Reporting concerns
The reporting guide explains deliberate inaccuracies, relevant evidence, confidentiality and possible reward conditions. Provide factual transaction records rather than assume a disputed private transaction proves tax fraud.
Investigation information
The investigation guide explains officers’ authority, visits, records, interviews and taxpayer duties. It is distinct from an ordinary stamp-duty amendment or refund request. Use the corresponding service to correct your own record, and review voluntary-disclosure eligibility promptly where additional duty may be due.
