# Pillar Two Compliance MCP > Global Effective Tax Rate & Pillar Two Compliance calculates a company's total tax exposure under OECD Pillar Two rules. It identifies if local tax rates fall below the 15% minimum, determines the weighted average global tax rate, and provides the final consolidated tax liability for multinational operations. ## Overview - **Category:** finance - **Price:** Free - **Tags:** oecd, pillar-two, tax-compliance, global-minimum-tax, finance-engine ## Description Running complex international tax compliance used to mean spending weeks cross-referencing dozens of national tax codes and building massive pivot tables. This MCP handles that heavy lifting. It gives your AI agent a specialized engine to calculate exactly where a company stands against global minimum tax rules, specifically the OECD Pillar Two framework. You can determine if any single jurisdiction's effective rate drops below 15%, flagging the deficiency immediately. Better yet, you don't have to look at countries individually; the MCP calculates the weighted average global ETR and gives you one number for the entire enterprise’s tax obligation. Vinkius hosts this MCP, letting your agent access these critical international computations without needing specialized database connections or complex API calls. It simply tells you what the total effective tax burden is. ## Tools ### calculate_consolidated_burden Calculates the final total tax obligation for the entire enterprise, including any necessary top-up adjustments. ### calculate_global_etr Finds the single weighted average tax rate for all of your company’s global operations combined. ### calculate_jurisdictional_deficiency Checks if a specific country's tax rate is below the 15% minimum and calculates the resulting top-up tax required. ## Prompt Examples **Prompt:** ``` Check if Ireland's 12.5% tax rate requires a top-up tax for a profit of $1,000,000. ``` **Response:** ``` Yes, Ireland's rate is below the 15% threshold. The top-up tax due is $25,000. ``` **Prompt:** ``` Calculate the global ETR for jurisdictions with profits of $500k at 10% and $500k at 20%. ``` **Response:** ``` The global effective tax rate for these operations is 15.0%. ``` **Prompt:** ``` What is my total consolidated tax burden if I have $10,000 in local tax and $5,000 in top-up tax? ``` **Response:** ``` Your total effective liability is $15,000. ``` ## Capabilities ### Determine Local Tax Deficiencies Checks a specific country's local tax rate against the 15% global minimum and calculates any resulting top-up tax owed. ### Calculate Global Weighted Average Rate Finds the single, overall effective tax rate for all of your company’s international operations combined. ### Determine Total Tax Liability Sums up every local tax payment and every required top-up adjustment to show the final total tax burden across the enterprise. ## Use Cases ### Evaluating New Market Entry A company is looking at opening an office in Country X. Before committing, they ask their agent to run `calculate_jurisdictional_deficiency` on Country X's current tax rate and local profitability data. This tells the CFO immediately if the new operation will trigger a top-up tax liability, allowing them to adjust pricing or structure before filing. ### Annual Compliance Check The finance team needs to check their global compliance status for the fiscal year. They use `calculate_global_etr` with data from all operating subsidiaries. This gives a single benchmark rate, which they then feed into `calculate_consolidated_burden` to see the total group tax payment due. ### Restructuring Due Diligence A corporate team is considering moving operations between two countries. They use `calculate_global_etr` first, then run targeted checks using `calculate_jurisdictional_deficiency` on both the departure and arrival countries to map out all potential tax changes before making a decision. ### Audit Preparation The compliance department needs to prove their total tax liability for an audit. They combine local tax records with top-up figures and run `calculate_consolidated_burden` to generate an auditable, single figure of the required payment. ## Benefits - Pinpoint local risks instantly. Instead of guessing, use `calculate_jurisdictional_deficiency` to confirm exactly where a country's effective rate falls under the 15% threshold and calculate the specific top-up tax amount. - Get an immediate global picture. Run `calculate_global_etr` to find one weighted average tax rate for all your countries, allowing you to compare performance across entire regions quickly. - Confirm total liability in a single step. Use `calculate_consolidated_burden` when you need the final number—the sum of local taxes plus every required top-up adjustment for the whole enterprise. - Reduce audit risk by standardizing calculations. Your agent runs these complex computations against OECD rules, ensuring consistency whether you are checking one country or twenty. - Test multiple scenarios fast. You can plug in hypothetical profits and different tax rates to see how adjusting a single jurisdiction affects the total burden. ## How It Works The bottom line is that this MCP takes a messy pile of country-specific financial data and converts it into clear compliance numbers for global risk assessment. 1. First, you feed your agent the financial data for a specific country or region. The tool then checks if that local effective tax rate meets the 15% global minimum. 2. Next, you can provide input for all operating jurisdictions to calculate the weighted average ETR across every location globally. 3. Finally, the system aggregates these results to give one figure: the total consolidated tax burden for your entire multinational group. ## Frequently Asked Questions **What is the purpose of the `calculate_jurisdictional_deficiency` tool?** It determines if a specific country's tax rate is below the 15% OECD threshold and calculates the resulting top-up tax liability based on the profit amount. **How does `calculate_global_etr` work?** The tool calculates a single weighted average tax rate for all provided jurisdictions by dividing the total taxes paid by the aggregate profit. **Can I calculate my total enterprise tax burden?** Yes, using the `calculate_consolidated_burden` tool, you can sum all local taxes and top-up taxes to find your total effective liability. **What data structure does `calculate_global_etr` require when calculating for multiple countries?** The tool needs a structured array of objects, where each object must contain both the profit base and the local tax rate for one jurisdiction. This format allows the MCP to correctly calculate the weighted average across all reported operations. **If `calculate_jurisdictional_deficiency` returns zero, what does that mean about compliance?** A result of zero means the specific country's local tax rate meets or exceeds the 15% global minimum threshold. You don't need to account for any top-up taxes in that jurisdiction. **Are there usage limits when running `calculate_consolidated_burden`?** While designed for high volume, continuous heavy use may trigger temporary rate limits. Always monitor your Vinkius dashboard for real-time quota status before submitting a large batch of calculations. **Can I run any tool, like `calculate_global_etr`, using data from previous fiscal years?** Yes, the MCP supports historical analysis. You must ensure your input payload includes the correct reporting period identifier and all necessary financial statements for the desired tax year. **How secure is the connection when utilizing this MCP for sensitive tax data?** Security relies on standard OAuth protocols managed by Vinkius. Your AI client never sees raw credentials; it uses limited permission tokens to execute specific calculations only.
