What Qualifies as an Intangible Drilling Cost?

Intangible drilling costs cover expenditures tied to drilling and preparing a well for production that do not result in recoverable physical assets. Every dollar spent on labor to drill the hole, fuel burned by the rig, chemicals pumped into the borehole, cement squeezed down casing, and wireline services run after drilling — all of it disappears into the well. None of it has salvage value. That is precisely why §263(c) permits it to be deducted in the year it is incurred.

Tangible drilling costs cover the physical equipment and infrastructure that remain part of the well after drilling is complete — the casing itself, the wellhead assembly, the pump, the separator, the storage tank. These retain value and are recovered through depreciation under §168. The One Big Beautiful Bill Act (OBBBA, July 2025) permanently restored 100% §168(k) bonus depreciation, meaning the TDC equipment component is now also fully deductible in Year 1.

Why Accredited Investors Pay Attention to Intangible Drilling Costs

Why Intangible Drilling Costs Remain the Most Powerful Deduction for High-Income W-2 Earners

The appeal is direct. If you sit in the 35% or 37% federal bracket, a legitimate current-year deduction against active income materially reduces your after-tax cash exposure in the year of drilling. Intangible drilling costs are not a novel strategy — the §263(c) provision has been in the tax code since 1913, survived every major reform including TCJA, and was strengthened by the OBBBA in July 2025.
  • Meaningful current-year deduction — 65–80% of total program cost is typically classified as intangible drilling costs
  • Direct participation in domestic development drilling — not a fund, not a stock, not a REIT
  • §469(c)(3) active income classification — intangible drilling costs deductions offset W-2 wages with zero hours required
  • Long-term production income from the same asset — monthly distributions for 20–30+ years
  • §613A 15% percentage depletion on production income — perpetually, even after full cost recovery

The right question is not 'How large is the projected deduction?' The better question is: How does this specific program work, how will the operator report costs, and how does it look when your CPA models it against your full tax picture? Texas Oil Investments facilitates introductions to programs where those questions have clear, verifiable answers.

The §263(c) Election: How Intangible Drilling Costs Are Deducted

Section 263(c) permits taxpayers to elect to deduct intangible drilling costs for qualifying domestic oil and gas wells in the year the costs are incurred. In a properly structured working interest program, IDC flows through the partnership entity and appears on investors' annual Schedule K-1s as an ordinary loss allocation. The election must be made on the first return on which intangible drilling costs are reported and is generally binding thereafter — it cannot be reversed.

Before relying on IDC treatment, verify each of the following directly from offering documents or the operator:
  • Program structure: non-limiting LLC or general partnership — limited partnership does NOT qualify for §469(c)(3) active income treatment
  • Operator's planned intangible drilling costs / TDC allocation — confirm from the line-item AFE, not a headline percentage
  • Projected drilling and spud timeline — must align with your tax year (spud date before December 31)
  • §263(c) election statement — included in offering documents or available on written request
  • Prior year K-1 samples from the operator — your CPA should verify reporting consistency before you subscribe

§469(c)(3): The Provision That Makes Intangible Drilling Costs Usable for W-2 Earners

A deduction only has value to the extent it can offset income. Under the passive activity rules, most investment losses are passive — trapped against passive income only, unable to offset W-2 wages. Oil and gas working interests held through a non-limiting entity are specifically excluded from the passive activity rules under §469(c)(3). Intangible drilling costs deductions offset W-2 wages, S-Corp distributions, and all active income directly. No hours requirement. No professional status election. Automatic based on the entity structure the program uses.

For high-income professionals — physicians, attorneys, executives, and business owners — this distinction is not academic. Real Estate Professional Status requires 750+ hours per year and 50%+ of all working time in real estate. A physician working 50 hours per week in clinical practice spends 2,600 hours annually in medicine. The REPS hours requirement is simply not achievable for most full-time professionals. The §469(c)(3) exception for intangible drilling costs requires nothing — it is automatic based on entity structure.

The OBBBA (2025): What Changed for Intangible Drilling Costs Programs

The One Big Beautiful Bill Act (signed July 4, 2025) made three changes that directly affect investors evaluating Permian Basin working interest programs in 2026:
§168(k) Bonus Depreciation — Permanently Restored to 100%
Before OBBBA:§168(k) bonus depreciation had declined to 60% in 2024 under the TCJA phasedown schedule
After OBBBA:100% bonus depreciation permanently restored for qualifying property placed in service after January 19, 2025
Impact:the TDC component (typically 20–35% of the AFE) is now fully deductible in Year 1 — up from 60% in 2024
TDC bonus depreciation is NOT an AMT preference item:unlike intangible drilling costs, no Form 6251 addback required
Combined with IDC:2026 Year 1 deductibility of a working interest program can approach 100% of total investment

§199A QBI Deduction — Made Permanent

The TCJA's 20% qualified business income deduction was temporary — OBBBA made it permanent.

Whether working interest income qualifies depends on program structure and investor income thresholds.

Consult your CPA: real benefit for some investors, inapplicable for others based on their specific situation.

Timing: The Spud Date Controls the Tax Year

The subscription date does not determine the tax year of the intangible drilling costs deduction. The spud date does — drilling must physically commence before December 31 for the deduction to apply to that tax year. A December subscription into a program whose well is not spudded until January produces no current-year deduction. Confirm the spud date in writing from the operator before committing capital.
  • Confirm projected spud date in writing before committing capital — not an estimate, a written confirmation
  • Review the line-item AFE showing intangible drilling costs vs TDC allocation — not a headline summary percentage
  • Have your CPA model the full-year tax picture including AMT before subscribing to any year-end program
  • Verify subscription and funding timing requirements for the specific offering

Texas Oil Investments provides spud date confirmation for programs in our partner network as part of every introduction. Never commit year-end capital without this in writing.

The AMT Question: Model It Before You Invest

Intangible Drilling Costs and AMT: The Calculation Every High-Income Investor Must Run First

Intangible drilling costs deductions are preference items under §57(a)(2). When calculating Alternative Minimum Tax, the IDC deduction amount must be added back on Form 6251 Line 2j to calculate Alternative Minimum Taxable Income. This does not eliminate the deduction — it means the net benefit may be reduced for investors already in AMT territory. TDC bonus depreciation under §168(k) is explicitly NOT an AMT preference item. Only the intangible drilling costs component carries the AMT addback requirement.

Before investing, have your CPA model all of these:
  • Regular federal tax treatment — the headline deduction number from the offering materials
  • AMT exposure — how much of the intangible drilling costs benefit survives after the AMTI addback on Form 6251
  • Basis and at-risk limitations — confirm you have sufficient basis and at-risk amount to absorb the deduction
  • State tax treatment — Texas: 0% state income tax; California: 13.3%; New York: 10.9%; New Jersey: 10.75%
  • Expected timing — confirm the deduction tax year and how the K-1 will report the intangible drilling costs

Investors who model AMT before sizing their investment position more intelligently. Investors who skip this step often discover their net benefit is 20–30% lower than the offering summary implied.

What Happens if the Well Is Nonproductive?

A nonproductive well is a genuinely bad economic outcome — capital is at risk and production income does not follow. What does not automatically disappear is the tax treatment of qualifying intangible drilling costs. The §263(c) deduction arises from the actual expenditure of drilling costs, not from the well's production result. If the well is properly spudded, qualifying costs are incurred, and the operator correctly reports them on your K-1, the deduction exists independent of production.

For Permian Basin development programs, this question should be viewed in context. Wolfcamp A and B development wells in core Midland Basin counties carry approximately 5–10% dry hole risk — significantly lower than exploratory wells at 30–60%+. Texas Oil Investments facilitates introductions exclusively to development programs in proven formations with verifiable operator track records in the Texas Railroad Commission database.

How Intangible Drilling Costs Interact with Percentage Depletion

Intangible drilling costs shape the Year 1 drilling-year deduction. Percentage depletion under §613A shapes the ongoing production-income tax analysis for the 20–30+ year life of a producing well. The §613A allowance permits independent producers to deduct 15% of gross production income annually — regardless of whether the original investment has been fully recovered. Unlike depreciation, depletion does not stop when the adjusted basis reaches zero.

The 20-Year Tax Benefit Stack for a Permian Basin Well:
  • Year 1: §263(c) intangible drilling costs + §168(k) TDC — near 100% deductibility in the year of drilling
  • Years 2–30+: §613A percentage depletion — 15% of gross production income tax-free, perpetually
  • Years 2–30+: Lease operating expenses (LOE) — fully deductible against production income in proportion to working interest
  • All years: §469(c)(3) active income classification — no passive activity trap on any income
  • NIIT exemption: Working interest income is exempt from the 3.8% Net Investment Income Tax

Intangible Drilling Costs vs Other Tax Shelters: The Honest Comparison

High-income accredited investors evaluating intangible drilling costs programs are almost always comparing them against other strategies.

⚠ The Conservation Easement Warning — What Changed in October 2024

The §263(c) intangible drilling costs deduction carries none of the risks now associated with syndicated conservation easements. IDC is explicit statutory law since 1913 — reaffirmed in every major tax reform, strengthened by the OBBBA in 2025. It is not a listed transaction. For the complete 2026 comparison including penalty exposure and three investor scenarios, see our dedicated analysis. If a promoter offers you a conservation easement in 2026, have your attorney review the October 2024 Treasury regulations before any decision.

IDC vs Qualified Opportunity Zones

QOZ funds defer — not eliminate — capital gains. Intangible drilling costs deductions against active income are a different mechanism serving a different purpose. QOZ investments require existing capital gains, a 10-year hold for maximum benefit, and exit into an uncertain future market. Many investors use both in the same tax year: a QOZ fund to defer capital gains from an asset sale, and a working interest program for the ordinary income deduction. They are complementary, not competing.

IDC vs Defined Benefit Plans — Use Both, In Order

Defined benefit plans should be maxed before oil investments are sized — they provide guaranteed deductions with zero investment risk, up to $200,000–$275,000 annually depending on age and income. Once the DB plan ceiling is hit, intangible drilling costs investing addresses the remaining taxable income. Max the DB plan first, then size the oil investment to the income above that ceiling.

Tax Reduction Strategies for High Income Earners: All Options Compared

§1254 Recapture: What Happens When You Sell a Working Interest

Most educational materials on intangible drilling costs focus entirely on the entry — the Year 1 deduction. Sophisticated investors also want to understand the exit. When a working interest is sold, §1254 recapture rules apply: gain attributable to previously deducted intangible drilling costs amounts is taxed as ordinary income — not at the preferential capital gains rate — to the extent of prior deductions.
ScenarioTax Treatment on Sale
Gain below prior IDC deductionsEntire gain taxed as ordinary income under §1254 recapture
Gain above prior IDC deductionsExcess above IDC amount may be eligible for capital gains treatment
Sale at a lossNo §1254 recapture — ordinary loss treatment may be available depending on structure
Hold through well life — no saleNo §1254 recapture triggered — the issue only arises on disposition

Illustrative example only. Actual tax savings and investment returns depend on individual circumstances including tax bracket, AMT exposure, state tax treatment, program structure, and well performance. Not a projection or guarantee of results. Consult a qualified CPA before making any investment decision.

Simplified illustration only. §1254 recapture analysis depends on individual facts, holding period, basis, prior depreciation, and state tax treatment. Consult your CPA before any sale or disposition.

Most Permian Basin development investors hold through the productive life of the well — 20–30+ years — and never trigger §1254 recapture. It becomes material for investors who receive acquisition offers or are part of program buyouts. Model the §1254 recapture exposure with your CPA before accepting any offer to purchase a working interest. The headline offer price may look attractive; the after-tax proceeds may be materially lower.

IDC Amortization: When the Alternative Election Makes Sense

The §263(c) election defaults to expensing — deducting intangible drilling costs fully in the year incurred. Investors can alternatively elect to capitalize and amortize IDC over 60 months starting from first production. This election is irrevocable once made. The vast majority of investors at 35–37% benefit more from expensing the full current-year deduction. The exceptions are real but case-specific:
  • AMT-heavy years: intangible drilling costs are AMT preference items. If you are already deeply in AMT, expensing creates a large addback that partially offsets the regular-tax benefit. Amortizing reduces the AMT preference item size — at the cost of spreading the deduction over 5 years.
  • Anticipated higher-income years: if income will increase materially in Years 2–3 (practice sale, large bonus, earn-out), the deduction may be worth more in those future years than the current year.
  • State non-conformity: some states do not conform to federal IDC expensing. If your state disallows the immediate deduction regardless of your federal election, the marginal benefit of expensing federally requires careful modeling with your CPA.

The amortization election is binding and irrevocable. Have your CPA model the full multi-year picture under both scenarios — expensing and amortization — before making this decision.

How to Read Your Oil and Gas K-1: A Line-by-Line Guide

Oil and gas K-1s have specific line items that general CPAs frequently mishandle — with significant consequences for the intangible drilling costs deduction you actually receive. The single most consequential error is reporting the Box 1 IDC loss as passive income on Schedule E Part I instead of as active income on Part II. This traps the entire deduction in suspended passive losses that cannot offset your W-2 wages. See our complete CPA guide to oil & gas K-1 reporting.
K-1 BoxWhat It ShowsWhere on ReturnMost Common Error
Box 1 — Year 1Ordinary loss — intangible drilling costs allocationSchedule E, Part II — ACTIVE (non-passive)Filing on Part I as passive — traps entire IDC deduction

Not a projection or guarantee of results. Consult a qualified CPA before making any investment decision.

Verify Your K-1 Is Being Filed Correctly — Ask These Questions

  • • Ask your CPA: 'Is the Box 1 oil K-1 loss on Schedule E Part II as non-passive active income?'
  • • Review your Schedule E draft: Part II should show the working interest entity and the loss in the non-passive column
  • • Confirm Form 6251 Line 2j shows the IDC addback — if your CPA skips this, AMT may be understated
  • • Confirm the depletion schedule from the K-1 supplemental is being used, not just the Box 1 figure
  • • If your CPA has not prepared an oil and gas K-1 before, engage a CPA with energy partnership experience for this return

Three Investor Profiles: How Intangible Drilling Costs Work Across Tax Situations

The intangible drilling costs deduction works differently depending on income level, state of residence, and AMT exposure. These three illustrative profiles show how the same investment produces different net outcomes for different investors. Educational illustrations only — not projections.

Profile 1: Physician in Texas — Maximum Benefit

  • Occupation: W-2 surgeon, private practice
  • Income: $750,000 W-2
  • State: Texas — 0% state income tax
  • AMT status: Not in AMT — full regular-tax benefit applies
  • $200K investment net cost: ~$126,000 after ~$74,000 potential federal benefit
  • Outcome: Maximum benefit scenario — Texas residency + no AMT = full value of intangible drilling costs deduction

Maximum benefit scenario

Profile 2: Executive in California — AMT and State Tax Reduce the Net

  • Occupation: Technology executive — salary + RSU vesting
  • Income: $1,200,000
  • State: California — 13.3% top state rate
  • AMT status: In AMT — IDC addback reduces net benefit
  • Net federal benefit (illustrative): ~$50,000–$56,000 after AMT reduction vs. ~$74,000 without AMT
  • Key action: CPA must model AMT before sizing — do not rely on headline deduction number

CPA must model AMT before sizing

Profile 3: Business Owner in a Peak Income Year — Size to the Moment

  • Situation: Business owner — sale earn-out year + normal S-Corp income
  • Income: $800,000 (higher than normal due to earn-out)
  • State: Texas — 0% state income tax
  • Investment sized to: $300,000 to match the peak-income event
  • Net cost (illustrative): ~$189,000 after ~$111,000 potential federal benefit
  • Key insight: Peak-income years justify larger sizing — the earn-out creates the tax problem, IDC solves it

Peak years justify larger sizing

All three profiles are illustrative examples only — not projections or guarantees. AMT figures in Profile 2 are simplified estimates. Actual tax results depend on your complete tax picture, CPA analysis, program structure, state law, and many other factors. Not tax advice.

Evaluating Intangible Drilling Costs Programs: Green Lights and Red Flags

Not every program that claims an intangible drilling costs deduction is structured to actually deliver one. Structure determines whether the deduction is active or passive. Entity type determines whether it offsets W-2 wages. Timing determines whether it applies to your current tax year. Marketing materials that lead with the deduction percentage and bury the operator details are a pattern worth recognizing immediately.

✓ Green Lights — Signs of a Well-Structured Intangible Drilling Costs Program

  • • Line-item AFE provided upfront with clear intangible drilling costs / TDC separation on every cost category
  • • Non-limiting LLC or general partnership entity — explicitly confirmed in the PPM, not just described verbally
  • • Operator has 5+ years of verifiable production history in the Texas RRC database matching or exceeding type curves
  • • §263(c) election statement included in offering documents or available on written request
  • • Operating agreement includes cash call caps — typically 10–20% above original AFE amount
  • • Spud date confirmed in writing before year-end — not projected or estimated
  • • Prior year K-1 samples provided so your CPA can verify reporting format before subscribing

✗ Red Flags — What Should Make You Stop and Ask Questions

  • • IDC percentage cited without a line-item AFE — 'our wells are typically 75% intangible drilling costs' is not verifiable
  • • Limited partnership structure — this eliminates §469(c)(3) active income treatment entirely
  • • Operator with no verifiable RRC production history or fewer than 3 wells in the target formation
  • • Subscription deadline with no time for CPA or attorney review — pressure tactics are a warning, not urgency
  • • Projected returns without conservative WTI pricing ($45–$50) scenarios included in the model
  • • No operating agreement or vague cash call provisions — uncapped overruns mean unlimited downside
  • • Marketing leads with deduction size and buries production economics — both must make sense independently
  • • IDC percentage above 85% without explanation — request the line-item AFE breakdown

The 110-Year History: Why the Intangible Drilling Costs Provision Has Endured

A concern that comes up in virtually every accredited investor conversation about intangible drilling costs is legislative risk: could Congress eliminate the §263(c) deduction? Understanding the history is the most honest answer to that question.
  • 1913: Revenue Act — intangible drilling costs deductibility established the same year the modern federal income tax was created
  • 1954: Internal Revenue Code codified the election in §263(c) — the exact provision in force today
  • 1969: Tax Reform Act — restricted percentage depletion for major oil companies; intangible drilling costs completely untouched
  • 1975: Tax Reduction Act — eliminated depletion for major integrated producers; IDC untouched
  • 1986: Tax Reform Act — the most sweeping overhaul in modern history — created §469 passive activity rules with an explicit §469(c)(3) carveout for oil working interests
  • 2017: Tax Cuts and Jobs Act — significant tax changes; §263(c) and §469(c)(3) both completely unchanged
  • 2025: One Big Beautiful Bill Act — strengthened oil and gas tax treatment by permanently restoring §168(k). The opposite of elimination.

No major federal tax legislation in 110 years has eliminated the §263(c) intangible drilling costs deduction. The provision has broad bipartisan support rooted in domestic energy policy. The provisions most actively under legislative threat in 2026 are newer, more aggressive strategies — syndicated conservation easements designated as Listed Transactions in October 2024, certain captive insurance arrangements, and other recent shelter structures. Intangible drilling costs, with 110 years of statutory history and an explicit congressional rationale in domestic energy production, occupies a fundamentally different position.

Sizing Your Intangible Drilling Costs Investment: The Four-Step Framework

The question 'how much should I invest?' is not answered by a percentage of net worth or a rule of thumb — it is a tax-first calculation anchored in your specific year-end picture. Here is the framework Texas Oil Investments uses to help investors think through position sizing:
StepActionWhat This Determines
1Project full-year taxable incomeYour CPA calculates estimated AGI for the tax year after all other deductions — retirement accounts, business deductions, charitable contributions. This is the gross number the intangible drilling costs investment targets.
2Subtract non-IDC deductionsIdentify remaining taxable income above the 32% bracket threshold. Intangible drilling costs deliver maximum value at 35–37%. Income below 32% produces diminishing returns on the deduction.
3Run the AMT modelYour CPA models AMT exposure specifically. AMT reduces but does not eliminate the net benefit. The AMT model determines actual net deduction value, not just the headline intangible drilling costs number.
4Calculate investment sizeTarget deduction ÷ IDC percentage = investment size. Example: targeting $150,000 in intangible drilling costs deductions from a 75% IDC program requires a $200,000 investment ($150,000 ÷ 0.75). Size to your tax picture, not to the program maximum.

Illustrative example only. Actual tax savings and investment returns depend on individual circumstances including tax bracket, AMT exposure, state tax treatment, program structure, and well performance. Not a projection or guarantee of results. Consult a qualified CPA before making any investment decision.

Common Mistakes Investors Make With Intangible Drilling Costs

Five Common Intangible Drilling Costs Mistakes That Cost Investors the Deduction

  • 1. Wrong entity structure — eliminates the entire active income benefit: A limited partnership interest does not qualify for §469(c)(3) active income treatment. The intangible drilling costs deduction sits in suspended passive losses and cannot offset W-2 wages. Confirm non-limiting LLC or general partnership before subscribing to any program. This is the first question, not the last.
  • 2. Focusing on the headline deduction without modeling AMT: The top-line intangible drilling costs estimate in a program summary is not your net federal tax benefit. It is the starting point. Run the AMT model before you invest. Investors who skip this step often discover their net benefit is 20–30% lower than the summary implied.
  • 3. Accepting estimated IDC percentages without a line-item AFE: Offering materials show expected allocations. The final intangible drilling costs percentage depends on actual expenditures and the operator's final tax reporting. Verify from the line-item AFE, not a percentage on a summary sheet.
  • 4. Investing without verifying the operator's Texas RRC track record: Intangible drilling costs improve after-tax efficiency. They cannot replace operator execution or offset production economics that do not make sense at conservative oil pricing. The Texas Railroad Commission database at rrc.texas.gov provides free, public access to every Texas operator's actual production history. Use it before you invest.
  • 5. Not accounting for state taxes in the net benefit calculation: Federal tax treatment is only part of the analysis. Texas investors pay zero state income tax on production income — one reason Texas Oil Investments focuses primarily on Permian Basin programs. Investors in California, New York, or New Jersey face materially different net economics on the same gross deduction and production income. Model state tax with your CPA before sizing.

Common questions from investors evaluating intangible drilling costs deductions. For more, explore the tax benefits of oil investments, how oil well investments work, and how to invest in Texas oil wells.

Can I claim an intangible drilling costs deduction in the first year I invest?

+
Potentially yes — if the well is spudded before December 31, the program is properly structured, and the operator reports qualifying intangible drilling costs on your K-1. The controlling event is the spud date, not the subscription date. Your CPA should review the AFE and expected K-1 reporting before you commit capital to any program.

Does §469(c)(3) active income treatment apply automatically?

+
No — it depends on structure. The working interest must be held through a non-limiting entity (non-limiting LLC or general partnership) to qualify. A limited partnership interest is specifically excluded from §469(c)(3). This is the most important structural question to confirm before subscribing.

Will AMT reduce the value of the intangible drilling costs deduction?

+
It can. Intangible drilling costs deductions are preference items under §57(a)(2) and must be added back on Form 6251 Line 2j when calculating Alternative Minimum Taxable Income. TDC bonus depreciation under §168(k) is not an AMT preference item. Investors already subject to AMT should have their CPA model the net benefit specifically before committing capital.

What did the OBBBA change for 2026 intangible drilling costs programs?

+
The OBBBA permanently restored 100% §168(k) bonus depreciation for qualifying property placed in service after January 19, 2025. The TDC component is now fully deductible in Year 1 — up from 60% in 2024. The §263(c) intangible drilling costs provision itself was unchanged. Combined, 2026 programs can approach 100% Year 1 deductibility.

Does percentage depletion apply to working interest owners?

+
Potentially yes. The §613A percentage depletion allowance at 15% of gross income is available to independent producers holding working interests through qualifying entities. Statutory income limitations, basis constraints, and program structure all affect the determination — confirm with your CPA.

What is §1254 recapture and when does it apply?

+
§1254 recapture applies when a working interest is sold. Gain attributable to previously deducted intangible drilling costs is taxed as ordinary income — not capital gains rates — to the extent of prior deductions. Most Permian Basin investors hold through the well life and never trigger this. Model §1254 exposure with your CPA before accepting any acquisition offer.

Should I expense or amortize intangible drilling costs?

+
Most investors at 35–37% benefit more from expensing — the full current-year deduction. Consider amortization only if you are deeply in AMT in the current year, or if you anticipate materially higher income in Years 2–3. The amortization election is irrevocable once made — model the multi-year picture with your CPA before deciding.

What is the most common K-1 filing error for oil and gas investors?

+
Reporting the Box 1 intangible drilling costs loss as passive income on Schedule E Part I instead of as active income on Part II. This traps the entire IDC deduction in suspended passive losses that cannot offset W-2 wages. Ask your CPA specifically: 'Is the oil K-1 on Schedule E Part II, non-passive column?' before the return is filed.

Can I hold a working interest inside my IRA?

+
Working interests inside a self-directed IRA generate Unrelated Business Taxable Income (UBTI), requiring a separate Form 990-T filing and potentially requiring the IRA to pay taxes. This typically eliminates the intangible drilling costs deduction's intended advantage. Most advisors recommend holding working interests in taxable accounts — confirm with your CPA.
