Non-Resident US LLC Tax Calculator (2026)
For non-US residents who own a US LLC. Estimates whether your LLC owes US federal tax and what you must file regardless.
Last updated:
Quick Answer: A non-resident-owned single-member US LLC generally owes no US federal income tax if it has no effectively connected income (ECI) — e.g. online services to non-US clients with no US presence. But it must still file Form 5472 + a pro-forma Form 1120 every year, or face a $25,000 penalty. You need an EIN (no SSN required); an ITIN only if you personally must file. BeginPulse’s free calculator estimates your US tax and filing duties in 30 seconds.
Non-Resident US LLC Tax Estimator
For non-US residents who form a US LLC (typically Wyoming or Delaware). This estimates whether your LLC owes US federal income tax — and what you must file regardless. Your home country still taxes you; this only covers US obligations.
Effective Connected Income (ECI) status: NO — generally not US-taxable
Mandatory annual compliance (regardless of tax owed)
- Estimated CPA prep cost~$1,500/yr
- FinCEN BOI reportFree, mandatory
- Form 5472 or 1065Annual
Key notes for your scenario
- Online services delivered to US customers from outside the US typically do NOT create a US trade or business under current IRS guidance.
- Pure SaaS / digital products / consulting delivered remotely is generally not ECI.
- Single-member LLC (disregarded entity): Must file Form 5472 + pro-forma 1120 annually. Penalty for missing: $25,000.
What this calculator does NOT cover
- Your home-country tax (CFC, GILTI-equivalent, dividend repatriation, etc.).
- State income tax (most states only tax in-state activity — Wyoming/Delaware non-resident LLCs usually owe nothing).
- Withholding agent obligations (FDAP, 1042-S filings).
- Treaty positions — must be claimed on Form W-8BEN-E with the LLC's withholding agent.
- FIRPTA (real property), branch profits tax, dispositions.
This is the most error-prone area in non-resident LLC tax. If your numbers are non-trivial, hire a CPA who specializes in US international tax (Form 5472, ECI determinations) — ~$1,500-$3,000/yr is well-spent insurance.
Frequently asked questions
Does a non-resident-owned US LLC owe US federal income tax?
It depends on whether the LLC has effectively connected income (ECI) — income from a US trade or business. Pure online services to non-US clients with no US presence usually have no ECI and therefore no US federal income tax. ECI triggers full US taxation under IRC §882.
What is ECI and how do I know if I have it?
Effectively Connected Income is income from a US trade or business — having US-based employees, US warehouses, US-located servers used for core operations, or a "dependent agent" who closes deals in the US. Selling digital services from abroad to US customers, by itself, does not create ECI under most analyses.
Do I still have to file anything if I owe $0?
Yes. Single-member foreign-owned LLCs must file Form 5472 + a pro-forma Form 1120 every year regardless of income. The penalty for missing this is $25,000 per form. See our Form 5472 Checker for details.
What about withholding tax on US-source income?
Non-ECI US-source income (FDAP — interest, dividends, royalties) is subject to 30% withholding unless reduced by a tax treaty. A W-8BEN-E lets your payors apply treaty rates. The calculator handles common treaty cases but does not replace a CPA for complex situations.
Do I need an ITIN or EIN?
You need an EIN for the LLC itself (file Form SS-4; no SSN required). You only need an ITIN if you personally have US tax filing obligations — many non-resident LLC owners do not, if there is no ECI.
