Pillar 2 Calculations

Automated Workflows Powered by E.A.T.

Tax Rules and Compliance for over 190 Countries

Connections with 90+ ERP & Tax Authority Systems

The two pillars are estimated to levy a total of $275 billion in additional taxes annually on the ten thousand plus MNEs impacted by the rules.

Load Data

The data required for the global minimum tax calculation is organized into six Smart Data input templates. The GMT calculations are based on the data points from these six data input templates.

Data can be loaded through the export and reimport of Excel Data, upload of user defined source files using field mapping, EAT workflows for data collection, or Orbitax Connect- APIs for automated data push and pull with external systems.

Orbitax can consume data in any format. Once the data is in the platform it will be converted into a single proprietary data format that we call QNR and saved on the Orbitax Drive. This makes it possible to combine data points from any source.


The Orbitax GMT software has detailed QDMTT, STTR and GloBE (IIR and UTPR) calculations based on each local country’s implementation. The intelligent logic of the Executable Actions Tool manages the sequence and interaction of these local country calculators.

The flexible architecture of the platform allows you to easily update or compare scenarios with changes to the entity footprint or underlying data sets.

Reports & Forms

The Orbitax Global Minimum Tax Solution will support all local country filing requirements (GloBE Information Returns and other local filings) including e-filings where supported.

See a complete report view in Microsoft Power BI. This includes multiple configurable visuals for viewing and presenting results summaries, scenario comparisons, and year-over-year changes.

Share & File

The platform allows you to share or file with local tax authorities, connect to and transmit data to other software solutions, such as ONESOURCE Tax Provision, and provide reports and customized insights to others inside and outside your organization.

Next Gen Workflows with E.A.T.

A built-in workflow tool, the Orbitax Executable Actions Tool (E.A.T.), can automate tasks such as data collection, calculation, report generation, population of compliance forms, and final transmission to tax authorities.

E.A.T. provides total control of workflows customized according to different data needs, with visual review and tracking to easily make refinements as the workflow is deployed.
