The Vermont House Committee on Ways and Means is actively exploring a proposal to become the first state to enact mandatory worldwide combined reporting for corporate income tax purposes. While legislation has not been formally proposed, the Committee has examined a working draft that could be embedded into a broader tax legislation package.

In Committee testimony supporting the adoption of mandatory worldwide combined reporting, Don Griswold, a senior fellow at the Center on Budget and Policy Priorities, argued that multinational corporations “pay huge fees to sophisticated advisers to develop an endless variety of complex schemes that shift their profits offshore.” According to him, mandatory worldwide combined reporting would be “the complete solution” to stopping what he perceives as a “loophole for massive tax avoidance.” He also intimated that several companies are among those he believes are currently engaging in “tax avoidance,” even though he freely acknowledged that he worked in a “Big 4 accounting firm’s 600-person ‘state tax minimization’ group” for most of his career.

On the other hand, at least one representative from the Vermont Department of Taxes has suggested that worldwide mandatory combined reporting is not the panacea that Griswold claims it would be. In Committee testimony, Will Baker, assistant attorney general and general counsel at the Department of Taxes, pointed out that a corporation’s Vermont taxable income could increase or decrease under worldwide combined reporting depending on the profitability of the corporation’s domestic and overseas subsidiaries and the locations of the corporate unitary group’s sales throughout the world. Baker also suggested that the Department of Taxes would face practical challenges calculating the income of subsidiaries that are not part of a corporate filing at the US federal level. Finally, he added that “small states” should generally “have the same rules that other states have” to make it easier for taxpayers to comply with Vermont law.
