If you want to voluntarily repay student financial aid for 2022, you must do this before the end of April. Students can check the preliminary information on the annual income that will be taken into account for the purposes of student financial aid in the OmaKela e-service. On the basis of the preliminary information, students can determine whether they will have to repay financial aid. If the student does not repay the overpaid financial aid by the end of April, Kela will recover the overpaid amount increased by 7.5%.
