The Ministry of Finance confirms that under Article 9(3)(a) of Decree No. 262/2025/ND-CP dated 14 October 2025, the business lines of a science and technology (S&T) organization must align with the fields of activity stated in its S&T organization registration certificate issued by a competent authority.

The rule is intended to ensure consistency between actual business activities and the stated purpose for which the S&T organization was established.

Chi trả lương bằng tiền mặt có được tính vào chi phí hợp lý khi tính thuế TNDN không
The Ministry of Finance clarified whether cash wage and salary payments to employees qualify as deductible expenses for corporate income tax (CIT) purposes under CIT Law 67/2025/QH15 and Decree 320/2025/ND-CP. A construction company pays workers between VND 11-22 million per month in three cash instalments (on the 10th, 20th, and 31st of each month), each payment below VND 20 million, supported by payroll sheets, timesheets, and cash vouchers. Under Decree 320/2025/ND-CP, salary and wage expenses are deductible for CIT if: actually paid, properly documented (payroll sheets, timesheets, cash payment vouchers), and stipulated in labour contracts or collective bargaining agreements. Applicable rules on non-cash payment thresholds must also be observed. The Ministry confirmed that cash salary payments with adequate documentation and compliant with labour, accounting, and tax regulations are deductible as reasonable business expenses. Enterprises must ensure compliance with non-cash payment regulations for applicable transaction thresholds.

Hướng dẫn ghi nhận doanh thu kế toán đối với doanh nghiệp kinh doanh hạ tầng khu công nghiệp cho thuê lại đất trả tiền một lần
The Department of Accounting and Auditing Management and Supervision (Ministry of Finance) confirmed that industrial zone infrastructure enterprises subleasing state-leased land (where the state lease uses a lump-sum payment model) must determine the nature of their sublease contract — as asset rental (VAS 06) or service provision (VAS 14) — based on the contract terms, land law provisions, and actual circumstances. Revenue must be **allocated over the lease period** for operating leases rather than recognized in full upon receipt of payment. This is important revenue accounting guidance for industrial zone enterprises, affecting financial statement presentation and CIT declarations based on revenue actually earned each period.
Decree 236/2025/ND-CP: Detailed Regulations on Certain Articles of Resolution No. 107/2023/QH15 Regarding the Application of Supplementary Corporate Income Tax Under Global Anti-Base Erosion Rules

Decree 236/2025/ND-CP, effective from October 15, 2025, provides detailed regulations on the application of supplementary corporate income tax (CIT) under Pillar Two of the Global Anti-Base Erosion (BEPS 2.0) framework proposed by the OECD. This Decree implements National Assembly Resolution 107/2023/QH15, ensuring that large multinational enterprise (MNE) groups pay a minimum effective tax rate of 15% globally. The Decree applies to multinational groups with consolidated global revenue of at least 750 million Euros in at least 2 of the 4 consecutive fiscal years prior. Entities within these groups operating in Vietnam must comply with supplementary tax rules if their effective tax rate falls below 15%. For small and medium-sized enterprises (SMEs) not part of such large groups, this Decree has no direct impact. The Decree details methods for determining qualifying income and taxes, calculating effective tax rates, and mechanisms for collecting supplementary taxes (including the Income Inclusion Rule - IIR and Undertaxed Profits Rule - UTPR). Businesses must file GloBE Information Returns and Supplementary CIT Returns, with specific forms and guidance provided. The Decree also includes transitional rules and safe harbors to reduce compliance burdens during the initial implementation phase.
Consolidated Document No. 113/VBHN-VPQH: Corporate Income Tax Law (consolidated through April 2026)
Văn bản hợp nhất số 113/VBHN-VPQH: Luật Thuế thu nhập doanh nghiệp (hợp nhất đến tháng 4/2026)
This is the official consolidated version of Vietnam's Corporate Income Tax (CIT) Law (Law No. 67/2025/QH15, effective from 1 October 2025 and applied from the 2025 tax period), published by the National Assembly Office on 20 May 2026. It integrates every amendment made to date, through Law No. 09/2026/QH16, which took effect on 24 April 2026. This is the core legal text every business operating in Vietnam must follow when calculating and declaring CIT. On tax rates, the standard rate remains 20 percent, but businesses with annual revenue of up to VND 3 billion pay only 15 percent, and those with revenue from over VND 3 billion up to VND 50 billion pay 17 percent - a notable relief measure for small and micro enterprises. The law also adds a full CIT exemption for businesses whose annual revenue falls below a threshold still to be set by the Government (Article 4.14a, effective 1 January 2026); the specific figure will be issued later in an implementing decree. The law also confirms that foreign enterprises running e-commerce or digital-platform businesses in Vietnam are taxable even without a permanent establishment there. On incentives, preferential rates of 10 percent (for 10, 15, or 25 years depending on the sector), plus tax holidays of 2-4 years and 50 percent reductions for a further 4-9 years, continue to apply to high-tech, strategic technology, R and D, software production, renewable energy, and agriculture in disadvantaged areas, among other fields. The new High-Tech Law (effective 1 July 2026) significantly expands incentive eligibility for strategic-technology and high-tech enterprises, including a new 10 percent rate for 25 years - the longest incentive period offered to date. SME owners and accountants should re-check how their revenue is classified to confirm which of the 15/17/20 percent rates applies to them, and should watch for the implementing decrees still to come, especially the one that will set the micro-enterprise exemption threshold.

Miễn giảm thuế TNDN 2 năm cho doanh nghiệp chuyển đổi từ hộ kinh doanh theo Luật số 67/2025/QH15
The Ministry of Finance provides guidance on the two-year Corporate Income Tax (CIT) exemption applicable to enterprises converted from household businesses under Law No. 67/2025/QH15. The law takes effect from 1 October 2026 and applies from the 2025 tax period onward. To determine eligibility, the tax authority directs enterprises to assess their actual circumstances against the requirements set out in Decree No. 320/2025/ND-CP dated 15 December 2025, which provides detailed guidance for implementing the CIT Law.
Law on Science, Technology and Innovation No. 93/2025/QH15 (Consolidated Text)
Luật Khoa học, Công nghệ và Đổi mới sáng tạo số 93/2025/QH15 (văn bản hợp nhất)
The Law on Science, Technology and Innovation No. 93/2025/QH15, passed by the National Assembly on 27 June 2025 and effective from 1 October 2025, replaces Vietnam's previous legal framework for science and technology. This is a consolidated text that folds in amendments from the Law on High Technology No. 133/2025/QH15 and the Law on Digital Transformation No. 148/2025/QH15, both effective from 1 July 2026. The provision businesses should pay closest attention to is Article 35: a company's expenses on scientific research, technology development and innovation - including amounts it spends funding such activities - are treated as deductible expenses when determining corporate income tax (CIT) taxable income, at an enhanced rate the Government will set out in forthcoming implementing regulations. This functions like an "R&D super-deduction" mechanism used in many other countries. Science and technology enterprises, science and technology organizations, and non-public organizations active in this field also receive priority access to CIT, VAT, import and export duty incentives, credit, land and public procurement on the same footing as public institutions. The law also creates a "controlled testing" (regulatory sandbox) mechanism letting businesses trial new technologies, products, services or business models not yet covered by current law, for up to 3 years with one renewal of up to another 3 years; establishes a National Venture Capital Fund and local venture capital funds to invest in innovative startups; and allows the Vietnam Stock Exchange to open a dedicated trading board for innovative startup shares. SME owners working in technology, R&D or innovation should watch for the government's upcoming implementing decrees to confirm exact deduction rates and eligibility conditions.
Meal Allowances and Overtime Pay Under Product-Based Pay Schemes: PIT Treatment and CIT Deductibility
Tiền ăn ca và thu nhập làm thêm giờ theo lương khoán sản phẩm: thuế TNCN và chi phí TNDN
The Ministry of Finance provided guidance on PIT and CIT treatment for meal allowances and overtime pay where employees are remunerated under a product-based (lump-sum output) pay scheme. From 01/7/2025, meal allowances that do not exceed the limit prescribed by labor law are not counted as taxable PIT income. Reasonable, documented meal allowance payments are deductible for CIT purposes. For overtime pay, the incremental portion of income paid above the normal working day rate is PIT-exempt. Product-based overtime pay is deductible for CIT if supported by full documentation (labor contracts, task assignment decisions, timesheets, payslips, payment vouchers). This guidance is based on Circular 40/2021/TT-BTC and applicable tax regulations effective from 2025.

Tax Sub-department 25 of Ho Chi Minh City responded to a query from Ms. Nguyen Thi Loan regarding eligibility for the 3-year CIT exemption for newly established enterprises under Resolution 198/2025/QH15. The authority clarified that the enterprise must qualify as a small and medium enterprise (per Article 5, Decree 80/2021/ND-CP) and must satisfy the conditions in Clause 3, Article 7 of Decree 20/2026/ND-CP. Among the disqualifying conditions: the exemption does not apply if the legal representative, general partner, or highest capital contributor of the new enterprise has held an equivalent role in another enterprise that is currently operating or was dissolved less than 12 months prior. The tax authority did not issue a definitive conclusion for the taxpayer's specific situation, instead instructing Ms. Loan to apply the cited regulations to her own facts to determine eligibility.
3-Year Tax Exemption for Newly Established SMEs Upon Ownership Transfer
Miễn thuế 3 năm cho doanh nghiệp nhỏ và vừa mới thành lập khi chuyển đổi chủ sở hữu
The Ministry of Finance clarified the eligibility conditions for the 3-year corporate income tax (CIT) exemption for newly established small and medium enterprises (SMEs) under National Assembly Resolution 198/2025/QH15 and Government Decree 20/2026/ND-CP. The query concerned a single-member LLC established in early 2025 that changed ownership in September 2025 and hired a foreign director. To qualify for the 3-year CIT exemption, a newly established SME must meet conditions set out in Resolution 198/2025/QH15 and Decree 20/2026/ND-CP, including that the owner(s) must not have previously established or contributed capital to any other enterprise. The Ministry confirmed that if both the former and new owner had never established or invested in any other company, the enterprise may still be eligible for the exemption. Eligibility is assessed based on the actual circumstances at the time of establishment and throughout the company's operation. The enterprise should maintain supporting documentation to present to the tax authority upon request.
