Thailand Inheritance & Gift Tax 2026: Complete Guide for Wealthy Expats

Thailand offers one of the world's most favourable frameworks for inter-generational wealth transfer. With an inheritance tax threshold of ฿100 million per heir, a fully exempt spouse, annual gift allowances of ฿20 million per recipient, and a scope limited exclusively to Thai-situated assets, Thailand's wealth transfer system is a compelling reason for HNW individuals to consider Thailand as their primary residence — particularly compared to France, Germany, or the UK.

What Is Thailand's Inheritance Tax?

Thailand introduced its inheritance tax in 2016 under the Inheritance Tax Act B.E. 2558. The system is deliberately designed to be light-touch — protecting family wealth while ensuring only very large estates face any tax burden.

The tax applies only to Thai-situated assets received by beneficiaries. Crucially, if each heir receives ฿100 million or less from any single estate, no inheritance tax is due at all. Only the portion exceeding ฿100M is taxed.

What Assets Are Subject to Thai Inheritance Tax?

• Real estate located in Thailand (condominiums, land, buildings)
• Deposits in Thai bank accounts
• Thai-registered company shares and securities
• Thai investment fund units
• Vehicles registered in Thailand
• Other assets legally situated in Thailand

Not included: Foreign bank accounts, overseas real estate, foreign investments, offshore company shares. These fall entirely outside Thai inheritance tax jurisdiction.

Inheritance Tax Rates & Calculations

Note: The ฿100M threshold applies per beneficiary, per estate. If you have 3 children and leave ฿300M, each child receives ฿100M — all fully tax-free.

Thailand Gift Tax: Annual Wealth Transfer

Thailand also allows structured annual gifting as a powerful wealth transfer tool. Gifts above certain thresholds are taxed as personal income, but the annual exemptions are generous:

Beneficiary Designation: Avoiding Probate

Thai bank accounts allow the account holder to name one or more direct beneficiaries. On death, funds transfer directly to named beneficiaries — outside the estate process, without probate delays or court involvement. This is particularly valuable for expats whose heirs may be in different countries.

Similarly, Thai condominium units can be passed to heirs with a straightforward land department transfer process, and the ฿100M threshold means that for most expats, this transfer is entirely tax-free.

Practical Wealth Transfer Strategies

Strategy 1: Buy Thai Property for Your Children

Purchase a Thai condominium (freehold, foreign-owned) in Bangkok or Phuket. On death, if the property is worth under ฿100M, it passes to your child with zero inheritance tax. Meanwhile, it generates 5–8% gross rental yield. Compare: the same property in France would face 30–45% inheritance tax.

Strategy 2: Thai Bank Deposits with Beneficiary Designation

Maintain a Thai bank account with named beneficiaries. Up to ฿100M passes directly to each named heir with no probate and no inheritance tax. Interest income on Thai deposits is taxed at a flat 15% withholding — modest and predictable.

Strategy 3: Annual Gifting Programme

Use the ฿20M/year/recipient gift allowance systematically. With a spouse and 2 children, ฿60M can be transferred annually tax-free. Over a decade: ฿600M transferred with zero gift tax — assuming genuine transfers of ownership with no reserved benefit.

Strategy 4: Hold Offshore Assets Offshore

Thai inheritance tax only applies to Thai-situated assets. Foreign property, offshore accounts, and international investments remain outside Thai tax jurisdiction entirely. A well-structured HNW individual can hold Thai lifestyle assets (home, car, bank account) in Thailand while maintaining offshore investment portfolios with zero Thai inheritance or wealth tax exposure.

Important Requirements for Gift Tax Exemption

To qualify for the annual ฿20M gift tax exemption, transfers must represent genuine gifts:

• Full transfer of ownership — the donor must not retain control or benefit from the asset
• Documented transfer (registered at Land Department for property, bank records for cash)
• Filed in the recipient's personal income tax return (PND.90)
• Not structured to disguise a commercial transaction

Why You Need a Thai Will — and How to Register It

Owning assets in Thailand — a condominium, a bank account, a vehicle — without a registered Thai will creates unnecessary risk for your heirs. Thai probate law applies to Thai-situated assets regardless of your nationality, and without a valid will, the distribution process can be slow, costly, and subject to Thai intestate succession rules that may not reflect your wishes.

Why a Thai Will Matters

• Speed: With a registered Thai will, your executor can begin asset transfer within weeks. Without one, Thai probate can take 6–18 months or longer.
• Certainty: You decide who receives what — your Thai condominium, your Thai bank balance, your vehicle. Without a will, Thai law decides.
• Cost: Contested or intestate estates incur higher legal fees and court costs. Consulting a Thai lawyer to draft and register your will is strongly recommended.
• Foreign heirs: If your beneficiaries are not Thai residents, a registered will with a clear executor dramatically simplifies the transfer process for them.

How to Make and Register a Thai Will

1. Choose your type: The most common for expats is a witnessed will (two witnesses, signed in their presence) or a holographic will (entirely handwritten and signed by the testator). A notarised or publicly registered will at the District Office (Amphoe) is the most secure.
2. Draft the will: List all Thai-situated assets clearly with their legal descriptions (condo title deed number, bank account details, vehicle registration). Name your executor and beneficiaries with their full legal names and identification numbers.
3. Register your will: The most secure option is to register your will officially — either at the local Amphoe (District Office) or through a Thai notary. This creates an official record and significantly reduces the risk of contest. A Thai lawyer can guide you through the process.
4. Keep a copy safe: Provide your executor with a copy and inform them of its location. Consider leaving a copy with your Thai lawyer.

Beneficiary Designation vs. Will

For Thai bank accounts, you can register a direct beneficiary with your bank — funds transfer outside probate entirely, with no court involvement. This is faster and simpler than a will for liquid assets. For real estate and other registered assets, a will (or inter vivos transfer during your lifetime) is required.

Frequently Asked Questions — Thailand Inheritance Tax

Does Thailand have inheritance tax?

Yes, but only on Thai-situated assets exceeding ฿100 million per beneficiary per estate. Below this threshold, no inheritance tax applies. Spouses are fully exempt.

Is my overseas property taxed in Thailand?

No. Thai inheritance tax only applies to assets physically situated in Thailand. Foreign property, offshore bank accounts, and foreign investments are outside Thai tax jurisdiction.

Can I give my children ฿20M every year tax-free?

Yes — the annual gift tax exemption is ฿20M per recipient per year for family members (children, spouse, parents). The gift must represent a genuine transfer of ownership. Tax of 5% applies only to amounts above this threshold.

Do I need a Thai will?

Having a Thai will is strongly recommended for assets situated in Thailand. It simplifies the estate process significantly. For bank accounts, beneficiary designation provides a faster, probate-free transfer route.
