Abstract

As commercial space activities move from state-led exploration to market operations, outer space is changing from a mission space into a workspace. As a result, the traditional connecting point for employment taxes, centered on the workplace, begins to lose force. This Article develops the concept of outer space employment taxation and argues that its key issue is not taxation in orbit, but enforceability. International space law does not directly provide the tax base, tax rates, or specific withholding rules. But through state responsibility, authorization and continuing supervision, and registration coupled with jurisdiction and control, it already provides institutional interfaces through which employment taxes may be embedded in commercial space activities. On that basis, this Article builds a matrix of connecting points in three categories: actor connecting points, procedural connecting points, and money and information connecting points. It argues that withholding, reporting, auditing, and remedies should be anchored to controllable terrestrial nodes, including licensing, registration, launch and return, ground control, and payroll settlement. Using the United States and China as comparative cases, this Article further argues that whether outer space employment tax can become institutionally collectible depends on a single withholding agent, front loaded standardization of necessary information, and procedural coordination for duplicate burdens.
