2012 Deduction Limit = $139,000
This is good on new and used equipment, as well as off-the-shelf software.
2012 Limit on equipment purchases = $560,000
This is the maximum amount that can be spent on equipment before the Section 179 Deduction available to your company begins to be reduced.
Bonus Depreciation = 50%
This is taken after the $560k limit in capital equipment purchases is reached. Note: Bonus Depreciation is available for new equipment only. Bonus Depreciation can also be taken by businesses that will have net operating losses in 2012.
