Thailand VAT Calculator (7%)

Value Added Tax (VAT) is a consumption tax levied on goods and services at each stage of production and distribution. Unlike a simple sales tax that is charged only at the final point of sale, VAT is collected incrementally at every step where value is added. Businesses registered for VAT collect the tax from customers and remit the difference between output VAT (collected on sales) and input VAT (paid on purchases) to the government.

Thailand introduced VAT on January 1, 1992, replacing the Business Tax system. The statutory rate is set at 10% under the Revenue Code, but a royal decree has kept the effective rate at 7% since 1999. This reduced rate has been continuously renewed by successive governments as a measure to support economic growth and keep prices affordable for consumers.

VAT is a major source of government revenue in Thailand, contributing approximately 25-30% of total tax collection. It is administered by the Revenue Department under the Ministry of Finance. Every VAT-registered business must display a VAT registration certificate (Por.Por.20) at their place of business.

Thailand's current effective VAT rate is 7%, consisting of 6.3% going to the central government and 0.7% allocated to local government organizations. Although the Revenue Code specifies a statutory rate of 10%, a royal decree has maintained the reduced 7% rate since October 1, 1999.

The Thai government periodically reviews this rate and has consistently extended the 7% reduction. As of 2026, there has been no change from the 7% rate. Any future adjustment would require a new royal decree or an amendment to the Revenue Code.

Additionally, Thailand applies a 0% VAT rate to exported goods and services and to services rendered in Thailand but utilized abroad. This zero-rating means exporters can still claim input VAT credits while not charging VAT to foreign buyers, keeping Thai exports competitive internationally.

Under Thai law, any person or business entity providing goods or services with annual revenue exceeding 1.8 million THB is required to register for VAT with the Revenue Department. This includes:

• Companies and partnerships registered in Thailand
• Sole proprietors and individuals conducting business
• Foreign businesses selling goods or providing services in Thailand
• E-commerce platforms and digital service providers selling to Thai consumers (since September 2021)
• Importers of goods into Thailand (VAT is collected by Customs at the point of import)

Businesses with revenue below 1.8 million THB may voluntarily register for VAT. This can be beneficial as it allows them to claim input VAT credits on business purchases, which may reduce overall costs. Once registered, a business must remain in the VAT system for at least 2 years.

VAT registration is done at the local Area Revenue Office where the business is located. Required documents include the company registration certificate, ID of directors, lease agreement for the business premises, and a map showing the business location.

Certain goods and services are exempt from VAT in Thailand under Section 81 of the Revenue Code:

• Unprocessed agricultural products: Fresh vegetables, fruits, meat, fish, and other unprocessed foods
• Animal feed and fertilizers: Feeds for livestock and agricultural fertilizers
• Newspapers, magazines, and textbooks: Printed educational and news materials
• Healthcare services: Medical treatment at government and licensed private hospitals (though private hospital fees may include VAT on non-medical services)
• Education services: Tuition at government and private schools/universities
• Domestic transportation: Bus, rail, and waterway transport (but not air travel, which is subject to VAT)
• Rental of immovable property: Residential and commercial property rent (but not hotel/serviced apartment stays shorter than 30 days)
• Financial services: Interest from deposits, life insurance premiums, and certain banking fees
• Government services: Fees and services provided by government agencies

Businesses that exclusively provide VAT-exempt goods or services cannot register for VAT and cannot claim input VAT credits. If a business provides both taxable and exempt supplies, it must apportion input VAT accordingly.

There are two common scenarios when calculating Thai VAT:

Worked Example 1: Adding VAT

Worked Example 2: Removing VAT

Worked Example 3: Service Invoice

A tax invoice (ใบกำกับภาษี) is the official document required for VAT purposes in Thailand. Every VAT-registered business must issue a tax invoice when selling goods or providing services to another VAT-registered entity. The tax invoice serves as proof that VAT was charged and allows the buyer to claim input VAT credits.

A valid tax invoice must contain the following information:

• The words "Tax Invoice" or "ใบกำกับภาษี" prominently displayed
• Seller's name, address, and 13-digit tax identification number
• Buyer's name, address, and tax identification number
• Sequential invoice number
• Date of issuance
• Description and quantity of goods or services
• Price before VAT, VAT amount, and total price including VAT

There are two types: the full tax invoice (ใบกำกับภาษีเต็มรูป) required for B2B transactions and input VAT claims, and the abbreviated tax invoice (ใบกำกับภาษีอย่างย่อ) allowed for retail sales to end consumers. The abbreviated version does not require the buyer's details.

Businesses must keep copies of all tax invoices issued and received for at least 5 years. Failure to issue proper tax invoices can result in fines of up to 2,000 THB per instance plus surcharges.

VAT-registered businesses must file a monthly VAT return using the PP30 form (แบบ ภ.พ.30). The filing deadline is the 15th of the month following the tax period. For example, VAT for January must be filed and paid by February 15.

Online filing through the Revenue Department's e-filing system (rd.go.th) grants an additional 8-day extension. This makes the effective deadline the 23rd of the following month for electronic filers.

The PP30 form requires the following information:

• Output VAT: Total VAT collected from sales during the period
• Input VAT: Total VAT paid on business purchases during the period
• Net VAT payable: Output VAT minus Input VAT (if positive, you pay the difference; if negative, you can claim a refund or carry forward)

Late filing penalties include a surcharge of 1.5% per month on the unpaid VAT amount plus fines ranging from 200 THB to 2,000 THB depending on the severity. Intentional evasion carries criminal penalties including imprisonment.

1. Always request tax invoices for business purchases. Without a valid tax invoice, you cannot claim input VAT credits, which means higher costs for your business.
2. Keep organized records of all purchase and sales tax invoices. Maintain a VAT ledger (purchase report and sales report) as required by law. This simplifies monthly PP30 filing and protects you during audits.
3. File on time every month, even if you have no transactions. A nil return (zero VAT) must still be submitted by the deadline to avoid penalties.
4. Understand input VAT restrictions. Not all VAT paid can be claimed as a credit. VAT on entertainment expenses, personal expenses, and certain vehicle-related costs is typically non-deductible. Consult the Revenue Department guidelines.
5. Consider voluntary registration even if below the 1.8M THB threshold. If your customers are VAT-registered businesses, they will prefer vendors who can issue tax invoices, allowing them to claim input VAT credits.
6. Use accounting software that handles Thai VAT automatically. This reduces errors in tax invoice generation and simplifies the monthly reporting process.
7. Plan for cash flow. VAT collected is not your revenue. Set aside collected VAT in a separate account to ensure you have funds available when the monthly payment is due.

• VAT calculations on this page are for reference purposes. For official business accounting, always use proper tax invoices and consult a licensed accountant.
• The 7% rate is maintained through a royal decree that is periodically renewed. While it has been in effect since 1999, it could theoretically change in the future.
• Import VAT is calculated on the CIF (Cost + Insurance + Freight) value plus any import duties, not just the purchase price.
• Digital services provided by foreign companies to Thai consumers have been subject to VAT since September 2021 under the e-Service rules.
