Severance Tax

Severance tax is a state-level tax assessed on the volume or value of oil and gas extracted from the ground. It is one of the post-production deductions that can reduce a mineral owner’s royalty payment, and it is reported on most royalty statements as a separate line item.

Each producing state sets its own severance tax structure, and the rates vary significantly. Texas charges 4.6 percent on oil and 7.5 percent on natural gas. Wyoming charges 6 percent on oil and gas. North Dakota uses a tiered structure where the rate depends on price and production stage. Oklahoma charges 7 percent on most production. Pennsylvania uses an “impact fee” rather than a true severance tax. Each state’s rules include exemptions, incentives, and special categories (stripper wells, enhanced recovery, etc.) that complicate the headline rate.

For royalty owners, severance tax is typically deducted from the gross royalty value before the owner’s check is calculated. The royalty statement will show: gross royalty value, less severance tax, less other deductions, equals net royalty paid. This is true in most states, though specific lease language can shift the burden between mineral owner and operator.

A few practical implications:

State severance tax revenue is one of the largest single revenue sources for several producing states. Wyoming, North Dakota, and Alaska in particular fund significant portions of their state budgets from severance taxes. Mineral owners are funding state services indirectly through these taxes on their royalty income.

Severance tax is separate from federal income tax. It is a state production tax, paid by the operator as the producer of record, but ultimately borne by the working interest and royalty owners through reduced net revenue. Federal income tax is paid separately on the post-severance-tax royalty payment.

Some states allow severance tax to be deducted as a state tax on the federal return, though the rules are complex and vary by individual situation. A CPA with oil and gas experience handles this in the tax preparation process.

Severance tax cannot be avoided through ownership structures or trusts. It is a tax on the production itself, paid by the operator, regardless of who owns the underlying interest. This is one of the few areas of mineral ownership where there is no clever structuring to reduce the burden.

For inheritors comparing royalty statements across states, severance tax is one of the explanations for why the same gross royalty rate can produce meaningfully different net payments. A 1/4 royalty in Pennsylvania (no severance tax, but an impact fee) produces a different net per-barrel result than the same 1/4 royalty in Wyoming (6 percent severance tax). Neither is better or worse, but the difference is real.
