Selling Mineral Rights: How to Defer Capital Gains Tax

By Sean Whitehead, Structured Settlement Consultant & Content Contributor · November 3, 2026 · 7 min read

Selling mineral rights means selling the mineral estate: oil, gas, coal, and other minerals, owned with the surface or inherited after a severance. The capital gains tax on selling mineral rights falls on that sale. A lease bonus and a royalty are ordinary income. How to defer taxes on a sale of mineral rights, when a sale fits, is the installment method under IRC §453. Recapture, and deeds taxed as a lease, are in selling mineral rights: capital gains, recapture, and the installment sale. Ranch minerals are in selling a ranch in Texas.

Current figures

What you own

A mineral deed conveys oil, gas, and other minerals, or it reserves some formations. Many owners hold an undivided fraction. In the main producing states the estate is real property and can sit apart from the surface. A lease leaves you the owner: a bonus, a royalty, and a reversion when the lease ends. Unleased minerals pay no royalty. Leased minerals may be producing, held by production, or still in a primary term. A carved-out royalty is a smaller interest than this estate.

How buyers value mineral rights

On producing minerals, buyers read the lease, the royalty fraction, outstanding burdens, title, and depth rights, then apply their own view of remaining production and prices. On unleased minerals they look at net mineral acres, location, and title. A bid is not date-of-death value, and it is not your tax basis.

Capital gain, a lease bonus, and royalty income

A lease bonus is ordinary income, and you still own the minerals. Royalties are ordinary income each year. Depletion offsets part of them. A sale held more than one year is long-term capital gain. Held one year or less, it is short-term, taxed at ordinary rates. Count from the day after acquisition through the sale date. Publication 544 treats inherited property as held more than one year, including a sale within a year of the death. Section 453 spreads gain on a sale. A bonus and a royalty are reported when received.

Basis, a step-up, and depletion

Gain is amount realized minus adjusted basis. Purchased minerals start at cost. Inherited minerals take fair market value at death, or the alternate valuation date if the estate elects it, under section 1014. Publication 551 covers basis. The prior owner's depletion does not carry into that new basis.

Later depletion that was allowed or allowable reduces basis, and basis does not go below zero. Cost depletion reduces it. So does percentage depletion taken while basis remained. Percentage depletion after basis is already zero does not. A lower basis means more gain on a sale. Section 1254 can make part of that gain ordinary in the year of sale. That part is recognized up front. The capital remainder can be spread. The recapture article and your preparer cover the amount.

Federal rates and the 3.8% tax

Long-term gain stacks on taxable income at the 0%, 15%, and 20% lines in the box. The excess over the 15% line is taxed at 20% in the year it is recognized. The 3.8% tax reaches royalties and, for a passive owner, gain on the minerals. A working interest in which you materially participate can fall outside it. Installment interest is generally included. See the Form 8960 instructions and section 1411.

State tax follows the minerals

Federal character is the same in every state. State income tax is not. Texas does not tax an individual's gain. Oklahoma, North Dakota, West Virginia, and Pennsylvania each have their own rules, and Pennsylvania uses its own installment election. Living in one state while the minerals sit in another can mean two returns. Start with capital gains tax by state, then the guide for the state where the minerals are.

Five ways to handle the minerals

Keep them and collect royalties

You remain the owner. Producing royalties are ordinary income, partly offset by depletion, and they move with price and decline. Unleased acres can pay nothing for years. Holding until death can give heirs a new section 1014 basis, which often fits when basis is close to value. Sell or hold is that choice. An installment still open at death is income in respect of a decedent under section 691, so that step-up does not erase gain not yet recognized.

Sell for a lump sum

Closing pays the price and recognizes the gain that year. You are done with division orders and with price risk. A large gain can reach the 20% rate and the 3.8% tax in that one year, plus state tax where it applies.

Sell a portion

An undivided fraction is a sale of that fraction. The part sold can be long-term gain. The part kept still pays ordinary royalties, and it can still take a step-up if you hold it until death. A term of years or a retained production payment can be taxed as a lease. The companion article draws that line. Have the preparer read the deed first.

Exchange them under section 1031

Section 1031 defers gain on real property held for investment or business use. The regulations include unsevered natural products of land and interests state law calls real property. In the major producing states a mineral estate can be exchanged for other minerals or a rental property. Confirm that label where the minerals sit. You need a qualified intermediary, 45 days to identify, and 180 days to close, and you have to want the replacement. Signing a lease is not an exchange. When the goal is to keep owning real estate, a 1031 defers gain an installment sale would recognize. See the 1031 comparison and the farmland version.

Use a structured installment sale

The contract needs at least one payment after the year of sale, signed before you can demand the cash. The buyer pays the deferred price at closing to an assignment company. You do not take that money then. Each Form 6252 payment is return of basis, capital gain, and ordinary interest, using the gross profit percentage in Publication 537. The gain is taxed as payments are received, which can change the bracket and the 3.8% result. What a structured installment sale is and the §453 guide show the steps.

Ordinary recapture stays in the year of sale. A related buyer's resale within two years can accelerate gain under section 453(e), and section 453(g) can block installment treatment of depreciable property sold to a related person. Large notes can carry additional rules; review them with your CPA. Seller financing leaves the buyer owing the payments. That comparison and the risks page cover who owes the schedule. A deferred sales trust uses different documents, set out in the trust comparison.

Hypothetical example

A married couple files jointly. Inherited basis is $400,000. They sell for $1,600,000, expenses ignored, so long-term gain is $1,200,000. Other income is $95,000. A lump sum recognizes that gain in one year, reaches the 20% rate, and puts modified adjusted gross income over the 3.8% threshold. Ten principal payments of $160,000 treat $120,000 of each as gain, and each slice stays below the 20% line in the box. Interest is left out. Adding it can move a year across the 3.8% threshold. The calculator does not model depletion or a second state.

Bring the return preparer in before the purchase agreement is signed. Basis, the lease, the deed, and the payment schedule are all harder to fix after closing. We will model the payment side with both of you, and say so when holding, a partial sale, or a 1031 exchange fits the minerals better.
