Safe Harbour

Law and regulation are often written in broad terms, which leaves honest firms unsure whether their conduct is acceptable. A safe harbour removes that doubt by saying that anyone who follows a defined set of steps will be treated as compliant, whatever the wider argument. Examples differ by field: tax authorities may accept set transfer-pricing margins for small related-party deals, securities laws may protect forward-looking statements that carry proper warnings, and online platforms may avoid liability for user content if they act on notices. Staying inside the safe harbour is optional, and falling outside it does not mean the conduct is unlawful, only that it must be defended on its merits. Conditions are read strictly, so a missed step can lose the protection. Advisers use it to decide whether a planned step needs a formal ruling or can simply follow the published conditions.

A tax authority publishes a safe harbour for routine back-office services between group companies: a cost-plus mark-up within a stated range is accepted without further review. A multinational charges its subsidiary within that range and documents the services. The return passes without challenge, whereas a mark-up outside the range would have been examined in detail.
