The tax authority (An Giang Province Tax Sub-department 9) confirmed that household businesses (HKDs) that already filed Q1/2026 quarterly tax returns under the old threshold but now have annual revenue under VND 1 billion (qualifying as non-filing businesses under the new rules) do **not need to continue filing quarterly tax returns**. No procedure to cancel the filed return or amend it to show zero revenue is required — the tax authority does not demand this. Instead, HKDs need only submit a **Revenue Notification using Form 01/TKN-CNKD** by no later than 31 January 2027. This is important practical guidance for small household businesses following the government's increase of the tax-exempt revenue threshold to VND 1 billion per year, reducing administrative tax burdens for millions of household businesses.
Background
The taxable revenue threshold for household businesses was raised to VND 1 billion per year. Many HKDs had already filed Q1/2026 quarterly tax returns under the old threshold but now qualify as non-filing businesses under new rules. Conflicting guidance on social media (cancel the return, amend to show zero, etc.) created confusion.
Legal Basis
Under the new VND 1 billion annual revenue threshold rule: HKDs with revenue below this threshold are not required to file periodic quarterly tax returns — they only need to file a Revenue Notification using Form 01/TKN-CNKD.
Specific Guidance
- No need to cancel the already-filed Q1/2026 return
- No need to amend to show zero revenue
- Stop filing quarterly from Q2/2026 onward
- Only submit a Revenue Notification using Form 01/TKN-CNKD, by no later than 31 January 2027
If total annual revenue exceeds VND 1 billion, the HKD must continue filing periodic quarterly tax returns as normal.
