Substance Requirements

Decision-making, people, and operational reality

Substance is the bridge between legal form and tax credibility. It is the set of facts that shows whether an entity genuinely performs the role assigned to it, or whether the structure depends on documents that are not matched by people, decisions, assets, and risk-bearing capacity.

Overview

There is no universal single checklist for substance, which is why it often becomes a litigation issue rather than a box-ticking exercise. The relevant indicators depend on the tax question: a holding company claiming treaty benefits, an IP entity earning residual return, a finance company taking significant credit risk, or a service center charging cost-plus all require slightly different evidence of real activity.

For tax teams, the useful approach is functional rather than cosmetic. Instead of asking only whether there is office space or a local director, ask whether the entity can genuinely make and execute the decisions that matter to its income. That framing is far stronger across treaty, transfer pricing, CFC, and anti-abuse analysis.

How Uncle Louis helps

Substance analysis is strongest when governance records, contracts, emails, and operating evidence are reviewed together. The platform gives teams a practical way to organize that evidence around the tax position being defended.

Useful outputs for platform users

A substance review memo linked to treaty claims, transfer pricing, or CFC defense.
A governance and evidence checklist for boards, local management, and operational teams.
A remediation plan showing which decisions, people, or records need to move or improve.

When this topic matters

A holding, financing, or IP entity earns meaningful income but has limited local staff or governance depth.
Directors formally approve transactions locally while commercial strategy and negotiation happen elsewhere.
The group wants treaty relief, low-risk transfer pricing returns, or CFC protection for entities with light operating footprints.
Authorities or auditors are asking for evidence of who made decisions, who monitored risk, and where core functions sit.

Common risk flags

Key strategic and risk decisions are prepared and effectively made outside the entity's jurisdiction.
Local directors have limited knowledge of the transactions they approve or no practical ability to reject them.
High-value income is booked in an entity with little budget, weak systems, and no operational ownership of the activity.
Substance arguments rely on templates and formalities rather than recurring evidence of real execution.

How the analysis should be structured

Define the role the entity is meant to perform

Start from the claimed business purpose and income profile so the substance review tests the right decision-making and capabilities.

Map people, governance, and assets

Identify who takes the key decisions, where they sit, what resources they control, and whether local records support that story.

Compare form with conduct

Check whether agreements, board minutes, delegated authority, and real execution align or point in different directions.

Build an evidence package

Assemble the records that a reviewer would expect to see, from staffing and premises to approvals, monitoring, and economic outcomes.

Questions users typically ask

Does this holding company have enough real activity to support treaty access and dividend planning?

What evidence would best support the claim that the IP company controls its risks and decisions?

Which local governance changes would materially strengthen substance without redesigning the whole structure?
