7.02.840 Frivolous Filing.

A $500.00 penalty will be assessed if a taxfiler takes a "frivolous position" in respect to preparing the taxfiler’s tax return.  A tax return is considered frivolous if a taxfiler does not provide information on which the substantial correctness of the self-assessment may be judged or if the tax return contains information that on its face indicates that the self-assessment is substantially incorrect.  Examples of “frivolous positions” as provided in Oregon Administrative Rule 150-316.992(5) are hereby adopted by direct reference.
