Global tech provider Tax Systems has introduced a new software solution, Pillar2, aimed at helping businesses save time and minimize errors in meeting the OECD’s pillar two tax regulations. The software, which targets multinational corporations operating in various jurisdictions, was officially launched today, January 15.

Bruce Martin, CEO of Tax Systems, highlighted the challenges tax professionals face in navigating these complex rules. "Pillar two compliance has added further complexity to tax professionals’ already heavy workloads, but our solution can take some of the burden by calculating any top-up tax due accurately and efficiently,” he said.
Martin emphasized the advantages of the new platform, adding, “Armed with the ability to manage their entire tax control framework from a single, fully connected platform, organisations can significantly reduce operational complexity while ensuring accuracy in every step of the compliance process.”
The Pillar2 software integrates with TaxSuite, Tax Systems’ modular platform designed for international tax compliance. This integration allows businesses to upload their data once and re-use it as a single source for tax compliance purposes, streamlining operations and reducing redundancy.
One of Pillar2’s key features is a jurisdiction implementation tracker that displays where specific pillar two rules—such as the qualified domestic minimum top-up tax, income inclusion rule, and undertaxed payments rule—are currently in force worldwide. The tracker will be updated regularly by Tax Systems, helping organizations stay informed about regulatory changes without the need for constant monitoring.
Russell Gammon, chief solutions officer at Tax Systems, explained that the launch represents only the first stage of the software’s development. “The second piece of the puzzle that will be coming is the filing requirements,” he said.
Gammon pointed out that the OECD has yet to release its final XML schema, and individual countries have not yet detailed their filing instructions. He stated, “This current software is part one, which concerns how to calculate the numbers, which people are doing now and have been doing for the last year or two.”
Gammon projected that in 2025 and 2026, when filing obligations and tax payments begin, the Pillar2 product will be ready to support these processes. “Let’s say the OECD publish their scheme in June, then [later] we’ll roll the filing capability out once we know exactly what that looks like,” he explained.
He further noted that accommodating more than 100 local filing requirements would be a significant and complex task. However, he reassured users that the software is built to handle these needs. “We’ve built the software in such a way that we’re doing all of the core calculations you would need to populate those filings,” Gammon said.
The Pillar2 software, available from today, also features an audit trail that logs user actions and data changes, ensuring transparency and accountability. Real-time tax insights are another highlight, with generative AI capabilities providing data-driven answers to queries related to pillar two calculations.
The platform includes role-based access control, allowing organizations to restrict access to sensitive tax data to authorized personnel. It also offers flexible hosting options, enabling businesses to choose data hosting in either the UK or the European Economic Area based on their preferences.
