According to Official Letter No. 2800/BNI-QLDN1 issued by the Bac Ninh Provincial Tax Authority on 20 March 2026, from the 2025 corporate income tax (CIT) period onward, the consolidation of tax periods into the subsequent year will no longer be permitted.
This applies to cases where the first tax period of newly established enterprises (from the date of issuance of the Enterprise Registration Certificate or Investment Registration Certificate) or the final tax period of enterprises undergoing restructuring (including conversion of enterprise type or ownership, consolidation, merger, division, separation, dissolution, or bankruptcy) is shorter than 3 months. Previously, such short tax periods could be combined with the subsequent tax period to form a single CIT period under Clause 3, Article 3 of Circular No. 78/2014/TT-BTC.
Accordingly, enterprises newly established in 2025, as well as enterprises undergoing restructuring with a tax period of less than three months, are no longer allowed to consolidate the 2025 CIT period with the subsequent tax period to form a single CIT period.
