Singapore’s government funds itself through a deliberately diversified mix: corporate and personal income taxes, a 9% goods and services tax, property levies and stamp duties, vehicle ownership fees, casino and betting duties, port and trade activity, high-value manufacturing, financial services, and tourism. On top of all that, roughly S$28.5 billion a year flows in from the returns on its sovereign wealth funds. So how does Singapore make money at the scale it does? For fiscal year 2026, operating revenue is projected at about S$134.8 billion, and the investment-return contribution pushes total resources to roughly S$163 billion. No single stream carries more than about a quarter of the total, which is the point.
Corporate and Personal Income Tax
Corporate income tax is the single largest operating revenue line, projected at S$37.8 billion for FY2026. Companies pay a flat 17% on chargeable income, and the same rate applies to local and foreign-incorporated businesses.1Inland Revenue Authority of Singapore. Corporate Income Tax Rates For Year of Assessment 2026, the government layered on a 40% corporate tax rebate capped at S$30,000 per company to ease cost pressure.2Inland Revenue Authority of Singapore. Corporate Income Tax Rate, Rebates and Tax Exemption Schemes Incentive programs run by the Economic Development Board, including the Pioneer Certificate and Development and Expansion Incentive, can pull the effective rate lower for firms making substantial local investments.3Singapore EDB. Incentives and Facilitation Programmes
The system is territorial. Income earned outside Singapore is generally untaxed unless remitted into the country, a principle set in the Income Tax Act 1947.4Singapore Statutes Online. Income Tax Act 1947 That rule is one of the main reasons multinationals base regional headquarters here.
Personal income tax brings in an estimated S$21.8 billion for FY2026. Rates are progressive, starting at 0% on the first S$20,000 of chargeable income and climbing through multiple brackets to a top marginal rate of 24% on income above S$1 million.5Inland Revenue Authority of Singapore.

Goods and Services Tax
The GST is a broad consumption tax now set at 9% on most goods and services consumed locally and on imports.8Inland Revenue Authority of Singapore. GST Rate Change for Consumers The rate rose from 7% in two steps, moving to 8% in January 2023 and to 9% in January 2024. GST is projected to yield S$22.3 billion in FY2026, the second-largest operating revenue source.
Because it taxes spending rather than income, GST captures money from tourists and residents alike and stays more stable across business cycles than corporate tax receipts. The legal framework sits in the Goods and Services Tax Act 1993.9Singapore Statutes Online. Goods and Services Tax Act 1993
Property Tax and Stamp Duties
Property-related levies bring in about a tenth of operating revenue. Asset taxes (annual property tax) are projected at S$7.3 billion for FY2026, with stamp duties adding another S$6.9 billion.
Annual property tax is progressive and is calculated from a property’s Annual Value, which approximates expected rental income. Owner-occupied homes start at 0% on the first S$12,000 of Annual Value and reach a maximum of 32% on the portion above S$140,000. Non-owner-occupied residential properties start at 12% on the first S$30,000 and climb to 36% above S$60,000.10Inland Revenue Authority of Singapore. Property Tax Rates The gap between the two schedules is deliberate, keeping the burden lighter on people living in their own homes.
Stamp duty applies on every purchase, and the Additional Buyer’s Stamp Duty is where Singapore stands out. Foreigners buying any residential property pay 60% ABSD on the higher of purchase price or market value. Corporate entities pay 65%.11Inland Revenue Authority of Singapore. Additional Buyers Stamp Duty (ABSD) Those rates, in place since April 2023, both raise revenue and dampen speculative demand.
Vehicle Ownership Revenue
Owning a car in Singapore is expensive by design, and the state collects at every stage. Vehicle Quota Premiums from the Certificate of Entitlement system are projected at S$9.4 billion for FY2026, with motor vehicle taxes adding another S$2.8 billion.
The COE system caps the total vehicle population by auctioning a fixed number of certificates in twice-monthly bidding exercises. In early 2026, a Category A COE (smaller cars) closed at roughly S$106,000. That premium only buys the right to register and use the vehicle for ten years. It does not include the car itself, the registration fee, or the Additional Registration Fee, which is a percentage of open market value. At the end of ten years, the owner either scraps the vehicle or pays to renew. The result is reliable revenue that doubles as a congestion tool on a land-scarce island.
Casino and Betting Taxes
Singapore’s two integrated resorts pay tiered casino taxes based on player type. For premium players (those depositing at least S$100,000), casinos pay 8% on the first S$2.4 billion of gross gaming revenue in a year and 12% above that. For all other players, the rates are 18% on the first S$3.1 billion and 22% beyond.12Inland Revenue Authority of Singapore. Casino Tax Rates Combined with betting duties on horse racing and lotteries, gambling-related taxes are estimated to yield S$3.8 billion for FY2026.
Returns on Sovereign Wealth Funds
This is the piece of Singapore’s revenue model that has no real parallel among developed economies. The Net Investment Returns Contribution, or NIRC, is budgeted at S$28.5 billion for FY2026. That single line exceeds personal income tax revenue and rivals the GST take.
The mechanism sits in Article 142 of the Constitution, which allows the government to spend up to 50% of the expected long-term real returns on the nation’s net assets.13Parliament of Singapore. Government Financial Statements for the Financial Year 2021/2022 Three entities manage those assets. GIC Private Limited runs long-term global investments across equities, bonds, real estate, and private markets. Temasek Holdings operates as an investment company holding stakes in major firms across technology, financial services, and industrials. The Monetary Authority of Singapore manages the country’s official foreign reserves, which stood at roughly US$409 billion in December 2025.14Monetary Authority of Singapore. International Reserves and Foreign Currency Liquidity
The 50% cap is the design that keeps the model sustainable. Drawing only half the expected returns preserves the principal for future budgets. The rate used to project those returns is set by the Minister for Finance and must be agreed by the President, a check that prevents any single government from spending down the reserves. Land sales flow into the reserves rather than into current spending, which grows the asset base further. In practical terms, NIRC gives Singapore a large endowment income that softens downturns and reduces pressure to raise tax rates.
The Port, Free Trade Zones, and Transshipment
The Port of Singapore sits on some of the busiest shipping lanes in the world, and much of what moves through it never enters the local economy in the ordinary sense. PSA International became the first terminal operator to handle more than 100 million twenty-foot equivalent units in a single year in 2024.15PSA International. About PSA International A large share of that volume is transshipment, meaning containers arrive from one country, briefly touch Singapore, and depart for another. The port captures handling, storage, and logistics fees from trade that is neither produced nor consumed locally.
Free Trade Zones extend that advantage. Under the Free Trade Zones Act 1966, goods stored or processed inside a designated zone are exempt from customs duties and GST as long as they stay outside the customs territory. Duties apply only when goods cross into the domestic market.16Singapore Statutes Online. Free Trade Zones Act 1966 Companies can consolidate cargo, repackage goods, and arrange onward shipment without triggering tax obligations they would face elsewhere. Around that core sit ship refueling, repair, brokerage, and marine insurance, along with port dues and pilotage fees.
High-Value Manufacturing
Manufacturing plays a larger role in Singapore’s economy than the country’s size suggests, concentrated in sectors where finished products command premium prices: semiconductors, medical devices, specialty chemicals, and refined petroleum. The pattern is consistent. Raw materials come in, precision manufacturing and quality control add value, and finished goods go out at margins that justify Singapore’s operating costs.
The Economic Development Board recruits global manufacturers with tax incentives and streamlined regulatory approval.3Singapore EDB. Incentives and Facilitation Programmes The petrochemical complex on Jurong Island processes crude oil into refined products and specialty chemicals for regional markets. Under the Enterprise Innovation Scheme running through YA 2028, companies performing qualifying R&D in Singapore can claim generous deductions on staff costs and consumables, which keeps advanced manufacturing from migrating to lower-cost neighbors.17Inland Revenue Authority of Singapore.

Financial and Professional Services
Financial services generate revenue through wealth management, foreign exchange, insurance, and banking for clients across Asia. The Monetary Authority of Singapore acts as both central bank and integrated financial regulator, overseeing banking, capital markets, insurance, and payments under a single framework.18Monetary Authority of Singapore. Regulation
Wealth management has been a particular growth engine. Singapore has become a preferred base for family offices managing the assets of ultra-high-net-worth families. Under the Section 13O fund tax incentive, family offices managing at least S$20 million in designated investments can qualify for tax exemptions on fund income if they meet minimum local spending requirements that scale with assets under management.19Monetary Authority of Singapore. Fund Tax Incentive Schemes for Family Offices The incentive trades tax revenue for local economic activity: hiring investment professionals, leasing office space, and engaging legal and accounting firms.
The foreign exchange market in Singapore ranks among the largest globally. Insurance companies sell risk products to multinationals operating across Southeast Asia. Tax revenue from financial institutions and the high-earning professionals they employ feeds back into the income tax figures above. Legal, accounting, and compliance expertise cluster around all of this, and each new firm makes the next arrival easier.
Tourism and Aviation
The Singapore Tourism Board projects 17 to 18 million international visitor arrivals for 2026, generating S$31 to S$32.5 billion in tourism receipts.20Singapore Tourism Board. Record Singapore Tourism Receipts from January to September 2025 That spending moves through hotels, restaurants, retail, and attractions, generating GST receipts, corporate profits, and taxable employment income.
Changi Airport is the infrastructure backbone. It handled a record 69.98 million passenger movements in 2025, up 3.4% from the year before.21Changi Airport. 2025 Operating Indicators Beyond passenger traffic, Changi runs extensive retail and dining operations inside its terminals, and its role as a regional connecting hub means every arrival represents international money entering the local economy.
Why the Mix Matters
Adding up FY2026: corporate income tax leads operating revenue at S$37.8 billion, followed by GST at S$22.3 billion and personal income tax at S$21.8 billion. Vehicle-related fees together contribute S$12.2 billion. Property taxes and stamp duties account for S$14.2 billion. The foreign worker levy adds S$7.5 billion. NIRC brings another S$28.5 billion from investment returns. No single source exceeds about a quarter of the total.
That balance is the whole strategy. When global trade slows and port activity dips, financial services and tourism may hold. When property markets cool and stamp duty falls, corporate tax and GST from a growing economy can offset the drop. Underneath everything, the sovereign wealth funds generate returns that are structurally independent of any one economic cycle. For a country with no natural resources and less land than most major metropolitan areas, the model works because the government runs its fiscal position the way an investment firm runs a portfolio: spread the risk, reinvest the returns, and avoid depending on any single bet.
