Example. In 1999, Corporation M, a calendar year S corporation, purchases and places in service section 179 property costing $10,000. Corporation M elects to expense the entire cost of the property. Shareholder A owns 50 percent of the stock of Corporation M. Shareholder A's pro rata share of this item after Corporation M applies the section 179(b) limitations is $5,000. Because the aggregate amount of Shareholder A's pro rata share and separately acquired section 179 expense may not exceed $19,000 (the aggregate maximum cost that may be taken into account under section 179(a) for the applicable taxable year), Shareholder A may elect to expense up to $14,000 of separately acquired section 179 property that is purchased and placed in service in 1999, subject to the limitations of section 179(b).
Example. Shareholder A, an individual, owns 25 percent of the stock of Corporation N, an S corporation that has $10,000 gross income and $2,000 taxable income. A reports only $300 as A's pro rata share of N's taxable income. A should have reported $500 as A's pro rata share of taxable income, derived from A's pro rata share, $2,500, of N's gross income. Because A's return included only $300 without a disclosure meeting the requirements of section 6501(e)(1)(A)(ii) describing the difference of $200, A is regarded as having reported on the return only $1,500 ($300/$500 of $2,500) as gross income from N.
