Intercompany transactions: what a US subsidiary needs to get right

When a foreign parent company funds a US subsidiary, charges it a management fee, or sells it inventory at cost, those transactions don't disappear from an accounting perspective. They become intercompany transactions, and the IRS has specific requirements for how a foreign-owned US corporation tracks, prices, and reports them.

Most international founders launching a US entity for the first time don't know this until something goes wrong. This post covers what intercompany transactions are, what the IRS requires, and what a new US subsidiary needs to set up before money starts moving between entities.

This scenario is drawn from real conversations with Pilot customers.

What is an intercompany transaction?

An intercompany transaction is any exchange of money, goods, or services between two related entities. If your US subsidiary receives a loan from its European parent, that's an intercompany transaction. If the parent company charges the subsidiary a management fee for shared services, that's an intercompany transaction. If the subsidiary buys inventory from the parent at cost, that too is an intercompany transaction.

These are ordinary parts of how multinational businesses operate. They become complicated because the IRS requires that related parties price their transactions as if they were dealing with unrelated third parties. This is called the arm's-length standard, and it's the foundation of transfer pricing rules under IRC §482.

The practical implication: you cannot move money between your US entity and its parent at whatever amount is convenient. Each transaction needs to reflect a price that an independent party would pay.

What does the IRS require a foreign-owned US corporation to file?

A 25 percent or more foreign-owned US corporation must file Form 5472 with the IRS every year, attached to its corporate income tax return. Form 5472 discloses all reportable transactions between the US corporation and its foreign shareholders or related parties.

Reportable transactions include loans, sales of goods, payments for services, rents, royalties, and the use of property. The threshold for disclosure is low; any transaction with a related foreign party must be reported, with limited exceptions.

The penalty for failing to file or for filing an incomplete return is $25,000 per form per tax year. That penalty applies even if the company has no taxable income, even if it's pre-revenue, and even if the failure was unintentional. The IRS treats Form 5472 compliance as a strict-liability requirement: the form is due, or the penalty applies.

For a company that incorporated as a Delaware C-corp in September and started operations in November, that first filing obligation arrives within months of launch.

What does "arm's length" mean in practice for an early-stage subsidiary?

The arm's-length standard requires that any transaction between related parties be priced as if the parties were independent. For a mature company with established products and services, this involves detailed transfer pricing studies. For an early-stage subsidiary, the requirements are less extensive but still real.

Practically, this means a few things. If the parent company loans money to the US subsidiary, the loan should carry an interest rate consistent with what an independent lender would charge. The IRS publishes monthly guidance on acceptable interest rates for intercompany loans, called the Applicable Federal Rate (AFR), available at IRS.gov. Charging zero interest on an intercompany loan, or failing to document the loan at all, creates a tax exposure.

If the parent company provides services to the subsidiary (for example, shared technology, marketing support, or executive oversight), those services should be charged at a rate consistent with the cost of obtaining similar services from an outside provider. A management fee that doesn't reflect the actual cost of services rendered draws IRS scrutiny.

None of this requires a large legal or accounting team to manage. It requires a chart of accounts that tracks intercompany balances separately, documentation of the terms for each type of transaction, and a bookkeeper who knows to flag related-party activity.

How should a US subsidiary's chart of accounts handle intercompany transactions?

The chart of accounts, which is the structured list of categories your business uses to record every financial transaction, needs dedicated accounts for intercompany activity. A standard QuickBooks template does not include these by default.

At minimum, a foreign-owned US subsidiary needs separate accounts for intercompany receivables (what the US entity is owed by related parties), intercompany payables (what the US entity owes to related parties), and intercompany loans (both as an asset, if the US entity lent money, and as a liability, if the US entity borrowed it). If the parent charges management fees, those need a separate expense line. If the subsidiary pays royalties for use of intellectual property, those need their own account.

These accounts serve two purposes. First, they make Form 5472 preparation straightforward: the information the form requires is already organized. Second, they enable parent-company consolidation. Intercompany balances must be eliminated when preparing consolidated financial statements, and they can only be eliminated cleanly if they've been tracked cleanly.

An e-commerce brand that imports its product from a European parent, uses the parent's technology platform, and receives periodic funding from the parent has multiple intercompany transaction types running simultaneously. Setting up the chart of accounts to capture all of them from day one is far less work than reconstructing them from general ledger activity after the fact.

What's the first step a new US subsidiary should take?

Before any money moves between the US entity and its parent, document the terms of every anticipated intercompany relationship. If there will be loans, establish the interest rate and repayment terms in writing. If there will be management fees, define what services they cover and how the amount is determined. If the subsidiary will purchase inventory from the parent, establish a transfer price and the basis for it.

Then build those relationships into the chart of accounts and brief your bookkeeper on the categories. Pilot's bookkeeping service includes controller-level oversight that covers exactly this: ensuring intercompany activity is captured correctly, that Form 5472 preparation is supported by organized records, and that the chart of accounts serves both US compliance requirements and parent-company consolidation.

The cost of setting this up correctly at the start is low. The cost of a $25,000 IRS penalty, or a consolidation reconstruction project, is not.

KEY TAKEAWAY

A foreign-owned US subsidiary has IRS disclosure obligations for every transaction with its parent company, starting from year one regardless of revenue. Setting up the right chart of accounts and documenting intercompany terms before money moves is the difference between a routine annual filing and a penalty that exceeds most startups' monthly burn.
