For multinationals with a calendar year-end, the FY2024 Pillar Two filings are due on June 30, 2026. This means that the preparation work needs to be underway now.
The challenge most tax teams face at this stage isn’t only the calculations. It’s the step before the calculation: knowing which Pillar Two forms their organization needs to file, across which jurisdictions, and in what format. Before you can populate a GIR or a QDMTT return, you need a clear picture of your filing obligations based on your actual entity structure and GloBE status.
That’s harder to establish than it sounds. Filing requirements vary significantly by jurisdiction. Some countries require a GIR, a separate QDMTT return, an IIR form, and a registration notification. Others require only a self-assessment return. The transitional CbCR safe harbor may eliminate the need for full calculations in certain jurisdictions, but it may not eliminate the GIR filing obligation. Getting this mapping wrong early creates rework at exactly the wrong moment.
Introducing the Pillar Two Compliance Accelerator
To support multinationals with this momentous task, Orbitax is offering a free Pillar Two Compliance Accelerator, designed to give tax teams a filtered view of their Pillar Two filing obligations based on their own data.
The accelerator works best for a specific fact pattern. For US-headquartered multinationals, the 1120 XML is the recommended starting point as it contains entity structure, ownership, and tax data in a single file. For non-US multinationals using a CbCR XML, the workflow performs most reliably where there is one ETR group per jurisdiction and no flow-through entities in the ownership chain. In this fact pattern, the CbCR data maps cleanly to the safe harbor inputs, entity scoping runs automatically, and the workflow can determine filing obligations with minimal manual intervention. Where the fact pattern is more complex with multiple ETR groups within the same jurisdiction, flow-through entity ownership, or entity types and ownership data that are absent from the CbCR; additional manual input steps will be required, and the full GMT solution is likely the more appropriate path.
How does it work?
You upload your Form 1120 XML (US Multinationals) or CbCR XML (non-US Multinationals). The platform reads your entity structure, determines the GloBE status of every constituent entity, applies CbCR safe harbor logic where applicable, and filters out entities that are not in scope. What you get back is a complete list of every Pillar Two form your organization needs to file, drawn from Orbitax’s library of Pillar Two forms across the jurisdictions where filings are currently required.
From there, you have a clear path forward. You can purchase and populate individual forms directly from the platform, working through them manually at your own pace. Or, if you need end-to-end support across calculations, data collection, and transmission, you can move to the full Global Minimum Tax (GMT) solution for unlimited access to all Pillar Two forms alongside the GMT calculator, automated data collection workflows, and direct XML transmission to tax authorities.
A note on CbCR XML uploads
The CbCR XML works well for many fact patterns, but there are limitations worth understanding before you begin. The CbCR XML does not contain entity type or ownership data. When you upload a CbCR XML rather than a 1120 XML, the platform will extract what it can: total revenue, profit before tax, and jurisdiction-level data. An entity data template will need to be completed with the missing ownership and entity type fields manually for best results.
Why it matters for the June deadline
The June 2026 deadline applies to FY2024 GIR filings. For many organizations, this is their first year filing a GIR, and the complexity of that process is only fully visible once you start mapping your obligations against your entity structure. Teams that are still working from a rough sense of their filing footprint are carrying more risk than they realize.
Our Compliance Accelerator removes that uncertainty. It gives you a documented, data-driven output you can act on immediately, whether that means purchasing the specific forms you need, briefing your advisory team, or making the case internally for a more complete technology solution ahead of the FY2025 filing cycle.
The workflow is free to run with just a free Orbitax account to access it, which you can create in under two minutes.

What comes next
Once you have your filing list, you can move forward in two ways:
- If you’re looking to handle specific filings for this cycle, you can purchase individual forms directly. Each form can be populated manually within the platform, and the Filing Manager supports bilingual display, field-level validation, and activity tracking across your team.
- If you need a more complete solution for this year and beyond, the full GMT solution covers the entire Pillar Two compliance cycle from entity scoping and data collection through to calculations, GIR preparation, and XML transmission. We currently support machine-to-machine transmission for the UK and Germany, with Canada and Australia in progress; and more countries will be added as they support it. It also includes local country calculators for QDMTT, IIR, and UTPR across 190+ jurisdictions, and integrates directly with your existing ERP and data infrastructure through 90+ out-of-the-box connectors. All forms on the platform come bundled with our GMT solution with unlimited form generations.
