On the Ministry of Finance's Information Portal, a business household operating from before 2025 said that at the beginning of 2026, it had self-determined its estimated revenue for the whole year at about 600 million VND.
Based on the regulations at that time, on April 3, 2026, business households submitted tax returns for the first quarter of 2026 and paid the full amount of tax incurred into the state budget.
By April 29, 2026, the Government issued Decree No. 141/2026/ND-CP, raising the threshold for revenue not subject to value-added tax (VAT) and not subject to personal income tax (PIT) of households and individuals doing business from 500 million VND to 1 billion VND/year, applicable to the tax period of 2026.
Because the expected revenue is only about 600 million VND/year, business households believe that from the second quarter of 2026, they will not have to declare and pay taxes quarterly and only notify revenue once a year. At the same time, they requested tax authorities to guide the handling of VAT and PIT amounts paid in the first quarter of 2026.
Answering this content, Base Tax 19 HCMC cited the regulations in Decree No. 141/2026/ND-CP.
Accordingly, the threshold for revenue not subject to VAT and not subject to PIT for households and individual businesses is increased from 500 million VND to 1 billion VND/year.
For cases where revenue in 2026 is expected to be less than 1 billion VND but has submitted form 01/CNKD in the first quarter of 2026, business households shall prepare supplementary declarations to adjust VAT and PIT taxable revenue to 0 or send a notice of declaration cancellation to the tax authority.
In case of canceling the declaration, business households must submit a Notice of payment account numbers, e-wallet number related to production and business activities according to Form No. 01/BK-STK.
Regarding accounting books, from April 29, 2026, business households currently using form S2a-HKD must switch to using the Revenue Book for sales of goods and services (Form S1a-HKD) and the Other Tax Obligation Tracking Book, if any (Form S3a-HKD) according to Circular No. 152/2025/TT-BTC.
The tax authority also cited transitional regulations in Decree No. 141/2026/ND-CP. Accordingly, in cases where business households self-determine annual revenue from production and business activities from 1 billion VND or less but have declared and paid VAT and PIT according to previous regulations, the amount of tax paid will be handled according to regulations on handling overpaid tax.
For the above case, if self-determining annual revenue from production and business activities is from 1 billion VND or less, business households shall notify the tax authority of actual revenue generated in the year no later than January 31 of the following calendar year.
Specifically for the Q1/2026 tax return that has declared and paid the full amount of tax incurred into the state budget, business households are entitled to tax refunds according to the provisions of law on tax management for the surpaid tax amount.
