According to a new report released Wednesday by House Republicans, the IRS deliberately cut its customer service this year and made the tax season more painful than it had to be for millions of taxpayers.

The report has accused the agency of wasting money on pet projects while hanging up on millions of callers.

On average, the wait times witnessed by callers spiked to 34.4 minutes before callers got through. Less than half of all callers got the opportunity in the first place and most calls were rejected by an overloaded system.

According to the House Ways and Means GOP staff , the IRS cut its funding for customer service and continued to spend money in areas which questionable by GOP lawmakers.

Rep. Peter J. Roskam, Illinois Republican and chairman of the Ways and Means oversight committee said that the fiscal year 2014 bonus money could have been used to answer 7.2 million additional phone calls.

However, John Koskinen IRS Commissioner stood up at the charges and said that he's been forced to make the cuts as Congress reduced his agency's budget even as the number of filings gone up.

According to him, the agency is also taking on ever more duties, such as policing Obamacare's individual mandate. The IRS has spent $1.2 billion on implementing Obamacare over the last four years, which was required by law.

He said, "We've had to make choices across the board. We've cut enforcement services, we cut taxpayer services, and we cut information technology".

According to him, these are the three discretionary areas where he can reduce spending. Therefore, he made cuts in all of them.

He mentioned that they've been cutting personnel as well, including hiring fewer temporary employees during tax crunch time, which hurt service levels.

Mr. Koskinen has urged Congress to restore $900 million that was cut in the initial sequester. According to him, that would go a long way to restore the level of service the agency used to deliver.
