Pillar Two compliance should not depend on disconnected spreadsheets
Pillar Two brings together large volumes of financial, tax and entity-level data from across the group. That data must then be validated, adjusted, calculated and reported in line with OECD rules and evolving local requirements.
Alphatax brings your Pillar Two process into one controlled SaaS platform. It gives your tax team a structured way to manage data, automate calculations, collaborate with stakeholders, review outcomes and prepare reporting outputs across multiple jurisdictions.
When this process is managed through spreadsheets, email and separate data sources, tax teams can face:
- Inconsistent or incomplete data
- Limited visibility across entities and jurisdictions
- Complex spreadsheet calculations
- Version-control issues
- Repeated manual data handling
- Unclear ownership and review processes
- Weak audit trails
- Difficulty adapting to changing requirements
Designed for in-house tax teams managing Pillar Two across multiple entities, currencies and jurisdictions.

Three benefits of the Alphatax Pillar Two solution
Bring structure and control to Pillar Two compliance
Armacell needed a scalable way to manage approximately 20 local filing requirements alongside its central GloBE Information Return.
With Alphatax Pillar Two, the team created a more structured process, reduced the risk associated with Excel-based working and established a single source of data across its Pillar Two requirements.

Frequently asked questions about Pillar Two software
What is a Pillar Two solution?
A Pillar Two solution is software designed to help multinational groups collect the required data, perform GloBE calculations, calculate potential top-up tax and prepare the reporting required under OECD Pillar Two and relevant local legislation.
A dedicated solution provides greater automation, governance and auditability than a process built primarily around spreadsheets.
Which organisations are affected by Pillar Two?
Pillar Two generally applies to multinational enterprise groups with consolidated annual revenue of €750 million or more, subject to the detailed scope rules and legislation adopted in each jurisdiction.
Groups operating across multiple jurisdictions should assess where Pillar Two rules have been introduced and what calculation, registration, reporting and filing obligations apply.
What calculations does Alphatax Pillar Two support?
Alphatax supports the core calculations required under the OECD Pillar Two framework, including jurisdictional effective tax rate and top-up tax calculations for QDMTT, IIR and UTPR.
The software also supports relevant adjustments, elections, exclusions and safe-harbour assessments as part of a controlled calculation process.
Does Alphatax support the GloBE Information Return?
Yes. Alphatax supports the preparation of the GloBE Information Return using the same controlled data used for your Pillar Two calculations.
This helps improve consistency between calculations, group reporting and relevant local filing requirements.
Does the software support local QDMTT reporting?
Yes. Alphatax supports QDMTT compliance and reporting workflows across supported jurisdictions.
Where direct filing is available, the platform can support direct submission. Where it is not available, Alphatax provides practical alternative support, including populated filing outputs and the ability to capture additional local data requirements.
Can Alphatax manage multiple entities and jurisdictions?
Yes. Alphatax Pillar Two is designed for large multinational groups operating across multiple entities and tax jurisdictions.
Central dashboards, jurisdictional packs, workflow tools and role-based permissions give the group tax team visibility while allowing local teams and advisers to contribute where required.
Can Pillar Two compliance be managed in Excel?
Spreadsheets can support initial assessments and data analysis, but they become increasingly difficult to control as the number of entities, jurisdictions, adjustments and reporting requirements grows.
Manual spreadsheet processes can also create challenges around calculation consistency, version control, data lineage, review and auditability. Alphatax provides a more structured and repeatable alternative.
Can external advisers use the platform?
Yes. Role-based access allows internal tax teams, finance stakeholders and external advisers to work within the same platform while maintaining appropriate access controls.
Alphatax can support insourced, outsourced and co-sourced Pillar Two operating models.
Does Alphatax integrate with other tax systems?
Alphatax Pillar Two integrates with Alphatax Tax Provisioning and CbC Reporting, helping organisations reuse data and create a more consistent source of tax compliance information.
How does Alphatax support audit readiness?
Alphatax maintains calculation logic, data lineage, version history and records of user activity within the platform.
This creates a clearer evidence trail for internal governance, external assurance processes and potential tax authority enquiries.
Is Alphatax authorised for UK Pillar Two submissions?
Yes. Alphatax is included on HMRC’s list of authorised commercial software suppliers for UK Pillar Two submissions.
It supports UK Tax Returns, Overseas Return Notifications and GloBE Information Returns.
Can we see the software before making a decision?
Yes. Book a personalised demonstration and we will show you how Alphatax supports the Pillar Two process, from data collection and calculations through to review, reporting and filing workflows.
