Washington LLC for Non-Residents: Tax Calculator (2026)

Form a Washington LLC as a non-US resident — 9/10 banking access, 5/10 privacy, 0% state income tax. Model your real US tax burden.

Washington ranks 9/10 on banking accessibility for non-resident-owned LLCs and 5/10 on member privacy. Washington's 0% personal income tax means non-resident owners with no Washington nexus owe no state income tax on LLC profits. Mercury, Brex, and most US business banks accept Washington LLCs owned by non-residents without distinction from US-resident-owned LLCs. Use the calculator below to estimate federal tax exposure and Form 5472 obligations.

See the complete non-resident US LLC guide, the Form 5472 filing checker, or the Washington LLC formation page.

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.

Estimated US federal tax$0

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.
