Compare taxes and see how much you save moving from Texas to Singapore
Texas residents pay $0 in state income tax while Singapore residents pay approximately $9,000 in income tax at $100,000 USD — one of the lowest income tax burdens of any developed economy in the world. Texas and Singapore are arguably the two most tax-competitive jurisdictions in their respective contexts: both have no state/national income tax below certain thresholds and minimal rates above. However, US federal income tax (~$17,400 at $100K) applies to American Texans regardless of state policy, while non-Americans in Singapore pay only the $9,000 — making Singapore dramatically cheaper than Texas for non-US citizens. For Americans, Singapore's tax advantage over Texas requires FEIE optimization to realize.
No State Income Tax
Constitutional prohibition on state income tax — Texas residents pay no state-level personal income tax.
Low Progressive Tax
Progressive income tax from 0% to 24% — among the lowest effective income tax rates of any developed economy globally.
At $100,000 income:
Singapore's income tax is approximately $9,000 at $100,000 USD — one of the world's lowest tax rates for a developed economy. Texas has $0 state tax, but US federal applies to Americans everywhere. Both Texas and Singapore are extremely competitive on tax; Singapore wins for non-Americans who can eliminate US federal obligations.

Transfer Money Internationally →Yes — American citizens owe US federal income tax on their worldwide income regardless of residence in Singapore. Critically, there is no comprehensive US-Singapore income tax treaty, so Americans cannot use a foreign tax credit for Singapore taxes in the same way they would with treaty countries. Instead, Americans in Singapore primarily rely on the Foreign Earned Income Exclusion (FEIE, Form 2555) — which excludes up to $126,500 of foreign-earned income from US federal tax in 2025. For Americans earning below the FEIE limit, the US federal tax bill can be effectively eliminated. For higher earners, the excess above the FEIE limit is taxed at US rates. FBAR reporting for Singapore bank accounts is required.
Singapore's income tax is among the lowest in the developed world. At $100,000 USD income, the Singapore tax is approximately $9,000 — an effective rate of about 9%. Compare this to Germany ($28,000), Australia ($23,000), Canada/Ontario ($24,385), or Ireland ($39,000) at the same income. Even countries considered low-tax, like Portugal under IFICI (20%), cost more than Singapore. Singapore achieves this through a deliberately competitive tax policy designed to attract global business, finance, and talent. The top rate of 24% does not apply until Singapore income exceeds SGD$1 million (approximately $750,000 USD), making Singapore's progressive system extremely shallow by international standards.
The Central Provident Fund (CPF) is Singapore's mandatory social security savings system. CPF contributions are required for Singapore citizens and Permanent Residents (PRs) only — foreigners on Employment Passes (EP), Personalized Employment Passes (PEP), or EntrePass are generally not subject to CPF. At standard working ages, CPF contributions are 20% (employee) and 17% (employer) of gross wages. Since most American expats in Singapore hold Employment Passes rather than PR status, they are typically exempt from CPF contributions — meaning their entire compensation is net of CPF, which is a significant financial advantage compared to Singapore citizens. This exemption further enhances Singapore's attractiveness for foreign professionals.
No — as of 2026, the United States and Singapore do not have a comprehensive bilateral income tax treaty. This means US citizens in Singapore cannot use the foreign tax credit mechanism (which requires a tax treaty or the general foreign tax credit rules to credit Singapore taxes against US liability). Since Singapore's tax rates are low (9% effective at $100K), the amounts involved are modest — but Americans in Singapore cannot reduce their US tax bill by crediting Singapore taxes as easily as they could with treaty-country taxes. The primary tool for Americans in Singapore is the Foreign Earned Income Exclusion (FEIE), which can shield up to $126,500 of earned income from US federal tax if the physical presence or bona fide residence test is met.
Singapore attracts a diverse range of American professionals from Texas and other US states. Finance and trading professionals are drawn to Singapore's position as Asia's premier financial hub — home to major banks, hedge funds, commodity trading firms, and private equity operations. Technology professionals are attracted by the growing tech ecosystem, government digital initiatives, and regional headquarters of major US technology companies. Energy professionals — particularly relevant from Texas — are drawn by Singapore's role as the world's third-largest oil trading center and refining hub. Entrepreneurs and business owners value Singapore's ease of doing business (consistently ranked top 3 globally), low corporate tax rates (17%), and strategic location for accessing Southeast Asian markets.
Yes — Americans in Singapore who meet the IRS Physical Presence test (330 days outside the US in a qualifying 12-month period) or Bona Fide Residence test can claim the Foreign Earned Income Exclusion (FEIE) under IRS Form 2555. The 2025 FEIE exclusion is $126,500, indexed for inflation annually. For a Texan earning $100,000 in Singapore, FEIE can potentially eliminate the entire US federal income tax bill (approximately $17,400) on that income — since $100,000 is well below the $126,500 exclusion limit. Combined with Singapore's low income tax ($9,000), a Texan in Singapore could achieve a dramatically lower total income tax burden than staying in Texas. The key requirement is establishing genuine Singapore residency and maintaining the physical presence day count.
Singapore is one of the world's most expensive cities, particularly for housing and international schooling. A typical expat-standard two-bedroom apartment in Singapore costs SGD$4,000-$8,000 per month ($3,000-$6,000 USD) — significantly more than comparable accommodation in Houston, Dallas, or San Antonio. International school fees for children run $20,000-$40,000 per year. Vehicles are extraordinarily expensive due to Singapore's Certificate of Entitlement (COE) system — many expats opt not to own cars and use public transit instead. Dining and groceries range from very cheap at hawker centers (the famous local food courts) to expensive at Western-standard restaurants and supermarkets. Overall, Singapore's higher living costs partially offset its remarkable income tax advantage, particularly for families with children in international schools.
