Transfer Pricing & Permanent Establishment in the EU

A German SaaS founder hires a sales rep in the Netherlands. Three months later, a letter arrives from the Dutch Belastingdienst: the company has created a permanent establishment in the Netherlands and owes Dutch corporate tax on the profits attributable to that Dutch activity. The founder had no idea this was even possible.

This scenario plays out across the EU constantly — and it catches SMEs off guard because transfer pricing and permanent establishment rules are typically discussed in the context of multinationals moving billions through Luxembourg holding structures. The reality is simpler and less comfortable: these rules apply to any company operating across borders, regardless of size. A two-person startup with a contractor in another country can trigger the same obligations that keep Big 4 firms busy.

Here is what permanent establishment actually means, how transfer pricing works at the SME level, and what the EU Inc proposal's HOT system might change about both.

What permanent establishment means

Permanent establishment (PE, in tax shorthand) is the mechanism through which a country claims the right to tax a foreign company's profits. The concept originates in bilateral tax treaties and in the OECD Model Tax Convention, but the practical effect is direct: if your company has sufficient presence in a country where it is not registered, that country can tax a portion of your profits.

The threshold for "sufficient presence" is lower than most founders expect. Under Article 5 of the OECD Model Convention, a PE can be created through:

• A fixed place of business: an office, a branch, a workshop, even a dedicated desk in a co-working space used regularly
• A dependent agent: someone who habitually concludes contracts on the company's behalf in that country, or who plays the principal role leading to contracts being concluded
• A construction or installation project lasting more than twelve months
• Providing services through employees present in that country for more than 183 days in any twelve-month period

The fixed-place-of-business test is the one that catches small companies. A founder who rents a small office in Barcelona for a developer, or who has a sales representative working from home in Vienna five days a week, may have created a PE in Spain or Austria without realising it.

The consequences of an unintended PE are not merely administrative. The host country can assess corporate tax on the profits it considers attributable to the PE, potentially going back several years. Add interest, penalties for non-filing, and the professional fees to resolve the dispute — and a situation that started with one remote hire can cost tens of thousands of euros.

PE risk levels by activity type

Not every cross-border activity creates a PE. The OECD Model Convention explicitly excludes activities that are "preparatory or auxiliary" in character: storing goods, purchasing supplies, collecting information. The difficulty is that the line between auxiliary and core shifts depending on the business model.

A digital agency registered in Estonia with a full-time developer working from a home office in Poland sits squarely in the medium-risk category. Whether that creates a Polish PE depends on specifics: does the developer interact with clients? Do they have authority to commit the company? Is the home office their habitual workplace? Polish tax authorities have been examining these arrangements with increasing scrutiny.

Transfer pricing basics for SMEs

Transfer pricing refers to the prices charged in transactions between related entities, or between a head office and its permanent establishment. The core principle is the arm's length standard: related-party transactions must be priced as if the parties were independent, dealing at market rates.

If your Estonian company pays a management fee to a related entity in Ireland, tax authorities in both countries will ask: is that fee what an independent party would charge for the same service? If the fee is inflated to shift profits from a higher-tax to a lower-tax jurisdiction, both countries have grounds to adjust the taxable income. The adjustments often go in opposite directions, creating double taxation until the dispute is resolved.

The arm's length principle sounds intuitive. In practice, it generates enormous complexity because "what an independent party would charge" is not always obvious. The OECD Transfer Pricing Guidelines, the primary reference framework, run to over 600 pages and describe five main pricing methods, each appropriate for different transaction types.

When transfer pricing applies to small companies

Here is where the misconception lives. Transfer pricing is not a rule that activates at a certain revenue threshold. It applies to any controlled transaction between related parties, regardless of company size. A solo founder with an Estonian OÜ and a Dutch BV in a holding structure has transfer pricing obligations the moment those entities transact with each other.

The practical difference for SMEs is not whether the rules apply — they do — but how aggressively tax authorities enforce documentation requirements. A company doing EUR 80,000 in intercompany transactions attracts less audit attention than one moving EUR 80 million. But "less attention" is not "no obligation." If an auditor does examine your intercompany pricing and finds no documentation, the penalties apply regardless of company size.

The OECD guidelines simplified

The OECD Transfer Pricing Guidelines provide five methods for determining arm's length pricing. For most SME transactions, two matter:

• Comparable Uncontrolled Price (CUP) method. Find what independent parties charge for the same or similar transaction. If three independent consultancies charge EUR 150–180 per hour for similar management services, your intercompany management fee should fall in that range. This is the most direct and preferred method when comparable data exists.

• Cost Plus method. Calculate the actual cost of providing the service, then add a market-standard markup. If your Irish entity provides accounting services to your Estonian entity, the transfer price is the cost of providing those services plus an arm's length margin (typically 5–15% for routine services).

The other three methods (Resale Price, Transactional Net Margin, and Profit Split) apply mainly to complex supply chains, distribution arrangements, and shared intangible assets. Most SMEs will never need them.

Common intercompany transactions and their pricing

Two types of intercompany transactions appear constantly in small cross-border structures, and both require defensible pricing.

IP licensing

A founder creates intellectual property (software, a brand, a methodology) and licenses it from one entity to another within the group. The licensing fee must reflect what an independent licensee would pay for comparable IP. Royalty rates vary enormously by industry and asset type, but the documentation burden is the same: you need a written agreement, a rationale for the rate, and ideally a benchmarking study showing comparable licence deals.

For a small SaaS company licensing its software from a holding entity, royalty rates between 5% and 25% of revenue are common in arm's length benchmarks. The specific rate depends on the value of the IP, the development costs, and who bears the risks. An unsupported 20% royalty flowing to a low-tax jurisdiction is exactly the kind of arrangement that triggers audit attention.

Management fees

Cross-border groups routinely charge management fees for services provided by the parent or head office to subsidiaries: accounting, strategic planning, HR and payroll support, IT infrastructure. The fee must correspond to actual services rendered — a blanket "management fee" with no service agreement and no time records is indefensible.

The practical approach: maintain a service agreement that specifies what services are provided, track the time and resources involved, and price the fee using the cost-plus method with a reasonable markup. For routine management services, markups of 5–10% above actual cost are generally defensible.

Documentation requirements by company size

Transfer pricing documentation is not one-size-fits-all. The OECD's three-tiered approach, and its implementation across EU member states, scales requirements with company size. Most SMEs fall into the lightest tier, but "lightest" still means something.

Germany requires a local file for any company with intercompany transactions above EUR 5 million and expects documentation to be available within 60 days of a request. The Netherlands sets its threshold at EUR 50 million for the full documentation package, but still expects companies below that threshold to substantiate their pricing. Poland introduced a simplified reporting form (TPR) that even small companies must file if their related-party transactions exceed PLN 10 million (roughly EUR 2.3 million).

The honest assessment: most SMEs with modest intercompany transactions — under EUR 1 million annually — face minimal formal documentation requirements. But "minimal" does not mean "none." At a minimum, maintain written intercompany agreements, document the pricing rationale, and keep records that show the price reflects arm's length terms. The cost of doing this properly is a few hours of advisory time. The cost of not doing it, if audited, is substantially higher.

How to stay compliant without a Big 4 firm

Transfer pricing compliance has a reputation for being expensive because the large advisory firms (Deloitte, PwC, EY, KPMG) price their benchmarking studies at EUR 5,000–15,000 per transaction type. For a multinational with hundreds of intercompany transactions across dozens of jurisdictions, that level of analysis is warranted.

For an SME with two entities and three types of intercompany transactions, it is overkill. Here is what actually works at the small-company level:

Start with written agreements. Every intercompany transaction needs a written contract specifying the service or asset, the pricing terms, and the payment schedule. This is not optional — it is the foundation of any transfer pricing defence. A one-page agreement drafted with a local tax advisor costs a fraction of a formal benchmarking study and provides 80% of the protection.

Use publicly available benchmarks. For common services like accounting, IT support, and management consulting, published rate surveys and industry databases provide adequate comparables. The Bureau van Dijk's Orbis database, used by most transfer pricing specialists, has a small-company tier. Several EU tax authorities publish simplified guidance for SMEs that includes acceptable markup ranges.

Document your rationale. A one-page memo explaining why your intercompany pricing is arm's length, citing the method used, the comparables identified, and the resulting price, is worth more in an audit than sophisticated analysis done after the fact. Tax authorities respond well to evidence that the company thought about pricing at the time the transaction was structured, not retroactively.

Get a periodic review. An annual review of your intercompany pricing by a tax advisor who understands transfer pricing costs EUR 1,000–3,000 for a simple structure. That is the actual cost of compliance for most SMEs, not the EUR 50,000 engagement that Big 4 proposals suggest.

How EU Inc's HOT system might reduce PE risk

The Head Office Tax system (HOT) is designed to address precisely the PE problem described above. Under HOT, a qualifying EU Inc files and pays corporate tax only in the country where its head office is located. The host country's claim to tax profits attributable to a PE is superseded for qualifying companies.

For the German SaaS founder with the Dutch sales rep: under HOT, the entire company files in Germany. The Netherlands cannot assert a PE claim. No Dutch corporate tax filing. No profit attribution exercise. No dispute between two tax authorities.

This is not a theoretical benefit. Multi-country PE management is one of the most expensive compliance burdens for cross-border SMEs, easily costing EUR 10,000–25,000 per year in advisory fees across two or three jurisdictions. HOT eliminates that cost for qualifying companies, and the qualification criteria are designed for SMEs with revenue under EUR 10 million.

The interaction between HOT and transfer pricing is less clear. If an EU Inc has a subsidiary (as opposed to just employees or agents) in another country, the subsidiary remains a separate legal entity with its own tax obligations. Transfer pricing still applies to transactions between the EU Inc and its subsidiary. HOT eliminates the PE layer but does not eliminate the separate-entity layer.

Practical steps for founders operating across borders

If you already have operations in more than one EU country, or are planning to, here is the sequence that keeps you compliant without overcomplicating things:

Map your cross-border touchpoints. List every person (employee, contractor, agent) working for your company outside the country of registration, every office or co-working space used regularly, and every intercompany transaction. This is your PE and transfer pricing exposure map.

Assess PE risk for each touchpoint. Apply the tests above: is the person closing deals or signing contracts? Is the office used regularly and exclusively? Is the activity core to the business or auxiliary? If any touchpoint falls in the medium or high-risk category, get a specific opinion from a tax advisor in that country.

Document intercompany transactions from day one. Written agreements, pricing rationale, and basic benchmarking. Do this when you structure the arrangement — not when the audit letter arrives.

Review annually. Business circumstances change. A contractor who started as auxiliary might now be managing a key client relationship. An office used occasionally might have become a permanent base. Annual review catches drift before it becomes a problem.

Watch the EU Inc timeline. If HOT passes in its proposed form, it will substantially reduce PE risk for qualifying SMEs. But the timeline remains uncertain. For the current state of the proposal, see our analysis of EU Inc's legislative prospects. Do not defer compliance today based on legislation that has not been enacted.

For founders comparing jurisdictions now, our comparison of Estonia, Ireland, and the Netherlands covers the practical differences in tax treatment, formation cost, and compliance burden across three popular choices.

The bottom line

Permanent establishment and transfer pricing are not problems reserved for multinationals. Any company with employees, contractors, or related entities in more than one country faces these rules. The penalties for getting them wrong are disproportionate to the underlying tax at stake.

The good news: compliance at the SME level is manageable. Written agreements, defensible pricing, and basic documentation handle the vast majority of cases. You do not need a Big 4 engagement. You need a local tax advisor who understands cross-border structures and a commitment to documenting your rationale as you go.

EU Inc's HOT system, if enacted, will remove the PE layer entirely for qualifying companies. That is a real reduction in both risk and cost for founders operating across borders. Transfer pricing obligations will persist for separate entities within a group, but the most common trigger for unexpected tax bills — an unintended PE created by a remote employee or contractor — goes away under HOT.

Until HOT is law, the rules are the rules. Document, price at arm's length, and review annually. The cost of doing this properly is a rounding error compared to the cost of an adverse audit finding.
