What it is

A tool for fund managers and fund administrators to send K-1 tax forms to limited partners, securely, automatically, and without manually emailing PDFs one at a time.

Built for the annual tax-season ritual every fund manager hates: collecting K-1s from your tax preparer, matching them to LPs, sending each one individually, dealing with bounces, fielding "did you send mine?" emails. This automates the send.

How it works

  • Upload K-1s, bulk upload all PDFs from your tax preparer
  • Match to LPs, automatic matching by name and EIN, with manual review for edge cases
  • Send, each LP gets a personalized email with their K-1 attached, sent from your domain
  • Track, see who opened, who downloaded, and resend if needed
