WASHINGTON — The Internal Revenue Service audited 18.4 percent of taxpayers reporting income above $10 million last year, up from 10.6 percent the previous year.

Audit rates increased in 2010 for all income groups, except for people with no adjusted gross income, according to figures released yesterday for the fiscal year that ended Sept. 30. The IRS audited 11.6 percent of taxpayers reporting adjusted gross income between $5 million and $10 million, up from 7.5 percent the year before. Taxpayers making between $75,000 and $100,000 faced the least chance of an audit, with a 0.64 percent rate.
