How do you handle Form 8621 (PFIC)?
For each supported PFIC input, the engine calculates the selected QEF, MtM, or §1291 path and can generate a draft Form 8621 for review.
Updated September 2026
We classify each holding using a domicile + ticker-suffix heuristic during CSV / statement ingest, and show you each classification before the engine runs (per-row override is in progress).
For each PFIC you pick the election: Qualified Electing Fund (requires a PFIC AIS from the issuer), Mark-to-Market (only for publicly-traded PFICs), or default §1291.
Under §1291 the interest charge uses the IRS underpayment rate — we apply the published IRS rates from 2009 through the current year, not a flat estimate.
The self-serve package supports up to 25 Form 8621 drafts per return. Above that cap, the wizard routes you to specialist handling, with each holding kept separate.
