Attention multimillionaires, the watchful eye of the Internal Revenue Service is trained on you.
During last year's tax season, 30% of taxpayers making an adjusted gross annual income of $10 million or more were audited, the agency said, up from 18% in 2010. Overall, just 1.1% of individual income tax returns were checked.
Nearly 21% of Americans making between $5 million and $10 million annually had their returns inspected, the IRS said; 12% of millionaires making less underwent the same process.
From Oct. 1, 2010, through Sept. 30, 2011, the agency said it collected $2.4 trillion in taxes from 234 million processed returns, up from the $2.3 trillion collected the year before. It was the first year of increased revenue since 2008.
