Chapter 6 of 7Oil & Gas Deductions
Large Deductions From Energy Investments
Intangible drilling costs are one of the very few things in the tax code that let a passive investment offset active ordinary income. That is the entire reason a high earner looks at this — and it is not a reason to ignore the well.

The short versionIf you read nothing else on this page, read these three.
- 1Oil and gas earns its place in a tax book because of a statutory carve-out, not the size of the write-off: a working interest in a well is one of the very few investments whose losses can offset a large salary or business income.
- 2The deduction belongs to whoever bears the drilling costs, so you cannot buy the tax benefit without also buying the operating risk, the liability, and the possibility of being asked for more money.
- 3A write-off lowers the cost of being wrong; it does not make you less wrong. Judge the operator, the geology, and how many wells the program drills first — and commit only money you could lose entirely.
Why drilling costs deduct in year one
Most of a well’s cost is consumed in the drilling itself, and the code lets you deduct it currently.
A surgeon, an executive with a big bonus, or a practice partner does not have a capital gain problem — the exchanges and Opportunity Zone funds do nothing for them. They have a large W-2 or K-1 taxed at the top rates, and the intangible drilling cost deduction is the most significant thing that reaches it.
Intangible drilling costs — the non-salvageable spend of drilling: labor, fluids, rig time — can generally be deducted in the year incurred rather than capitalized. And a working interest is carved out of the passive activity rules, so that loss can offset active income instead of being suspended. Take either half away and the strategy collapses.
Drilling produces two kinds of cost. Tangible costs are equipment with salvage value — casing, wellhead, tanks — capitalized and depreciated. Intangible costs are everything consumed by the drilling itself, typically the large majority of a well’s cost, and the code allows an election to deduct them currently. Congress has kept that election because it wants domestic wells drilled.
The result is a large first-year deduction relative to capital invested, with the rest deducted as equipment depreciates and production begins. That is why so much of this capital raising happens in the fourth quarter — and why a program that has not drilled by year-end may not deliver the deduction its marketing described.
The deduction follows the drilling, not the subscription, and the alternative minimum tax and at-risk rules can further limit what you finally deduct. Anyone quoting a figure before seeing your return is describing the program, not your outcome.
The two ways to own a well
Only a working interest gets the deduction and the carve-out, and only because it also carries the costs and liability.
A working interest is an ownership stake in the well’s operation: you share the costs of drilling and producing, and you carry the liabilities of operating. A royalty interest is a right to a share of production revenue with no obligation for costs.
| Working interest | Royalty interest | |
|---|---|---|
| What you own | A share of the drilling and producing operation | A share of production revenue, no costs |
| Cost exposure | Drilling, completion, and operating costs, plus overruns | None — the working interest owner’s problem |
| Passive activity treatment | Carved out; losses can offset active ordinary income | Passive or portfolio; no offset |
| Intangible drilling cost deduction | Available to the working interest owner | Not available — you did not incur the cost |
| Liability | Operational and environmental, limited by entity structure | Generally none |
| Why you would choose it | The deduction against ordinary income | Cash flow without operating risk |
You cannot buy the deduction and keep the royalty’s risk profile; the tax benefit exists because you took the risk that generates it. If you want energy exposure without operating risk, a royalty interest or a diversified energy fund is the better vehicle.
The deduction once the well produces
Depletion shelters part of your production income while the well pays out, but it is never the reason to invest.
The depletion allowance recognizes that a producing well is selling off a finite reserve. Cost depletion recovers your basis in proportion to production; percentage depletion allows a statutory percentage of gross income, subject to limits and eligibility rules that favor smaller producers and independent investors over integrated companies.
Your CPA determines which applies; either way it shelters part of your production income while the well pays out. It is a secondary benefit, though — if a program’s case rests on it, ask why the drilling economics were not enough.
What you own if you ignore the tax
Underneath the deduction is equity in a small industrial project with a binary outcome, so diligence means operator diligence.
Strip out the tax treatment and a working interest is equity in a small industrial project with a binary outcome and a commodity price you do not control. Wells come in dry or decline faster than the projection, completion costs run over, operators get into trouble, and natural gas has repeatedly sold at prices that make competent wells uneconomic.
A tax deduction does not rescue a bad well. If you invest $200,000 and the deduction saves a meaningful fraction at your marginal rate, you have reduced your cost of being wrong — you have not hedged it. The rest is at risk, and losing all of it on a given well is a normal outcome.
Diligence here is operator diligence, not fund diligence. What is the operator’s completion record in this formation? Are these development wells next to known production, or exploratory wells with real geological uncertainty? How many wells does the program drill — one is a bet, twelve is a portfolio? What are the fees and the promote, and how much of your subscription reaches the ground? Are there capital calls if costs exceed budget? The broader context is in energy investments.
Who this fits and who it does not
This is built for a large, recurring ordinary income problem and the net worth to absorb losing the position.
This fits someone with a large, persistent ordinary income problem, enough net worth that a total loss on the position is an annoyance rather than a setback, a genuine tolerance for binary outcomes, and the discipline to spread capital across multiple wells and multiple years. It fits particularly well for someone with a one-off income spike — a large bonus, a practice buyout, a bunched year — where a current deduction has unusual value.
It does not fit someone whose problem is a capital gain, because the deduction is aimed at the wrong kind of dollar and there are better tools in this book for that. It does not fit someone who needs the capital back on a schedule, since production income arrives unevenly over years. And it does not fit someone who would be investing an amount they cannot lose — which, given the distribution of drilling outcomes, is the disqualifying condition more often than any other.
This category is legitimate, useful for a narrow set of income profiles, and the easiest place in this book to get hurt. The strength of the incentive attracts sponsors whose real product is the deduction — a program that cannot make its case without the write-off is telling you something. I would rather see a client pay tax on a bonus than put six figures into a well nobody would drill on the geology alone.
Common questions
- Why can oil and gas losses offset my W-2 income when real estate losses usually cannot?
- Because a working interest in oil and gas is specifically excluded from the passive activity rules, while rental real estate generally is not unless you meet the real estate professional tests. That statutory carve-out is what makes this category distinctive for a high-income earner. It applies to working interests, not to royalty interests.
- How much of my investment is deductible in the first year?
- Intangible drilling costs are typically the large majority of a well’s cost and are electable as a current deduction, with tangible equipment costs depreciated over time. What you actually deduct depends on your program structure, when the costs are incurred, and limitations on your own return. Ask your CPA to model it against your return rather than relying on a program summary.
- What is the difference between a development well and an exploratory well?
- A development well is drilled near known production into a formation with established results, so the geological uncertainty is lower. An exploratory well tests an unproven area and carries a materially higher chance of no commercial production. Programs vary widely on this mix, and it is one of the most important questions to ask.
- Can I lose more than I invest?
- Depending on the program structure you may be exposed to additional capital calls if drilling or completion costs exceed budget, and a working interest carries operating and environmental liability that entity structure is designed to limit. Read the subscription documents on both points specifically, and have your attorney confirm what your maximum exposure actually is.
