AI & tax intelligence set to transform business compliance by 2026

Global businesses are set to face a year defined by heightened digital precision, new tax challenges, and the expanding influence of artificial intelligence (AI) in governance and compliance by 2026, according to senior executives at Avalara. Predictions focus on fundamental changes in finance, trade, retail, e-invoicing, and the hospitality sector driven by new regulations, technology and increased scrutiny.

Finance strategy

Finance chiefs are expected to transition from traditional roles to become strategic orchestrators of digital value, with a growing reliance on unifying financial, tax, and operational data. Data-led scenario modelling, driven by AI and automation, is anticipated to replace much of the traditional compliance burden, allowing finance teams to operate more as analytics consultancies.

"CFOs are becoming data strategists. In 2026, the finance function's ability to unify financial, tax, and operational data will define enterprise agility. Finance professionals who view tax beyond a cost to a strategic insight will lead the next wave of intelligent growth for their businesses," said Ross Tennenbaum, President, Avalara.

Tax complexity is anticipated to become a major enterprise risk, with growing pressures from governments on real-time digital reporting and global minimum tax mandates. Budgets will increasingly cover audit defence and ensuring data integrity, moving away from compliance data silos towards using tax intelligence in wider business planning.

AI in compliance

AI adoption will increase in tax and compliance functions, turning automation from a tool for experimentation to a core element of governance. Business leaders predict that continuous, real-time compliance will soon replace traditional periodic reporting as regulatory demands shift towards instant transaction transparency.

"AI will reshape how businesses manage compliance. The biggest challenge in 2026 is governing automation. As AI takes on more tax and compliance decisions, accountability is critically essential," said Danny Fields, Chief Technology and Customer Operations Officer, Avalara.

Metrics such as resilience and reliability are moving to the centre of compliance, with continuity during disruption now seen as integral to maintaining regulatory trust. Fields expects that AI's real impact will be judged by its orchestration and integration with human oversight, with measurable levels of trust in governed systems.

Tax and regulation

Following significant U.S. tax changes, the business environment is predicted to experience fewer major tax overhauls in 2026. However, growing compliance complexity is expected as states respond differently to reduced federal funding and as digital sectors come under greater audit scrutiny.

"The permanent extension of 100% depreciation will influence capital investment strategies, while expiring provisions in the 2025 tax package could trigger new legislative debates," said Scott Peterson, VP of Government Relations, Avalara.

States such as Colourado are already adjusting their tax codes in response to federal moves, with jurisdictions facing decisions on alignment or divergence. Digital industries, particularly software, SaaS, and lodging marketplaces, are anticipated to face wider sales tax regimes and increased audit risk.

Global trade shifts

Trade volatility is forecast to decrease slightly, but increased complexity remains as global supply chains diversify beyond the United States. Accurate classification of goods and digital traceability are now critical to minimising costs and maximising competitiveness.

"2026 will not bring calm, but it will bring clarity. The winners will be those who can anticipate change and adjust their supply chains accordingly," said Craig Reed, General Manager of Cross Border, Avalara.

Businesses that view compliance as a discipline focused on data accuracy are likely to dominate, especially as errors in documentation can have significant financial consequences.

"Global trade in 2026 will reward companies that can anticipate change. The U.K. is reemerging as a dynamic trade hub, and those that align supply chain agility with compliance precision will turn complexity into opportunity," said Carlos Mercuriali, Senior VP and General Manager of International Business Operations, Avalara.

Digital commerce

Retailers and marketplaces are anticipated to see AI-driven transformation across sales and compliance operations. Automation is expected to scale, but so are associated risks, making strong governance and auditability a strategic priority.

"In digital commerce, AI will reshape every aspect of the retail and marketplace ecosystem," said George Trantas, VP of Accelerator Sales, Avalara.

Tailored AI recommendations will drive customer engagement, with tax intelligence underpinning growth and helping to ensure transactional accuracy and audit readiness.

E-invoicing momentum

With more than 60 countries moving towards mandatory e-invoicing by 2030, digital compliance will become not just an obligation but an operational advantage. Businesses will shift from reactive reporting to proactive use of standardised, real-time data across jurisdictions.

"By 2026, e-invoicing will become a strategic business advantage, moving beyond a government mandate," said Alex Baulf, VP of E-Invoicing and Live Reporting, Avalara.

Adopting digital tax mandates will facilitate more efficient and borderless trade, according to Baulf.

Hospitality trends

In the accommodation sector, the focus will shift to managing non-uniform state regulation and responding to changing consumer habits as remote work trends shift. Increased enforcement, powered by AI, will help governments quickly identify non-compliant short-term rentals.

"Operators must navigate a patchwork of changing lodging and special-district taxes, particularly in California, Hawaii, Illinois, Connecticut, and Colourado," said Nicole Rogers, General Manager of Lodging, Avalara.

"Jurisdictions are using AI-powered tools to identify noncompliant STRs in real time. Enforcement is becoming faster, smarter, and more consistent than ever before," said Pam Knudsen, Senior Director of Compliance Services, Avalara.
