AI Tax Compliance: Global Tax Automation

BEPS 2.0 Pillar Two: The Global Minimum Tax Framework

Pillar Two operates through a set of interlocking rules designed to ensure MNEs pay a minimum 15% effective tax rate in every jurisdiction where they operate. The Income Inclusion Rule (IIR) requires the ultimate parent entity to include in its income a top-up tax amount for any constituent entity jurisdiction where the effective tax rate is below 15%. The Undertaxed Profits Rule (UTPR) operates as a backstop, allocating top-up tax to jurisdictions where constituent entities are located when the IIR has not been applied by the ultimate parent jurisdiction. Qualified Domestic Minimum Top-up Taxes (QDMTTs) allow jurisdictions to apply the top-up tax domestically before the IIR or UTPR apply, and many jurisdictions including India, the UK, and several EU member states have enacted QDMTTs. The GloBE Rules require ETR calculations using GloBE income (financial accounting net income adjusted for specific items) divided by adjusted covered taxes (current tax expense plus deferred tax adjustments). The calculations are extraordinarily complex: GloBE income adjustments address stock-based compensation, policy disallowed expenses, prior period errors, accrued pension costs, and dozens of other items specified in the Model Rules and Administrative Guidance. Substance-based income exclusions (SBIE) carve out 5% of eligible payroll costs and 5% of tangible asset carrying values, with transitional percentages declining over ten years. Safe harbor provisions, including the Transitional CbCR Safe Harbour based on Country-by-Country Report data and the Permanent Safe Harbour, provide simplified compliance pathways for jurisdictions meeting specified conditions. AI compliance platforms automate these intricate calculations, ingesting financial data from all constituent entities, applying GloBE adjustments, computing jurisdiction-level ETRs, evaluating safe harbour eligibility, and determining top-up tax obligations under the IIR, UTPR, or QDMTT.

• Over 40 jurisdictions have enacted Pillar Two legislation as of March 2026, with the 15% minimum ETR applied jurisdiction-by-jurisdiction
• The Income Inclusion Rule requires parent entities to include top-up tax for low-taxed constituent entity jurisdictions
• QDMTTs allow domestic application of the top-up tax before IIR or UTPR, adopted by India, UK, and most EU states
• Substance-based income exclusions carve out 5% of eligible payroll and 5% of tangible assets from the GloBE base

AI-Powered GloBE Calculation Engine

The computational complexity of GloBE compliance far exceeds what spreadsheet-based approaches can handle reliably. A typical in-scope MNE with operations in 30+ jurisdictions and 100+ constituent entities must perform jurisdiction-by-jurisdiction ETR calculations involving hundreds of data inputs and dozens of adjustment categories for each entity. Vidhaana's compliance dashboard automates the entire GloBE calculation workflow. The platform ingests financial data from each constituent entity's general ledger, trial balance, and tax provision workpapers, mapping account balances to GloBE income and covered tax categories. Automated adjustments handle the most complex GloBE income items: stock-based compensation elections (deduction-based versus grant-date fair value), excluded dividends and equity gains under the ownership threshold test, fines and penalties policy disallowed expenses, asymmetric foreign currency gains and losses, and prior period errors requiring restatement of previously filed GloBE returns. The covered tax calculation addresses current tax expense allocation to appropriate jurisdictions, deferred tax liability adjustments (including the recapture rule for DTLs not reversed within five years), uncertain tax positions under GloBE, and taxes paid by flow-through entities. Safe harbour evaluation modules automatically assess each jurisdiction against the Transitional CbCR Safe Harbour's three tests: de minimis test (revenue under EUR 10 million and income under EUR 1 million), simplified ETR test (simplified covered taxes divided by simplified income exceeding the transition rate), and routine profits test (income less than or equal to SBIE). For jurisdictions qualifying for safe harbour, the platform documents the basis and monitors ongoing eligibility. The AI generates GloBE Information Returns (GIR) in the standardized XML format specified by the OECD, ready for filing with the designated jurisdiction. Cross-checks validate calculation consistency, flag unusual results for review, and generate audit trails documenting every calculation step for tax authority examination.

DAC7, CARF, and Digital Platform Reporting

Beyond Pillar Two, the broader global tax transparency agenda introduces additional compliance obligations that AI platforms must address. The EU's DAC7 Directive (Directive 2021/514/EU), effective January 2023, requires digital platform operators to collect and report information about sellers generating income through their platforms to EU tax authorities. Reportable activities include rental of immovable property, personal services, sale of goods, and vehicle rental. Platforms must report seller identity information, financial account details, consideration paid, and the number of relevant activities, with information exchange between member states through the Common Communication Network. Non-compliance penalties vary by member state but can reach EUR 5,000 per unreported seller in some jurisdictions. The OECD's Crypto-Asset Reporting Framework (CARF), adopted in June 2023 and being implemented through domestic legislation across early-adopter jurisdictions, requires crypto-asset service providers to report transactions including exchanges, transfers, and retail payment transactions above specified thresholds. The EU implemented CARF through DAC8 (Directive 2023/2226), effective January 2026. India's tax information exchange framework under Section 285BA of the Income-Tax Act already requires reporting of specified financial transactions, and the government has indicated plans to incorporate CARF obligations into the existing framework. AI platforms automate the data collection, validation, and reporting required by these frameworks, identifying reportable transactions, collecting required seller and transaction information, validating data completeness and accuracy, and generating reports in the prescribed XML schemas for submission to relevant tax authorities.

• DAC7 requires digital platforms to report seller income data across EU member states, with penalties up to EUR 5,000 per unreported seller
• CARF reporting for crypto-asset transactions implemented through EU DAC8 effective January 2026
• India Section 285BA specified financial transaction reporting framework expanding to incorporate CARF obligations
• AI automates data collection, validation, and XML report generation across all digital platform and crypto reporting frameworks

U.S. Tax Interaction and Multi-Framework Coordination

The interaction between Pillar Two and U.S. domestic tax provisions creates one of the most complex areas of international tax compliance. The U.S. has not enacted Pillar Two legislation, but U.S.-parented MNEs are subject to GloBE Rules enacted by jurisdictions where their subsidiaries operate. The GILTI regime under IRC Section 951A imposes a minimum tax on certain foreign income, but its blended calculation methodology (aggregating all CFC income rather than calculating jurisdiction by jurisdiction) and 50% Section 250 deduction (creating a 10.5% effective rate, increasing to 13.125% from 2026 under the Tax Cuts and Jobs Act sunset provisions) differ significantly from GloBE methodology. The OECD's GILTI Co-Existence Guidance addresses whether GILTI qualifies as a Controlled Foreign Company (CFC) Tax Regime under the GloBE Rules, providing conditional safe harbour treatment. The BEAT under IRC Section 59A applies a minimum tax rate on modified taxable income calculated by adding back base erosion payments, creating additional interaction complexity with the UTPR. AI platforms model these interactions, calculating GloBE liability both with and without GILTI CFC Tax Regime treatment, evaluating BEAT exposure in the context of UTPR allocations, and optimizing group-level tax positions across the GloBE and U.S. frameworks simultaneously. For MNEs with both U.S. and non-U.S. ultimate parent entities, the platform models the full interaction including Foreign Tax Credit (FTC) implications under IRC Section 901 and 960 for top-up taxes paid in foreign jurisdictions. This multi-framework optimization capability represents one of the most valuable applications of AI in international tax compliance.
