BDO Transfer Pricing News

On 31 March 2026, Inland Revenue released updated transfer pricing documentation guidance clarifying what it considers to be adequate documentation for New Zealand purposes. While New Zealand law has not changed, Inland Revenue has strengthened and clarified its administrative expectations, particularly regarding the quality and localisation of supporting documentation. The update is best understood as part of Inland Revenue’s multi‑year transfer pricing compliance programme, rather than a shift in legislative policy.

No New Filing Obligation but Clearer Expectations

New Zealand still does not require transfer pricing documentation to be filed annually with the tax return. However:

• The burden of proof for transfer pricing matters rests with the taxpayer.
• Taxpayers are expected to have documentation prepared to support positions taken, and documentation must be provided upon request, typically as part of a risk review or audit. Weak documentation will make it more difficult to rebut Inland Revenue’s alternative pricing position.

This reflects Inland Revenue’s long‑standing position under New Zealand’s self‑assessment regime, but the updated guidance is more explicit about the consequences of poor quality, incomplete or centrally prepared documentation that has not been localised for the New Zealand market. This represents a practical tightening rather than a doctrinal change, consistent with international trends in transfer pricing enforcement.

Greater Emphasis on “New Zealand‑Specific” Analysis

A key feature of the updated guidance is Inland Revenue’s emphasis on local relevance. In particular, Inland Revenue has expressed concern about over‑reliance on:

• Centrally prepared “regional” or “global” local files; and
• Generic functional analyses that do not reflect how the New Zealand business actually operates.

The guidance reiterates that:

• Documentation must be appropriately localised and include sufficiently tailored details for the New Zealand operations.
• Local management is expected to validate factual accuracy.
• Omissions or inconsistencies between global documentation and New Zealand reality will increase audit risk.

Therefore, while New Zealand continues to apply its transfer pricing rules consistently with OECD guidelines, it is explicit that Inland Revenue will not merely “accept” OECD‑aligned documentation as sufficient by default and will scrutinise whether OECD‑style documentation actually reflects New Zealand facts and risks.

Penalties Are Now Framed As “Likely,” Not Merely Possible

One of the most material changes is a shift in penalty language. Previously, Inland Revenue indicated that inadequate documentation may result in penalties. The updated guidance states that where documentation is inadequate and a transfer pricing adjustment is made, shortfall penalties will most likely apply. In particular, Inland Revenue highlights the potential application of a 40% shortfall penalty for gross carelessness, particularly where there is a failure to prepare adequate transfer pricing documentation or acceptance of pricing that is clearly inappropriate.

This change does not introduce new penalties, but it clearly signals a lower tolerance for documentation deficiencies.

What This Means in Practice

For New Zealand‑based taxpayers with material cross‑border associated party transactions, the updated guidance reinforces several practical points:

• Documentation should be prepared on a timely basis to support the position taken.
• Local files should be reviewed and updated regularly, not rolled forward mechanically.
• Functional analyses, risk allocation and benchmarking should reconcile to New Zealand financial statements and actual operational decision making.
• Groups relying on global documentation should ensure it is supplemented with a New Zealand overlay.

For many taxpayers already following robust annual review processes, the update largely confirms existing best practice. For others, it elevates documentation from a defensive afterthought to a core compliance obligation.

BDO Perspective

While there has been no legislative change to New Zealand’s transfer pricing rules, Inland Revenue’s updated guidance represents a clear escalation in documentation expectations and enforcement posture. Taxpayers should treat the update as a signal that, going forward, contemporaneous and quality transfer pricing documentation will play a central role in risk assessment, audits and penalty outcomes.
