Thailand VAT Threshold 2026: The 1.8 Million Baht Rule Every Business Owner Must Know

A Bangkok cafe earning 1.5 million baht a year operates comfortably without VAT. An import company brings in 2 million baht in revenue but nets only 100,000 baht in profit, and it is legally required to register. One number separates the two, and the consequences could not be more different.

Thailand's Value Added Tax (VAT) system is unforgiving in one key respect: it taxes gross turnover, not profit. Many foreign entrepreneurs, especially those new to the Thai market, confuse revenue with net income, and that mistake can trigger penalties or force a business to a standstill.

Here is exactly who needs to register for VAT, how turnover is calculated, and what to do if you have already crossed the threshold.

Quick Answer

• The VAT registration threshold in Thailand is 1.8 million baht in annual turnover (roughly 50,000 USD)

• Turnover is measured as gross receipts from sales, with no deduction for expenses

• Registration is mandatory before starting operations or within 30 days of crossing the threshold

• The standard VAT rate in Thailand is 7% (a temporary reduction from the base rate of 10%)

• Foreign companies providing services in Thailand must also register once they exceed the threshold

• Exporters benefit from a zero VAT rate, while importers pay VAT at customs regardless of their registration status

Key Facts

• The calculation basis is annual turnover, meaning gross receipts. Costs for suppliers, rent, and salaries are never deducted. A company with 2 million baht in turnover and only 100,000 baht in profit must register exactly like a company earning 500,000 baht in profit on the same turnover

• The 1.8 million baht threshold is set by Royal Decree and applies to every legal entity supplying goods or services within Thailand

• Small businesses below the threshold qualify as a 'Small Entrepreneur' and are exempt from mandatory VAT registration, though voluntary registration remains an option

• International transactions do not exempt a business from VAT. If a Thai company arranges procurement in China for a European client and receives payments exceeding 1.8 million baht, registration is required

• 30 days is the maximum window to file a registration application once turnover crosses the threshold. Missing this deadline triggers penalties

• Import VAT is charged automatically by the Customs Department at the point of entry, regardless of whether the importer is VAT-registered

• Voluntary VAT registration allows a business to claim input tax credits on purchases and expenses, which can be more advantageous than operating VAT-free

• For property buyers specifically, VAT at 7% applies to new units sold by a juristic entity: on a 5 million baht unit this can add roughly 350,000 baht if VAT is not already built into the developer's quoted price, a distinction international buyers frequently overlook

How to Start: Step by Step

1. Calculate your annual turnover correctly. Add up every sales receipt over 12 months. Do not subtract expenses, cost of goods, or agent commissions. If the figure is approaching 1.8 million baht, start preparing for registration now

2. Identify your business category. Certain services are exempt from VAT by law, including medical services, education, domestic transport, and residential property rental. The full list appears in Section 81 of the Revenue Code

3. Prepare your documents for the Revenue Department. You will need company incorporation documents (DBD registration), an office lease agreement, directors' passports, a location map to the office, and photos of the premises. Applications are submitted via Form VAT 01

4. File within the required deadline. New businesses must register before starting operations. If turnover exceeds the threshold mid-operation, you have 30 days. Applications are filed at the district Revenue Department office where your company is registered

5. Set up VAT-compliant bookkeeping. Once registered, you must issue tax invoices, maintain an input and output VAT ledger, and file a monthly VAT return (Form PP 30) by the 15th of the following month

6. Hire an accountant experienced with Thai VAT. Managing this alone as a foreign business owner is a fast route to costly errors. Bookkeeping services for a small VAT-registered business typically start at 8,000-15,000 baht per month

7. Consider voluntary registration even below the threshold. If your clients are corporate entities, being VAT-registered strengthens your business credibility and lets you reclaim input tax on purchases

FAQ

What is the VAT registration threshold in Thailand in 2026?

The threshold is 1.8 million baht in annual turnover (around 50,000 USD). This includes all sales receipts, with no deduction for expenses.

Is turnover for VAT purposes based on profit or revenue?

Only revenue (gross receipts) counts. If a company receives 2 million baht but spends 1.9 million, turnover is still 2 million. Profit has no bearing on the registration requirement.

Does a foreign company need to register for VAT in Thailand?

Yes, if the foreign company supplies goods or services within Thailand and its turnover exceeds 1.8 million baht. This also applies to e-services.

What is the penalty for late VAT registration?

The Revenue Department can impose a fine equal to double the unpaid tax, plus a surcharge of 1.5% per month. Serious cases can carry criminal liability.

Can a business register for VAT voluntarily below the 1.8 million baht threshold?

Yes. Voluntary registration makes sense if your counterparties are themselves VAT-registered. You can then issue tax invoices and claim input tax credits.

What VAT rate applies in Thailand?

The base rate is 10%, but a temporary reduction to 7% has been in effect since 1992. This 'temporary' measure keeps getting extended every few years.

Do exporters pay VAT in Thailand?

Exporters apply a zero VAT rate (0%). They do not charge tax on export sales but can still reclaim input VAT on their purchases.

How often must a VAT return be filed?

The return (Form PP 30) is filed monthly, by the 15th of the month following the reporting period. Electronic filing extends the deadline to the 23rd.

Is property rental exempt from VAT?

Rental of residential property is VAT-exempt. Rental of commercial premises is subject to the standard 7% VAT rate if the landlord is VAT-registered.

VAT registration in Thailand is not a matter of preference, it is a matter of arithmetic. Calculate your gross receipts, compare them against the 1.8 million baht threshold, and act within the 30-day window. Delay costs far more than a timely conversation with a specialist accountant.
