Background
Equinor USA Onshore Properties Inc., a natural gas producer in West Virginia, pays a five percent severance tax on the “gross value” of natural gas it produces. The company sells its raw gas to MarkWest Liberty Midstream & Resources LLC, which processes and fractionates it into natural gas liquids (NGLs) under a contractual arrangement. MarkWest then sells the NGLs to third parties and pays Equinor the net proceeds after deducting various fees and charges for fractionation, pipeline transportation, marketing, and loading.
Equinor filed amended severance tax returns for tax years 2014, 2015, 2016, 2018, and 2019, seeking refunds based on a recalculation of the gross value using the net amount it actually received from MarkWest. The Tax Commissioner decreased these refunds, arguing that the taxable value should be the full product value that MarkWest received from selling the NGLs to third parties—a much higher figure. The dispute also included a timeliness question: whether Equinor’s 2020 petition to challenge the tax year 2015 refund decision was filed within the sixty-day statutory deadline.
The Court’s Holding
The court affirmed the Intermediate Court of Appeals’ reversal of the tax authority’s decisions on the substantive tax issue. The Supreme Court held that under West Virginia’s severance tax statute, “gross proceeds” means the actual value received by the producer from the sale, not the value received by the processing company. Because Equinor transferred title to its raw make to MarkWest at the point where MarkWest received it (before processing), the only sale to which Equinor was a party was the sale to MarkWest. Therefore, the net value Equinor actually received—not the product value MarkWest later received from third parties—represents the correct “gross proceeds” for tax calculation purposes. This means Equinor was entitled to deduct its actual transportation and transmission costs or claim the statutory fifteen percent safe harbor deduction.
On the timeliness issue, the court reversed the intermediate appellate court. The court held that Equinor’s April 2020 petition to the Office of Tax Appeals regarding tax year 2015 was timely filed. The court focused on West Virginia Code § 11-13A-9(b) and concluded that because the Tax Commissioner’s office was still reviewing the calculation in February 2020 (and even issued an additional refund check), Equinor reasonably relied on assurances that a revised determination letter would be issued, making the April filing date timely under the statute.
Key Takeaways
- The “gross proceeds” for severance tax purposes equals the actual money the producer receives, not amounts received by downstream processing companies—even if those amounts are larger.
- Processing activities like fractionation are excluded from the definition of “severing” under the statute, so value added through processing cannot be attributed to the producer for tax purposes.
- Producers may deduct actual transportation and transmission costs or elect a fifteen percent safe harbor deduction, but cannot be denied both options simply because they seek refunds based on recalculated gross proceeds.
- Equitable estoppel cannot override statutory filing deadlines with tax agencies, but taxpayers may have timely filed if the agency was still actively reviewing and revising its determination.
Why It Matters
This decision significantly impacts how natural gas producers calculate severance tax obligations in West Virginia, particularly when their gas is processed by third parties. By clarifying that only amounts actually received by the producer count as “gross proceeds,” the court rejected an interpretation that would have taxed value created entirely by a processing contractor’s downstream activities. This aligns the statute with its plain language and legislative intent to tax the producer only on its actual proceeds.
The ruling potentially opens the door to substantial refund claims across the industry and establishes that producers need not choose between claiming actual costs and the safe harbor—they can deduct their true costs from the correct baseline (net proceeds). For tax compliance and refund planning, natural gas producers must now carefully track settlement statements to identify the net value actually received, not merely the product values shown by processing contractors.
