# lucasandersen.ai — MLP Tax Computation Platform

## About
lucasandersen.ai provides MLP (Master Limited Partnership) tax computation tools, a programmatic API, authoritative content, and a private-partnership basis reconstruction service. Built by Lucas Andersen (MS Finance; 20 years in asset management and institutional energy trading). All computations use IRS Partner's Instructions for Schedule K-1 (Form 1065) methodology with specific IRC section citations.
