Critical workers kept the Internal Revenue Service’s filing season on track this year, but a new federal watchdog report signals a sharp turn ahead. The Treasury Inspector General for Tax Administration warned that those same employees may not be in place in 2026, raising the risk of slower service and delayed enforcement when taxpayers need help most.
The report outlines the who and the when in stark terms. It points to essential staff who handled core duties during the latest tax season. It also flags a coming gap, citing 2026 as the point when many will no longer be on the job. The concern is clear: if the agency cannot replace or reassign these roles, service could slip just as rules and technology keep changing.
What the Watchdog Found
“Critical staff stayed on the job for this year’s tax season, but that won’t be the case in 2026,” the Treasury Inspector General for Tax Administration said in a new report.
The warning reflects a broader pattern. The IRS has relied on experienced workers to clear backlogs, process refunds, and answer questions. Many of these employees are eligible to retire or move to other roles. TIGTA’s message suggests that the buffer created by holdovers is temporary.
The timing matters. The agency faces complex filing seasons due to changing credits, new technology tools, and a stronger push against refund fraud. Losing trained staff at once can strain operations that depend on institutional knowledge.
Background: An Aging Workforce and High Demand
The IRS has faced staffing churn for years. Hiring surged recently, but training takes time. Veteran employees carry large caseloads, run specialized systems, and guide new hires. When they leave in clusters, performance can slip even if headcount appears steady.
Backlogs from earlier disruptions have largely improved, yet service is not fully restored. Call volumes stay high each spring. Digital services help, but many cases still need a skilled employee to review documents, correct errors, or flag fraud.
Risks for Taxpayers and the Economy
The near-term risk is longer wait times and slower refunds. Complex returns could face more reviews. That can pinch cash flow for households and small firms that depend on timely refunds or credits.
There is also an enforcement side. Fewer seasoned examiners can reduce audits of high-risk cases. That may weaken deterrence and lower revenue collection. New hires can fill the gap, but they need training and supervision that only experienced staff can provide.
IRS Efforts and Options
The agency has tried to speed hiring, improve training, and expand digital tools. Officials have emphasized customer service gains, such as shorter phone wait times in select call centers. They also point to new online features for tracking refunds and responding to notices.
Still, replacing deep expertise is hard. Specialized roles in enforcement, appeals, and information technology require long apprenticeships. TIGTA’s warning suggests that the calendar is tight for building that pipeline before 2026.
- Accelerated hiring in key job series.
- Retention incentives for high-skill roles.
- Expanded training and mentorship for new staff.
- Targeted outsourcing of non-core tasks, where allowed.
What Industry and Advocates Say
Tax professionals often welcome faster service but worry about uneven capacity. They report that complex issues still take weeks to resolve. Taxpayer advocates have called for clearer timelines, more transparency on processing status, and dedicated support for low-income filers.
Both groups agree on one point. A steady workforce is vital each filing season. The sudden loss of experienced staff can undo recent gains.
The Road to 2026
The next two filing seasons are a test. The IRS must keep service stable while building depth in its ranks. TIGTA’s report sets an urgent clock on that work.
Key measures to watch include hiring and attrition rates in critical jobs, phone and processing metrics, and how quickly new staff reach proficiency. Policy changes that add complexity to returns will also matter, since complexity amplifies staffing gaps.
The bottom line is straightforward. The agency held the line this year with veterans at the helm. By 2026, that safety net may be gone. The success of near-term hiring, training, and retention will determine whether taxpayers feel the difference.
