US Expat Tax in Singapore (2026)
Americans working in Singapore still owe US tax on worldwide income. This guide covers the Foreign Earned Income Exclusion ($132,900 for 2026), the Foreign Tax Credit (Form 1116), housing exclusion, and Self-Employment tax — with a $150,000 worked example.
FEIE vs Foreign Tax Credit in Singapore
There is no US-Singapore tax treaty. At typical expat salaries above S$200,000, the Foreign Tax Credit still usually beats the FEIE because Singapore's effective rate exceeds the US rate on the same income. But without a treaty, the treaty-based savings clauses and pension rules don't apply — plan for separate US and Singapore filings with FTC coordination.

Singapore income tax (for context)
Singapore resident income tax is progressive: the first S$20,000 is tax-free, rising through 2%/3.5%/7%/11.5%/15%/18%/19%/19.5%/20%/22% to a 24% top rate on income above S$1,000,000 (IRAS, effective YA 2024). CPF applies only to citizens/PRs.
Foreign Housing Exclusion — Singapore
The default housing exclusion cap is 14% of the FEIE limit ($18,606 for 2026), after subtracting the 16% base amount. Singapore is listed in the IRS annual high-cost city notice, which allows a higher per-city cap. Use the current year's notice (IRS Notice 2025-series) for the specific per-city dollar limit — these numbers change annually.
Frequently asked questions
Is there a US-Singapore tax treaty?
No. Unlike the UK, Canada, or Australia, the US has no bilateral income-tax treaty with Singapore, and no totalization (Social Security) agreement. That means no reduced withholding on US-source income for Singapore residents, no treaty-based pension rules, and no savings clause. Double taxation is managed through the Foreign Tax Credit rather than treaty articles.
Should I use the FEIE or FTC in Singapore?
At typical Singapore expat packages (S$200k+), the FTC usually produces a lower US tax because Singapore's progressive effective rate at that income exceeds the US effective rate on the same income. At salaries near the FEIE limit with low Singapore tax, the FEIE can still win. Model both methods; switching out of the FEIE triggers a 5-year re-election lockout.
Do I pay US Social Security on Singapore self-employment income?
Yes. There is no US-Singapore totalization agreement. Self-employed Americans owe the full 15.3% US SE tax on net earnings from Singapore, in addition to Singapore income tax. Singapore CPF does not apply to foreigners, so there is no local payroll-tax offset available.
Does Singapore qualify for a higher foreign housing exclusion?
Yes. Singapore appears on the IRS annual high-cost city table with one of the highest per-city limits globally. That matters because Singapore expat rents regularly exceed the default 30%-of-FEIE housing cap — use the Singapore-specific limit from the current year's IRS notice when computing Form 2555 housing exclusion.
How do I report my Singapore CPF or SRS on my US return?
Singapore CPF only applies to citizens and PRs — most US expats on Employment Passes do not contribute. If you do contribute (dual citizenship or PR status), CPF is not US-tax-advantaged: employer contributions are US-taxable income, and growth inside CPF may be annual-phantom-income. SRS contributions similarly are not deductible for US purposes. Report all foreign accounts on FBAR if the aggregate exceeds $10,000 and on Form 8938 if thresholds apply.
