Revenue Information Bulletin No. 26-013
June 2, 2026  Severance Tax
Natural Gas Severance Tax Rate Effective July 1, 2026, through June 30, 2027
The natural gas severance tax rate effective July 1, 2026, through June 30, 2027, has been set
at 15.14 cents per thousand cubic feet (MCF) measured at a base pressure of 15.025 pounds
per square inch absolute and at the temperature base of 60 degrees Fahrenheit.
This tax rate is set each year by multiplying the natural gas severance tax base rate of 7 cents
per MCF by the “gas base rate adjustment” determined by the Secretary of the Department
of Conservation and Energy in accordance with La. R.S. 47:633(A)(5)(d)(i). The “gas base
rate adjustment” is a fraction, of which the numerator is the average of the New York
Mercantile Exchange (NYMEX) Henry Hub settled price on the last trading day for the month,
as reported in the Wall Street Journal for the previous 12-month period ending on March 31,
and the denominator is the average of the monthly average spot market prices of gas fuels
delivered into the pipelines in Louisiana as reported by the Natural Gas Clearing House for
the 12-month period ending March 31, 1990 (1.7446 $/MMBTU).
Based on this computation, the Secretary of the Department of Conservation and Energy has
determined the natural gas severance “gas base rate adjustment” for April 1, 2025, through
March 31, 2026, to be 2.163. Applying this gas base rate adjustment to the base tax rate of 7
cents per MCF produces a tax rate of 15.14 cents per MCF effective July 1, 2026, through June
30, 2027. The reduced natural gas severance tax rates provided for in La. R.S.
47:633(A)(5)(b) and (c) remain the same at 3 cents per MCF and one and three-tenths cent,
respectively.
Gas produced from an inactive or orphan gas well is subject to a reduced severance tax rate
equal to twenty-five percent (25%) or twelve and one-half percent (12.5%) of the severance
tax rate, respectively, as provided in La. R.S. 47:633(A)(3)(c)(iii). Therefore, the inactive gas
reduced tax rate is 3.785 cents per MCF, and the orphan gas reduced tax rate is 1.8925 cents
per MCF effective July 1, 2026, through June 30, 2027.
