GST, VAT, SST — Understanding Consumption Taxes Across ASEAN
GST vs VAT vs SST: What Is the Difference?
GST (Goods and Services Tax) is effectively a VAT — a broad-based consumption tax collected at each stage of the supply chain, from manufacturer to retailer to consumer. At each stage, the seller charges tax on their output and claims a credit for tax paid on their inputs, so only the value added at each stage is ultimately taxed. Singapore calls it GST, New Zealand pioneered it under the same name, and the UK, EU, and Australia use the VAT label. The naming varies by country and political history, but the mechanics are nearly identical.
Malaysia briefly adopted GST in 2015 at 6%, but repealed it in September 2018 under the Pakatan Harapan government — a campaign promise that proved politically decisive. Malaysia replaced it with SST (Sales and Service Tax), which is a single-stage tax: sales tax is applied at the manufacturing or import level, while service tax applies at the point of service delivery. The net effect is simpler compliance for businesses, but less systematic input tax recovery. Indonesia calls its equivalent PPN (Pajak Pertambahan Nilai) — all are consumption taxes; the naming varies by country and political history.
Singapore's Journey from 7% to 9% GST
Singapore introduced GST at 3% in April 1994 — a bold move for a government known for fiscal conservatism. The rate climbed in stages: 4% in 2003, 5% in 2004, 7% in 2007, 8% on 1 January 2023, and 9% on 1 January 2024. Each increase was debated extensively in Parliament, with the government citing the rising cost of social services — particularly healthcare — for an ageing population.
GST is applied on most goods and services consumed in Singapore, but zero-rated on exports of goods and international services — meaning GST is charged at 0%, not exempted. This distinction matters: zero-rated suppliers can still claim input tax credits on their business expenses, whereas exempt suppliers cannot. The S$6.6 billion Assurance Package was introduced alongside the increase, providing direct cash transfers, GST vouchers, and utility rebates to cushion the impact on lower and middle-income households.
"Singapore raised GST to 9% in 2024 — funding the health and social infrastructure needed for a rapidly ageing population."
How ASEAN Countries Compare on Consumption Tax
ASEAN presents a diverse spectrum of consumption tax structures. The Philippines charges the highest standard rate in the region at 12% EVAT (Expanded Value Added Tax), introduced in 2006. Indonesia's PPN stands at 11% as of April 2022, raised from 10%, with the government targeting 12% subject to economic conditions. Singapore is at 9% GST, Vietnam and Cambodia at 10% VAT, and Thailand's 7% VAT has remarkably remained unchanged since 1997 — despite repeated government proposals to raise it to 10%.
Malaysia's picture is more complex: the 8% service tax (raised from 6% in March 2024) applies to a defined list of services, while sales tax of 5% or 10% applies at the manufacturing level. Myanmar levies a commercial tax at 5% on most goods and services. For businesses operating across ASEAN, the variation in rates, coverage, and compliance mechanisms creates significant complexity in cross-border transactions and transfer pricing.
For tourists, Singapore's Tourist Refund Scheme (TRS) offers an easy win: spend S$100 or more (including GST) at a participating GST-registered retailer, claim your refund electronically at Changi Airport on departure, and receive the GST back in cash or to your card. The scheme makes Singapore's 9% GST effectively optional for visitors on eligible purchases — a competitive advantage over neighbouring destinations that offer no equivalent. The S$1 million annual turnover threshold for mandatory GST registration is also notably high by international standards, shielding most small and micro businesses from compliance obligations.
10 Facts About GST and Consumption Tax in ASEAN
Singapore introduced GST at 3% in 1994 — raising it incrementally to 9% in 2024 over 30 years.
Malaysia replaced its 6% GST with the Sales and Service Tax (SST) in September 2018 — a political decision under the Pakatan Harapan government.
The Philippines has one of ASEAN's highest consumption tax rates at 12% VAT (E-VAT), introduced in 2006.
Thailand's 7% VAT has remained unchanged since 1997 — despite years of proposals to raise it to 10%.
Indonesia's PPN rate was raised from 10% to 11% in April 2022 — with plans to reach 12% subject to economic conditions.
Singapore tourists can claim a GST refund on purchases over S$100 at GST-registered shops through the Tourism Refund Scheme at Changi Airport.
Businesses with annual taxable turnover above S$1 million must register for GST in Singapore — a relatively high threshold by international standards.
Zero-rated supplies in Singapore include exports of goods and international services — meaning GST is charged at 0%, not exempted.
Singapore's Assurance Package provides S$6.6 billion in direct transfers and vouchers to offset the GST increase impact on lower-income households.
The "GST-inclusive" vs "GST-exclusive" distinction matters for businesses: contracts should specify which applies to avoid billing disputes.
Frequently Asked Questions
-
The current GST rate in Singapore is 9%, effective from 1 January 2024. It was raised from 8% (which applied during 2023) as part of a planned two-step increase to fund rising government expenditure, particularly healthcare for an ageing population.
-
To add 9% GST to $100: tax = $100 × 0.09 = $9; final price = $100 + $9 = $109. The formula is: Tax = Amount × (Rate ÷ 100); Final = Amount + Tax. Use the Add Tax mode in the calculator above for instant results.
-
To remove 9% GST from a GST-inclusive price, divide the total by 1.09. For example: $109 ÷ 1.09 = $100 (original price). Tax portion = $109 − $100 = $9. The formula is: Original = Total ÷ (1 + Rate/100). Use Remove Tax mode above.
-
Malaysia does not currently have GST. It replaced the 6% GST with SST (Sales and Service Tax) in September 2018. The service tax rate is 8% (raised from 6% in March 2024), and sales tax on goods is typically 5% or 10% depending on the item category.
-
Most goods and services in Singapore are subject to 9% GST. However, exports of goods and international services are zero-rated (0% GST, not exempt). Certain financial services and the sale or lease of residential properties are GST-exempt. Imported low-value goods are also subject to GST as of 2023.
-
Yes. Tourists can claim GST refunds through the Tourist Refund Scheme (TRS) at Changi Airport or Seletar Airport. You must spend at least S$100 (including GST) at a GST-registered retailer, depart within 2 months of purchase, and take the goods out of Singapore. The refund is processed electronically at the airport.
-
GST is a multi-stage tax collected at every stage of the supply chain — each business charges GST and claims credits for GST paid on inputs. SST is a single-stage tax — sales tax applies at manufacture or import, service tax applies at the point of service. Malaysia switched from GST to SST in 2018. SST is simpler for small businesses but provides less systematic credit recovery.
-
A business must register for GST in Singapore when its annual taxable turnover exceeds S$1 million. This is one of the highest thresholds globally, meaning most small businesses are exempt. Voluntary registration is also permitted for businesses below the threshold that wish to claim input tax credits.
-
Food from GST-registered restaurants, cafes, and supermarkets is subject to 9% GST. However, most hawker centre stalls and small food vendors are not GST-registered (they fall below the S$1 million threshold), so their prices do not include GST. Always check whether the establishment is GST-registered before assuming the tax applies.
-
The Philippines charges the highest standard consumption tax rate in ASEAN at 12% EVAT (Expanded Value Added Tax), introduced in 2006. Indonesia's PPN follows at 11%, then Singapore at 9% GST, Malaysia at 8% SST, and Thailand at 7% VAT. Vietnam and Cambodia are both at 10% VAT.
-
All preset rates are taken from each country's official tax authority and verified for 2026:
- Singapore — Inland Revenue Authority of Singapore (IRAS). 9% GST since 1 January 2024.
- Malaysia — Royal Malaysian Customs (Kastam Diraja Malaysia). 8% service tax since March 2024; 5% or 10% sales tax on goods depending on category.
- Thailand — Thailand Revenue Department. 7% VAT, unchanged since 1997.
- Indonesia — Directorate General of Taxes (DJP). Nominal PPN raised to 12% on 1 January 2025, but everyday consumption stays at an effective 11% via the DPP Nilai Lain 11/12 base — the full 12% applies only to luxury goods.
- Philippines — Bureau of Internal Revenue (BIR). 12% EVAT since 2006.
