## Checking plan

**Lawyer review required**

The responsible lawyer reviews the work against the instructions, sources and intended use.

- What the AI does: From the notices of assessment, the client’s entity type and turnover for each year, populate the validated diary with each income year, the period of review start date and the last day for an amendment request, and flag years whose period is about to end.
- What the lawyer does: The lawyer confirms the entity’s classification for each year and any exception that extends or removes the time limit, and decides whether an amendment request should be lodged before the period ends.
- Who reviews: Responsible lawyer with competence in the matter
- Basis: Practical workflow informed by the linked primary sources; the traffic light and working checks are editorial guidance, not a court classification.
- Why: The level reflects what the work is, the consequence of an error, and how much of the output the lawyer must independently re-derive.

## Checks the lawyer makes

1. Confirm client tax file numbers, ATO correspondence and financial records go only into a tool approved for client tax data, and that privileged advice is not uploaded where privilege could be lost.
2. Check each notice date against the notice itself.
3. Confirm the entity’s classification for each year.
4. Check exceptions (fraud or evasion, specific provisions) before relying on a closed period.

## Notes

- These are suggested working checks. Confirm the required checking with the responsible lawyer before work starts; the checking approach does not establish permission to use AI.
