Best Country to Set Up a Business in Southeast Asia: Indonesia, Thailand, and Malaysia Compared

A regional operations director had already run the numbers twice. Indonesia and Malaysia had both cleared her company’s ownership requirement without a second conversation. Thailand had not. Midway through structuring the Thai entity, her legal team explained that the 100 percent foreign ownership she had assumed would carry over from the other two markets was not available for her company’s activity, not without a Thai majority partner or a Board of Investment application that would take months to process. Nothing about her business model had changed between the three markets. What changed was which country she was standing in.

That is the part most “ASEAN expansion” guides flatten into a single tax rate comparison, and it is the wrong place to start.

The Question That Actually Separates These Three Markets

Foreign ownership ceiling, not corporate tax rate, is the structural fork between these three countries. Indonesia and Malaysia both default to allowing high or full foreign ownership across most business activities. Thailand does not, and the gap between “default open” and “default restricted” changes everything about how a deal timeline and entity structure actually get built.

Indonesia’s foreign investment rules run through the Positive Investment List, which replaced the older Negative Investment List and now permits up to 100 percent foreign ownership across most sectors, with specific caps and conditions applying only to a defined set of restricted activities. The mechanics of how that list actually works, and which activities still carry ownership conditions, are explained in full in a separate breakdown of what replaced Indonesia’s Negative Investment List. Malaysia follows a broadly similar default, permitting 100 percent foreign ownership in most sectors under the Companies Act 2016, with exceptions concentrated in finance, telecommunications, oil and gas, distributive trade, and agriculture.

Thailand inverts that default entirely.

Thailand’s Foreign Business Act Is the Rule Everyone Underestimates

Under the Foreign Business Act B.E. 2542, any company where non-Thai shareholders hold 50 percent or more of registered capital is legally classified as foreign, and roughly 50 categories of business activity across three restriction lists require either a Thai majority partner, a Foreign Business License, or Board of Investment promotion before full foreign ownership becomes legally available. That is not a minor licensing formality layered on top of incorporation. It is a gating condition that determines the entity structure from day one.

What Actually Changed in 2026

Thailand delisted ten business categories from the FBA’s restricted lists in 2026, part of a broader push to align its investment rules more closely with regional competitors and attract higher value foreign direct investment. Companies operating in those newly delisted categories can now register with full foreign ownership without a license or BOI approval, a genuine liberalization worth checking against before assuming a business activity still requires the traditional workaround. For everything that remains restricted, the two realistic paths to full ownership are Board of Investment promotion, which also unlocks tax exemptions of up to thirteen years for qualifying projects, and a Foreign Business License, a harder and less predictable approval that Thai authorities have been scrutinizing more closely, particularly around nominee shareholder arrangements used to disguise actual foreign control.

Corporate Tax Rates Are Closer Than They Look Once Incentives Enter the Picture

Headline corporate income tax rates across the three markets sit within a few points of each other, which makes them a weaker differentiator than most comparison guides treat them as.

• Indonesia: 22 percent standard rate, with a 50 percent reduction available for approved investment plans between IDR 100 billion and IDR 500 billion, and a full corporate income tax exemption of up to 20 years for qualifying pioneer sector investments above that threshold
• Thailand: 20 percent standard rate, with a progressive structure for qualifying small companies (0 percent on the first THB 300,000 of net profit, 15 percent up to THB 3 million, 20 percent above that), and Board of Investment promoted projects eligible for exemptions of up to 13 years
• Malaysia: 24 percent standard rate, the highest headline figure of the three, though qualifying new companies under Pioneer Status or technology-based startup criteria can access a 0 percent rate for their first three years of assessment

Both Indonesia and Thailand now apply the OECD’s Pillar Two global minimum tax framework to multinational groups above the EUR 750 million consolidated revenue threshold, which changes how much a headline tax holiday actually saves for a large enough group. How that recapture mechanism works specifically for Indonesia, and why a zero percent rate no longer produces the same net benefit it once did for in-scope groups, is covered in detail in a dedicated look at how the global minimum tax changed Indonesia’s tax holiday incentive. A group large enough to trigger Pillar Two anywhere needs to run this analysis regardless of which of the three markets it is comparing.

Minimum Capital Looks Simple Until You Read the Fine Print

On paper, Malaysia looks like the cheapest market to enter, and Thailand looks the most demanding. In practice, the real capital requirement in each market depends heavily on what the business actually intends to do.

Indonesia requires a minimum paid up capital of IDR 2.5 billion per business classification under BKPM Regulation No. 5 of 2025, with the total investment plan still expected to exceed IDR 10 billion per classification over time. The full breakdown of how that figure interacts with notary, licensing, and other establishment costs is covered in a separate PT PMA establishment cost guide. Thailand’s foreign-owned companies typically need at least THB 2 million in registered capital for standard restricted activities, though specific sectors seeking exemption from the ownership cap, such as wholesale or retail operations with capital above THB 100 million, face a materially higher threshold tied directly to the ownership exemption itself. Malaysia’s legal minimum is a nominal RM1, but that figure is largely theoretical. Sponsoring a foreign employee’s Employment Pass typically requires paid up capital of around RM 500,000, and licensed trading, food and beverage, or wholesale and retail businesses commonly need RM 1,000,000 or more to satisfy the relevant licensing authority.

None of these figures are directly comparable on their face, since each one is answering a slightly different regulatory question. What they share is that the number quoted in a generic “minimum capital” comparison table is rarely the number a specific business actually needs.

How Fast Each Market Actually Moves

Malaysia’s incorporation process is genuinely the fastest of the three on paper, with the Companies Commission of Malaysia typically approving and registering a Sdn Bhd within one to seven working days once documentation is complete, though full operational readiness, including bank account opening, tends to run four to eight weeks in total. Indonesia’s PT PMA process, covered step by step in a dedicated guide to setting up a PT PMA, follows a broadly comparable overall timeline once KBLI classification, capital verification, and licensing are sequenced correctly. Thailand’s timeline is the least predictable of the three specifically because it depends on which ownership pathway a company needs. A business in an unrestricted or newly delisted category moves at a pace similar to the other two markets. A business requiring Board of Investment promotion or a Foreign Business License is working against a fundamentally different, and typically longer, approval clock.

Market Size and What It Actually Buys You

Population and market depth are the variable a pure compliance comparison leaves out entirely, and they matter more for some business models than others. Indonesia’s population of more than 270 million makes it Southeast Asia’s largest single market by a wide margin, a scale advantage covered in more depth in a look at the most promising investment sectors in Indonesia for 2026. Thailand and Malaysia offer smaller domestic markets, at roughly 70 million and 34 million people respectively, but each brings its own regional advantages, Thailand’s established manufacturing and export infrastructure, and Malaysia’s position as a regional services and logistics hub with strong English-language business infrastructure.

A Practical Way to Decide

Bringing the ownership ceiling, tax structure, capital requirement, and timeline together, the decision usually comes down to a small number of genuinely deciding factors rather than a long checklist.

• If the business needs full, unencumbered foreign ownership quickly and the activity is not in a narrow restricted category, Indonesia and Malaysia both clear that bar by default in most sectors
• If the business is in manufacturing, digital services, or another Board of Investment eligible category and can absorb a longer approval timeline in exchange for up to 13 years of tax exemption, Thailand’s BOI route is genuinely competitive
• If market scale and long-term consumer demand growth matter more than initial setup speed, Indonesia’s population and economic size are difficult to replicate elsewhere in the region
• If speed to a registered, operational entity is the immediate priority, Malaysia’s SSM process is the fastest on paper of the three

For companies also weighing options further afield, a similar decision framework, applied to Indonesia against Vietnam rather than Thailand and Malaysia, is covered in a separate comparison of Indonesia and Vietnam for business expansion.

XPND’s market entry advisory team works through exactly this comparison for companies still deciding between Southeast Asian markets, mapping the actual foreign ownership pathway for a specific business activity before a tax rate comparison even enters the conversation. The lowest tax rate on a spreadsheet means very little if the ownership structure it assumes turns out to require a local majority partner nobody budgeted for.
