In 2009, the personal exemption was $3,750 per person. The income ranges over which personal exemptions phase out, which are indexed to inflation, were:

The 2009 reduction cannot exceed one-third of a taxpayer’s full exemptions; thus, each exemption cannot be reduced below $2,333. That maximum reduction occurs when AGI exceeds the relevant threshold by more than $122,500.

In addition, the 2001 tax act decreases the reduction in 2009 to 1/3 of its full value.
