The following conclusion: The search results currently provided do not specifically list detailed information on individual income tax anti-tax evasion cases. Therefore, no specific case could be provided.
I'm not aware of a large number of Japanese light novels specifically centered around tax evasion. But in a broader sense, in some business - themed or mystery light novels, tax evasion could potentially be a sub - plot. For example, in a mystery light novel where the detective is investigating a financial fraud case, tax evasion could be part of the illegal activities that the perpetrator is involved in.
