Thailand Holding Company Setup: Ownership, Tax, and Investment Scope

Key takeaways

• Foreign-business status must be assessed for the holding company and each Thai subsidiary; inserting a Thai-incorporated parent does not settle the question.
• Dividend relief depends on the payer, voting interest and holding period. A qualifying dividend does not exempt unrelated earnings.
• An investment mandate should distinguish acquiring equity from supplying services or extending loans.
• Keep acquisition dates and tax evidence at transaction level, so a later distribution or exit can be tested before approval.
• Company registration, permission to conduct an activity and the tax treatment of its receipts are separate decisions.

Map the ownership chain before choosing investments

Start with the legal identity of every proposed shareholder. Under the Foreign Business Act B.E. 2542 (1999), a Thai-registered juristic person can itself be a foreigner where at least half of its capital shares are held by the relevant foreign persons or entities. The definition also addresses holdings through another qualifying juristic person. The Department of Business Development explanation therefore matters at more than the top line of a group chart.

For example, a Thai subsidiary with 60% of its shares held by a Thai-incorporated holding company cannot be classified merely by the parent’s place of incorporation. First establish whether that parent falls within the statutory foreigner definition. Then classify the subsidiary’s own activity. This is a direct application of the ownership test, rather than a separate exemption for corporate groups.

For each entity, record capital ownership, nationality or place of formation, the intermediate entities and any special sector conditions. Keep voting arrangements in a separate column: they affect governance, while the Foreign Business Act definition must be applied on its own terms. A group chart is an input to the legal analysis, not permission to operate. Do not substitute an effective economic percentage for the statutory test.

Thai participation must be real. Official guidance on nominee shareholding identifies arrangements used to assist prohibited foreign business as unlawful. Where a proposed structure depends on a shareholder merely lending a name, stop and redesign it around genuine investment or an available lawful permission route.

Separate share ownership from group business activities

The DBD ruling on shares and dividends addresses a narrow activity, rather than every business a parent might add later. Write the holding company’s intended activities as transactions, not as a long list of objects. “Acquire 70% of an operating company and receive dividends” describes a different role from “invoice that company monthly for management” or “lend funds and earn interest.” The registration objects should accommodate the intended role, but cannot replace the assessment of what the company actually does.

The Foreign Business Act distinguishes prohibited, restricted and other activities. A Foreign Business License (FBL), a Foreign Business Certificate (FBC) or a specific exemption may be relevant, depending on the activity and route. The OSOS explanation of restricted activities includes the broad service category and notes that prescribed exceptions exist. Do not conclude that every intragroup service is exempt, or that every transaction requires the same permission.

Separate the parent’s permission analysis from that of each investee. A subsidiary’s approval does not describe services supplied by its shareholder. Similarly, Thailand Board of Investment (BOI) ownership treatment applies to qualifying promoted projects and remains subject to other laws and project conditions, as its Thai-language foreign-shareholding guidance explains. Merely placing shares in a parent does not establish promoted status for that parent.

Use a written investment mandate to identify permitted asset categories, countries, maximum commitments, approval authority and activities excluded until separately cleared. If money will be raised or managed for outside investors, commission a dedicated regulatory assessment before treating the vehicle as an ordinary proprietary holding company. The same discipline applies before adding treasury services or an investment involving land: expand the review with the proposed transaction, rather than assuming the original mandate covers it.

The two routes below share a parent, but they need different evidence before money starts moving.

Test tax treatment for each income stream

There is no general tax-free status created by incorporating a holding company. The ordinary corporate income tax rate is 20% of taxable net profit, as shown in the current corporate return instructions ; another rate or relief needs its own eligibility basis. The Revenue Department’s corporate return guidance also confirms that a company without operating revenue still has financial-statement and corporate-return obligations.

Dividends from a Thai company

For an ordinary unlisted Thai limited company receiving qualifying Thai-company dividends, Revenue Code section 65 bis(10) generally includes only half the dividend in taxable income. Full exclusion is available where the recipient holds at least 25% of all voting shares in the payer and the payer has no direct or indirect holding in the recipient. The listed-company alternative is outside this private-company planning model.

The Revenue Department explanation of section 65 bis also requires holding the shares for at least three months before the dividend income arises and retaining them for at least three months afterward. Failure of the timing condition removes the relief under this provision; a stake below 25% does not by itself remove the half exclusion where its conditions are met. Track voting shares and both holding-period dates before scheduling a dividend or selling the investment.

Dividends from a foreign company

A different exemption applies under section 5 vicies of consolidated Royal Decree No. 10 , inserted by Royal Decree No. 442. The Thai limited or public limited recipient must hold at least 25% of the foreign payer’s voting shares for at least six months from acquisition to receipt. The dividend must come from profits subject to tax in the payer’s country at a rate of at least 15%, subject to the decree’s wording on local statutory reductions or exemptions.

That last condition should not be reduced to “the subsidiary paid 15% in cash.” Identify the profit from which the distribution comes, the applicable tax regime and any statutory relief. Obtain the payer’s financial statements and supporting tax analysis; a bank transfer proves receipt, not eligibility. If the evidence fails, calculate the taxable result and any available foreign-tax credit separately rather than assuming exemption.

Other earnings and the next distribution

Interest, service income and share-disposal gains require their own treatment; the Revenue Department corporate tax summary starts from net business profit, not a company’s chosen label. Screen fees and lending for withholding, value added tax (VAT) or specific business tax (SBT) as applicable. A later dividend to a foreign corporate shareholder not carrying on business in Thailand generally attracts 10% Thai withholding under domestic rules; check the recipient, treaty and any specific relief separately.

Use this mandate ledger as a working approval record. It links the event that produces cash to the evidence needed before a director authorizes it; it is not a substitute for the tax computation.

Build the company around an investment evidence file

Establish the Thai limited company with documents that can support its investment decisions afterward. The DBD memorandum guidance requires at least two natural-person promoters, each subscribing for a share. Its incorporation checklist covers full subscription, the statutory meeting and payment of at least 25% of share value. A corporate parent investor must therefore distinguish its shareholder role from the natural-person promoter role.

Agree the head office, investment objects, share allocation, directors, signing authority and funding before filing. The underlying Thailand company registration requirements apply to the company’s formation; the investment mandate then controls which proposed acquisitions or contracts receive approval. Paid-up capital is equity contributed to the company, not a government registration charge or a loan from a shareholder.

New-company filings use DBD Biz Regist. The DBD’s October 27, 2026 notice confirms that new incorporations moved to that online channel from July 1, 2026. Prepare identity verification, signing and supporting documents for the current system; submitting an application is not the same as receiving completed registration.

• Ownership file: investor identities, corporate ownership chain, share register, transfer instruments and evidence of genuine contributions.
• Investment file: target company information, acquisition agreement, voting rights, acquisition date and any cross-holdings.
• Cash-flow file: a separate description and supporting agreement for each dividend, fee, loan, interest receipt and planned disposal.
• Authority file: incorporation records, board approvals, signing powers and any activity-specific permission or exemption analysis.

For cash entering from abroad, equity contributions and documented shareholder loans need distinct records so the investment ledger agrees with the funding trail. Preserve the remittance purpose and recipient account evidence alongside the approving resolution. Avoid posting every incoming transfer to capital merely because the sender owns the company.

Registration is complete when the approved company records have been issued and checked. Investment readiness additionally requires the relevant activity decisions, bank arrangements and tax evidence. Appoint responsibility for bookkeeping, audit and returns from the outset, including periods when the parent only holds investments. Reassess the mandate when a new subsidiary, fee contract, financing arrangement or exit is proposed.

Authorize a holding investment when three records agree

Proceed when the ownership chart, transaction mandate and tax evidence ledger describe the same structure. The chart should establish who owns each entity; the mandate should identify the activity and approval authority; the ledger should explain the expected receipt and its treatment. A mismatch is a reason to pause the transaction, even if the company has already been incorporated.

Prioritize the next binding event: acquiring shares, receiving a dividend, signing a service agreement or selling an investment. Resolve the conditions that affect that event first. Do not authorize a distribution on an untested exemption. If the structure depends on nominee participation, an unexplained profit-tax assumption or a permission belonging only to another group entity, escalate that issue before funds or contractual commitments move.
