Questione giuridica chiave
Whether the omitted liquidation proceeds amounted to attempted tax evasion for direct federal tax despite no final assessment yet.
Decisione estratta
Yes. Attempted tax evasion under federal tax law requires intent; by signing the return without checking it, the taxpayer acted at least with eventual intent.
Motivazione estratta
The return was incomplete and the taxpayer had to expect the authorities would rely on it. Signing without review created a high risk of omission; this was not mere negligence.
