Foreign-Owned US Companies: How to Keep Intercompany, FX, and IRS Reporting Under Control

A foreign parent has several ways to move cash from a US subsidiary.

For a foreign parent with a US subsidiary, LLC, or US branch, three areas need to work together:

1. Intercompany accounting
2. Foreign-currency and FX accounting
3. IRS compliance

Every transaction between the US entity and its foreign parent or related companies should be separately identifiable, properly recorded, supported, reconciled, and reported.

The exact accounting and tax reporting requirements depend on how the foreign company operates in the US.

The US operation may be:

• A US C corporation
• A foreign-owned single-member LLC
• A US partnership
• A foreign corporation operating directly in the US through a branch

Each structure has different accounting, tax filing, intercompany, and reporting requirements. Understanding the structure is the first step to knowing what needs to be reported and how.

 

1. Keep Intercompany Transactions Separate

One of the most common problems is putting everything into one account called "Due to Parent."

That makes it difficult to determine what the balance actually represents.

Instead, track intercompany activity by legal entity, related party, and transaction type.

 

Common Intercompany Transactions

Transaction	US accounting	Documentation
Capital contribution	Equity / additional paid-in capital	Corporate approval, contribution notice, bank record
Intercompany loan	Loan payable or receivable	Loan agreement, interest rate, maturity, repayment schedule
Cash advance	Short-term due to/from affiliate	Cash-pool agreement and activity schedule
Management fee	Expense / intercompany revenue	Service agreement, allocation calculation, invoice
Shared-cost recharge	Expense or reimbursement	Vendor support and allocation methodology
Royalty or IP fee	Royalty expense/income	License agreement and royalty calculation
Interest	Interest expense/income	Loan agreement and amortization schedule
Inventory purchase or sale	Inventory, COGS, or revenue	Purchase order, invoice, shipping records
Dividend or distribution	Equity reduction	Corporate approval, E&P and withholding analysis

The more clearly these transactions are separated in the accounting system, the easier it is to prepare the tax returns and respond to questions later.

 

2. Reconcile Intercompany Accounts Every Month

Do not wait until year-end to reconcile the US entity to the foreign parent.

Before closing each month:

1. Reconcile each balance by named related party.
2. Match invoice numbers, dates, currencies, and amounts.
3. Separate principal, interest, service fees, royalties, reimbursements, and capital.
4. Investigate timing differences and missing transactions.
5. Identify FX differences.
6. Confirm the balance with the parent or related company.
7. Prepare the elimination entries needed for group consolidation.

A simple intercompany schedule can look like this:

Counterparty	Account	Opening Balance	Current Activity	Cash Settlement	FX	Closing Balance
Foreign Parent	Intercompany loan
Foreign Parent	Management fees
Affiliate A	Inventory payable
Affiliate B	Royalty payable

This schedule becomes useful for both financial reporting and tax compliance.

 

3. Document Management Fees and Other Parent Charges

A foreign parent may provide services to its US subsidiary.

For example:

• Executive management
• Finance and treasury
• IT
• Cybersecurity
• Human resources
• Procurement
• Legal and compliance
• Technical support
• Regional marketing

But the US company should not simply record an annual "head office allocation" with no supporting detail.

Keep:

• The intercompany agreement
• A description of the services
• Evidence that the US company received a benefit
• The allocation method
• Supporting calculations
• Any markup methodology
• Invoices
• Payment records

The allocation might be based on factors such as:

• Headcount
• Revenue
• Number of users
• Transaction volume
• Time spent
• Actual usage

The exact method should reflect the type of service and the facts of the business.

Good documentation helps support both the accounting and the tax treatment of the charge.

 

4. Understand Functional Currency

Functional currency is not simply the currency used by the foreign parent.

It is the currency of the entity's primary economic environment.

For example, a US operating subsidiary that:

• Sells primarily in US dollars
• Pays employees in US dollars
• Pays US vendors in US dollars
• Maintains US dollar bank accounts

may have the US dollar as its functional currency.

Under US GAAP, functional currency is determined based on the facts and circumstances under ASC 830.

 

Three Currencies to Keep Straight

Currency	Purpose	Typical treatment
Transaction currency	Currency used for an invoice, loan, or payment	Initially recorded using the transaction-date exchange rate
Functional currency	Currency of the entity's primary economic environment	Used for the entity's books and financial reporting
Reporting currency	Currency used by the foreign parent for consolidation	US financial statements are translated into the parent's reporting currency

These are not necessarily the same currency.

 

5. Example: Foreign-Currency Loan

Assume:

• The US subsidiary's functional currency is USD.
• The foreign parent lends the subsidiary €500,000.
• The loan remains denominated in euros.

When the US company receives the loan, it records the liability using the applicable USD exchange rate on the transaction date.

At each month-end, the outstanding euro balance is remeasured using the applicable closing exchange rate.

The resulting change can create a foreign-exchange gain or loss in the US company's books.

When the loan is repaid, the company also needs to account for the difference between the carrying amount and the amount of US dollars required to settle the euro obligation.

The foreign parent may then have a different accounting result when it consolidates the US subsidiary into its own reporting currency.

 

6. Do Not Assume Book FX and Tax FX Are the Same

Foreign-currency accounting and US tax reporting do not always produce the same result.

Certain foreign-currency transactions can create US tax gain or loss under Section 988.

Potential differences can arise from:

• Functional currency
• Timing
• Loan terms
• Hedging
• Settlement dates
• Tax versus book treatment

For that reason, the tax team should review significant foreign-currency balances rather than simply using the book FX gain or loss as the tax amount.

 

7. Start IRS Compliance With the US Entity Type

The first question should always be:

What is the US entity for federal tax purposes?

US structure	Common federal filing	Key foreign-parent issue
US C-corporation owned by foreign parent	Form 1120	Form 5472 and related-party reporting when applicable
Foreign-owned single-member LLC disregarded for tax	Pro forma Form 1120 with Form 5472	Related-party reporting, including certain contributions and distributions
US LLC taxed as partnership	Form 1065	Foreign-partner reporting and withholding considerations
Foreign corporation operating directly in the US	Form 1120-F	Effectively connected income, branch issues, and related-party reporting
US subsidiary making payments to foreign parent	Form 1120 plus applicable information returns	Withholding and reporting for dividends, interest, royalties, services, and other payments

The filing requirements can vary significantly based on the structure.

 

8. Form 5472 Should Be Built Into the Accounting Process

Form 5472 reports certain transactions between a reporting corporation and related parties.

It can apply to transactions such as:

• Inventory purchases and sales
• Services
• Management fees
• Royalties
• Rent
• Commissions
• Interest
• Loans
• Loan repayments
• Certain insurance transactions
• Capital contributions
• Distributions

For a foreign-owned US business, the accounting system should make it possible to identify these transactions by related party and transaction type.

A good setup includes:

• An intercompany dimension
• Separate loan accounts
• Separate interest accounts
• Separate royalty accounts
• Separate management-fee accounts
• Separate inventory accounts
• Separate capital contribution accounts
• Separate distribution accounts

This makes Form 5472 preparation much easier.

A failure to properly file Form 5472 can result in a $25,000 penalty, with additional penalties possible when the failure continues after IRS notice.

 

9. US Branches Have a Different Reporting Structure

A foreign parent may operate directly in the US instead of creating a separate US subsidiary.

In that case, the foreign corporation may have a US branch.

Form 1120-F is generally the main federal income-tax return for a foreign corporation engaged in a US trade or business.

The accounting system should be able to identify:

• US revenue
• US expenses
• Effectively connected income
• US assets and liabilities
• Head-office allocations
• Branch funding
• Interest expense
• Inventory
• Payroll
• Fixed assets
• Related-party transactions

A branch structure can create different tax issues from a US subsidiary, so the accounting system needs to reflect the actual legal and tax structure.

 

10. Review Withholding Before Making Payments

Before the US company pays a foreign parent or affiliate, identify exactly what the payment is.

It could be:

• A dividend
• Interest
• Royalty
• Service fee
• Reimbursement
• Loan repayment
• Other related-party payment

Then review:

• The appropriate Form W-8
• Beneficial ownership
• Tax treaty eligibility
• Limitation-on-benefits requirements
• Applicable withholding rate
• Form 1042 requirements
• Form 1042-S requirements

Do this before the payment is made.

Fixing a withholding mistake after the money has already left the US can be much more difficult.

 

11. Build a Monthly Reporting Package

For a foreign-owned US company, I recommend maintaining a monthly package that includes:

• US trial balance in USD
• Parent reporting-currency trial balance
• Translation schedule
• P&L
• Balance sheet
• Cash flow
• Budget versus actual
• Intercompany matrix
• Intercompany confirmations
• Loan and interest schedule
• FX gain/loss schedule
• Related-party transaction schedule
• Tax payment calendar
• Payroll tax status
• Sales tax status
• Open compliance issues

This gives the foreign parent and the US accounting team one consistent set of information.

 

12. Put Basic Controls in Place

A few simple controls can prevent many problems.

Before recurring charges begin

Require a signed agreement for:

• Management fees
• Service charges
• Royalties
• Loans
• Cash-pooling arrangements

During the month

Code related-party transactions when they are recorded.

Do not wait until year-end to figure out which transactions were with related parties.

During month-end close

Require review and approval of intercompany reconciliations.

Before filing tax returns

Reconcile the Form 5472 workpapers to:

• The final general ledger
• Intercompany schedules
• Bank activity
• Parent confirmations
• The tax return

Keep the support

Maintain:

• Contracts
• Invoices
• Bank records
• Wire confirmations
• Allocation calculations
• FX rate support
• Tax forms
• Reconciliation schedules

Keep these records in one organized electronic file.

 

The Goal: One Number Should Tell the Whole Story

A good foreign-owned US accounting system should allow a reviewer to start with a number on the tax return and trace it back to the accounting records.

For example:

Form 5472 → related-party schedule → general ledger → invoice or agreement → bank payment → parent confirmation

If you can follow that trail, the accounting and tax records are much easier to support.

If you cannot, the problem usually starts before tax preparation. It starts with how intercompany transactions were recorded and documented during the year.
