        (2) Failures subject to penalty. The following
    
failures are subject to the penalty imposed in paragraph (1) of this subsection (a):
            (A) any failure to file an information return
        
with the Department on or before the required filing date, or
            (B) any failure to include all of the information
        
required to be shown on the return or the inclusion of incorrect information.
    (b) Reduction where correction in specified period.
        (1) Correction within 60 days. If any failure
