Facebook ads in Thailand run in Meta Ads Manager, and Meta adds VAT to your bill unless you add your VAT ID to the ad account. You can pay by card, PayPal or in-app bank transfer, or by PromptPay, TrueMoney or KBank KPlus if you chose a local method when you set up the account.

## Facts that differ in Thailand (checked 2026-10-20)

| Fact | Thailand |
|---|---|
| Ad transparency | The [Meta Ad Library](/glossary/meta-ad-library) shows every active ad ([Meta](https://www.facebook.com/business/help/2405092116183307)). Thailand is on Meta's list of countries where ads about elections or politics need authorisation and a disclaimer. For Thailand, only the name on the disclaimer is shown on those ads ([Meta](https://www.facebook.com/business/help/2150157295276323)). |
| Tax on Meta's bill | Since September 2021, Meta adds VAT if your "Sold To" address is in Thailand and you have not added a VAT ID. With a VAT ID added, Meta adds none, and you pay VAT yourself under the reverse charge ([Meta: Thailand VAT](https://www.facebook.com/business/help/562800201396939)). The Revenue Department says the rate is 7 percent ([Revenue Department](https://www.rd.go.th/english/6043.html)). |
| Main languages | Thai is the official language ([Thai government portal](https://www.thailand.go.th/page/thai-language)). |
| Popular platforms | Ad reach in late 2025: TikTok 56.6 million (adults only), Facebook 51.5 million, YouTube 47.2 million, Instagram 20.6 million. LINE, a chat app, reports 56 million monthly active users ([DataReportal](https://datareportal.com/reports/digital-2026-thailand)). Ad reach is the audience each platform's ad tool reports, not active users. |
| Payments and currency | In-app bank transfers, Amex, Mastercard and Visa cards, PayPal, and the manual methods KBank KPlus, PromptPay and TrueMoney. Manual methods need Thailand as the account country and baht as the currency, and you must choose one when you first set up the ad account ([Meta](https://www.facebook.com/business/help/1599220466776406)). The baht is on Meta's list of [accepted currencies](https://www.facebook.com/business/help/151451521590943). |
| Time zone | UTC+7 all year, no daylight saving ([IANA tz database 2026e](https://www.iana.org/time-zones)). |

## Key selling dates (checked 2026-10-20)

- **Black Friday:** Friday 27 November 2026 ([plan](/campaigns/black-friday-ad-ideas)).
- **National Day and Father's Day:** the holiday is Monday 7 December 2026, a substitute day ([Thai mission list](https://unmissionnewyork.thaiembassy.org/en/content/official-holidays-2026)).

- **Songkran:** 13 to 15 April every year ([Thai government portal](https://www.thailand.go.th/issue-focus-detail/001_02_250)).

## What to run and when

Say you spend THB 100,000 on ads and have not added a VAT ID. At 7%, Meta adds THB 7,000 and you pay THB 107,000. Add a VAT ID and Meta adds nothing, and you account for the THB 7,000 yourself. Ask your accountant which route suits you.

Thailand is a large market, with Facebook reaching 51.5 million, so you have room to test several creatives at once. Start your tests in the week before Black Friday and put the budget behind the winners for the December holidays. Selling across the region? Compare [Vietnam](/markets/meta-ads-in-vietnam), [Malaysia](/markets/meta-ads-in-malaysia) and [Singapore](/markets/meta-ads-in-singapore).

To see what rival brands run before you spend, search the Ad Library by hand. We make Marxx, which [tracks competitor ads](/features/competitor-tracking) on Meta and Google in one place.

## Common mistakes

- Leaving VAT out of the budget. Meta adds it on top unless you add a VAT ID.
- Planning on PromptPay or TrueMoney without choosing it when you first create the ad account in baht with Thailand as the country.
- Running ads about elections or politics without authorisation.
- Ignoring LINE when you plan follow-up. It reports 56 million monthly active users in Thailand.
