Delaware LLC tax guide: federal, state, and Form 5472 for non-residents (2026)

How is a Delaware LLC taxed at the federal level?

A single-member US LLC owned by a non-resident is treated as a disregarded entity for federal tax purposes by default (Treas. Reg. § 301.7701-2). "Disregarded" means the IRS ignores the LLC for income-tax purposes and looks through to the owner. A multi-member LLC defaults to partnership treatment and files Form 1065 with K-1s to each member. Either default classification can be changed by filing IRS Form 8832 ("check-the-box") to elect C-Corp taxation.

For a non-resident owner of a single-member disregarded LLC, US tax is owed on income that is:

• Effectively connected with a US trade or business (ECI). Income from services performed in the US, sales of US inventory, or operating a US business. Taxed at graduated rates on Form 1040-NR.
• Fixed, determinable, annual, or periodical income (FDAP). Generally US-source passive income (dividends, certain royalties, certain rents). Taxed at flat 30% (or lower treaty rate) usually via withholding at source.

Pure online services delivered to US customers from abroad may or may not be ECI; the analysis is fact- specific and depends on whether you have a US trade or business and whether the income is effectively connected with that trade or business. A CPA familiar with the ECI analysis is essential before assuming income is or is not US-taxable. Many non-resident e-commerce and freelance founders running through a Delaware LLC have no ECI and therefore no US federal income tax obligation beyond the Form 5472 information return.

The pass-through mechanic explained

Pass-through means the LLC itself does not pay income tax at the entity level. Instead, profits and losses "pass through" to the owner's personal tax return. For a single-member disregarded LLC, this is mechanically simple: the LLC's income is reported on the owner's Form 1040-NR (for non-residents) or Form 1040 Schedule C (for US persons).

For a multi-member LLC defaulting to partnership treatment, the mechanic is more complex: the LLC files Form 1065 partnership return, allocates income and deductions to each member via Schedule K-1, and each member reports their allocated share on their own return. Form 8804 and Form 8805 may apply for foreign-partner withholding.

The pass-through default is one of the main reasons non-resident bootstrap founders prefer LLCs over C-Corps. C-Corps pay 21% federal corporate tax on profits and then dividends are taxed again at the shareholder level (often 30% withholding for non-residents, possibly reduced by tax treaty). The combined federal tax burden on a C-Corp with foreign owners is meaningfully higher than the pass-through LLC.

Does the LLC owe Delaware state income tax?

Delaware does not impose state income tax on LLCs whose income is earned outside Delaware (6 Del. C. Title 30 § 1126). Most non-resident-owned Delaware LLCs have no physical presence in Delaware, no Delaware employees, and no Delaware-source income. They owe only the $300 annual franchise tax (a flat fee, not an income tax) under 6 Del. C. § 18-1107(b).

Delaware also does not have a state-level sales tax. There is a gross receipts tax that applies to businesses with Delaware nexus, but it generally does not reach non-resident-only e-commerce or SaaS LLCs with no Delaware operations. Delaware Corporations doing business in Delaware are subject to the Delaware corporate income tax at 8.7% on in-state net income, but this applies only to Delaware-source income.

Practically: a typical non-resident-owned Delaware LLC running an e-commerce, freelance, or SaaS business from abroad owes $300 per year to Delaware as the franchise tax, and nothing else to Delaware state. The Delaware portion of the annual tax bill is therefore predictable and small.

Other US states: when does foreign qualification kick in?

A Delaware LLC operating in other US states may need to register as a foreign LLC in those states. The trigger is "nexus": a meaningful business connection that causes a state to assert tax or registration jurisdiction. Nexus can come from:

• Physical presence (an office, warehouse, or employee in the state).
• Economic nexus (sales above state-specific thresholds, common for sales-tax purposes post-Wayfair).
• Affiliate nexus (relationships with in-state affiliates that generate sales).

Most non-resident-only Delaware LLCs have no nexus in any US state (they have no US physical presence at all). They do not need to register as foreign LLCs anywhere except Delaware. The exceptions:

• If you eventually hire a US-based employee, the state where the employee works will likely assert nexus.
• If you rent a US office, warehouse, or storage location (including Fulfillment by Amazon warehouse locations in some interpretations), the host state may assert nexus.
• If your sales-tax-economic-nexus thresholds are crossed in a state, you may owe state sales tax even without physical presence.

California specifically charges an $800 minimum LLC tax per year regardless of revenue, on any LLC that does business in California. New York requires biennial statements and may impose foreign-qualification fees. Texas has its own franchise tax. The economic-nexus rules change frequently and are state-specific.

Form 5472: the federal information return non-residents owe

Foreign-owned single-member US LLCs treated as disregarded entities must file IRS Form 5472 along with a pro forma Form 1120 each year, regardless of whether there were any reportable transactions. The penalty for missing this is $25,000 per occurrence (IRS Instructions for Form 5472). Form 5472 is the single largest tax-compliance risk in the structure. See the dedicated Form 5472 guide for the full breakdown.

Note that Form 5472 is an information return, not an income-tax return. The form reports related-party transactions between the LLC and its 25% foreign owner. Even a zero-transaction year still requires Form 5472 filing as long as the LLC exists. The pro forma Form 1120 is a placeholder that exists to provide a filing vehicle for the Form 5472.

ITIN: when do you need one and when can you skip it?

The ITIN (Individual Taxpayer Identification Number) is the owner's personal US tax ID for filing personal tax returns. Most non-resident LLC owners need the EIN (the LLC's tax ID) but never need an ITIN.

You need an ITIN only if you personally must file a US tax return (Form 1040-NR) showing US-source effectively- connected income. For most non-resident-owned Delaware LLCs with no US physical presence and no US-employee operations, the federal filing obligation is Form 5472 + pro forma Form 1120 (handled by a CPA), and you personally do not file a Form 1040-NR. If that is your situation, you do not need an ITIN.

If you do eventually need an ITIN, the application is via IRS Form W-7 with required identification documentation. A Certifying Acceptance Agent (CAA) can certify your passport rather than mailing the original to the IRS. The ITIN application takes 6-12 weeks. CAAs charge $100-$300 for the certification service.

Tax treaties: how they may apply

The United States has bilateral income tax treaties with approximately 70 countries. Treaty provisions can reduce withholding tax on US-source income for treaty residents and can provide rules for which country has primary taxing jurisdiction over specific income types.

Pass-through LLC income is not always treaty-eligible at the LLC level. The analysis depends on:

• Whether the income is treated as the foreign owner's distributive share of income from a US trade or business.
• Whether the LLC's activities create a permanent establishment in the US under the relevant treaty's PE article.
• Whether the treaty's limitation-of-benefits article restricts treaty access for the specific income type.
• Whether the home-country tax authority recognizes the LLC as fiscally transparent or as a corporate entity for treaty purposes.

Countries with US tax treaties relevant to Delewarellc's customer base: India, Pakistan, Bangladesh, Indonesia, the Philippines, Egypt, and most European countries. UAE has a limited treaty primarily covering shipping and air- transport income. Nigeria does not currently have a ratified income tax treaty with the United States. The full list is published at irs.gov.

Talk to a CPA in your home country before relying on specific treaty rates. Different home countries treat US pass-through LLC income very differently (some treat the LLC as fiscally transparent like the US does, others treat it as a foreign corporation), and the coordination matters.

Home-country taxation: the other half of the analysis

Home-country taxation matters as much as US taxation. Most countries tax residents on worldwide income, including distributions and capital gains from foreign- owned LLCs. Pass-through LLC income may be treated as the owner's personal income in the home country. Some countries tax the LLC's profits as they accrue; others tax only on distribution.

Patterns across Delewarellc's customer base:

• India: Indian residents are taxed on worldwide income. The Income Tax Act treats US LLC income on a fact-specific basis; foreign-source pass-through income flows into the Indian return. The DTAA with the US allows treaty-credit for US tax paid.
• Pakistan: Pakistani residents are taxed on worldwide income. The FBR's treatment of US LLC pass-through income is fact-specific; coordinate with a Pakistani CA who handles US-client billing.
• Bangladesh: Bangladeshi residents are taxed on worldwide income. The NBR treats US LLC pass-through income on a fact-specific basis.
• Nigeria: Nigerian residents are taxed on worldwide income. Absence of a US-Nigeria tax treaty means treaty-credit rules do not provide relief; FIRS treatment is fact-specific.
• UAE: UAE residents have generally no personal income tax obligation at home. The UAE Corporate Tax (effective June 2023) imposes 9% on UAE-entity income above AED 375,000; whether it reaches US LLC pass-through income flowing to a UAE individual is fact-specific.

The US side of the analysis is one half. The home-country side is the other half, and the two need to be coordinated for the LLC structure to make sense over multiple years. A US-based CPA alone is not sufficient; you also need a home-country tax adviser who understands cross-border structures.

BOI report: the FinCEN obligation separate from tax

Beneficial Ownership Information (BOI) reports under the Corporate Transparency Act became enforceable in stages from 2024. Newly formed entities currently must file with FinCEN within 90 days of formation. The penalty for non-filing is $591 per day, plus criminal exposure up to $10,000 and 2 years prison for willful violations.

BOI is not a tax filing. It is a beneficial-ownership transparency filing separate from federal tax. FinCEN, not the IRS, administers BOI. The filing is free at fincen.gov/boi, takes 15-20 minutes online, and is a one-time filing per ownership-change event (not annual). Delewarellc sends a reminder before the 90-day window closes.

What does it cost to comply with all of this?

Annual compliance cost for a typical non-resident-owned single-member Delaware LLC:

• $300 Delaware annual franchise tax (paid to the state, free of charge to file).
• $0 BOI report (free, one-time at formation; FinCEN does not charge).
• $200-$500 CPA fee for Form 5472 + pro forma Form 1120 each year.
• $0 Form 1040-NR if you have no US-source ECI (most non-resident-only LLCs).
• $0 home-country LLC-related filings if your home country has no separate filing for US LLC income (some countries require disclosure of foreign holdings).
• Optional: $200-$500 CPA consultation for tax-planning around treaty positions.

Total annual compliance: approximately $500-$1,000 per year for an uncomplicated structure, or $1,500-$3,000 per year for a structure with significant cross-border complexity.
