Audit Trail for Transfer Pricing
An audit trail in transfer pricing software is a chronological record of changes made to calculations, assumptions or documentation, capturing who made each change, when it occurred and, where entered, the reason for it. It supports defensibility during tax authority review by allowing a specific historical figure or policy.
Audit trail functionality typically logs changes at the field or record level, capturing the previous value, new value, user identity and timestamp whenever an input such as an allocation key, mark-up percentage or benchmarking range is amended. Unlike a spreadsheet, where earlier versions may simply be overwritten or saved.
During an audit or enquiry, tax authorities may ask why a particular charge or margin changed between periods. A robust audit trail allows the team to retrieve the exact change history, showing the date, responsible person and stated rationale, which is generally more persuasive than reconstructing the explanation.
In practice
What matters when applying audit trail for transfer pricing
- Logs changes at the field or record level
- Captures user identity, timestamp and reason
- Preserves complete history without manual versioning
- Supports retrieval during tax authority enquiries
- More persuasive than reconstructed explanations
Frequently asked
Common questions
Why does an audit trail matter more in software than in Excel?+
Spreadsheets are often overwritten or saved under new file names without a systematic change log, making it difficult to reconstruct history. Dedicated software captures changes automatically at the field level, providing a reliable, tamper-resistant record.
What information should an audit trail capture?+
At minimum, it should capture the field changed, the previous and new values, the user who made the change, the timestamp, and ideally a stated reason, giving reviewers enough context to understand not just what changed but why the change was made.
