The Oil and Gas Depletion Deduction, Explained
If you receive royalty income from an oil or gas well, the IRS lets you shelter part of that income from tax each year through a provision called depletion. It works much like depreciation does for a building, recognizing that the resource being produced is a finite asset that is literally running out over time. Many royalty owners never claim it simply because they do not know it exists, which can mean paying more tax than necessary.
What Depletion Means
Oil and gas are nonrenewable resources, so every barrel or cubic foot of gas pulled from the ground permanently reduces the value of the reserve left behind. Depletion is the tax code's way of letting an owner recover that lost value over the life of the well, similar to how a business writes off equipment as it wears down. There are two methods available, cost depletion and percentage depletion, and most individual royalty owners end up using whichever one produces the larger deduction in a given year.
Cost depletion ties the deduction to what the owner originally paid for the mineral interest, divided across the estimated recoverable reserves and applied as those reserves are produced. It requires an engineering estimate of total reserves and careful recordkeeping, which is part of why many smaller royalty owners lean toward the simpler percentage method instead. Either way, the goal is the same: matching the deduction to the gradual loss of a resource that cannot be replaced once it is produced.
How Percentage Depletion Works
Percentage depletion is the method most royalty owners use because it does not require tracking the original cost basis of the mineral interest. Instead, it allows a deduction equal to a set percentage, generally 15 percent, of the gross income the property produces, regardless of how much the owner originally paid for the rights. Unlike cost depletion, percentage depletion can sometimes continue even after the owner has fully recovered their investment, within limits set by law. The deduction is also capped at a percentage of the property's taxable income for the year, so it will not create a loss on its own.
Who Should Pay Attention
This deduction is generally available to independent producers and royalty owners rather than large integrated oil companies, and it applies whether the interest came from a direct lease, an inheritance, or a purchase. Because depletion rules involve income limits, barrel and cubic foot thresholds, and interactions with other deductions, the right approach depends on each owner's full tax picture. A CPA familiar with oil and gas income can confirm which method applies and whether percentage depletion continues to make sense from year to year.
Owners who are new to receiving royalty payments, or who have never reviewed their depletion deduction with a tax professional, may be leaving money on the table each filing season.
