Senate panel reviews oil tax floor increase projecting $132M annual gain

The Alaska Senate Resources Committee on Monday reviewed Department of Revenue modeling showing that increasing the state's minimum oil production tax floor from 4% to 6% would generate an average of $132 million in additional annual revenue over the next decade, though the analysis revealed complex interactions with existing tax provisions that could reduce revenue in certain years, according to the department's presentation.

The committee first adopted a committee substitute, Version S, as its working document before hearing the modeling presentation, which was one of several analyses requested from the Department of Revenue, mostly received the previous Wednesday.

The analysis, presented by Owen Stevens, a commercial analyst with the Department of Revenue's Tax Division, projected the higher floor would increase state revenue in most years between fiscal year 2027 and fiscal year 2036, peaking at $199 million in 2033. The modeling showed a negative revenue impact of $50 million in fiscal year 2034, reflecting how the increased floor would affect companies' ability to apply carryforward lease expenditures and interact with per-barrel tax credits.

Alaska's oil production tax has been the subject of repeated legislative revision since the state replaced Alaska's Clear and Equitable Share system with the More Alaska Production Act in 2013. The current system calculates tax as the greater of a 35% net tax or an applicable minimum tax floor, which stands at 4% of gross value at the point of production when North Slope oil prices exceed $25 per barrel. The Alaska Legislature has considered multiple bills in recent years to adjust per-barrel credits, corporate income tax treatment, and minimum tax floors for oil producers, with the Senate Rules Committee introducing Senate Bill 114 in March 2023 to raise corporate income tax rates and reduce per-barrel credits.

Stevens cautioned that the production tax system is very complex, with multiple interacting provisions, and that the numbers were based on a preliminary interpretation of bill provisions. "Many of the provisions here would need to be addressed through regulations," Stevens said. "I'm an economist, not an auditor."

The department modeled the increased floor in two ways: first by examining impacts on the spring 2026 revenue forecast for existing North Slope production, and second by analyzing how the change would affect revenue from a potential Alaska LNG project. Stevens noted that the two models were "not necessarily directly joined to each other" and that a full company-by-company integration could potentially change results to some extent, though directionally the numbers should be reasonable.

The combined modeling showed total revenue impacts ranging from negative $50 million to positive $243 million depending on the year, with the variation driven by how companies would apply lease expenditures under different minimum tax scenarios.
