A mark-to-market election under §1296 generally recognizes the yearly change in eligible PFIC stock's fair market value rather than waiting for a sale under §1291. It can be useful only when the stock is marketable under the statutory rules and the election is properly made.
Marketable stock is a legal eligibility test
Public quotation or a broker valuation does not by itself settle eligibility. The PFIC stock must satisfy the applicable regular-trading or other marketable-stock requirements. Atamatax asks for the security and market facts rather than offering mark-to-market for every foreign fund.
Annual income, loss limits, and basis
The annual fair-market-value increase is generally ordinary income. A decrease can produce ordinary loss only to the extent of unreversed prior mark-to-market inclusions; additional loss follows different treatment. Basis is adjusted for recognized income and loss, which affects a later disposition.
What a late election does not fix automatically
If the stock was held before the election, prior non-electing PFIC years can continue to matter. A complete workflow needs the acquisition date, earlier Forms 8621, election year, annual values and transactions.
Check the holding before selecting mark-to-market
Run the security through the PFIC workflow, establish marketability and add annual values. Unsupported eligibility or earlier-year questions are surfaced for review.
