That same logic still drives oil and gas partnerships today, though the terminology gets murky fast. This guide breaks down what carried interest actually means in oil and gas deals, how the structure works, and how the IRS taxes it.
One clarification up front: "carried interest" and "carried working interest" get used interchangeably, but they're not identical. We'll untangle both.
Key Takeaways
- Carried interest lets a party share profits without contributing capital
- In oil and gas, a carried working interest means one party covers another's costs until payout
- Long-term capital gains treatment requires a 3-year holding period under the Tax Cuts and Jobs Act
- Distinguish carried, working, and royalty interests before evaluating any oil and gas deal
What Is Carried Interest in Oil and Gas?
Carried interest is a profit share paid for expertise or labor, not capital. In private equity or hedge funds, managers typically take a standard 20% profit share above a hurdle rate. The Congressional Research Service notes that percentage tracks the top long-term capital gains rate. Oil and gas partnerships used this same "pay for expertise" logic decades before Wall Street adopted it.
In upstream oil and gas, the term almost always refers to a carried working interest. The parties break down as follows:
- Carrying party: advances 100% of drilling and completion costs
- Carried party: contributes the lease, technical know-how, or operational role
- Payout trigger: carried party earns nothing until a defined cost-recovery milestone is reached
As Schlumberger's Energy Glossary defines it, this structure lets non-operating partners, including accredited investors, gain exposure to a well's upside without running daily operations. The carrying party fronts the risk; the carried party's interest "backs in" once costs are recovered.
How Carried Interest Works: An Oil and Gas Example
Picture two partners drilling a well in a South Texas basin.
- Partner A (carrying party) funds 100% of the $2 million drilling and completion cost
- Partner B (carried party) contributes the lease and technical oversight, earning a reduced revenue share (about 15%) until Partner A recoups the $2 million
Before payout:
- Partner A collects the bulk of revenue against the outstanding cost balance
- Partner B receives a smaller carried percentage, with no cash outlay required
After payout:
- Revenue splits revert to the original working interest percentages (often 50/50)
- Partner B also shares ongoing operating costs once the carry ends
This structure is common in Gulf Coast and Texas drilling partnerships, where operators need capital partners without diluting technical control. The Texas Bankers Association treats it as a distinct category alongside working and royalty interests.
Carried Interest vs. Working Interest vs. Royalty Interest
These three terms get confused constantly. Here's how they actually differ:
| Structure | Cost Responsibility | Tax Treatment | Control |
|---|---|---|---|
| Working interest | Pays proportional share of ongoing costs | Active income; exempt from passive-activity limits under IRC §469 | Operational decision-making |
| Royalty interest | No cost exposure | Passive/portfolio income, generally | None — pure revenue share |
| Carried working interest | Costs covered by another party until payout | Same active-income treatment as working interest (carve-out applies even while carried) | Limited until back-in after payout |
The IRS treats working interest holders as active participants in a trade or business, regardless of day-to-day involvement. IRS Publication 925 confirms this passive-activity carve-out applies whether the holder has been carried or not.
Royalty owners don't get that exemption. Their income is generally stuck under passive-activity rules.
Tax Treatment of Carried Interest in Oil and Gas
The 2017 Tax Cuts and Jobs Act reshaped how carried interest gets taxed. Under IRC Section 1061, an asset tied to carried interest must be held for more than three years to qualify for long-term capital gains treatment. Miss that window, and the gain gets recharacterized as short-term.
Here's what that means in dollars:
- Held 3+ years: taxed at the top long-term capital gains rate of 20%, plus a possible 3.8% Net Investment Income Tax for high earners
- Held under 3 years: taxed as ordinary income, up to 37%
That's a meaningful gap. The CRS report notes carried interest paid to fund managers is often treated as active partnership income and may fall outside NIIT. That treatment is case-specific, not a bright-line rule.
Compare that to working interest income, which is treated as active from day one. Working interest holders can deduct intangible drilling costs (IDCs) against ordinary income, including W-2 wages. Traditional carried interest holders do not get that same IDC offset.
Independent producer groups have pushed hard to keep this structure intact. In an April 2025 letter to congressional leadership, the IPAA called the model "particularly critical in the oil and natural gas industry," and most embedded along the Gulf Coast, where it helps independents pair with private capital to fund exploration.
Why Investors Consider Direct Working Interest for Tax and Income Strategy
Carried interest gets attention, but direct working interest positions offer their own tax advantages, and they work differently. Instead of waiting on a carrying party to recoup costs, investors take direct ownership from day one, along with the deductions that come with it.
PetroVybe's model illustrates this. Accredited investors gain direct working interest exposure to natural gas development across its South Texas, Gulf Coast Basin position in Lavaca County — roughly 400 existing wells plus 57+ planned new wells across 58,000 acres, backed by a third-party engineered $48 million reserve valuation (PV-09).
What stands out about this structure:
- First-year deductions against active income: partners saw 94% in 2024 and 91% in 2025, driven largely by IDCs (typically 60–80% of capital)
- Targeted 10-year MOIC of ~2.2x–5.8x, with an IRR near 26%
- 80/20 investor-favorable profit split inside a compound capital model that reinvests cash flow over the hold
Unlike a pure carried interest deal, where the carried party waits on someone else's capital, or a passive royalty with capped upside, direct working interest compounds over time and builds toward long-term production income.
Participation generally targets investors with $100,000 or more in liquidity who meet SEC accredited investor thresholds, verified through a CPA, attorney, or financial adviser.
Frequently Asked Questions
What is the 3-year rule for carried interest in the US?
The Tax Cuts and Jobs Act requires assets tied to carried interest be held more than three years to qualify for long-term capital gains rates. Sell before then, and gains are taxed at ordinary income rates instead.
What does a 15% or 20% carried interest mean?
It typically refers to the percentage of profits above a hurdle rate that a managing partner or carrying party receives for their expertise. This convention shows up in both fund management and oil and gas partnership deals.
What is an example of carried interest?
In a drilling partnership, one partner funds 100% of well costs while the other contributes the lease and earns a reduced share. Once the funding partner recoups costs (payout), splits typically revert to the original working interest percentages.
How is carried interest different from working interest in oil and gas?
Working interest involves ongoing cost-sharing from the start and gets active income tax treatment. Carried interest means one party temporarily covers the other's costs before profit splits revert to standard terms.
Is carried interest considered passive or active income?
It depends on the structure and the holder's involvement. Given how complex passive-activity rules get, it's worth talking to a tax professional before assuming either classification.
Why has carried interest tax treatment remained controversial?
Critics argue it's compensation dressed up with preferential capital gains rates. Energy and investment groups counter that it's essential for attracting capital into independent oil and gas development, particularly along the Gulf Coast.
