Cross-border business financing adds a second tax system to every loan decision, whether the lender is a foreign bank or the parent company itself. Finance teams tend to compare offers by margin and fees. Across a border, the after-tax cost also depends on which group company borrows and where the lender is resident.
Why financing structure is important in international business
If a parent funds a subsidiary with debt rather than equity, it changes which country taxes the return. It also changes how much of the cost the subsidiary may deduct. The subsidiary usually deducts interest on a loan. It pays dividends out of profit after tax.
| Funding from the parent | Payment back to the parent | Deduction for the subsidiary | Tax as the payment leaves |
| Shareholder loan | Interest payments | Allowed within the interest caps in force | Interest withholding tax at treaty or domestic rates. The EU Interest and Royalties Directive exempts payments between associated companies |
| Share capital | Dividends | No deduction | Often taxed at source. A qualifying EU parent receives them free of withholding tax under the Parent-Subsidiary Directive |
| Hybrid instrument | A return the payer deducts and the parent receives tax-free | Denied in the EU under the anti-hybrid rules | Depends on how the source country classifies it |
For years, intra-group interest was the simplest way to move profit into a low-tax country. The OECD’s project against base erosion and profit shifting (BEPS) dealt with it in 2015, in Action 4. The proposal there was a fixed ratio rule. Any country that adopts it caps net interest deductions at 10%-30% of EBITDA, earnings before interest, tax, depreciation and amortization.
How residence changes the cost of borrowing
A lender prices its loan on the net interest it receives. If the borrower’s country withholds tax, a gross-up clause makes the borrower pay that tax on top of the interest. In the UK, the rate is 20% on yearly interest to a lender abroad. A treaty can cut it to nil for a qualifying lender.
| UK borrower, £10 million at 6% a year | Lender with treaty relief | Lender without relief, payment grossed up |
| Interest the lender keeps | £600,000 | £600,000 |
| UK tax withheld | £0 | £150,000 |
| Yearly cost to the borrower | £600,000 | £750,000 |
Treaty relief depends on where each party is tax resident, whatever the register says. If the directors of a foreign subsidiary take its main decisions in the UK, it becomes UK resident. The central management and control test decides that. Its country of registration may still claim it as a resident too.
Under many treaties, HM Revenue & Customs (HMRC) and the foreign tax authority try to agree on one treaty residence. If they can’t, HMRC treats the company as dual resident. A subsidiary that holds its board meetings in its own country defends its corporate residence more easily.
Commercial loans and credit facilities for cross-border operations
Commercial loans for international expansion range from a single term loan to syndicated loans from several banks. Which facility a group needs depends on the size of the expansion and on which subsidiary will service the debt.
| Type of facility | How it operates | Typical use abroad |
| Term loan | A fixed amount repaid in installments or at maturity | An acquisition or new fixed assets |
| Revolving credit facility | Repaid drawings can be drawn again up to a limit. A fee applies to the unused part | Working capital for subsidiaries in several countries |
| Syndicated loan | Several banks lend under one agreement. An agent bank collects and distributes payments | Amounts above one bank’s limit for a single borrower |
| Local loan with parent support | A bank in the subsidiary’s country lends against a parent guarantee or a standby letter of credit from the parent’s bank | A new subsidiary without its own trading record |
In cross-border lending, a group with subsidiaries in several countries can ask for a multicurrency option. A subsidiary that sells in euros then draws euros and repays from its own sales. The bank prices international business loans at a margin over the reference rate of each currency.
In a growth funding or M&A deal, the bank lends against the cash flow of the combined business. It takes security over the target’s assets. Its loan rarely funds the whole price. The seller may defer a share through a vendor loan or an earn-out, a later payment that depends on the target’s results. Equity from the buyer funds the rest.
Trade finance and export credit
An exporter secures payment on an international sale through trade finance, a set of bank instruments. The buyer still receives credit terms.
| Trade instrument | How it operates | Main protection |
| Documentary letter of credit | The buyer’s bank undertakes to pay once the exporter presents documents that match the credit’s terms | The exporter relies on a bank’s promise to pay |
| Documentary collection | Banks release shipping documents against payment or the buyer’s signed promise to pay later. No bank guarantees payment | The buyer can’t claim the goods before paying or signing |
| Standby letter of credit or demand guarantee | A bank pays on demand if the buyer or contractor defaults | Default on payment or performance |
| Export credit insurance | An insurer pays the exporter if a foreign buyer doesn’t pay for commercial or political reasons | Losses on sales on open account |
| Forfaiting | The exporter sells medium- or long-term receivables at a discount, without recourse | Immediate cash for a deferred-payment sale |
Under a letter of credit, banks deal only in documents. The International Chamber of Commerce’s UCP 600 rules allow a bank up to five banking days after presentation to examine the documents. A shipment after the latest date in the credit or a missing certificate is a discrepancy. The bank may refuse payment on that ground.
A tax authority can obtain the invoices and transport documents behind a credit from the bank that holds them. Treaties on the OECD Model or the US Model don’t let a country refuse such a request only because a bank keeps the records. Through exchange of information, the authority can then compare intra-group invoice prices with the group’s transfer pricing policy for dealings between its own companies.
Export credit agencies
Most countries have an export credit agency (ECA). In the United States, the Export-Import Bank guarantees 90% of a bank’s working capital loan where the exports carry at least 10% US content. In the UK, Export Finance backs trade loans and letter of credit lines of up to ~£25 million through its General Export Facility.
ECA support for credit of two years or more follows the OECD Arrangement on Officially Supported Export Credits. The 2026 text sets a minimum down payment of 15% of the contract value. In most sectors, repayment of the balance can’t exceed 15 years. An exporter that plans a deferred-payment sale with ECA support builds these terms into its offer.
Private equity and alternative funding sources
Banks lend against assets and cash flow. When those can’t support the sum a company needs, it raises the balance from equity investors or from lenders outside the banking system. A private equity fund buys shares and takes a minority stake or control of the company.
Because most private equity funds are limited partnerships with a fixed life, the fund agrees an exit plan from the outset. Usually it sells to another buyer or lists the company.
Private credit began as finance for companies too large or risky for banks and too small for public markets. It has grown quickly since. The International Monetary Fund (IMF) estimated the market at ~$2.1 trillion in assets and committed capital in 2023. Instruments in this market differ mainly in rank and cost.
| Funding instrument | How it operates | Cost or term |
| Venture debt | A loan to a venture-backed company with a warrant, the lender’s right to buy shares later at a fixed price | Typically 3-4 years, with monthly interest and repayments |
| Mezzanine finance | Debt repaid after senior lenders and before shareholders, often with warrants | A typical cost of 10%-30% |
| Unitranche loan | Senior and junior debt combined in one facility from a single lender | One blended rate and one set of covenants |
Real estate financing in multi-jurisdictional structures
An international investor usually finances commercial property through a loan to the company that owns it. The owner is often a special purpose vehicle (SPV) with a single asset. The lender takes a mortgage over the property and an assignment of the rents. Recourse normally ends at the SPV, so the lender can’t claim the parent’s other assets.
At the end of 2025, the average senior loan on UK commercial property, the first-ranking debt, was ~54%-59% of value across sectors. Four of the twelve largest lenders that year were debt funds. A buyer can approach them as well as UK and international banks.
Local tax rules also change the cost of the loan and of the exit.
| Country of the property | What happens | Tax rule |
| United States | A foreign owner sells US property | The buyer withholds 15% of the amount realized under the Foreign Investment in Real Property Tax Act |
| United States | A foreign shareholder lends to the US property company | No portfolio interest exemption for a lender holding 10% or more, so withholding applies at the statutory or treaty rate |
| Germany | Shares in a property company change hands | Real estate transfer tax applies once 90% of the shares change owner within ten years |
| United Kingdom | An overseas company lets UK property | Corporation tax on rental profits since April 2020, with the same interest restriction as UK groups |
UK rules for overseas owners
An overseas company can’t grant a lender a charge over UK land until it registers as an overseas entity with Companies House. A group that also holds residential units follows the separate rules on how to structure home ownership in the UK. A corporate buyer generally pays stamp duty land tax at a flat 17% on a home above £500,000.
Since 2015, a non-resident seller has paid UK capital gains tax on homes. Commercial property followed in 2019, as the article on UK real estate taxation explains.
Tax and regulatory considerations when choosing a financing option
Tax authorities examine cross-border business financing between group companies most closely. One group sets the terms for lender and borrower alike. A loan from an outside bank receives fewer checks.
Pricing loans between group companies
Since February 2020, Chapter X of the OECD Transfer Pricing Guidelines has set the rules for transfer pricing on loans. A tax authority first asks whether an independent lender would have advanced the amount at all. If not, it may treat part of the loan as equity. The subsidiary then loses the interest deduction on that part.
The group sets the rate on the borrower’s own credit standing and the implicit support it can expect as a group member. A parent may charge a guarantee fee only for the benefit beyond that support. A credit analysis of the borrowing subsidiary at the loan date is the usual evidence.
Interest caps and thin capitalization
A company whose debt is high compared with its earnings or equity deducts only part of its interest under thin capitalization rules.
| Where the rule applies | Main limit | Exemption or extra rule |
| EU minimum under the Anti-Tax Avoidance Directive | 30% of tax EBITDA | Member states may exempt net interest up to €3 million and standalone companies |
| United States, under section 163(j) | 30% of adjusted taxable income. Since 2025 that income is counted before depreciation and amortization | Average gross receipts of $32 million or less for 2026 |
| United Kingdom, corporate interest restriction | 30% of tax EBITDA, or a group ratio | Groups whose net interest expense is £2 million a year or less |
| France | 30% of tax EBITDA or €3 million, whichever is higher | A lower cap of 10% of EBITDA or €1 million where related-party debt exceeds 1.5 times equity |
France revises these rules in its annual finance acts. The current regime came with the act for 2019.
Withholding tax and treaty access
A foreign corporation pays a 30% US tax on US-source interest. The portfolio interest exemption or a treaty can reduce it to zero. Within the EU, an associated company receives interest free of withholding tax from a 25% direct holding.
Under the OECD’s minimum standard on treaty shopping, a treaty denies benefits when obtaining them was one of the principal purposes of the arrangement. A borrower that pays interest to an affiliate in a jurisdiction the EU lists as non-cooperative may owe extra tax as well. The Netherlands, for example, withholds 25.8% on such interest in 2026.
Most US treaties have limitation-on-benefits clauses. A listed lender qualifies if its shares trade regularly on a recognized exchange at home. An unlisted lender can qualify if qualifying residents own 50% or more of it. Its deductible payments to non-qualifying persons must remain under half its gross income. A finance company with a third-country parent usually fails these tests.
Approvals and reporting
Under DAC6, the EU’s mandatory disclosure regime, a group’s adviser may have to report an intra-group financing arrangement. The deadline is 30 days. One trigger is a deductible payment to a group company resident where corporate tax is zero or almost zero. A tax advantage must also be among its main benefits.
A foreign stake in a US business may need clearance from the Committee on Foreign Investment in the United States. Where a foreign government acquires a substantial interest in certain US businesses, the parties must file a declaration in advance. A deal in critical technologies carries the same duty. A review and any later investigation can take 45 days each.
FAQ
Do loan fees count toward the EU interest cap?
Yes. The EU’s anti-tax avoidance directive treats guarantee fees and arrangement fees as borrowing costs. Notional interest under hedges of the company’s own borrowing counts as well.
Why would an exporter ask for a confirmed letter of credit?
Confirmation protects the exporter against the issuing bank’s default and against political risk in the buyer’s country. The confirming bank, often in the exporter’s own country, adds its own undertaking to pay to that of the buyer’s bank.
Can a US subsidiary deduct interest it owes its foreign parent before paying it?
No. Section 267(a)(3) defers the deduction for amounts due to a related foreign person until the year of payment. A subsidiary that settles a shareholder loan’s interest only at maturity can deduct none of it earlier.
Can a bank outside the EU lend directly to a company in the EU?
Only through an authorized local branch from January 11, 2027. The revised Capital Requirements Directive will require a non-EU bank to hold such a branch in each member state where it lends. A client that approaches the bank on its own exclusive initiative is exempt. Loans within one group are exempt too. Contracts from before July 11, 2026 keep their current terms.
