Capital gains: oil and gas
Oil and gas deductions in a high income year
A working interest in an oil or gas well can produce a large deduction for intangible drilling costs in the year they are paid. Whether that deduction reaches your wages or only your passive income depends on a single choice: the legal form in which you hold the interest.
The deduction
Why drilling costs are treated differently
Most of what it costs to drill a well is spent and gone the moment the well is drilled: labour, site work, fluids, cement, fuel and rig time. These are intangible drilling costs. IRC 263(c) and Treas. Reg. 1.612-4 let the holder of a working interest deduct them in the year they are paid, instead of recovering them slowly over the life of the well.
The election is made simply by claiming the deduction on the return for the first year the costs are paid. It then binds every later year, and not claiming it in that first year is itself an election to capitalise.
Once a well produces, percentage depletion may add a second deduction against the income it earns.
The deciding question
The form of the interest decides what the deduction can reach
IRC 469(c)(3)(A) takes a working interest out of the passive activity rules only if you hold it directly or through an entity that does not limit your liability. Accepting that liability is the price of a deduction that reaches wages.
| How it is held | Passive status | What it can offset |
|---|---|---|
| General partner interest | Not passive. The interest does not limit your liability, so IRC 469(c)(3)(A) applies. | Ordinary income including wages, subject to the basis, at-risk and excess business loss limits. |
| Limited partner interest | Passive. Treated as limiting liability under Treas. Reg. 1.469-1T(e)(4)(v). | Passive income only. Unused deductions carry forward under IRC 469(b). |
| LLC member interest | Passive, for the same reason: state law limits the member's liability. | Passive income only, on the same terms as a limited partner. |
| Held in a retirement account | The question becomes unrelated business taxable income, not passive status. | Nothing on your personal return. A cost-bearing working interest generally creates UBTI for the account, and an LLC wrapper does not change that. |
The ceilings
Limits that apply even when the deduction is non-passive
No investor can offset unlimited income with drilling deductions. These apply in order, and each one can hold part of the deduction back for a later year.
| Limit | Source | Effect |
|---|---|---|
| Basis | IRC 704(d) | A partner cannot deduct losses beyond the adjusted basis of the partnership interest. The excess waits for future basis. |
| At risk | IRC 465 | Losses are allowed only up to the amount you actually have at risk. Oil and gas is named expressly in 465(c)(1)(D). |
| Excess business loss | IRC 461(l) | Net business losses above an inflation-indexed threshold cannot offset non-business income in the current year. The excess becomes a net operating loss carryforward. |
| Depletion ceiling | IRC 613(a) | Percentage depletion cannot exceed 100 percent of the taxable income from the property, computed without depletion. |
| Depletion and total income | IRC 613A(d)(1) | For an independent producer, percentage depletion cannot exceed 65 percent of overall taxable income. |
| Minimum tax | IRC 57(a)(2)(E) | Independent producer IDCs are largely excluded as a preference item, but the relief cannot cut alternative minimum taxable income by more than 40 percent. |
On a capital gain specifically. A gain from selling an investment generally is not business income for the IRC 461(l) limit. So in a year with a large gain and little other business income, much of a drilling deduction above the threshold may carry forward rather than reduce that year's tax. Model it with your CPA before committing.
Where we fit
Set against the rest of the year, not in isolation
A drilling deduction is only worth what your return can actually use. We hear you out on the gain, your ordinary income and your appetite for liability, and if this approach fits, we connect you with a partner firm that works in oil and gas.

- Whether the timing still works before December 31.
Questions
Oil and gas deduction questions
Does an oil and gas deduction defer my capital gain?
Not in the way a 1031 exchange does. A drilling deduction reduces taxable income in the year it is allowed. An investment gain generally does not count as business income for the excess business loss limit in IRC 461(l), so a large drilling deduction cannot absorb an unlimited amount of gain in the same year. Owners usually look at this tool in a year when ordinary income is also high.
What is an intangible drilling cost?
The part of drilling a well that has no salvage value: labour, site preparation, surveying, drilling fluids, chemicals, cement, fuel and rig time. Equipment that can be recovered and reused, such as casing, wellheads, tanks and pumps, is a tangible cost and is depreciated instead. Treas. Reg. 1.612-4 draws the line.
Can the deduction offset my W-2 wages?
Only if the working interest is held directly or through an entity that does not limit your liability, which in practice means a general partner interest. Limited partner and ordinary LLC member interests are liability-limited, so their deductions are passive and cannot reach wages.
What is percentage depletion?
A deduction for an independent producer of 15 percent of gross income from the property, set by IRC 613A(c)(1). Each partner computes it separately. Because it is based on income rather than basis, it can continue after your basis in the property reaches zero.
Is there a deadline at year end?
There is a timing rule, and it is narrower than it is often described. For a tax shelter as defined in IRC 461(i)(3), amounts prepaid for drilling can be deducted in the year paid if drilling begins within 90 days after year end, under IRC 461(i)(2)(A). Whether it applies depends on the arrangement, so confirm it with your CPA.
