US LLC for a Ukrainian IT company: what it really costs and reports

The short answer

A US company solves market problems. Tax is not one of them. It gives you a US contracting face, access to Stripe and US card rails, and the Delaware C-Corp that US investors expect. For a Ukrainian tax resident it changes nothing positive about your tax bill, and it adds a second compliance system on top of the Ukrainian one you already run.

The questions owners actually ask, answered first:

• Will I pay tax twice, in the US and Ukraine? For a single-member LLC delivering services from Ukraine, no. The LLC owes $0 US federal income tax, because services are sourced where the work is done. You pay only the Ukrainian layer. For a C-Corp, yes: 21% US corporate tax, then dividend withholding, then the Ukrainian owner layer on top.
• Does owning a US company make me a US taxpayer, or require a visa? No. Owning a US LLC does not make you a US tax resident and grants no immigration status. A non-resident with no US income files no US personal return.
• Can I really get Stripe and a US bank from Ukraine? Stripe, usually yes for a registered US entity. A US bank account is the hard part: the two neobanks every formation agency recommends, Mercury and Relay, both prohibit founders resident in Ukraine.
• What does it really cost? Very little to form, more to keep clean. The mandatory recurring floor is the state fee, a registered agent, the annual Form 5472 preparation, and your Ukrainian CFC report.
• LLC or C-Corp? LLC for a service agency, solo SaaS, or a US face. C-Corp only for a US venture round.
• Should I just keep my ФОП? For pure tax, yes. A third-group ФОП at roughly 6% all-in beats every US structure. Add a US company on top only for what the ФОП cannot do: present a US face, run Stripe, or hold an investor’s equity.

This is the deep dive behind the US summary in Open a company abroad, the structural twin of the Estonia OÜ guide, and it reuses the framework from CFC reporting for Ukrainian IT owners. Those carry the CFC mechanics, the abroad comparison, and the Estonian detail left aside here.

When a US entity helps, and when it does not

A US entity earns its keep when the problem is commercial and US-facing. A US client’s procurement wants to contract with and pay a US entity. A product company needs Stripe or US card acquiring. You are raising from US VCs, who expect a Delaware C-Corp. Or the business genuinely has US-side operations and a US market presence.

It is unnecessary, or actively counterproductive, in three common cases. When the only goal is to pay less tax, a US entity changes nothing positive for a Ukrainian-resident owner and adds a second compliance system. When your buyers are EU clients already happy to sign a Ukrainian ТОВ or an Estonian company, a US entity adds nothing to the contract. And when you want a foreign bank account, the US is the hardest of the common jurisdictions to bank from Ukraine, not the easiest.

Compare the Ukrainian baseline first. For getting cash into a Ukrainian founder’s pocket at a low rate, a ФОП, a ТОВ, or Diia.City usually beats a US wrapper, and the Ukrainian options keep the talent-retention and reservation benefits a US entity cannot give. Decide what specific US-facing job the entity does before you form it.

LLC or C-Corp, and in which state

“LLC versus Delaware C-Corp” is really two decisions wearing one name. One axis is US tax classification. The other is the state of formation. Keep them apart.

On tax classification, the IRS default does most of the work:

“For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and affirmatively elects to be treated as a corporation.”

A single-member LLC is “disregarded,” which means it is a pass-through with no separate US tax return of its own. Add a second member, even a co-founder or a spouse, and the default changes:

“Pursuant to the entity classification rules, a domestic entity that has more than one member will default to a partnership.”

That flip matters. A multi-member LLC files Form 1065, issues Schedule K-1s, and if it has US effectively connected income it faces foreign-partner withholding under section 1446 at 37% for non-corporate partners and 21% for corporate partners. The tax can still be zero when all work is performed in Ukraine, but the filing load is real. Keep the LLC single-member unless you have a strong reason not to.

A C-Corp is a different animal. It is a separate US taxpayer from day one:

“Corporations, including qualified personal service corporations, figure their tax by multiplying taxable income by 21% (0.21).”

The 21% attaches to the corporation regardless of where the owner lives. Distributed profit is then taxed again as a dividend. That double layer is the structural reason a service agency that just wants a US contracting face should not default to a C-Corp.

The C-Corp exists for one job: it is the vehicle US venture investors require, because only C-Corp stock can qualify as QSBS under section 1202. The 2025 reconciliation act made QSBS more generous, but the benefit accrues to US-taxable shareholders, not to a nonresident Ukrainian founder whose share-sale gain is generally not US-taxed anyway. Do not let a §1202 pitch sell a Ukrainian owner a structure built for someone else’s tax.

	Single-member LLC	Delaware C-Corp
US entity tax	None (disregarded, pass-through)	21% federal
Owner US tax on Ukraine-performed services	$0 (foreign-source)	Corp is the taxpayer
Dividend to owner	n/a	30% default, 5% or 15% by treaty
Required US filing	Form 5472 + pro-forma 1120	Full Form 1120
Fits	Service agency, solo SaaS, US face	US venture round
Against the Ukrainian 13% CFC gate	Fails (0% US tax)	Can pass (21% on US-taxed income)

The state is a separate, cheaper-or-dearer choice. Delaware is the default, but it is not the cheapest. A Delaware LLC pays a flat $300 a year. Wyoming runs an annual license tax with a $60 minimum and levies no state income tax. New Mexico vendors advertise no annual report and a one-time $50 filing fee, though that “no report” point rests on vendor pages rather than a prominent state statement.

For a solo founder not raising venture money, Wyoming or New Mexico is cheaper to maintain. Delaware’s real value is corporate-law familiarity and VC expectation, which only matters for the C-Corp case. Separate “which form” from “which state,” and do not pay for Delaware unless the venture path needs it.

What a foreign-owned US entity has to file

Two filings scare owners, for good reason.

Form 5472, and the $25,000 trap

A foreign-owned US disregarded entity is a reporting corporation for this purpose:

“A reporting corporation is either: A 25% foreign-owned U.S. corporation (including a foreign-owned U.S. disregarded entity (DE)), or A foreign corporation engaged in a trade or business within the United States.”

It owes no income tax, but it must still file:

“While a foreign-owned U.S. DE has no income tax return filing requirement… it will now be required to file a pro forma Form 1120, U.S. Corporation Income Tax Return, with Form 5472 attached by the due date (including extensions) of that Form 1120.”

The reportable transactions that trigger the filing include the act of forming and funding the entity:

“These transactions include amounts paid or received in connection with the formation, dissolution, acquisition, and disposition of the entity, including contributions to, and distributions from, the entity.”

In practice that means year-one funding alone makes the 5472 due, so treat it as an annual filing. The penalty is flat and uncapped:

“A penalty of $25,000 will be assessed on any reporting corporation that fails to file Form 5472 when due and in the manner prescribed.”

“There is no maximum penalty amount.”

This is a $25,000 information-return penalty, not a percentage of tax. It bites precisely the owner who reasons “no US tax, so nothing to file.” The form cannot be e-filed by a disregarded entity:

“If you are a foreign-owned U.S. DE, you cannot file Form 5472 electronically.”

You fax or mail it. For a calendar-year filer the deadline is the 15th day of the 4th month after year-end, so April 15, 2026 for the 2025 year, extendable to roughly October 15 with Form 7004.

A C-Corp does not escape this form. A 25% foreign-owned US corporation is itself a reporting corporation, so a Delaware C-Corp owned by a Ukrainian founder still files Form 5472 for related-party transactions such as founder loans, reimbursements, or intercompany services, on top of its full Form 1120.

The EIN, the only real bottleneck

A foreign owner with no US Social Security Number can still get an Employer Identification Number. On Form SS-4:

“Enter ‘foreign’ or N/A on line 7b if the responsible party doesn’t have and is ineligible to obtain an SSN or ITIN.”

International applicants apply by phone, because the online portal is closed to them:

“If your principal place of business is outside the U.S., you can apply for an EIN by phone at 267-941-1099.”

The EIN is the slow step in forming the entity. It blocks nothing in the end, but it sets the timeline. By phone it can land on the same call; by fax, usually a few business days; by mail, the IRS asks for four to five weeks.

Does the LLC owe US income tax? Usually not

The load-bearing fact is the source rule. Services income is sourced where the work happens:

“The place, where the personal services are performed, generally determines the source of the personal service income, regardless of where the contract was made, or the place of payment, or the residence of the payer.”

And foreign-source income of a non-resident is outside the US net:

“Foreign source income received by a nonresident alien is not subject to United States (U.S.) taxation unless such income is ECI.”

A Ukrainian founder coding in Kyiv for US clients earns foreign-source income, so the LLC’s service fees attract $0 US federal income tax. Three caveats. Working physically on US soil makes that slice US-source. US-source passive income (US dividends, interest, royalties, rents) is taxed at a flat 30% gross under the FDAP rules unless a treaty cuts it. And none of this removes the Form 5472 duty.

The personal fear is worth killing directly. US tax residency for a non-citizen runs on the green-card test or the substantial-presence test, not on owning a company. Holding a US LLC does not make you a US tax resident, does not require a visa, and does not create a US personal filing duty. A non-resident with no US-source income and no US trade or business files no Form 1040-NR. The only US filing the structure forces is the LLC’s own Form 5472 and pro-forma 1120.

Delaware franchise tax, and the sticker shock

For a Delaware LLC the bill is simple:

“All Domestic and Foreign Limited Liability Companies… are required to pay an annual tax of $300.00. There is no requirement to file an Annual Report… due on or before June 1st.”

For a Delaware corporation the date and the mechanics differ:

“All active Domestic Corporation Annual Reports and Franchise Taxes for the prior year are due annually on or before March 1st.”

The trap is the default calculation. Delaware first computes a corporation’s franchise tax on the Authorized Shares Method, which scales with share count: 5,000 shares or less pays the $175 minimum, and the State’s calculator notes that “A corporation with 100,000 shares authorized pays $1,015.00.” A startup that authorizes ten million shares sees a default bill in the tens of thousands. The fix is to recompute under the Assumed Par Value Capital Method, keyed to actual gross assets, where the minimum is $400 and the State’s own rule says to use whichever method gives the lesser tax. An early-stage C-Corp that does this pays near the $400 minimum. Do not pay the scary default number.

Note the date asymmetry: a Delaware LLC pays its $300 by June 1, a Delaware C-Corp files and pays by March 1. A registered agent with a physical Delaware address is mandatory for either.

Sales tax and state nexus follow the customer, not your formation state

Choosing a no-income-tax formation state does not shield a SaaS company from collecting sales tax where its customers sit. After the Supreme Court’s Wayfair decision, an economic-nexus threshold like “more than $100,000 of goods or services” or “200 or more separate transactions” into a state pulls a remote seller into that state’s sales tax, and roughly half of states tax SaaS. Income and franchise tax follow activity too. California is the sharp example: any LLC “doing business” in California owes the $800 minimum franchise tax, and the state treats the company as doing business if “any of the LLC’s members, managers, or other agents performs activities in California on behalf of the LLC, regardless of where the LLC otherwise conducts business.” Formation state sets your maintenance cost; activity sets your tax exposure.

One filing that is no longer a filing: FinCEN BOI

Older checklists tell you to file beneficial-ownership information within 30 or 90 days. That is wrong for 2026. The March 2025 interim final rule removed the duty for US-formed companies:

“all entities created in the United States… and their beneficial owners will be exempt from the requirement to report BOI to FinCEN.”

The dividing line is where the entity is formed, not the owner’s nationality, so a Ukrainian forming a Delaware or Wyoming LLC in 2026 has no BOI filing obligation. One caution: as of mid-2026 the rule is still labelled interim and was not finalized, so confirm it has not changed before you rely on it.

Filing	Who	2026 date	Penalty for missing
Form 5472 + pro-forma 1120	Foreign-owned LLC (and 25% foreign-owned C-Corp)	April 15 (ext. to ~Oct 15)	$25,000 flat, no cap
Form 1065	Multi-member LLC	March 16 (15th falls on a Sunday)	Per-partner penalties
Form 1120	C-Corp	April 15	Standard
Delaware LLC tax ($300)	Delaware LLC	June 1	$200 + 1.5%/month
Delaware franchise tax + report	Delaware C-Corp	March 1	$200 + 1.5%/month
FinCEN BOI	US-formed entities	Not required	n/a

Stripe, US banking, and the W-9 question

The common pitch, “form a US LLC and get Stripe plus Mercury remotely,” is half right. Stripe is the soft part. The bank is the wall.

Stripe gates on the business, not on the owner’s home address. Its agreement defines the account country by the business address, and its documents expressly handle an owner who lives elsewhere: when a person linked to the account “resides in a different country than the country of the Stripe account, a valid passport is the only accepted form of ID.” Both caveats come from Stripe’s own rules. Onboard the LLC as a company, not as a sole proprietorship, or you will need a US phone number. And founders located in the occupied regions of Ukraine are blocked outright.

So for a registered US LLC, Stripe is a conditional barrier, not a hard one. Stripe Atlas will form the company, but Atlas itself does not promise payment approval.

The blocker is the US bank account that Stripe pays out to. The two neobanks formation agencies funnel founders toward, Mercury and Relay, both bar Ukraine. Mercury states it is “unable to open accounts for founders living in” a listed set of countries, and that list includes Ukraine. Relay accepts US entities with non-US owners “However, there are a few exceptions per the terms set by our banking partner,” and its prohibited list also names Ukraine. Brex is C-Corp-only, Novo wants a US SSN.

The standard remote-Mercury pitch is contradicted by the bank’s own published policy, and the whole “form an LLC, bank remotely” plan rests on that one assumption being wrong.

What works for the payout leg is narrower. Wise Business opens to a registered US business and gives US account details Stripe can pay into, though it is an electronic money institution, not a bank. Payoneer supports Ukraine directly and fits receivables more than Stripe payouts.

For a SaaS company, a merchant-of-record removes the whole entity-plus-bank-plus-Stripe chain. Paddle “acts as a reseller of your product” and becomes “the ‘seller on record’… responsible for the collection and payment of VAT and tax instead of you.” If card payments were the only reason you wanted the US entity, an MoR may make the entity unnecessary, at the cost of a higher fee.

One procurement trap rarely gets named upfront. A foreign-owned single-member LLC looks like a US vendor on the contract but does not hand a US client the W-9 they may expect. The IRS Form W-9 instructions are explicit: if the owner of a disregarded entity is foreign, the owner must complete “an appropriate Form W-8 instead of a Form W-9,” and this stays true “even if the foreign person has a U.S. TIN.” If a US enterprise client specifically wants a W-9 vendor, a disregarded LLC may not clear that hurdle. Check what your client’s procurement actually requires before you incorporate, not after.

The Ukrainian layer

The US side is the easy half. For a Ukrainian-resident owner the Ukrainian rules decide the outcome. The full mechanics live in the CFC article.

A single-member LLC is still a КІК, even though the US “disregards” it. “Disregarded” is a US tax label, not a company form. Ukrainian law keys CFC status to the company-law status of the entity in its country of registration, and under Delaware or Wyoming law your LLC is a legal entity. So it is a controlled foreign company for you. The “US ignores it” feature gives no Ukrainian relief. If anything it removes your easiest exemption.

That exemption is the effective-rate gate. A CFC’s profit escapes inclusion when there is a tax treaty in force and the company either pays profit tax at an effective rate no more than five percentage points below the Ukrainian base rate, or earns no more than 50% passive income. The treaty condition is always met for a US entity, because the 1994 US-Ukraine Convention is in force. But a single-member LLC pays 0% US corporate tax, so its effective rate is zero and it fails the rate gate, exactly like an Estonian OÜ. Its exemption then rests only on the active-income limb (passive income under 50%) or on the unconditional floor where one controller’s total CFC income stays under the equivalent of €2 million.

A C-Corp paying 21% can clear the gate, but the test is the tax actually paid divided by pre-tax profit, so a C-Corp whose income is mostly untaxed in the US would still fail.

A sharper risk sits beyond CFC tax: the LLC can become a Ukrainian tax resident through place of effective management. Ukraine treats itself as the place of effective management if executive decisions and current operations are made mainly from Ukraine, and a tie-breaker turns on where the company’s bank accounts, accounting, and staff are managed. A nominee registered agent or a paper US manager does not protect a Kyiv founder, because the test looks at actual management “regardless” of formal authority.

If you run the bank account and sign the deals from a Kyiv desk, the same facts that make you a controlling person feed an argument that the US entity is a Ukrainian corporate taxpayer. Then the foreign wrapper buys nothing. The fix is the standard one: keep the Ukrainian team on a Ukrainian entity that sells to the US entity at arm’s length.

One genuinely US-specific point on visibility. The US is the one common CFC jurisdiction that does not feed Ukraine’s CRS pipeline; the US is not a CRS party. Ukraine’s automatic line of sight into US accounts runs only through the FATCA agreement, which is structurally one-directional. This is not a reason to under-report. The КІК notification and annual report are mandatory regardless, and the tax service issues information requests. It is simply an accurate note that the detection mechanics differ from CRS countries.

For the C-Corp dividend case, the treaty rates are levers, but read them carefully. Dividends to a Ukrainian beneficial owner are capped at “5 percent of the gross amount of the dividends, if the beneficial owner is a company that owns at least 10 percent of the voting stock” and “15 percent of the gross amount of the dividends in all other cases.” An individual Ukrainian founder holding C-Corp shares directly gets 15%, not 5%. The 5% rate requires a company holder. Interest is taxed only in the residence state, so 0% at source, and royalties are capped at 10%, including for computer programs. To claim any reduced rate the owner hands the US payer a Form W-8BEN; a Ukrainian tax number satisfies the TIN requirement, so a US ITIN is not strictly needed. Without a valid W-8BEN the payer withholds the full 30%.

$100,000 of profit, traced to the founder’s pocket

What a structure costs in tax is measured in your pocket, after both jurisdictions take their share, not at the US headline rate. This traces $100,000 of pre-tax profit for a Ukrainian-resident individual founder who wants the cash personally. The figures are illustrative, built on the rates above, and the 5% Ukrainian military levy is never covered by a foreign credit, so it is always due. Distributing the CFC’s profit before the annual return is filed taxes it at 9%; leaving it in the company taxes the undistributed profit at 18%.

Scenario	US tax	Ukrainian owner tax	Net to founder	Effective total
A. Single-member LLC (active), distribute	$0	9% PIT + 5% levy if distributed before filing	≈ $86,000	≈ 14%
B. Single-member LLC (active), retain	$0	$0 while the active-income exemption holds	$100,000, stays in the LLC	≈ 0%, but not in pocket
C. Single-member LLC (passive, not exempt), retain	$0	18% PIT + 5% levy on undistributed profit	≈ $77,000, still in the LLC	≈ 23% now, more on extraction
D. Delaware C-Corp, distribute dividend	21% corp, then 15% treaty withholding	9% PIT credited by the US withholding, 5% levy always due	≈ $63,000	≈ 37%
E. ФОП third group, no US entity	n/a	~6% (5% єдиний податок + 1% military levy) plus fixed ЄСВ	≈ $94,000	≈ 6%

Read the table plainly. For getting cash into a Ukrainian founder’s pocket, a US entity is not a tax win. A plain third-group ФОП beats every US structure. The single-member LLC only makes sense when you need the US face or Stripe, and you still pay the Ukrainian dividend layer when you extract.

The C-Corp is the most expensive of all, stacking 21%, 15%, and 5%, and is justified by a venture round, never by tax. Holding the C-Corp through a company rather than personally cuts the 15% dividend rate to 5%. The two swing variables to model are whether the active-income exemption actually holds, which needs real substance, and whether the €2 million floor covers you regardless.

The operating model that survives a review

The structure that survives a Ukrainian tax review keeps Ukrainian delivery visible and lets the US entity own a real US-facing function. Moving Ukrainian delivery into a US wrapper does the reverse, and a review will see it. Three patterns, worst to standard:

1. The US entity hires or contracts the Kyiv team directly. The Ukrainian staff deliver the service the US entity invoices, which is a permanent-establishment fact pattern, and if they sign deals it is an agency PE. It also feeds the place-of-effective-management argument. The “US” revenue gets re-taxed in Ukraine. Avoid this.
2. The team stays on a Ukrainian entity (ТОВ or Diia.City); the US entity buys services from it at arm’s length. People are employed domestically, the US entity is a real customer, and talent retention and reservation stay in Ukraine. This needs transfer-pricing discipline and a genuine intercompany agreement, but it keeps the PE and management lines clean.
3. Relocation or an EOR. Only when people actually move.

For a solo or sub-30 founder the practical version uses ФОПи. The US LLC bills the global clients, then buys development from the founder’s and each team member’s third-group ФОП at arm’s length, and each ФОП books the income at 5% єдиний податок plus 1% military levy. Ukraine takes no withholding on that inbound payment, because a foreign company paying a Ukrainian ФОП is not a Ukrainian tax agent; the ФОП self-declares.

The price between the ФОП and the related LLC must be defensibly arm’s length, with a real business purpose. And owning the LLC gives the ФОП regime no shelter from the personal КІК duties: the 60-day notification and the annual report still apply.

Two structural limits to plan around. Formal transfer-pricing obligations attach once controlled transactions cross 150 million UAH of annual income and 10 million UAH per counterparty; a 30-to-100 person agency selling most of its work to its own US entity can hit those thresholds, and a token markup is weak evidence. And funding the US entity from Ukraine runs into currency control: an individual’s outbound investment and lending sits under a €200,000 annual e-limit, and accumulated Ukrainian cash cannot be swept abroad freely even though new foreign revenue can land in the US entity directly.

What it really costs per year

Use ranges, not a fake precise total. The government fees are fixed facts; the service-provider prices are what those vendors advertise, not a market rate.

The honest recurring floor most founders actually pay is the state annual fee, a registered agent, a Form 5472 preparation fee, and the Ukrainian CFC report. The state fee runs from $0 in New Mexico to roughly $60 in Wyoming to $300 in Delaware. Registered agents are commonly around $100 to $125 a year. The 5472 plus pro-forma 1120 preparation is the swing item, and practitioner rates span a wide band: budget preparers advertise figures starting around $450, while full CPA firms quote from around $1,500. No official price exists for either the US preparation or the Ukrainian CFC report, so treat those as practitioner estimates, not facts.

Three tiers, roughly:

• Do it yourself: about $110 to $285 in year one for the state fee, a free phone or fax EIN, and an optional agent. Recurring cost climbs to roughly $400 to $900 once you pay someone for the 5472 work.
• Done-for-you formation: about $400 to $900 in year one. Stripe Atlas advertises a “$500 one-time setup fee” that includes government fees and a first year of registered agent, then “$100 annually” after. Recurring formation-only upkeep is roughly $100 to $300.
• Done-for-you including tax and bookkeeping: roughly $1,500 to $3,000 a year on agency rate cards, bundling the 5472 preparation, the agent, and a US address.

A Delaware C-Corp costs materially more, adding a full Form 1120, the franchise tax (near $400 if you use the Assumed Par Value method, much higher if you do not), the $50 annual report, and US tax advisory. That cost is justified by fundraising, not by tax. The “$0 LLC” and “$500 setup” advertisements hide the two lines you actually pay every year: the 5472 preparation and the Ukrainian CFC report.

Plan the exit before the entry

Closing the entity is cheap on paper and expensive in tax. A Delaware LLC files a Certificate of Cancellation, and all franchise tax must be paid first. You also file a final Form 5472 and pro-forma 1120 for the closing year. On the Ukrainian side the tax-free CFC-liquidation window closed at the end of 2021, so liquidation proceeds to the owner are taxable foreign income, and the disposal triggers a 60-day КІК notification.

The mistake to avoid is walking away from an unused LLC without liquidating it. A dormant entity keeps generating the Form 5472 duty, and with it the $25,000 exposure, every year it exists. If the structure stops earning its keep, close it deliberately.

US LLC versus Estonian OÜ, and when each fits

For a Ukrainian owner the US LLC and the Estonian OÜ are structural twins. Both pay no entity-level tax that clears the Ukrainian 13% gate, so both fail it and lean on the active-income exemption or the €2 million floor. Both leave the Ukrainian layer deciding the real tax. The difference is what they unlock commercially. The US entity wins when you need US clients, Stripe and US card rails, or US investors. The Estonian entity wins for EU contracting and EU payment rails, and its retained-profit regime defers tax cleanly until distribution. Neither is a tax shelter for cash you want in your pocket this year.

A US entity fits when	A US entity does not fit when
US procurement demands a US payee	Your buyers are EU clients happy with a ТОВ or OÜ
A SaaS product needs Stripe or US card acquiring	The goal is to lower your personal tax
You are raising from US VCs	You only want a foreign bank account
The business has real US operations	A merchant-of-record already solves payments

The bottom line

A US company is a market tool, not a tax tool. It gives a Ukrainian IT business a US contracting face, Stripe and US card rails, and the Delaware C-Corp investors expect. It does not lower a Ukrainian-resident owner’s tax, it adds a $25,000-risk US filing and a second set of state obligations, and the LLC remains a КІК with the Ukrainian layer still deciding the bill. Price both jurisdictions before you form anything, design the operating model so the Ukrainian team and the US entity sit cleanly apart, and keep the ФОП. Form the US entity for the job only it can do, and not a day before you need it.
