Your agent uses the get_state_rate tool to fetch decimal tax rates for specific states. You can then ask it to organize these numbers into a comparison table or a list. This gives you a clear view of different tax burdens.

The results you get

What you can do with the data

The AI handles the data retrieval so you can focus on the math.

DATA

Direct rate retrieval

The AI pulls decimal tax rates for any state you name. You get the exact numbers without digging through state websites.

ANALYSIS

Side-by-side comparisons

Ask your agent to compare multiple states. It will present the rates in a format that makes differences obvious.

PLANNING

Tax burden modeling

Use the retrieved rates to estimate your tax liability in different locations. The AI handles the data gathering for your calculations.
