Team-wide tax calculation tools

Commit `calculate_tax_liability` to your repo's configuration so every team member has the same engine. It ensures everyone uses identical tax logic for their tasks. Consistency matters when you are building financial tools. You remove the risk of developers using different versions of tax math.

Compare business structures with Copilot

Use `compare_business_structures` to help your team visualize tax burdens for different entities. It provides a clear summary that you can reference in your documentation. You save time by not explaining tax rules repeatedly. The tool gives your team the same data every time they ask.

Centralized state rate management

Call `get_state_tax_rate` to keep your team's code updated with the latest state figures. It pulls data directly, so you do not have to update constants manually. Your team builds faster when they rely on a single source of truth. It integrates directly into the VS Code Copilot chat window.
