Short Answer
Three core benefits drive after‑tax returns:
- IDCs: Often 60–85 percent of upfront costs, typically deductible when incurred for working‑interest owners who elect to expense.
- TDCs: Equipment is depreciated, generally on 5‑ or 7‑year MACRS schedules, with bonus depreciation where eligible.
- Depletion: Eligible owners may deduct 15 percent of gross income per property, subject to limits.
What It Means to an Investor
IDC expensing can lower effective capital at risk in Year 1. TDCs provide steady deductions in later years. Percentage depletion continues even after basis is recovered, subject to per‑property and overall limits. Maintain CPA‑ready records and confirm Section 469 treatment.
