According to our (Global Info Research) latest study, the global Tax Appeal market size was valued at US$ 7111 million in 2025 and is forecast to a readjusted size of US$ 23443 million by 2032 with a CAGR of 18.5% during review period.
Tax appeal refer to the actions and professional services provided by taxpayers (individuals or enterprises) who, when they believe that a tax authority's decision to reject a tax assessment, supplementary tax payment, fine, or refund, or other tax administration decision, contains errors in fact-finding or application of law, raise objections and request corrections, reductions, or revocations through procedures such as administrative review, independent tax courts/arbitration, or judicial litigation.
Gross Profit Margin Level
Tax appeals are a typical "high-labor-density + high-professional-premium" service. The gross profit margin is primarily determined by the personnel level structure (the proportion of partners/senior managers), case complexity, and reusable toolchains (data analysis, document templates, evidence management).Generally, standardized audit response + administrative review (clear process, replicable delivery) has a gross profit margin of 30%–45%. Cross-border transfer pricing, major litigation, and disputes involving criminal liability/high risk have higher gross profit margins due to the investment of senior personnel and higher premiums, reaching 45%–60%. While adopting a "managed dispute management/batch small-amount case factory" model results in a lower ASP per case, a stable gross profit margin of 25%–40% can be maintained through process and technology, shifting the profit focus from "single-case bursts" to "scaled delivery + repeat purchase stickiness."
Industry Drivers
The underlying driving force behind the growth of the tax appeals market stems from a triple effect of "more complex rules + stronger enforcement + more transparent data." On the one hand, new rules such as the Pillar Two tax, transfer pricing, and digital services tax continue to increase cross-border uncertainty, expanding the points of contention from "single tax type" to "group tax governance and profit distribution systems," directly pushing companies to invest more in dispute management and appeal capabilities. On the other hand, tax authorities in many countries are accelerating the adoption of data analytics and AI tools, leading to stricter audits of large partnerships, high-net-worth individuals, and multinational corporations. Companies need to establish evidence and narrative frameworks throughout the entire audit-reconsideration-litigation chain. Simultaneously, the emergence of ultra-large-scale cross-border disputes (typically transfer pricing-related cases) and their expanding impact have made boards of directors and audit committees more inclined to purchase "provable, auditable, and closed-loop" dispute resolution services, thereby driving the continued expansion of leading comprehensive professional service institutions and law firms with strong litigation capabilities in the high-end market.
