your qualifying person live. Each parent supporting their own children can constitute a separate "household" even under one roof. For your cousin's situation, they should both be able to claim HOH if they each: - Are unmarried at year-end - Have qualifying children living with them more than half the year - Pay more than half the cost of keeping up their respective households The 50/50 split of shared expenses (utilities, rent/mortgage) is fine. They just need to track that each person's total contribution (their share of common expenses PLUS their children's individual expenses) exceeds half of what it costs to maintain their living situation. Keep good records and consider consulting a tax professional if the numbers are close, but this is definitely allowed by the IRS.

Has anyone used a 1031 exchange for a property that was converted from personal to rental? I'm in a similar situation but with about $200k in expected gains and wondering if I can defer by purchasing another investment property.

This is exactly the kind of situation where proper documentation becomes crucial! Since you're dealing with a mixed-use property, make sure you have clear records of when you converted it to rental use (September 2023) - lease agreements, advertising records, any improvements made specifically for rental purposes, etc. One thing to keep in mind is that the IRS typically requires the property to have been used for business purposes for at least 2 of the last 5 years to qualify for certain tax benefits. Since you only rented it for about 6 months, this might limit some of your options. Also, don't forget about potential state tax implications! Some states have different rules for capital gains on converted properties, so you'll want to check your state's specific requirements too. The federal calculation is complex enough, but state rules can sometimes throw additional curveballs into the mix.
