Here's the lowdown
The IRS is studying how taxpayer services affect revenue, but the GAO says that work does not fully measure satisfaction, burden reduction and other benefits.
The GAO found limited staff, funding, data and long-term methods make service returns difficult to measure.
Research from other countries found positive links between taxpayer service and outcomes such as lower compliance costs for businesses.
The IRS does not have the full scorecard
The IRS spends money on websites, phone assistance, correspondence and in-person help. A new Government Accountability Office report says the agency still cannot fully show what taxpayers get from those investments.
The IRS is researching how service affects tax revenue. That matters, but revenue is only one result.
The agency is not currently planning to measure some other benefits in the same project, including taxpayer satisfaction and the burden people face when trying to comply.
Without those measures, budget decisions can favor activities that are easy to count while missing services that prevent mistakes, reduce repeat contacts or help people file correctly the first time.
Good service can support compliance
Taxpayer service is often treated as separate from enforcement. The GAO's review shows the line is not that clean.
Clear answers, usable online tools and faster issue resolution can make compliance easier. Confusing instructions and long delays can increase professional fees, taxpayer frustration and avoidable errors.
A 2013 IRS study found that poor satisfaction with services may contribute to noncompliance. The GAO also identified 12 studies involving tax agencies in other countries. All found some positive link between taxpayer service and taxpayer benefits.
Studies in Belgium and Germany connected more customer-focused service with lower compliance costs for business taxpayers.
Those findings do not prove every service program pays for itself. They do show that revenue collected is too narrow a measure.
The data problem has lasted for years
IRS reports in 2007 and 2008 called for more analysis of the compliance and revenue benefits tied to service spending.
The GAO says the IRS did not provide documented results from those earlier calls, though it found five IRS studies that examined service effects on compliance or satisfaction.
The agency began a new research effort after requesting a broader review in 2024. Officials said skilled staff, funding, data and long-term measurement methods remain difficult to secure.
Budget and staffing reductions make the work harder. Much of the extra funding provided by the Inflation Reduction Act has since been cut back.
That creates a loop. The IRS needs better evidence to defend service investments, but gathering the evidence itself requires people and money.
What a better measurement system would track
A useful service scorecard should include more than average wait time.
It should measure whether the taxpayer's issue was resolved, whether the same person had to contact the agency again, how much time and money compliance required and whether the service changed future filing behavior.
It should also separate simple contacts from complex cases. A two-minute balance question and a months-long identity-theft problem should not carry the same weight.
For online tools, the IRS should track successful task completion, not only page visits. For phone and in-person service, it should track first-contact resolution and downstream corrections.
Why accounting firms should care
Poor taxpayer service does not stay inside the IRS. It becomes work for accountants.
Firms spend time calling the agency, tracing correspondence, explaining delays and fixing problems that better guidance or faster resolution might have prevented.
That cost is paid by clients and practitioners even when it never appears in the IRS budget.
The GAO report makes the core problem plain: the agency cannot manage taxpayer service well if it cannot see the full return from that service.
Better measurement will not solve staffing or technology problems by itself. It will make it harder to cut a useful service simply because its benefits were never counted.
