Here are the steps to solve this example:
1. O'Neill Machinery's taxable income is $1,445,500 which is greater than the $659,000 cost of the asset, so the full $500,000 Section 179 deduction can be taken.
2. The Section 179 deduction reduces the asset basis to $159,000 ($659,000 original cost - $500,000 Section 179 deduction).
3. The MACRS depreciation on the remaining $159,000 basis is 14.29% of $159,000 = $22,701 (using the MACRS table for a 7-year asset).
4. The total depreciation deduction for the current year is
