Hackers continue to successfully attack the IRS. The underfunded agency doesn't have the talent or capital to stop them. The IRS has an $11.2 billion budget for 2016, which after adjusting for inflation is less than its budget in 1995.
The IRS’s latest and perhaps most spectacular foray into disaster was an online feature called Get Transcript. The tool, which for the first time allowed taxpayers to download their records directly from IRS.gov, was supposed to be the happy ending to the decades-long struggle to bring the IRS’s J.F.K.-era legacy technology into the Internet age. But in February the bureau announced that hackers had used Get Transcript to steal the personal information of 724,000 people. The hack, it turned out, was six times as damaging as the IRS initially thought when it detected the breach and shut down the tool last May.
