If you own mineral rights and receive royalty checks, a portion of your money is being withheld before you ever see it. That deduction is called a severance tax — a tax that states charge on oil, natural gas, and other minerals at the moment they're "severed" from the ground. It's not a scam, it's not an error on your check, and it's not negotiable. It's built into state law, and it varies significantly depending on where your minerals are located.
By the time you finish reading this, you'll know what severance tax is, what your state's rate looks like, how it gets deducted from your royalties, and what that means for the actual value of the income your minerals produce. If you're thinking about selling your mineral rights, understanding severance tax is one of the key factors in knowing what those rights are actually worth.
What Severance Tax Is and How It Comes Out of Your Check
When an oil or gas company produces minerals from your land, they don't pay you your full royalty share and then let you handle the taxes on production separately. Instead, they withhold the severance tax on your behalf and send it to the state. You see the net amount — after the tax has already been taken out.
Here's a simple example. Say your royalty rate is 20%, the well produced oil worth $10,000 in a given month, and your state charges a 4.6% severance tax on oil. The operator calculates 20% of $10,000, which is your $2,000 gross royalty. Then they deduct 4.6% of that $2,000 — about $92 — and send it to the state. You receive $1,908. That $92 isn't coming back, and it's not a mistake.
The tax is based on the gross value of production, not your net income after expenses. That's an important distinction. Even if a well is barely profitable for the operator, the severance tax still applies at the same rate. It's a production tax, not a profits tax.
Most royalty owners don't realize how much severance tax accumulates over time. On a modest royalty producing $18,000 a year, a 4% severance tax quietly removes $720 annually. Over a decade, that's $7,200 — real money that reduces the total value of your mineral interest.
Severance Tax Rates by State: The Numbers You Need
Here's what you actually need to know about rates across the major oil and gas states. These are current rates as of the time of writing, but state legislatures can and do adjust them, so verify with your accountant or the state revenue department if you're making a major financial decision.
Texas charges a 4.6% severance tax on oil (called the "oil production tax") and 7.5% on natural gas. Texas is the largest oil-producing state in the country, and these rates apply across the board. On a $2,000 monthly oil royalty in Texas, you're losing about $92 to severance tax each month, or roughly $1,100 a year.
Oklahoma has a more complicated structure. The state uses a tiered system: new wells receive a reduced rate of 2% for the first 36 months of production, after which the standard rate of 7% kicks in. Oklahoma also charges 7% on natural gas. If you own royalties in Oklahoma and your well is still in that early-production window, your checks look better than they will three years from now — something to keep in mind when evaluating what those royalties are worth long-term.
Louisiana charges 12.5% on oil production and 12.5% on natural gas production — one of the higher rates in the country. However, Louisiana offers numerous exemptions and reduced rates for certain well types, including horizontal wells and wells in specific formations. A new horizontal well in Louisiana might qualify for a reduced rate for the first 24 months. The state's complexity means your actual effective rate could be lower, but you need to look at your check stubs carefully to see what's being withheld.
North Dakota charges 5% on oil extraction plus an additional 6.5% oil extraction tax, for a combined rate around 11.5% depending on the calculation method. North Dakota's Bakken formation has made it one of the top-producing states in the U.S., but that high combined rate means a meaningful portion of your royalty income is going to the state before it gets to you.
Pennsylvania does not have a traditional severance tax on oil and gas production. Instead, the state charges an impact fee — a flat per-well annual charge paid by the operator, not deducted from royalties. For mineral owners, this is actually favorable: your royalty check doesn't take a direct percentage hit from a production tax the way it would in Texas or Louisiana. The impact fee amount varies by well age and commodity prices but is paid entirely by the producer.
West Virginia charges 5% on oil and 5% on natural gas. It's a straightforward rate without many of the tiered structures you see in Oklahoma or Louisiana.
Colorado charges 2% on both oil and gas for the first 12 months of production, then steps up to 3% for the next 36 months, and ultimately settles at 5% once the well matures. If you own royalties in Colorado on a newer well, your current deduction looks lower than what you'll see a few years down the road.
Wyoming charges 6% on oil and gas production. Wyoming also has county-level taxes that can add to this, so your effective rate may be slightly higher than the state number suggests.
New Mexico charges 3.75% on oil and 7.09% on natural gas under its oil and gas severance tax structure, though the state also layers on additional production taxes that bring the combined burden higher — sometimes over 10% on oil when all components are included.
Montana charges between 9% and 14.8% on oil depending on the production rate of the well (lower-producing "stripper" wells get better rates), and about 14.8% on natural gas at standard rates. Montana's rate is among the highest for oil in the country.
Kansas charges 8% on oil and 8% on gas — a flat, relatively high rate without significant tiering.
Ohio has a severance tax, but it's very low — roughly $0.10 per barrel on oil and $0.025 per thousand cubic feet on gas for most production. Ohio's rate is effectively minimal for most mineral owners.
Utah charges 3% on the first $13 per barrel equivalent of value and 5% on amounts above that threshold for oil. Natural gas is taxed similarly on a tiered basis. Utah's structure is a bit more complex but generally lands in the 4–5% range for most production.
Mississippi charges 6% on oil and 6% on gas, with some exemptions for certain well types.
Alabama charges 8% on oil and 5% on gas as a general rule, though there are various incentive rates for specific situations.
Arkansas charges 5% on oil and 5% on gas, rising to 4% and 5% respectively after an initial reduced-rate period for new wells.
Alaska operates differently from the lower 48 states — its production tax system is complex and production-value-based rather than a simple percentage of gross value. For most Alaska mineral owners with royalty interests (rather than working interests), the practical impact is handled through the operator, but Alaska's overall tax burden on oil production is among the most significant in the country.
California charges a small "assessment" rather than a traditional severance tax — it's based on the value of production but runs well under 1%. California mineral owners are largely not affected by severance tax the way owners in Texas, Oklahoma, or Montana are.
How Severance Tax Affects the Value of Your Mineral Rights
If you're considering selling your mineral rights, you need to understand that severance tax doesn't just affect your monthly check — it affects what a buyer will pay you.
When a mineral rights buyer values your interest, they typically start with your current royalty income and project it forward. They'll apply what's called a discount rate to account for the fact that production declines over time and future money is worth less than present money. The clean, simple math runs on net royalty income — the amount after severance tax.
Here's where it matters. Two mineral owners each receive a gross royalty of $2,000 a month before taxes. One is in Pennsylvania (no direct severance tax on royalties), and the other is in Louisiana (12.5% severance tax). The Pennsylvania owner's net royalty is $2,000. The Louisiana owner's net royalty is $1,750. Over 12 months, that gap is $3,000. Over the projected life of a buyer's model — often 20 to 30 years — the difference compounds significantly.
In practice, buyers factor the applicable state severance tax into their valuation automatically. But as a seller, you should understand that high-severance-tax states like Montana, North Dakota, Louisiana, and Kansas produce mineral rights that are worth less on a per-dollar-of-gross-royalty basis than comparable interests in Pennsylvania, Ohio, or Texas. That's not a reason not to sell — it's just context for understanding the offer you receive.
Common Mistakes Mineral Owners Make With Severance Tax
The most common mistake is not knowing the deduction exists at all. Many inherited mineral owners receive royalty checks for years without ever reading the check stubs carefully enough to notice the line items. If you haven't looked at your actual check stub recently, do it before anything else. You'll typically see a line labeled "severance tax," "production tax," or something state-specific like "Oklahoma gross production tax." That number tells you what's leaving your royalty before it hits your account.
The second mistake is assuming the operator is withholding the right amount. Operators are generally accurate, but errors happen — particularly on royalties that span multiple formations, multiple counties, or that involve wells with special exemption status (like Oklahoma's 2% incentive rate for new wells). If your well is new and you're seeing 7% withheld for Oklahoma gross production tax instead of 2%, you may be owed money. It's worth asking.
The third mistake is not accounting for severance tax when reporting income. Severance tax withheld on your behalf is technically paid out of your share of production. Your 1099 from the operator will show gross royalties in some cases, and you'll need to account for the severance tax appropriately when filing. Talk to a CPA who handles oil and gas royalties — not just any tax preparer — because the rules vary by state and have quirks that general practitioners sometimes miss.
When You're Thinking About Selling: What Severance Tax Tells You
Severance tax is one of several factors that determine what your mineral rights are worth in the market right now. It's not the most important factor — production volume, commodity prices, well age, and acreage quality all matter more — but it's a real, permanent drag on royalty income that doesn't go away.
If you sell your mineral rights, you receive a lump-sum payment and severance tax is no longer your concern. The buyer assumes all future production costs, taxes, and risks. That's one of the genuine financial arguments for selling: you're converting a stream of income that's subject to ongoing taxes, production decline, price volatility, and operator decisions into a single, certain payment.
Whether that trade makes sense for your situation depends on your goals, your tax situation (selling mineral rights often triggers capital gains tax, which your CPA can help you think through), and whether the offer you receive fairly reflects the value of what you own.
One honest thing worth saying: mineral rights values are high right now in many basins, particularly in the Permian Basin in Texas, the SCOOP and STACK plays in Oklahoma, and several Appalachian formations in West Virginia and Pennsylvania. If you've been sitting on inherited minerals without paying much attention to them, the market has changed substantially in the last several years, and what they're worth today may surprise you.
