Standardize Tax Calculations for Your Team

Get everyone on the same page with tax logic. This MCP calculates the taxable base under Brazil's Presumed Profit rules. Just give Copilot the revenue and activity type, and the `get_taxable_base` tool provides the correct base amount. By adding this MCP Server to your repo's .vscode/mcp.json, every developer gets access instantly. No more 'it works on my machine' issues with custom tax scripts.

Let Copilot Handle CIT and SCLL

Your team can use Copilot's agent to compute the full tax liability. It can call `calculate_cit_breakdown` for the Corporate Income Tax and `calculate_scll_liability` for the Social Contribution. The agent gets the exact numbers, including surcharges, and can inject them into tests, config files, or application code. This keeps your codebase consistent and accurate.

Generate Tax Summaries in VS Code

Stop manually creating tax reports for testing or documentation. The `generate_tax_summary_report` tool does it for you. It combines all the separate tax calculations into one clean summary. A developer can ask the agent for a full report for a given revenue number and get back a structured response. It's perfect for populating test fixtures or validating financial logic during development.

Common questions about Presumed Profit Tax Calculator MCP in VS Code Copilot

A team lead just needs to add this MCP's configuration to the .vscode/mcp.json file and commit it to your repository. Every team member with the Copilot extension will automatically get the tools.

Yes. Since the configuration is part of your repository, it works anywhere VS Code and Copilot run, including Codespaces. Your entire team will have a consistent toolset across local and cloud environments.

This public MCP uses standard presumptive margins. For custom logic or rates, you can fork the open-source code and host a private MCP for your organization.

Consistency. The shared configuration ensures every developer on your team uses the exact same vetted logic for tax calculations. This eliminates bugs from inconsistent, hand-rolled scripts.

The MCP only processes the gross revenue and activity type you provide. This data is used for the calculation and is not stored. Vinkius provides SOC 2 compliant infrastructure, and all communication is encrypted, meeting enterprise security standards.
