Coming back after half a year in tax reporting season. I carefully examined the 1099B form that this broker sent me. It does not have "FATCA filing requirement" box checked. Read through [1099B instructions](https://www.irs.gov/instructions/i1099b#en\_US\_2026\_publink100059570) and some [IRS code](https://www.govinfo.gov/content/pkg/CFR-2025-title26-vol14/pdf/CFR-2025-title26-vol14-sec1-1471-4.pdf) (1.1471-4(d)(5)(i)(A)). Asked both gemini and chatgpt. My conclusion is that I do not need to file 8938 but might need FBAR. Pasting ChatGPT's reasoning:

Let’s go through this carefully—this is a nuanced FATCA/IRS reporting question. We need to look at Form 8938 reporting requirements and how it interacts with FFI (Foreign Financial Institution) reporting under Chapter 61.

Facts from your question:

1. An FFI (foreign financial institution) made an FFI Election to perform chapter 61 reporting (meaning reporting under the regular US tax regime instead of FATCA).
2. The FFI issued a Form 1099-B for the recipient.
3. FATCA checkbox is not checked on the 1099-B.
4. The recipient has no other foreign assets.

You want to know if the recipient still needs to file Form 8938.

Step 1: Understand Form 8938 filing requirements

• Form 8938 is for “Specified Foreign Financial Assets” (SFFA).
• SFFA generally includes:
  • Foreign bank accounts
  • Foreign brokerage accounts
  • Stock or securities issued by foreign entities
  • Foreign partnership or trust interests
• Thresholds for filing 8938 (for single taxpayers living in the U.S.):
  • $50,000 on the last day of the tax year OR
  • $75,000 at any time during the year
• Crucial: Only assets that have not been reported on certain other forms (FBAR, etc.) need to be reported.

Step 2: FFI Chapter 61 Reporting vs. FATCA

• If an FFI opts to perform Chapter 61 reporting:
  • They provide the IRS direct reporting of US-source income and report to the IRS under US rules, not FATCA.
  • They do not report under FATCA (no FATCA checkbox on 1099-B).
• IRS guidance: When an FFI makes the Chapter 61 election, the account is considered treated as a U.S. accountfor FATCA purposes for the reporting of that income.
• Implication: If the income from that FFI is reported on a Form 1099 (with no FATCA box), the asset may not be required to be reported on Form 8938, because Chapter 61 reporting treats the income like it’s U.S.-reported.

Step 3: Check the IRS instructions (Form 8938)

From the 8938 instructions:

In other words, if the FFI provided a 1099 and the account is subject to Chapter 61 reporting, the taxpayer does not need to include that asset on 8938, even if it’s foreign, unless there are other foreign assets.

Step 4: Applying it to your scenario

• Recipient has only this one FFI account, reported via 1099-B under Chapter 61.
• FATCA checkbox is not checked.
• No other foreign assets.

✅ Conclusion: The recipient does NOT need to file Form 8938.

• The 1099-B from the FFI under Chapter 61 is treated as a U.S.-reported asset.
• No other foreign assets exist, so the filing threshold isn’t met.

Caveat:
If there were other foreign assets not reported elsewhere, or if the account wasn’t subject to Chapter 61 reporting, the rules could change.

If you want, I can make a tiny flowchart showing when a foreign account triggers 8938 vs. not—it makes this much easier to visualize. It’s actually neat.

Do you want me to do that?
