E-Invoices, Social Insurance, and New Rules Every Household Business Must Know
Starting from mid-2025 and especially from 2026, household businesses in Vietnam will face a series of major regulatory changes in tax and social insurance obligations. These reforms mark the end of the long-standing fixed tax method and the beginning of a more transparent, declaration-based system aligned with actual revenue. To ensure compliance and avoid penalties, household businesses must understand and prepare for these changes in a timely manner.
Mandatory e-invoices and electronic cash registers from 1 June 2025
From 1 June 2025, household businesses with annual revenue of at least VND 1 billion, operating in sectors such as food and beverage, hotels, supermarkets, retail, passenger transport, and personal services, must use e-invoices generated by electronic cash registers directly connected to the tax authority’s system. They will also be required to declare taxes monthly or quarterly, maintain simplified accounting books, issue e-invoices in compliance with Decree 123/2020/ND-CP, and self-calculate and pay VAT, personal income tax (PIT), and business license fees where applicable. This reform replaces subjective fixed-tax assessments with a fairer, more transparent system based on actual revenue.
Abolition of the fixed tax method from 1 January 2026
Effective 1 January 2026, the fixed tax method will be abolished under Resolution 198/2025/QH15 and Decree 70/2025/ND-CP. All household businesses must comply with general tax management requirements, including tax registration, declaration, payment, invoicing, and periodic reporting as prescribed by law.
Higher VAT and PIT exemption threshold from 1 January 2026
Under the new Law on VAT 2024, the threshold for VAT and PIT exemption will double from VND 100 million to VND 200 million per year. Although businesses earning no more than VND 200 million annually will be exempt from VAT and PIT, they remain obligated to register, declare, maintain accounting books, and issue e-invoices in accordance with the Law on Tax Administration 2019.
Mandatory social insurance for owners from 1 July 2025
For the first time, household business owners directly involved in regular business activities will be required to participate in mandatory social insurance, alongside their employees (if any). This requirement, effective 1 July 2025 under the Law on Social Insurance 2024, underscores the State’s intent to extend social security coverage to all economically active individuals.
Key compliance actions to prepare
To adapt to this new regulatory environment, household businesses should promptly review and update their tax registration details with local tax authorities, including adjustments to their registered business codes if actual operations differ. They must also ensure they have the proper equipment and software for issuing compliant e-invoices connected to the tax authority’s system. Even under the simplified accounting regime, they must maintain complete records of revenues and expenses to support tax declarations and facilitate inspections. Businesses should declare taxes accurately and on time, avoiding underreporting or delays, which could incur penalties.
For household businesses with large, stable operations and regular employment, it may be worth considering a transition to a formal enterprise structure under the Law on Enterprises. This change could offer additional benefits, including improved access to credit, stronger legal protections, and clearer obligations.
In summary, from mid-2025 — and particularly from 2026 — household businesses must be ready to move away from the outdated fixed tax method toward a modern, transparent tax and social insurance regime. Adopting e-invoicing systems, maintaining proper records, fulfilling declaration and reporting obligations, and planning for social insurance contributions are all critical steps to ensure smooth and compliant operations during this transition.
