What it is
A tool for fund managers and fund administrators to send K-1 tax forms to limited partners, securely and automatically, without 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 the 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.
