MLP Tax Computation Engine

luc253/lucasandersen-ai

You'd reach for this when dealing with Master Limited Partnership tax calculations that need to reference actual IRS code. It exposes six tools covering basis tracking, Section 751 hot asset calculations, estate tax scenarios, and tax projections. The deterministic engine means you get the same results for the same inputs, which matters when you're documenting tax positions. Each calculation includes IRS citations so you can trace the logic back to source code. Built by Lucas Andersen and available over streamable HTTP, so you can integrate it without managing local processes. Useful if you're building fintech tools for energy investors or accountants who work with MLPs regularly.
