If a report required by law as a basis for assessment is not forthcoming or is believed false, how shall the Commissioner proceed?

• A. Assess the proper tax on the best evidence obtainable
• B. Wait for the report to arrive
• C. Refer the matter to the Court for decision
• D. Abstain from assessment until the report is filed

Answer: (A)

When a report required for assessment is not received or is believed false, the Commissioner should determine the tax using the best evidence obtainable. This ensures the taxpayer is promptly assessed even in the absence of the required documentation, while still basing the calculation on the most credible information available. The best evidence can include prior-year returns, records the taxpayer has provided, industry norms, audited financials, third-party data, and reasonable estimates that follow the law. This approach prevents delays or gaps in collection and keeps the process fair by grounding the assessment in solid, traceable information. If the missing or challenged report later becomes available or new data emerges, the assessment can be revisited and adjusted accordingly.
