The University of Siena publishes the regulations on student fees on an annual basis.
Students enrolled on first cycle, second cycle and long single cycle degree programmes pay four instalments of tuition fees.
The amount each student pays is based both on his/her family income, as declared in the ISEE certification, and on merit.

The tax regulations, including indications about the income ranges, the amount of the fees, the calculation methods and the deadlines for payments, are published annually.
