Mineral rights in Indiana can be owned separately from the surface of the land, which means the person who farms, builds on, or lives on a property is not necessarily the person who owns the oil, gas, coal, or stone beneath it. That separation, called a split estate, is the reason this area of law has its own rules for deeds, leases, taxes, and the quiet loss of rights that have gone unused for too long.
How You Come to Own Mineral Rights
Indiana Code Title 32, Article 23 governs transfers of property interests smaller than fee simple, including mineral interests carved out of a larger tract.1Indiana General Assembly. 2025 Indiana Code – Title 32, Article 23 A mineral deed is the instrument that performs the split, giving its holder the right to explore for and extract subsurface resources.
Three paths lead to ownership: buying the minerals directly, inheriting them, or reserving them when you sell the surface. Reservation is how most split estates begin. A seller conveys the surface but keeps the minerals through specific language in the deed, and once that reservation is recorded, it rides with the land through every later sale until the two interests are reunited.
Mineral deeds are recorded at the county recorder’s office. The county auditor must first stamp the deed “Duly Entered for Taxation,” and the document must carry a physical address for the new owner. An unrecorded transfer is still valid between the parties who signed it, but it leaves the holder exposed to competing claims from anyone without notice of the deal. Unrecorded mineral transfers are a leading source of title problems in Indiana.
The 20-Year Rule That Can Erase Your Rights
If you inherited mineral rights years ago and have never done anything with them, this is the section to read first. Under IC 32-23-10-2, a mineral interest in coal, oil, gas, or other minerals that goes unused for 20 consecutive years is automatically extinguished, and ownership reverts to whoever owns the interest it was originally carved out of, usually the surface owner.2Indiana General Assembly. Indiana Code 32-23-10-2 – Statement of Claims; Filing; Reversion
“Use” is defined broadly, so keeping an interest alive is not hard once you know what counts:
- Minerals are actually produced, or the site is used for injection, withdrawal, storage, or disposal operations.
- Rentals or royalties are paid for delaying or exercising the mineral rights.
- Production occurs on a tract the interest has been pooled or unitized with.
- For coal and other solid minerals, production occurs from a common vein or seam by the interest’s owner.
- The owner pays taxes on the mineral interest.
When none of those things has happened, the backstop is filing a statement of claim with the county recorder before the 20-year window closes.3Indiana General Assembly. Indiana Code Title 32 Property 32-23-10-3 – Presumption of Use Miss both the use requirement and the filing, and the interest is gone by operation of law. Heirs who may not even realize they hold severed mineral rights are the people most often caught by this rule.
Checking Title Before You Buy or Lease
A thorough title search is the single most important step before buying mineral rights or signing a lease on your own. Prior owners may have reserved minerals, sold them off separately, or encumbered them with liens, and none of that will show up on a casual look at the surface deed. Indiana’s long coal and oil history means some mineral chains stretch back more than a century with several severances along the way.
For meaningful transactions, buyers and lessees usually hire an attorney to prepare a mineral title opinion. The opinion traces ownership, identifies who currently holds valid interests, flags defects like unreleased mortgages, and sets out curative steps to resolve problems before money moves. A typical opinion includes a property description, an ownership summary by tract, a schedule of existing leases and liens, and a curative section calling out specific items such as unsatisfied judgments or tax delinquencies that need to be cleared before royalties can safely be paid.
Indiana courts have repeatedly stressed the importance of precise wording in mineral deeds and reservations. Vague language about which minerals are included, what depths are covered, and what rights the holder actually has is one of the most common triggers for litigation. Getting the deed right the first time is far cheaper than sorting it out in court later.
Leasing Your Mineral Rights
A mineral lease gives an operator the right to explore for and extract resources from your land for a defined period. Most leases run in two phases: a primary term, during which the operator has to begin operations or lose the lease, and a secondary term that continues as long as production does. The money usually arrives in two forms, a signing bonus paid upfront and royalties calculated as a percentage of what gets produced.
Royalty rates in Indiana are negotiable. They vary with the resource, the operator’s confidence in the site, and the landowner’s position at the table. Indiana does not set a statutory minimum, so what you agree to is what you get. Lease talks also cover operational details: which minerals the operator can target, where equipment may sit, and what condition the surface must be left in when operations end.
Delay Rentals and Shut-In Clauses
Two provisions trip up landowners more than any others. Delay rentals are annual payments an operator makes to hold the lease during the primary term without drilling. They keep the lease alive, but they are usually modest next to actual royalties. If the lease requires no delay rentals and the operator never drills, the lease simply ends when the primary term runs out.
Shut-in royalty clauses apply when a well can produce but is not being operated, often because of low prices or pipeline problems. The clause lets the operator keep the lease alive by paying a specified annual amount instead of producing. Without one, a non-producing well in the secondary term would usually cause the lease to lapse. Look closely at how long a well can stay shut in and whether the payment is large enough to justify tying up the land.
What to Negotiate Hard
Hiring an attorney who handles oil and gas leases is worth the cost, especially the first time. Key terms to push on include surface damage compensation, a royalty calculated on gross production rather than a net-back formula that lets the operator subtract its own expenses, and a Pugh clause so a single producing well cannot hold non-producing acreage under the same lease. Operators present a standard form that favors their position. Nearly every line is negotiable.
Taxes on Mineral Income
Indiana Severance Tax
Indiana imposes a severance tax on oil and natural gas, but not on coal or other solid minerals. The rate is the greater of 1% of the petroleum’s value or a flat per-unit amount: $0.24 per barrel of oil and $0.03 per thousand cubic feet of natural gas. The tax is imposed at the time of severance and falls on producers and owners.4Indiana General Assembly. Indiana Code 6-8-1-8 – Rate of Taxation Compared with major oil-producing states, Indiana’s rate is low.
Income Tax on Royalties
Royalty income is taxable at both the federal and state level. Indiana’s flat individual income tax rate is 2.95% for 2026, and county income taxes apply on top of that. Nonresidents who receive royalties from Indiana mineral interests must allocate that income to Indiana and file a nonresident return.5Indiana Department of Revenue. Income Tax Information Bulletin 39 – Guidelines for Reporting Income from Indiana Sources by Nonresident Individuals Out-of-state heirs who inherit Indiana minerals and never think about state tax are the ones most often caught by this requirement.
Federal Percentage Depletion
At the federal level, mineral owners can often reduce taxable income through the percentage depletion allowance, which lets you deduct a fixed percentage of gross mineral income without tracking your actual basis. Rates vary by mineral: 15% for oil and gas (for qualifying independent producers and royalty owners), 10% for coal, 5% for sand and gravel, and up to 22% for certain metals and other minerals.6Office of the Law Revision Counsel. 26 USC 613 – Percentage Depletion For oil and gas, the deduction is limited to production from up to 1,000 barrels per day and cannot exceed 65% of your taxable income from all sources.7Office of the Law Revision Counsel. 26 USC 613A – Limitations on Percentage Depletion in Case of Oil and Gas Wells A tax professional who works with extractive industries can help you claim it correctly.
Common Disputes
Most mineral litigation in Indiana follows a few patterns. Ambiguous deed language is the most frequent trigger. When a decades-old deed reserves “oil and gas” and the modern dispute involves coalbed methane, courts have to decide what the original grantor intended for a substance that was not commercially viable at the time. Indiana courts apply standard contract interpretation, looking first to the four corners of the deed and only turning to extrinsic evidence when the language is genuinely ambiguous.
Royalty disputes are the second big category. Operators sometimes underreport production, deduct unauthorized post-production costs, or sell to affiliates at prices that do not reflect the market. Suspected underpayment may require forensic accounting to reconstruct what was produced and what is owed. Lease wording decides the outcome: a royalty on “gross proceeds at the wellhead” produces a very different number than one on “net proceeds after transportation and processing.”
Surface damage claims round out the picture. When a mineral owner or lessee damages crops, roads, fences, or water supplies during operations, the surface owner may have a claim. Indiana has no dedicated surface owner protection statute, so these disputes are generally resolved through common law reasonable-use principles and whatever the lease itself says. If you are negotiating a new lease, insist on a surface damage clause that spells out what the operator must pay for and how the land must be restored.
Permits and Regulation (For Operators)
If you are a landowner rather than an operator, most of Indiana’s permitting system sits on the other side of the table. The Indiana Department of Natural Resources oversees extraction through its Oil and Gas Division and Division of Reclamation.8Indiana Department of Natural Resources. DNR: Oil and Gas Home Operators must obtain permits before drilling or mining, post bonds, and comply with reclamation requirements under IC 14-36-1-1, which directs that mined land be restored to protect water, reduce erosion and fire hazards, improve the landscape, and support wildlife habitat.9Indiana General Assembly. Indiana Code 14-36-1-1 – Purpose of Reclamation For a landowner, the practical point is that the permitting process includes public hearings, which give you a chance to raise concerns about a proposed site near your property before a permit is issued.
