On April 9, 2026, the Tax Department received Official Letter No. 676/LDO-QLDN2 from the Lam Dong Provincial Tax Department requesting guidance on difficulties encountered in the implementation of electronic invoices in the locality. To address this issue, Official Letter 2218/CT-CS was issued, not only responding specifically to Lam Dong but also playing a crucial role for many businesses nationwide currently undergoing transitions according to the latest Circulars and Decrees of 2025.
The issuance of Official Letter 2218/CT-CS is necessary as legal documents such as Decree 70/2025/ND-CP and Circular 32/2025/TT-BTC begin to be implemented, requiring uniformity in understanding and implementation between tax authorities at all levels and taxpayers.
The core legal basis in Official Letter 2218/CT-CS
The core content of Official Letter 2218/CT-CS is based on the four most important legal pillars currently in place. Understanding these legal grounds is key for businesses to fulfill their tax obligations correctly.
Tax Administration Law No. 38/2019/QH14
The primary and highest legal basis is Clause 2, Article 91 of Law No. 38/2019/QH14 on Tax Administration. This is the fundamental legal framework regulating the application of electronic invoices when selling goods and providing services. The law clearly stipulates that individuals and business organizations must completely switch to electronic invoices to ensure consistency in national data management. Circular 2218/CT-CS further affirms the continuity of this document in 2026.
Decree 123/2020/ND-CP and its amendments in Decree 70/2025/ND-CP
This is the central point emphasized in Official Letter 2218/CT-CS. Decree 123/2020/ND-CP is the original document on invoices and receipts. However, the most noteworthy point is the amendment and supplementation at point a, clause 3 and clause 8, Article 1 of Decree 70/2025/ND-CP (issued on March 20, 2025).
These new regulations focus on:
- Principles of invoice creation and management: The process has become more stringent, requiring greater timeliness and accuracy.
- Invoices generated from cash registers: This is a form of electronic invoice that connects directly to the tax authorities for data transfer. Circular 2218/CT-CS clarifies that businesses (restaurants, supermarkets, shopping malls, etc.) must ensure the necessary technical infrastructure for smooth data transmission and reception.
Regulations regarding the timing of invoice issuance.
Incorrectly determining the timing of invoice issuance is a common mistake made by accountants. Circular 2218/CT-CS reiterates this regulation to ensure businesses do not violate the timing of revenue recognition and tax obligations. Accordingly, the time of issuing an electronic invoice for the sale of goods is the time of transfer of ownership or the right to use the goods, regardless of whether payment has been received or not. This regulation is preserved in its entirety in Circular 2218/CT-CS to avoid disputes regarding the timing of tax calculation.
Implementation guidelines are provided in Circular 32/2025/TT-BTC.
Circular 32/2025/TT-BTC of the Ministry of Finance provides detailed guidance on the implementation provisions. Based on Clause 5, Article 12 of this Circular, Official Letter 2218/CT-CS outlines the roadmap and handling measures during the transition period, helping businesses in Lam Dong province in particular and the whole country in general avoid confusion with changes in forms and methods of sending and receiving data.
The entities using invoices without codes are specified in Official Letter 2218/CT-CS.
One of the most important points clarified in Official Letter 2218/CT-CS is the identification of entities using electronic invoices without a tax authority code.
Based on the proposal in document 676/LDO-QLDN2, the Tax Department has expressed strong agreement with the opinion of the Lam Dong Provincial Tax Department. Specifically:
- Eligibility criteria: Businesses permitted to use invoices without codes must meet stringent standards regarding scale and business sector (typically sectors such as electricity, petroleum, postal and telecommunications, banking, etc.), and especially must have an information technology system that ensures regular data transmission to the tax authorities.
- Approval process: The fact that Lam Dong Provincial Tax Department proactively identified and proposed the target group demonstrates flexibility in management, and Circular 2218/CT-CS affirms the authority and close coordination between local and central tax authorities.
Businesses should note that the switch to invoices without codes, as mentioned in Official Letter 2218/CT-CS, does not mean a relaxation of management; on the contrary, businesses will have a greater responsibility for self-monitoring data and reporting.
