## The short answer

If an offer adds a 10 percent service charge and then 7 percent VAT on the subtotal, multiply the "++" price by 1.177. A base rate of 1,000 becomes 1,177 under those assumptions. Check the offer's actual charge percentages, inclusions and other fees before you compare prices, and treat a figure worked out this way as an estimate: the provider's final checkout total for your dates, guests and room is the one to confirm.

* **The rule:** The two plus signs stand for a service charge and VAT (currently 7 percent) added on top of the base price. This guide's numbers assume a 10 percent service charge; check the rate the offer states.
* **Where:** You see this notation on hotel booking pages, restaurant menus, and spa price lists across the country.

## What "++" means

By law, Thailand's standard VAT rate is 10 percent, but the government periodically reduces it to 7 percent to stimulate spending. This current reduction runs until September 30, 2027 (Royal Decree No. 807, published in the Royal Gazette on 23 August 2026; checked 17 October 2026).

The ×1.177 figure assumes a 10 percent service charge and that the two additions compound rather than apply to the base price side by side: the venue adds the service charge to your base rate first, then calculates the 7 percent VAT on that new subtotal. You then pay tax on the service charge as well as on the room rate or your meal.

Knowing the calculation helps you budget and spot these charges before you pay. Here is the arithmetic on a base rate of 1,000, with a 10 percent service charge and 7 percent VAT:

* **Base price:** The advertised room rate or meal cost before the service charge and VAT is 1,000.
* **Plus 10 percent service charge:** The venue adds 100 directly to the base price to create a new subtotal of 1,100.
* **Plus 7 percent VAT:** The government calculates a 7 percent tax on the 1,100 subtotal, adding another 77.
* **The total:** With these two charges compounding, the total addition works out to 17.7 percent, making the total 1,177 before any other fees.

## Work it out

If an offer states a 10 percent service charge and 7 percent VAT on the subtotal, multiply the "++" price by 1.177. Enter the base price below; if the offer states a different service charge, enter that too. The calculator gives an estimate: the provider's final checkout total is the amount to confirm.

(An interactive table or map is on the web page: <https://trip4am.com/guides/thai-hotel-plus-plus-tax-explained/>.)

You can also do this math quickly on your phone calculator. Enter the base price, multiply it by 1.1, and then multiply that result by 1.07. This gives the same estimate for a 10 percent service charge and 7 percent VAT.

Sometimes you see a single plus sign instead of the usual double plus. This usually means the price includes the VAT but excludes the service charge, or vice versa. In those cases, you only apply the relevant percentage.

## Where you will see it

The "++" notation is standard across the Thai hospitality sector. You encounter it most frequently when booking accommodation or sitting down for a meal.

* **Hotel rates:** Many international booking platforms display the base rate in large text, while the taxes and fees sit in smaller print.
* **Restaurant menus:** Mid-range dining rooms, hotel bars, and beach clubs usually state at the bottom of the page if prices are subject to additions.
* **Booking sites:** Always check the final payment page closely, as some hotels add other local charges or city levies that sit outside the standard formula.
* **Villas and long stays:** Serviced apartments and resort villas run like hotels can add the same charges, while private rentals usually quote one monthly price, so ask which it is before you sign.
* **Where you usually will not see it:** Street food stalls, casual local restaurants, and independent operators on the street usually quote net prices.

Pick booking platforms that display "net" prices if you want to stick strictly to a daily budget without doing mental math on every search page.

Skip platforms that display "net" prices if you prefer to see how much of your money goes to the hotel versus the government.

## Comparing prices across sites

Comparing accommodation is frustrating when every website displays prices differently. Some lead with the base rate, others with the total. To compare like with like, compare the all-in prices for the same room, dates, guests and cancellation terms: the base rate plus the service charge, the 7 percent VAT and any other fees.

If a site only shows a pre-tax price and states a 10 percent service charge and 7 percent VAT, multiply it by 1.177 and treat the result as an estimate. A different service charge or other fees change the total, so confirm the provider's final checkout total for your dates, guests and room before you book.

Over busy holidays, compare more than the rate. Our [December guide](https://trip4am.com/guides/where-to-go-thailand-december-2026/) covers the holiday gala dinners and minimum stays to check for, and our [Songkran guide](https://trip4am.com/guides/songkran-2027-where-to-stay/) covers booking around mid-April.

> Tip: A price followed by the word "net" means the service charge and VAT are already included in the number you see; other fees, such as a city levy, can still apply.

## Frequently asked questions

### Is ++ included in prices on booking sites?
It depends on the platform and your location settings. Some sites show the base rate initially and only add the service charge and VAT at the final checkout screen. With a 10 percent service charge and 7 percent VAT, that is 17.7 percent on top; the checkout total is the figure to confirm.

### Do I still need to tip?
You don't need to leave an additional tip if a venue applies a 10 percent service charge. The staff shares this charge, though leaving loose change is common for exceptional service.

### Can tourists claim the VAT back on hotel bills?
No, the VAT refund for tourists only applies to goods purchased at participating retail shops that you take out of the country. You can't claim back the VAT spent on accommodation or meals.

### Is the service charge compulsory?
Expect to pay it when it is shown clearly. In October 2022 Thailand's Office of the Consumer Protection Board said a restaurant may collect a service charge only when it displays the charge clearly, and that customers can refuse to pay one that was not displayed. For a hotel, the booking conditions state its charges; check them before you book.
