In a judgment delivered on November 30, 2021, the Supreme Court examines whether it is allowed to offset tax losses on a corporate income tax self-assessment filed outside the time limit and concludes that it is. Moreover, according to a judgment on October 29, 2021 by the National Appellate Court, if this gives rise to an incorrect payment, the incorrectly paid tax must be refunded with late-payment interest calculated from when that payment was made (including prepayments).
