Finally, section 179(b)(3) provides that a taxpayer's § 179 deduction for any taxable year may not exceed the taxpayer's aggregate income from the active conduct of trade or business by the taxpayer for that year. If, for example, the taxpayer's net trade or business income from active conduct of trade or business was $72,500 in 2006, then the taxpayer's § 179 deduction cannot exceed $72,500 for 2006. However, the § 179 deduction not allowed for any year because of this limitation can be carried over to the next year.
