The Internal Revenue Service is replacing a key, two-decade-old customer service measurement widely criticized as misleading with new metrics designed to reflect modern taxpayer interactions.
This strategic pivot, announced on the eve of the tax filing season, signals a profound shift toward a digital-first service model under new leadership. The overhaul aims to transparently track performance across all service channels, moving beyond an outdated focus that captured only a fraction of caller experiences.
IRS Chief Executive Officer Frank Bisignano outlined the changes in an internal memo, stating the agency will retire its traditional “Customer Service Representative Level of Service” metric. This older measurement, which reported an 88% service level for fiscal 2024, only applied to calls on specific accounts management lines, representing just a quarter of the IRS’s total call volume.
In reality, the agency answered less than one-third of all calls received during the last filing season, a discrepancy long highlighted by the National Taxpayer Advocate as creating a misleading public picture.
The new enterprise metrics will instead track the average speed to answer calls, call abandonment rates, and total time taxpayers spend resolving issues. Bisignano emphasized this will provide a more accurate and holistic view of service quality as the agency accelerates its technology investments. “At the heart of this vision is a digital-first taxpayer experience, complemented by a strong human touch wherever it is needed,” he wrote, framing the change as critical for achieving the best filing season results in timeliness and accuracy.
This metric revision is part of a broader senior leadership shakeup at the IRS and Social Security Administration, both overseen by Bisignano. The move directly addresses advocacy and congressional concerns, following the Taxpayer Advocate’s mid-year report which labeled the old metric as deeply flawed.
By adopting metrics that align with contemporary customer service standards, the IRS seeks to bolster public trust and more effectively gauge its performance in solving taxpayer problems across phone, digital, and in-person channels.
