About two thirds of the ITA's work is financed by the Federal Ministry of Education, Science and Research through the budget of the Austrian Academy of Science; currently one third stems from third-party funds. The latter sources are either competitive grants, for instance from the European Union or various research funds, or are studies on contract for institutions such as the Austrian Council for Research and Technology Development (RFTE), the Federal Ministry of Transport, Innovation and Technology (BMVIT) or the Science and Technology Options Assessment (STOA) panel of the European Parliament.

The general study conditions "Allgemeinen Studien-Bedingungen" (german language only) of the ITA contain further details on funding and project management.
