Did you check with your state's department of revenue? Sometimes they keep records of your federal entity classification. When I had a similar issue, I found that my state had documentation showing my federal S-Corp status because they needed it for state tax purposes. Might be worth checking!

I went through this exact same situation two years ago with my LLC's S-Corp election from 2017. The IRS sent me a letter claiming they had no record of my Form 2553, even though I had been filing 1120-S returns for years without any issues. Here's what worked for me: I requested my business tax account transcript online through the IRS website (you can get this immediately without waiting on hold). The transcript showed my entity classification code had been updated to "S" in 2017, which proved they had processed my election even though they claimed they didn't have it. I also gathered every single tax return, notice, and correspondence from the IRS since 2018 that showed they had been treating me as an S-Corp. This included looking at the entity type listed on my tax transcripts and any notices that referenced my business as an S-Corporation. When I sent all this documentation to the IRS with a cover letter explaining the situation, they quickly acknowledged that their records showed I had been properly classified as an S-Corp all along. The whole thing was resolved in about 3 weeks once I provided the right documentation. The key is showing the pattern of IRS acceptance through their own records rather than trying to recreate the original Form 2553 filing. Your consistent filing of 1120-S returns that were accepted creates a strong presumption that your election was valid.

I went through this exact situation last year and want to share what I learned after talking to a tax professional. The key thing to understand is that the 1099-K is just an information document - it doesn't automatically create taxable income. Here's what I did and what worked: 1. **Created a simple spreadsheet** with columns for: Item description, approximate purchase date, estimated original cost, sale price, and net loss. For items without receipts, I used reasonable estimates based on what similar items cost when I likely bought them. 2. **Used online resources** to verify reasonable original prices. For electronics, sites like Amazon price history or manufacturer MSRP data helped establish credible original values. For clothing, I looked at brand retail prices from the approximate purchase timeframe. 3. **Kept all eBay communications** - saved my listing descriptions, final sale prices, and any buyer messages that might help establish the personal nature of the items. 4. **Documented the personal use** - I noted in my spreadsheet how long I owned each item and that they were used personally, not held for investment or business purposes. The IRS understands that people clean out their homes and rarely make a profit on used personal items. As long as you're reasonable and honest with your estimates, you should be fine. The burden would be on them to prove your estimates were unreasonable, which is difficult for typical household items. Don't stress too much about perfect documentation - just be prepared to show these were legitimate personal items sold at a loss.

This is such a timely question - I just went through this exact situation! I sold about $1,800 worth of personal items on eBay this year (old video games, clothes, books, etc.) and was panicking about the 1099-K. Here's what I learned after doing a ton of research and talking to a tax preparer: **The 1099-K is NOT a tax bill** - it's just reporting what payment processors paid you. It doesn't mean that amount is taxable income. **For your specific questions:** 1. **Proving personal items sold at loss**: Create a simple spreadsheet showing item descriptions, estimated original purchase prices, sale prices, and the loss on each item. The IRS expects "reasonable estimates" - you don't need perfect precision. 2. **Original receipts**: You don't need receipts for everything. For items without receipts, document reasonable estimates based on typical retail prices when you purchased them. For example, if you sold a 2019 iPhone for $300, you can reasonably estimate it cost $800+ new. 3. **1099-K breakdown**: No, the 1099-K will just show your total gross payments. But you can download detailed sales reports from eBay that show individual transactions. **My approach**: I made a spreadsheet with columns for item, purchase year, estimated original cost, sale price, and net loss. For items I couldn't remember exact prices, I researched typical retail costs for those items during the year I likely bought them. The key is being reasonable and honest. The IRS knows most people lose money selling used personal items - they're not trying to tax you on legitimate personal losses.

Small tip from experience - make sure you keep all transportation receipts with notes about business purpose. For the Uber/taxi rides, I write directly on the receipt "transport to/from business speaking engagement" and snap a photo. Same for train tickets - write "business travel for paid speaking engagement" on them before filing. Seems obvious but these little notes saved me during an audit when I had to prove which trips were business vs personal.

Great question! You're absolutely right to think carefully about this allocation. Based on IRS Publication 463, you should go with option 2 - deduct 100% of the sleeper compartment and Uber costs since they would have been exactly the same whether your wife traveled alone or not. The key test is "what would it have cost if only the business traveler went?" Since a private sleeper compartment costs the same for one or two people, and the Uber rides would have been the same price, these are fully deductible business expenses. Just make sure to document everything well - keep the conference invitation showing the business purpose, all receipts, and maybe a brief note explaining why your daughter accompanied her (family visit, etc.) to show the trip wasn't primarily personal. One thing to add to what others mentioned about the hobby loss rule - since this appears to be related to your wife's professional field, even if expenses exceed the $750 honorarium, it's still a legitimate business deduction for a one-time engagement. The IRS only gets concerned about hobby losses when there's a pattern of losses over multiple years in the same activity.

Has anyone dealt with the "testing period" for the last-month rule with HSAs? I'm in a similar situation and thinking about using that rule, but I'm worried about what happens if I can't maintain HDHP coverage for the full testing period next year.

Congratulations on your marriage! Your timing is actually pretty good for HSA planning since you're changing jobs early in the year. Here's what I learned from my own similar situation: First, you absolutely don't need to roll over your existing HSA - it's your money forever. I kept mine with the old provider since they had better investment options and lower fees than my new employer's HSA. For contribution limits with marriage, it depends on your coverage types. If you both keep individual/self-only HDHP coverage through your respective employers, you can each contribute the full individual limit ($3,850 for 2025). However, if either of you has family coverage, you're limited to one family contribution total ($7,750 for 2025) that you split between your accounts. Since you're changing jobs, track your coverage months carefully. You can only contribute based on months you actually have qualifying HDHP coverage. So if you start your new job in May, you'd prorate your contributions accordingly. One tip: coordinate with your spouse on contribution timing if you're both maxing out. We set up automatic contributions but made sure to monitor them monthly to avoid any accidental over-contributions, especially since employer contributions count toward your limits too. The IRS Publication 969 has all the detailed rules if you want to dive deeper into the specifics!

I went through almost this exact same situation last year with my ceramic pottery hobby! After doing a lot of research and talking to my state's tax office, here's what I learned: You're absolutely doing the right thing by collecting sales tax. In most states, sales tax is required on tangible goods regardless of whether it's a hobby or formal business - the state just wants their cut of the transaction. For the income reporting piece, you can still treat this as hobby income since $580 from occasional craft fair sales clearly falls into hobby territory. The fact that you're collecting sales tax doesn't change that classification - they're separate tax issues entirely. When you file your taxes, you'll report the total income (including the sales tax portion) on Schedule 1 as "Other Income." Then when you remit the sales tax to your state, you can deduct that payment, so the sales tax portion essentially washes out on your federal return. The key is keeping good records of what you collected versus what you remitted to the state. Most states have pretty simple filing requirements for small sellers - mine only requires annual filing since I'm under their quarterly threshold. Don't stress too much about crossing into "business" territory at your current level. The IRS looks at things like profit motive, time invested, and business-like operations. Occasional craft fair sales of $580 is clearly hobby activity!

I've been dealing with this exact situation for the past two years with my handmade soap business (well, technically still a hobby). What I've learned is that the number of events itself doesn't automatically trigger business classification - it's more about the overall pattern and your intent. The IRS uses what's called the "nine factors test" to determine hobby vs business status. Things like: whether you operate in a businesslike manner, your expertise level, time and effort invested, expectation of profit, success in similar activities, history of profits/losses, amount of profits relative to losses, your financial status, and personal pleasure derived from the activity. For context, I've done 12-15 craft fairs per year for the past two years, making about $2,800 last year. I still classify as a hobby because: I only do weekend events, I don't advertise or have a website, I make soap primarily for my own enjoyment, the income doesn't support my household, and I don't keep detailed business records beyond what's needed for taxes. The key is being honest about your motivations and operations. If you're just doing more fairs because you enjoy it and want to share your husband's work (not because you're trying to build a profit-making enterprise), you're likely still in hobby territory. Just keep good records and be consistent in how you treat it on your taxes!
