Handling tax declarations for the first quarter of 2026 for 3 specific cases
According to Decree 141/2026/ND-CP, households and individual businesses with revenue of 1 billion VND/year or less are not subject to tax. Quarterly declaration only applies to cases over 1 billion VND. However, at the intersection of the first quarter of 2026, business households need to pay attention to 3 scenarios:
Case 1: Not yet submitted tax return for the first quarter of 2026 Business households only need to track revenue through books. If the whole year does not exceed 1 billion VND, send a notice that revenue is not subject to tax no later than January 31, 2027. If exceeding the threshold occurs in the year, it must be declared immediately in that quarter.
Case 2: Declaration has been submitted but tax has not been paid Taxpayers may temporarily not pay money and adjust revenue to 0 to avoid arising overpaid tax obligations, and at the same time keep the registered account information.
Case 3: Both declaration and tax money have been submitted to the budget. Implement tax refund procedures according to Article 12 of Decree 141/2026/ND-CP if the revenue for the whole year is less than 1 billion VND. If at the end of the year it exceeds the threshold, the amount paid will be offset in subsequent periods.
Mandatory notification of bank accounts related to business
Based on Clause 4, Article 13 of Decree 68/2026/ND-CP, business households must notify electronically all bank account numbers and electronic wallets related to production and business activities.
This regulation helps tax authorities to make cash flow transparent and control revenue. However, personal accounts serving living expenses, not used for business purposes, are not required to be declared.
