A new report to Congress may explain why so many taxpayers this season are frustrated with the Internal Revenue Service.
The study by the National Taxpayer Advocate found the agency desperately needs more money to do its job.
The agency's budget has been cut by about 8 percent since 2010 and much of that funding paid for employee training.
About 8,000 fewer full-time workers are on staff and those cuts are turning into frustration for taxpayers.
In 2013, only 61percent of taxpayer calls were answered, which is down from 87 percent a decade ago.
Those who didn't get through waited an average of 17 minutes and more than half of all email and letters received no response.
Agents are also taking nearly a year on average to respond to identity theft investigations.
The IRS recently announced it won't prepare returns at all for personal assistance, citing cutbacks.
