It starts with the essentials — clean graphs and tables showing ordinary income, long‑term capital gains, deductions, taxes, credits, and IRMAA. These outputs are helpful, intuitive, and easy to use.
But the real power of the Tax Mapper is the Tax Map itself. With a sweep of what‑if inputs, it reveals how taxes and credits stack and shift as income changes. You can see marginal rate spikes, hidden cliffs, and planning windows in a way that traditional software simply doesn’t show.
Simple and focused, the Tax Mapper gives professionals a visual tool that cuts through noise and highlights the insights that matter most.
