U.S. Tax for Nigerian and African Founders Using U.S. Entities

A growing number of founders across Nigeria and other African markets form U.S. entities, most commonly a Delaware C-corporation or a Wyoming LLC, to access U.S. payment infrastructure, sell software and services into global markets, and, in some cases, raise U.S. venture capital. The underlying U.S. tax questions are largely the same ones any foreign founder faces. One structural fact recurs across the region and deserves to be named directly: most African countries do not have a comprehensive U.S. income tax treaty in force, and Nigeria is among them.

Check treaty status by country, not by continent

This is the first question to answer for any specific founder, and it should be checked country by country rather than assumed for the region as a whole. A small number of African countries, including Egypt and South Africa, have a U.S. income tax treaty in force, each negotiated on its own terms and worth reviewing individually rather than assumed to mirror one another. Nigeria does not have one, and neither do most other African countries a U.S.-facing founder is likely to be resident in.

Where no treaty exists, the same two consequences apply that apply to any non-treaty country. There is no treaty tie-breaker available to resolve U.S. tax residency if the substantial presence test under IRC §7701(b)(3) is met; the only fallback is the closer connection exception filed on Form 8840, which requires presence of fewer than 183 days in the current year, a tax home maintained abroad for the year, and a demonstrable closer connection to the home country. And U.S.-source FDAP payments, dividends, interest, most royalties, are withheld at the full statutory 30% rate under IRC §871(a) and §881, collected at source under §1441 and §1442, with no treaty article available to bring the rate down. This should be confirmed for the specific country a founder is resident in rather than assumed either way, since treaty status is genuinely inconsistent across the continent and it changes the withholding answer materially.

Why U.S. entity formation is so common from this region specifically

A U.S. LLC or C-corporation provides access to U.S. banking relationships and U.S. payment processing infrastructure, Stripe and comparable processors, correspondent banking, and straightforward invoicing in U.S. dollars, that is materially harder to obtain directly through many home-market banking systems. That access, rather than any actual shift in where the underlying business operates, is frequently the primary reason the U.S. entity exists at all.

The tax consequence of this pattern is that a large number of these are businesses with real staff, real operations, and real customers located entirely outside the United States, using a U.S. entity purely as financial infrastructure. That is a legitimate and increasingly common structure. It does not, by itself, create U.S.-taxable business income for the founder, since the underlying "engaged in a U.S. trade or business" analysis under domestic law generally turns on whether there is regular, continuous, considerable activity actually occurring in the United States, not on where the entity happens to be incorporated. But the entity itself still owes its own U.S. information filings because of its foreign ownership, entirely independent of where the operating business is actually located or whether it has any U.S.-source income at all.

EIN and banking access without an SSN

A founder without a U.S. Social Security Number can still obtain an Employer Identification Number for the U.S. entity. Form SS-4 asks for a responsible party and that person's taxpayer identification number; where the responsible party has no SSN or ITIN, current IRS practice is to enter "FOREIGN" in that field rather than leave it blank. The IRS's online EIN application requires the responsible party to already hold an SSN or ITIN and is closed to most foreign founders for that reason, but the paper-based routes, fax, mail, or the IRS's dedicated international telephone line, remain fully available and do not require an ITIN to obtain an EIN. This is a common point of confusion: an EIN for the entity and an ITIN for the individual founder are separate numbers serving separate purposes, obtained through separate applications, and a founder does not need the ITIN first to get the EIN.

Banking is a separate and often harder step than the EIN itself. Opening a U.S. business bank account generally requires identity verification under the Customer Identification Program rule at 31 CFR §1020.220, and many traditional U.S. banks expect an in-person visit or, at minimum, extensive documentation that can be difficult to assemble remotely. A number of fintech platforms built specifically for foreign-owned U.S. entities have made remote account opening more accessible in recent years, though the underlying identity verification requirement does not disappear; it is simply satisfied through a different process. A founder should expect banking access, not the EIN application, to be the longer and more variable step in getting a U.S. entity operational.

The most expensive and most common mistake

Treating the U.S. entity as though it were purely a payment-processing convenience with no compliance obligation attached is the single most consequential and most common error in this pattern. A U.S. entity that is more than 25% foreign-owned, or a wholly foreign-owned single-member LLC that is disregarded for U.S. tax purposes, is required to file an annual Form 5472 attached to a pro forma Form 1120 under IRC §6038A, reporting transactions with its foreign owner, regardless of whether the entity has any income connected to U.S. business activity at all. Capital contributions, loans between the owner and the entity, and payments the owner makes on the entity's behalf all count as reportable transactions.

IRC §6038A(d)(1) sets the penalty for a missing or late Form 5472 at $25,000, with an additional $25,000 for each 30-day period of continued failure after IRS notice under §6038A(d)(2). The pattern that produces this penalty most often is exactly the one described above: an entity formed quickly through an online formation service, funded and used entirely as banking and payment infrastructure for a business operating elsewhere, with no U.S. federal filing ever made against it because no one along the way flagged that a filing was required in the first place.

A worked comparison across three founders

Consider three founders, each the sole owner of an identical Delaware C-corporation earning $150,000 of net profit and distributing $80,000 as a dividend, resident respectively in South Africa, Egypt, and Nigeria.

Item	South Africa	Egypt	Nigeria
Treaty in force	Yes	Yes	No
Entity-level U.S. corporate tax and Form 5472	Applies regardless	Applies regardless	Applies regardless
Dividend withholding rate	Reduced under the applicable treaty	Reduced under the applicable treaty	Full 30% under IRC §871(a)/§1441
Withholding on the $80,000 dividend	Below $24,000	Below $24,000	$24,000
Treaty residency tie-breaker available	Yes	Yes	No; closer connection exception only

The entity-level obligations, corporate tax and the Form 5472 filing, are identical across all three founders. Everything that differs sits at the point profits actually leave the U.S. entity and reach the individual, which is exactly where a treaty does its work and exactly where its absence is felt.

Why entity structuring choices matter more here, not less

Because a Nigerian or other non-treaty African founder cannot rely on a treaty to reduce distribution withholding or provide a residency backstop, the choice between a pass-through LLC and a C-corporation carries more weight than it would for a founder from a treaty jurisdiction. A disregarded single-member LLC generally passes income through to the founder directly, taxed under the ordinary FDAP or effectively-connected-income framework with no separate corporate-level tax and no dividend withholding step layered on top. A C-corporation, which is often required for founders planning to raise U.S. venture capital, introduces the two-layer result shown above: corporate tax, then full 30% withholding on whatever is actually distributed to a non-treaty owner.

This does not mean a non-treaty founder should default to an LLC. It means the trade-off between the two structures should be evaluated with the withholding consequence explicitly in view, rather than defaulting to whichever structure a formation service's template happens to set up, since the cost of an unfavorable choice is not offset by treaty relief the way it might be for a founder from a treaty country.

When does the founder personally need an ITIN?

An Individual Taxpayer Identification Number, obtained through Form W-7, is a separate matter from the entity's EIN and is needed only where the individual founder has a U.S. filing obligation of their own, most commonly because the founder is filing Form 1040-NR to report U.S.-source income not otherwise fully satisfied by withholding, or because the founder is claiming a benefit that specifically requires a U.S. taxpayer identification number. A founder who receives dividends from the U.S. entity, taxed as FDAP income withheld at 30% under the default rule described above, does not necessarily need an ITIN simply to receive that dividend; the withholding agent generally applies the flat rate based on the Form W-8BEN on file and remits the tax without the recipient needing to file a return at all, since the withholding is treated as final for straightforward FDAP income. An ITIN becomes necessary where the founder needs to file a return, for example to claim a refund of over-withheld amounts, to report income effectively connected with a U.S. trade or business, or to satisfy a specific documentary requirement tied to another filing. Confirming which of these situations actually applies before starting the Form W-7 process avoids an unnecessary application, since the ITIN process itself, which generally requires original or certified copies of identity documents submitted alongside the return that creates the need for the number, takes real time to complete correctly.

Services performed from home, sourced outside the United States

A Nigerian founder who performs services personally, consulting, software development, or design work billed through the U.S. entity, while physically located in Nigeria, is generally earning foreign-source income under the sourcing rules that look to where services are actually performed rather than to the location of the payer or the entity issuing the invoice. Foreign-source personal services income is generally outside the scope of U.S. withholding altogether, independent of the treaty question entirely, because the income was never U.S.-source to begin with. This distinction matters in practice because it is easy to conflate "paid by a U.S. entity" with "U.S.-source income," and the two are not the same thing. A founder who travels to the United States and performs some of that same work while physically present there converts that portion of the income to U.S.-source, which is one more reason to track U.S. travel days carefully, both for the substantial presence test discussed above and for sourcing purposes on income earned during any U.S. trip specifically.

What to check

Confirm whether your specific country of residence, not the continent generally, has a U.S. income tax treaty in force, since that single fact determines the withholding rate on any U.S.-source payments and whether a residency tie-breaker is available. Confirm the U.S. entity has actually filed its Form 5472 for every year it has existed, including years it was used purely as payment infrastructure with no operating income, since that filing requirement is not optional and the $25,000 minimum penalty applies whether or not the entity ever earned a dollar of U.S. business income. And weigh the LLC-versus-C-corporation decision with the absence of treaty-reduced distribution withholding explicitly in mind, since that is one of the few levers actually available to a non-treaty founder where a treaty-country founder would have another one.
