The Internal Revenue Service (IRS) entered the 2026 tax season facing significant internal disruption driven by workforce reductions, policy shifts, and operational constraints. Despite these challenges, recent findings from the Government Accountability Office (GAO) reveal a surprising level of resilience in IRS performance.
For tax professionals, CPA firms, and outsourcing providers, this evolving landscape highlights both risks and opportunities—particularly in client advisory, compliance efficiency, and service delivery expectations.
Key Developments from the 2026 Tax Season
1. Significant Workforce Reduction
- Approximately 17,047 employees (around 17% of the workforce) exited the IRS in 2025 through early retirement and deferred resignation programs.
- This included over 5,000 employees directly involved in filing season operations, such as return processing and customer service.
- Leadership instability also persisted, with multiple commissioner changes within a year.
These changes have raised concerns about long-term operational stability and institutional knowledge loss.
2. Tax Season Performance Remains Stable (For Now)
Despite staffing challenges:
- IRS customer service performance remained comparable to previous years.
- Around 9 million taxpayer calls were handled annually (2024–2025).
- Paper return processing times improved slightly compared to 2024, although the agency missed its 13-day processing goal.
This stability was largely possible because staff departures were delayed until after the filing season, temporarily cushioning the impact.
3. Persistent Backlogs and Service Gaps
One of the biggest concerns highlighted:
- IRS correspondence backlog remains above pre-pandemic levels.
- There is no clear plan to reduce this backlog, according to oversight authorities.
This creates risks of:
- Delayed taxpayer responses
- Slower issue resolution
- Reduced service quality in future tax seasons
4. Lack of Strategic Workforce Planning
The Government Accountability Office (GAO) raised critical concerns:
- The IRS paused its previous workforce strategy and is developing a new one aligned with administrative priorities.
- Without a structured plan, the agency may struggle to:
- Identify staffing needs
- Allocate resources effectively
- Maintain service levels
The GAO recommended:
- A formal backlog reduction plan
- A revised workforce strategy
- A dedicated implementation team for reforms
Implications for Taxpayers and Accounting Firms
What This Means in Practice
- Delays may increase for complex filings and correspondence-heavy cases
- Phone support may remain stable, but not necessarily improve
- Paper filings will continue to lag behind e-filings
- Future tax seasons could see service degradation if staffing gaps persist
Opportunities for Accounting Firms
This environment creates a strong case for professional advisory and outsourcing services:
- Firms can bridge IRS communication gaps for clients
- Increased demand for proactive tax planning and compliance support
- Opportunity to position as a reliable intermediary between clients and IRS systems
- Growth in outsourced tax preparation and support services
Conclusion
The IRS has demonstrated resilience by maintaining service levels during the 2025 and early 2026 tax seasons despite substantial workforce reductions. However, this stability may be temporary.
Without a clear workforce strategy and backlog reduction plan, the agency faces mounting risks that could impact taxpayer experience and compliance efficiency in the years ahead.
For accounting professionals, this shift reinforces a critical reality: clients will increasingly rely on expert guidance to navigate inefficiencies and uncertainties within the tax system.
