Why This MCP?
Tax season is stressful. You're juggling W-2s, 1099s, deductions, credits, and trying to figure out if you should itemize or take the standard deduction. You Google "SALT deduction limit 2025" and get 10 conflicting articles.
This package provides a deterministic local tax engine with two interfaces. Direct local CLI commands can collect, validate, import, and calculate supported tax facts without invoking an MCP client or model. The MCP server lets an AI assistant call the same engine, but tax facts entered into a cloud-hosted MCP client may be processed by that client's model provider. No IRS login or SSN is required.
It includes OBBB provisions modeled for TY2025, federal brackets, selected credits and deductions, and explicitly supported state-tax paths. Unsupported state calculations fail closed instead of applying a rough top-rate estimate.
🔒 Privacy Architecture
⚡ Getting Started
Option A: Direct local mode (recommended for taxpayer facts)
Install once, before entering any tax facts:
npm install --global irs-taxpayer-mcpRun the guided local questionnaire. It does not start MCP or invoke a model:
irs-taxpayer-mcp intake --output taxpayer-facts.jsonOr create and edit a strict local template:
irs-taxpayer-mcp template --output taxpayer-facts.json
irs-taxpayer-mcp validate --facts taxpayer-facts.jsonCalculate directly through the deterministic engine:
irs-taxpayer-mcp plan --facts taxpayer-facts.json
irs-taxpayer-mcp plan --facts taxpayer-facts.json --jsonShortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
