They are different charges: GST is a government tax collected by a GST-registered business, while service charge is imposed by the restaurant under its own terms. GST is calculated on the amount after service charge is added. Whether you must pay the service charge depends on the agreement between you and the business, including the terms communicated before or during the purchase.
The short answer
GST and service charge are not two names for the same thing. GST is a 9% standard-rated consumption tax in Singapore. A restaurant that is GST-registered collects it and accounts for it to the Inland Revenue Authority of Singapore (IRAS). A service charge is a separate fee set by the restaurant; the government does not require food-and-beverage businesses to impose one.

Both can be payable on one transaction. When service charge applies, GST is generally charged on the total price including that service charge. In IRAS’s worked example, $100 of food and beverages attracts a 10% service charge of $10, then 9% GST on the $110 subtotal ($9.90), producing a $119.90 bill.
That example does not make 10% a statutory service-charge rate or mean every restaurant uses the same terms. The amount due in a particular case depends on the prices and conditions the restaurant presented and the agreement formed with the customer.

How the two charges differ
| Question | GST | Service charge |
|---|---|---|
| What is it? | A tax on taxable goods and services consumed in Singapore. | A business-imposed charge connected with the restaurant’s service. |
| Who sets it? | The GST rate is set under Singapore tax law. The current standard rate is 9%. | The restaurant sets the rate or amount and its conditions. |
| Who may collect it? | Only a GST-registered business may charge and collect GST. | Any restaurant may impose a service charge if its business terms provide for it; government approval is not what creates the charge. |
| How is it calculated? | On the taxable selling price, including service charge where service charge applies. | According to the restaurant’s stated method, often a percentage of food and beverage prices. |
| Is it automatically due? | It is due where a GST-registered business makes a taxable supply and the charge is properly applicable. | Payment depends on the agreement between the customer and the business. |
IRAS describes the distinction plainly: a service charge is “not required by the government but imposed at the discretion of these businesses.” That statement, made by IRAS Director of Corporate Communications Kelly Wee on 28 August 2024, addresses why one restaurant may add a service charge while another does not.
How a restaurant bill is calculated
Use the following sequence when the menu amount is stated before service charge and GST:
- Start with the food-and-beverage amount. In the IRAS example, this is $100.00.
- Add the service charge. A 10% charge on $100 is $10.00, giving a subtotal of $110.00.
- Calculate GST on that subtotal. Nine per cent of $110 is $9.90.
- Add GST to reach the amount payable. The total is $119.90.
In formula form, when both charges apply at those example rates:
menu amount × 1.10 × 1.09 = final amount
For a $100 menu amount, that is $100 × 1.10 × 1.09 = $119.90. The combined increase is 19.9% above the initial menu amount in this specific calculation. It is not a universal restaurant surcharge: the service-charge percentage, GST treatment of particular items, discounts, and the way prices are displayed can change the result.
Why GST is charged on service charge
GST applies to the final value of goods or services consumed, inclusive of service charge where there is one. Therefore, calculating 9% only on the original food price would understate the GST in a bill that includes a taxable service charge. The $9.90 in the example is based on $110, not $100.
Worked examples with different service-charge terms
| Food and beverages | Service-charge term | Service charge | GST base | 9% GST | Total |
|---|---|---|---|---|---|
| $80.00 | 10% | $8.00 | $88.00 | $7.92 | $95.92 |
| $120.00 | 5% | $6.00 | $126.00 | $11.34 | $137.34 |
| $100.00 | No service charge | $0.00 | $100.00 | $9.00 | $109.00 |
The table illustrates arithmetic only. It does not establish that any particular restaurant must use 5% or 10%, and it assumes the entire amount is taxable at the standard 9% rate with no discounts or other adjustments.
What “++” means on a Singapore menu
Restaurants and hotels sometimes show a price followed by “++”. In common usage, the first plus refers to service charge and the second to GST. The symbols alone are not a complete contract, however; read the accompanying wording for the actual rates and exceptions.

IRAS’s general rule is that GST-registered businesses should display and quote GST-inclusive prices to the public. A specific exception permits qualifying hotels and food-and-beverage establishments that impose service charge to display prices exclusive of GST. To use that exception, the business must prominently state that the displayed prices are subject to GST and service charge.
The exception is designed for operations in which, for example, dine-in attracts service charge while takeaway does not, or service charge may be waived in certain situations. It does not remove GST. When the service charge applies, GST remains chargeable on the final amount including that charge.
When the display exception does not apply
- A food-and-beverage establishment that does not impose service charge cannot rely on this particular exception to show GST-exclusive public prices.
- IRAS says the exception is also unavailable where a business levies only a nominal service charge, without genuine business reasons, to avoid displaying GST-inclusive prices.
- The notice about GST and service charge must be prominent. A customer should not have to infer the additional charges from an obscure footnote.
Price-display compliance is a matter between the business and the tax rules. It does not by itself decide whether a disputed service charge was agreed in an individual transaction. IRAS guidance describes a possible fine of up to $5,000 for price-display non-compliance; that is a potential business penalty, not an extra amount a diner must pay.
Reading a displayed price before you order
Do not rely on the menu number alone. First identify whether the menu says prices are inclusive of GST, subject to GST, or subject to both GST and service charge. A qualifying hotel or food-and-beverage business may use GST-exclusive public prices only with a prominent notice. A restaurant that does not impose service charge does not qualify for that particular GST-exclusive display exception.

1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteLook at the same notice for dine-in and takeaway. A business may have different treatment when service charge applies only to dine-in, while takeaway has no service charge. A set-menu quotation, private-room package, event booking or delivery arrangement can also contain its own price terms. Keep a copy or photograph if the wording is important, especially when the final bill will be shared among a group.
If a promotion says that service charge is waived, ask whether the waiver is already reflected in the quoted price or will appear as a separate line on the bill. The GST calculation should follow the actual amount payable after the applicable service-charge term is applied. If the wording is ambiguous, ask before ordering rather than waiting until payment.
Is service charge compulsory?
There is no Singapore rule requiring every restaurant to impose a service charge. A business may choose to impose one, set its percentage, waive it in some circumstances, or operate without one.
Once you are dealing with a particular restaurant, the more precise question is whether the charge formed part of the agreement for your meal. IRAS states: “Whether the customer should pay for the service charge depends on the agreement between the customer and the business on the price payable for the goods and services provided.”

The relevant evidence may include the menu, a displayed notice, online booking terms, a set-menu quotation, a banquet contract, and any explanation given before the order. A clearly disclosed charge that you accepted as part of the purchase is different from a fee first revealed after payment was agreed, but the facts of each transaction matter.
How to check a bill before paying
- Find the food-and-beverage subtotal. Check that the items and quantities match what you ordered.
- Look for the service-charge line. Note its percentage or fixed amount and whether it applies to all items, only dine-in items, or a particular package.
- Check the GST line. Where service charge is included, the GST base should ordinarily include it. Using the example above, a $110 subtotal produces $9.90 GST at 9%.
- Compare the bill with the price information you saw. Review the menu heading, table notice, reservation confirmation, or package quotation for wording such as “subject to GST and service charge.”
- Confirm the business’s GST status if needed. Only GST-registered businesses may charge and collect GST. IRAS provides a service for checking a business’s GST registration.
- Ask for clarification before payment when something is unclear. Request that staff explain the rate, the GST base, and the price terms that were shown to you.
Checking unusual or promotional bills
A service charge does not have to be a percentage, so check whether the restaurant stated a fixed amount, a percentage, or a package-specific rule. Recalculate using the restaurant’s stated method rather than assuming 10%. If the bill includes a discount, waived charge or excluded item, ask which amount was used as the GST base. The figures may differ from a simple menu-total calculation when the terms change the amount payable.
For a large group, compare the bill with the banquet or set-menu quotation. Confirm whether the quotation was GST-inclusive or subject to GST and service charge, whether a minimum spend was stated, and whether a promised waiver appears on the final bill. These checks do not decide a legal dispute, but they help identify whether the arithmetic matches the terms accepted for the booking.

What to do if you dispute the service charge
Start with the restaurant rather than assuming the issue is a tax calculation. Keep the receipt and, if possible, a photograph or copy of the menu and any sign showing the pricing terms. Explain precisely what you understood the price to be and ask the manager to identify where the service-charge term was disclosed.
Separate the questions:
- Was GST properly charged? Check whether the business is GST-registered and whether the tax was calculated on the correct taxable amount.
- Was the service charge part of the agreement? Check the communications and terms for that meal or booking.
- Was the arithmetic correct? Recalculate the percentage and confirm whether discounts or exclusions were applied before the charge.
IRAS guidance establishes the tax treatment and the general agreement principle, but it does not determine every individual contract dispute or promise a particular remedy. If the restaurant and customer cannot resolve the disagreement, obtain advice appropriate to the facts from a Singapore consumer or legal service. Do not describe a charge as unlawful solely because it is called a service charge, and do not treat a tax query as proof that the underlying agreement existed.
Rank #4
Common situations and how the answer changes
| Situation | What to examine | Likely calculation point |
|---|---|---|
| Dine-in menu marked “++” | The notice should explain that prices are subject to GST and service charge, and the stated service-charge rate should be identifiable. | Add the service charge first, then calculate GST on the resulting amount. |
| Takeaway from a restaurant that charges service charge only for dine-in | Check whether the takeaway price is treated separately and whether the displayed price is GST-inclusive. | If no service charge applies, GST is calculated on the applicable takeaway price. |
| Service charge waived by the restaurant | Confirm the waiver on the bill or written quotation. | With no service charge, it is not part of the GST base. |
| Restaurant with no service charge | Check the displayed price and GST wording. | There is no service-charge amount to add; GST still applies if the business is GST-registered and the supply is taxable. |
| Banquet, event, or set-menu contract | Read the quotation and signed or accepted terms, including minimum spend, fees, and waiver conditions. | Use the contract’s stated pricing structure rather than assuming the standard dine-in menu treatment. |
Questions customers often get wrong
“Does paying GST mean I do not have to pay service charge?”
No. GST and service charge have different legal and commercial bases. A bill can include both when the restaurant’s terms provide for service charge and the business is charging GST properly.
“Is the typical 10% service charge a government rate?”
No. IRAS describes 10% as typical in the sector, not mandatory. Restaurants may use different rates or no service charge, subject to how they communicate their prices and terms.
“Can a restaurant charge GST if it is not GST-registered?”
Only GST-registered businesses may charge and collect GST. If you are unsure, use IRAS’s GST-registration checking service and ask the business to clarify the tax line.
“Why did my bill rise by almost 20%?”
In the common example, a 10% service charge is added to the menu amount and 9% GST is then applied to the higher subtotal. The combined result is 1.199 times the original amount. That is the arithmetic of those two rates, not a universal surcharge for every restaurant.
“Can I refuse a service charge because it is discretionary?”
The government’s decision not to require restaurants to impose service charge does not answer whether you agreed to a particular restaurant’s charge. Review the disclosed terms and raise any uncertainty with the business.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Practical questions to ask staff
- Are the menu prices inclusive of GST, or are they subject to GST and service charge?
- What service-charge rate or fixed amount applies to this meal?
- Does the charge apply to takeaway, children’s items, set menus or only dine-in orders?
- Is a promotion or waiver already included in the quoted price?
- Is the restaurant GST-registered, and can the GST registration be verified through IRAS?
- Will the receipt show the service-charge amount and the GST amount separately?
These questions are especially useful when a menu uses “++”, when a reservation was made online, or when a group order has several packages. Getting the terms before ordering avoids relying on an assumption about what the symbols or a promotional headline mean.
Practical takeaway for diners
Before ordering, look for the restaurant’s price notice and whether it says prices are subject to GST and service charge. On the bill, identify the service-charge amount, then verify that GST is calculated on the subtotal including that charge when it applies. Remember that 9% GST is the tax rate, while 10% is only a typical service-charge example cited by IRAS. If the charge was not clearly communicated or the arithmetic appears wrong, ask for an explanation and retain the documents. The decisive issue for service-charge payment is the agreement with the business, not a blanket rule that every service charge is either compulsory or optional.

Frequently Asked Questions
Are restaurant service charge and GST the same charge?
No. GST is a 9% government tax collected by a GST-registered business. Service charge is a separate amount imposed under the restaurant’s own terms.
Do I pay GST on the service charge?
Generally, yes. When the service charge applies, GST is calculated on the total amount including that charge. IRAS’s example applies 9% GST to $110 after adding a $10 service charge to $100 of food.
Is a 10% service charge compulsory in Singapore?
No. IRAS describes 10% as typical, not mandatory. The government does not require every restaurant to impose a service charge.

Not automatically. Whether payment is due depends on the agreement between you and the business, including the menu, notices, booking terms and other pricing information communicated for the transaction.
What does “++” mean on a menu?
It commonly indicates that service charge and GST will be added to the displayed price. Read the accompanying notice for the actual rate and whether the price is GST-exclusive.
How can I check whether a restaurant may collect GST?
Only GST-registered businesses may charge and collect GST. Use IRAS’s GST-registration checking service or ask the restaurant to clarify its registration and tax line.
What should I do if the menu did not clearly mention service charge?
Keep the receipt and any menu or booking confirmation, ask the manager where the term was disclosed, and explain what price you understood you had accepted. The facts of the individual agreement matter.
Recommended Free Tools
Why is my total about 19.9% higher than the menu amount?
With a 10% service charge followed by 9% GST, the calculation is menu amount × 1.10 × 1.09, or 1.199 times the original amount. Those are example rates, not a universal restaurant surcharge.
The Bottom Line
GST is a 9% tax; service charge is a restaurant-imposed fee. Both may appear on the same Singapore bill, and GST is generally calculated after adding the service charge. The service-charge percentage is not set by government, and whether you must pay it depends on the price agreement and disclosures for your transaction. Check the menu wording, confirm the restaurant’s GST status when needed, and ask for an itemised explanation of any unclear charge.
