Oil and gas tax education

A practical guide to partnership basis, at-risk rules, passive losses, and other limits that affect when an oil and gas deduction can be used.

An oil and gas direct participation program, or DPP, can allocate a substantial tax loss to an investor. Whether that loss reduces this year's tax bill depends on the investor's circumstances as well as the program's structure.

The amount reported to you is the starting point. Before claiming it, your tax preparer must determine how much passes the applicable loss limitations. Two investors receiving the same allocation can end up with different current deductions.

This guide focuses on an individual investing through a DPP taxed as a partnership. Direct ownership and other arrangements can involve different reporting and basis calculations. The practical question remains the same: how much of the potential deduction can you use now, and what happens to the rest?

Start with the allocated loss

An investment contribution is money you put into a program. The program uses funds for purposes such as drilling, equipment, acquisitions, and operating expenses. Those expenditures, together with income and other tax items, help determine what is allocated to investors.

In a partnership structure, Schedule K-1 and its supporting statements report your share of the relevant items. Receiving a loss allocation does not by itself establish that the full amount is deductible on your return.

For partnership investors, the IRS specifies the following order for applying loss limitations. IRS Schedule K-1 instructions

OrderLimitationQuestion it addresses
1Tax basisIs there enough adjusted basis in your partnership interest to support the loss?
2At-risk rulesHow much is treated as economically at risk under the tax rules?
3Passive-activity rulesCan the loss offset the income you want to reduce?
4Excess-business-loss rulesDo your combined business results create an additional current-year restriction?

An amount that passes one step may still be limited at the next. Keep the sequence in mind when reviewing a tax illustration that assumes the whole allocation is immediately usable.

First, establish your tax basis

For a partnership investment, the relevant starting point is your adjusted tax basis in the partnership interest, often called outside basis. This differs from the partnership's basis in its wells or equipment.

Basis changes over time. Contributions, allocated income, distributions, prior losses, and changes in your share of partnership liabilities can affect it. The original amount you invested is therefore not necessarily your current basis. IRS Publication 541

Suppose you receive a $50,000 allocated loss and have $30,000 of adjusted outside basis available to absorb it. The basis limitation allows $30,000 to proceed to the remaining tests. The other $20,000 is suspended under the basis rules. Passing the basis test does not yet make the $30,000 deductible; the later limitations still apply.

Your K-1 capital account is also not a substitute for an outside-basis calculation. The IRS notes that capital-account information can differ from adjusted basis, including because of partnership liabilities and investor-level adjustments. IRS Schedule K-1 instructions

This is why your preparer needs an updated basis schedule, especially when you have held an interest for several years, received distributions, or acquired it from another investor.

Next, determine how much you have at risk

The at-risk rules address the amount you can lose under the tax rules. Cash invested without loss protection generally contributes to that amount. Certain borrowed amounts can also qualify, but financing terms and the source of the borrowing matter.

Tax basis and the amount at risk can diverge. For example, an allocated share of nonrecourse partnership debt may increase outside basis without creating the same increase in the at-risk amount. Nonrecourse financing generally means the lender's recovery is limited to specified collateral rather than the borrower's broader assets.

Arrangements that protect an investor against loss can also affect the calculation. A guarantee or stop-loss arrangement requires review; a projection showing an attractive tax deduction does not resolve that question. The IRS describes these distinctions in its Form 6198 instructions.

Consider what this means when evaluating a program. A statement that financing increases your tax basis does not establish that the associated losses pass the at-risk test. Your CPA needs the actual borrowing and protection terms.

Paying cash can make the analysis simpler, but it does not remove the need to check the remaining loss limitations.

Then determine whether passive-activity rules apply

“Passive income” has a specific tax meaning. It is easy to confuse it with the everyday description of receiving income without managing an investment yourself.

Under the general passive-activity rules, losses from a passive activity ordinarily offset qualifying passive income. Wages and portfolio income, such as ordinary interest and dividends, generally do not provide that offset. Publicly traded partnerships have additional restrictions and should be considered separately. IRS Form 8582 instructions

Oil and gas has a working-interest exception. A qualifying working interest held directly or through an entity that does not limit the investor's liability is not treated as a passive activity, even without material participation. The exception depends on the ownership and liability arrangement. The DPP label alone does not establish eligibility. IRS Publication 925

An entity that owns working interests does not automatically give every investor nonpassive treatment. If the exception does not apply, the activity must be evaluated under the applicable participation and passive-activity rules.

BassEXP's guides to the Section 469 working-interest exception and entity structure examine these distinctions in more detail.

Before using a projected loss to estimate a reduction in taxes on wages, establish which classification applies to your actual interest.

Check the excess-business-loss limitation

A loss can pass the earlier tests and still face another restriction. The excess-business-loss rules apply to noncorporate taxpayers and consider combined trade or business results, subject to the applicable annual threshold and calculation rules.

This is broader than a review of a single DPP. Your preparer needs information about your other business activities. Employee wages are excluded from the business-income calculation used for this limitation, so a large salary does not remove the restriction.

An excess business loss disallowed for the current year is treated as a net operating loss carryover for subsequent years. Its later use is subject to the NOL rules; it is not a promise that the entire amount can be deducted next year. IRS Form 461 instructions

The annual threshold should be checked for the tax year being modeled. A prior-year illustration can be useful for understanding the mechanics while still requiring updated figures.

How one loss moves through the sequence

Suppose an investor receives a $50,000 allocated passive loss. Before applying that loss, the preparer determines that $30,000 of outside basis and $20,000 at risk are available. The investor also has $8,000 of available qualifying passive income from another activity. Assume the excess-business-loss test and other rules create no further restriction.

StepLoss passing this stepAmount suspended at this step
Basis limitation$30,000$20,000
At-risk limitation$20,000$10,000
Passive-activity limitation$8,000$12,000

The current deduction is $8,000. The remaining $42,000 belongs in three separate suspended-loss records. Each step considers the amount that passed the previous step; the same dollars are not suspended twice.

A passive DPP example: two investors, different current deductions

Consider two hypothetical investors in the same non-publicly-traded partnership. Each contributes $100,000 and receives a $90,000 loss allocation.

For this example, both investors' interests generate passive losses. Each has sufficient basis and amount at risk. The only difference shown is the qualifying ordinary passive income available to absorb the loss after accounting for other passive losses. Assume no remaining limitation or other tax interaction changes the results.

These assumptions do not describe the tax classification or projected results of a BassEXP offering.

ItemInvestor AInvestor B
Contribution$100,000$100,000
Allocated passive loss$90,000$90,000
Available qualifying ordinary passive income$90,000$20,000
Currently usable loss$90,000$20,000
Passive loss suspended$0$70,000
Illustrated federal tax saving at 37%$33,300$7,400

The tax-saving figures assume every dollar of the allowed deduction reduces income that would otherwise be taxed at 37%. They exclude state taxes and other tax interactions.

Investor A can use the full $90,000 loss in the illustration. Investor B uses $20,000 and carries a $70,000 suspended passive loss. The second investor's smaller current deduction results from the available passive income, even though the contribution and loss allocation match Investor A's. Our five-year DPP tax example follows a suspended loss like this one until it is used.

Neither number is a projected refund. Whether an investor receives a refund also depends on withholding, estimated payments, and the rest of the return. Our $100,000 deduction example shows the difference between a deduction and the tax it saves.

A qualifying nonpassive working interest would require a different analysis at the passive-activity step. Basis, at-risk, and excess-business-loss considerations would still need review.

Keep deferred losses in separate records

“I have a loss carryforward” is not enough information to determine when it becomes usable. The reason for the restriction matters.

What restricted the loss?What needs to be reviewed in a later year?
Insufficient basisWhether sufficient partnership-interest basis becomes available, followed by the remaining loss tests.
At-risk limitationWhether the amount at risk supports the loss and other restrictions are satisfied.
Passive-activity limitationWhether qualifying passive income or a qualifying disposition permits use of the suspended amount.
Excess-business-loss limitationHow the resulting NOL carryover can be used under the applicable NOL rules.

The rules for these records are addressed in IRS Publication 541, the Form 6198 instructions, the Form 8582 instructions, and the Form 461 instructions.

For passive losses, a qualifying complete, fully taxable disposition to an unrelated buyer can allow suspended losses to be used. That does not mean every transfer releases every category of suspended loss. The transaction and each applicable limitation need review. IRS Publication 925

Keep the supporting schedules when changing tax preparers. The current K-1 alone may not show the investor-level history needed to apply these rules correctly.

What your CPA needs before estimating the deduction

Give your preparer enough information to connect the program's tax illustration with your own records:

  • The ownership and offering documents identifying the interest, entity, liability provisions, and funding obligations.
  • Your contribution and distribution history, current basis schedule, and prior suspended-loss schedules.
  • Borrowing documents and any guarantees or arrangements that could affect the amount at risk.
  • Current K-1 information and supporting statements, or the reporting appropriate to the structure.
  • Information about other business activities, qualifying passive income, and expected income for the year.
  • Relevant state information and the assumptions behind the program's deduction estimate.

Before investing, ask your CPA to separate the expected allocation into amounts projected to be usable now and amounts that could be deferred. For each deferred amount, identify the rule involved and the records needed for future years.

After final reporting arrives, reconcile the estimate with the actual figures. BassEXP's K-1 reporting guide provides additional context for that discussion.

Frequently asked questions

Does a loss on my K-1 guarantee a current deduction?

No. It reports an allocated item. Your preparer still applies the investor-level limitations and considers the rest of your return.

Can two investors in the same DPP receive different tax benefits?

Yes. Their allocations may be similar while their basis, financing, other income, prior losses, or remaining limitations differ. That can change the amount and timing of the deduction.

Does investing with cash eliminate the loss limitations?

Cash funding does not bypass the full sequence. Your ownership structure, other tax items, and applicable loss rules still matter.

Is a suspended deduction permanently lost?

It may become usable later, depending on why it was suspended and what happens afterward. Keep the separate schedules and review them before a sale, transfer, or other change in the investment.
