Accounting for intercompany loans works like accounting for any other debt, with three added layers: the interest rate has to satisfy the arm’s length standard under Section 482, both sides of the transaction must be eliminated when the group consolidates, and the documentation has to be strong enough that the IRS treats the advance as debt rather than a disguised equity contribution. Get those three right and the rest is bookkeeping.
Booking the Loan on Both Sides
When cash moves, both entities record the loan at the principal amount. The lender debits an intercompany receivable and credits cash. The borrower debits cash and credits an intercompany payable. For a $500,000 advance, the lender’s entry is a $500,000 debit to “Intercompany Receivable – [Borrower Name]” and a $500,000 credit to “Cash”; the borrower posts the mirror image.
Classification depends on the maturity. If the principal comes due within twelve months of the balance sheet date, it sits in current assets and current liabilities. If it stretches beyond a year, it goes to the non-current section, with the portion due in the next twelve months reclassified to current each reporting period. That reclassification directly affects working capital ratios that lenders, investors, and credit rating agencies rely on.
Give each intercompany relationship its own general ledger accounts. A parent lending to three subsidiaries should carry three separate receivable accounts rather than one lumped balance. That granularity makes month-end reconciliation manageable and prevents problems during consolidation, when every intercompany balance has to net to zero.
Setting the Interest Rate
Section 482 of the Internal Revenue Code requires that the interest rate on an intercompany loan match what unrelated parties would agree to under similar circumstances: same loan size, same credit risk, same maturity, same currency.1eCFR. 26 CFR 1.482-2 – Determination of Taxable Income in Specific Situations Charge too little and the IRS imputes income to the lender. Charge too much and the borrower’s deduction gets trimmed.
A Treasury safe harbor simplifies the analysis for most loans. If the rate falls between 100% and 130% of the Applicable Federal Rate, the IRS will generally accept it without further scrutiny.2Internal Revenue Service. Development of IRC 482 Cases The IRS publishes updated AFRs monthly in three tiers: short-term for loans of three years or less, mid-term for over three years up to nine years, and long-term for over nine years.3Internal Revenue Service. Applicable Federal Rates As of late 2025, the short-term AFR was roughly 3.8%, the mid-term around 3.9%, and the long-term about 4.7% on an annual compounding basis. Those figures shift monthly, so check the current revenue ruling before finalizing a rate.
Rates outside the safe harbor need a benchmark study comparing the intercompany terms to loans between unrelated parties. The IRS looks at five comparability factors: functions each party performs, contractual terms, risks assumed, economic conditions, and the nature of the property or services involved.2Internal Revenue Service. Development of IRC 482 Cases
Recording Interest Each Period
Interest accrues on the accrual method regardless of when cash actually moves. Each month the lender debits “Intercompany Interest Receivable” and credits “Interest Income.” The borrower debits “Interest Expense” and credits “Intercompany Interest Payable.”
On a $10,000 balance at 6% annual interest, the monthly entry is $50 ($10,000 × 0.06 ÷ 12). When cash actually changes hands, the receivable and payable clear, so the interest never flows through income twice.
Below-Market Loans
Section 7872 applies when a loan carries no interest or a rate below the AFR. The statute treats the foregone interest as if the lender gave it to the borrower and the borrower immediately paid it back as interest.4Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates Both sides recognize interest on their tax returns even though no interest actually moved.
For a term loan, Section 7872 compares the face amount to the present value of all required payments, discounted at the AFR. The gap is a transfer from lender to borrower on the loan date.5Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The borrower debits cash for the amount received, credits the intercompany payable for the face value, and debits a “Discount on Note Payable” for the difference. That discount amortizes into interest expense over the loan’s life using the effective interest method. The lender records a corresponding discount that amortizes into interest income on the same schedule. The net result is that both entities report interest as if the loan had been priced at the AFR from day one.
Keeping the Loan From Being Recharacterized as Equity
The most consequential risk in intercompany lending is that the IRS reclassifies the entire loan as an equity contribution. Every interest payment the borrower deducted then gets recharacterized as a non-deductible dividend distribution. The borrower loses the interest deduction under Section 163(a), and the lender’s interest income becomes dividend income with different tax treatment.6Office of the Law Revision Counsel. 26 US Code 163 – Interest
Section 385 authorizes Treasury to issue regulations distinguishing debt from equity, and lists several factors that matter:7Office of the Law Revision Counsel. 26 US Code 385 – Treatment of Certain Interests in Corporations as Stock or Indebtedness
- Whether there is an unconditional written promise to repay a fixed amount on a set date with a stated interest rate
- Whether the loan is junior to all other creditors, which makes it look more like equity
- Whether the borrower is so thinly capitalized that repayment depends on future profits rather than existing resources
- Whether the instrument can convert to stock
- Whether the loans mirror shareholding percentages, suggesting the “loan” is really an additional equity investment
Courts also look at whether scheduled payments were actually made on time, whether the borrower had a realistic ability to repay, whether the lender enforced its rights when payments were missed, and how both parties treated the transaction on their books. If you want the IRS to treat it as debt, make it look and behave like debt. That means a signed promissory note, a fixed maturity, regular scheduled payments, and an interest rate within the safe harbor range.
The same documentation earns another payoff later. Section 166 allows a bad debt deduction when an intercompany loan becomes wholly or partially worthless, and corporations get to deduct it as an ordinary loss.8Office of the Law Revision Counsel. 26 US Code 166 – Bad Debts But the deduction only works if the IRS accepts that the advance was genuine debt in the first place. On the GAAP side, intercompany loans between entities under common control are excluded from the CECL model in ASC 326-20; impairment gets assessed under other applicable guidance, or under the general contingency framework in ASC 450-20, with a loss recognized when it becomes probable that some or all of the loan will not be collected.
Deduction Limits and Timing Traps
Even when the rate passes the arm’s length test, the borrower’s interest deduction may still be capped. Section 163(j) limits business interest deductions to 30% of adjusted taxable income, and intercompany interest counts toward the same ceiling as third-party debt. For tax years beginning after December 31, 2025, adjusted taxable income adds back depreciation, amortization, and depletion, making the base closer to EBITDA than the narrower EBIT measure that applied during 2022 through 2025.9Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Disallowed interest carries forward, but it creates a temporary difference the tax provision has to track.
Section 267(a)(2) sets a separate trap. When a borrower and lender are related, the borrower cannot deduct accrued interest until the lender actually includes it in income.10Office of the Law Revision Counsel. 26 US Code 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers If the lender is on the cash method and the borrower is on accrual, the borrower’s books show interest expense every month but the tax deduction has to wait until the cash is actually paid. The GAAP accounting looks fine because accrual entries post normally on both sides. The problem surfaces only on the tax return, and interest that accrues across year-end without a cash payment needs a timing adjustment to defer the deduction.
Cross-Border Interest Payments
Interest paid by a U.S. entity to a foreign parent or affiliate generally triggers a 30% federal withholding tax unless a treaty or statutory exemption reduces the rate.11Internal Revenue Service. Instructions for Form 1042-S The U.S. borrower is the withholding agent, meaning it deducts the tax from the interest payment and remits it to the IRS. Many bilateral treaties reduce the withholding rate to 0% or a lower percentage, but claiming the reduced rate requires the foreign lender to provide valid documentation (typically Form W-8BEN-E) before the payment is made.
Each payment subject to withholding gets reported on Form 1042-S, filed annually with the IRS and furnished to the foreign recipient. The withholding agent also files Form 1042 as the annual summary return. Fail to withhold when required and the U.S. entity becomes personally liable for the tax that should have been collected.
Required Information Reporting
A 25%-or-more foreign-owned U.S. corporation must file Form 5472 for each foreign related party with which it had reportable transactions during the year, including intercompany loans and interest payments. The form attaches to the corporation’s income tax return and follows the same filing deadline. For transactions totaling $50,000 or less with a foreign related party, the amount can be reported as “$50,000 or less” rather than the exact figure.12Internal Revenue Service. Instructions for Form 5472
The penalty for failing to file Form 5472, or filing a substantially incomplete one, is $25,000 per form per year. If the failure continues more than 90 days after IRS notification, an additional $25,000 penalty accrues for each 30-day period the failure persists.12Internal Revenue Service. Instructions for Form 5472 Each entity in a consolidated group is treated as a separate reporting corporation, so penalties stack quickly across a multinational structure.
U.S. shareholders of certain foreign corporations (Category 4 filers) report intercompany loan activity on Schedule M of Form 5471. That includes the largest outstanding balance during the year of gross amounts borrowed from related parties on Line 32 and gross amounts loaned to related parties on Line 34.13Internal Revenue Service. Instructions for Form 5471 Report the peak outstanding balance, not the year-end balance, average balance, or net cash flow.
Documentation to Keep on File
A signed loan agreement is the single most important document supporting debt treatment. It should specify the principal amount, interest rate, maturity date, repayment schedule, and any collateral. Without a formal agreement, the IRS has a much easier path to recharacterizing the transaction.
For loans outside the AFR safe harbor, the rate needs a benchmark study identifying comparable third-party transactions and demonstrating that the intercompany rate falls within a defensible range. The study should address the five comparability factors and explain why the selected comparables are appropriate. The IRS expects transfer pricing documentation to exist when the tax return is filed, not to be produced after the fact during an audit.14Internal Revenue Service. Transfer Pricing Documentation Best Practices Frequently Asked Questions (FAQs) Inadequate documentation exposes the taxpayer to transfer pricing adjustments and accuracy-related penalties of 20% of the underpayment for a substantial valuation misstatement, or 40% for a gross valuation misstatement.15Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Ongoing records matter as much as the initial paperwork. Document each interest accrual, track actual cash payments against the schedule, record any amendments, and keep board minutes or resolutions authorizing the transaction. If payments are missed or deferred, document why and how the lender responded. Creditors in arm’s length relationships don’t silently ignore defaults, and neither should an intercompany lender that wants to preserve debt treatment.
Eliminating Balances in Consolidation
Every intercompany balance and transaction has to be eliminated in the consolidated financials. The goal is to present the group as a single economic entity, with only third-party activity showing on the statements.
The intercompany receivable on the lender’s books and the intercompany payable on the borrower’s books should be mirror images. The elimination entry debits the payable and credits the receivable. If the lender shows a $1 million receivable and the borrower shows a $1 million payable, both zero out. Any mismatch, even $100, needs investigation before posting. Common culprits are timing differences on cash transfers that cross a period-end, unrecorded interest accruals on one side, and foreign currency translation differences.
Interest income on the lender’s books and interest expense on the borrower’s books also get eliminated. If both entities recorded $60,000 during the period, the entry debits “Intercompany Interest Income” for $60,000 and credits “Intercompany Interest Expense” for the same amount. Accrued interest receivable and payable require a separate elimination: debit the intercompany interest payable, credit the intercompany interest receivable. Small differences in accrued interest have a way of compounding over multiple periods and becoming difficult to untangle later, so reconcile and eliminate every intercompany account (principal, interest income and expense, and accrued interest) in a single coordinated close each period.
