Compare entity structures inside VS Code Copilot

The `calculate_tax_comparison` tool lets your developers run realistic tax scenarios without leaving their active workspace. It helps your team build accurate internal financial tools using real tax math. The agent evaluates federal and state liabilities instantly. It shares tax modeling capabilities across your entire engineering team.

Analyze S-Corp savings with this MCP Server

Use `evaluate_s_corp_savings_potential` to run the numbers on wages versus distributions. Finding the right time to elect S-Corp status requires detailed financial analysis. Your agent calculates the potential tax savings after accounting for mandatory reasonable salaries. It models these scenarios directly inside the chat interface.

Retrieve state tax rules instantly

The `get_state_tax_context` tool pulls the latest state-level tax environment data directly into your team's development cycle. State tax codes are notoriously complex and vary wildly across different regions. Your agent brings accurate local rates directly into your active files. It prevents your team from hardcoding outdated tax rates into your applications.
