Nghị định số 68/2026/NĐ-CP, Điều 4 khoản 5; Luật Thuế TNCN số 99/2025/QH15, Điều 10 khoản 1
OverdueThe Dong Nai Tax Department advised: a household business that has been applying the flat-rate method (tax rate x revenue) since July 2025, with 2025 revenue above VND 3 billion but estimated 2026 revenue below VND 3 billion, must still apply the income-based PIT method (taxable income = revenue minus expenses) in 2026 - it cannot revert to the flat-rate method.
Under Decree 68/2026/ND-CP: household businesses with revenue of VND 500 million or above must use the income-based method. Only if a household business self-determines 2026 revenue below VND 500 million may it use the flat-rate method. If actual 2026 year-end revenue reaches VND 3 billion or above, it must switch to the income-based calculation method.
