WASHINGTON (AP) — An IRS watchdog says the agency is cutting taxpayer services just as President Barack Obama's health law will make filing a federal tax return more complicated for millions of families The IRS says only half of the 100 million taxpayers expected to call the agency this year will be able to reach a person. Callers who get through may find themselves on hold for 30 minutes or more. National Taxpayer Advocate Nina Olson said taxpayers will suffer. Olson runs an independent office within the IRS.

In her annual report to Congress, Olson said some taxpayers might make costly mistakes because they can't get help, while others will simply give up and not file a return. IRS Commissioner John Koskinen says budget cuts are forcing the agency to reduce taxpayer services.
