Section 179 Addback
When a pre-1987 asset on which the Section 179 expense deduction has been taken is disposed of during either of the two taxable years following the acquisition year, all or part of the Section 179 expense must be added back to the asset's basis (that is, recaptured).
The calculation for the amount added back to the basis is:
Section 179 taken
- Depreciation on 179 amount
Section 179 addback
where the depreciation on the Section 179 is the amount of depreciation that would have been taken on the Section 179 amount had there been no Section 179 deduction.
