VAT in Thailand

VAT in Thailand

What is VAT?

VAT (Value Added Tax) is a sales tax applied to a wide range of goods and services in Thailand. 

If your home country uses GST then you can think of VAT as essentially the same, just a different name.

Whether VAT is charged is solely dependent on the seller and whether they have chosen to, or been required to, register for VAT.

Whether the buyer is registered for VAT has no impact on VAT being charged, but will affect the buyers ability to deduct the VAT paid as an expense.

Registering a Business for VAT

When a business first exceeds revenue (not profit) of over 1,800,000 THB per financial year,  the business must register for VAT. This must be completed within 30 days of exceeding this threshhold.

Optionally a business can choose to register for VAT before reaching this threshhold.
This would normally be done when they want to be able to claim back VAT, need to handle VAT on imports/exports, or another department such as Immigration expect VAT registration during another process.

To register for VAT you must complete form Por.Por.01 which would be submitted at the Revenue Department office which covers the businesses head office location.
If you operate under certain exempt activities then you should also complete form Por.Por.01.1

You will need the following:

  • Property rental contract of the business registered premises, with the name and address of the property owner or a consent letter for the properties business use.
  • ID card or passort of owners
  • Company registration documents, or partnership/fund/juristic, if applicable
  • Business licenses if applicable
  • Location map of business, with photos of building
  • Power of attorney form with stamp duty attached, assuming the business owner is not applying in person.

There is no fee payable for registering for VAT.

Calculating VAT on Invoices

The current VAT rate is 7% which is applicable on all items which are not otherwise excluded from VAT. You will find the list of excluded categories below.

VAT is simply calculated at the percentage rate of each items price.

Net PriceVAT 7%Gross Price
2,000 THB140 THB2,140 THB

This calculation would be common for B2B sales, where all parties are typically VAT registered so it is common for VAT to be added to the price.

However for consumer facing businesses it is far more common for prices displayed to already include VAT.

Some countries such as USA have normalised adding sales tax onto consumer prices. 
But in Thailand this is rare, outside of certain high end restaurants etc, where prices are sometimes displayed as ++ (+7% VAT and +10% service charge).

If you sell with VAT included you need to work out what amount would equal the final price when 7% VAT is added.
If you have a calculator handy simply divide the price by 1.07 to get the net price.

Gross PriceNet PriceVAT 7%
2,000 THB1869.16 THB130.84 THB

If you have multiple products at different tax rates in the same order it gets a little more complicated.
The VAT is calculated at each line level, then combined at the end for the final total.

VAT 0% Rate

In addition, certain activities have a VAT rate of 0%. While this sounds the same as being Exempt, there is a subtle difference.

For a 0% VAT activity there is no VAT charged on the sale. However the business is allowed to claim back VAT on any purchases directly related to the sale of the 0% goods.

For VAT Exempt products there is no VAT charged on the sale and the seller is prohibited from claiming VAT deductions on any purchases related to the sale.

The 0% VAT rate currently applies to:

  • Export of goods
  • Services rendered in Thailand and consumed outside Thailand in accordance with the rules, procedures and conditions prescribed by the Director-General
  • International transport services by aircraft or sea-going vessels
  • Sales of goods and services to Thai government ministries, departments or state enterprises under foreign loan assistance programs
  • Sales of goods and services to international organisations that Thailand is obliged under agreements with organisations to treat like embassies
  • Sales of goods and services to foreign economic and trade offices that are established in Thailand under agreements with foreign governments
  • Sales of goods or services between bonded warehouses and businesses located in export processing zones or duty-free zones

VAT on International Payments

In many cases VAT is not applicable on payments to overseas companies.

These sitautions are mostly listed above and fall under the 0% VAT rate.

A company exporting products overseasodes not need to charge VAT on their exports, but will need to pay VAT on related domestic purchases.

For services that are produced within Thailand and consumed outside Thailand there will be 0% VAT.

In some cases there may be foreign VAT applicable, depending on the overseas rules, but this is outside the scope of this article.

Monthly VAT Returns

VAT returns must be filed every month using form Phor Por 30 (PP 30 ภ.พ.30) or form Phor Por 36 (PP 36 ภ.พ.36).

This must be submitted and paid by the 15th of the month, for all transactions from the previous month.

Businesses with multiple branches must each submit their own VAT return, unless they have prior approval of the Director-General of the Revenue Department.

To submit the VAT return you will need to separately list and calculate the totals for the following.

  • Standard Taxable Sales
  • VAT 0% rate sales
  • VAT Exempt sales
  • VAT paid on purchases

Even though VAT 0% and exempt incur no VAT, it is still required to provide the totals of these transactions.

The VAT amount due is calculated as: 
VAT charged on VAT taxable Sales - VAT paid on taxable purchases.

So if you sold 100,000 THB (Net) of taxable products and bought 40,000 THB (Net) of taxable items your VAT due to be paid would be 4,200 THB (7,000 minus 2,800).
Even though you charged customers 7,000 THB of VAT you only need to pay the Revenue Department 4,200 THB because the other 2,800 THB has already been paid to other VAT registered businesses and will therefore be submitted by those suppliers.
This is where the name comes from, you only end up paying on the "Value Added" which is the difference of what you sold vs purchased.

It is also possible that you are entitled to a VAT refund if the VAT on your purchases is higher than the VAT on your expenses. This is most common for businesses operating in 0% VAT industries, but not in VAT exampt industries who are unable to claim on their purchases.

If you are entitled to a VAT refund you have 2 choices.
1) Roll VAT forward to the next month, where it can be offset against any VAT due, or rolled forward again if still a negative value.
2) Apply for a VAT refund which will be paid out by the Revenue Department.

If you do request a VAT refund to be paid out this may increase your risk of being audited by the Revenue Department. They are always happy to receive money but more careful when paying it out! 
So evaluate the risk/reward of this before proceeding, the cost and complexities of an audit could prove expensive if just a small amount owed. For larger companies already subject to yearly audits claiming VAT owed will be no issue.

Requirements of VAT Tax Invoices

One very important point to note is that you must have perfectly correct invoices and receipts from your suppliers in order to claim the VAT back on your purchases.

  • The Invoice must contain the words "tax invoice"
  • The Invoice must contain the name, address and taxpayer identification number of the supplier
  • The Invoice must contain the name and address of the purchaser
  • The Invoice must contain the date of issuance
  • The Invoice must contain the description, type, category, quality and value of the goods or services
  • The Invoice must contain the amount of VAT on the goods or services
  • The Invoice must contain the sequential number of the tax invoice

For the invoices that you generate for your customers it is also very important that the invoice numbers run sequentially. Any gaps in the invoice numbers will be perceived by Revenue Department as you trying to hide invoices and a suspect of Tax Evasion.
