Principal Purpose Test

Most founders do not encounter the Principal Purpose Test when they go global. They encounter it much later, often after the structure has already proven itself “successful”. The company has scaled, money is moving across borders, investors are comfortable, and the setup has survived years of routine compliance.

That is when the surprise hits. Treaty benefits are denied even though the structure is legally sound, filings are clean, and advisors had earlier signed off. From a founder’s perspective, this feels illogical. If nothing is technically wrong, how can the outcome still break?

The answer is uncomfortable. PPT is not interested in whether the structure worked. It is interested in why it exists now.

The Rule That Overrides Technical Compliance

The Principal Purpose Test allows tax authorities to deny treaty benefits if one of the principal purposes of an arrangement is obtaining that benefit, even when all formal treaty conditions are met. In other words, meeting the letter of the treaty is not enough if the broader arrangement is seen as tax-driven in substance.

For founders, that single idea is the entire point. PPT does not invalidate structures, unwind entities, or challenge legality. It simply allows authorities to ignore the expected tax outcome if the commercial story does not hold up. Everything else that follows is about how this judgement is applied in real businesses, often years after the structure was put in place.

Why Compliance Stops Protecting You After the Business Works

Founders instinctively treat compliance as a finish line. Once a structure clears legal and tax review, it is mentally categorised as solved. PPT operates on a different timeline.

Authorities do not assess whether the structure was compliant when it was set up. They assess whether it still makes commercial sense given how the business actually functions today. This distinction is where many technically valid structures quietly fail.

A common founder experience illustrates this:

●      A group set up a global holding structure early, advised that it was clean and widely accepted.

●      Years later, when profits scaled, that same structure was reviewed as a living arrangement, not as a legal artefact.

●      The question shifted from “Is this allowed?” to “What role does this entity truly play in value creation?”

Compliance protects form. PPT interrogates purpose.

PPT is Not a Setup Problem. It is a Scale Problem.

One of the most consistent misunderstandings founders have is when PPT risk arises. It is almost never triggered at incorporation or during early-stage operations. It emerges when outcomes become meaningful.

Treaty benefits only attract scrutiny once they materially affect tax collections:

●      Dividend repatriation

●      Capital gains exemptions

●      Large intercompany flows

Until then, the structure often operates without friction.

This timing creates false confidence. Founders assume that years of uneventful operation validate the arrangement. In reality, those years simply lacked economic incentive for scrutiny.

Imagine a founder who had operated through an overseas holding company for years. Nothing was ever questioned, until distributions started increasing substantially. At that point, the authorities did not dispute the legality of the entity itself; instead, they focused on whether the entity had any independent commercial rationale, given the way decisions had been made all along.

PPT is activated by scale, not by design.

What authorities actually examine when money starts moving

When PPT is applied, authorities do not dissect individual documents in isolation. They assess the arrangement as a whole.

They look at:

●      How decisions are made

●      Where risk is genuinely controlled

●      Whether the commercial narrative aligns with operational reality

Board minutes, agreements, and opinions form part of the picture, but they do not dominate it.

This is where founders often feel blindsided. They have documentation for everything. Yet the review focuses on patterns rather than paperwork.

One founder described the experience as being judged on behaviour rather than intent. Pricing authority, market entry decisions, and capital allocation had consistently come from one location, even though the holding structure suggested otherwise. Over time, this behavioural consistency outweighed formal governance records. Under PPT, coherence matters more than completeness.

The holding company problem no one flags early enough

Interposed holding companies are where PPT questions surface most often. Early on, these entities serve clear purposes. Investor familiarity, treaty access, or regional consolidation are common drivers.

The issue is not why the holding company was created. It is what happens after.

In many founder-led businesses:

●      The holding entity remains static while the business evolves rapidly elsewhere.

●      Operational relevance does not deepen.

●      Decision-making does not migrate.

●      Risk ownership does not shift.

Yet the holding company continues to anchor tax benefits.

For example, a fintech founder set up a regional holding company to consolidate investment holdings and reassure investors. Years later, all operational decisions, pricing, and risk control remained in the home country. The holding company existed mostly on paper. When treaty benefits were claimed, authorities focused on the misalignment between structure and control.

This drift is rarely intentional. It happens because founders focus on growth, not structural maintenance. By the time profits scale, the holding entity’s role looks thin relative to the value attributed to it.

At that point, PPT scrutiny feels sudden, but the vulnerability has existed for years.

Why “everyone does this” is useless in a PPT review

Founders often take comfort in market practice. If peers, competitors, or even large multinationals use a similar holding company or treaty-access strategy, it feels safe. Early on, this assumption can be reinforced by advisors, legal precedent, or investor familiarity. It creates the illusion that following the crowd guarantees defensibility.

PPT operates on a different principle. Authorities do not assess whether a structure is common. They assess whether it makes commercial sense for this specific business, given how it actually operates. A structure may be popular in the market, but if it is misaligned with your company’s decision-making, risk ownership, or operational footprint, it remains vulnerable. Popularity alone cannot justify intent.

This risk becomes particularly visible when founders rely more on precedent than introspection. One founder shared how their overseas holding company mirrored common practice in the sector. They assumed it would never be questioned. Yet when profits scaled and dividend flows were scrutinized, the authorities asked hard questions about why that entity even existed. Citing industry norms carried no weight. The structure’s role in actual operations, which was thin and transactional, dominated the evaluation.

In short, following the herd may feel safe during setup, but PPT judges substance over popularity. Being market standard is not a shield. Defensibility comes from alignment between form, function, and intent, not from the number of peers doing the same thing.

Where Control Does Not Match Substance, Risk Persists

Once PPT risk becomes apparent, founders often try to fix it by creating substance. Offices are leased, teams are hired, and governance processes are formalised. On paper, it can look convincing. Many founders assume that visible activity automatically signals legitimacy.

Substance is important, but it is not decisive. Authorities look past physical presence and ask where judgement actually sits. Who sets the pricing strategy? Who approves major investments? Who bears the downside when risks materialize? If the answers consistently point to a different entity or location than the one claiming treaty benefits, all the offices and staff become symbolic rather than substantive.

For instance, a founder added offices, staff, and governance processes in a jurisdiction to strengthen treaty defensibility. Despite visible substance, authorities noted that all strategic decisions and capital allocation remained centralized elsewhere. The added offices and teams did little to mitigate the PPT risk because real control never moved.

Under PPT, substance only matters when it aligns with genuine control. Without alignment, adding visible structures is theatre and does little to reduce risk. Defensibility depends on where decisions, risk, and authority truly reside, not where meetings are held or staff are employed.

How PPT quietly shows up through audits, banks, and investors

PPT rarely reaches founders as a direct tax notice. It often appears indirectly, through routine processes:

●      Auditors examining where management and control genuinely reside

●      Banks probing operational authority during KYC checks, account openings, or cross-border transactions

●      Investors evaluating potential tax leakage on distributions or exits

Auditors often become the first early-warning signal. During financial audits, they examine where management and control genuinely reside. They ask questions about decision-making authority, risk ownership, and the flow of capital between entities. The goal is to verify that what the filings show matches reality, and any discrepancies can raise flags under PPT.

Banks also play a role, particularly during KYC checks, account openings, or cross-border transactions. They scrutinize the structure to ensure compliance with regulatory expectations, and questions about where authority sits can uncover PPT vulnerabilities even before a tax authority intervenes.

Investors, especially global funds, bring their own layer of scrutiny. They are focused on outcomes: will distributions, dividends, or exit proceeds face unexpected tax leakage? PPT considerations influence their confidence in the structure, which in turn affects financing, valuation, and deal timing.

In one case, a global consumer tech founder received repeated questions from auditors about where key commercial decisions were made. Banks conducting KYC checks asked for clarification on operational authority, and international investors probed whether distributions could be delayed or taxed differently. Though no tax notice had been issued, these interactions revealed PPT vulnerabilities early.

Each stakeholder approaches the issue from a different perspective, yet all converge on a single question: is the structure defensible if challenged? Founders who cannot provide consistent, credible answers across audits, banking, and investor inquiries often face operational friction and pressure, even if no formal tax challenge has been raised. In many cases, this indirect scrutiny exposes PPT risks long before they crystallize into a formal dispute.

When nothing is invalid, but the economics still break

One of the most misunderstood aspects of the Principal Purpose Test is how it affects outcomes. Denial of treaty benefits does not invalidate the entity or dismantle the structure. Legally, everything remains intact. Contracts, filings, and corporate existence are unaffected.

What changes is the economics. Withholding taxes may increase, exemptions can be denied, and the efficiency of exits or repatriations can be significantly reduced. These changes can materially impact cash flows, returns to investors, and the financial logic of previously planned transactions.

For instance, A founder-led business structured to maximize treaty benefits successfully complied with all rules for years. At the time of exit, the expected withholding tax relief was denied under PPT. The company, its contracts, and operations remained valid, but the economics shifted significantly, reducing proceeds available to investors. For founders, this often creates a deep sense of frustration. The structure is compliant, operates smoothly, and has passed audits, yet the expected financial benefit disappears precisely when it is most needed during distributions or a strategic transaction.

The key takeaway is that PPT is not about punishing illegality. It is about neutralising advantage. The rule evaluates whether the arrangement was genuinely structured for operational purposes, or whether tax benefit was a principal driver. Even perfectly legal entities can face economic consequences if the arrangement’s purpose cannot be convincingly defended.

The only question that matters under PPT

At its core, PPT asks a single question. If the tax benefit were removed, would this structure still make sense in the way the business actually operates today?

Founders rarely revisit this question as the company evolves. Structures are set early, while businesses transform continuously.

Technically valid structures fail when that gap grows too wide. PPT simply exposes it, usually late, and usually at scale.

For founders, the lesson is not about mastering treaty language. It is about ensuring that structure, control, and commercial reality continue to move together. Under PPT, defensibility matters far more than technical correctness
