Quick answer: Yes, a US citizen or green card holder can own 100% of a Singapore private limited company with no local partner required. The catch is not Singapore’s rules — it’s that the US taxes citizens on worldwide income regardless of residence, and there is no comprehensive US–Singapore income tax treaty. Owning ≥10% of a Singapore company as a US person triggers Form 5471, FBAR (if aggregate foreign accounts exceed US$10,000), possibly Form 8938, and from tax years beginning after 31 December 2025, the old GILTI regime is replaced by Net CFC Tested Income (NCTI) at roughly a 12.6% effective rate. None of this is a reason not to incorporate in Singapore — it’s a reason to loop in a US-qualified CPA before you do.
TL;DR:
- 100% US ownership of a Singapore company is fully permitted — no local shareholder or director nationality restriction on ownership itself (a locally resident director is still required, but need not be a US or Singapore citizen).
- There is no general US–Singapore income tax treaty — only a narrow shipping/aircraft agreement. No treaty-based relief exists for most cross-border income.
- US persons owning ≥10% of the Singapore company must file Form 5471 annually with their US return.
- FBAR is required if aggregate value of foreign financial accounts (including the company’s bank accounts, if you have signature authority) exceeds US$10,000 at any point in the year — filed separately via FinCEN, not attached to your tax return.
- Starting tax years after 31 December 2025, GILTI is renamed Net CFC Tested Income (NCTI), with the effective rate rising from roughly 10.5% to roughly 12.6% and the QBAI exclusion eliminated.
- Depending on your facts, Forms 8938, 8858 or 8865 may also apply — this is a US-side compliance question, not a Singapore incorporation question, and needs a US CPA who handles international filings.
Yes. Singapore places no restriction on foreign — including US — ownership of a private limited company. Like any foreign founder, a US person still needs at least one director who is ordinarily resident in Singapore (a Singapore citizen, permanent resident, or Employment Pass holder), a registered local address, and a company secretary appointed within six months of incorporation. None of these requirements are US-specific — they apply to any foreign-owned Singapore company.
Singapore has double tax agreements with over 100 countries. The United States is not meaningfully one of them — the only bilateral tax accord between the two is a limited agreement covering international shipping and aircraft income, not a general income tax treaty. This matters for two reasons.
First, there is no treaty-based reduction on withholding taxes or tie-breaker residency rules to fall back on if income could be taxed by both countries. Second, and more specific to US persons: the US taxes citizens and green card holders on worldwide income regardless of where they live or where the money is earned — a rule almost no other country applies. A Singapore company’s profits are not automatically shielded from US tax just because Singapore itself has attractive rates; foreign tax credits and the anti-deferral regimes below govern how much US tax is actually owed.
| Form | Triggered by | Filed |
|---|---|---|
| Form 5471 | US person owning ≥10% of a foreign corporation (most Singapore Pte. Ltd. structures) | Attached to your annual US income tax return |
| FBAR (FinCEN 114) | Aggregate value of foreign financial accounts > US$10,000 at any point in the year, including company accounts where you have signature authority | Separately via FinCEN’s BSA E-Filing System |
| Form 8938 (FATCA) | Specified foreign financial assets above a threshold that varies by filing status and US residency | Attached to your US income tax return |
| Form 8858 | US person owns a foreign disregarded entity (relevant for certain single-member structures) | Attached to your US income tax return |
| Form 8865 | US person is a partner in certain foreign partnership structures | Attached to your US income tax return |
Penalties for missing Form 5471 or FBAR are steep and apply per form, per year, even when no tax is ultimately owed — this is a filing obligation independent of whether the company made a profit.
For tax years beginning after 31 December 2025, the Global Intangible Low-Taxed Income (GILTI) regime is renamed Net CFC Tested Income (NCTI). Under the new rules, the Qualified Business Asset Investment (QBAI) exclusion is eliminated and the Section 250 deduction drops to 40%, pushing the effective US tax rate on this category of foreign income from roughly 10.5% up to approximately 12.6%. The downward attribution rule, previously repealed, also returns. If you are filing a 2025 return during 2026, the prior GILTI rules still apply for that filing year — the change takes effect for income earned in tax years starting after the 2025 year-end, not for the 2026 filing season itself.
Singapore taxes companies at a headline 17% corporate rate on Singapore-sourced income (with partial exemptions on the first S$200,000 of chargeable income for qualifying companies), and does not tax foreign-sourced income that is not remitted into Singapore. The US, separately, taxes the US shareholder on their share of the company’s income under Subpart F and NCTI/GILTI rules, generally allowing a foreign tax credit for Singapore tax already paid to reduce double taxation — but the credit calculation is its own area of complexity, particularly interacting with NCTI’s reduced deduction. The two systems run in parallel rather than being coordinated by a treaty, which is exactly why the compliance burden falls more heavily on US persons than on founders from most other countries.
The most common: treating Singapore incorporation as a purely local decision and only discovering the Form 5471 and FBAR obligations at US tax filing time, sometimes a full year after the company was set up — by which point a filing deadline may already be missed. The second: assuming Singapore’s 17% headline rate, or a tax exemption scheme, is the end of the tax analysis, when the US side of the calculation (Subpart F, NCTI, foreign tax credit limitations) is frequently the larger determinant of total tax owed. The third: not looping in a US CPA who specifically handles Form 5471 and international filings — this is a specialist area, and generalist US tax preparers routinely under-file or mis-file these forms.
VIVOS handles the Singapore side: incorporation, corporate secretary, registered address, nominee director arrangements, and banking introductions. Ray Tay, Co-Founder and Managing Director of VIVOS, is direct about the boundary: “We get the Singapore entity right — structure, filings, compliance calendar. We are not a US CPA firm and we don’t file Form 5471 or FBAR for clients. What we do is flag the US-side triggers early and make sure a client’s US advisor has everything they need from the Singapore side, so nothing falls through the gap between two systems that don’t talk to each other.”
If you don’t yet have a US CPA who handles international/foreign corporation filings, get one before incorporating — not after.
VIVOS incorporates Singapore companies for US founders every year and coordinates cleanly with your US tax advisor on timing and documentation.

December 2025); IRS guidance on FBAR (FinCEN Form 114) and Form 8938; One Big Beautiful Bill Act provisions renaming GILTI to Net CFC Tested Income (NCTI) for tax years beginning after 31 December 2025; IRAS list of DTAs, Limited DTAs and EOI Arrangements (confirming no comprehensive US–Singapore income tax treaty exists, only a limited shipping/aircraft agreement); ACRA company incorporation requirements. This guide is general information, not US or Singapore tax advice — confirm your specific filing obligations with a US-qualified CPA experienced in foreign corporation reporting.
No treaty exists to rely on. Relief from double taxation for US persons instead comes primarily through the US foreign tax credit mechanism, which offsets US tax on the same income against tax already paid to Singapore — but the credit is subject to its own limitations and does not always eliminate double taxation entirely, especially once NCTI’s reduced deduction is factored in.
Penalties start at a fixed dollar amount per form per year and can increase substantially the longer the form remains unfiled, independent of whether any US tax was actually owed. The IRS does offer voluntary catch-up filing procedures for taxpayers who missed prior years non-willfully — a US CPA experienced in international filings can advise whether you qualify.
No. Singapore corporate tax (17% headline, with exemptions) is what Singapore charges the company. NCTI (formerly GILTI) is a separate US tax charged to the US shareholder on their share of the foreign company’s “tested income,” layered on top of — not instead of — Singapore tax, with a foreign tax credit intended to reduce the overlap.
No. VIVOS handles Singapore incorporation, corporate secretary and compliance. Form 5471, FBAR, Form 8938 and related US filings must be handled by a US-qualified CPA. VIVOS can flag the triggers and supply the Singapore-side documentation your US advisor will need.
This is a structuring decision with real consequences for how NCTI and Form 5471 apply, and it should be made with a US CPA before incorporation — there is no single correct answer that applies to every founder’s situation.
