Has anyone tried just calling TD Ameritrade directly? Even though they were acquired by Schwab, they might still have access to their older systems with your historical data. Sometimes these companies maintain separate record-keeping systems for years after an acquisition.

Another option if you're still stuck is to check with your tax preparer or CPA if you used one during the years around when you purchased the stock. Sometimes they keep copies of old tax returns that might have records of dividend income from that stock, which could help establish when you owned it and potentially give clues about your purchase timing. Also, don't forget to check your old bank statements if you still have access to them online. Many banks keep records going back 7+ years, and you might find the withdrawal or transfer that funded the stock purchase. Even if it doesn't give you the exact cost basis, it could help narrow down the purchase date and amount, which you can then cross-reference with historical prices. The key thing is to document whatever method you use and keep records showing you made a good faith effort. The IRS is generally reasonable about these situations when you can show you tried to find the actual information.

Something others haven't mentioned - make sure you're not violating any terms of your employment contract by doing these consultations. Some companies have non-compete clauses or require approval for outside work. Last thing you want is tax records that show you were doing something your employer prohibits!

Don't forget about quarterly estimated tax payments! I do similar expert calls and got hit with an underpayment penalty my first year because I wasn't making quarterly payments. Since you don't have taxes withheld from these payments like your regular job, you're supposed to pay as you go.

Has anyone tried switching from TurboTax to a different tax software? I had this exact problem last year and found that H&R Block's software actually explained the earned income calculations better and showed me why my Schedule C income wasn't qualifying.

This is a really common confusion point! I went through the exact same thing last year. The key issue is that when you enter 1099-NEC income as Schedule C business income, TurboTax calculates your self-employment tax (15.3% on 92.35% of your net profit), and then it uses your NET earnings from self-employment for the earned income credits - not your gross 1099 amount. So if you received $5,000 on your 1099-NEC, after self-employment taxes and the deduction for half of SE tax, your actual "earned income" for credit purposes might only be around $4,200-$4,300. This reduced amount could be pushing you below the income thresholds needed to qualify for maximum credits. When you mistakenly entered it as W-2 income, TurboTax treated the full amount as earned income without any SE tax deductions, which is why you got different credit amounts. Make sure you're entering it correctly as Schedule C income - the credits should still apply, but the net amount after SE taxes is what counts toward your eligibility calculations.

Something important to consider - make sure you're keeping VERY detailed logs of your time spent on both properties. I learned this the hard way during an audit. The IRS wanted to see documentation of all hours claimed for material participation. I recommend creating a spreadsheet with dates, times, description of activities, and which property each activity relates to. Take photos of yourself doing work when possible. Keep all emails with contractors, guests, etc. The more documentation you have, the better position you'll be in if questioned.

Make sure you understand the different tests for material participation. You mentioned the 100 and 500 hour thresholds, but there are actually 7 different tests, and you only need to meet ONE of them to qualify: 1. You participate for more than 500 hours 2. Your participation constitutes substantially all participation 3. You participate for more than 100 hours and no one else participates more 4. The activity is a significant participation activity and your total participation in all SPAs exceeds 500 hours 5. You materially participated for any 5 of the preceding 10 tax years 6. The activity is a personal service activity and you materially participated for any 3 preceding tax years 7. Based on all facts and circumstances, you participate on a regular, continuous, and substantial basis for more than 100 hours

This thread has been incredibly helpful! I'm on an H1-B visa and have been stuck on Form 8802 for weeks. After reading everyone's experiences, I finally understand that line 4a is about tax classification, not immigration status. Just to confirm my understanding: since I've been in the US for 4 years and clearly pass the substantial presence test, I should check "Individual U.S. citizen/resident alien" even though I'm not a citizen. Then in line 4e, I'll put "H1-B" with my status start date. For documentation, I'm planning to include: copy of my H1-B visa, I-94, most recent Form 1040 showing I filed as a resident alien, and a brief cover letter explaining my tax residency status. Does this sound like the right approach based on everyone's successful applications? Really appreciate all the detailed experiences shared here - this community is a lifesaver when the IRS instructions are so confusing!

Do the following for line 4a: ✅ Check “Individual.” ✅ Check “Other U.S. resident alien.” ✏️ In “Type of entry visa,” enter the visa you used to enter the U.S. ✏️ In “Current nonimmigrant status,” enter your current visa type (for example, H-1B). 📅 In “Date of change,” enter the date you received your current visa status.
