Model Receipts Sourcing Regulation Review Work Group

At its August 2022 meeting, the Uniformity Committee agreed to undertake a project and form a work group to review its model receipts (sales) sourcing regulations for income apportionment purposes, including special industry regulations and more recently adopted market-based sourcing regulations. The goal of this project is to identify updates, corrections, or conforming changes, to consider issues that may not be sufficiently addressed by existing model regulations, and to make recommendations to the committee for its action.

Sales Tax on Digital Products Work Group

At its July 2021 meeting, the Uniformity Committee considered a recommendation from the Standing Subcommittee to begin drafting  a white paper on state sales taxation of digital products and the approaches that states might use. The committee asked MTC staff to begin the process by getting input from stakeholders and doing other research. Based on this work, staff prepared a draft outline of the white paper and presented it to the committe in November, 2021. The committee agreed to form a work group discuss the issues identified in that outline as well as any other related issues.
