PFIC portfolio analyzer

Already filled in your holdings — on Atamatax or somewhere else? Re-enter your positions here and this tool runs the same real calculation engine a paid return uses: which are PFICs, the actual §1291 tax on any you sold this year, and which IRS forms it triggers. No account, nothing saved — this is the exposure your software may have missed.
