Delaware LLC Profit & US Tax (2026)

How does the US tax a non-resident’s Delaware LLC profit?

The single most common misunderstanding among non-resident founders is that a US Delaware LLC automatically owes US income tax on all of its profit. It does not. The United States taxes a non-resident on only two categories of income: income effectively connected with a US trade or business, known as ECI, and certain US-source fixed, determinable, annual or periodical income, known as FDAP. Everything outside those two buckets is, for a non-resident, generally outside the US income tax net.

A single-member Delaware LLCis by default a disregarded entity, so it pays no entity-level federal income tax. Its income is treated as belonging to the owner. For a non-resident owner, the question then becomes whether that income is ECI, US-source FDAP, or foreign-source — and that classification, not the LLC’s registration state, is what decides the US tax. The deeper picture for internationally owned companies sits in our Delaware LLC for non-residents guide.

This page is an informational guide with worked examples. It is not a live calculator and not a substitute for advice from a cross-border CPA who has seen your contracts, where your work is performed, and any treaty between the US and your country. Use it to understand the framework, then confirm your own numbers with a professional.

Throughout this guide we deliberately refrain from quoting a single headline percentage for “the tax on Delaware LLC profit.” There is no such number, and any source that offers one is glossing over the part that actually decides your bill: how each stream of income is sourced and classified. Two non-residents with identical profit can face completely different outcomes — one with zero US income tax, the other with a 30% withholding charge — purely because of where the work happened and what kind of income it was. The framework below is what lets you tell which situation is yours.

What is the difference between ECI and FDAP?

ECI and FDAP are taxed very differently, and knowing which one applies is the whole game. ECI — effectively connected income — is income tied to actually carrying on a trade or business inside the United States. It is taxed on a net basis at the same graduated rates a US person pays, meaning you deduct business expenses first and pay tax on the profit. Filing ECI is done on a US non-resident return.

FDAP is passive US-source income such as certain interest, dividends, rents, and royalties. It is taxed on a gross basis at a flat 30%, with no deductions, unless a tax treaty in force reduces the rate. The contrast matters: $10,000 of US-source royalty FDAP with no treaty is a flat $3,000 of tax on the gross, while $10,000 of ECI is taxed net at graduated rates after your expenses. Most non-resident service and product businesses run through a Delaware LLC generate neither US-source FDAP nor a US trade or business at all — which is why so many owe no US income tax despite a profitable year.

Why are services performed abroad generally not US-taxed?

US tax law generally sources personal-services income to where the work is physically performed. If you and your team are sitting outside the United States when you write the code, design the brand, run the consulting call, or fulfil the order, that income is typically foreign-source. Foreign-source income earned by a non-resident is generally outside the US income tax net — even when a US-registered Delaware LLC sends the invoice and the payment lands in a US bank account.

This is the point that surprises people most. The LLC being American does not make its profit American-source, and it does not, on its own, create a US trade or business. A freelancer in Lahore, a SaaS team in Dhaka, or a consultant in São Paulo can run revenue through a Delaware LLC and a US Stripe account while the underlying services remain foreign-source. What can change the answer is a genuine US presence — for example, employees or dependent agents working inside the US on your behalf, or a fixed place of business there. Because that line is fact-specific, it is exactly the kind of thing to confirm with a CPA rather than assume.

It also helps to be precise about what “US-source” means, because the customer’s location and the source of the income are not the same thing. Selling to American customers does not, by itself, make your income US-source. A consultant in Manila who advises a New York client while sitting in Manila has performed the service abroad; the customer’s location does not relocate the work. The same logic holds for software written abroad, designs delivered abroad, or goods handled by a third-party fulfilment provider. What shifts the analysis is your own physical or agency presence inside the United States, not the address of the people who pay you.

Worked example: a non-resident freelancer with no US activity

Consider a designer based outside the United States who forms a Delaware LLC and bills clients through it. She has no US office, no US employees, and performs every project from her home country. Suppose the LLC earns revenue and, after expenses, shows a profit for the year. Where is that income sourced, and what does the US tax?

Because the services are performed entirely abroad, the income is generally foreign-source. There is no US trade or business, so there is no ECI. There is no US-source interest, dividend, rent, or royalty, so there is no FDAP. The likely result: no US income tax on the profit. What she still owes is the federal information filing — Form 5472 with a pro forma Form 1120 — plus, from year two, Delaware’s flat $300franchise tax. Note we are not putting a tax figure on her profit, because no fixed rate applies to foreign-source income of a non-resident; the honest answer is “generally zero US income tax, confirm with a CPA.”

Worked example: US-source royalty income (FDAP)

Now change the facts. The same owner licenses intellectual property to a US company, and the licence produces a US-source royalty. Royalties of this kind are classic FDAP. If there is no tax treaty in force between the US and the owner’s country, the statutory rate is a flat 30% on the gross royalty, typically withheld at source by the payer. There are no deductions against FDAP, so the tax is calculated on the full payment, not on a net margin.

If a treaty is in force and covers royalties, it may reduce that 30% to a lower figure or to zero for the covered category. The reduced rate is not automatic — it must be claimed, usually on a withholding form given to the payer or on a US return. The practical takeaway: the same owner can have foreign-source service income that is not US-taxed andUS-source FDAP that is, in the same year, through the same LLC. Sourcing each stream correctly is what a cross-border CPA does, and why a single blended “tax rate” on total profit would be misleading.

One more nuance is worth flagging on this example. The 30% on FDAP is a gross charge, which means it can feel heavy relative to the underlying margin: if the licence costs little to maintain, 30% of the gross royalty is close to 30% of the economic profit, with no deductions to soften it. That is the opposite of how ECI works, where expenses come off first. It is also why a treaty in force can matter so much for royalty-heavy businesses — moving a covered royalty from 30% to a single-digit treaty rate, or to zero, is often the difference between a workable structure and an uncompetitive one. None of this is automatic; the treaty position has to be claimed and documented, and that is squarely CPA territory.

What must every foreign-owned Delaware LLC file regardless of tax?

Whether or not any US income tax is due, a foreign-owned single-member Delaware LLC treated as a disregarded entity has a hard federal obligation: file Form 5472 attached to a pro forma Form 1120 every year. This is an information return, not a tax bill. It reports reportable transactions between you and your LLC — money you put in to fund it, amounts you take out, loans, and similar dealings between owner and company.

The penalty for failing to file is $25,000 under IRC 6038A, and it applies even if the LLC made no money and owed no tax. Treat the filing as mandatory from year one. The full mechanics, including the reportable-transaction categories and the pro forma 1120 layout, are in our Form 5472 for Delaware LLCs guide, and the broader US picture is covered in our Delaware LLC taxes overview.

When is Form 5472 due and how is it filed?

For a calendar-year LLC, the package is due April 15. You can get an automatic extension to October 15 by filing Form 7004on or before April 15. The pro forma 1120 carries only the LLC’s name, address, and EIN at the top of the form; the substance lives on the attached Form 5472. Because a foreign-owned disregarded entity files this package by mail or fax rather than the normal e-file route, give yourself extra lead time so it arrives on time.

You need an EIN before you can file, and for applicants without a US Social Security Number the IRS issues the EIN in roughly 2 to 4 weeks. Our EIN for a Delaware LLC guide walks through the no-SSN path. If you are still at the formation stage, our how it works page lays out the full sequence from filing to EIN to banking.

How does the Delaware franchise tax fit into this?

Delaware’s LLC franchise tax is a flat $300 per year and is completely unrelated to your profit. It does not scale with revenue, members, or assets, and there is no annual report for an LLC. It is due June 1each year starting from the LLC’s second calendar year. The first year is free of the franchise tax.

The reason this belongs in a profit-and-tax guide at all is that founders routinely conflate the $300 franchise tax with income tax, and then either over- or under-estimate what they owe. They are unrelated. The $300 is a fixed cost of keeping a Delaware LLC in good standing, owed even in a loss-making year; the income-tax analysis above is a separate question driven by sourcing, ECI, and FDAP. Keeping the two in different mental buckets prevents the common error of assuming a profitable LLC owes the franchise tax plus a percentage of profit to Delaware. Delaware imposes no state income tax on an LLC with no Delaware-based operations, so for most non-resident owners the entire Delaware-level cost is that one flat $300 line.

A frequent mix-up is worth clearing up directly: the authorized-shares and assumed-par-value calculation methods — the ones that rise with company size — apply to Delaware corporations, not to LLCs. An LLC simply pays the flat $300. Miss the June 1 deadline and Delaware adds a $200 penalty plus 1.5% interest per month and the LLC loses good standing. The full breakdown, including the corporation methods, is on our Delaware franchise tax page.

What about 1099-K reporting from Stripe or marketplaces?

If you collect payments through a US processor such as Stripe or a US marketplace, you may receive a 1099-K. The reporting threshold is payments exceeding $20,000 AND more than 200 transactions in a year. The much-discussed $600 threshold was repealed by the One Big Beautiful Bill Act (OBBBA), so the $20,000-and-200 test is the one that applies.

A 1099-K reports gross payment volume. It is not a tax bill, and it does not decide whether your income is US-taxable — that still turns on sourcing, ECI, and FDAP as described above. The practical job is to keep clean books so any 1099-K figure reconciles to your own records. Note too that opening a Stripe account or a US bank account is the provider’s decision and is never guaranteed; our Delaware LLC banking guide covers how to present a clean application.

Are BOI / FinCEN beneficial-ownership rules a tax filing?

No — beneficial-ownership reporting is separate from tax, and it changed in 2025. A March 2025 FinCEN interim final rule removed BOI reporting for US domestic reporting companies. Under that rule, only certain foreign reporting companies registered to do business in the US remain in scope, and US-formed entities are generally exempt from providing beneficial-ownership information.

This area is still evolving, so do not treat any summary as final. Confirm the current FinCEN position at the source before relying on your filing status. It is worth keeping BOI mentally separate from the tax and franchise items above: they are different regimes, with different agencies, deadlines, and consequences.

How should a non-resident actually estimate the tax?

Put the pieces together in order rather than reaching for a single percentage. First, work out the LLC’s profit (revenue minus expenses). Second, split that income by source — what was earned from services performed abroad (generally foreign-source) versus anything US-source. Third, test the US-source slice: is it ECI (taxed net at graduated rates) or FDAP (30% flat, treaty-reduced only if a treaty is in force)? Fourth, apply any treaty actually in force with your country.

For a large share of non-resident founders running offshore service or software businesses, the honest estimate is no US income tax on the profit, plus the flat $300 Delaware franchise tax from year two and the mandatory Form 5472 filing. We deliberately avoid printing a tax figure on your profit here, because no fixed rate applies to foreign-source income and the US-source analysis depends entirely on your facts.
