Who This Applies To

• A non-U.S. individual or foreign company owns a U.S. single-member LLC.
• Two or more foreign persons own a U.S. multi-member LLC.
• Foreign shareholders own a U.S. C corporation.
• The owners and personnel perform most or all services outside the United States.
• Customer receipts are collected through Stripe, PayPal, a U.S. bank account, or another payment platform.
• The entity receives owner funding, makes withdrawals, or sends money to an owner-controlled foreign company.
• A corporation is dormant, pre-revenue, or has only startup and maintenance costs.
• A formation agency, consultant, or centralized coordinator is assembling annual tax records for multiple foreign founders.

Core rule
The legal form and federal tax classification determine the entity-level filing. A foreign-owned domestic single-member LLC is generally disregarded for ordinary income tax but treated as a separate corporation for limited Section 6038A reporting. A domestic multi-member LLC generally files as a partnership unless it elected corporate treatment. A U.S. C corporation is a separate domestic taxpayer. After classifying the entity, separately determine who earned the income, where the activity occurred, whether a foreign person conducted a U.S. trade or business, whether income is effectively connected, and which related-party reporting and withholding rules apply.

Frequently Asked Questions

1. Which federal return does the entity file?

Start with the number of owners and any entity-classification election—not the bank account or the owners’ residence.

One-owner domestic LLC. A domestic eligible entity with one owner is generally disregarded unless it elected corporate treatment. Its business income is ordinarily reported by its owner, while a foreign-owned disregarded entity may have a separate Form 5472 obligation.

Two-or-more-owner domestic LLC. A domestic eligible entity with at least two members generally defaults to partnership treatment and files Form 1065 unless it elected corporate treatment.

Domestic corporation. A corporation formed under U.S. law generally files Form 1120 unless a special corporate return applies.

---

2. What does a foreign-owned U.S. single-member LLC generally file?

For ordinary income tax, the LLC is generally disregarded and its activity is attributed to the foreign owner. For Section 6038A reporting, however, a domestic disregarded entity wholly owned by a foreign person is treated as a separate domestic corporation.

When the LLC has a reportable transaction, it generally files Form 5472 with a limited pro forma Form 1120. The pro forma return is only a transmittal mechanism; it does not elect C-corporation treatment and does not replace any Form 1040-NR or Form 1120-F required from the owner.

---

3. Does every foreign-owned single-member LLC file Form 5472 every year?

No. The current instructions provide an exception when the foreign-owned disregarded entity had no reportable transaction during the year. But “no revenue” and “no reportable transaction” are not the same.

A pre-revenue or dormant LLC may still have owner funding, owner-paid fees, withdrawals, loans, reimbursements, formation activity, or dissolution transactions. Reconstruct those items before concluding that no Form 5472 is required.

---

4. Which owner and related-party transfers must be identified?

Common transactions include owner contributions, cash or property distributions, loans and repayments, owner-paid LLC expenses, reimbursements, personal expenses paid by the LLC, services between related parties, and amounts connected with formation or dissolution.

A transfer to the foreign owner may be compensation, repayment of an owner loan, reimbursement, or another transaction. The purpose, documentation, and accounting entry should determine the classification.

A transfer to a foreign company controlled by the same owner can involve a separate related party. Identify that company and characterize the payment as a service fee, purchase, royalty, loan, repayment, reimbursement, or distribution routed through another entity. A separate Form 5472 is generally required for each related party with whom reportable transactions occurred.

---

5. Does the disregarded LLC need a full profit-and-loss statement and balance sheet?

The narrow Form 5472/pro forma Form 1120 filing does not require the LLC to complete a normal corporate income statement and balance sheet. The pro forma Form 1120 contains only the identifying items specified in the Form 5472 instructions.

Reliable records are still required. The file must support contributions, distributions, loans, owner-paid costs, reimbursements, related-company transfers, and the LLC’s income-tax position. A full P&L may also be necessary when the owner could have effectively connected income, inventory activity, state obligations, or foreign-country reporting.

---

6. What does a foreign-owned U.S. C corporation file?

A domestic C corporation generally files Form 1120 whether or not it has taxable income. It reports its own income, deductions, assets, liabilities, shareholder funding, loans, and related-party activity. The regular federal corporate tax rate is currently 21% of taxable income.

The return ordinarily requires a reconciled P&L and balance sheet. The corporation must also test Form 5472 when it is at least 25% foreign owned and has reportable transactions with a related party.

---

7. Is a U.S. corporation tax-exempt because all work and customers are outside the United States?

No. A corporation created under U.S. law remains a domestic corporation and is generally subject to U.S. federal tax on its taxable income. Foreign operations can affect sourcing, foreign tax credits, deductions, and state exposure, but they do not convert the corporation into a foreign entity or eliminate Form 1120.

This is a fundamental difference from a disregarded LLC owned by a nonresident foreign person, where the owner-level U.S. income-tax result depends on the owner’s activities, income source, U.S.-trade-or-business status, and ECI.

---

8. Does a dormant or pre-revenue C corporation still file, and when is Form 5472 required?

The corporation generally still files Form 1120 even when it had no revenue, no customers, only startup costs, or a loss. Review initial capitalization, shareholder loans, organizational costs, registered-agent fees, bank charges, and other activity before describing the company as having “no transactions.”

Form 5472 is separate. A qualifying foreign-owned corporation generally files it only when it had a reportable transaction with a related party. The Form 5472 instructions provide a no-reportable-transaction exception, but that exception does not remove the Form 1120 filing obligation.

---

9. What does a foreign-owned multi-member LLC generally file?

A domestic LLC with two or more genuine members generally files Form 1065 unless it elected corporate treatment. It furnishes Schedule K-1 to each partner and reports income, deductions, assets, liabilities, allocations, and capital information.

The partnership itself generally is not subject to the regular federal income tax imposed on a C corporation; the partners are taxed in their separate capacities. Foreign ownership adds a review of Schedules K-2/K-3, Section 1446 withholding, partner documentation, and partner-level U.S. returns.

---

10. Does a U.S. bank account or Stripe account make foreign-performed services taxable in the United States?

Not by itself. For personal services, source generally follows where the work is physically performed. The client’s country, entity’s formation state, payment processor, currency, and receiving bank account do not ordinarily replace that rule.

Services performed partly inside and partly outside the United States may require a reasonable allocation. U.S. employees, a U.S. office, inventory, or agents with meaningful authority can materially change the U.S.-trade-or-business and ECI analysis.

---

11. When are Schedules K-2 and K-3 relevant?

Schedules K-2 and K-3 report partnership items of international tax relevance. Foreign-partner status makes the analysis particularly important because Part X can provide information needed for Forms 1040-NR, 1120-F, withholding, ECI, and U.S.-source non-ECI income.

For 2025, Part X generally must be completed by every partnership with a foreign partner unless the stated exception applies—generally, no ECI and satisfaction of applicable Chapter 3 and Chapter 4 withholding and reporting obligations. Other domestic-filing and partner-request exceptions must also be tested under the instructions for the actual year.

---

12. When does Section 1446 withholding apply?

Section 1446(a) generally applies when a partnership has effectively connected taxable income and part of that ECTI is allocable to a foreign partner. The withholding base is the foreign partner’s allocable ECTI—not the amount of cash distributed. Withholding can therefore be required even when the partnership retains all of the cash.

Current IRS instructions generally use 37% for noncorporate foreign partners and 21% for corporate foreign partners, subject to preferential-rate and other permitted adjustments. Forms 8813, 8804, and 8805 are used to pay and report the tax.

---

13. Does each foreign owner or partner need Form 1040-NR or Form 1120-F?

Not automatically. A foreign individual may need Form 1040-NR when the individual was engaged in a U.S. trade or business, had ECI, received certain U.S.-source income not fully covered by withholding, or needs to claim a refund. A foreign corporation may need Form 1120-F under its own filing rules.

If a partnership is engaged in a U.S. trade or business, Section 875 generally treats a nonresident alien individual or foreign corporation that is a partner as engaged in that business. The entity return, withholding forms, and partner-level return must therefore be analyzed separately.

---

14. What financial records should a C corporation or partnership provide?

A workable year-end package generally includes a trial balance, P&L, beginning and ending balance sheets, general ledger, bank and credit-card reconciliations, processor statements, accounts receivable and payable, fixed assets, loans, owner or partner capital activity, related-party transactions, payroll, and prior returns.

The statements should reconcile to the underlying bank and processor activity. Estimates, unexplained transfers, and personal transactions should be identified before filing. Organized books with retrievable support are more useful than an uncategorized upload of receipts.

---

15. How should Stripe, PayPal, and other processor activity be reconciled?

Basic processor bridge
Gross customer charges − refunds − chargebacks − processor fees ± reserves, currency adjustments, and timing differences = net transfers to the bank.

The tax return and P&L ordinarily begin with the appropriate gross receipts—not the net cash deposited after platform deductions. Also isolate personal transactions, receipts belonging to another entity, year-end unsettled balances, and transfers to owners or related companies.

---

16. What should be collected before the file is sent to a U.S. tax preparer?

Collect the formation documents, EIN notice, federal classification elections, tax year, ownership history, operating agreement or corporate records, and prior filings. For every owner or partner, collect legal name, address, citizenship or organization country, tax residence, entity type, U.S. and foreign tax numbers, ownership dates, and appropriate Forms W-8 or W-9 when relevant.

Document where services were performed, U.S. offices, employees, agents, warehouses, and inventory; list payment platforms, bank accounts, and related foreign companies; and provide the entity-appropriate financial or related-party transaction records. State income, franchise, sales, and gross-receipts taxes remain separate and must be reviewed based on each state’s nexus rules.

Common Mistakes and the Better Approach

---

Deadlines and Penalty Exposure

Form 1120 and the Foreign-Owned Disregarded-Entity Package

A corporation generally files by the 15th day of the fourth month after year-end. A foreign-owned disregarded entity’s Form 5472/pro forma Form 1120 package follows the applicable Form 1120 due date and special filing procedure. A timely Form 7004 generally extends the filing period, but not payment obligations.

Form 1065

A partnership generally files by the 15th day of the third month after year-end. Form 7004 must generally be filed by the regular due date to obtain the ordinary extension.

Form 5472 Penalty

Failure to file a required Form 5472 timely and in the prescribed manner can trigger an initial $25,000 penalty. A substantially incomplete filing can be treated as a failure, and additional $25,000 continuation penalties can apply after IRS notice if the failure continues beyond the statutory period.

Form 1065 and Partner-Statement Penalties

For returns required to be filed in 2026, the 2025 Form 1065 instructions state a late-filing penalty of $255 per partner for each month or part of a month, up to 12 months. They also state a $340 penalty for each late, incomplete, or incorrect Schedule K-1 and Schedule K-3, subject to limits, intentional-disregard rules, and reasonable cause. Use the amount applicable to the return’s actual due date.

Section 1446

Form 8813 installments generally fall in the fourth, sixth, ninth, and twelfth months of the partnership year. Forms 8804 and 8805 generally use the third-month annual filing cycle. Extending the return does not ordinarily extend the time to pay the withholding tax.

Practical Examples

Example 1 — Foreign-owned single-member LLC with owner transfers

A foreign individual owns a U.S. disregarded LLC and performs all consulting work abroad. During the year, the owner contributes $10,000, pays several LLC expenses personally, and later transfers $15,000 from the LLC account to a personal foreign account. The LLC reviews and reports the owner transactions on Form 5472 when required. The U.S. account does not itself make the service income U.S.-source; the owner-level Form 1040-NR question is analyzed separately.

Example 2 — Foreign-owned C corporation with no sales

Foreign shareholders form a U.S. C corporation, capitalize it, and incur organizational, software, and registered-agent costs but no customer revenue. The corporation generally still files Form 1120. It separately tests whether shareholder funding, loans, or other related-party items require Form 5472.

Example 3 — Two foreign partners perform consulting abroad

Two nonresident individuals own a domestic LLC taxed as a partnership. They perform all services from their home countries, have no U.S. office or personnel, and collect payments through Stripe and a U.S. bank. The LLC generally files Form 1065 and K-1s. Whether Section 1446 or Forms 1040-NR apply depends on the U.S.-trade-or-business and ECI analysis—not the bank location. K-2/K-3 must also be tested under the current instructions.

Example 4 — Payment to an owner-controlled foreign company

A foreign-owned disregarded LLC sends monthly amounts to a foreign company controlled by the same owner. The file should establish whether the payments are service fees, royalties, purchases, loans, repayments, reimbursements, or distributions. The foreign company may be a separate related party requiring its own Form 5472.

• Whether the entity had state income, franchise, sales, or gross-receipts tax nexus.

Decision Sequence

1. Confirm the legal entity and federal tax classification.
2. Identify every owner, shareholder, and partner, including ownership dates and entity type.
3. Confirm each person’s U.S. and foreign tax residence and taxpayer identification numbers.
4. Map where services, management, employees, offices, inventory, and fulfillment were located.
5. Reconcile bank, credit-card, and payment-processor activity.
6. Prepare the entity-appropriate P&L, balance sheet, and capital or shareholder schedules.
7. Reconstruct owner, partner, shareholder, and related-company transactions.
8. Determine source, U.S.-trade-or-business status, and effectively connected income.
9. Prepare the entity return, international schedules, and withholding forms.
10. Determine each foreign owner’s or partner’s separate U.S. return and review state and foreign-country obligations independently.

Closing

Foreign-owned U.S. entities do not share one filing system. A disregarded single-member LLC, a multi-member LLC taxed as a partnership, and a domestic C corporation can have different returns even when their owners, customers, payment processors, and foreign operations appear similar.

The reliable approach is to classify the entity first, map where the business activity occurred, reconcile the books, and trace every owner and related-party transfer. A U.S. bank or Stripe account does not independently create U.S. taxable income, while the absence of U.S. operations does not eliminate Form 1120, Form 1065, or Form 5472 when their separate filing conditions are met.

Accurate financial statements, transaction records, and partner or shareholder information allow the entity return, international reporting, withholding, owner-level filings, and state obligations to be determined under their own rules rather than by assumption.
