Transfer Pricing Basics Every Entrepreneur Should Know

Most founders meet transfer pricing by accident. You set up a holding company in one country, an operating company in another, perhaps a personal-services or IP company somewhere efficient, and then you move money between them: a management fee here, a licence fee there, a loan to fund the next phase. Each of those flows is a transfer pricing transaction, whether you realised it or not.

The good news is that transfer pricing for a smaller international group is governed by the same core idea as for the largest multinationals, and that idea is intuitive. The rules exist to stop businesses shifting profit artificially between their own entities. If your pricing reflects commercial reality, you are most of the way to compliance. The danger lies in not knowing the rules apply at all.

This guide explains the basics in plain terms: when transfer pricing bites, what the standard actually requires, and the practical mistakes that catch growing businesses.

When the rules apply to you

Transfer pricing rules apply to transactions between associated enterprises, broadly, entities under common ownership or control. The moment you own two companies and they transact with each other across a border, the prices on those transactions are in scope. It does not matter that you own both sides. In fact, that is precisely why the rules exist.

A common misconception is that transfer pricing is only for large corporations. The headline obligations, such as country-by-country reporting and elaborate master files, are indeed reserved for big groups above high revenue thresholds. But the underlying arm's length requirement applies to almost everyone, and many countries impose documentation duties on businesses far smaller than people assume. Some jurisdictions offer simplified regimes or safe harbours for small and medium enterprises; others do not.

If your structure includes a management company charging fees to a trading subsidiary, an IP company licensing a brand back to the business, or a parent lending to a subsidiary, you are doing transfer pricing. The question is only whether you are doing it defensibly.

The arm's length principle, simply put

The standard you must meet is the arm's length principle: price your intercompany transactions as if the two entities were independent businesses negotiating at arm's length. Ask yourself what an unrelated third party would have charged, or paid, for the same thing in the same circumstances.

If your UK operating company pays your low-tax holding company a GBP 200,000 annual "management fee", the tax authority will want to know what that fee buys. What services are actually performed? By whom? Would an independent company have paid that amount for them? If the answer is that little is genuinely provided, the fee is exposed, and an adjustment, plus interest and penalties, can follow.

The same logic governs intercompany loans, where the interest rate must be commercially realistic, and intercompany licences, where the royalty must reflect the value of what is licensed and which entity actually built and controls it. Legal ownership alone does not justify a return; substance does.

Keep documentation proportionate but real

You do not need a hundred-page study to run a sensible small-group structure, but you do need a clear, contemporaneous record of why your pricing is what it is. At minimum, hold proper written intercompany agreements for every recurring flow, describe the services or assets involved, and keep a short note explaining how the price was set and why it is reasonable.

For service fees, that might mean a cost-based calculation with a modest mark-up. For a loan, it means evidence of a comparable commercial interest rate. For a royalty, it means a reasoned link between the rate and the value of the intangible. The aim is to be able to answer, calmly and on paper, the first question any examiner asks: how did you arrive at this number?

Documentation prepared at the time carries far more weight than something reconstructed two years later under audit pressure. In many systems it also protects you from penalties even where the authority disagrees with your figure.

The mistakes that catch growing businesses

The first and most common error is paperwork that does not match conduct. Founders sign an agreement saying the offshore company owns the IP and bears the risk, while in reality the founder, sitting in a high-tax country, makes every decision and does all the work. Tax authorities follow the people and the functions, not the letterhead.

The second is round-number fees with no basis, the GBP 10,000-a-month management charge that nobody can explain. The third is ignoring the loan question: funding a subsidiary by intercompany loan with no interest, no agreement, and no thought to thin-capitalisation rules. The fourth is assuming that because a structure was recommended once, it remains correct as the business grows and the genuine centre of activity shifts.

There is also a broader trap. Aggressive profit-shifting that might once have gone unnoticed now sits within a global system designed specifically to detect it. Information is shared between countries automatically. A structure that depends on profit ending up somewhere no real work is done is, in 2026, a liability rather than an advantage.

Building it right from the start

The encouraging news is that a clean structure is not expensive to maintain. If profit broadly follows where the value is genuinely created, if your intercompany pricing is reasonable and documented, and if your agreements describe what actually happens, you have little to fear from a transfer pricing review.

The right time to get this in order is when you set the structure up, or now, if you did not. Retro-fitting compliance onto years of unexplained intercompany flows is harder and more costly than starting clean.

How HPT helps

We help founders and growing international groups put transfer pricing on a sound footing without over-engineering it: sensible intercompany pricing policies, proportionate documentation, properly drafted agreements, and a structure where substance and paperwork tell the same story. As you scale, we keep the policy aligned with where your people and decisions actually sit.

If you have entities transacting across borders and you are not sure your pricing would survive a question, we would be glad to take a look.
