The 2025 Data Review Report from Notice Ninja is a strategic asset for tax operations teams navigating a more complex, fast-moving compliance landscape. Built on verified activity from our platform and informed by broader federal and regulatory trends, it highlights how some teams manage tens of thousands of notices each year while others face comparable pressure from multi-entity structures, international jurisdictions, or lean internal staffing.
The report delivers actionable benchmarks, emerging risk indicators, and technology trends that enterprise tax teams can use to prepare for the year ahead.
As government agencies modernize, while others maintain legacy processes, notice volume continues to rise, organizations that rely on manual or fragmented frameworks will face growing exposure. The path forward requires better visibility, standardized workflows, and systems that can adapt as compliance requirements shift.
The IRS workforce decreased by 25 percent in the first half of 2025, but notice issuance held steady across federal, state, and local agencies. This created a widening gap between agency demands and taxpayer readiness. The IRS is continuing to move toward digital-first enforcement, and the BDO 2026 Tax Policy Outlook reinforces that policy shifts will persist into next year.
On the NOTICENINJA platform, compliance activity surged in response to this environment:
California generated the highest workflow volume by state, reflecting the operational complexity of managing tax notices across multiple jurisdictions. This state-level activity is increasingly becoming a national concern for large employers and tax departments.
Agencies are expected to move faster and with less tolerance for response delays in 2026. According to BDO, tax authority priorities include enforcement simplification, faster audit triggers, and increased reliance on digital correspondence. Meanwhile, TIGTA findings point to continued IRS resource constraints, which are accelerating the shift to automation and away from agent-supported engagement.
Organizations managing 5,000 to 25,000+ tax notices annually which is common among enterprise tax teams and Fortune 1000 companies and they are especially exposed if they lack standardized processes and automation. Our data shows that teams with outdated workflows or inconsistent ownership models experienced higher rates of escalation, aging notices, and missed resolution windows.
Global compliance continues to expand in both complexity and volume. NOTICENINJA has the ability to support users in over 170 countries and processed notices in more than 90 languages. This reinforces the need for systems that scale internationally with built-in localization and governance.
The 2025 Data Review Report identifies three areas where organizations using NOTICENINJA improved performance, reduced risk, and built resiliency:
Amanda Reineke, CEO and Co-founder of Notice Ninja, emphasizes the operational value of centralized systems:
“We are seeing a shift in mindset. Forward-thinking tax teams are investing in scalable systems that help them respond quickly, consistently, and with full visibility. It is not about volume alone. It is about managing risk with speed, confidence, and coordination.”
As enforcement becomes more automated and less forgiving, tax departments without scalable systems will fall behind. Audit timelines are tightening. Refunds are increasingly delayed due to notice backlogs. Multi-jurisdictional exposure continues to rise. The combination of these forces makes inaction more costly each quarter.
The data shows that organizations investing in automation and visibility are not just resolving notices faster. They are making compliance more predictable and reducing time spent on low-value tasks.
The 2025 Data Review Report details risk patterns across industry segments. Teams across key verticals face heightened exposure due to notice volume and operational fragmentation, including:
