WASHINGTON (AP) – The IRS’ overloaded phone system hung up on more than 8 million taxpayers this filing season as the agency cut millions of dollars from taxpayer services to help pay to enforce President Barack Obama’s health law.

For those who weren’t disconnected, only 40 percent actually got through to a person. And many of those people had to wait on hold for more than 30 minutes, IRS Commissioner John Koskinen said Wednesday.

The number of disconnected callers spiked just as taxpayers were being hit with new requirements under the health law. Last year, the phone system dropped 360,000 calls, Koskinen said.

For the first time, taxpayers had to report whether they had health insurance last year on their tax returns. Those who received government subsidies had to respond whether they received the correct amount. People without insurance faced fines, collected by the IRS, if they did not qualify for an exemption.
