Key Takeaways
- US taxes are based on residency for tax purposes (substantial presence test), not immigration status or citizenship
- Most work visa holders who spend 183+ days in the US meet the 'resident alien' tax standard and pay taxes like US citizens
- Business income from a US LLC or corporation is subject to US federal income tax regardless of the owner's residency status
- Self-employment tax (15.3%) applies to net business income for sole proprietors and single-member LLC owners
- Non-citizen business owners should work with a CPA specializing in international taxation
Non-citizen business owners in the USA are subject to US federal income tax on their US-sourced business income. The specific rules depend on whether you are classified as a "resident alien" or "nonresident alien" for tax purposes — a critical distinction that is determined by your time in the US, not your citizenship or visa type.
Resident Alien vs. Nonresident Alien for Tax Purposes
Most work visa holders who spend significant time in the US are "resident aliens" for tax purposes, meaning they are taxed on worldwide income just like US citizens. You are a resident alien if you:
- Meet the Substantial Presence Test: Present in the US for at least 31 days in the current year AND 183 days total over the current and two prior years (using a formula), OR
- Hold a green card (LPR status)
If you don't meet either test, you are a nonresident alien and pay US tax only on US-sourced income — but at potentially higher withholding rates.
Tax Obligations by Business Structure
| Structure | Federal Tax | Self-Employment Tax | State Tax |
|---|---|---|---|
| Sole Proprietor (resident alien) | Ordinary income rates (10–37%) | 15.3% on net income | Varies by state |
| Single-Member LLC (resident alien) | Pass-through ordinary rates | 15.3% on net income | Varies by state |
| S-Corporation | Pass-through ordinary rates | Only on salary portion | Varies by state |
| C-Corporation | 21% flat corporate rate | No — corp pays employment taxes | State corporate tax |
Key Tax Filing Requirements
- Form 1040 (resident aliens) or Form 1040-NR (nonresident aliens) for personal income
- Schedule C for sole proprietors and single-member LLCs
- Form 1065 for multi-member LLCs (partnership return)
- Form 1120 for C-corporations
- Quarterly estimated taxes — self-employed non-citizens must pay estimated taxes quarterly (Form 1040-ES)
Getting an ITIN for Tax Filing
Non-citizens without an SSN need an ITIN (Individual Taxpayer Identification Number) for personal tax filing. Apply using IRS Form W-7. The ITIN is not a work authorization document — it is solely for tax compliance. Your business uses an EIN; you use an ITIN for personal tax returns.
Frequently Asked Questions
Your visa type affects your initial tax status, but the Substantial Presence Test based on days in the US is what ultimately determines residency for tax purposes. Most H-1B, E-2, L-1, O-1, and long-term TPS holders qualify as resident aliens. F-1 students are typically nonresident aliens for their first 5 years in the US.
Yes. Most states with income taxes require non-citizen business owners to file state returns on income earned in the state. States without income tax (Texas, Florida, Nevada, Wyoming, etc.) are popular for non-citizen businesses partly for this reason.
Business loans and advances are not taxable income — they are debt obligations. Revenue-based funding proceeds are not reported as business income; only the interest/fees are deductible business expenses. Proper accounting with a qualified CPA is essential to correctly categorize funding in your business books.
The Qualified Business Income (QBI) deduction (Section 199A) allows pass-through business owners to deduct up to 20% of qualified business income. Non-citizen resident aliens who operate pass-through businesses (LLC, S-corp if eligible) may be eligible for this deduction. Consult a CPA for your specific situation.
Failure to file required US tax returns can result in penalties, interest, and potentially a finding of tax fraud. For non-citizens, tax noncompliance can also affect immigration applications — green card and naturalization applications include questions about tax compliance. Always file even if you believe you owe nothing.
US tax residents (including most work visa holders) must report foreign bank accounts with over $10,000 through FBAR (FinCEN Form 114) and potentially Form 8938. Having a US business does not eliminate foreign account reporting requirements. Non-compliance carries severe penalties.
Yes. All ordinary and necessary business expenses are deductible regardless of the owner's immigration status. Deductions include rent, utilities, equipment, supplies, employee salaries, business insurance, and the cost of business capital (fees on revenue-based funding advances).
Strongly recommended. Non-citizen business owner taxation involves multiple layers: federal income tax, self-employment tax, state taxes, international reporting requirements, and treaty benefits that may apply. A CPA with international tax experience can identify deductions and credits specific to your situation while ensuring compliance.
