IRS Tax Audit Statistics

In 2010 the IRS audited 1.1% of 142,823,105 individual income tax returns. After 2010, the IRS shifted its tax audit focus away from large corporations (assets over $250 million). Instead, the IRS has spread its tax audit focus among disparate taxpayers as follows:

1) Increased tax audits for pass-through entities (S-Corporations, Partnerships). Previously, in 2010, the tax audit rate was 0.4%. 

2) Corporations with assets between $250,000 and $10 million (plus) tax audit rates increased exponentially:

$5M – $10M            3.0%

$10M (plus)           16.6%

3) Individual Income Taxpayers
Tax audit rates increased correspondingly to higher income:

Income                Tax Audit Rate
$200k – $1M            4% (1 of 25)

 $1M (plus) 2011 (12.48%)

 Increased from 2010 – 8.4%
                            2009 – 6.4%

4) Taxpayer tax audit rates increased at higher adjusted gross income levels (AGI)

AGI                       Tax Audit Rate
$100k – $200k      0.71%
$200k – $500k      1.92%

2010                        1.04%
