How do you handle Form 8621 (PFIC)?

Every PFIC gets its own Form 8621 with QEF, MtM, or §1291 — the §1291 path uses the real IRS interest-rate table from 2009 onwards.

We classify each holding using a domicile + ticker-suffix heuristic during CSV/Plaid ingest. You can override the classification per-row before the engine runs.

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 compounded daily — we use the real quarterly-published rates from 2009 through the current year, not a flat estimate.

We support up to 25 Form 8621 filings per return. Beyond that we aggregate where the regulation allows or refer you out.
