Does mere underdeclaration automatically establish falsity under Section 222(a) when pursuing a ten-year prescriptive period?

Does mere underdeclaration automatically establish falsity under Section 222(a) when pursuing a ten-year prescriptive period?

• A. Yes.
• B. No.
• C. Only if underdeclaration exceeds a threshold.
• D. Only if confirmed by a fraud examiner.

Answer: (B)

The main idea here is that the long look-back window isn’t triggered by underreporting alone. Falsity in the return—usually shown by deliberate misstatement or concealment of income with the intent to evade tax—is what can justify extending the period to reopen assessment. Merely underdeclaring income can be an error or incomplete disclosure, not automatically proof of falsity. So you don’t get a ten-year prescriptive period just because the figures were understated. In practice, whether underdeclaration amounts to falsity depends on showing that the return contained a false statement or concealed information with the aim of evading tax. That doesn’t require a fraud examiner’s certification or a fixed threshold of underdeclaration; it rests on the evidence of intentional misstatement or concealment. That’s why the correct stance is that mere underdeclaration does not automatically establish falsity.
