What it means
When modern businesses grow, they often operate through multiple distinct legal entities, such as subsidiaries, regional branches, or holding companies. Sometimes, one of these entities has excess cash sitting in its bank account, while another sister company urgently needs funds to purchase inventory, upgrade equipment, or manage a temporary cash flow dip.
Rather than approaching an external bank, paying steep origination fees, and going through lengthy credit checks, the cash-rich company can simply lend money to the related entity. This keeps borrowing costs inside the broader corporate family and allows the group to deploy its capital efficiently without relying on outside lenders.
From an accounting perspective, these loans must be carefully managed. When the parent company prepares consolidated financial statements combining all its subsidiaries, intercompany loans are treated as internal transactions and are completely eliminated.
This prevents the business from accidentally inflating its total assets and liabilities by counting money it owes to itself. However, treating these arrangements casually can create major problems.
Tax authorities around the world require that intercompany loans use market-rate interest, often called arm-length pricing. If a parent company lends money to a subsidiary at zero interest to artificially shift profits or hide losses, tax regulators can step in and penalise the business.
Therefore, every intercompany loan needs a formal promissory note, a clear repayment schedule, and a realistic interest rate, just like a loan with an external bank. Imagine a family where one sibling has saved up pocket money and lends some to another sibling to buy a new bicycle.
It stays within the family, but they still write down the rules on a piece of paper to make sure it gets paid back fairly.
In practice
Real-world examples
Example 1
ParentCo lends $50,000 to its newly formed UK retail subsidiary at a 5% interest rate to help fund its initial store fit-out and purchase opening stock, bypassing traditional bank fees. The loan is documented with a short agreement and repayment dates. The subsidiary pays $2,500 interest per year.
Example 2
A software consulting firm with excess cash reserves lends $25,000 to its sister marketing agency for three months to cover a temporary cash flow gap caused by delayed client payments. Both companies record the loan, and the agency repays it with interest when its clients pay. The lender earns a return on cash that would otherwise sit idle.
Example 3
A manufacturing group provides a $100,000 equipment loan to its logistics subsidiary so the smaller business can buy a delivery van without needing a commercial vehicle loan. The subsidiary repays in monthly instalments. The group's accountants confirm the interest rate is in line with what an external lender would offer.

Formula
Calculation
Interest Payment = Principal Loan Amount x Annual Interest Rate x (Months Outstanding / 12)
Example: a $50,000 loan at 6% interest for 6 months. Calculation: $50,000 x 0.06 x (6 / 12) = $1,500 interest.
Arm's Length Check: compare the rate charged with what an independent bank would charge. If a bank would lend the same $50,000 at 8% for the same 6 months, interest at that rate is $50,000 x 0.08 x (6 / 12) = $2,000. Charging only $1,500 leaves $500 of interest income that tax authorities may say should have been reported by the lender, so the rate or the documentation may need to be adjusted.Case study
Seen in the real world
This is a fictional, illustrative scenario. BrightRetail Ltd operated two distinct businesses through separate limited companies: an online clothing shop and a high street boutique. The online shop experienced rapid growth and accumulated $80,000 in surplus cash. Meanwhile, the high street boutique needed to upgrade its point-of-sale system urgently, but high street banks quoted steep interest rates and demanded lengthy paperwork. Instead of borrowing externally, the directors set up an intercompany loan.
The online shop lent $30,000 to the boutique. They drafted a formal loan agreement specifying a 4% annual interest rate and a 12-month repayment term, so the boutique owed $30,000 x 0.04 = $1,200 of interest over the year. This allowed the boutique to upgrade its tills quickly, saved the group hundreds of dollars in external bank fees, and gave the surplus cash a small return. At year-end, when the group accountant prepared consolidated financial accounts, the $30,000 loan asset in one company and the $30,000 loan liability in the other were eliminated, along with the matching $1,200 of interest income and expense. Each company's own accounts and tax return still showed the interest, which kept the arrangement properly documented for tax purposes.
Watch out
Common mistakes
- Failing to document the loan with a formal written agreement, which can cause severe issues during tax audits.
- Charging zero interest or a below-market rate, which can trigger penalties from tax authorities for unfair profit shifting.
- Forgetting to eliminate these internal loans when preparing consolidated group financial statements.
Questions
People also ask
Do intercompany loans show up on consolidated financial statements?
No. When a parent company combines the financial reports of all its subsidiaries, intercompany loans and their associated interest are eliminated so they do not distort the true financial position of the group.
Why do we need a formal agreement for a loan between our own companies?
Tax authorities require proof that transactions between related companies reflect fair market conditions. A formal agreement protects the business during audits and proves the arrangement is a genuine loan.
What happens if the borrowing company cannot repay the intercompany loan?
The lender may need to write off the loan as bad debt. Depending on local tax laws, this write-off can have complex tax consequences for both entities, requiring professional accounting advice.
