VAT returns in Istanbul move to the new e-Beyan system
According to the Revenue Administration’s announcement of 14 October 2026, VAT returns in Istanbul are filed on the new e-Beyan system from the October 2026 period.
According to the Revenue Administration’s announcement of 14 October 2026, KDV1, KDV2, KDV2B, KDV4 and KDV9015 returns were already filed on the new e-Beyan system in all provinces except Istanbul. From 1 November 2026, starting with the October 2026 period, these returns will also be filed on e-Beyan in Istanbul.
What does not change
- Original and corrective returns for periods before October 2026 continue on the e-Beyanname (BDP) system.
- Filing and payment deadlines are the same: the 28th of the following month, or the first working day if it is a holiday.
