IRS Overtime Costs Surge Amid Workforce Exodus and Operational Crisis
By [Your Name/Journalistic Staff]
The Internal Revenue Service (IRS) is grappling with a profound operational paradox: as its total headcount shrinks to historic lows, the agency’s reliance on overtime has ballooned, placing significant strain on both the federal budget and the remaining personnel tasked with managing the nation’s tax system. According to a May 15, 2026, report by the Treasury Inspector General for Tax Administration (TIGTA), the IRS saw a 12% increase in overtime hours throughout 2025, even as it navigated a massive reduction in its permanent workforce and a crippling 43-day government shutdown.
The findings paint a picture of an agency stretched to its breaking point, struggling to process millions of returns while suffering from a loss of institutional knowledge and a fragmented oversight structure.
The Fiscal Impact of a Shrinking Workforce
For the first nine months of 2025, the cost of overtime at the IRS surged to $225 million, a $27 million increase over the $198 million recorded during the same period in 2024. This expenditure occurred against the backdrop of a 14% drop in regular working hours across the agency, driven by a wave of departures.
In 2025, the IRS implemented several resignation and retirement programs intended to reshape its workforce. However, these programs resulted in a staggering 25% reduction in total staff. The transition period for these departures was marked by an explosion in administrative leave, which jumped from 569 hours to more than 1.9 million hours, as employees utilized leave time prior to their official separation dates.
TIGTA’s report concludes that the increased overtime costs were a functional necessity. "We believe that additional overtime costs were needed since the IRS had to balance increasing workforce demands with the impact of Service-wide workforce reductions," the auditors noted. The agency essentially traded its permanent, full-time capacity for temporary, high-cost overtime labor to keep core services from collapsing entirely.
Taxpayer Services: The Front Line of the Crisis
The burden of this operational instability has fallen disproportionately on the Taxpayer Services division. Responsible for 87% of all overtime hours logged in 2025, this division is the primary point of contact for the American public.
Contact representatives and tax examiners alone accounted for 4.3 million overtime hours—or 82% of the agency’s total. This group is responsible for the most critical functions of the IRS: answering taxpayer phone calls, processing returns, managing accounts, calculating penalties and interest, and performing collections.
The division’s capacity was gutted by the resignation programs, with the number of contact representatives reduced by 23% (roughly 6,000 positions) and tax examiners by 27% (roughly 4,000 positions). With fewer hands on deck to handle the same, if not greater, volume of taxpayer inquiries, the agency leaned heavily on the remaining staff to work extended hours. This creates a vicious cycle: as burnout increases among the remaining staff, the agency’s ability to retain talent diminishes, potentially leading to further workforce shortages.
Chronology of an Operational Stumble
The timeline of the 2025 fiscal year reveals a series of cascading events that hamstrung the agency:
- Early 2025: The IRS rolls out aggressive resignation and retirement programs to restructure its workforce. The unintended consequence is a rapid 25% decline in overall staff levels.
- January–September 2025: The agency begins a heavy reliance on overtime to mitigate the loss of personnel, resulting in a $225 million overtime bill.
- Late 2025 (43-Day Shutdown): A federal government shutdown lasts for 43 days, ending in November. This cessation of normal operations halted processing pipelines, causing a backlog of tax documents to swell.
- December 2025: Key tax processing inventories—the backlog of returns and correspondence waiting to be addressed—jump by 33%, from 1.5 million to 2 million cases.
- May 2026: TIGTA releases its audit, highlighting the lack of centralized oversight and identifying "questionable" overtime claims.
Questionable Claims and Oversight Deficiencies
Perhaps the most troubling aspect of the TIGTA report is the discovery of significant gaps in overtime management. Auditors identified 476 questionable overtime claims submitted by approximately 300 employees. These claims were flagged because they involved individuals logging more than six hours of overtime on top of a standard shift, resulting in excess of 12 "workable hours" in a single day.
The national agreement between the IRS and the National Treasury Employees Union (NTEU) generally prohibits bargaining unit employees from working more than 12 hours in a 24-hour period. Despite this, TIGTA found that 14 employees reported working 20 or more hours in a single day, with 71% of these instances occurring within the Taxpayer Services division.
The report highlights a systemic lack of internal control. The IRS currently lacks a centralized mechanism to track or approve overtime procedures. Instead, authority is decentralized, with individual business units setting their own documentation and approval processes. While IRS-wide policy requires that all overtime be officially ordered or approved in writing, the audit suggests that this policy is inconsistently enforced. Furthermore, the agency has no hard cap on the number of hours an employee can work in a given pay period, a policy gap that may be facilitating both legitimate burnout and potential abuse of the system.
Implications for the Future of Tax Administration
The implications of these findings are far-reaching. The backlog of 2 million tax cases represents a significant hurdle for the upcoming filing seasons. When the IRS cannot process returns or respond to correspondence in a timely manner, taxpayers face delays in refunds, erroneous penalty notices, and an overall loss of confidence in the tax system.
Furthermore, the agency’s reliance on overtime as a "fix" for structural workforce reductions is financially unsustainable. The TIGTA report was issued for informational purposes, meaning it did not provide specific recommendations for reform at this time. However, the agency has signaled that it plans to conduct a more rigorous assessment of premium pay and mandatory overtime controls during the 2026 filing season.
For the employees themselves, the environment is increasingly hazardous. Working 20-hour days—even in the context of a staffing crisis—raises serious questions about fatigue management, accuracy in tax processing, and the long-term mental health of the workforce. The referral of the 300 employees with questionable claims to the agency for further review suggests that the IRS is finally moving to address the lack of accountability in its payroll practices.
Moving Forward: The Need for Reform
The current situation at the IRS serves as a cautionary tale for federal agency management. While the goal of the 2025 workforce reductions may have been to improve efficiency or modernize the agency’s structure, the execution appears to have prioritized short-term headcount reduction over operational continuity.
As the agency looks toward the 2027 fiscal year, it faces a trifecta of challenges: rebuilding its workforce, clearing a massive backlog of tax inventories, and implementing stricter oversight of its payroll and overtime expenditures. Without a centralized, rigorous system to track hours worked and a sustainable approach to staffing, the IRS risks repeating the patterns of 2025, where high costs and employee burnout were the primary products of a system in distress.
The TIGTA audit serves as a sobering reminder that administrative efficiency cannot be achieved by simply asking fewer people to work longer hours. Until the IRS can reconcile its staffing levels with the actual volume of its mission-critical work, the specter of backlogs, service delays, and questionable overtime expenditures will likely continue to haunt the agency.
