VI Our company currently collaborates with and provides a trading platform for many household and individual businesses. I heard that the newly issued Circular 50/2026/TT-BTC has completely changed the declaration forms and introduced new regulations on tax refunds and bank account updates. Could you please advise on the core new points, potential risks, and how we and our partners need to comply with these regulations? Let’s explore this further with Pham Consult!
Below is detailed advice regarding the new regulations on tax procedures for household/individual businesses according to Circular 50/2026/TT-BTC (effective from May 13, 2026):

Main content
– Scope of application clarified: Detailed regulations on documents and procedures for revenue notification, tax declaration, tax payment, tax refund, notification of business location, temporary suspension, and termination of business operations for household and individual businesses.
(Based on Article 1 of Circular 50/2026/TT-BTC)

Biggest Impact
The new regulations directly impact business households, chain stores, individuals conducting e-commerce, and accounting and tax service providers. Businesses collaborating with household businesses need to quickly update to the new form system, cross-check invoice data, tax identification numbers, and payment records to minimize the risk of invalid expense deductions during accounting.
Risks of non-compliance:
– Continuing to use old forms when filing or claiming tax refunds will result in the tax authorities rejecting the application, leading to delays in tax refunds or penalties for late payment and additional payments due to missed tax filing deadlines.
– Individuals and household businesses failing to update their e-wallets on time will increase the risk of discrepancies in tax management data, affecting payment transactions and the verification of electronic invoice data by the tax authorities.
Proposed Action Plan:
– Update and replace all declaration forms, revenue notification forms, statements, and tax refund request forms in accounting software and internal software with the new forms (01/TKN-CNKD, 01/CNKD, 01/BĐS, 02/BK-KTBĐS).
– Compile a list of related business households/individuals currently cooperating, and send reminders to them to complete the deadline for updating bank accounts before July 31, 2026.
Notes and Recommendations for Customers:
– Immediate Effectiveness: The Circular takes effect immediately from the date of signing (May 13, 2026). Therefore, businesses and individuals do not have a transition period for tax declaration forms; all documents generated or submitted from this date onwards must use the new forms.
(Based on Clause 1, Article 4 of Circular 50/2026/TT-BTC)
– The deadline for notifying account numbers is July 31, 2026: For groups of households/individuals currently operating with annual revenue of VND 1 billion or less who have not yet submitted their Q1/2026 tax return or have not yet sent the notification of account/e-wallet numbers according to the old regulations, this is the mandatory deadline to fulfill the notification obligation.
(Based on Clause 2, Article 4 of Circular 50/2026/TT-BTC)
