As a tax professional, I want to emphasize that for families with 5 children and your income level ($135,000 combined), filing jointly is almost certainly your best option. The key issue is that when married filing separately, the Child Tax Credit phases out starting at $75,000 per person instead of $150,000 for joint filers. With your combined income, one or both of you would likely exceed this lower threshold, reducing your total credits significantly. Additionally, filing separately would disqualify you from the Earned Income Credit entirely, which could be worth thousands with 5 qualifying children. You'd also lose access to education credits and the Child and Dependent Care Credit. I'd strongly recommend using tax software that can calculate both scenarios side-by-side so you can see the actual dollar difference. In my experience with large families at similar income levels, filing jointly typically saves $2,000-$4,000 compared to filing separately.

I've been through a similar situation with 4 kids and can confirm what others are saying - filing jointly is almost always better for larger families. What really opened my eyes was when I actually ran the numbers both ways. Filing separately would have meant we lost about $3,200 in total benefits! The biggest hit was losing the Earned Income Credit completely, plus our Child Tax Credits were reduced because of the lower phase-out thresholds. One thing I'd add is that you can't just arbitrarily decide who claims which kids when filing separately. If you both live with all 5 children full-time, you'd need to follow IRS tiebreaker rules, and typically the parent with higher income would claim all the dependents anyway. The math gets complicated with multiple credits interacting, but with 5 kids and your income level, I'd be shocked if filing separately saved you anything. Definitely worth double-checking with tax software that can show both scenarios, but I'm confident you'll find joint filing is the way to go.

Another resource that might help is checking with your state's Department of Labor or Workforce Development office. Since you mentioned the company closed suddenly, they may have had to file WARN Act notices or other closure documentation that would include their EIN. These departments also handle final wage claims and often maintain records of businesses that shut down unexpectedly. You could also try searching for the company on EDGAR (the SEC's database) if they were incorporated or had any public filings. Even small companies sometimes have basic registration documents that include their EIN. If you had any work-related expenses that you claimed on previous tax returns (like home office deductions or business meals while employed there), check those old tax documents - sometimes people include employer EINs in their record-keeping without realizing it. Lastly, don't forget to check any unemployment correspondence you received. When you filed for unemployment benefits, the state would have needed to verify your employment, and those documents often reference the employer's EIN for identification purposes.

I went through almost the exact same situation two years ago when my employer, a small consulting firm, just vanished overnight. Here's what ultimately worked for me: First, I called my state's unemployment office (since you mentioned filing for unemployment). They were incredibly helpful and had the EIN on file from when I applied for benefits. The representative was able to give it to me over the phone once I verified my identity. Second, I found the EIN on an old direct deposit setup form that was buried in my email. If you search your email for terms like "direct deposit," "payroll," or even just the company name, you might find setup documents from when you were hired. One thing that really saved me was discovering that our payroll was handled by a third-party company (Gusto in my case). Even though the main company was gone, the payroll service still had all the records. You might be able to identify your payroll provider by looking at the sender of your paystub emails or any payroll-related communications. Don't stress too much about the deadline - the IRS is actually pretty understanding about situations like this when you can show you made good faith efforts to get the information. You can always file for an automatic extension if needed while you track down the EIN. Form 4868 gives you until October to file, which should be plenty of time to sort this out.

If you received Form 1098-T from your school before it closed, make sure you keep that for your records too. It shows what you paid for qualified education expenses and will help determine if these reimbursements are taxable or not.

This is a great question that unfortunately comes up more often these days with school closures. The key thing to understand is that Department of Education reimbursements typically fall into two main categories with different tax treatments: 1. **Direct tuition/fee reimbursements** - These are generally NOT taxable since you're just getting back money you already paid out of pocket. Think of it like returning an item to a store. 2. **Living expenses/housing allowances** - These ARE typically taxable income since they represent money you received for expenses that weren't qualified education expenses. The tricky part is that many reimbursement letters don't clearly specify which category applies. I'd strongly recommend calling the Department of Education's Federal Student Aid Information Center at 1-800-433-3243 to get written clarification on exactly what your $4,300 represents. Also keep in mind - if you claimed education tax credits (American Opportunity Credit, etc.) in previous years for expenses you're now being reimbursed for, you may need to "recapture" those credits on your 2025 return, which could result in additional tax owed. Save all documentation and consider consulting with a tax professional if the amounts are substantial. Better to get it right from the start than deal with IRS issues later!

Yes, definitely document those first 3 months! When you file MFS after living together for part of the year, you need to show how you're splitting shared expenses like mortgage interest, property taxes, and other itemized deductions. The IRS wants to see a reasonable allocation method - whether it's 50/50, based on income percentage, or actual payment records. For the months you lived together, gather bank statements, receipts, and any records showing who paid what. Even if your record keeping wasn't perfect, recreate what you can with bank statements and credit card records. The key is having a consistent, logical method for splitting shared expenses that you can explain if questioned. Also make sure you're not both claiming the same deduction - that's a huge red flag. If you paid the mortgage in January but your ex paid it in February, document that clearly. The IRS computers will catch duplicate claims between spouses pretty quickly.

I went through this exact situation during my separation two years ago and it was incredibly stressful. The rule about both spouses having to use the same deduction method (standard vs itemized) when filing MFS is really frustrating when you can't communicate well with your ex. What helped me was creating a simple comparison chart showing both scenarios - what our combined tax liability would be if we both took standard deduction vs. if we both itemized. I presented this to my ex as "here's what's financially best for both of us" rather than making it about what I wanted. Sometimes framing it as a purely mathematical decision rather than a personal preference can help reduce conflict. Also, if your ex insists on itemizing even when it's not optimal for both of you, document that decision. During my divorce proceedings, my attorney was able to use similar instances of financial non-cooperation as examples of unreasonable behavior. It didn't change the immediate tax situation, but it did help establish a pattern that was relevant later. The most important thing is to file correctly according to whatever method you both end up using. An incorrect filing that gets flagged by the IRS will create way more problems than paying a bit more in taxes this year.

This entire discussion has been incredibly enlightening, and I want to add a perspective from someone who's been burned by this exact issue. Last year, I had a client with a hedge fund investment where we took the above-the-line deduction for management fees based on their K-1 characterization as Section 162 expenses. Fast forward to this year - the client got audited, and it turns out the fund's "trader status" claim was completely bogus. They were making maybe 2-3 trades per month and holding positions for 6+ months at a time. The IRS reclassified all the expenses as investment expenses, which meant they were subject to the 2% AGI floor (suspended, but still problematic for audit purposes). What made it worse was that the fund provided zero documentation when we requested support for their trader status claim during the audit. Their response was basically "trust us, we qualify" with no trading statistics, no legal analysis, nothing. We ended up having to concede the position and pay penalties and interest. The lesson I learned: if a fund can't immediately provide detailed documentation supporting their trader status claim - including specific trading frequency data, holding period analysis, and legal basis for their position - don't take the risk. The audit exposure far outweighs any potential benefit, especially with miscellaneous itemized deductions currently suspended anyway. I've now adopted a policy similar to what others have described here: comprehensive documentation requirements upfront, or we treat it conservatively as investment expenses. No exceptions. My malpractice carrier loves this approach too!

As someone who's been dealing with hedge fund taxation for over a decade, I want to emphasize that the original poster's instinct to be cautious is absolutely correct. The lack of clear IRS guidance on this issue isn't accidental - it's because the rules are highly fact-specific and many funds are making unsupported claims. I've seen this pattern repeatedly: funds claim trader status to justify above-the-line treatment of management fees, but when you dig into their actual trading patterns, they don't come close to meeting the "frequent, regular, and substantial" standard established in cases like Groetzinger and Chen v. Commissioner. The red flags I always look for: 1) Generic trader status explanations that could apply to any fund, 2) Inability to provide specific trading frequency statistics, 3) Average holding periods measured in weeks rather than days, 4) No documentation of a Section 475(f) election, and 5) Marketing materials that emphasize long-term investment strategies. My recommendation: Don't take these deductions unless the fund can provide a detailed legal memorandum explaining how they meet each prong of the trader status test, along with supporting trading data. With miscellaneous itemized deductions suspended through 2025, there's literally no benefit to taking the aggressive position right now, but plenty of audit risk. The stories shared in this thread about funds providing zero documentation during audits should be a wake-up call for anyone considering these positions. Protect yourself and your clients by requiring bulletproof documentation upfront.
