What is the standard CIT rate in Vietnam for 2026?

The standard Corporate Income Tax (CIT) rate remains at 20%. However, micro and small enterprises may qualify for reduced rates of 15% or 17%.

Does a large capital investment of VND 6 trillion still guarantee tax incentives?

No. As of the 2026 tax year, automatic incentives based solely on a VND 6 trillion capital threshold have been removed. Incentives are now primarily determined by sector and location.

What is the new non-cash payment threshold for tax deductions?

The threshold has been tightened. For an expense to be deductible, payments of VND 5 million or more must be made via non-cash methods (e.g., bank transfer).

Does Your Capital Size Still Earn Tax Perks? The Truth About Vietnam’s

Dear Clients and Partners,

For over a decade, foreign investors entering the Vietnamese market followed a simple rule of thumb: "Go big or go home." Large-scale capital investments were often the golden ticket to generous tax holidays and preferential Corporate Income Tax (CIT) rates. However, as we move through 2026, that landscape has fundamentally shifted.

The implementation of the Corporate Income Tax Law 2025 (Law No. 67/2025/QH15) and its guiding Decree No. 320/2025/ND-CP has officially recalibrated how Vietnam rewards investment. If your business strategy still relies on the "large-capital project" incentives of the past, you may be in for a significant fiscal surprise.

At BLaw Vietnam, we believe that staying ahead of these regulatory changes is the only way to ensure true tax optimization. In this article, we will break down why capital size is no longer the primary driver of tax perks and what your business must do to remain compliant and cost-effective in this new era.

The End of the "One-Size-Fits-All" Size-Based Incentives

Historically, projects with a capital investment of VND 6 trillion or more were eligible for specific tax incentives purely based on their scale. As of the 2026 tax year, this automatic privilege has been removed. The Vietnamese government has pivoted from a "quantity-led" to a "quality-led" incentive framework.

Under the new 2026 regime, tax perks are now laser-focused on Sector and Location. Simply having a large balance sheet is no longer enough. To earn a seat at the table for preferential rates, your investment must now align with the country's strategic priorities, such as:

High-Tech & Digital Innovation: R&D, semiconductor chip testing, and AI data centers.
Strategic Manufacturing: Automobile assembly and key chemical production.
Small and Medium Enterprise (SME) Support: Incubators and co-working spaces.

Understanding the 2026 Tiered Tax Rates for SMEs

While large capital projects are losing their automatic perks, the 2026 law introduces a welcome change for smaller players. For the first time, Vietnam has implemented tiered tax rates based on annual revenue, providing a much-needed boost for micro and small enterprises (MSEs).

Micro-Enterprises (Revenue ≤ VND 3 billion): Subject to a reduced 15% CIT rate.
Small Enterprises (Revenue > VND 3 billion to ≤ VND 50 billion): Subject to a 17% CIT rate.

This shift is designed to formalize the economy and encourage business households to convert into legal entities. For foreign investors operating in specialized legal services or niche consulting, these tiered rates can offer a significant competitive advantage if your structure is optimized correctly.

The Global Minimum Tax (GMT) Ripple Effect

One cannot discuss the 2026 tax recalibration without mentioning the Global Minimum Tax (GMT) : Pillar Two. With Vietnam officially adopting a 15% domestic top-up tax, the traditional "tax holiday" (0% CIT) is becoming less effective for multinational enterprises (MNEs) with consolidated revenues exceeding EUR 750 million.

If your parent company falls into this category, the tax perks you once enjoyed in Vietnam might be "clawed back" in your home jurisdiction. To combat this, the Vietnamese government is shifting toward non-tax incentives, such as support from the Investment Support Fund. This includes grants for human resource training, infrastructure development, and high-tech R&D: incentives that do not erode your effective tax rate under Pillar Two rules.

Expansion Projects: New Capital Thresholds for 2026

For existing businesses looking to grow, M&A and Corporate Finance strategies must now account for stricter expansion thresholds. To qualify for continued or additional incentives as an "expanded investment project" under Decree 320, you must meet one of the following:

Absolute Capital: At least VND 40 billion for encouraged sectors or VND 20 billion for encouraged locations.
Relative Growth: An increase in fixed asset cost or designed capacity of at least 20% compared to the pre-expansion period.

Failing to document these thresholds accurately during a tax settlement can lead to the total disallowance of expansion perks, resulting in a retroactive tax bill at the standard 20% rate.

7 Mistakes You’re Making with Tax Optimization in 2026 (and How to Fix Them)

As tax administration becomes increasingly automated in 2026, the margin for error has disappeared. Based on our experience at BLaw Vietnam, here are the top pitfalls businesses face:

The VND 5 Million Trap: In 2026, the non-cash payment threshold for deductible expenses has been tightened to VND 5 million (down from VND 20 million). Any payment above this amount made in cash is now non-deductible.
License Misalignment: Generating revenue from activities not explicitly listed in your Investment Registration Certificate (IRC). This is a primary trigger for losing preferential rates.
Ghost Supplier Invoices: Using invoices from high-risk or inactive entities. The General Department of Taxation now uses "Big Data" to flag these automatically.
Thin Capitalization Issues: Ignoring the 30% EBITDA cap on interest deductibility for related-party loans under Decree 132.
Incorrect Residency Status: Miscalculating the 183-day rule for expatriates, leading to PIT finalization errors.
Missing the 3-Way Match: Failing to align the invoice, contract, and bank transfer documentation.
Ignoring the Digital Economy Rules: Foreign entities providing digital services to Vietnam are now subject to tax even without a physical office.
