Before disputing an adjustment, separate factual differences from statutory appeal rights.
Before acting, read the specific notice or assessment you have received and verify current procedures with HASiL. Individual circumstances may change the appropriate response.
At a glance
- Start with the actual notice or return, not assumptions about the case.
- Keep a dated record and safeguard original documents.
- Verify relevant procedures with HASiL before taking formal action.
- Seek qualified advice where deadlines, disputed assessments or investigations are involved.
Read the reasons
Request a clear computation and legal basis for the suggested adjustment.
Prepare an evidence table
Link each disputed amount to documents, dates and your explanation of the treatment.
Identify the stage
Comments on audit findings and appeals against issued assessments may follow different procedures.
Do not miss formal deadlines
Once a notice of assessment is served, obtain prompt advice on whether a formal statutory appeal is available.
When to ask for professional support
Professional advice is especially important where an official deadline is imminent, the amounts are material, multiple years are affected or the notice concerns an investigation, statutory appeal or cross-border transactions. Confirm the credentials and engagement terms of the individual responsible for regulated work.
Preserve the dispute trail
Retain the proposed computation, supporting worksheets, responses and the final notice. A discussion of proposed audit findings is distinct from a formal statutory appeal.
Common mistake to avoid
Do not treat a general explanation as a substitute for checking the assessment year, actual document, applicable legislation and any current practice direction. An enquiry does not suspend statutory deadlines.

Source and scope check
Start with the exact notice, assessment year, date of service and legal provision. Formal requirements may differ by tax type, assessment category and the facts of the case; consult current HASiL information before action.
