The Capital Relocation Framework
You are about to wire money into your U.S. company, or take money out of it, and the wire itself will not tell anyone what it was. Someone will decide later. The useful discipline is this: every dollar that crosses the U.S. boundary has a character, the character is fixed by the substance and the paperwork behind the transfer, and the character determines the tax treatment, the withholding, and the reporting that follows.
The question that governs everything
Before a transfer happens, answer one question. What is this payment, in the language the Code uses? Capital contribution, loan advance, repayment of principal, interest, dividend, return of capital, royalty, service fee. That list is close to exhaustive for a closely held cross-border structure, and each item answers differently on whether it is income, whether it is deductible, whether anything must be withheld, and what gets filed.
Deciding afterward is where the cost lives. A transfer with no note and no agreement becomes whatever the facts support on examination, and the only fact at that point is a bank statement.
Money in: two routes
Contribution
A transfer of cash or property to a U.S. corporation solely in exchange for stock is generally covered by IRC §351, which provides nonrecognition where the transferors are in control immediately afterward, control being defined by IRC §368(c). A contribution to capital by an existing shareholder without new stock issued falls under IRC §118, which excludes it from the corporation's gross income, subject to the exclusions §118(b) added for governmental entities and civic groups. Where the U.S. entity is an LLC treated as a partnership, the analogous provision is IRC §721.
Money arriving as a contribution is not income to the U.S. company and nothing is withheld. What it creates is basis, and basis is what you will want documented when capital comes back out years later.
Loan
An advance documented as a loan creates a payable rather than equity. Interest is deductible by the U.S. company, subject to the limitation at IRC §163(j) and to the timing rule at IRC §267(a)(3) and Treas. Reg. §1.267(a)-3, which generally defers a deduction for an amount owed to a related foreign person until it is paid. Repayment of principal is not income to the lender and is not subject to withholding. That last point is why loans are attractive, and why they are examined.
Why the label on the way in is not self-executing
Calling an advance a loan does not make it one. IRC §385 authorizes regulations distinguishing debt from equity. The minimum documentation regulations issued under Treas. Reg. §1.385-2 were removed by T.D. 9880, published November 4, 2019, so no checklist guarantees the outcome. Treas. Reg. §§1.385-1, 1.385-3 and 1.385-4 remain.
What is left is the ordinary factual inquiry: a written instrument, a stated maturity, a stated rate, a creditor's remedies on default, and a repayment history that resembles the instrument. If the advance is recast as equity, the interest deduction disappears and the payments called interest become distributions, with a different withholding character. Do the paperwork at the time of the advance. Retroactive notes are the weakest document in the file.
Money out: four characters, four treatments
Once the U.S. entity pays a foreign person, the source rules decide whether the payment is U.S.-source at all, and the character decides what happens to it.
| Payment | Source rule | Statutory withholding | Deductible by the U.S. payer |
|---|---|---|---|
| Dividend | U.S.-source when paid by a domestic corporation, IRC §861(a)(2)(A) | 30%, treaty may reduce | No |
| Interest | Sourced by the residence of the payer, IRC §861(a)(1) | 30%, treaty may reduce, portfolio interest exception may apply | Yes, subject to §163(j) and §267(a)(3) |
| Royalty | Sourced where the property is used, IRC §861(a)(4) | 30%, treaty may reduce | Yes, priced under §482 |
| Service fee | Sourced where the services are performed, IRC §861(a)(3) and §862(a)(3) | None where the services are performed outside the United States, because the income is foreign-source | Yes, priced under §482 |
The service fee row is the one that changes behavior. Work done by people physically outside the United States produces foreign-source income, and withholding on fixed, determinable, annual or periodical income reaches U.S.-source amounts. That position depends on evidence of where the work was performed: a services agreement describing the work, and records showing who did it and from where. It does not depend on where the invoice was issued or where the bank account sits.
A fifth item belongs on the list and is not income at all. Repayment of loan principal returns the lender's own money, but it needs a loan balance schedule showing principal against interest, because a payment that cannot be traced to a principal balance will not be treated as one.
Distributions in excess of earnings and profits are a related trap. IRC §301(c) treats a corporate distribution as a dividend to the extent of earnings and profits, then as a reduction of basis, then as gain. Treas. Reg. §1.1441-3(c) holds the withholding rules for corporate distributions, including a rule addressing underwithholding caused by underestimating earnings and profits. Calling a distribution a return of capital does not by itself remove the withholding obligation. The earnings and profits computation has to exist.
The machinery that does the withholding
IRC §1441 imposes withholding on payments of U.S.-source fixed, determinable, annual or periodical income to nonresident alien individuals, foreign partnerships and foreign fiduciaries. IRC §1442 applies the same rules to foreign corporations. The statutory rate is 30%.
IRC §1461 makes the withholding agent liable for the tax required to be withheld. That is what turns an administrative step into real exposure. If the U.S. company pays 100 gross where 30 should have been withheld, the company owes the 30, and recovering it from the recipient is a commercial problem rather than a tax remedy.
Two adjacent regimes catch structures that are not corporations. Where the U.S. entity is an LLC treated as a partnership with foreign partners, IRC §1446(a) requires withholding on effectively connected taxable income allocable to those partners, at 37% for non-corporate partners and 21% for corporate partners, reported on Forms 8804 and 8805. IRC §1446(f) requires a transferee to withhold 10% of the amount realized on a transfer of a partnership interest by a foreign partner, subject to exceptions. And IRC §1445 requires withholding on the disposition of a U.S. real property interest by a foreign person, reported on Forms 8288 and 8288-A.
The documentation each route depends on
Every reduction from 30% depends on a document that exists before the payment, not after it.
Treaty rate. A foreign entity claims a treaty rate on Form W-8BEN-E, Part III, naming the treaty country, the article relied on and the rate, and supplying a foreign taxpayer identification number. Individuals use Form W-8BEN. The form goes to the withholding agent, not to the Internal Revenue Service. Without a valid form in hand at the time of payment, the withholding agent's correct position is the statutory rate. Where a treaty position overrides or modifies a Code provision, IRC §6114 requires disclosure on Form 8833, and IRC §6712 sets the penalty at $1,000, or $10,000 for a C corporation.
Portfolio interest. IRC §871(h) and §881(c) exempt qualifying portfolio interest from the 30% tax, on specific conditions. The obligation must be in registered form under §871(h)(2)(B)(i) and §881(c)(2)(B)(i), and the payer must receive a statement that the beneficial owner is not a United States person, ordinarily satisfied by a Form W-8. The exception does not reach interest received by a 10-percent shareholder under §881(c)(3)(B) and §871(h)(3), contingent interest under §871(h)(4), interest received by a controlled foreign corporation from a related person under §881(c)(3)(C), or bank loans made in the ordinary course under §881(c)(3)(A).
Read the 10-percent shareholder exclusion carefully, because it removes the exception from the most common structure. Where a foreign parent lends to its own U.S. subsidiary, the parent is a 10-percent shareholder and portfolio interest treatment is not available. The route to a reduced rate there is the treaty, if one applies and the limitation on benefits article is satisfied.
Everything else. A contribution needs a board or member resolution and a basis schedule. A loan needs a note. A royalty needs a license. A service fee needs a services agreement and records of where the work was done.
An illustration ties the threads together. A foreign parent funds its U.S. subsidiary with $600,000 of equity and a $400,000 note at 7%. All figures are illustrative. In year two the subsidiary pays $28,000 of interest and a $100,000 dividend. The interest is U.S.-source under §861(a)(1), and portfolio interest treatment is unavailable because the lender owns the borrower, so absent a treaty $8,400 is withheld. The dividend is U.S.-source under §861(a)(2)(A), and absent a treaty $30,000 is withheld. The interest is deductible subject to §163(j) and only when paid under §267(a)(3). The dividend is not deductible at all. A later $150,000 repayment of principal is not income and nothing is withheld, provided the loan schedule supports it.
What gets reported, and when
Amounts subject to withholding are reported on Form 1042, the annual withholding tax return, and on Form 1042-S per recipient and income code, transmitted with Form 1042-T where filed on paper. Both are due March 15 of the year following the calendar year of payment, moving to the next business day where that falls on a weekend or holiday. Form 7004 extends Form 1042; Form 8809 requests an extension for Form 1042-S. Neither extends the time to deposit tax.
Separately, transfers between the U.S. entity and its foreign related parties are reportable under IRC §6038A on Form 5472, filed with the income tax return by that return's due date including extensions. Where the U.S. entity is a disregarded entity wholly owned by one foreign person, Treas. Reg. §301.7701-2(c)(2)(vi) treats it as a corporation for that purpose, and the filing is a pro forma Form 1120 with Form 5472 attached. Contributions and distributions between the foreign owner and that entity are themselves reportable, which is the point most often missed: moving your own money in and out is a reportable transaction even though it is not a taxable one. The penalty is $25,000 under IRC §6038A(d)(1), plus $25,000 for each 30-day period, or fraction of one, that the failure continues beyond 90 days from IRS notice, per related party, under §6038A(d)(2). IRC §6501(c)(8) keeps the assessment period open until three years after the information is furnished, limited to the related items where the failure was due to reasonable cause and not willful neglect.
Turning this into a policy
Write a one-page capital movement policy and follow it. It needs four things: a list of the permitted characters of transfer for your structure, with the document each one requires; a rule that no transfer is initiated until the character is decided and the document is signed; a single intercompany ledger, maintained monthly, tying every wire to a character and to a running principal or capital balance; and an annual check that the withholding forms on file have not expired, done before the first payment of the year.
The firm's cross-border payments review works through an existing ledger and identifies transfers whose character is unsupported. Broader background sits on the international tax matters page. This article is general information about how these provisions operate, not advice on your facts. Treaty entitlement, entity agreements and loan instruments should be reviewed with your attorney and with an adviser who has seen your documents.
