Short answer

How do I calculate top-up tax liabilities with my AI?

The results.

Where your tax data lands.

The AI processes your jurisdictional data into these specific outcomes.

DEFICIENCIES

Identified tax gaps

The AI flags every jurisdiction where the effective tax rate is below the required threshold. You get a list of specific locations that trigger Pillar Two requirements.

LIABILITIES

Calculated top-up amounts

The tool determines the exact dollar amount owed for each deficient jurisdiction. This provides the raw numbers needed for your tax filings.

REPORTS

Compliance summaries

Your agent organizes the findings into structured summaries. These reports highlight the total exposure across your entire global footprint.

HUMAN

Expert review needed

The AI identifies the math and the gaps, but you must review the final figures. You remain responsible for the legal accuracy of the tax filings.

FAQ

How this task behaves.

    Does the AI change my original tax spreadsheets?

    No. The AI reads your data to perform calculations, but it never modifies or deletes your source files.

  • 03

    What happens if my data is missing a jurisdiction?

    The AI can only calculate liabilities for the data you provide. It cannot invent or guess tax rates for missing entities.

  • 04

    Can I use this with Claude or Cursor?

    Yes, as long as your client is MCP-compatible, you can use this Connector with Claude, Cursor, Windsurf, or VS Code.
