Asset-Location Swap Planner

A web app that models and operationalizes tax-aware asset-location swaps across taxable and retirement accounts (e.g., sell equities in taxable, buy equivalent equities in 401(k), move T-bills/bonds to 401(k)) while keeping target allocation constant. It generates a step-by-step execution plan, tracks drift, estimates tax impact, and produces an audit-friendly trade log and rationale you can share with your CPA.

Target customer

High-net-worth retirees (and their CPAs/fee-only planners) managing multi-account portfolios with meaningful interest income in taxable accounts (e.g., T-bill ladders, bond funds) and ongoing withdrawals.

Problem-solution fit

Customers need a reliable way to capture recurring tax savings from asset location without accidentally changing risk exposure or creating messy documentation. The product translates a confusing forum-discovered tactic into repeatable workflows, with projections, guardrails, and records that reduce errors and CPA back-and-forth.
