IRS Customer Service Capacity Rises, Gaps Remain
Recent government data show improvements in IRS customer service capacity during the 2024 filing season, particularly on the agency’s central phone helpline. Oversight reports and budget documents, however, indicate that service levels varied by phone line and may face pressure in future years without sustained funding.
The Internal Revenue Service reported handling a large volume of taxpayer contacts during fiscal year 2024, supported by expanded staffing and digital tools. According to the Internal Revenue Service Data Book, 2024, customer service representatives answered approximately 20 million live phone calls between Oct. 1, 2023, and Sept. 30, 2024.
In addition to phone assistance, the IRS recorded more than 2 million contacts at its nationwide Taxpayer Assistance Centers. These in-person visits increased from the prior fiscal year, reflecting continued demand for face-to-face help with tax filing, account issues, and payment questions. The Data Book attributes the higher contact volume to a combination of seasonal filing demand and additional staffing resources.
During the 2024 filing season, the U.S. Department of the Treasury reported improved performance on the IRS’s central taxpayer helpline. Treasury said the agency achieved an 88 percent service level, meaning the majority of callers seeking live assistance reached a representative.
Treasury also reported average wait times of about three minutes on the central helpline during filing season. The agency noted that expanded call-back options were used to reduce time spent on hold, particularly during peak calling hours. These filing-season metrics were cited as evidence of progress in improving IRS phone service compared with earlier years marked by long delays and unanswered calls.
While Treasury highlighted strong filing-season results, an audit by the Treasury Inspector General for Tax Administration (TIGTA) cautioned that publicly reported metrics provide only a partial picture of IRS phone performance. In an August 2025 report, TIGTA found that the 88 percent service level figure applied only to 33 Accounts Management phone lines during the filing season.
According to TIGTA, IRS data showed that other staffed phone lines experienced significantly longer wait times. Average waits for these lines ranged from approximately 17 to 19 minutes during the 2024 filing season. The audit also found that service levels fluctuated by month, with better performance during peak filing periods and lower performance at other times of the fiscal year.
TIGTA concluded that commonly cited filing-season statistics may not fully reflect the experience of taxpayers who contact specialized or non-Accounts Management lines for assistance.
Treasury budget planning documents have emphasized that recent gains in IRS customer service capacity depend on sustained funding. In the IRS FY 2025 Congressional Budget Justification, Treasury warned that telephone service levels could decline sharply in fiscal year 2026 if taxpayer services funding is reduced or spending flexibility is limited.
The budget justification links staffing levels, technology investments, and training directly to the agency’s ability to maintain phone and in-person service. Treasury noted that without additional resources, the IRS may struggle to keep wait times low and service levels high outside of peak filing seasons.
For taxpayers, the reports suggest that reaching the IRS's central helpline during filing season has become easier than in recent years, according to official government data. However, oversight findings indicate that experiences can vary depending on which IRS phone line a taxpayer calls and when the call is made.
Looking ahead, Treasury and TIGTA reports signal that current service improvements may be difficult to sustain without continued funding. Taxpayers seeking assistance outside the filing season or through specialized phone lines may continue to encounter longer wait times, particularly if staffing levels decline in future fiscal years.
