Tax Systems launches AI Assistant for cross-border tax

Tax Systems has launched an AI Assistant for cross-border tax research and analysis, developed by Loctax, a Tax Systems business.

The product combines company-specific data with tax content from the International Bureau of Fiscal Documentation, or IBFD. It is aimed at multinational organisations managing tax questions across more than 220 jurisdictions. Covering multiple tax domains, the assistant is designed to return answers tailored to a company's structure rather than generic responses.

Users can ask questions, draft and review tax memos, analyse contracts and documents, test structuring scenarios, and validate existing advice within a single platform. The system is intended to reduce the manual research that tax teams must conduct before responding to internal business requests.

According to company figures, the software can free up five hours per user each week and cut memo preparation time by up to 80%. Those claims reflect a broader push by tax software providers to demonstrate measurable savings as artificial intelligence tools move from pilot projects into everyday work.

IBFD link

Tax Systems describes the product as the first to integrate IBFD content across all tax domains with an organisation's internal data. IBFD is a long-established non-profit tax research body with a large network of researchers and authors, and its material is widely used by tax professionals handling international issues.

The product is aimed at in-house tax departments and advisers who need to assess tax rules across several countries while tracking business-specific facts. Cross-border tax work often requires teams to compare local rules, review transaction documents, and check whether previous advice still holds as facts or regulations change.

Stevi Frooninckx, Chief Executive Officer and Founder of Loctax, said tax teams often lose time to research and validation before they can advise the wider business.

"Tax teams have traditionally been constrained by the time required to carry out detailed research and validate their findings before they can support the business," Frooninckx said. "The AI Assistant changes this dynamic by enabling teams to move more quickly from analysis to action. Rather than just supporting research, it serves as a gateway for conducting cross-border tax analysis much more efficiently, acting as a tax technical sparring partner for each member of the team."

Security controls

The assistant includes role-based access controls and keeps customer data separate from AI model training. That issue has become central to AI adoption in finance, legal, and tax functions, where documents often contain commercially sensitive material and personal data.

Russell Gammon, Chief Innovation Officer at Tax Systems, said the inclusion of company data was central to the product's design.

"The combination of IBFD's verified international tax content and an organisation's unique data is what makes this tool so powerful," Gammon said. "Other tools can answer a tax question, but the AI assistant understands each business and its specific circumstances, which means the insights it delivers are directly relevant and immediately usable. As such, it represents a significant step forward for in-house tax teams and advisors alike."

The launch reflects a broader shift in the tax technology market, with software groups moving beyond compliance workflows and document management into research, review, and decision support. Multinational tax teams are under pressure to respond more quickly to transactions, new market entries, and internal restructuring while managing evolving rules across multiple territories.

Tax Systems has expanded in that direction since acquiring Loctax, which specialises in software for global tax operations, including workflow management, collaboration, and audit trails for in-house finance and tax teams. Combining that operational data with external tax content enables the group to embed AI into existing tax processes rather than offer a standalone research tool.

The AI Assistant is available immediately to organisations globally.

"This launch reinforces our position as an AI-first technology company," said Bruce Martin, Chief Executive Officer of Tax Systems. "By combining company-specific data with trusted global tax content, the AI Assistant enables teams to generate more relevant insights, move faster, and make better-informed decisions. This approach underpins our continued focus on delivering intelligent solutions that address the real challenges faced by tax professionals and make a tangible difference for our customers."
