Understanding VAT in Thailand: Rates, Rules, and What Businesses Need to Know

Value Added Tax (VAT) in Thailand is an indirect consumption tax levied on the value added at each stage of production and distribution of goods, the provision of services, and imports. While the statutory rate is 10%, the Thai government has maintained a temporary reduced rate of 7% for decades—most recently extended under Royal Decree No. 807 through September 30, 2027.

Understanding VAT in Thailand: Rates, Rules, and What Businesses Need to Know

Whether you are launching a startup in Bangkok, importing goods into Laem Chabang, or simply checking the bottom of your coffee receipt, you have encountered Thailand’s Value Added Tax (VAT). First introduced in 1992 to replace the old business tax system, VAT is one of the primary pillars of Thailand’s tax revenue.

While the concept is straightforward, Thailand’s VAT system has a few unique quirks—most notably a “temporary” tax rate that has lasted nearly three decades. Here is a complete guide to how VAT works in Thailand.

1. The Current VAT Rate: Why 7% Instead of 10%?

Under the Thai Revenue Code, the statutory VAT rate is actually 10%. However, following the 1997 Asian Financial Crisis, the Thai government reduced the rate to 7% to stimulate economic recovery and ease the cost of living.

Every year or two, the Thai Cabinet issues a Royal Decree to extend this reduction. Under Royal Decree No. 807, the 7% rate remains in effect through September 30, 2027.

Behind the scenes, that 7% is split into two components:

• 6.3% goes directly to the central government (the Revenue Department).
• 0.7% goes to local administrative authorities as a municipal tax.

2. The Three Tiers of Thai VAT

Not every transaction is taxed at 7%. Thailand divides goods and services into three distinct categories:

Category	Rate	Who It Applies To	Input VAT Recovery
Standard Rate	7%	Most domestic sales of goods, provision of services, and imported goods.	Yes — businesses can reclaim VAT paid on business purchases.
Zero-Rated	0%	Exports of goods, services performed in Thailand but consumed abroad, and international transport.	Yes — exporters charge 0% to foreign clients while still reclaiming input VAT on local costs.
VAT-Exempt	N/A	Unprocessed agricultural products, education, healthcare, domestic transport, real estate leasing, and businesses under the revenue threshold.	No — exempt businesses do not charge VAT and cannot reclaim VAT paid on expenses.

3. Who Must Register for VAT?

Registration depends on gross annual turnover (total revenue before deducting expenses), not net profit:

• The 1.8 Million Baht Threshold: Any individual, partnership, or company supplying non-exempt goods or services in Thailand with annual revenue exceeding THB 1.8 million must register for VAT.
• The 30-Day Rule: Once your turnover crosses THB 1.8 million, you have 30 days to submit a VAT registration application (Form PP.01) to the Revenue Department.
• Foreign Digital Platforms (e-Service Tax): Foreign companies providing electronic services (such as streaming, software, or digital ads) to non-VAT-registered users in Thailand must also register and remit 7% VAT if their Thai revenue exceeds THB 1.8 million.
• Voluntary Registration: Businesses earning under THB 1.8 million are exempt from mandatory registration, but they can still register voluntarily. This is often a smart move for B2B startups that want to issue official tax invoices to corporate clients and reclaim VAT paid on equipment or inventory.

4. How VAT Calculation Works (Output vs. Input)

Thailand uses a standard credit-invoice system. As a VAT-registered business, you act as a collection agent for the Revenue Department:

$$\text{VAT Payable} = \text{Output VAT} – \text{Input VAT}$$

1. Output VAT: The 7% tax you collect from your customers on your sales invoices.
2. Input VAT: The 7% tax you pay to your suppliers on business-related purchases.

Example: Suppose your company sells goods worth THB 500,000 in a month, collecting THB 35,000 in Output VAT. During that same month, you purchase materials worth THB 200,000, paying THB 14,000 in Input VAT. You subtract the two and remit the net difference of THB 21,000 to the Revenue Department. If your Input VAT exceeds your Output VAT, you can carry the credit forward to the next month or apply for a cash refund.

(Note: To claim Input VAT, you must hold a valid, compliant Tax Invoice bearing your company’s exact registered name, address, and Tax ID. Simplified receipts do not qualify for corporate tax credits.)

5. Monthly Filing Deadlines and Compliance

Once registered, compliance is an ongoing monthly commitment:

• Form PP.30: Businesses must file a monthly VAT return using Form PP.30—even in months with zero sales or purchases.
• Paper Filing Deadline: Within 15 days following the end of the tax month.
• Online Filing (e-Filing) Deadline: Extended to the 23rd of the following month.

Failing to register on time or missing monthly filings can result in stiff penalties—including fines up to double the unpaid tax and a monthly surcharge of 1.5% on overdue amounts.

For Tourists: VAT Refunds at the Airport

If you are visiting Thailand rather than running a business, you don’t have to absorb that 7% on big purchases. Tourists staying fewer than 180 days in a calendar year can claim a VAT refund on luxury goods and retail purchases totaling at least THB 2,000 (including VAT) from stores displaying the “VAT Refund for Tourists” sign. Just remember to request a P.P.10 form at the store and get your goods inspected by Customs at the airport before checking your luggage.
